  • Trajectories of risk behaviors across adolescence and young adulthood: The

      Introduction Despite important advances of longitudinal research in substance use behaviors, most studies stratify analyses by gender or race, which limits the ability to directly compare the likelihood of a particular developmental pathway across demographic groups. Thus, there is critical need for well-designed research to examine the associations of race/ethnicity with developmental trajectories of substance use behaviors across adolescence through adulthood. Methods Using an accelerated longitudinal design, we examined behaviors across ages 12–31 from Waves I–IV of the National Longitudinal Study of Adolescent to Adult Health. We performed growth mixture modeling, resulting in estimated trajectories over time. Next, we assessed the association between race/ethnicity and trajectory membership using multinomial logistic regression. Results Five trajectories resulted for marijuana use, four for cigarette smoking, three for smokeless tobacco use and number of days drunk, and two trajectories for heavy episodic drinking. Controlling for gender and family socioeconomic status, African Americans and Hispanics were less likely than non-Hispanic Whites to use cigarettes or smokeless tobacco early or to use alcohol heavily. Conclusions Substance use behavior development follows different pathways for US adolescents and young adults, with some individuals experimenting earlier in adolescence and others beginning to use later in adolescence or in early adulthood. We extend developmental knowledge about these behaviors by demonstrating that the patterns of behavior vary by race/ethnicity; members of lower-risk trajectories (those involving later or no initiation of substance use) are more likely to be African American or Hispanic than to be non-Hispanic White.

      Background Opioid use disorder (OUD) is a significant public health problem, and opioid maintenance treatment (OMT) on methadone or buprenorphine is a common approach. This study characterized sleep impairment in patients maintained on methadone or buprenorphine, and evaluated its association with psychiatric and medical comorbidities. Methods Participants (N=185) maintained on methadone (N=125) or buprenorphine (N=60) for OUD completed the Medical Outcomes Study Sleep Scale (MOS) to provide a point-prevalence assessment of sleep impairment. Measures of lifetime problems and current functioning were also examined and compared as both a function of OMT and level of sleep impairment. Results Participants reported high levels of sleep impairment on the MOS, including not getting the amount of sleep they needed (42.9%), not sleeping enough to feel rested (39.6%) and trouble falling asleep (23.3%) or falling back asleep after waking (25.8%). Few differences were observed between OMT groups, and psychiatric dysfunction emerged as the most robust predictor of sleep impairment ratings. Patients with sleep impairment, independent of OMT medications, also reported current opioid withdrawal, psychiatric impairment, negative affect, and pain. Conclusions Results demonstrate substantial and clinically-significant impairments in sleep that are associated with a variety of current problems that could impact OMT outcomes and decrease quality of life. Outcomes support the development of methods to improve sleep in OMT patients, and to examine the degree to which sleep improvements may be associated with improvements in mood and other health-related measures.

      Introduction Non-medical prescription opioid (NMPO) use is a critical public health problem in the United States, with 2.1 million new initiates annually. Young adult NMPO users are at high risk for initiating injection drug use. We assessed correlates of injection drug use among young adult NMPO users in Rhode Island, a state heavily impacted by opioid overdose. Methods We used data from the Rhode Island Young Adult Prescription Drug Study (RAPiDS), which recruited 199 residents aged 18–29 who reported past-30-day NMPO use (65.3% male). We compared individuals who reported ever having injected with individuals who reported never injecting, using logistic regression to identify independent correlates of injection. Results Among eligible participants, the mean age was 24.6years and 61.3% were white. Over one-quarter (n=59, 29.6%) of the sample had ever injected drugs. The majority (n=46, 78.0%) of participants who had ever injected drugs reported injecting heroin as her/his first drug; the majority also reported previously snorting her/his first drug that was injected (n=46, 78.0%). In multivariable analyses, white race, older age, lifetime homelessness, and ever having overdosed or seen someone overdose were independently associated with an increased likelihood of ever injecting drugs. Conclusions These findings demonstrate a high prevalence of lifetime injection drug use among young adults who use prescription opioids non-medically. Given the observed associations between injection drug use and witnessing as well as experiencing overdose, interventions are urgently needed to improve overdose education and naloxone distribution to young adult NMPO users who inject drugs.

      Introduction College students are at higher than average risk for nonmedical use of prescription stimulants (NPS). A commonly identified motive among students who engage in NPS is to improve grades. Several research studies have observed that NPS most likely does not confer an academic advantage, and is associated with excessive drinking and other drug use. This study documents the proportion of the general college student population who believe that NPS will lead to improvements in academic performance. Methods This study gathered online survey data from a large, demographically diverse sample of college students to document the prevalence of perceived academic benefit of NPS for improving grades and to examine the association between such belief and NPS. Results Overall, 28.6% agreed or strongly agreed that NPS could help students earn higher grades, and an additional 38.0% were unsure. Students with a higher level of perceived academic benefit of NPS and more frequent patterns of drinking and marijuana use were more likely to engage in NPS, even after adjustment for a wide range of covariates. Conclusions The results underscore the need for interventions that simultaneously correct misperceptions related to academic benefit and target alcohol and marijuana use to reduce NPS.

      The field of gambling studies has extensively focused on isolating risk factors for developing a gambling disorder. Conversely, little attention has been paid to identifying protective factors against gambling disorder among people who choose to not gamble at all. Moreover, the limited number of studies that have focused on non-gamblers have neglected to differentiate current from lifetime non-gamblers. The purpose of the present study was to examine motives for not gambling among a diverse sample of adult lifetime non-gamblers recruited from the community and to compare these motives to an undergraduate student sample of non-gamblers from a previous study. Participants consisted of 219 lifetime non-gamblers (45.2% male) from the United States recruited via Amazon's Mechanical Turk. The previously recruited sample consisted of Canadian undergraduate students (n =196). Eight distinct categories of motivations for not gambling were identified in the sample of adult community non-gamblers, which corresponded closely with previous findings from the student sample. However, comparisons between the two samples revealed that adult lifetime non-gamblers were more likely to provide financial motives as reasons for not gambling. Whereas, the student sample was more likely to mention disinterest and the influence of others as reasons to avoid gambling. Results suggest that the choice not to gamble among lifetime non-gamblers may reflect a more conscious, values-based decision when compared to undergraduate non-gamblers.

      Cannabis is the most widely used illicit substance in the United States. Regular cannabis use appears to be a dynamic, chronic process consisting of multiple quit attempts, periods of reduction, periods of abstinence, and periods of continual use. Cannabis-related processes, including withdrawal, problematic consequences of use, and self-efficacy for quitting each contribute to the cycle of use and, in part, are maintained and reinforced by perceived barriers for cannabis cessation. Yet, no work has examined the association between perceived barriers for cannabis cessation and clinically-relevant processes related to cannabis use. To address this gap, the current study recruited a racially diverse sample (N =145, 63.4% Black or African American) of cannabis users from the community to test the hypothesis that greater perceived barriers for quitting cannabis was related to more cannabis use problems, more cannabis withdrawal symptoms, and lower self-efficacy for quitting cannabis. Structural equation modeling suggested that greater perceived barriers for quitting cannabis was uniquely associated with cannabis use problems (β =0.50, 95%CI [0.39, 0.65], p <0.001), greater withdrawal symptoms (β =0.39, 95%CI [0.30, 0.50], p <0.001), and lower self-efficacy for quitting (β =−0.17, 95%CI [−0.21, −0.02], p =0.028). The results of this study indicate perceived barriers for cannabis cessation may help in better understanding an array of clinically significant cannabis use processes. Indeed, the observed pattern of findings add to current theoretical models of substance use that aim to identify unique risk processes that may maintain substance use and provide valuable information that can be used to inform treatment for cannabis users.

      Introduction Four post-hoc analyses of prior trials found smokers using nicotine patch following a lapse were less likely to progress to relapse compared to those using a placebo patch following a lapse. We attempted a conceptual replication test of these results via a randomized trial of instructions to continue vs. stop nicotine patch after a lapse. Methods Smokers trying to quit (n =701) received nicotine patch (21/14/7mg) and brief phone counseling (six 15-min sessions). We randomized smokers to receive instructions for and rationale for stopping vs. continuing patch after a lapse. The messages were repeated before and after cessation and following lapses via counseling, phone and written instructions. Results Among those who lapsed, those told to Continue Patch did not have a greater incidence of 7-day abstinence at 4months (primary outcome) than those told to Discontinue Patch (51% vs. 46%). Most (81%) participants in the Discontinue condition stopped patch for only 1–2days and then resumed abstinence and patch use. Analyses based on all participants randomized were similar. Adverse events were as expected and did not differ between conditions. Conclusion Instructions to continue nicotine patch after a lapse did not increase return to abstinence. These negative results may have occurred because actual use of patch after a lapse was similar in the two conditions. Also, allowing patch use while smoking may have reduced motivation to stay abstinent.

      The earliest experiences with alcohol for many children occur in the family context with parental supervision. The current study examined individual and sociocultural characteristics associated with early (prior to age 13years) sipping and tasting alcohol with parental permission in two longitudinal community samples. Early sipping/tasting was also tested as a predictor of frequency and quantity of alcohol use, and alcohol-related problems seven years later in late adolescence. Early sipping/tasting with parental permission was associated with a sociocultural context supportive of alcohol use (e.g., parental alcohol use, permissive rules about alcohol use in the home, parental attitudes about underage drinking, perceived peer norms), adolescent sensation seeking and disinhibition (e.g., surgency, externalizing behavior) and appraisals of alcohol (negative outcome expectancies and negative implicit alcohol associations). Early sipping/tasting predicted increased frequency and quantity of alcohol consumption, and increased alcohol-related problems in late adolescence, even after controlling sociocultural and individual difference variables. Findings suggest that early sipping/tasting with parental permission is not benign and is a viable target for preventive interventions.

      Drinking identity, or the tendency to view one's self as a drinker, is a unique predictor of alcohol use and related consequences among young adults; yet the mechanism by which it leads to alcohol problems is poorly understood. Based on self-presentation and self-verification perspectives, we examined drinking to cope as a mediator of the association between explicit drinking identity and alcohol-related problems among two samples of young adults. Study data come from two large, longitudinal studies. Participants from Sample 1 and Sample 2 included undergraduates (55% and 59% female, respectively) who reported drinking in the previous three months. Tests of the indirect effects indicated that 3-month drinking to cope significantly mediated the positive association between baseline drinking identity and 6-month alcohol-related problems in both samples. In contrast, 3-month drinking identity did not mediate the association between baseline drinking to cope and 6-month alcohol-related problems. Findings indicate that individuals with a stronger drinking identity are more likely to use alcohol to cope and, subsequently, experience more problems. Thus, drinking identity may be an important intervention target for college students as it appears to temporally proceed drinking to cope in the prediction of alcohol-related problems.

      Introduction Subjective effects of drugs, representing pharmacological and non-pharmacological effects, have been shown to be associated with future use and abuse. This also is the case for tobacco products and so measuring subjective effects, such as liking, satisfaction, and aversion, is crucial to gaining an understanding of consumer perception leading to increased use. This study examined the predictive validity of subjective drug and product effects with respect to product adoption. Methods Smokers (N=151) were enrolled in Minneapolis, Columbus, and Buffalo. Participants were shown two snus products (Camel Snus Winterchill and Robust), asked to try each of the products for 5min and to rate them using the Product Evaluation Scale (PES) and Drug Effects Questionnaire (DEQ). This was followed by a one-week use period of their preferred product and those who used at least 1 unit of Camel Snus per day (or at least 7 pouches total) were eligible to enroll in the Clinical Trial Phase assessing the impact of complete switching or dual use with smoking. Key outcomes for this study were product evaluation, extent of product use, and Clinical Trial enrollment. Results We noted no relationships between participant characteristics such as gender, age, prior smokeless use, baseline cigarettes per day (CPD), or PES and DEQ scores with any of these outcome variables. Subjective effects were weak predictors of product use, which totaled approximately 3units of snus per day. Conclusions Regardless of product, it appears that PES and DEQ ratings were uniformly poor predictors of trial enrollment and retention, though they do predict the amount of snus used during the sampling phase. Findings indicate that while subjective effects predict product preference in the short-term, they did not consistently predict extent of use or enrollment in the trial, suggesting that these initial measures have limited implications for long-term behavior.

      Background Risky sexual behaviors (e.g., sex without protection against pregnancy or sexually transmitted infections, sexual coercion, sex with unknown partners) are common among college students. To effectively decrease these behaviors, it is necessary to further understand factors associated with their occurrence. Drinking motives are a known predictor of both alcohol use and alcohol-related consequences, which may theoretically include risky sex. This study aimed to understand how drinking motivation interacts with alcohol use to predict risky sexual behaviors among college student drinkers. Methods One-hundred and eight primarily female (83.3%) college students (age: M =19.09, SD =1.16) who endorsed past-month alcohol use and lifetime history of sexual activity completed up to four weekly Internet surveys assessing daily quantity of alcohol use, drinking motives (i.e., social, enhancement, coping, conformity), and engagement in risky sexual behavior. From 403 reported drinking episodes, four Generalized Estimating Equations were used to predict risky sex from person-centered drinking quantity and drinking motives. Results Strong social motives significantly increased the odds of engaging in risky sexual behaviors (p =0.004). Additionally, there was a significant interaction, such that the relationship between risky sex and drinking depends on enhancement motives (p =0.021). Conclusions Interventions targeting social and enhancement motives for drinking may be particularly effective in reducing the occurrence of risky sexual behaviors among college students, which may result in a reduction of the negative physical and psychological health outcomes accompanying these behaviors.

      Electronic cigarette use, or vaping, continues to be a focus for regulators and policy makers in public health, particularly since it can compete with or be a substitute for smoking. This study investigated characteristics of nicotine dependence and consumption in a sample of vapers who formerly smoked cigarettes. We recruited 436 (80% male) vapers from several internet discussion forums; 95% of whom previously smoked, but ceased after commencing vaping. These participants completed a retrospective version of the Fagerström Test for Nicotine Dependence (FTND-R), as well as a version modified to suit current vaping (FTND-V), along with measures of consumption. Nicotine dependence appears to reduce markedly when smokers transition to vaping. However, ‘decoupling’ is observed in the relationship between consumption and dependence in vaping, and the FTND-V showed inadequate psychometric properties. Older and female vapers tend to employ a low-power, higher nicotine-concentration style of vaping. Overall, nicotine concentration tended to increase over time, although this effect was moderated by users' intentions to reduce their intake. Indicators of smoking addiction do not appear to be applicable to vaping, with respect to both internal consistency and relationship to consumption. This suggests that motivations for vaping are less dominated by nicotine delivery (negative reinforcement), and may be driven more by positive reinforcement factors. Nevertheless, e-liquid nicotine concentration was associated, albeit weakly, with dependence among e-cigarette users. Finally, vapers are heterogeneous group with respect to style of consumption, with a high-power/lower nicotine set-up more common among younger men.

      It is widely recognized that smoking is related to abdominal pain and discomfort, as well as gastrointestinal disorders. Research has shown that visceral sensitivity, experiencing anxiety around gastrointestinal sensations, is associated with poorer gastrointestinal health and related health outcomes. Visceral sensitivity also increases anxiety symptoms and mediates the relation with other risk factors, including gastrointestinal distress. No work to date, however, has evaluated visceral sensitivity in the context of smoking despite the strong association between smoking and poor physical and mental health. The current study sought to examine visceral sensitivity as a unique predictor of cigarette dependence, threat-related smoking abstinence expectancies (somatic symptoms and harmful consequences), and perceived barriers for cessation via anxiety symptoms. Eighty-four treatment seeking adult daily smokers (Mage =45.1years [SD =10.4]; 71.6% male) participated in this study. There was a statistically significant indirect effect of visceral sensitivity via general anxiety symptoms on cigarette dependence (b =0.02, SE =0.01, Bootstrapped 95% CI [0.006, 0.05]), smoking abstinence somatic expectancies (b =0.10, SE =0.03, Bootstrapped 95% CI [0.03, 0.19]), smoking abstinence harmful experiences (b =0.13, SE =0.05, Bootstrapped 95% CI [0.03, 0.25]), and barriers to cessation (b =0.05, SE =0.06, Bootstrapped 95% CI [0.01, 0.13]). Overall, the present study serves as an initial investigation into the nature of the associations between visceral sensitivity, anxiety symptoms, and clinically significant smoking processes among treatment-seeking smokers. Future work is needed to explore the extent to which anxiety accounts for relations between visceral sensitivity and other smoking processes (e.g., withdrawal, cessation outcome).

      Objective Parental monitoring is a well-established protective factor for adolescent drinking. This study examined whether parental monitoring protected against three common risk factors for alcohol use in a sample of high-risk adolescents: parental depressed mood, adolescent depressed mood, and parental alcohol use. Methods Participants included 117 adolescents (mean age=15.5; 52% female) who presented to the hospital emergency department due to an alcohol-related event and their primary parent/guardian. Adolescents completed self-report measures of alcohol use frequency, depressed mood, and parental monitoring, while parents completed self-report measures of problematic alcohol use and depressed mood. Results Hierarchical regression confirmed that parental monitoring was associated with lower frequency of adolescent alcohol use, even after controlling for the three risk factors. Significant interactions were found between parental monitoring and both adolescent and parental depressed mood. Parental monitoring had significant protective effects against drinking frequency among adolescents with higher levels of depressed mood, but not among adolescents with lower levels of depressed mood. By contrast, parental monitoring only had protective effects among those parents with lower levels of depressed mood. Parental problematic alcohol use did not affect the relationship between parental monitoring and adolescent alcohol use. Conclusions Our results suggest that adolescents with high levels of depressed mood may be more likely to benefit from parental monitoring, whereas parents with high levels of depressed mood may be less likely to monitor effectively. Interventions targeting parental monitoring in high-risk adolescents should take into account the influence of both adolescent and parental depressed mood.

      In smoking cessation studies with restrictive criteria (e.g., single-smoker couples), thousands of potential participants might need to be screened to obtain a reasonable sample size. Consideration of recruitment methodology is critical because recruitment methods influence both the success and cost effectiveness of recruitment. Although traditional recruitment methods are often used to recruit participants into smoking cessation research, newer technologies, such as paid Facebook advertising, might offer more cost-effective alternatives for recruitment. The current analysis compares two versions of paid Facebook advertising and a specialized mass mailing method used to recruit single-smoker couples into an intensive three-week study of unaided smoking cessation. The three methods are compared in terms of demographic characteristics, eligibility, and cost-effectiveness. Although Facebook's “Promote Your Page” mechanism achieved the fastest recruitment rate (2.75 couples per month; 498 USD per couple), Facebook's “Send People to Your Website” mechanism was the least expensive and provided the most demographically diverse sample (1.64 couples per month; 181 USD per couple). The specialized mailing method was not productive or cost-effective (0.80 couples per month; 454 USD per couple). Paid Facebook advertising fared better as a recruitment method than a specialized mailing method often used in survey research. Studies that have less restrictive eligibility criteria, that draw from a larger local population, or that recruit for a less intense study might find paid Facebook advertising to be quite feasible.

      Purpose The current study examined whether the interaction of lower respiratory symptoms and anxiety sensitivity is related to smoking lapse in the context of smoking cessation. Method Participants were adult daily smokers (N =60) exposed to the World Trade Center (WTC) disaster who were in a smoking cessation treatment program (75.0% male, 50.6years old [SD =9.2], and current smoking rate was 17.6 cigarettes per day (SD =10.6). Results Results indicated that the interaction between lower respiratory symptoms and anxiety sensitivity was a significant predictor of greater risk for lapse (i.e., lower survival time; B =0.005, OR =1.01, p =0.039). Follow-up analysis showed that greater respiratory symptoms were a significant predictor of lapse risk among those with high (B =0.116, OR =1.12, p =0.025), but not those with low (B =−0.048, OR =0.95, p =0.322), levels of anxiety sensitivity. Discussion The findings from the current study suggest that smokers with greater respiratory symptoms and higher levels of anxiety sensitivity may be associated with early lapse to smoking following smoking cessation treatment. Future work has the potential to inform the development of tailored cessation interventions for smokers who experience varying levels of lower respiratory symptoms and anxiety sensitivity.

      Objective This study aims to identify key process variables that are associated with changes in alcohol consumption and mental health symptoms over 12months following personality-targeted interventions in youth. Method 154 high-risk youth (aged 12–13years) in 7 Montreal high schools were identified using the Substance Use Risk Profile Scale and participated in personality-matched interventions. Preliminary process variables were identified using a combination of psychotherapy process variables and youth-generated (qualitative) feedback immediately post-intervention. Results Learning, skill development and a positive group experience were key to positive behavioural change. Youth-generated feedback independently accounted for 12–25% of the variance in the change in alcohol use and mental health symptoms over 12months. Changes in cognitive distortions and self-esteem accounted for somewhat less of the variance in alcohol use (0–9%), but a moderate-to-large portion of the variance in changes in mental health symptoms (up to 44%). Conclusions The study findings highlight candidate process variables relevant to future implementations of this program that might inform change processes relevant to brief interventions with youth more generally. This study suggests that youth experiences can indicate proximal measures of program efficacy, and has implications for the dissemination of this brief intervention program.

      Objective Symptoms of insomnia and heavy alcohol use tend to co-occur among military and veteran samples. The current study examined insomnia as a moderator of the association between alcohol use and related consequences among young adult veterans in an effort to extend and replicate findings observed in samples of civilian young adults. Method Young adult veterans (N =622; 83% male; age M =29.0, SD =3.4) reporting alcohol use in the past year completed measures of insomnia severity, alcohol use, and alcohol-related consequences as part of a larger intervention trial. Participants were classified as screening ‘positive’ (n =383, 62%) or ‘negative’ (n =239, 38%) for insomnia using the Insomnia Severity Index. Hierarchical regression was used to examine the interaction between drinking quantity and insomnia on alcohol-related consequences. Predictor and outcome variables were measured concurrently. Results Both a greater number of drinks per week and a positive insomnia screen were associated with more alcohol-related consequences. Drinks per week and insomnia screen interacted to predict alcohol-related consequences, such that the effect of drinking on alcohol-related consequences was stronger in the context of a positive versus negative insomnia screen. Conclusion Drinking is associated with more alcohol-related consequences in the presence of clinically significant insomnia symptoms. These findings replicate those documented in civilian young adults and indicate that insomnia may be an appropriate target for alcohol prevention and intervention efforts among young adult veterans.

      Introduction Youth with a history of child maltreatment use substances and develop substance use disorders at rates above national averages. Thus far, no research has examined pathways from maltreatment to age of substance use initiation for maltreated youth. We examined the longitudinal impact of maltreatment in early childhood on age of alcohol and marijuana use initiation, and whether internalizing and externalizing behaviors at age 8 mediates the link between maltreatment and age of substance use initiation. Materials and methods Data were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) at ages 4, 8, 12, and 18. Maltreatment was assessed through reviews of administrative records and youth self-reports. Behavior problems were assessed with the Child Behavior Checklist. Age of substance use initiation was assessed with the Young Adult version of the Diagnostic Interview Schedule for Children. Results Path analyses indicated mediated effects from a history of maltreatment to age at first alcohol and marijuana use through externalizing behaviors. Considering type of maltreatment, direct effects were found from physical abuse to age of alcohol initiation, and mediated effects were found from sexual abuse and neglect to initial age of alcohol and marijuana use through externalizing behaviors. Direct effects for marijuana use initiation and indirect effects through internalizing behavior problems were not significant for either substance. Conclusions Externalizing behavior is one pathway from childhood maltreatment to age of substance use initiation. Services for maltreated youth should incorporate substance use prevention, particularly among those with early externalizing problems.

      Introduction To examine the impact of cessation of an internet session on skin conductance responses and anxiety of higher and lower problem internet users, in order to explore possible physiological withdrawal effects. Method Participants were measured in terms of their skin conductance before (15min), during (15min), and after (15min) an internet session, and completed self-report measures of state anxiety and problematic internet use. Results Higher, but not lower, problem users showed increased skin conductance after internet use was stopped, relative to before their internet session. Higher problem users' GSR scores increased, as the time from internet cessation became longer. Higher problem users also showed increased levels of anxiety, following their internet session, which correlated with their skin conductance scores. Conclusions These results suggest that, following termination of an internet session, withdrawal-like effects are seen, both psychologically and physiologically.

      Introduction Understanding factors that influence non-cigarette tobacco use is important given these products' prevalence and health risks. The goal of this study was to test the hypothesis that personality traits related to affect regulation would be associated with greater frequency of other tobacco product (OTP) use in a sample of young adult non-daily smokers. Methods Participants (n =518, 51% male) aged 18–24 were non-daily cigarette smokers recruited from the community for a longitudinal study of tobacco use. Personality characteristics (impulsivity, anhedonia, and negative affectivity) were measured at baseline, and participants reported recent tobacco use at baseline and 3, 6, and 9months later. Assessments were conducted online or via mobile phone. Results Across the 4 assessments, 33–52% of participants reported recent OTP use, with frequency of use decreasing over time. Longitudinal negative binomial regression models indicated that greater sensation seeking and lack of premeditation were associated with more frequent OTP use (ps<0.05). These effects were consistent over time. Conclusions Findings suggest that young adult non-daily cigarette smokers with greater propensity for immediately rewarding behaviors may use OTPs more frequently. Young, non-daily cigarette smokers with high levels of sensation seeking and/or lack of premeditation may be at increased risk for harms related to OTP use and may benefit from prevention and cessation strategies that specifically address affect.

      Introduction The links between gambling problems, trauma and life stressors are known to exist but understanding the extent of these relationships will allow for greater efficacy in early intervention and treatment. We investigated these relationships among men and sought to determine whether links were attenuated by alcohol and drug use problems. Methods A cross-sectional UK representative general population survey was conducted in 2009 with 3025 men aged 18–64years. Measurements included self-reported gambling behaviours, as measured by the South Oaks Gambling Scale (SOGS) and traumatic or stressful life events. Covariates included alcohol and drug dependence and socio-demographics. Binary logistic regression models were used to examine associations. Results Problem gambling (SOGS 3–4) and probable pathological gambling (SOGS 5+) were associated with increased odds of trauma in childhood (e.g. violence in the home (Adjusted Odd Ratios (AOR) 3.0 (CI=1.8–5.0) and 2.6 (CI=1.7–4.1) respectively), and life stressors in adulthood (e.g. intimate partner violence (AORs 4.5 (CI=2.0–10.3) and 4.7 (CI=2.3–9.7) and homelessness (AORs 2.2 (CI=1.1–4.6) and 3.2 (CI=1.9–5.5)). Results were attenuated when adjusted for probable alcohol and drug dependence with the latter having largest effects. Conclusions Among men in the United Kingdom, disordered gambling remains uniquely associated with trauma and life stressors in childhood and adulthood after adjusting for alcohol and drug dependence. The results support a need for disordered gambling treatment services to undertake routine screening for alcohol, drugs, IPV and traumatic life events and to tailor treatment that specifically targets the effects of stress for clients who present with such a cluster of issues.

      High prevalence rates of tobacco use, particularly cigarettes, pose a serious health threat for individuals with serious mental illness (SMI), and research has demonstrated the effectiveness of pharmacotherapy and psychosocial interventions to reduce tobacco use in this group. However, few studies have considered predictors of tobacco cessation treatment engagement among individuals with SMI. The current study examined predictors of engagement in smoking cessation groups among veterans with SMI engaged in mental health services at three VA medical centers. All veterans were participating in a smoking cessation treatment study. Of 178 veterans who completed baseline assessments, 127 (83.6%) engaged in treatment, defined as attending at least three group sessions. Forty-one (N =41) predictors across five domains (demographics, psychiatric concerns, medical concerns, smoking history, and self-efficacy to quit smoking) were identified based on previous research and clinical expertise. Using backward elimination to determine a final multivariable logistic regression model, three predictors were found to be significantly related to treatment engagement: marital status (never-married individuals more likely to engage); previous engagement in group smoking cessation services; and greater severity of positive symptoms on the Brief Psychiatric Rating Scale. When included in the multivariable logistic regression model, the full model discriminates between engagers and non-engagers reasonably well (c statistic=0.73). Major considerations based on these findings are: individuals with SMI appear to be interested in smoking cessation services; and serious psychiatric symptomatology should not discourage treatment providers from encouraging engagement in smoking cessation services.

      Gamblers' thoughts have a fundamental influence on their gambling problem. Cognitive restructuring is the intervention of choice to correct those thoughts. However, certain difficulties are noted in the application of cognitive restructuring techniques and the comprehension of their guidelines. Furthermore, the increase of skill game players (e.g. poker) entering treatment creates a challenge for therapists, as these gamblers present with different thoughts than those of the gamblers usually encountered in treatment (e.g. chance-only games like electronic gambling machines). This systematic review aims to describe how cognitive restructuring is carried out with gamblers based on the evidence available in empirical studies that include cognitive interventions for gambling. Of the 2607 studies collected, 39 were retained. The results highlight exposure as the most frequently used technique to facilitate identification of gambling-related thoughts (imaginal=28.2%; in vivo=10.3%). More than half of the studies (69.2%) clearly reported therapeutic techniques aimed to correct gamblers' thoughts, of which 37% involved visual support to challenge those thoughts (e.g. ABC log). Of the 39 studies retained, 48.7% included skill game players (i.e., poker, blackjack, sports betting) in their sample. However, none of these studies mentioned whether cognitive restructuring had been adapted for these gamblers. Several terms referring to gamblers' thoughts were used interchangeably (e.g. erroneous, dysfunctional or inadequate thoughts), although each of these terms could refer to specific content. Clinical implications of the results are discussed with regard to the needs of therapists. This review also suggests recommendations for future research.

      Introduction While adherence to medication in smoking cessation clinical trials is strongly associated with clinical outcome, very few studies have evaluated the validity of pill count as a measure of adherence relative to a biological assay, and evaluated a broad range of correlates of adherence. Methods In a smoking cessation clinical trial of varenicline, we compared pill counts collected over 4 different time periods to varenicline salivary levels taken after 2weeks of treatment, as well as evaluated predictors of adherence to varenicline. Results Using a binary measure of adherence based on salivary varenicline levels, adherence was higher among older, white, and more educated participants. Relative to 3, 7, and 14-day pill count, 12-week pill count was the only significant measure able to discriminate adherence as defined by salivary varenicline levels (assessed by area under the receiver operating characteristic curve; AUC=0.59, p =0.004). Seventy-two percent of participants who indicated adherence on 12-week pill count were classified as adherent based on varenicline saliva levels (sensitivity=0.80; specificity=0.40). There was modest variability in the relationship between 12-week pill count and varenicline levels across race and rate of nicotine metabolism. Lastly, General Estimating Equation models demonstrated that longitudinal changes in withdrawal, craving, negative and positive affect, and side effect count and severity were not related to adherence based on salivary varenicline levels. Conclusions These results indicate that 12-week pill count was the best, albeit a relatively weak, measure of varenicline adherence; additional factors associated with treatment adherence need to be identified.

      Introduction There are higher levels of alcohol misuse in the military compared to the general population. Yet there is a dearth of research in military populations on the longitudinal patterns of alcohol use. This study aims to identify group trajectories of alcohol consumption in the UK military and to identify associations with childhood adversity, deployment history and mental disorder. Methods Data on weekly alcohol consumption across an eight year period and three phases of a UK military cohort study (n=667) were examined using growth mixture modelling. Results Five alcohol trajectory classes were identified: mid-average drinkers (55%), abstainers (4%), low level drinkers (19%), decreasing drinkers (3%) and heavy drinkers (19%). Alcohol consumption remained stable over the three periods in all classes, other than in the small decreasing trajectory class. Individuals in the heavy drinking class were more likely to have deployed to Iraq. Abstainers and heavy drinkers were more likely to report post-traumatic stress disorders at baseline compared to average drinkers. Conclusions Heavy drinkers in the UK military did not change their drinking pattern over a period of eight years. This highlights the need to develop effective preventive programmes to lessen the physical and psychological consequences of long-term heavy alcohol use. Individuals with a mental health problem appeared more likely to either be drinking at a high level or to be abstaining from use.

      Introduction Smoking cessation-related weight gain can have significant negative health and career consequences for military personnel. Alcohol reduction combined with smoking cessation may decrease weight gain and relapse. Method A randomized clinical trial of military beneficiaries compared a standard smoking cessation (i.e., brief informational) intervention (N =159), with a brief motivational smoking cessation intervention that emphasized reduced drinking to lessen caloric intake and minimize weight gain (N =158). Results Participants who received the motivational intervention were significantly more likely to quit smoking at the 3-month follow-up (p =0.02), but the differences were not maintained at 6 (p =0.18) or 12months (p =0.16). Neither weight change nor alcohol reduction distinguished the 2 groups. Smoking cessation rates at 12months (motivational group=32.91%, informational group=25.79%) were comparable to previous studies, but successful cessation was not mediated by reduced drinking. Conclusions Alcohol reduction combined with smoking cessation did not result in decreased weight gain or improved outcomes.

      Introduction Relapse is a common factor within the behavior change process. However, there is scarce and limited knowledge of smoking relapse situations in population-based samples. The aim of this study was to identify smoking relapse situations among a sample of Spanish relapsers from the general population. Methods A sample of 775 relapsers was recruited among the general population using a snowball method. Participants completed a survey including sociodemographic, smoking-related and psychopathology variables. Smoking relapse situations were identified through specific questions assessing different aspects related to the last relapse episode. Results The majority of smoking relapse situations were attributed to positive affect (36.6%) and negative affect (34.3%), followed by lack of control (10.1%), smoking habit (6.7%), craving or nicotine withdrawal (6.3%), and social pressure (5.9%). Being unemployed and having a mental disorder in the past increased the likelihood of relapse in situations of negative affect. Being single and having quit smoking to save money were associated with an increased likelihood of relapse in situations of positive affect. Conclusions Affect plays a significant role in smoking relapse among a community sample of unassisted Spanish smokers. Relapse may be much more of an affective and situational process than a habit, physiological or social pressure. Findings from this study may help develop tailored community smoking relapse prevention strategies or programs.

      Introduction With more states legalizing marijuana use, the marijuana industry has grown, introducing a variety of marijuana products. Our study explores the use of multiple marijuana products (poly-marijuana use) and the characteristics associated with this behavior. Methods Past-month marijuana users aged 18–34years were surveyed online via an existing online panel (n=2444). Participants answered questions about past-month use of three types of marijuana (plant-based, concentrates, edibles), marijuana use patterns, and driving after use. Latent class analysis was used to identify subgroups of marijuana users. Results Four classes of marijuana users were identified: Light plant users, who used only plant-based products infrequently and were unlikely to drive after use (32%); Heavy plant users, who used mainly plant-based products frequently, multiple times per day, and were likely to drive after use (37%); Plant and concentrates users, who used plant-based products heavily and concentrates at least infrequently, used multiple times per day, and were likely to drive after use (20%); Light plant and edibles users, who used both products infrequently and were unlikely to drive after use (10%). Those in legal marijuana states were more likely to belong to the poly-marijuana groups. Discussion Our findings reflect the increase in popularity of new marijuana products in legal states and suggest that heavy user groups, including concentrates users, are associated with driving after use. As various forms of marijuana use increases, monitoring and surveillance of the use of multiple types of marijuana will be important for determining potential varying impacts on physiological and social consequences.

      To develop a consensus on the definition and measurement of Internet gaming disorder (IGD), several recent studies have used the DSM-5's proposed criteria for IGD as the basis in scale construction. This study contributes to this emerging consensus by developing and validating a new Chinese Internet Gaming Disorder Scale (C-IGDS) based on the DSM-5 criteria. A representative sample of Hong Kong community adults (n =502, 50% men, mean age=37.1, age range=18–60) was recruited for a telephone survey with random digit dialing. Various statistical techniques were used to assess the psychometric properties of the C-IGDS. The C-IGDS had good reliability (Cronbach's α=0.91) and structural validity (CFA model fit: RMSEA=0.027, CFI=0.991, TLI=0.988) in our sample. Moderate to moderately strong correlations with depressive symptoms (r =0.617, p<0.001), social anxiety symptoms (r =0.366, p<0.001), and gaming hours (r =0.412, p<0.001) supported the criterion validity of the C-IGDS. In addition, the C-IGDS exhibited strict measurement invariance for sex and at least strong measurement invariance for age. In addition to providing the first Chinese scale for measuring IGD based on the DSM-5′s proposed criteria, this study provides empirical support for the validity of these diagnostic criteria as the basis for a universal measure of IGD. Most important, this study is the first to reveal the criteria's measurement invariance, thereby indicating their suitability for use with diverse demographic groups.

      Background Gambling is relatively under-assessed in Veterans Affairs (VA) substance use disorder (SUD) treatment settings, yet shared characteristics with substance addiction suggest the importance of understanding how gambling behaviors present in Veterans seeking SUD care. Method We evaluated substance use, mental health, and violence-related correlates of past 30-day gambling among 833 Veterans (93% male, M age 48years, 72% Caucasian) seeking treatment in VA outpatient mental health and SUD clinics who completed screening for a randomized clinical trial. Results A total of 288 (35%) Veterans reported past 30-day gambling. Among those who gambled, 79% had cravings/urges to gamble, whereas between 20%–27% of gamblers reported perceived relationship, legal, and daily life problems related to gambling, as well as difficulty controlling gambling. A logistic regression analysis revealed that age, recent binge-drinking, and non-partner physical aggression were associated with recent gambling. Conclusions Gambling was associated with binge-drinking and non-partner physical aggression, supporting potential shared characteristics among these behaviors such as impulsivity and risk-taking, which may complicate SUD treatment engagement and effectiveness. Findings support the need to screen for gambling in the VA, and to adapt treatments to include gambling as a potential behavioral target or relapse trigger, particularly among heavy drinking patients.

      Background Studies show higher lifetime prevalence of suicidality in individuals with pathological gambling. However, less is known about the relationship between pathological gambling and current suicidal ideation. Objectives We investigated socio-demographic, clinical and gambling-related variables associated with suicidality in treatment-seeking individuals. Methods Bivariate analyses and logistic regression models were generated on data from 903 individuals to identify measures associated with aspects of suicidality. Results Forty-six percent of patients reported current suicidal ideation. People with current suicidal thoughts were more likely to report greater problem-gambling severity (p <0.001), depression (p <0.001) and anxiety (p <0.001) compared to those without suicidality. Logistic regression models suggested that past suicidal ideation (p <0.001) and higher anxiety (p <0.05) may be predictive factors of current suicidality. Conclusions Our findings suggest that the severity of anxiety disorder, along with a lifetime history of suicidal ideation, may help to identify treatment-seeking individuals with pathological gambling with a higher risk of suicidality, highlighting the importance of assessing suicidal ideation in clinical settings.

      Background Previous literature suggests that trait impulsivity and engagement in non-drug-related behavioral addictions (e.g., Internet addiction, food addiction) are two risk factors for drug use. Here we further investigated the potential impact of having one or both of these risk factors on drug use in Los Angeles area adolescents. Method High school students (N =1612; Mean age=14.1) completed self-report surveys measuring two potential risk factors (impulsivity, lifetime history of several behavioral addictions), and past 6-month use of tobacco, alcohol and marijuana. Participants who reported never using drugs completed questionnaires assessing their susceptibility for future use. Results In general, adolescents who endorsed either impulsivity alone or at least two behavioral addictions alone were more likely to have used tobacco, alcohol, or marijuana compared to individuals who had neither risk factor (OR=2.50–4.13), and individuals who endorsed both impulsivity and three or more behavioral addictions were the most likely to have used these drugs (OR=9.40–10.13). Similarly, among those who had never tried a drug, individuals with this combined set of risk factors were the most likely to be susceptible to future drug use (OR=3.37–5.04). Discussion These results indicate that the combination of trait impulsivity and a history of behavioral addictions increases the risk for current and future drug use in adolescents, to a greater extent than either risk factor alone. It may be useful for drug prevention efforts to target impulsive adolescents who also actively engage in other non-drug-related addictive behaviors.

      Bronfenbrenner's (1979) ecological model focuses on the interrelation between different contexts and the interaction between individuals and their proximal contexts. Based on this theory, the present study tested a moderated mediation model of family, peer, and individual characteristics to investigate how they impact adolescent Internet addiction. Specifically, we examined whether deviant peer affiliation partially mediated the relation between perceived parental monitoring and adolescent Internet addiction, and whether this indirect relation was moderated by effortful control. A total of 747 Chinese middle school students filled out anonymous questionnaires concerning perceived parental monitoring, deviant peer affiliation, effortful control, and Internet addiction. The findings indicated that while the impact of parental monitoring on Internet addiction was partially mediated by deviant peer affiliation, effortful control moderated the first stage of the indirect relationship. For low effortful control adolescents, perceived parental monitoring negatively predicted deviant peer affiliation. Conversely, the indirect path was not significant for high effortful control adolescents. These findings highlight the need to consider family, peer and individual factors simultaneously when evaluating risks associated with adolescent Internet addiction and have important implications for the prevention and intervention of adolescent Internet addiction.

      Background Internet addiction (IA) is prevalent among adolescents but it is potentially revertible. Only three Taiwan adolescent studies reported IA remission and a few related factors. We investigated incidence and predictors of remission among Hong Kong Chinese secondary school students with a 12-month longitudinal study. Methods IA was defined as Chen Internet Addiction Scale (CIAS) score>63. Validated measures were used to assess students' psychosocial wellbeing at baseline and follow-up. Results Of 1545 students with IA at baseline, 1296 (83.9%) provided matched baseline/12-month follow-up data; their data were analyzed. Incidence of remission (CIAS≤63 at follow-up) was 59.29/100 person-years. Significant predictors included: 1) baseline CIAS score (ORa=.95), 2) baseline health belief model (HBM) constructs [perception of having severe IA (ORa=.34), perceived susceptibility to IA (ORa=0.82), perceived barrier (ORa=0.95), cue to action from parents (ORa=0.82), and self-efficacy for reducing Internet use (ORa=1.13)], and 3) baseline psychosocial health measures [self-esteem (ORa=1.03), severe depression (ORa=0.72) and social anxiety (ORa=0.96)] and their changes over time [depression (ORa=.95), anxiety (ORa=.94), loneliness (ORa=.93), self-esteem (ORa=1.07), positive affect (ORa=1.10) and family support (ORa=1.03)]. Two-thirds (64.3%) of the remission group presented reduced CIAS score>1.5 SD, and recorded larger improvements in psychosocial status over time than the non-remission group. Conclusion Without noticeable interventions, incidence of remission was high and related to improvements in psychosocial health. Most of the HBM constructs, and baseline/changes in psychosocial measures predicted remission. Interventions to increase remission should modify these factors.

      The present study reports a preliminary evaluation of D.A.R.E.'s new elementary school keepin' it REAL substance abuse prevention program. Given the widespread dissemination of D.A.R.E., this evaluation, even though of short term effects, has important implications for national prevention efforts. The new prevention curriculum teaches social and emotional competencies such as decision making and resistance skills. Social and emotional competencies and other risk factors were examined among students (N =943) in 26 classrooms, 13 classrooms in the treatment condition (n =359) and 13 classrooms in the control condition (n =584) using a quasi-experimental matched group design. Pretest comparisons of treatment and control groups were completed, along with attrition analyses, and hierarchical logistic and linear regressions were computed to assess the intervention. The results revealed that the intervention produced significant effects on preventative factors such as the likelihood of resisting peer pressure, increased responsible decision making knowledge and decision-making skills, and confidence in being able to explain why they would refuse offers of cigarettes. The results of this study suggest that D.A.R.E.'s elementary keepin' it REAL program has promise as a social and emotional learning (SEL) based prevention program.

      Parent-adolescent relationship (PAR) factors such as social support and negative interactions are associated with initiation of alcohol and marijuana use during adolescence. However, few studies have examined whether the relationship between PAR, especially the paternal role, and substance use onset varies by ethnicity. This is important given that ethnic group differences have been related to alcohol and marijuana use, cultural values and parenting. This study examines whether ethnicity moderates the prospective prediction of substance use onset by PAR factors. The sample comprised 124 adolescents who self-identified as Hispanic and 795 adolescents who self-identified as non-Hispanic Whites, and was drawn from an ongoing longitudinal survey on adolescent substance use. Discrete-time survival modeling was used to prospectively predict age at onset of substance use among participants who were substance-naïve at baseline. Interactions between ethnicity and PAR factors indicated that PAR factors had a larger influence on age of alcohol and marijuana onset for Hispanics than for Caucasians. Among Hispanics, greater social support from and greater negative interactions with the father-figure were more predictive of earlier onset of alcohol, and greater social support from the mother-figure was more predictive of later alcohol onset, compared to Caucasians. Similarly, greater negative interactions with the father-figure were more predictive of earlier onset of marijuana use among Hispanics than among Caucasians. These findings suggest the influence of PAR on alcohol and marijuana use onset may be larger for Hispanics than for Caucasians. Incorporating these parenting factors in substance use prevention programs advances public health in a culturally sensitive manner that is relevant to at-risk Hispanic adolescents.

      Background Both positive smoking outcome expectancies and metacognitions about smoking have been found to be positively associated with cigarette use and nicotine dependence. The goal of this study was to test a model including nicotine dependence and number of daily cigarettes as dependent variables, anxiety and depression as independent variables, and smoking outcome expectancies and metacognitions about smoking as mediators between the independents and dependents. Methods The sample consisted of 524 self-declared smokers who scored 3 or above on the Fagerstrom Test for Nicotine Dependence (FTND: Uysal et al., 2004). Results Anxiety was not associated with either cigarette use or nicotine dependence but was positively associated with all mediators with the exception of stimulation state enhancement and social facilitation. Depression, on the other hand, was found to be positively associated with nicotine dependence (and very weakly to cigarette use) but was not associated with either smoking outcome expectancies or metacognitions about smoking. Only one smoking outcome expectancy (negative affect reduction) was found to be positively associated with nicotine dependence but not cigarette use. Furthermore one smoking outcome expectancy (negative social impression) was found to be positively associated with cigarette use (but not to nicotine dependence). All metacognitions about smoking were found to be positively associated with nicotine dependence. Moreover, negative metacognitions about uncontrollability were found to be positively associated with cigarette use. Conclusions Metacognitions about smoking appear to be a stronger mediator than smoking outcome expectancies in the relationship between negative affect and cigarette use/nicotine dependence. The implications of these findings are discussed.
