  • Decreasing ADHD phenotypic heterogeneity: searching for neurobiological
           underpinnings of the restrictive inattentive phenotype
    • Abstract: Abstract During the process of developing the DSM-5, a new phenotype of ADHD was proposed—the ADHD restrictive inattentive presentation (ADHD-RI), describing subjects with high endorsement of inattentive symptoms and a low level of hyperactivity. However, this phenotype was not included in the DSM-5 because of the lack of robust neurobiological data. We aimed to assess the specific neurobiological underpinnings of individuals presenting ADHD-RI. We compared a sample of 301 subjects (101 ADHD-Combined; 50 ADHD-RI; 50 ADHD predominantly inattentive type and 100 typically developing subjects) aged 8–15 years, using a complete neuropsychological battery, molecular genetic data (DRD4 and DAT1 most studied polymorphisms) and functional MRI during a Go-No/Go task. Subjects with ADHD-RI had a significantly different neuropsychological profile compared with the other groups, including lower psychomotor speeds, longer reaction times and the worst overall performance in the global neurocognitive index. The proportion of subjects with the presence of DRD4–7 repeat allele was significantly higher in ADHD-RI. The fMRI data suggested that more attention-related posterior brain regions (especially temporo-occipital areas) are activated in ADHD-RI during both Go and No-Go cues compared to TD controls and ADHD predominantly inattentive type. ADHD-RI may represent a different phenotype than other types of ADHD. In addition, our results suggest that reducing the phenotypic heterogeneity may aid in the search for the neurobiological underpinnings of ADHD.

  • Health-related quality of life of children with
           attention-deficit/hyperactivity disorder versus children with diabetes and
           healthy controls
    • Abstract: Abstract The impact of attention-deficit/hyperactivity disorder (ADHD) on health-related quality of life (HRQoL) is reported to be similar to that of other mental health and physical disorders. In this cross-sectional study, we hypothesized that children with ADHD and children with type 1 diabetes mellitus (T1DM) would have significantly worse HRQoL compared with healthy children, and that better clinical status in ADHD and T1DM would be associated with better HRQoL. Children were recruited from three outpatient services in Scotland. Responses to two frequently used validated HRQoL instruments, the Paediatric Quality of Life Inventory (PedsQL) and Child Health and Illness Profile-child edition (CHIP-CE), were obtained from parents/carers and children (6–16 years) with/without ADHD or T1DM. Child and parent/carer-completed HRQoL measurements were evaluated for 213 children with ADHD, 58 children with T1DM and 117 healthy children (control group). Significantly lower self and parent/carer ratings were observed across most PedsQL (P < 0.001) and CHIP-CE (P < 0.05) domains (indicating reduced HRQoL) for the ADHD group compared with the T1DM and control groups. Parent/carer and child ratings were significantly correlated for both measures of HRQoL (PedsQL total score: P < 0.001; CHIP-CE all domains: P < 0.001), but only with low-to-moderate strength. Correlation between ADHD severity and HRQoL was significant with both PedsQL and CHIP-CE for all parent/carer (P < 0.01) and most child (P < 0.05) ratings; more ADHD symptoms were associated with poorer HRQoL. These data demonstrate that ADHD has a significant impact on HRQoL (as observed in both parent/carer and child ratings), which seems to be greater than that for children with T1DM.

  • Emotional face recognition in adolescent suicide attempters and
           adolescents engaging in non-suicidal self-injury
    • Abstract: Abstract Little is known about the bio-behavioral mechanisms underlying and differentiating suicide attempts from non-suicidal self-injury (NSSI) in adolescents. Adolescents who attempt suicide or engage in NSSI often report significant interpersonal and social difficulties. Emotional face recognition ability is a fundamental skill required for successful social interactions, and deficits in this ability may provide insight into the unique brain–behavior interactions underlying suicide attempts versus NSSI in adolescents. Therefore, we examined emotional face recognition ability among three mutually exclusive groups: (1) inpatient adolescents who attempted suicide (SA, n = 30); (2) inpatient adolescents engaged in NSSI (NSSI, n = 30); and (3) typically developing controls (TDC, n = 30) without psychiatric illness. Participants included adolescents aged 13–17 years, matched on age, gender and full-scale IQ. Emotional face recognition was evaluated using the diagnostic assessment of nonverbal accuracy (DANVA-2). Compared to TDC youth, adolescents with NSSI made more errors on child fearful and adult sad face recognition while controlling for psychopathology and medication status (ps < 0.05). No differences were found on emotional face recognition between NSSI and SA groups. Secondary analyses showed that compared to inpatients without major depression, those with major depression made fewer errors on adult sad face recognition even when controlling for group status (p < 0.05). Further, compared to inpatients without generalized anxiety, those with generalized anxiety made fewer recognition errors on adult happy faces even when controlling for group status (p < 0.05). Adolescent inpatients engaged in NSSI showed greater deficits in emotional face recognition than TDC, but not inpatient adolescents who attempted suicide. Further results suggest the importance of psychopathology in emotional face recognition. Replication of these preliminary results and examination of the role of context-dependent emotional processing are needed moving forward.

  • New evidence of factor structure and measurement invariance of the SDQ
           across five European nations
    • Abstract: Abstract The main purpose of the present study was to analyse the internal structure and to test the measurement invariance of the Strengths and Difficulties Questionnaire (SDQ), self-reported version, in five European countries. The sample consisted of 3012 adolescents aged between 12 and 17 years (M = 14.20; SD = 0.83). The five-factor model (with correlated errors added), and the five-factor model (with correlated errors added) with the reverse-worded items allowed to cross-load on the Prosocial subscale, displayed adequate goodness of-fit indices. Multi-group confirmatory factor analysis showed that the five-factor model (with correlated errors added) had partial strong measurement invariance by countries. A total of 11 of the 25 items were non-invariant across samples. The level of internal consistency of the Total difficulties score was 0.84, ranging between 0.69 and 0.78 for the SDQ subscales. The findings indicate that the SDQ’s subscales need to be modified in various ways for screening emotional and behavioural problems in the five European countries that were analysed.

  • A comprehensive scoping review of ability and disability in ADHD using the
           International Classification of Functioning, Disability and
           Health-Children and Youth Version (ICF-CY)
    • Abstract: Abstract This is the first in a series of four empirical investigations to develop International Classification of Functioning, Disability and Health (ICF) Core Sets for Attention Deficit Hyperactivity Disorder (ADHD). The objective here was to use a comprehensive scoping review approach to identify the concepts of functional ability and disability used in the scientific ADHD literature and link these to the nomenclature of the ICF-CY. Systematic searches were conducted using Medline/PubMed, PsycINFO, ERIC and Cinahl, to extract the relevant concepts of functional ability and disability from the identified outcome studies of ADHD. These concepts were then linked to ICF-CY by two independent researchers using a standardized linking procedure. Data from identified studies were analysed until saturation of ICF-CY categories was reached. Eighty studies were included in the final analysis. Concepts contained in these studies were linked to 128 ICF-CY categories. Of these categories, 68 were considered to be particularly relevant to ADHD (i.e., identified in at least 5 % of the studies). Of these, 32 were related to Activities and participation, 31 were related to Body functions, and five were related to environmental factors. The five most frequently identified categories were school education (53 %), energy and drive functions (50 %), psychomotor functions (50 %), attention functions (49 %), and emotional functions (45 %). The broad variety of ICF-CY categories identified in this study underlines the necessity to consider ability and disability in ADHD across all dimensions of life, for which the ICF-CY provides a valuable and universally applicable framework. These results, in combination with three additional preparatory studies (expert survey, focus groups, clinical study), will provide a scientific basis to define the ICF Core Sets for ADHD for multi-purpose use in basic and applied research, and every day clinical practice.

  • Early response or nonresponse at week 2 and week 3 predict ultimate
           response or nonresponse in adolescents with schizophrenia treated with
           olanzapine: results from a 6-week randomized, placebo-controlled trial
    • Abstract: Abstract In adults with schizophrenia, early response/non-response (ER/ENR) to antipsychotics at 2 weeks robustly predicts ultimate response/non-response (UR/UNR). However, less data about the predictive value of ER/ENR exist in adolescents with schizophrenia. Post hoc analysis of a 6-week trial in adolescents aged 13–17 with schizophrenia were randomized 2:1 to olanzapine or placebo. ER was defined as ≥20 % reduction in Brief Psychiatric Rating Scale-children (BPRS-C) total score at week 2 (ER2) or 3 (ER3); UR was defined with increasing stringency as total BPRS-C score reduction ≥20, ≥30, ≥40 or ≥50 %; remission was defined cross-sectionally using Andreasen et al. (2005) criteria. By week 2 (n = 69) and 3 (n = 66), olanzapine-treated youth achieved 73.3 and 85.5 % of their overall BPRS-C score reduction at 6 weeks last observation carried forward. ER and ENR patients did not differ significantly regarding baseline demographic, illness and treatment variables. ER 2 (frequency = 68.1 %) and ER 3 (frequency = 65.2 %) significantly predicted UR and remission (p = 0.0044–p < 0.0001), with ER3 having more predictive power. A ≥ 20 % BPRS-C reduction threshold for ER had best predictive validity (area under the curve = 0.88–0.92). At 6 weeks, patients with ER had significantly greater improvements in BPRS-C, Clinical Global Impressions Improvement and Severity scores, greater cross-sectional remission and less all-cause discontinuation (p = 0.047–p < 0.0001). Adverse event profiles were similar in the ER and ENR groups. Adolescents with schizophrenia experienced the majority of symptomatic improvement early during olanzapine treatment. ER predicted UR and remission, with ER3 having best predictive power. A ≥ 20 % improvement threshold for defining ER was confirmed as a robust outcome indicator.

  • Modelling trajectories of psychosomatic health complaints in children and
           adolescents: results of the BELLA study
    • Abstract: Abstract Psychosomatic health complaints (PHC) can significantly impair psychosocial development of children and adolescents and are therefore of considerable interest in health sciences and public health surveillance. Questions addressed the type of function that describes individual trajectories best, potential differences between these, and corresponding predictors from the perspective of both children and their parents. Based on the German population-based and representative BELLA cohort sample, 2,857 children and adolescents between 7 and 17 years of age at baseline were analysed over a period of 3 years with yearly follow-ups using mixed growth curve analyses. PHC were measured in accordance with the health behaviour in school-aged children-symptom checklist. The mean level of PHC was rather low, slightly lower for the parent report than for the self-report and significantly different between subjects. Concerning the parent report, the 2-year course is best described by a slowly increasing linear trend that decelerates somewhat over time. The increasing linear trend was more pronounced in the self-report from 11 to 17 years of age, but was significantly different for each subject and correlated with baseline scores. Trajectories could be explained by known predictors, most importantly by mental health problems of the child or adolescent. The results confirm the findings of previous studies and provide representative data about the individual short-term development of PHC in children and adolescents in Germany.

  • Eating disorder symptoms do not just disappear: the implications of
           adolescent eating-disordered behaviour for body weight and mental health
           in young adulthood
    • Abstract: Abstract This study reports the outcomes of childhood and adolescent eating-disordered behaviour on the development of body mass index (BMI) and psychological functioning in young adulthood in a population-based sample in Germany (the BELLA study). Information at baseline and follow-up was obtained through a telephone interview and mailed self-report questionnaires. At both measurement points, BMI, eating disorder symptoms (SCOFF questionnaire), and symptoms of depression and anxiety were assessed in the same cohort of 771 participants (n = 420 females, n = 351 males). The age range at baseline was 11–17 years, and the age range at follow-up was 17–23 years. High scores for eating-disordered behaviour in childhood or adolescence significantly predicted eating-disordered behaviour in young adulthood (multiplicative effect estimate: 1.31; 95 % CI: 1.2–1.42, p < 0.0001), although there was a decline in prevalence (from 19.3 to 13.8 %, p = 0.002) and severity (mean decrease in SCOFF 0.07, 95 % CI: −0.01–0.14, p = 0.06). After accounting for potentially confounding variables at baseline (SES, probands’ BMI, parental BMI, depressive symptoms), participants with more eating disorder symptoms at baseline had a higher risk of developing overweight (odds ratio (OR): 1.58; 95 % CI: 1.19–2.09, p = 0.001), obesity (OR = 1.67; 95 % CI: 1.03–2.66, p = 0.03), and depressive symptoms at follow-up (additive effect estimate: 0.45; 95 %CI: 0.19–0.7, p = 0.0006). Early symptoms of depression showed a significant relationship with extreme underweight in young adulthood (OR = 1.13; 95 %CI: 1.01–1.25, p = 0.02). The high stability of eating disorder symptoms and the significant association with overweight and worse mental health in adulthood underscore the need for early detection and intervention during childhood and adolescence. Youth with depression should be monitored for the development of restrictive eating disorders.

  • Risk and protective factors for the development of depressive symptoms in
           children and adolescents: results of the longitudinal BELLA study
    • Abstract: Abstract Mental health problems in children and adolescents are frequent, with a high risk of persistence into adulthood. Therefore, the investigation of determinants of onset and course of mental health problems is of high importance. The present paper investigates the impact of protective and risk factors on the development of depressive symptoms in children and adolescents. The BELLA study is the mental health module of the German National Health Interview and Examination Survey for children and adolescents (KIGGS). Based on the first three measurement points of the BELLA study (covering a period of 2 years), the present analysis focused on children and adolescents aged 11–17 years at baseline (n = 1,643; 50.6 % female). A longitudinal growth modelling approach was used. Mental health problems in parents (parent-reports) predicted depressive symptoms in children and adolescents (self-reports) as well as the development of these symptoms over time. Further, child-reported protective factors of self-efficacy, positive family climate and social support were associated with less depressive symptoms at baseline. Additionally, positive changes in protective factors were associated with the development of less depressive symptoms over time. Finally, family climate and social support moderated the detrimental influence of parental psychopathology on child’s depressive symptoms. The addressed determinants for the development of depressive symptoms in children and adolescents are highly relevant for prevention and intervention strategies. Future research should investigate specific risk and protective factors focusing in detail on further mental health disorders and their development in children and adolescents.

  • Six years ahead: a longitudinal analysis regarding course and predictive
           value of the Strengths and Difficulties Questionnaire (SDQ) in children
           and adolescents
    • Abstract: Background Scientifically sound and valid information concerning course and prediction of mental health problems in children and adolescents in the general population is scarce, although needed for public mental health issues and daily clinical practice. Objectives The psychopathological profiles of children and adolescents were analysed using the parent version of the Strengths and Difficulties Questionnaire (SDQ-P) in a longitudinal setting, also investigating the predictive value of the SDQ-scores. Methods SDQ’s total psychopathological difficulties, emotional symptoms and hyperactivity-inattention scores of n = 630 children and adolescents (age 6–18;11 years) were examined along four assessment measurement points (T0–T3) over 6 years, using data from the BELLA study. According to the English normative data, the participants were categorized as “normal”, “borderline” or “abnormal” based on their SDQ-scores. Groups remaining within categories were descriptively determined by means of frequency analysis, a subsequent graphical evaluation displayed the transitions from T0 to T3 concerning the different categorical classifications. Finally, ordered probit regression was used to examine whether age, gender, socio-economic status (SES) and baseline impact-score (IS) correspond to the SDQ-predicted classification. Results As expected, low SES and high SDQ-IS were associated with significantly increased scores on all examined SDQ-scales. Regarding the long-term aspect of SDQ-scores it could be shown that most children and adolescents remained “normal” over a measurement period of 6 years, while only a small number of children and adolescents steadily remained “abnormal” or newly developed mental health problems, respectively. For example, on the “hyperactivity-inattention”-scale, only 1 % of the children and adolescents changed from “normal” to “abnormal” (T0–T3), whereas on the “emotional symptoms”-scale, 7 % changed from “normal” to “abnormal” (T0–T3). In general, the SDQ-category “borderline” and specifically the subscale “emotional symptoms” change in both directions. Abnormal SDQ-scores at baseline, SES, gender and IS were related to the prediction of the SDQ-sores at T3. Conclusion An SDQ-screening of children and adolescents may help for early detection, prediction and treatment planning. Also, these results may contribute to a better understanding of the course of mental health problems in childhood and concurrently may allow a better psychoeducation and prevention.

  • Recent international trends in psychotropic medication prescriptions for
           children and adolescents
    • Abstract: Abstract Prescriptions of psychotropic medications have become an important intervention for many children and adolescents with mental disorders, and the rise of these prescriptions is debated intensively both among experts and the public. This review reports some recent international findings on point prevalence rates, cross-country comparisons, and time trends in psychotropic medication prescriptions for children and adolescents. Besides the total prescription rates, figures for antidepressants, antipsychotics, stimulants, and anxiolytics prescriptions are provided. The overall prescription rates of psychotropics in general and the major medication subgroups prescribed to children and adolescents vary substantially between countries with the US consumption being markedly higher than the use in European countries. However, even among the latter there are marked variations in findings. Studies reporting on time trends clearly indicate that there was a marked increase in the use of psychotropics for children and adolescents in the recent past. However, only a single study adjusted prevalence rates for the increasing number of children and adolescents assessed and treated in institutions providing mental health care. Considering the increasing numbers of children and adolescents seen in psychiatric services, the increase of psychotropic medications is less strong though still pronounced enough to stimulate further reflections on the use of these interventions.

  • Long-term course of ADHD symptoms from childhood to early adulthood in a
           community sample
    • Abstract: Abstract Comparatively little information is available from population-based studies on subgroup trajectories of attention-deficit/hyperactivity disorder (ADHD) core symptoms of inattention and hyperactivity-impulsivity (particularly as defined by DSM-IV and ICD-10). Recent report of a subgroup with high and increasing inattention symptoms across development requires replication. To identify the different trajectory subgroups for inattention, hyperactivity-impulsivity and total symptoms of ADHD in children and adolescents aged 7–19 years. Eleven birth cohorts from 2,593 families with children and adolescents who had parent ratings for the outcome measures of inattention, hyperactivity-impulsivity or total symptoms were considered. Data were analysed using an accelerated longitudinal design and growth mixture modelling was applied to detect subgroups. For all three outcome measures, three trajectories with low (78.3–83.3 %), moderate (13.4–18.8 %) and high (2.8–3.2 %) symptom levels were detected. Course within these subgroups was largely comparable across outcome domains. In general, a decrease in symptoms with age was observed in all severity subgroups, although the developmental course was stable for the high subgroups of inattention and total symptoms. About 3 % of children in a community-based sample follow a course with a high level of ADHD symptoms. In this high trajectory group, hyperactivity-impulsivity symptoms decrease with age from 7 to 19 years, whilst inattention and total symptoms are stable. There was no evidence for an increase in symptoms across childhood/adolescence in any of the severity groups.

  • Mental health care use among children and adolescents in Germany: results
           of the longitudinal BELLA study
    • Abstract: Abstract Data on mental health care use of children and adolescents in Germany is scarce. This study investigates the degree of mental health care use, its trajectories and influencing factors among children and adolescents in Germany, using longitudinal data of the BELLA study. The BELLA study is the mental health module of the representative German National Health Interview and Examination Survey for children and adolescents (KiGGS). Baseline data of N = 2,863 participants aged 7–17 years were collected between 2003 and 2006. The study sample was followed up in three additional measurement points, assessing general mental health problems and impairment, specific mental health problems, and mental health care use. In the current study, we analysed data from the first three measurement points. At baseline, 5.9 % of all participants used mental health care in the past 12 months. Among those with general mental health problems, 29.5 % sought professional help. Only a minority of participants reporting mental health care use at baseline also sought help at the following two measurement points. Analysing a random intercept only model, mental health care use was found to be more likely among participants living in larger communities as well as in the Eastern part of Germany, among those participants with impairment of mental health problems, and signs of externalizing problems. Our results indicate a temporary character of mental health care use. Participants’ impairment was identified to be the strongest predictor of mental health care use.

  • A longitudinal perspective on childhood adversities and onset risk of
           various psychiatric disorders
    • Abstract: Abstract It is well-known that childhood adversities can have long-term effects on mental health, but a lot remains to be learned about the risk they bring about for a first onset of various psychiatric disorders, and how this risk develops over time. In the present study, which was based on a Dutch longitudinal population survey of adolescents TRAILS (N = 1,584), we investigated whether and how childhood adversities, as assessed with three different measures, affected the risk of developing an incident depressive, anxiety, or disruptive behavior in childhood and adolescence. In addition, we tested gender differences in any of the effects under study. The results indicated that depressive, anxiety and disruptive behavior disorders each had their own, characteristic, pattern of associations with childhood adversities across childhood and adolescence, which was maintained after adjustment for comorbid disorders. For depressive disorders, the overall pattern suggested a high excess risk of incidence during childhood, which decreased during adolescence. Anxiety disorders were characterized by a moderately increased incident risk during childhood, which remained approximately stable over time. Disruptive behavior disorders took an intermediate position. Of the three childhood adversities tested, an overall rating of the stressfulness of the childhood appeared to predict onset of psychiatric disorders best. To conclude, the risk of developing a psychiatric disorder after exposure to adversities early in life depends on the nature of the adversities, the nature of the outcome, and the time that has passed since the adversities without disorder onset.

  • Epidemiology of child psychopathology: major milestones
    • Abstract: Abstract Child psychiatric epidemiology has developed rapidly from descriptive, cross-sectional studies in the 1960s to the current large-scale prospective cohorts that unravel aetiological mechanisms. The objective of the study was to give an overview of epidemiological studies that have influenced child psychiatry. A chronological overview of selected major milestone studies was obtained to demonstrate the development of child psychiatric epidemiology, with a more in-depth discussion of findings and methodological issues exemplified in one cohort, the Generation R Study. Epidemiological studies have been successful in describing the frequency and course of child psychiatric problems. The high expectations that biological factors can be used to better explain, diagnose or predict child psychiatric problems have not been met. More ambitious large-scale child psychiatric cohort studies are needed, carefully applying genetics, neuroscience or other molecular research to better understand how the brain produces maladaptive behaviour. Progress will only be attained if the basic sciences are systematically integrated in cohorts with rigorous epidemiological designs rather than hurriedly inserted in child psychiatric studies.

  • The longitudinal BELLA study: design, methods and first results on the
           course of mental health problems
    • Abstract: Abstract The high prevalence of mental health problems (MHP) in childhood and adolescence is a global health challenge of the 21st century. Information about age of onset, persistence and development of MHP in young people is necessary to implement effective prevention and intervention strategies. We describe the design and methods of the longitudinal BELLA study, which investigates developmental trajectories of MHP from childhood into adulthood, their determinants, and the utilisation of mental health services. First results on the developmental course of MHP in children and adolescents are reported over a 6-year period. The BELLA study is the mental health module of the German National Health Interview and Examination Survey for children and adolescents (KiGGS). BELLA examines the mental health and well-being of children and adolescents aged 7–17 years (a representative subsample of KiGGS, n = 2,863 at baseline). Standardised screening measures served to identify MHP at baseline and at follow-ups (1, 2, and 6 years later). Among children and adolescents participating at all measurement points (n = 1,255), 10 % showed clinically significant MHP at baseline (n = 130). Over the 6-year period, 74.3 % showed no signs of MHP (n = 933), 15.5 % had remitted (n = 194), 2.9 % showed persistent (n = 36) and 7.3 % acute or recurrent MHP (n = 92). Overall, MHP were more likely to occur between the age of 7 and 12 and after the age of 19 years. Regarding mental health service use, 33 % of the participants with acute or recurrent MHP (n = 30) and 63.9 % with persistent MHP used mental health services (n = 23). Mental health problems in children and adolescents have a high risk to persist into adulthood. In children and adolescents a low rate of mental health service use was observed, even among those with mental health problems.
