- The Effects of Mindfulness-Based Cognitive Therapy on Depression and
Anxiety in Women with Premenstrual Syndrome
Abstract: Objective. Little research has been done regarding the role of psychotherapy in the treatment of Premenstrual Syndrome (PMS). The aim of this study was to examine the effect of mindfulness-based cognitive therapy (MBCT) on the PMS symptoms and depression and anxiety symptoms in women with PMS. Design. In a randomized controlled trial, a total of 60 students at Mazandaran University with mild to moderate PMS who had depressive symptoms (Beck depression scores 16–47) were randomly allocated to either an experimental () or a control () group. The experimental group received MBCT in eight group sessions (120 min each) over 8 weeks. The control group received no intervention. All participants completed the Premenstrual Assessment Scale (PAS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) at the beginning and the end of the study. Repeated-measure ANOVA was used to analyze the data. Results. At the end of study, the experimental and control groups showed the following scores, respectively (mean ± SD): depression, and ; anxiety, and ; and total PAS, and . MBCT improved depression and anxiety symptoms and total PAS score. Conclusion. MBCT intervention is acceptable and potentially beneficial in women with PMS symptoms. Psychotherapy should be considered as a treatment option for mild to moderate PMS in women with depressive symptoms.

- The Connections of Pregnancy-, Delivery-, and Infant-Related Risk Factors
and Negative Life Events on Postpartum Depression and Their Role in First
and Recurrent Depression
Abstract: Introduction. The aim of this study is to assess how negative life events and adverse experiences with pregnancy, delivery, the infant(s), and breastfeeding cessation impact on postpartum depression (PPD), specifically in first lifetime and recurrent depression. Method. The study group comprised 104 mothers with a current episode of PPD and a control group of 104 mothers who did not have current PPD. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) was used for data collection. The course of the depression, adverse experiences, and breastfeeding were assessed by self-reports. Results. In age-adjusted multivariate analyses, mental and physical problems during pregnancy or delivery, postpartum problems with the infant and breastfeeding cessation, and negative life events during the previous 12 months were associated with postpartum depression. Eighteen percent (18%) of the mothers had first depression and 82% recurrent depression. Mental and physical problems during pregnancy or delivery were associated with both first lifetime and recurrent depression. Nevertheless, negative life events and infant/breastfeeding issues associated only with recurrent depression. Conclusion. Factors associated with pregnancy and delivery have an impact on PPD, but in recurrent depression other postnatal and psychosocial factors are also important risk factors.

- Suicidal Ideation, Attempt, and Determining Factors among HIV/AIDS
Abstract: Background. Suicide is a serious cause of mortality worldwide and is considered as a psychiatric emergency. Suicide is more frequent in peoples living with HIV/AIDS than in general population. Objective. To assess the proportion and determining factors of suicidal ideation and attempt among peoples living with HIV/AIDS in Ethiopia. Methods. Institutional based cross-sectional study was conducted from May to June 2015 by selecting 393 participants using systematic random sampling technique. Suicide manual of Composite International Diagnostic Interview (CIDI) was used to collect data. Logistic regression was carried out and odds ratio with 95% confidence intervals was computed. Results. The proportion of suicidal ideation and attempt was 33.6% and 20.1%, respectively. Female sex (AOR = 2.6, 95%CI: 1.27–5.22), marital status (AOR = 13.5, 95%CI: 4.69–39.13), depression (AOR = 17.0, 95%CI: 8.76–33.26), CD4 level (AOR = 2.57, 95%CI: 1.34–4.90), and presence of opportunistic infection (AOR = 5.23, 95%CI: 2.51–10.88) were associated with suicidal ideation, whereas marital status (AOR = 8.44, 95%CI: 3.117–22.84), perceived HIV stigma (AOR = 2.9, 95%CI: 1.45–5.99), opportunistic infection (AOR = 2.37, 95%CI: 1.18–4.76), and poor social support (AOR = 2.9, 95%CI: 1.58–5.41) were significantly associated with suicidal attempt. Conclusion. Suicidal ideation and attempt were high among HIV positive patients. Therefore early screening, treatment, and referral of suicidal patients are necessary in HIV clinics.

- Depressive Symptoms among Latino Sexual Minority Men and Latina
Transgender Women in a New Settlement State: The Role of Perceived
Abstract: Background. Little is known about the role of discrimination on depression among Latino sexual and gender identity minorities. This manuscript examined the relationship between ethnic/racial discrimination and sexual discrimination on clinically significant depressive symptoms among Latino sexual minority men (i.e., gay and bisexual men and other men who have sex with men) and Latina transgender women. Methods. A community-based participatory research partnership recruited participants ( = 186; 80.6% cisgender men) in North Carolina to a social network-based HIV intervention. Using baseline data, we quantified the amount of perceived discrimination and conducted mixed-effects logistic regression analyses to examine correlates of clinically significant depressive symptoms. Results. A high percentage of participants reported ethnic/racial discrimination (73.7%) and sexual discrimination (53.8%). In the multivariable models, ethnic/racial discrimination, sexual discrimination, masculinity, fatalism, and social support were significantly associated with clinically significant depressive symptoms. Discussion. Improving mental health requires multilevel interventions that address pertinent individual, interpersonal, and system level factors.

- Prevalence of Antenatal Depression and Associated Risk Factors among
Pregnant Women Attending Antenatal Clinics in Abeokuta North Local
Government Area, Nigeria
Abstract: Objective. The prevalence of antenatal depression (AD) and associated risk factors among pregnant women attending antenatal clinics in Abeokuta North Local Government Area, Nigeria, was determined. Methods. A descriptive cross-sectional survey was conducted, interviewing 314 pregnant women selected by multistage sampling technique from among those attending antenatal clinics. Information was collected using structured questionnaire and a screening tool, Edinburgh Postnatal Depression Scale (EPDS), to assess probable depression. Results. The prevalence of antenatal depression was 24.5%. There were significant associations between antenatal depression and attending public health facility (), young maternal age (), single marital status (), not having formal education (), large family size (), planned pregnancy (), coexisting medical conditions (), history of previous caesarian section (), drinking alcohol during pregnancy (), and gender based abuse (). On health seeking behaviour for antenatal depression among depressed pregnant women, most, 68.9%, consulted their husbands about their symptoms; 57.3% took the decision to get treatment from doctors, and 52% sought prayer in the church. Conclusion. Antenatal depression is prevalent in this study population. Interventions to address its risk factors should be carried out and physicians should suspect depression in pregnant women reporting alcohol use and gender abuse.

- Invisible Victims: Delayed Onset Depression among Adults with Same-Sex
Abstract: The relationship of elevated depression risk recently discovered among adult persons raised by same-sex parents with possible precipitating conditions in childhood has not previously been acknowledged. This study tests whether such inattention is supportable. Logistic regression based risk ratios were estimated from longitudinal measures of mental health outcomes observed in three waves (at ages 15, 22, and 28) of the US National Survey of Adolescent to Adult Health (,701). At age 28, the adults raised by same-sex parents were at over twice the risk of depression (CES-D: risk ratio 2.6, 95% CI 1.4–4.6) as persons raised by man-woman parents. These findings should be interpreted with caution. Elevated risk was associated with imbalanced parental closeness and parental child abuse in family of origin; depression, suicidality, and anxiety at age 15; and stigma and obesity. More research and policy attention to potentially problematic conditions for children with same-sex parents appears warranted.

- Breastfeeding and Postpartum Depression: An Overview and Methodological
Recommendations for Future Research
Abstract: Emerging research suggests that a relationship exists between breastfeeding and postpartum depression; however, the direction and precise nature of this relationship are not yet clear. The purpose of this paper is to provide an overview of the relationship between breastfeeding and postpartum depression as it has been examined in the empirical literature. Also, the potential mechanisms of action that have been implicated in this relationship are also explored. PubMed and PsycINFO were searched using the keywords: breastfeeding with postpartum depression, perinatal depression, postnatal depression. Results of this search showed that researchers have examined this relationship in diverse ways using diverse methodology. In particular, researchers have examined the relationships between postpartum depression and breastfeeding intention, initiation, duration, and dose. Due to a number of methodological differences among past studies we make some recommendations for future research that will better facilitate an integration of findings. Future research should (1) use standardized assessment protocols; (2) confirm diagnosis through established clinical interview when possible; (3) provide a clear operationalized definition for breastfeeding variables; (4) clearly define the postpartum period interval assessed and time frame for onset of symptoms; (5) be prospective or longitudinal in nature; and (6) take into consideration other potential risk factors identified in the empirical literature.

- Prevalence and Severity of Depression and Its Association with Substance
Use in Jimma Town, Southwest Ethiopia
Abstract: Background. Depression is a significant contributor to the global burden of disease and affects 350 million people worldwide. Substance use could be the risk factor for depression. Objective. We aim to determine the prevalence and severity of depression and its association with substance use. Methods. A cross-sectional study was conducted on a sample of 650 respondents in Jimma town in March 2014. A multistage stratified sampling method was conducted. Structured questionnaire and Beck’s Depression Inventory (BDI-II) scale were used for data collection. Data analysis was done using the SPSS Version 20.0 for Windows. Results. The participation rate of respondents was 590/650 (90.77%). The proportion of females was 300 (50.9%). The current prevalence of depression was 171 (29.0%). Based on the BDI-II grading of the severity of depression, 102 (59.6%) had mild, 56 (32.7%) had moderate, 13 (7.6%) had severe depression. In the present study, age of 55 years and above [OR = 5.94, CI: 2.26–15.58], being widowed [OR = 5.18, CI: 1.18–22.76], illiterates [OR = 9.06, CI: 2.96–27.75], khat chewing [OR = 10.07, CI: 5.57–18.25], cigarette smoking [OR = 3.15, CI: 1.51–6.58], and shisha usage [OR = 3.04, CI: 1.01–9.19] were significantly and independently associated with depression. Conclusion. The finding depicted that depression was a moderate public health problem. Advanced age, being widowed, illiterate, khat chewing, and cigarette and shisha smocking could be the potential risk factors for depression. Risk reduction is recommended.

- Psychometric Limitations of the Center for Epidemiologic
Studies-Depression Scale for Assessing Depressive Symptoms among Adults
with HIV/AIDS: A Rasch Analysis
Abstract: The Center for Epidemiological Studies-Depression (CES-D) scale is a widely used measure of depressive symptoms, but its psychometric properties have not been adequately evaluated among adults with HIV/AIDS. This study used an item response theory approach (Rasch analysis) to evaluate the CES-D’s validity and reliability in relation to key demographic and clinical variables in adults with HIV/AIDS. A convenience sample of 347 adults with HIV/AIDS (231 males, 93 females, and 23 transgenders; age range 22–77 years) completed the CES-D. A Rasch model application was used to analyze the CES-D’s rating scale functioning, internal scale validity, person-response validity, person-separation validity, internal consistency, differential item functioning (DIF), and differential test functioning. CES-D scores were generally high and associated with several demographic and clinical variables. The CES-D distinguished 3 distinct levels of depression and had acceptable internal consistency but lacked unidimensionality, five items demonstrated poor fit to the model, 15% of the respondents demonstrated poor fit, and eight items demonstrated DIF related to gender, race, or AIDS diagnosis. Removal of misfitting items resulted in minimal improvement in the CES-D’s substantive and structural validity. CES-D scores should be interpreted with caution in adults with HIV/AIDS, particularly when comparing scores across gender and racial groups.

- A Possible Role of Anhedonia as Common Substrate for Depression and
Abstract: Depression and anxiety are often comorbid, in up to 70% of cases, and the level of one or the other may fluctuate, leading now to a diagnosis of depression, now to a diagnosis of anxiety. For these reasons, and for the presence of many other common factors, it has been suggested that both are part of the same continuum of problems and that they have a common substrate. This paper proposes the possibility that anhedonia may be an important component of this possible common substrate, and it tries to identify the mechanism with which anhedonia could contribute to causing both depression and anxiety. It also proposes an explanation why an intense pleasure could improve both depression and anxiety.

- Symptom Endorsement and Sociodemographic Correlates of Postnatal Distress
in Three Low Income Countries
Abstract: Background. Maternal mental illness has been implicated in adverse child development outcomes. Factors such as context and culture may influence experiences of maternal distress and explain differences in outcomes across settings. Methods. We analyzed baseline data from 5,647 mothers in Ethiopia, India (Andhra Pradesh), and Vietnam participating in an ongoing cohort study (Young Lives) to compare symptom endorsement and sociodemographic correlates of distress. Maternal distress was assessed using the Self-Reporting Questionnaire-20 Items (cutoff: ≥8). Logistic regressions were stratified by sample to identify correlates of distress. Results. Symptom endorsement was similar among distressed women, particularly with regard to feeling unhappy (76%, 80%, and 79%). Notable differences were observed in three items assessing Depressive Thoughts, which were most highly endorsed in Ethiopia (49%–56%). Having a child experiencing a life-threatening event was correlated with distress in all three samples. A variety of correlates were unique to only one sample. Conclusions. There were multiple similarities but also notable differences across sites in the expression and correlates of maternal distress. Feeling unhappy appears to be a hallmark feature of distress. Correlates highlight the relationship between distress and indicators of poverty, child wellbeing, and economic shocks. Differences demonstrate the value of further exploration of cross-cultural differences.

- Efficacy of Electroconvulsive Therapy in Bipolar Disorder with Mixed
Abstract: Introduction. Mixed states represent a frequent presentation of bipolar disorder, associated with higher resistance to psychopharmacology. Limited evidence supports the use of ECT in these patients. We aim to report our experience on treating bipolar mixed states with ECT. Methods. Retrospective data were collected from all bipolar patients submitted to acute ECT treatment, between June 2006 and June 2011. Three groups were created in terms of affective polarity of the episode. CGI rating was used to establish clinical remission and demographic and clinical variables were compared among groups. Long-term outcome was assessed through readmission measures, considering the use of continuation or maintenance ECT. Results. During the study time frame, a total of 50 ECT course treatments were performed on 41 bipolar patients. All affective episodes, except one mixed state, showed a positive clinical response. Patients with mixed state presentation tended to be younger and have an earlier first hospitalization than depressed patients. No differences were found in terms of ECT sessions performed, length of hospital admission, referral to continuation ECT treatment, number of readmissions, and time until next readmission. Conclusions. Our results support the effectiveness of ECT in patients experiencing a mixed affective state.

- Perinatal Depression and Patterns of Attachment: A Critical Risk
Abstract: Background. This study aims to verify if the presence and severity of perinatal depression are related to any particular pattern of attachment. Methods. The study started with a screening of a sample of 453 women in their third trimester of pregnancy, who were administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Experience in Close Relationship (ECR). A clinical group of subjects with perinatal depression (PND, 89 subjects) was selected and compared with a control group (C), regarding psychopathological variables and attachment patterns. Results. The ECR showed a prevalence of “Fearful-Avoidant” attachment style in PND group (29.2% versus 1.1%, ); additionally, the EPDS average score increases with the increasing of ECR dimensions (Avoidance and Anxiety). Conclusion. The severity of depression increases proportionally to attachment disorganization; therefore, we consider attachment as both an important risk factor as well as a focus for early psychotherapeutic intervention.

- Illness Attitudes Associated with Seasonal Depressive Symptoms: An
Examination Using a Newly Developed Implicit Measure
Abstract: The Dual Vulnerability Model of seasonal depression posits that seasonal vegetative symptoms are due to a physiological vulnerability, but cognitive and mood symptoms are the result of negative appraisal of vegetative changes. In addition, rumination may be associated with stronger negative attitudes toward vegetative symptoms. This is the first study to examine implicit attitudes toward vegetative symptoms. We hypothesized that illness attitudes about fatigue moderate the relationship between the severity of vegetative symptoms and the severity of cognitive symptoms and that the illness attitudes are associated with rumination. This study also developed an implicit method to assess the appraisal of fatigue as indicating illness. Results supported both hypotheses. Illness attitudes toward fatigue moderated the relationship between vegetative symptoms and cognitive symptoms. Ruminative response style was positively associated with implicit illness attitudes towards fatigue. The study provides support for the role of negative appraisals of vegetative symptoms in the development of cognitive and mood seasonal depressive symptoms.

- Cognitive Mechanisms Reciprocally Transmit Vulnerability between
Depressive and Somatic Symptoms
Abstract: Despite high comorbidity between depressive and somatic symptoms, cognitive mechanisms that transmit vulnerability between symptom clusters are largely unknown. Dampening, positive rumination, and brooding are three cognitive predictors of depression, with rumination theoretically indicated as a transdiagnostic vulnerability through amplifying and diminishing affect in response to events. Specifically, the excess negative affect and lack of positive affect characteristic of depressive symptoms and underlying somatic symptoms may cause and be caused by cognitive responses to events. Therefore, the current study examined whether comorbidity between depressive and somatic symptoms may be explained by the cognitive mechanisms of dampening and positive rumination in response to positive events and brooding in response to negative events among adults () across eight weeks of assessment. We hypothesized that greater dampening and brooding would reciprocally predict greater depressive and somatic symptoms, while greater positive rumination would reciprocally predict fewer depressive and somatic symptoms. Mediation analyses in AMOS 22 indicated that dampening and brooding mediated reciprocal pathways between depressive and somatic symptoms, but positive rumination did not. Findings propose dampening and brooding as mechanisms of the reciprocal relationship between depressive and somatic symptoms through diminishing positive affect and amplifying negative affect in response to positive and negative events.

- Childhood Trauma and Its Relation to Chronic Depression in Adulthood
Abstract: There is a large consensus indicating that childhood trauma is significantly involved in the development of depression. The aim of this study was to examine the prevalence of retrospectively recalled childhood trauma in chronically depressed patients and to investigate a more specific relationship between trauma type and depression. We further asked for the influence of multiple experiences of childhood trauma on the vulnerability to a chronic course of depression in adulthood. 349 chronically depressed patients of the German LAC Depression Study completed the Childhood Trauma Questionnaire, a self-report measure of traumatic experiences in childhood. 75.6% of the chronically depressed patients reported clinically significant histories of childhood trauma. 37% of the chronically depressed patients reported multiple childhood traumatization. Experiences of multiple trauma also led to significantly more severe depressive symptoms. Stepwise multiple regression analysis suggested that childhood emotional abuse and sexual abuse were significantly associated with a higher symptom severity in chronically depressed adults. Yet, expanding the regression model for multiple exposures showed that multiplicity was the only remaining significant predictor for symptom severity in chronically depressed patients. Clinical implications suggest a precise assessment of childhood trauma in chronically depressed patients with a focus on emotional abuse, sexual abuse, and multiple exposures to childhood trauma. This trial is registered with registration number ISRCTN91956346.

- Seasonal Affective Disorder: An Overview of Assessment and Treatment
Abstract: Seasonal affective disorder or SAD is a recurrent major depressive disorder with a seasonal pattern usually beginning in fall and continuing into winter months. A subsyndromal type of SAD, or S-SAD, is commonly known as “winter blues.” Less often, SAD causes depression in the spring or early summer. Symptoms center on sad mood and low energy. Those most at risk are female, are younger, live far from the equator, and have family histories of depression, bipolar disorder, or SAD. Screening instruments include the Seasonal Pattern Assessment Questionnaire (SPAQ). Typical treatment includes antidepressant medications, light therapy, Vitamin D, and counselling. This paper provides an overview of SAD.

- Depressive Symptoms during an Acute Schizophrenic Episode: Frequency and
Abstract: Introduction. Depressive symptoms are common in schizophrenia and are associated with poorer functioning, lower quality of life, and an elevated risk of suicidal behaviour. There are few studies on the occurrence and correlates of these symptoms in acutely ill patients with schizophrenia. Method. 72 acutely ill patients with schizophrenia were assessed for depression using the Calgary Depression Scale for Schizophrenia (CDSS). A cut-off score of ≥6 on the CDSS was used to identify clinically significant depressive symptoms. The relationship between depression and illness variables, including psychotic symptom dimensions as measured by the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), was examined. Results. Eleven (15.3%) patients had clinically significant depressive symptoms. These patients scored higher on the positive and general psychopathology scales of the PANSS and had higher rates of suicidal behavior and poorer functioning. The severity of depressive symptoms was positively correlated with the PANSS positive subscale and negatively correlated with the PANSS negative subscale. Discussion. These findings confirm previous reports that depressive symptoms in active schizophrenia is related to the severity of positive psychotic symptoms and is a risk factor for suicidal behaviour in these patients.

- Sex Differences in Genetic and Environmental Influences on Adolescent
Depressive Symptoms: A Meta-Analytic Review
Abstract: Although sex difference in the mean level of depressive symptoms has been well established, the sex difference in genetic and environmental influences on adolescent depressive symptoms is unclear. The current study conducted a meta-analysis of twin studies on sex differences in self- and parent-reported adolescent depressive symptoms. For self-reports, genetic factors influenced adolescent depressive symptoms equally for boys and girls, accounting for 46% of variation, but shared environmental factors had stronger impacts on adolescent girls’ versus boys’ depressive symptoms (13% versus 1% of the variance). For parent-reports, genetic, shared, and nonshared environmental factors influenced adolescent depressive symptoms equally, with separate estimates of 34%, 35%, and 31%. The implications of sex difference in genetic and environmental etiologies of depressive symptoms are discussed.

- Depressive Symptoms: The Interaction between Rumination and Self-Reported
Abstract: Objective. Prior research has found consistent support that rumination and insomnia are important risk factors for depressive symptoms. The aim of the present cross-sectional study is to examine the interaction between these two previously well-established risk factors (i.e., rumination and insomnia) in the explanation of depressive symptoms. Design. A total of 417 participants (277 women) with a mean age of 39 (SD = 17.59; range 18–85) completed a cross-sectional survey. Main Outcome Measures. Participants filled out the Response Rumination Scale, the Athens Insomnia Scale, and the short version of the Center for Epidemiologic Studies Depression Scale. Results. It was predicted and found that self-reported insomnia moderated the relationship between rumination and depressive symptoms. We found that particularly participants who reported higher levels of rumination as well as insomnia had the highest depressive symptoms. Conclusion. This study is the first to suggest that particularly individuals exhibiting both self-reported insomnia and higher levels of rumination also report higher levels of depressive symptoms. Health professionals screening for mental problems should be aware of this specific combination of insomnia and rumination. Explanations for this moderation effect were discussed in light of study’s limitations.

- No Association of BDNF, COMT, MAOA, SLC6A3, and SLC6A4 Genes and
Depressive Symptoms in a Sample of Healthy Colombian Subjects
Abstract: Background. Major depressive disorder (MDD) is the second cause of years lived with disability around the world. A large number of studies have been carried out to identify genetic risk factors for MDD and related endophenotypes, mainly in populations of European and Asian descent, with conflicting results. The main aim of the current study was to analyze the possible association of five candidate genes and depressive symptoms in a Colombian sample of healthy subjects. Methods and Materials. The Spanish adaptation of the Hospital Anxiety and Depression Scale (HADS) was applied to one hundred eighty-eight healthy Colombian subjects. Five functional polymorphisms were genotyped using PCR-based assays: BDNF-Val66Met (rs6265), COMT-Val158Met (rs4680), SLC6A4-HTTLPR (rs4795541), MAOA-uVNTR, and SLC6A3-VNTR (rs28363170). Result. We did not find significant associations with scores of depressive symptoms, derived from the HADS, for any of the five candidate genes (nominal values >0.05). In addition, we did not find evidence of significant gene-gene interactions. Conclusion. This work is one of the first studies of candidate genes for depressive symptoms in a Latin American sample. Study of additional genetic and epigenetic variants, taking into account other pathophysiological theories, will help to identify novel candidates for MDD in populations around the world.

- Ketamine, Transcranial Magnetic Stimulation, and Depression Specific Yoga
and Mindfulness Based Cognitive Therapy in Management of Treatment
Resistant Depression: Review and Some Data on Efficacy
Abstract: Depression affects about 121 million people worldwide and prevalence of major depressive disorder (MDD) in US adults is 6.4%. Treatment resistant depression (TRD) accounts for approximately 12–20% of all depression patients and costs $29–$48 billion annually. Ketamine and repetitive transcranial magnetic stimulation (rTMS) have useful roles in TRD, but their utility in long term is unknown. As per the latest literature, the interventions using Yoga and meditation including the mindfulness based cognitive therapy (MBCT) have been useful in treatment of depression and relapse prevention. We present a review of rTMS, ketamine, and MBCT and also report efficacy of a depression specific, innovative, and translational model of Yoga and mindfulness based cognitive therapy (DepS Y-MBCT), developed by the first author. DepS Y-MBCT as an adjunctive treatment successfully ameliorated TRD symptoms in 27/32 patients in an open label pilot trial in TRD patients. Considering the limitations of existing treatment options, including those of ketamine and rTMS when used as the sole modality of treatment, we suggest a “tiered approach for TRD” by combining ketamine and rTMS (alone or along with antidepressants) for rapid remission of acute depression symptoms and to use DepS Y-MBCT for maintaining remission and preventing relapse.

- Elevated Risk of Suicidal Ideation in HIV-Positive Persons
Abstract: Globally, suicide and HIV/AIDS remain two of the greatest healthcare issues, particularly in low- and middle-income countries. Several studies have observed a relationship between suicidal behaviour and HIV/AIDS. Materials and Methods. The main objective of this research was to determine the prevalence of elevated risk of suicidal ideation in HIV-positive persons immediately following voluntary HIV counselling and testing (VCT). The study sample consisted of adult volunteers attending the VCT clinic at a university-affiliated, general state hospital. Participants completed a sociodemographic questionnaire, Beck’s Hopeless Scale, and Beck’s Depression Inventory. Results. A significantly elevated risk of suicidal ideation was found in 83.1% of the patients who tested seropositive. Despite a wide age range in the cohort studied, the majority of patients with suicidal ideation were males in the younger age group (age < 30 years), consistent with the age-related spread of the disease and an increase in suicidal behaviour in younger people. Relevant associated variables are discussed. Conclusion. The results serve as important markers that could alert healthcare professionals to underlying suicide risks in HIV-positive patients. It is recommended that screening for elevated risk of suicidal ideation and prevention of suicidal behaviour should form a routine aspect of comprehensive patient care at VCT clinics.

- Increasing Understanding in Children of Depressed Parents: Predictors and
Moderators of Intervention Response
Abstract: We evaluated predictors and moderators of differential response to two family-based depression prevention programs for families with a depressed parent: a clinician-facilitated intervention and a lecture group intervention. Individual and family level variables were examined using regression analyses with generalized estimating equations. For the outcome of child understanding of depression, parental changes in child-related behaviors and attitudes predicted greater child understanding (). For the parent outcome of behavior and attitude change, across intervention conditions, younger parent age (), female parent gender (), more chronic and severe parental depression history (), lower SES (), and single-parent status () were associated with better outcomes across conditions. Effect sizes were moderate, ranging from 0.4 to 0.7 SD. Family and marital functioning were not found to be predictors of any outcomes. When both parents were depressed at baseline, there was no difference in the clinician- versus lecture-based approach, and when only the father was depressed, families reported more changes with the clinician condition than with the lecture condition (). Findings from this study can help identify intervention strategies that are appropriate for different types of at-risk individuals and families.

- Turkish Version of the Cognitive Distortions Questionnaire: Psychometric
Abstract: Cognitive distortions are interrelated with all layers of cognitions, and they may be part of the treatment once they are accessed, identified, labeled, and changed. From both a research and a clinical perspective, it is of utmost importance to disentangle cognitive distortions from similar constructs. Recently, the Cognitive Distortions Questionnaire (CD-Quest), a brief and comprehensive measure, was developed to assess both the frequency and the intensity of cognitive distortions. The aim of the present study was to assess the psychometric properties of the Turkish version of the CD-Quest in a psychiatric outpatient sample. Demographic and clinical data of the participants were analyzed by descriptive statistics. For group comparisons, Student’s -test was applied. An exploratory principal components factor analysis was performed, followed by an oblique rotation. To assess the internal consistency of the scale Cronbach’s was computed. The correlation coefficient was calculated for test-retest reliability over a 4-week period. For concurrent validity, bivariate Pearson correlation analyses were conducted with the measures of mood severity and negatively biased cognitions. The results revealed that the scale had excellent internal consistency, good test-retest reliability, unidimensional factor structure, and evidence of concurrent and discriminant validity.

Abstract: Background. The emotional consequences of diabetes have been scrutinized by a number of investigative teams and there are varying reports about the association of depression with type 2 diabetes mellitus. However, there is limited data about this in Ethiopia. Therefore, the purpose of this study was to assess the prevalence of comorbid depression among type 2 diabetic outpatients. Methods and Materials. Institution based cross-sectional study design was conducted on a random sample of 276 type 2 diabetic outpatients from Black Lion General Specialized Hospital. Systematic random sampling technique was used to get these individual patients from 920 type 2 diabetic outpatients who have an appointment during the data collection period. Patients’ depression status was measured using Patient Health Questionnaire 9 (PHQ 9). Result. Totally 264 type 2 diabetic outpatients were interviewed with a response rate of 95.6%. The prevalence of depression among type 2 diabetic outpatients was 13%. Based on PHQ 9 score, 28.4% (75) fulfilled the criteria for mild depression, 12.1% (32) for moderate depression, 2.7% (7) for moderately severe depression, and 1.5% (4) for severe depression. But 45.8% (121) of patients had no clinically significant depression. Conclusion. This study demonstrated that depression is a common comorbid health problem in type 2 diabetic outpatients with a prevalence rate of 13%.

- Memory Impairment following Acute Tricyclic Antidepressants Overdose
Abstract: Background. Psychiatric consultation is necessary for all patients with intentional poisoning and its reliability depends on the proper function of patients’ memory performance. This study aimed to determine the possible memory impairment following acute TCAs’ poisoning. Materials and Methods. In this cross-sectional study, patients with acute TCAs poisoning were allocated to two groups of severe poisoning (with coma, seizures, cardiac arrhythmias, hypotension, and a wide QRS complex) and mild-to-moderate poisoning according to their clinical presentation at the time of hospital admission. All patients underwent memory performance test both immediately and 24 hours after their initial consciousness after admission, using Wechsler Memory Scale (WMS-IV). Results. During the study period, 67 TCA-poisoned patients (aged, 20–64 years) were evaluated, of which 67.2% were female. The mean memory scores of patients immediately and 24 hours after the initial consciousness were and , respectively (). Twenty-four hours after the initial consciousness, memory score was statistically correlated with the amount of ingested drug and the intoxication severity. Conclusion. Following the recovery from somatic symptoms of acute TCA poisoning, patients may still suffer from memory impairment and it seems that this time is not suitable for performing a reliable psychiatric consultation.

- Short-Term Effects of Electroconvulsive Therapy on Subjective and
Actigraphy-Assessed Sleep Parameters in Severely Depressed Inpatients
Abstract: Background. Sleep disturbances are a key feature of major depression. Electroconvulsive treatment (ECT) may improve polysomnography-assessed sleep characteristics, but its short-term effects on actigraphy-assessed and subjective sleep characteristics are unknown. We therefore aimed to assess the effects of ECT on subjective and objective sleep parameters in a proof-of-principle study. Methods. We assessed subjective and objective sleep parameters in 12 severely depressed patients up to 5 consecutive days during their ECT course, corresponding to a total of 43 nights (including 19 ECT sessions). The 12 patients were 83% female and on average 62 (standard deviation (SD) 14) years old and had an average MADRS score of 40 at baseline (SD 21). Results. Subjective and objective sleep parameters were not directly affected by ECT. The subjective sleep efficiency parameter was similar on the day after ECT and other days. ECT did not affect the number of errors in the Sustained Attention to Response Task. Patients subjectively underestimated their total sleep time by 1.4 hours () compared to actigraphy-assessed sleep duration. Conclusion. ECT did not affect subjective and actigraphy-assessed sleep in the short term. Depressed patients profoundly underestimated their sleep duration.
