Abstract
BACKGROUND Our study examined whether the early-onset depression phenotype among young adults (probands) is associated with the metabolic syndrome (MetS) and its components, and if MetS characterizes unaffected but high-risk siblings of probands. METHODS We studied three groups of young adults (Mage = 25 years, s.d. = 3.84 years): probands with histories of childhood onset depression - i.e. early-onset phenotype - (n = 293), their unaffected siblings (high-risk siblings, n = 273), and healthy controls (n = 171). Participants completed a full psychiatric interview, physical and laboratory assessments, and self-rating scales. MetS was defined using the criteria of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (). RESULTS Early-onset depression phenotype and being a high-risk sibling were associated with higher MetS composite scores relative to that of controls, but did not differ from one another. With regard to MetS components: Probands and siblings had similarly larger waist circumference and lower HDL than did controls, while siblings and controls had lower triglyceride levels than did probands but did not differ from one another. Groups did not differ on glucose levels and SBP. CONCLUSIONS Our study extends the literature on the association between MetS and depression and underscores the importance of depression phenotypes: failure to account for the clinical heterogeneity of depression may partly underlie the inconsistent findings regarding its relation to MetS. The results also suggest that, in depression-prone populations, MetS may predate and possibly function as a risk factor for eventual depression.

Abstract
BACKGROUND Ecological momentary assessment (EMA) is a high-frequency ambulatory data collection approach that has come to be widely used in emotion research. It therefore is timely to examine two features of EMA needed for a successful study: compliance with survey prompts and high affective yield (survey prompts that capture affect experience). We posit that compliance may be subject to temporal variation (time-of-day, days in study) and individual differences (depression history), and that affective yield may also differ by social context. METHODS We examined these issues in a sample of 318 young adults (Mage = 24.7 years, SD = 2.7), including those with current depression (n = 28), remitted depression (n = 168) and never-depressed controls (n = 122) who participated in a 7-day EMA protocol of negative and positive affect (NA and PA, respectively). RESULTS The overall compliance rate was 91% and remained stable across the survey week. However, subjects were significantly less likely to respond to the first daily prompt compared to those that followed. The likelihood of capturing NA and PA decreased with each EMA protocol day, and affective yield across social contexts differed by participants' depression status. LIMITATIONS The sample was largely comprised of White young adults. Relative to the remitted and control groups, the sample size for the currently depressed was unbalanced. CONCLUSION Researchers can optimize compliance and affective yield within EMA by considering depression, time-of-day, study duration, and social context. Clinicians using EMA to monitor affect may benefit from considering these parameters.

Adiposity and Smoking Mediate the Relationship Between Depression History and Inflammation Among Young Adults. Int J Behav Med 2022; 29:787-795.

Abstract
BACKGROUND Depression is associated with inflammation, but the mechanisms underlying this association are unclear. We examined adiposity and smoking as potential pathways through which childhood depression may lead to an elevated inflammatory status among young adults. METHODS The sample included 294 subjects with histories of depression (probands), 270 never-depressed siblings of probands (high-risk siblings), and 169 controls. C-reactive protein (CRP), interleukin-6 (IL-6), and soluble intercellular adhesion molecule-1 (sICAM-1) were assessed in serum samples. An adiposity score was computed from body mass index and waist circumference. Smoking behavior was evaluated during an interview. Mixed-effects models were used to test whether adiposity and smoking mediate the relationship between depression and inflammation. RESULTS Probands (p = .004), but not siblings (p = .071), had higher levels of sICAM-1 compared to controls. However, depression history and risk status had no direct effects on CRP (ps > .13) or IL-6 (ps > .16). Importantly, adiposity indirectly mediated the effect of group (probands vs. controls; siblings vs. controls) on all three inflammatory markers. Smoking indirectly mediated the effect of group (probands vs. controls; siblings vs. controls) on sICAM-1 only. CONCLUSIONS Among young adults, the adverse inflammatory consequences of depression history are significant for sICAM-1. Adiposity and smoking are pathways through which depression can indirectly impact several inflammatory markers, suggesting possible preventive interventions to improve the immunologic and cardiovascular health of depression-prone individuals.

Age related sex differences in maladaptive regulatory responses to sadness: A study of youths at high and low familial risk for depression. J Affect Disord 2021; 294:574-579.

Abstract
Offspring of parents with depression histories are at increased risk of developing depression and also report maladaptive ways of self-regulating sadness. Maladaptive regulation of sadness tends to be more prevalent among females than males and has been proposed as one explanation of sex differences in depression rates that emerge around mid-adolescence. However, there is scant information about the age at which the sex differences in maladaptive regulatory responses become evident and whether such age-related sex differences vary depending on depression risk. The present study examined two samples aged 8-18 years: 86 offspring of emotionally healthy parents and 98 offspring of parents with depression histories. Subjects were clinically assessed and provided self-reports of maladaptive responses to sadness. In the combined samples, sex differences in maladaptive responses were significant at age 12.5 years and older ages (i.e., chronologically earlier than the documented emergence of sex differences in depression). While in the high-risk group, sex differences in maladaptive regulatory responses were significant at 12.11 years of age and older, in the low-risk group there was no age at which sex differences were significant. Our findings support the possible mechanistic role of maladaptive emotion regulation in the emergence of sex disparities in depression rates and have implications for prevention.

Abstract
OBJECTIVES The literature on childhood-onset depression and future compromised vascular function is suggestive but limited. The objective of this study was to determine if arterial stiffness, a predictor of future cardiovascular disease (CVD), measured in young adulthood, is associated with childhood-onset depression. METHODS Cardiometabolic risk factors and pulse wave velocity (PWV), a measure of arterial stiffness, were cross-sectionally assessed in young adults with a history of childhood-onset depression (clinical diagnosis of major depressive episode or dysthymic disorder; N = 294 probands; initially recruited via child mental health facilities across Hungary; mean age of first depressive episode = 10.4 years), their never-depressed full biological siblings (N = 269), and never-depressed controls (N = 169). The mean ages of probands, siblings, and controls at the PWV visit were 25.6, 25.0, and 21.7 years, respectively, and 8.8% of the probands were in a current depressive episode. RESULTS Controlling for age, sex, age*sex, education, and family clusters, PWV (m/s) did not statistically differ across the groups (probands = 7.01; siblings = 6.98; controls = 6.81). However, after adjusting for key covariates, there were several across-group differences in CVD risk factors: compared to controls, probands and siblings had higher diastolic blood pressure and lower high-density lipoprotein cholesterol, probands had higher triglycerides, and siblings had higher body mass index (all p < 0.05). CONCLUSION We found limited evidence of an association between a history of childhood-onset depression and young adulthood arterial stiffness. However, our findings of elevated cardiovascular risk factors in those with childhood-onset depression suggest that pediatric depression may predispose to increased CVD risk later in life and warrants further investigation.

Adversity and Depression: The Moderating Role of Stress Reactivity among High and Low Risk Youth. JOURNAL OF ABNORMAL CHILD PSYCHOLOGY 2020; 47:1391-1399.

Abstract
Adverse life events have been causally linked to depression among youth at high risk for depression. But given that not all high-risk youth develop depression following adversity, individual differences in various processes, including physiological reactivity to stress, are likely to be at play. This longitudinal prospective study tested the hypothesis that, among high-risk youth exposed to adversities, extent of physiological reactivity to laboratory stress (indexed as respiratory sinus arrhythmia; RSA) would predict subsequent depressive symptoms. Subjects were youth at high (n = 80) and low (n = 74) familial risk for depression. At Time 1 (T1), RSA was assessed during a cognitive stress task. At Time 2 (T2) about 2 years later, parents reported on adversities experienced by their offspring during the interim. At T1 and T2, youth received a diagnostic evaluation, which included assessment of their depressive symptoms. The three-way interaction of group-X-adversities-X-RSA predicted T2 depressive symptoms (controlling for T1 depressive symptoms). This interaction was mostly driven by the moderating effect of RSA among high-risk youth, such that adversities predicted higher depressive symptoms for those who displayed greater RSA reactivity to stress. Among low-risk youth, an inverse marginal moderating effect of RSA was found, such that adversities tended to predict depressive symptoms for those who displayed blunted RSA reactivity to stress. Thus, high physiological stress reactivity appears to be an additional risk factor for depressive symptoms only among youth at elevated risk for such outcomes, and should be taken into consideration in efforts to prevent depression in these populations.

Abstract
Youths at high risk for depression have been shown to have problems in repairing their own sad mood. Given that sympathetic arousal has been implicated both in the experience and regulation of affect, an atypical pattern of arousal may be one of the factors that contribute to mood repair problems. In the current study, we measured sympathetic arousal of never-depressed youths at high (n = 56) and low (n = 67) familial risk for depression during sad mood induction and instructed mood repair. Sympathetic arousal was indexed by skin conductance level (SCL) and cardiac pre-ejection period (PEP); mood repair outcome was indexed by self-rated affect. High-risk youths demonstrated increased SCL during sadness induction, which persisted during mood repair; low-risk youths evidenced increased SCL only during mood repair. Shortened PEP was evident only among high-risk youths and only during mood repair. Furthermore, shortened PEP during mood induction predicted less successful mood repair in the low-risk but not in the high-risk group. The findings suggest that: (a) depression-prone youths differ from control peers in patterns of sympathetic responses to emotional stimuli, which may impair their ability to relieve sadness, and (b) activation patterns differ across subsystems (SCL vs. PEP) of sympathetic activity, in conjunction with depression risk status.

Abstract
BACKGROUND As the rates of suicidal behaviors continue to rise, research is needed that can facilitate prevention. The present study therefore examined whether a modifiable process, dysfunctional regulation of sadness (maladaptive mood repair), predicts a range of suicidal behaviors and if its impact is affected by risk and protective factors. METHODS Young adults with histories of childhood-onset mood disorder (COMD) (n = 173) or no histories of major psychiatric illness (controls, n = 96) were followed for approximately 3 years. Self-rated questionnaires and psychiatric evaluations were administered at study entry (T1) and across the follow-up (T2) and clinicians assessed the DSM-range of non-fatal suicidal behaviors. We hypothesized that the impact of depression on suicidal behaviors was mediated by dysfunctional regulation of sadness. RESULTS At T1, 90% of the COMD group had histories of various suicidal behaviors; 63% had past suicide attempts. During follow-up, 40% exhibited suicidal behaviors; 7% reported suicide attempts. Controlling for prior suicidal behaviors, T1 maladaptive mood repair predicted suicidal behavior during the follow-up and differentiated recurrent thoughts of death from other forms of suicidality. Protective and risk factors lost their predictive power in the presence of maladaptive mood repair. LIMITATIONS Few control cases exhibited suicidal behavior during the follow-up and the high inter-correlations among several key variables constrained the models that could be fitted. CONCLUSIONS Programs to prevent suicidal behavior among high-risk individuals should include maladaptive mood repair as an intervention target. Further research is needed on whether recurrent thoughts of death constitute a valid index of suicidality.

Abstract
Depression has been associated with high blood pressure (BP). However, the mechanisms of the relation between depression and high BP are unclear. We therefore examined whether impaired cardiac vagal control, indexed as low levels of resting respiratory sinus arrhythmia (RSA), serves as a route from depression to high BP. The sample included 125 subjects with histories of depression (probands), 123 never depressed siblings of probands (high-risk siblings), and 156 controls. Resting RSA was assessed at Time 1 (T1) along with BP when subjects were adolescents (Mage = 16.3 years); systolic and diastolic BP (SBP and DBP) were measured again at Time 2 (T2) when subjects were young adults (Mage = 22.3 years). Linear mixed-effects models were used to examine the group differences in resting RSA and T2 BP outcomes and to test for RSA mediation of the relation between depression (history or being at high risk) and BP. Resting RSA was lower among probands than controls but was similar among high-risk siblings and controls, while the subject groups did not differ in T2 SBP or DBP. Controlling for T1 BP, depression history indirectly affected T2 DBP (but not SBP) through resting RSA. The findings suggest that, although the direct detrimental effects of depression on BP are not yet evident in young adulthood, among those with depression histories, impaired cardiac vagal control appears to serve as a mechanism of elevated DBP.

Abstract
Background: Attention deficit and hyperactivity disorder (ADHD) is one of the most common mental disorders in childhood. Recently, several studies showed the high suicide risk of patients with ADHD; however, most of these studies had a cross-sectional design. Aims: The aim of the current research is to complete a systematic review of published studies which investigate the suicide risk of ADHD patients with longitudinal design. Methods: The systematic search was made on OVID Medline, PsychInfo, PubMed, Scopus, and Web of Science. The search terms were (ADHD OR attention deficit hyperactivity disorder) AND (suicide OR suicidal OR suicidality) AND (follow-up OR longitudinal study OR prospective study). The inclusion criteria were as follows: written in English; the participants were under 18 years at baseline; longitudinal, prospective studies; ADHD population at baseline and at follow-up; and suicide behavior as a primary outcome. The exclusion criteria were as follows: the study did not contain empirical data and reviews/meta-analyses and studies which aimed to investigate the drug treatment efficacy of ADHD. Results: After the screening process, 18 papers were included in the systematic review. Ten articles were altogether published in the last 5 years. The range of follow-up periods varied between 2 and 17 years. Several different assessment tools were used to investigate the symptoms and/or the diagnosis of ADHD and the suicidal risk. Nine studies enrolled children aged under 12 at baseline, and three studies used birth cohort data, where there was no strict age-based inclusion criteria. A total of 17 studies found a positive association between ADHD diagnosis at baseline and the presence of suicidal behavior and/or attempts at the follow-up visits. Limitations: The main limitation of this review is the methodological heterogeneity of the selected studies. A further limitation is the relatively low number of studies that examined a population with balanced gender ratios. Additionally, only one study published data about the treatment of ADHD. Finally, though we carefully chose the keywords, we still may be missing some relevant papers on this topic. Conclusions: In spite of the methodological diversity of the included studies, the results of the current systematic review highlight the importance of screening suicidality in the long term in patients with ADHD. Therefore, further studies that compare the suicidal risk of treated and untreated groups of ADHD patients in the long term are needed.

Abstract
The aim of the present study was to examine whether offspring at high and low familial risk for depression differ in the immediate and more lasting behavioural and physiological effects of hedonically-based mood repair. Participants (9- to 22-year olds) included never-depressed offspring at high familial depression risk (high-risk, n = 64), offspring with similar familial background and personal depression histories (high-risk/DEP, n = 25), and never-depressed offspring at low familial risk (controls, n = 62). Offspring provided affect ratings at baseline, after sad mood induction, immediately following hedonically-based mood repair, and at subsequent, post-repair epochs. Physiological reactivity, indexed via respiratory sinus arrhythmia (RSA), was assessed during the protocol. Following mood induction and mood repair, high- and low-risk (control) offspring reported comparable changes in levels of sadness and RSA. However, sadness increased among high-risk offspring following the post-repair epoch, whereas low-risk offspring maintained mood repair benefits. High-risk/DEP offspring also reported higher levels of sadness following the post-repair epoch than did low-risk offspring. Change in RSA did not differ across the three offspring groups. Self-ratings confirm that one source of difficulty associated with depression risk is diminished ability to maintain hedonically-based mood repair gains, which were not apparent at the physiological level.

Abstract
Suicidal thoughts and behaviors (STBs) have been associated with emotion dysregulation and atypical responses to affective and stressful stimuli. To investigate the psychophysiology involved, we measured changes in respiratory sinus arrhythmia (RSA) and cardiac pre-ejection period (PEP; indexing parasympathetic and sympathetic functioning, respectively) in response to stressful- and sadness-eliciting laboratory probes. Our sample included adolescents with a history of depression and STBs (n = 177), adolescents with a history of depression but no history of STBs (n = 47), and healthy controls (n = 175). The outcome of interest was the most severe form of clinician-rated STBs across the subject's lifetime. In partial support of our hypotheses, during the stressful task, adolescents with a history of depression and STBs did not evidence the RSA decrease that was exhibited by controls and displayed greater PEP shortening compared to ever-depressed adolescents with no lifetime STBs. No group differences were found in either RSA or PEP reactivity to the sadness-eliciting stimulus. As expected, severity of STBs was positively correlated with the extent of PEP shortening during the stressful task. The results suggest that adolescents with a history of depression and STBs experience blunted parasympathetic responses to stress along with compensatory efforts. Our findings contribute to a better understanding of STBs among youths and underscore that future studies should examine physiological risk factors for these psychopathological outcomes.

Emotion Regulation Among Adolescents With Pediatric Depression As a Function of Anxiety Comorbidity. Front Psychiatry 2019; 10:722. [PMID: 31649566 PMCID: PMC6790632 DOI: 10.3389/fpsyt.2019.00722] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Accepted: 09/09/2019] [Indexed: 11/13/2022] Open
Abstract
Background: Both depression and anxiety (two of the most common internalizing psychopathologies among youths) are associated with difficulties in emotion regulation (ER). Little is known about whether anxiety as a comorbid condition has an effect on the habitual use of different ER strategies in youngsters with depression histories. We aimed 1) to compare ER in adolescents with histories of childhood onset major depressive disorder (MDD) with and without comorbid anxiety and 2) to examine whether certain ER response clusters (Cognitive, Social, and Behavioral/Physical) characterize comorbid children and adolescents. Methods: We analyzed data on 217 youth (11-18 years old) with depression history: 85 subjects with lifetime anxiety comorbidity (comorbid group) and 132 without lifetime anxiety (non-comorbid group). Psychiatric diagnosis was established by a comprehensive Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-based diagnostic procedure. ER strategies were examined via the self-rated "Feelings and Me" Child version questionnaire (FAM-C). Results: The comorbid group used maladaptive ER strategies significantly more frequently than the non-comorbid youngsters. The Behavioral/Physical and Social ER skills, especially those reflecting social withdrawal and self-harm, were responsible for the higher maladaptive scores. Limitations: Because our study is a cross-sectional analysis, we have no information about the development or the onset of maladaptive ER strategies. Therefore, we were unable to examine whether maladaptive ER was a risk factor or a consequence of the internalizing psychopathology and comorbidity. Conclusions: Comorbid anxiety worsens the impaired use of ER strategies in depression-prone youths. Further longitudinal research is needed to explore the causal role of dysfunctional ER in the development of internalizing psychopathology.

Abstract
BACKGROUND Family dysfunction has been proposed as one of the environmental mechanisms whereby risk of depression is transmitted from mothers to their children. Using our sample of offspring at high and low familial risk for depression, we hypothesized that: a) high-risk offspring (n = 79) and their mothers will report more extensive family dysfunction than low-risk offspring (n = 82) and their mothers, b) family dysfunction will predict the extent of offspring's depressive symptoms, and c) family dysfunction will mediate the impact of mother's depression on offspring's depressive symptoms. METHODS The study enrolled 161 offspring of parents who, in a previous study, were ascertained to have either childhood onset mood disorder or no history of a major psychiatric disorder. Parents completed questionnaires and a clinical interview about themselves, their offspring, and the family, while offspring also completed questionnaires about themselves and the family. RESULTS We found support for all three hypotheses. The significant indirect effect between maternal depression and offspring depressive symptoms was driven primarily by offspring's, but not mothers', reports of family dysfunction. LIMITATIONS Although our assessment of mother's early history of depression was done in a previous study, it is important to note that our results do not inform about causality because of the present study's cross-sectional nature. CONCLUSIONS The results highlight the importance of detecting and treating family dysfunction, particularly via offspring report, as one way to lower the risk of depression transmission from mothers to their children.

Abstract
This prospective, naturalistic study examined the association between major loss life experiences, other psychiatric risk factors (depression, hopelessness, and anxiety), and suicidal thoughts and behaviors (STBs) among adolescents followed through young adulthood for up to 14 years. Major loss life events were related to subsequent increases in STBs. Major loss life events were primarily related to increases in suicide ideation in the presence of lower levels of other risk factors. There was a bidirectional relationship between major losses and other risk factors. Implications for the association between loss experiences, other risk factors, and future STBs are discussed.

Abstract
The internalizing spectrum of psychiatric disorders-depression and anxiety-are common, highly comorbid, and challenging to treat. Individuals with childhood onset depression have a particularly poor prognosis. There is compelling evidence that individuals with depression display reduced resting-state EEG activity at sensors overlying the left prefrontal cortex, even during periods of remission, but it remains unknown whether this asymmetry is evident among individuals with a comorbid anxiety disorder. Here, we demonstrate that women with a history of childhood onset depression and no anxiety disorder (n = 37) show reduced left lateral frontal activity compared to psychiatrically healthy controls (n = 69). In contrast, women with a history of childhood onset depression and pathological levels of anxious apprehension (n = 18)-as indexed by a current generalized anxiety disorder, obsessive compulsive disorder, or separation anxiety disorder diagnosis-were statistically indistinguishable from healthy controls. Collectively, these observations suggest that anxious apprehension can mask the relationship between prefrontal EEG asymmetry and depression. These findings have implications for understanding (a) prefrontal EEG asymmetry as a neurophysiological marker of depression, (b) the comorbidity of depression and anxiety, and (c) failures to replicate the relationship between prefrontal EEG asymmetry and depression. More broadly, they set the stage for developing refined interventions for internalizing psychopathology.

Abstract
Suicide is the second leading cause of death among youth ages 10-24. An estimated 1.5 million US adolescents receive their primary health care in the emergency department (ED); this is particularly true for low-income and minority youths who often lack a regular source of care. ED visits can provide a window of opportunity to screen and identify youths with suicide and mental health risk, triage youths based on need, and facilitate effective follow-up care. Recently developed brief therapeutic assessment approaches have demonstrated success in improving rates of follow-up care after discharge from the ED. Furthermore, there is some data supporting clinical benefits when youths receive evidence-based outpatient follow-up care. ED screening combined with effective follow-up, therefore, may provide one strategy for improving mental health and reducing health disparities in our nation. This paper reviews the context in which ED screenings occur, available tools and strategies, and evidence for the effectiveness of tested approaches.

Abstract
BACKGROUND The episodic nature of major depressive disorder (MDD) in clinically referred adults has been well-characterized, particularly by the NIMH Collaborative Depression Study. Previous work has established that MDD also is episodic prior to adulthood, but no study has yet provided comprehensive information on the actual course of MDD in clinically referred juveniles. Thus, the present investigation sought to characterize recovery, recurrence, and their predictors across multiple episodes of MDD in initially 8- to 13-year-old outpatients (N=102), and to estimate freedom from morbidity ("well-time") across the years. METHOD Clinically referred youngsters with MDD were repeatedly assessed in an observational study across two decades (median follow up length: 15 years). Survival analytic techniques served to model recovery from the 1st, 2nd and 3rd lifetime episodes of MDD, the risk of developing the 2nd, 3rd, and 4th episodes, and the effects of traditional psychosocial and clinical predictors of outcomes. "Well-time" across the follow-up and its predictors also were examined. RESULTS Recovery rates ranged from 96% to 100% across MDD episodes; episode lengths ranged from 6 to 7 months. Up to 72% of those recovered from the first episode of MDD had a further episode; median inter-episode intervals were about 3-5 years. No single demographic, social, or clinical variable, nor treatment, consistently predicted recovery/recurrence. Psychiatric morbidity over time derived mostly from non-affective disorders, which, however, did not alter the course of MDD. LIMITATIONS The sample was relatively small and power to detect small effects further declined with each MDD episode recurrence. CONCLUSIONS Echoing findings on adults, the course of pediatric-onset MDD in this clinical sample was unequivocally episodic. Traditional course predictors had limited temporal stability, highlighting the need to examine novel predictor variables. The ongoing risk of depression episodes into the second and third decades of life suggests that prevention efforts should start in late childhood.

Abstract
OBJECTIVE Little is known about the patterns among individuals in the long-term course of suicidal thoughts and behaviors (STBs). The objective of this study was to identify developmental trajectories of STBs from adolescence through young adulthood, as well as risk and protective covariates, and nonsuicidal outcomes associated with these trajectories. METHOD A total of 180 adolescents (ages 12-18 years at recruitment) were repeatedly assessed over an average of 13.6 years (2,273 assessments) since their psychiatric hospitalization. Trajectories were based on ratings of STBs at each assessment. Covariates included psychiatric risk factors (proportion of time in episodes of psychiatric disorders, hopelessness, trait anxiety, impulsivity, and aggression in adulthood, sexual and physical abuse, parental history of suicidal behavior), protective factors (survival and coping beliefs, social support in adulthood, parenthood), and nonsuicidal outcomes (social adjustment and functional impairment in adulthood, school drop-out, incarcerations). RESULTS Using a Bayesian group-based trajectory model, 4 trajectories of STBs were identified: an increasing risk class (11%); a highest overall risk class (12%); a decreasing risk class (33%); and a low risk class (44%). The 4 classes were associated with distinct patterns of correlates in risk and protective factors and nonsuicidal outcomes. CONCLUSION Adolescents and young adults have heterogeneous developmental trajectories of STBs. These trajectories and their covariates may inform strategies for predicting STBs and targeting interventions for individuals at risk for suicidal behavior.

Abstract
INTRODUCTION Brain-derived neurotrophic factor (BDNF) polymorphisms have been examined for their contribution toward depression with equivocal results. More homogeneous phenotypes might be used to improve our understanding of genetic liability to depression. The aim of our study was to (a) test for an association between the BDNF Val66Met polymorphism and childhood-onset melancholic depression and (b) to examine the interactive effects of stressful life events (SLE) and the Val66Met polymorphism on the risk of childhood-onset melancholic depression. MATERIALS AND METHODS A total of 583 depressed probands were involved in this study (162 of the melancholic subtype). Diagnoses were derived through the Interview Schedule for Children and Adolescents - Diagnostic Version and life event data were collected using an Intake General Information Sheet. RESULTS Overall, 27.8% of the participants fulfilled the criteria for melancholy. In the melancholic group, the proportion of females was higher (53.1%), although there were more males in the overall depressed sample. We detected no significant differences in genotype or allele frequency between the melancholic and the nonmelancholic depressed group. The BDNF Val66Met polymorphism and SLE interaction was not significantly associated with the melancholy outcome. CONCLUSION In our study, females were more prone to developing the early-onset melancholic phenotype. To our knowledge, this is the first study to investigate the differentiating effect of the genotype and the G×E interaction on the melancholic phenotype in a large sample of depressed young patients. We did not find an association between the melancholic subtype of major depression and the BDNF genotype and SLE interaction in this sample, which is representative of the Hungarian clinic-referred population of depressed youths.

Abstract
BACKGROUND Impaired emotion regulation is increasingly recognized as a core feature of depressive disorders. Indeed, currently and previously depressed adults both report greater problems in attenuating sadness (mood repair) in daily life than healthy controls. In contrast, studies of various strategies to attenuate sad affect have mostly found that currently or previously depressed adults and controls were similarly successful at mood repair in the laboratory. But few studies have examined mood repair among depression-prone youths or the effects of trait characteristics on mood repair outcomes in the laboratory. METHODS Adolescents, whose first episode of major depressive disorder (MDD) had onset at age 9, on average (probands), and were either in remission or depressed, and control peers, watched a sad film clip. Then, they were instructed to engage in refocusing attention (distraction) or recalling happy memories. Using affect ratings provided by the youths, we tested two developmentally informed hypotheses about whether the subject groups would be similarly able to attenuate sadness via the two mood repair strategies. We also explored if self-reported habitual (trait) mood repair influenced laboratory performance. RESULTS Contrary to expectations, attention refocusing and recall of happy memories led to comparable mood benefits across subjects. Control adolescents reported significantly greater reductions in sadness than did depressed (Cohen's d = .48) or remitted (Cohen's d = .32) probands, regardless of mood repair strategy, while currently depressed probands remained the saddest after mood repair. Habitual mood repair styles moderated the effects of instructed (state) mood repair in the laboratory. CONCLUSIONS Whether depressed or in remission, adolescents with MDD histories are not as efficient at mood repair in the laboratory as controls. But proband-control group differences in mood repair outcomes were modest in scope, suggesting that the abilities that subserve affect regulation have been preserved in probands to some degree. Further information about the nature of mood repair problems among youths with depression histories would help to better understand the clinical course of MDD and to design personalized interventions for depression.

Abstract
Cardiac autonomic balance (CAB) indexes the ratio of parasympathetic to sympathetic activation (Berntson, Norman, Hawkley, & Cacioppo, 2008), and is believed to reflect overall autonomic flexibility in the face of environmental challenges. However, CAB has not been examined in depression. We examined changes in CAB and other physiological variables in 179 youth with a history of juvenile onset depression (JOD) and 161 healthy controls, in response to two psychological (unsolvable puzzle, sad film) and two physical (handgrip, and forehead cold pressor) challenges. In repeated measures analyses, controls showed expected reductions in CAB for both the handgrip and unsolvable puzzle, reflecting a shift to sympathetic relative to parasympathetic activation. By contrast, JOD youth showed increased CAB from baseline for both tasks (p's<.05). No effects were found for the forehead cold pressor or sad film tasks, suggesting that CAB differences may arise under conditions requiring greater attentional control or sustained effort.

Abstract
BACKGROUND Reward learning has been postulated as a critical component of hedonic functioning that predicts depression risk. Reward learning deficits have been established in adults with current depressive disorders, but no prior studies have examined the relationship of reward learning and depression in children. The present study investigated reward learning as a function of familial depression risk and current diagnostic status in a pediatric sample. METHOD The sample included 204 children of parents with a history of depression (n = 86 high-risk offspring) or parents with no history of major mental disorder (n = 118 low-risk offspring). Semistructured clinical interviews were used to establish current mental diagnoses in the children. A modified signal detection task was used for assessing reward learning. We tested whether reward learning was impaired in high-risk offspring relative to low-risk offspring. We also tested whether reward learning was impaired in children with current disorders known to blunt hedonic function (depression, social phobia, PTSD, GAD, n = 13) compared to children with no disorders and to a psychiatric comparison group with ADHD. RESULTS High- and low-risk youth did not differ in reward learning. However, youth with current anhedonic disorders (depression, social phobia, PTSD, GAD) exhibited blunted reward learning relative to nondisordered youth and those with ADHD. CONCLUSIONS Our results are a first demonstration that reward learning deficits are present among youth with disorders known to blunt anhedonic function and that these deficits have some degree of diagnostic specificity. We advocate for future studies to replicate and extend these preliminary findings.

Abstract
Evidence-based assessment (EBA) has been shown to improve clinical outcomes, but this practice is frequently not implemented in school mental health practice. This article reviews potential barriers to implementation and offers practical strategies for addressing these challenges. Several valid and reliable tools for assessment are reviewed, and information is provided on clinical use. Case examples of EBA implementation in school mental health settings are provided to illustrate how these tools can be used in everyday practice by school mental health clinicians.

Abstract
UNLABELLED Studies examining the association between childhood trauma exposure and neuroendocrine functioning have returned inconsistent findings. To date, few studies have accounted for the role exposure to different types of childhood trauma may have on different neuroendocrine adaptations, and no study has examined this association using multiple indices of hypothalamic-pituitary-adrenal axis (HPA-axis) functioning. The purpose of this study was to characterize the unique associations between exposure to physical abuse, emotional abuse, and non-intentional trauma, and multiple indices of HPA-axis functioning. METHODS A community sample of 138 youth (aged 9-16) completed the Socially Evaluated Cold Pressor Task (SE-CPT) while their parents completed the Early Trauma Inventory (ETI). All youth then collected 4 diurnal salivary cortisol samples at home across 2 consecutive weekdays. RESULTS High reported exposure to non-intentional trauma was associated with intact diurnal regulation but elevated cortisol at bedtime, physical abuse was associated with faster reactivity to acute stress, and emotional abuse was associated with delayed recovery of cortisol following acute stress. Taken together, there was a heterogeneous relationship among different indices of HPA-axis functioning and trauma subtype. DISCUSSION Different types of childhood trauma exposure are related to distinct anomalies in HPA-axis functioning. This study underscores the importance of research incorporating multiple indices of HPA-axis functioning to inform our understanding of the underlying neuroendocrine dysregulation that may later lead to stress-related psychopathology.

Abstract
OBJECTIVES This study was designed to examine escalation in repeat suicide attempts from adolescence through adulthood, as predicted by sensitization models (and reflected in increasing intent and lethality with repeat attempts, decreasing amount of time between attempts, and decreasing stress to trigger attempts). METHOD In a prospective study of 180 adolescents followed through adulthood after a psychiatric hospitalization, suicide attempts, and antecedent life events were repeatedly assessed (M = 12.6 assessments, SD = 5.1) over an average of 13 years 6 months (SD = 4 years 5 months). Multivariate logistic, multiple linear, and negative binomial regression models were used to examine patterns over time. RESULTS After age 17-18, the majority of suicide attempts were repeat attempts (i.e., made by individuals with prior suicidal behavior). Intent increased both with increasing age, and with number of prior attempts. Medical lethality increased as a function of age but not recurrent attempts. The time between successive suicide attempts decreased as a function of number of attempts. The amount of precipitating life stress was not related to attempts. CONCLUSIONS Adolescents and young adults show evidence of escalation of recurrent suicidal behavior, with increasing suicidal intent and decreasing time between successive attempts. However, evidence that sensitization processes account for this escalation was inconclusive. Effective prevention programs that reduce the likelihood of individuals attempting suicide for the first time (and entering this cycle of escalation), and relapse prevention interventions that interrupt the cycle of escalating suicidal behavior among individuals who already have made attempts are critically needed.

Abstract
Given the link between youth depression and stress exposure, efforts to identify related biomarkers have involved examinations of stress regulation systems, including the hypothalamic-pituitary-adrenal (HPA) axis. Despite these vast efforts, the underlying mechanisms at play, as well as factors that may explain heterogeneity of past findings, are not well understood. In this study, we simultaneously examined separate components of the HPA-axis response (e.g. activation intensity, peak levels, recovery) to the Socially Evaluated Cold-Pressor Test in a targeted sample of 115 youth (age 9-16), recruited to overrepresent youth with elevated symptoms of depression. Among youth who displayed a cortisol response to the task, depression symptoms were associated with higher peak responses but not greater rate of activation or recovery in boys only. Among those who did not respond to the task, depression symptoms were associated with greater cortisol levels throughout the visit in boys and girls. Results suggest that depression symptoms are associated with a more prolonged activation of the axis and impaired recovery to psychosocial stressors primarily in boys. We discussed two potential mechanistic explanations of the link between depression symptoms and the duration of activation: (1) inhibitory shift (i.e. point at which the ratio of inhibitory and excitatory input into the axis shifts from greater excitatory to greater inhibitory input) or (2) inhibitory threshold (i.e. level of cortisol exposure required to activate the axis' feedback inhibition system).

Abstract
OBJECTIVE Depression in adults is associated with risk factors for cardiovascular disease (CVD). It is unclear, however, when the association between clinical depression and cardiac risk factors develops or how early in life this association can be detected. METHODS In an ongoing study of pediatric depression, we compared CVD risk factors including smoking, obesity, physical activity level, sedentary behavior, and parental history of CVD across three samples of adolescents: probands with established histories of childhood-onset major depressive disorder (n = 210), never-depressed siblings of probands (n = 195), and controls with no history of any major psychiatric disorder (n = 161). RESULTS When assessed during adolescence, 85% of the probands were not in a major depressive episode. Nevertheless, at that assessment, probands had a higher prevalence of regular smoking (odds ratio [OR] = 12.54, 95% confidence interval [CI] = 4.36-36.12) and were less physically active than controls (OR = 0.59, CI = 0.43-0.81) and siblings (OR = 0.70, CI = 0.52-0.94) and had a higher rate of obesity than did controls (OR = 3.67, CI = 1.42-9.52). Parents of probands reported high rates of CVD (significantly higher than did parents of controls), including myocardial infarction and CVD-related hospitalization (ORs = 1.62-4.36, CIs = 1.03-15.40). Differences in CVD risk factors between probands and controls were independent of parental CVD. CONCLUSIONS Major depression in childhood is associated with an unfavorable CVD risk profile in adolescence, and risks for pediatric depression and CVD may coincide in families. Effective prevention and treatment of childhood depression may be a means to reduce the incidence of adult CVD.

Abstract
The objective of this narrative review of the literature is to describe the epidemiology, etiology, pathophysiology, diagnosis, and treatment of pediatric anxiety disorders. We aim to guide clinicians in understanding the biology of anxiety disorders and to provide general guidelines for the proper diagnoses and treatment of these conditions early in life. Anxiety disorders are prevalent, associated with a number of negative life outcomes, and currently under-recognized and under-treated. The etiology involves both genes and environmental influences modifying the neural substrate in a complex interplay. Research on pathophysiology is still in its infancy, but some brain regions, such as the amygdala and the prefrontal cortex, have been implicated in fear and anxiety. Current practice is to establish diagnosis based purely on clinical features, derived from clinical interviews with the child, parents, and teachers. Treatment is effective using medication, cognitive behavioral therapy, or a combination of both. An introduction to the neuroscience behind anxiety disorders combined with an evidence-based approach may help clinicians to understand these disorders and treat them properly in childhood.

Abstract
We examined whether the combined indices of respiratory sinus arrhythmia at rest (resting RSA) and in response to a sad film (RSA reactivity) predict effective and ineffective responses to reduce sadness (adaptive vs. maladaptive mood repair) in women with histories of juvenile-onset depression (n=74) and no history of major mental disorders (n=75). Structural equation models were used to estimate latent resting RSA, depression, and adaptive and maladaptive mood repair and to test the study hypotheses. Results indicated that combinations of resting RSA+RSA reactivity (RSA patterns) predicted maladaptive mood repair, which in turn, mediated the effects of RSA pattern on depression. Further, RSA patterns moderated the depressogenic effects of maladaptive mood repair. RSA patterns were unrelated to adaptive mood repair. Our findings suggest that mood repair is one mechanism through which physiological vulnerabilities adversely affect mental health.

Abstract
We tested the hypothesis that less effective responses during a cognitive challenge would relate to higher levels of self-reported rumination in children. The sample was 100 children (55 boys, 45 girls), aged 7 to 14 years. A portion (n=65) was at high risk for depression due to having a parent with a childhood-onset mood disorder, and 35 were a low-risk comparison group. Using an impossible puzzle task, we assessed children's responses following failure across several domains: emotions (expressed anger, sadness, and negative self-statements), performance (being off-task, the time to solve subsequent puzzles, and the number solved), and physiology (heart rate, respiratory sinus arrhythmia). Results indicated that making negative self-blaming statements during the solvable puzzles and taking more time to solve the puzzles were associated with higher levels of self-reported rumination. Our findings advance the understanding of potential correlates of children's tendency to ruminate and may have implications for children's performance on cognitive tasks.

Abstract
Childhood-onset mood disorders (COMD) are serious affective disorders with deleterious developmental sequelae including interpersonal dysfunction, psychotic symptoms and suicidal behavior. The current study examines 10 markers from two early-immediate genes for association with COMD and suicide attempt (SA) - HOMER1 and human neuronal pentraxin II (NPTX2). We examined individuals diagnosed with COMD versus matched controls, as well as individuals with COMD and a history of at least one lifetime SA versus COMD participants with no history of SA. No significant genotypic association was noted between any of the single nucleotide polymorphisms (SNPs) and COMD. Our sample yielded a nominally significant allelic association between the HOMER1 rs7713917 SNP and COMD. We report significant genotype associations between HOMER1 rs2290639 and SA , and between NPTX2 markers rs705315 and rs1681248 and SA, findings that remained statistically significant after multiple test correction. A three-way interaction was observed among HOMER1 rs4704560, rs2290639 and NPTX2 rs705318. The associations we describe for HOMER1 and NPTX2 with SA should be considered preliminary until replicated.

Abstract
This study examined the relations of school-age children's depressive symptoms, frontal EEG asymmetry, and maternal history of childhood-onset depression (COD). Participants were 73 children, 43 of whom had mothers with COD. Children's EEG was recorded at baseline and while watching happy and sad film clips. Depressive symptoms were measured using parent-report of Children's Depression Inventory. The key findings are the interaction effects between baseline and film frontal EEG asymmetry on child depressive symptoms. Specifically, relative right frontal EEG asymmetry while watching happy or sad film clip was associated with elevated depressive symptoms for children who also exhibited right frontal EEG asymmetry at baseline. Results suggest that right frontal EEG asymmetry that is consistent across situations may be an marker of depression-prone children.

Abstract
OBJECTIVES To examine whether suicidal intent and medical lethality of past suicide attempts are predictive of future attempts, the association between intent and lethality, and the consistency of these characteristics across repeated attempts among youth. METHOD Suicide attempts in a 15-year prospective study of 180 formerly psychiatrically hospitalized adolescents (M(age at hospitalization) = 14.83; 51% female; 80% Caucasian) were characterized with the Subjective Intent Rating Scale and Lethality of Attempt Rating Scale. Anderson-Gill recurrent events survival models and generalized estimating equations were used to assess predictive validity. Generalized linear models were used to examine stability of characteristics across attempts. RESULTS Neither intent nor lethality from the most recent attempt predicted future attempts. The highest level of intent and most severe lethality of attempts during the follow-up predicted subsequent attempts, but the degree to which highest intent and most severe lethality contributed to prediction after considering methods of suicide attempts, past number of attempts, or psychiatric diagnoses was mixed. Across successive attempts, there was little consistency in reported characteristics. Intent and lethality were related to each other only for attempts occurring in early adulthood. CONCLUSIONS Highest intent and lethality were better predictors of future attempts than intent and lethality of the most recent attempt. However, these characteristics should be considered as predictors only within the context of other factors. For youth, clinicians should not infer true intent from the lethality of attempts, nor assume that characteristics of future suicide attempts will be similar to those of previous attempts.

Abstract
Compromised respiratory sinus arrhythmia (RSA, i.e., low cardiac vagal control) frequently characterizes clinically depressed adults and also has been detected in infants of depressed mothers; however, its existence has not been established in older at-risk offspring. We investigated developmental patterns of RSA in a sample of 163 5- to 14-year-old children, who were either at high risk for depression (due to having a parent with a childhood-onset mood disorder) or low-risk for depression. We hypothesized that high-risk children have lower resting RSA than do low-risk children, which could reflect atypical developmental trajectories. Children's RSA was assessed during resting baseline periods on multiple occasions, typically 1-year apart. Linear growth modeling indicated a group by age interaction. Low-risk children (but not the high-risk children) exhibited a significantly increasing trajectory in resting RSA with age. Mood disorders in offspring did not account for the Group X Age interaction effect. Our study provides new evidence that children at high risk for depression have an atypical developmental trajectory of RSA across late childhood.

Abstract
This study examines how mothers with and without a history of childhood-onset depression respond to their 3-9 year-old children's emotions. Mother-child dyads included 55 offspring of mothers with a history of childhood-onset depressive disorders and 57 offspring of never-depressed mothers. Mothers with a history of childhood depression were less likely than were control mothers to respond in supportive ways to their children's negative emotions and were more likely to magnify, punish, or neglect their children's negative emotions. Magnification, neglect, and punishment of children's negative emotions were concurrently associated with children's internalizing symptoms, and neglect and punishment were associated with internalizing over a one year follow-up. Maternal neglect of children's negative emotion was positively associated with later internalizing symptoms for children who already had higher internalizing symptoms at the initial assessment. Findings suggest that atypical socialization of emotion may be one mechanism in the development of internalizing disorders.

Abstract
A working group of the European Society for the Study of Tourette Syndrome (ESSTS) has developed the first European assessment guidelines of Tourette Syndrome (TS). The available literature including national guidelines was thoroughly screened and extensively discussed in the expert group of ESSTS members. Detailed clinical assessment guidelines of tic disorders and their comorbidities in both children and adults are presented. Screening methods that might be helpful and necessary for specialists' differential diagnosis process are suggested in order to further analyse cognitive abilities, emotional functions and motor skills. Besides clinical interviews and physical examination, additional specific tools (questionnaires, checklists and neuropsychological tests) are recommended.

Abstract
Recent years have seen a growing interest into resilience to suicidality, which has been described as a perception or set of beliefs which buffer individuals from suicidality in the face of stressors. The current review extends this research by introducing the buffering hypothesis, a framework for the investigation of resilience to suicidality. The key proposal of this is that psychological resilience factors should be viewed as existing on a separate dimension to risk which acts to moderate the impact of risk on suicidality. Furthermore, like risk factors, resilience factors are bipolar, with their positive pole conferring resilience and their negative pole acting to amplify suicidality. Seventy-seven studies were identified which investigated (a) whether psychological moderators of risk exist and (b) the particular psychological constructs which may act as moderators. The review found strong support for the existence of psychological moderators and indicated a moderating impact of attributional style, perfectionism, agency and hopelessness. These findings support the buffering hypothesis and suggest that a range of psychological factors may confer resilience to suicidality. These results suggest that the identification of moderators may improve estimates of suicide risk and that the development of buffering factors could be a key focus of suicide interventions.

Abstract
BACKGROUND Oxytocin (OXT) and prolactin (PRL) are neuropeptide hormones that interact with the serotonin system and are involved in the stress response and social affiliation. In human studies, serum OXT and PRL levels have been associated with depression and related phenotypes. Our purpose was to determine if single nucleotide polymorphisms (SNPs) at the loci for OXT, PRL and their receptors, OXTR and PRLR, were associated with childhood-onset mood disorders (COMD). METHODS Using 678 families in a family-based association design, we genotyped 16 SNPs at OXT, PRL, OXTR and PRLR to test for association with COMD. RESULTS No significant associations were found for SNPs in the OXTR, PRL, or PRLR genes. Two of three SNPs 3' of the OXT gene were associated with COMD (p≤0.02), significant after spectral decomposition, but were not significant after additionally correcting for the number of genes tested. Supplementary analyses of parent-of-origin and proband sex effects for OXT SNPs by Fisher's Exact test were not significant after Bonferroni correction. CONCLUSIONS We have examined 16 OXT and PRL system gene variants, with no evidence of statistically significant association after correction for multiple tests.

Abstract
The chromosome 1p36 region was previously indicated as a locus for susceptibility to recurrent major depressive disorder based on a linkage study in a sample of 497 sib pairs. We investigated the gamma-aminobutyric acid A (GABA(A)) delta receptor subunit gene, GABRD, as a susceptibility gene to childhood-onset mood disorders (COMD) because of substantial evidence implicating GABAergic dysfunction in mood disorders and the position of this gene near the 1p36 linkage region. Using a sample consisting of 645 Hungarian families with a child/adolescent proband diagnosed with a mood disorder with the onset of the first episode before age 15, we found some evidence for the association of two polymorphisms located within the gene, rs2376805 and rs2376803, as well as significant evidence for biased transmission of the haplotypes of these two markers (global chi(2) test for haplotypes = 12.746, 3 df, P = 0.0052). Furthermore, significant evidence of association was only observed in male subjects (n = 438) when the results were analyzed by sex (chi(2) = 9.000 1 df, P = 0.003 for rs2376805). This was in contrast with the previous linkage findings, as LOD scores exceeding 3 were only in female-female pairs in that study. These findings point to the GABRD gene as a susceptibility gene for COMD; however, this gene may not explain the previous linkage finding.

Abstract
Previous studies of the relationship between anger, anger expression, and suicidal behavior have been largely cross-sectional and have yielded mixed findings. In a prospective, naturalistic study, we examined how trait anger and anger expression influenced the likelihood of suicide attempts among 180 adolescents followed for up to 13.3 years after discharge from an inpatient psychiatry unit. Results showed that higher trait anger and anger expressed outwardly over the follow-up was related to increased likelihood of suicide attempts among boys. For girls, trait anger and both the inward and outward expression of anger moderated the risk for suicide attempts associated with major depression. These results are interpreted in light of theory regarding behavioral activation and behavioral inhibition systems.

Abstract
The aim of this study was to examine the acceptability and reliability of telephone administration of the parent's version of the Children's Interview for Psychiatric Syndromes (P-ChIPS), a diagnostic interview examining 21 separate psychiatric syndromes, compared with face-to-face administration. Parents of 12 participants-seven boys and five girls-completed this preliminary study. The mean age of the children was 12.2 years (SD, 3.9 years). In comparing telephone and face-to-face administrations of the P-ChIPS, the percent agreement for each diagnosis was 75% to 100%, with an average percent agreement of 93.8% across all disorders assessed. Results of the face-to-face and telephone administration of the P-ChIPS were comparable, but this needs to be confirmed using a larger sample.

Abstract
Recent evidence supports a pathological link between heart disease and depressive symptoms, suggesting that depression is both etiologic and prognostic to heart disease. Thus, biological molecules which are at the interface between heart and mind are plausible candidate genes for depressive disorders. To investigate this line of enquiry we have investigated two genes, Endothelin 1 (EDN1) and Angiotensin-converting enzyme (ACE) in a family-based sample with childhood-onset mood disorders (COMDs). EDN1 is highly expressed in endothelium where it acts as a potent vasoconstrictor, and is also expressed in the brain where it exhibits neurotransmitter characteristics. ACE acts as a potent vasopressor, and interacts with the hypothalamic-pituitary-adrenocortical (HPA) system, which is often dysregulated in mood disorders. Furthermore, ACE has recently been found to be associated with major depression. Polymorphisms were selected to best capture the genetic variation at the two loci, and to replicate previous associations. The markers were genotyped across EDN1 and ACE in a sample comprised of 382 Hungarian nuclear families ascertained through affected probands diagnosed with a mood disorders before the age of 15. We found no evidence of association between either of these genes and COMD. Consequently, we were unable to support our hypothesis that these two genes, which are involved in both vascular and brain functions are contributing to the susceptibility to mood disorders of children/adolescents.

Abstract
Az anya-gyerek egyezést és befolyásoló tényezőit vizsgáltam depressziós és nem depressziós gyermekpopulációkban.
Célkitűzés:
Hipotézisek: a gyermek neme és életkora, az anya depressziója befolyásolja az egyezést; a depressziós gyermekek szülei alacsonyabb életminőséget jeleznek gyermekeiknél; életminőséggel kapcsolatos egyezés jobb idősebb és nem depressziós gyermekeknél.
Módszer:
Depressziós gyermekek (
N
= 354) átlagéletkora 11,69 év (sd: 2,05), nem depressziós minta (
N
= 1695) átlagéletkora 10,34 év (sd: 2,19) volt. Pszichiátriai diagnózist félig strukturált kérdőívvel, depressziós tüneteket és életminőséget önkitöltős kérdőívekkel mértem.
Eredmények:
Anya-gyerek egyezés a gyermek depressziós tüneteiről nőtt a gyermek életkorának emelkedésével. Anya-fiú beszámolók szignifikáns különbséget mutattak, anya-lány párok véleménye hasonló volt. Depressziós anyák súlyosabb tüneteket jelöltek gyermekeiknek. Depressziós gyermekek szülei alacsonyabb életminőséget gondoltak gyermekeiknél. Az egyezést befolyásolta a gyermek depressziója.
Következtetések:
A gyermek életkora, az alany pszichiátriai betegsége befolyásolja az egyezést. A gyakorlat számára fontos ezen tényezők ismerete.

Abstract
BACKGROUND Clinical depression involves persistent dysphoria, implicating impaired affect regulation or mood repair failure. However, there is comparatively little information about the mood repair repertoires of individuals with histories of clinical depression, how their repertories differ from that of never-depressed people, and whether particular types of mood repair responses differentially contribute to depression risk. METHOD Adult probands who had childhood-onset depressive disorder (n=215) and controls with no history of major mental disorder (n=122) reported which specific (cognitive, behavioral, interpersonal and somatic-sensory) responses they typically deploy when experiencing sad affect, including responses known to appropriately attenuate dysphoria ('adaptive' responses) and those known to exacerbate dysphoria in the short or long run ('maladaptive' responses). Subjects were longitudinally followed and evaluated. RESULTS Remitted probands and probands in depressive episodes both reported a greater number of maladaptive responses and fewer adaptive responses to their own sadness than did controls, although probands did not have an absolute deficiency of adaptive responses. Maladaptive (but not adaptive) mood repair responses predicted future increases in depression symptoms and an increased probability of a recurrent depressive episode among probands (even after controlling for several clinical predictors of course). Post-hoc analyses revealed that maladaptive non-cognitive and maladaptive cognitive mood repair response sets each predicted depression outcomes. CONCLUSIONS Individuals with past and present episodes of depressive disorder report an array of cognitive and non-cognitive responses to their own sadness that are likely to exacerbate that affect, and this pattern predicts a worse course of the disorder.

Abstract
Studies in both animals and humans advocate a role for the vasopressin (AVP) system in the aetiology of depressive symptoms. Attention has particularly focused on the role of AVP in the overactivation of the hypothalamic-pituitary-adrenal (HPA)-axis in mood disorders. Elevated AVP plasma levels have been found in mood disorder patients, which are often positively correlated with the severity of symptoms. We recently reported an association between childhood-onset mood disorders (COMD) and polymorphisms in the receptor responsible for the AVP-mediated activation of the HPA-axis (AVPR1B). As genetic variation in the vasopressinergic system could provide a mechanism to explain the endocrine alterations observed in mood disorders, we investigated other genes in this system. The gene encoding AVP is the strongest candidate, particularly as genetic variation in this gene in rodents is associated with anxiety-related behaviours. Six single-nucleotide polymorphisms (SNPs) were genotyped across the AVP gene in a sample comprised of 586 Hungarian nuclear families ascertained through affected probands with a diagnosis of COMD. In addition, AVP coding and putative regulatory regions were screened for mutations using denaturing high-performance liquid chromatography. One SNP, 3' to the AVP, gene reached significance (P = 0.03), as did the overtransmission of a five-marker haplotype with a frequency of 22% (P = 0.0001). The subsequent mutation screen failed to identify any putative functional polymorphisms. The outcome of this study, combined with our previous association between COMD and AVPR1B, implicates genetic variation in vasopressinergic genes in mediating vulnerability to COMD.

Abstract
Depressive disorders are highly heterogeneous psychiatric disorders involving deficits to cognitive, psychomotor, and emotional processing. Considerable evidence links disruption to the hypothalamic-pituitary-adrenal (HPA) axis to the etiology of depression, with specific deficits reported in glucocorticoid receptor (GR)-mediated negative feedback. Given the role of GR-mediated negative feedback in mediating response to stress, and the clear link between stress and depression, it is plausible that polymorphisms in the GR gene (NR3C1) act to increase susceptibility. Maternal behavior in rats epigenetically alters a NGF1-A transcription factor binding-site in the promoter region of the GR gene, providing a mechanism by which environmental cues can regulate GR expression and thus response to stress. The analogous region of the human GR gene (NR3C1) has not been studied, but it is possible that polymorphisms in this region may alter the binding of transcription factors known to regulate GR expression. In this study, we have performed bioinformatic analyses on the promoter region of NR3C1 to identify conserved promoter sequences and predicted transcription factor binding sites. These regions were screened with denaturing high-performance liquid chromatography (DHPLC) and direct re-sequencing, and several novel polymorphic variants were identified. We genotyped nine polymorphisms across NR3C1 in a large sample of Hungarian nuclear families ascertained through affected probands with a diagnosis of childhood-onset mood disorders (COMD). Single-marker analysis provided little evidence for an association of this gene with COMD, but multi-marker analysis across a region of high linkage disequilibrium revealed modest evidence for the biased transmission of several haplotypes.

Abstract
The purpose of this prospective, naturalistic study was to examine the relationships between suicide attempts and contemporaneous psychiatric disorders, and developmental changes in these relationships from adolescence to young adulthood. The sample consisted of 180 adolescents, 12-19 years of age at hospitalization, repeatedly assessed for up to 13 years (n = 1,825 assessments). Semistructured psychiatric diagnostic instruments were administered at repeated assessments to assess psychiatric disorders and suicide attempts. After controlling for demographic variables and prehospitalization suicide attempts, most contemporaneous psychiatric disorders (major depressive disorder [MDD], dysthymic disorder, generalized anxiety disorder [GAD], panic disorder, attention-deficit/hyperactivity disorder [AD/HD], conduct disorder, and substance use disorder [SUD]) were related to increased risk of attempts. The relationship between suicide attempts and MDD, GAD, AD/HD, and SUD strengthened as participants got older. MDD, dysthymic disorder, GAD, and panic disorder were more commonly associated with repeat than 1st-time suicide attempts. In sum, most major psychiatric disorders are associated with increased risk for suicide attempts, but the strength of the relationships between these disorders and attempts changes over the course of development.

Abstract
We examined respiratory sinus arrhythmia (RSA), emotion regulation (ER), and prospective depressive symptoms in children at risk for depression and controls. Of the 65 children (35 boys; 5-13 years) in the sample, 39 had a parent with childhood-onset mood disorder and 26 had a parent with no history of major psychiatric disorder. RSA during pre- and post-film baselines and RSA reactivity to sad film clip were measured. Later, children's ER responses (focusing on sad/distressing affect) were assessed using a parent-reported questionnaire, and depressive symptoms were measured via clinical ratings. Results indicated that, compared to the initial baseline, a greater decrease in RSA (i.e., more vagal withdrawal) in response to the sad film clip predicted more adaptive ER responses and lower levels of clinician-rated depressive symptoms. However, tests for ER as a mediator of the association between RSA reactivity and depressive symptoms were precluded because maladaptive, but not adaptive, ER was associated with depressive symptoms. Overall, results suggest that cardiac vagal withdrawal (a greater decrease in RSA) in response to an emotional stimulus reflects more adaptive parasympathetic activity, which could facilitate children's ability to effectively manage their sadness and distress and predict lower risk of depressive symptoms over time.
