The Behavior and Mind Health (BeMIND) study: Methods, design and baseline sample characteristics of a cohort study among adolescents and young adults

Subclinical patterns of disordered eating behaviors in the daily life of adolescents and young adults from the general population

BACKGROUND

Disordered eating behaviors (DEBs), a risk factor for the development of eating disorders (EDs), are prevalent in young people and different DEBs frequently co-occur. Previous studies on DEB-patterns have largely used traditional retrospective questionnaires to assess DEBs. In addition, most previous studies did not specifically exclude individuals with clinical EDs, which limits current knowledge concerning purely subclinical patterns of DEBs. In the present study, we aimed to explore phenotypes and group sizes of subclinical patterns of DEBs reported in everyday life via smartphone-based ecological momentary assessment (EMA) in adolescents and young adults from the general population without lifetime EDs. In secondary analyses, we further aimed to investigate whether DEB-patterns would be associated with additional previously identified risk factors for ED-development.

METHODS

EMA was conducted in a community sample of 14-21-year-olds from Dresden, Germany, over four days for up to eight times a day and covered engagement in four DEBs: skipping eating, restrained eating, eating large amounts of food, and loss-of-control eating. Data were analyzed from N = 966 individuals without lifetime EDs with an EMA compliance rate of at least 50% (81.9% of the total sample; average compliance: 84.6%). Latent profile analyses were performed to identify subclinical patterns of DEBs, stratified by sex. Associations between symptomatic profiles and ED-risk factors were tested via regression analyses.

RESULTS

Based on theoretical deliberations, statistical indices, interpretability, and parsimony, a three-profile solution, namely no DEBs, high-mixed DEBs, and low-mixed DEBs, was selected for both sexes. Both symptomatic profiles in both sexes were associated with more unfavorable manifestations in additional ED risk factors compared to the no DEBs profile, with the highest number of associations being observed in the female high-mixed profile.

CONCLUSIONS

The present findings suggest that problematic manifestations of DEBs in young people may occur even in the absence of an ED diagnosis and that they are associated with additional risk factors for EDs, warranting increased efforts in targeted prevention, early identification and intervention in order to counteract symptom progression.

Tension and disordered eating behaviors in the daily lives of adolescents and young adults from the general population: Associations and moderating role of trait emotion regulation

Experiences of tension and difficulties in emotion regulation have been linked to eating pathology in clinical samples and are targeted in respective treatment approaches. The present study aimed to investigate the impact of tension on engagement in disordered eating behaviors (DEBs) and potential moderating effects of trait emotion regulation in young people from the general population. A subsample of 971 adolescents and young adults from an epidemiological cohort study reported on levels of tension and four different DEBs (skipping eating, restrained eating, eating large amounts of food, loss-of-control-eating) via ecological momentary assessment (EMA), as well as on trait emotion regulation via questionnaire. In multilevel models, momentary tension did not predict levels of subsequent DEBs. However, higher average levels of tension across the EMA period predicted higher levels of all DEBs. No interactions with emotion regulation emerged. Individuals experiencing overall higher levels of tension appear to be more prone to engaging in DEBs.

Sociodemographic, psychological, and clinical characteristics associated with health service (non-)use for mental disorders in adolescents and young adults from the general population

Most adolescents and young adults who experience psychological distress do not seek professional help. This study aims to enhance the understanding of sociodemographic, psychological, and clinical characteristics associated with the underuse of health services by adolescents and young adults with mental disorders. Data from a cross-sectional, epidemiological study with a population-based sample (N = 1180 participants, 14-21 years old) were used. Participants completed a fully standardized, computer-assisted diagnostic interview (DIA-X-5/D-CIDI) administered by trained clinical interviewers to assess lifetime mental disorders according to DSM-5 as well as lifetime health service use for mental health problems, and completed self-report questionnaires to assess various psychological variables (e.g., stigma). Predictors of health service use were examined using univariate and multiple logistic regression analyses, data were weighted for age and sex to improve representativeness Of n = 597 participants with any lifetime mental disorder, 32.4% [95% CI 28.4; 36.7] had ever used any health services because of a mental health, psychosomatic, or substance use problem. Even less had received psychotherapeutic or pharmacological treatment (Cognitive Behavioral Therapy: 12.1% [9.5; 15.2]; other psychotherapy: 10.7% [8.4; 13.7]; medication: 5.4% [3.7; 7.8]). High education was associated with less health service use (low/ middle/ other vs. high education: 53.8% vs. 26.9%; OR = 0.26, p < .001). In the multiple regression model, stigma toward mental disorders was the single psychological variable associated with a reduced likelihood of using health services (OR = 0.69 [0.52; 0.90], p < .01). These findings draw attention to the treatment gap for mental disorders during adolescence and highlight related factors to be addressed in public health contexts.

Social Interactions in Everyday Life of Socially Anxious Adolescents: Effects on Mental State, Anxiety, and Depression

Unfavorable interpersonal behavior in social anxiety disorder (SAD) contributes to the maintenance of the disorder and may also be related to the development of secondary depression. Since there is limited research on daily life behavior in SAD, this study aimed to describe social interaction behavior and analyze the effect of positive interactions on depression, anxiety, and mental state. Data were obtained from the Behavior and Mind Health study (11/2015-12/2016), an epidemiological cohort study of adolescents and young adults (n = 1,180, aged 14-21 years) from Dresden, Germany. Interpersonal behavior, current mental state, anxiety, and depression were assessed eight times per day over four days using smartphone-based ecological momentary assessments. The analyzed subsample consisted of n = 723 participants, comparing 12-month SAD (n = 60) and healthy controls (HC; n = 663). The interaction behavior of participants with SAD did not differ substantially from that of HC in terms of frequency of social interactions, type of interaction partner, and time spent communicating, although they reported fewer real-life interaction partners (SAD: M = 2.49, SD = 4.78; HC: M = 3.18, SD = 6.43; F(17,044) = 23.92, p < 0.001). When comparing mental state, anxiety, and depression after interactions with familiar people to no interaction, no differences were found between SAD and HC. However, interactions with unfamiliar people negatively affected depressive symptoms in individuals with SAD (b = 0.53; SE = 0.25; 95%CI: 0.04-1.03; p = 0.036). In adolescents with SAD, social situations with unfamiliar people seem to be processed in a dysfunctional way, contributing to increased depressive mood in everyday life. This is particularly interesting given the high rate of secondary depression in SAD.

Addressing help-seeking, stigma and risk factors for suicidality in secondary schools: short-term and mid-term effects of the HEYLiFE suicide prevention program in a randomized controlled trial

BACKGROUND

Suicidal ideation and suicide attempts present a serious public health concern among adolescents and young adults. School-based suicide prevention programs are a key tool for addressing this problem. However, more research is necessary to assess their effectiveness, acceptability, and safety. In response, the HEYLiFE suicide prevention program was developed to enhance help-seeking, reduce stigma towards suicidal peers and diminish risk factors for suicidality. This article presents the evaluation findings of the HEYLiFE program in German secondary schools.

METHODS

We conducted a randomized-controlled trial measuring short-term pre-post within-group effects in the intervention group only and mid-term effects at 6-months-follow-up compared to a waitlist-control group. Schools were assigned randomly to the intervention or control group (no blinding). We recruited students ≥12 years of age. Primary outcomes were knowledge about suicidality, attitudes towards suicidality, stigma towards a suicidal peer, help-seeking intentions and behaviours, risk factors for suicidality. The data was analysed with linear mixed models and generalized linear mixed models.

RESULTS

A total of N = 745 students participated (n = 353 intervention group, n = 392 control group). We observed favourable short-term effects on knowledge, attitudes towards suicidality and fear towards a suicidal peer. Unexpectedly, the program also led to an increase in desire for social distance and a decrease in prosocial emotions towards a suicidal peer. The mid-term effects of the program were exclusively favourable, resulting in enhanced attitudes towards help-seeking while protecting from a sharper rise in risk-factors for suicidality and from an increase in social distance. The program had more favourable effects on females and on students aged >13 years. The program was well-received by the students, and no serious adverse events were reported.

CONCLUSIONS

These findings demonstrate the effectiveness of the HEYLiFE universal suicide prevention program in addressing variables associated with suicidal ideation and suicide attempts among adolescents on the mid-term. The short-term negative effects on stigma and more negative effects on males should be addressed in the future. Future evaluation studies should examine its effects on suicidality and its effectiveness within populations at high risk.

TRIAL REGISTRATION

The study was preregistered in the German Clinical Trials Register (registration number: DRKS00017045; registration date: 02/04/2019).

The Association Between Childhood Maltreatment and Body (dis)satisfaction in Adolescents and Young Adults from the General Population

Adolescents with a history of childhood maltreatment are vulnerable to body dissatisfaction and associated psychopathology such as eating disorders. The aim of this study was to expand the understanding of the association between childhood maltreatment and body dissatisfaction in adolescents and young adults. In an epidemiological cohort study, N = 1,001 participants aged 14-21 years from Dresden, Germany, completed self-report measures on childhood maltreatment, body image, and self-esteem. Lifetime mental disorders were assessed in standardized clinical interviews. Data analyses included multiple regression and mediation analyses. More than one-third of the participants reported experiences of childhood maltreatment (37.4%), in which emotional neglect and abuse were the most frequent subtypes. Individuals with a history of childhood maltreatment showed significantly less satisfaction with their physical appearance than participants without such adverse experiences. In a single mediator model, self-esteem emerged as potential mediator in the association between child maltreatment and body (dis)satisfaction. Experiences of childhood maltreatment may be considered as risk factor for the development of body dissatisfaction in adolescents, and the role of potential mediator variables such as self-esteem warrants further prospective research.

The Future Proofing Study: Design, methods and baseline characteristics of a prospective cohort study of the mental health of Australian adolescents

OBJECTIVES

The Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort.

METHODS

The FPS is an Australian school-based prospective cohort study with an embedded cluster-randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self-report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years.

RESULTS

The baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05).

CONCLUSIONS

This paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence.

Hair androgen concentrations and depressive disorders in adolescents from the general population

Although the link between androgens and depression is well established in adults, the effects of cofactors on this association are less clearly understood, particularly in youth. Epidemiological cohort study of adolescents in Dresden, Germany. Analyses comprised data of 985 individuals assessed at baseline and of 512 individuals at 1-year follow-up. We investigated multivariable regression models for cross-sectional and longitudinal associations of hair testosterone, dehydroepiandrosterone (DHEA), and their cortisol ratios with 12-month diagnoses of major depressive disorder (MDD) and MDD without any anxiety disorder assessed with standardized diagnostic interview (DIA-X-5), and with dimensional depression scores (PHQ-9, PROMIS), separately for males and females. The potential moderating effect of social support was determined. Cross-sectional analyses yielded inverse associations of testosterone and DHEA with MDD and MDD without any anxiety disorders in males. In cross-sectional and longitudinal analyses, baseline ratio cortisol/DHEA was significantly, inversely associated to PROMIS-depression in males. Only cross-sectional associations for ratio cortisol/DHEA and PROMIS-depression remained significant after Bonferroni-Holm correction. No robust associations were observed in female participants. Social support exerted no consistent moderating effect on the investigated association. The present observational cohort study showed no consistent association of hair androgen concentrations with depressive disorders in adolescents. However, findings provide some support for the association between the cortisol/DHEA ratio and depression in males. Longitudinal research designs in large samples are needed to understand the interplay between androgens, depression, and developmental and social factors in youth.

Temporal associations between experiential avoidance and disordered eating behaviors in adolescents and young adults: findings from an epidemiological cohort study with ecological momentary assessment

PURPOSE

Previous studies linking experiential avoidance (EA) and eating pathology have largely relied on single measurements based on traditional retrospective questionnaires. Taking advantage of available repeated assessments of EA and disordered eating behaviors (DEBs) in the everyday lives of young people from an epidemiological cohort, we aimed to investigate ecologically valid temporal associations between these constructs.

METHODS

A random population sample of N = 1180 14-21-year-olds from Dresden, Germany, participated at baseline (2015/2016). As part of smartphone-based ecological momentary assessment (EMA), participants reported on engagement in EA and four DEBs (skipping eating, eating large amounts of food, loss-of-control eating, and restrained eating) up to eight times per day for four days. Multilevel modeling of concurrent and time-lagged associations between EA and DEBs, was conducted among those with at least 50% EMA-compliance (n = 1069).

RESULTS

EA was associated with higher concurrent levels of all four types of concurrent DEBs. In addition, EA significantly predicted subsequent levels of restrained eating. Only loss-of-control eating significantly predicted subsequent EA, and this effect depended on the timespan between consecutive assessments. When this timespan was short, higher Loss-of-control eating predicted lower subsequent EA, while it predicted higher subsequent EA when the timespan was longer.

CONCLUSION

The present findings suggest that EA is temporally closely linked to greater engagement in DEBs, supporting theoretical assumptions that DEBs may serve an attempted avoidance function in the context of unpleasant inner experiences. Future studies may benefit from examining samples with more pronounced eating pathology.

LEVEL OF EVIDENCE

Level IV: Evidence obtained from multiple time series with or without the intervention, such as case studies.

Dynamics of affect, cognition and behavior in a general population sample of adolescents and young adults with current and remitted anxiety disorders: An Ecological Momentary Assessment study

BACKGROUND

Measures of dynamic changes in affect/emotions (variability, instability, inertia) have been linked to anxiety disorders (AD). We examine dynamics in affect, cognition and behavior in youth with current and remitted AD.

METHODS

Mental disorders were assessed in a general population sample (N = 1180, age 14-21; Dresden, Germany) using standardized interview. Ecological Momentary Assessment of real-life affect, cognition and behavior took place eight times/day for four days.

RESULTS

Individuals with current AD (n = 65) compared to healthy controls (HC, n = 531) revealed heightened variability of anxious and manic symptomatology, experiential avoidance, optimism and positive thoughts. Remitted AD (n = 52) showed lower variability of anxious and manic symptomatology and positive thoughts compared to current AD, while no differences were found compared to HC. Current AD and HC differed significantly in instability. Remitted AD showed lower instability of all constructs except for anger than current AD, and higher instability on all constructs except for positive and negative thoughts compared to HC. Current AD showed higher inertia of anger and negative thoughts than HC, and less inertia of positive thoughts than remitted AD.

DISCUSSION

AD in youths is particularly linked to higher variability and instability of intertwined emotion-related experiences that partly persist after remission, informing emotion regulation models and interventions.

Social anxiety in adolescents and young adults from the general population: an epidemiological characterization of fear and avoidance in different social situations

Social Anxiety Disorder (SAD) and, more generally, social fears are common in young people. Although avoidance behaviors are known to be an important maintaining factor of social anxiety, little is known about the severity and occurrence of avoidance behaviors in young people from the general population, hampering approaches for early identification and intervention. Symptoms, syndromes, and diagnoses of DSM-5 mental disorders including SAD were assessed in a random population-based sample of 14-21-year-olds (n = 1,180) from Dresden, Germany, in 2015/2016 using a standardized diagnostic interview (DIA-X-5/D-CIDI). An adapted version of the Liebowitz Social Anxiety Scale was used to ascertain the extent of social fears and avoidance. Diagnostic criteria for lifetime SAD were met by n = 82 participants, resulting in a weighted lifetime prevalence of 6.6%. Social anxiety was predominantly reported for test situations and when speaking or performing in front of others. Avoidance was most prevalent in the latter situations. On average, anxiety and avoidance first occurred at ages 11 and 12, respectively, with avoidance occurring in most cases either at about the same age as anxiety or slightly later. In the total sample, lifetime prevalence for most DSM-5 disorders increased with the severity of social anxiety and avoidance. Results underline the need for preventive or early intervention efforts especially regarding test anxiety and fear and avoidance of speaking in front of others. These situations are particularly relevant in youth. Avoidance behaviors may also be discussed as diagnostic marker for early case identification.

5-HTT genotype and inertia of negative affect in adolescents and young adults from the general population

The study aims to replicate the previous found association of 5-HTTLPR and inertia of negative affect in daily life of adolescents and young adults. Data of 877 adolescents (aged 14–21 years) of the Behavior and Mind Health (BeMIND) study (epidemiological cohort study, Dresden, Germany) were genotyped for 5-HTTLPR/rs25531, grouped into SS/SL_G/SL_A/L_GL_A/L_GL_G vs. L_AL_A, and provided ratings on negative affect items, depression and anxiety (Patient-Reported Outcomes Measurement Information System) eight times a day over 4 days. Multilevel regression models did not reveal an association of 5-HTTLPR genotype and inertia of negative affect, nor associations with inertia of anxiety or depression. Inertia of negative affect seems not to be a psychological mechanism through which 5-HTTLPR acts on psychopathology.

Anxiety disorders among adolescents and young adults: Prevalence and mental health care service utilization in a regional epidemiological study in Germany

BACKGROUND

Anxiety disorders are among the most prevalent mental disorders. While it is known that a majority of individuals with anxiety disorders remains untreated, actual treatment rates for adolescents and young adults in Germany remain largely unknown.

METHODS

As part of the Behavior and Mind Health (BeMIND) study, examining a random community sample of 14-21-year-olds (Dresden; Germany; N = 1,180), the lifetime prevalence for DSM-5 anxiety disorders and lifetime service utilization rates were determined by a standardized interview (DIA-X-5/CIDI).

RESULTS

In the present sample, 23.3 % of adolescents and young adults fulfilled DSM-5 criteria for at least one lifetime anxiety disorder. Of those, 39.1 % used any health care services, most frequently they visited an outpatient psychotherapist/psychologist (23.0 %). Individuals with agoraphobia were most likely to use any in- or outpatient specialized service (64.8 %), while individuals with a specific phobia were least likely (22.3 %). Having a comorbid disorder or being female increased the likelihood of seeking help.

CONCLUSION

The results showed that approximately 2/3 of adolescents and young adults suffering from an anxiety disorder did not seek help and only few report contacts with a psychotherapist. Given the adverse long-term consequences of anxiety disorders, these findings suggest to improve efforts on increasing intervention awareness and treatment possibilities for these individuals.

Evidence for the association between physiological and emotional states in adolescents and young adults without psychopathology under ecologically valid conditions

Well-powered studies on the physiological concomitants underlying affect and its regulation during emerging adulthood are warranted to provide novel insight into mental health. The association between autonomic nervous system activity and emotional states occurring under natural conditions in daily life was investigated in individuals (N = 549, age 14-21, females 45.6%) without any lifetime mental disorder from an epidemiological cohort study in Germany. Using ecological momentary assessment, mood and optimism/pessimism were assessed over 4 days simultaneously with continuous heart rate monitoring. Lower vagal activity was found in mood states accompanied by high arousal (wakefulness, mania) and greater vagal activity in mood states with low arousal (calmness, pessimism). Findings illustrate important associations between autonomic nervous system activity and mood in youth under ecologically valid conditions. Vagal activity presents a prominent pathway by which mood may influence physiological function or vice versa. In contrast to commonly performed laboratory assessments, the ambulatory assessment in participants' daily life allows an application of the results to the field.

Associations of saliva cortisol and hair cortisol with generalized anxiety, social anxiety, and major depressive disorder: An epidemiological cohort study in adolescents and young adults

OBJECTIVES

Most of the observed associations of generalized anxiety disorder (GAD), social anxiety disorder (SAD) and major depressive disorder (MDD) with cortisol concentrations came from clinical and adult study samples, with inconsistent findings, partly due to method variance. We examined cross-sectional and longitudinal associations between GAD, SAD and MDD with saliva and hair cortisol as well as hair cortisol change in a population-based sample of adolescents and young adults, considering relevant co-factors.

DESIGN

Epidemiological cohort study in Dresden, Germany. Data of 1050 individuals (mean age: 17.2 years) assessed at baseline (11/2015-12/2016) and of 605 individuals assessed at 1-year follow-up (FU1) are used.

METHODS

Multivariable regression models were implemented to assess cross-sectional and longitudinal associations of DSM-5 defined 12-month diagnoses of GAD, SAD, and MDD, with short-term (saliva cortisol: cortisol awakening response (CAR) and area under the curve (AUC) as total cortisol) and long-term (hair cortisol) cortisol indices. Multivariable models were adjusted for age or "tanner" stage, waist circumference, tobacco and alcohol consumption, physical inactivity, and hair cortisol dependent confounder. Sex-specific analyses were additionally conducted.

RESULTS

Cross-sectional analyses revealed positive associations between SAD and baseline saliva cortisol in multivariable models (CAR: β-coefficient: 0.12; 95% CI: 0.01; 0.23) but could not be confirmed after adjusting for "tanner" stage or comorbid depression. Cross-sectional analyses concerning GAD and MDD in the full baseline sample yielded no significant associations. Sex-specific linear models revealed a significant inverse cross-sectional association between MDD (β-coefficient: - 2.21; 95% CI: - 3.64; - 0.79) as well as SAD (β-coefficient: - 2.21; 95% CI: - 4.03; - 0.38) with baseline hair cortisol in males, but not in females. In longitudinal analyses, no significant associations were found in the fully adjusted model, except for a positive association between hair cortisol change between baseline and FU1 and FU1-SAD (OR: 1.07; 95% CI: 1.02; 1.12).

CONCLUSIONS

Results confirmed sex-specificity and the role of pubertal development in the association between cortisol with SAD and MDD, while no association emerged regarding cortisol and GAD. Future research in adolescents focusing on the role of cortisol in the pathogenesis of anxiety and depressive disorders would benefit from considering factors like sex-specificity and puberty development as well as comorbidity.

How current and past anxiety disorders affect daily life in adolescents and young adults from the general population-An epidemiological study with ecological momentary assessment

BACKGROUND

Prior research indicated, based on retrospective assessments of symptomatology, that 25% of individuals with "remitted" anxiety disorders (AD) experience a relapse. The present study used ecological momentary assessment (EMA) to examine how ADs affect everyday life among community adolescents and young adults with current or remitted AD compared to healthy controls and to each other.

METHODS

Data come from the baseline assessment of the epidemiological Behavior and Mind Health study, conducted in Dresden (Germany) from 11/2015-12/2016. The sub-sample analyzed (n = 648, age 14-21) consisted of 65 participants with current DSM-5 AD-diagnosis, 52 participants with lifetime AD-diagnosis but not within the last 6 months (remitted), and 531 healthy controls (no psychopathology; healthy controls [HC]). EMA of various constructs took place 8 times a day for 4 days.

RESULTS

The highest levels of symptoms were reported by those with current AD, followed by remitted AD and HC. Regression analyses revealed significantly worse mood, self-efficacy, quality of life and sleep-quality and more experiential avoidance, stress, negative thoughts and pessimism in remitted and current AD compared to HC. Current AD additional differed significantly from HC in optimism and positive thoughts. Furthermore, individuals with remitted AD without comorbidities differed significantly from HC on five out of 16 constructs.

CONCLUSION

Not only current but also remitted AD is associated with diverse negative experiences in everyday life, which cannot merely be explained by comorbidities. As the remaining burden and impairment in individuals with remitted AD might contribute to relapse, interventions might be targeted to improve mental health.

The interaction of 5-HTT variation, recent stress, and resilience on current anxiety levels in adolescents and young adults from the general population

BACKGROUND

Previous work on gene-environment (GxE) interplay concerning anxiety has focused on the interaction of 5-HTTLPR with childhood adversities or traumatic events whereas the impact of recent stressors is understudied, as is the integration of resilience. The current study aimed to investigate the interactive effect of 5-HTTLPR and recent stress on anxiety in adolescents considering resilience as buffer of a GxE risk constellation.

METHOD

In a random population-based sample of 14-21 years old from Dresden, Germany, (N = 1180; genotyped = 942) recent stress (Daily Hassles [DH] Scale, Perceived Stress Scale, Screening Scale of the Trier Inventory for the Assessment of Chronic Stress), resilience (Connor-Davidson resilience scale) and anxiety (Patient Reported Outcome Measurement Information System Anxiety Short Form) were assessed via questionnaire in 2015 or 2016.

RESULTS

Fractional regression models revealed that resilience interacted with recent stress in form of DH as well as recent chronic stress and 5-HTTLPR regarding anxiety. Participants carrying the more active L_A L_A genotype reported consistently higher levels of anxiety when experiencing more DH or more recent chronic stress and having low levels of resilience. When the resilience scores were high, L_A L_A carriers reported the lowest anxiety scores despite DH or recent chronic stress.

CONCLUSION

Findings revealed an interactive relationship between 5-HTTLPR genotype and recent stress suggesting resilience to function as an additional dimension buffering the impact of a GxE risk constellation. Early interventions to build resilience may be useful to prevent an escalation of distress and associated unfavorable health outcomes.

Non-suicidal self-injury and its co-occurrence with suicidal behavior: An epidemiological-study among adolescents and young adults

OBJECTIVE

Non-suicidal self-injury (NSSI) comprising thoughts and behaviors is common and often co-occurring with suicidal behavior like ideation, plan, and attempt. As limited data are available for adolescents and young adults, this study aims to present prevalence estimates for lifetime NSSI, its co-occurrence with suicidal behavior, conditional probabilities and their association with socio-demographic characteristics, severity characteristics of suicidal behavior, and health service utilization.

METHOD

The epidemiological Behavior and Mind Health (BeMIND) study assessed in 2015/16 a random-community sample of N = 1180 aged 14-21 years from Dresden, Germany, regarding lifetime NSSI via self-administered questionnaire and suicidal behaviors via standardized interview.

RESULTS

Any lifetime NSSI was reported by 19.3% (thoughts: 18.0%, behaviors: 13.6%) of the sample with higher prevalence in females (OR = 2.7, 95% CI 1.9-3.8, P < 0.001). Lifetime prevalence of co-occurring NSSI and suicidal behavior was 7.7%. Females had a 3.3- to 8.8-fold odds of co-occurrence than males. Among those with any NSSI, 39.6% endorsed suicidal behavior, and 66.3% of those with any suicidal behavior reported NSSI. 42.3% of those with any NSSI reported to have used mental healthcare services at any time during their life with higher rates in those with co-occurring suicidal behavior (62.3%).

CONCLUSION

Non-suicidal self-injury and co-occurring suicidal behavior is common in adolescents and young adults-especially females. The limited utilization of mental healthcare services underpins the need for improving recognition of NSSI and suicidal behavior as well as the accessibility of mental healthcare services during adolescence and emerging adulthood.

The Behavior and Mind Health (BeMIND) study: Methods, design and baseline sample characteristics of a cohort study among adolescents and young adults

OBJECTIVES

The Behavior and Mind Health (BeMIND) study is a population-based cohort study of adolescents and young adults from Dresden, Germany. The aim is to investigate psychological and behavioral factors linked to a range of mental disorders and health behaviors and their interaction with social-environmental and genetic/biologic factors.

METHODS

A random sample of 14-21 year olds was drawn from the population registry in 2015. The baseline investigation was completed 11/2015-12/2016 (N = 1,180). Assessments include standardized diagnostic interview, cognitive-affective tasks, questionnaires, biosamples, and ecologic momentary assessment in real life with combined actigraphic/geographic monitoring. In the family study component, parents completed similar assessments and provided information on child's early development.

RESULTS

The participation rate (minimum response proportion) was 21.7%; the cooperation rate was 43.4%. Acceptance and completion of study components were high. General health data indicate that more than 80% reported no or only mild impairment due to mental or somatic health problems in the past year; about 20% ever sought treatment for mental health problems or chronic somatic illnesses, respectively.

CONCLUSIONS

Data from BeMIND baseline and follow-up investigations will provide novel insights into contributors to health and disease as adolescents grow into adulthood.
