Protective factors against depression during the transition from adolescence to adulthood: findings from a national Canadian cohort

Peer popularity and self-discipline as protective factors against depressive symptoms in Chinese adolescents: Do boys and girls benefit equally?

The current study examined the concurrent and longitudinal protective effects of peer popularity and self-discipline (control, planning, and the ability to prioritize important things) against depressive symptoms among adolescents. We used multilevel modeling to examine the data of 1676 adolescents aged 12-15 years from the China Family Panel Studies (CFPS) survey, a large-scale panel survey with a nationally representative sample. Results showed that both peer popularity and self-discipline predicted lower levels of depressive symptoms measured concurrently. The buffering effect of self-discipline against concurrent depressive symptoms was stronger for girls than for boys, especially in middle adolescence. Peer popularity additionally predicted lower levels of depressive symptoms 4 years later, and this effect was stronger for girls than for boys. These patterns of results were maintained after controlling for self-rated physical health and society-level factors. We discuss these findings against the background of distinct traditional gender roles.

Do yoga and meditation moderate the relationship between negative life events and depressive symptoms? Analysis of a national cross-sectional survey of Australian women

Objectives

This study aims to examine the role of yoga/meditation in the relationship between negative life events, stress and depression.

Methods

The Australian Longitudinal Study on Women's Health (ALSWH) surveyed 7,186 women aged 36-43 years (mean age 39.2 years; 57.2% university degree) in 2015. Mediation and moderation analyses were conducted to examine whether yoga/meditation practice moderated those relationships.

Results

Yoga/meditation was practiced by 27.5% of participants, 33.2% reported negative life events in the past 12 months, and 24% had clinical depression. Perceived stress partially mediated the association between negative life events and depressive symptoms (B = 6.28; 95%CI 5.65; 6.92). Social support (B = -0.38; 95%CI -0.54; -0.23) and optimism (B = -0.25;95%CI -0.31; -0.18) moderated the association between stress and depressive symptoms. Yoga/meditation practice moderated the direct association between negative life events and depressive symptoms (B = -0.92; 95%CI -1.67; -0.18).

Conclusion

Yoga/meditation use was a significant moderator of the relationship between negative life events and depression. Yoga/mediation use did not act via reducing perceived stress, but instead was found to dampen the influence of negative life events on depression directly. More research on how yoga has an impact on depression is warranted.

Resilience and self-compassion among persons with depressive disorders: Prerequisite for a positive mental health approach

Background

Treatment gap for common mental health problems, especially of the depressive disorders is consequential in developing countries like India. Positive mental health domains like resilience and self-compassion have been long hailed as protective factors against depression and viable for use in therapeutic aspects. The objectives were to find an association between resilience, self-compassion, and depression.

Methods

The study was conducted using a cross-sectional design among 75 respondents who were seeking treatment for major depressive disorders from a tertiary care center during the second wave of COVID-19. Three scales were administered online, namely Beck's Depression Inventory-II (BDI-II), Connor Davidson Resilience Scale (CD RISC-25), and Self-Compassion Scale-Short Form (SCS-SF). Spearman's rank correlation test, Chi-square with Fisher's exact test, and Kruskal Wallis H test were used to study the relationships and differences in average scores with respect to the severity of depression.

Results

Most of the respondents had moderate depressive features along with moderately high levels of resilience (CD RISC 25) and self-compassion (SCS-SF) scores. Resilience and self-compassion were found to have no significant relationship with respect to the severity of depression. There was a weakly positive correlation between resilience and self-compassion among those with moderate and severe depression.

Conclusion

Since the individuals with depression had higher scores on resilience and self-compassion, the levels of depression remained at moderate levels of severity despite the devastating impact of the second wave of COVID-19 in the Indian sub-continent. Results are to be interpreted with respect to psychosocial contexts arising during the COVID-19 pandemic. Mental health programs can incorporate the variables of resilience and self-compassion in intervention among individuals with depression which have likely been beneficial in their process of recovery.

Contributing factors to heterogeneity in the timing of the onset of major depressive episode: Results from a national study

INTRODUCTION

It remains unclear whether specific clinical factors contribute to heterogeneity in the timing of the onset of major depression.

METHODS

Using a nationally representative US adult sample, the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions, we compared the characteristics of 5 different groups of patients defined by their age at onset: (i) before 18 years, (ii) between 18 and 34 years, (iii) between 35 and 44 years, (iv) between 45 and 59 years, and (v) 60 years or older. Specifically, we examined parental history of psychiatric disorders, history of childhood maltreatment experiences, sociodemographic characteristics, lifetime psychiatric disorders, and psychiatric disorders that occurred before the first major depressive episode (MDE).

RESULTS

Compared with first MDE occurring between 18 and 34 years, first MDE before 18 years was more strongly associated with childhood maltreatment and family history of psychiatric disorders, and less strongly linked to prior lifetime psychiatric disorders, whereas first MDE occurring at 60 years and older was more strongly associated with widowhood and a prior lifetime history of generalized anxiety disorder.

LIMITATIONS

Associations found cannot be interpzreted as causal relationships due to study design and the risk of recall bias.

CONCLUSION

Our results suggest substantial age differences in risk factors for first MDE. Improving early detection and treatment of major depression and other psychiatric disorders, and preventing childhood maltreatment may have broad benefits to reduce the burden of MDE at all ages.

Perceived Support and Sense of Social Belonging in Young Adults Who Have a Parent With a Mental Illness

This participatory action research explores the perceived social support of youth whose parents have a mental illness during their transition to adulthood. Social support is an important protection factor during this developmental period, but few studies have explored how these young adults perceive their social support. Nor has any study assessed whether participation in a group-based participatory action research project could improve these youth's sense of support. Purpose: (1) identify which aspects of social support these youth spontaneously address when talking about their experiences in Photovoice workshops; (2) explore how participants view these types of workshops as a good way to improve their sense of social support and belonging. Methodology: Ten young adults (nine women and one man) between the ages of 18 and 25 who have at least one parent with a mental illness participated in Photovoice meetings in 2019. These group meetings aimed to explore and share their experiences as young adults whose parents have a mental illness. The testimonies were combined with data obtained from the abbreviated version of the Social Provisions Scale and the Scale of Social Belonging. Results: The quantitative results suggest that participants consider their social support levels to be high, but their qualitative statements highlight low level or absence of parental support in terms of emotional, informative or instrumental levels. They see themselves as an important source of support for their parent and discuss the importance of having other supports figures (romantic partner, employer, friends, sibling, etc.). Conversely, they have difficulty asking for help for various reasons (including fear of stigma). They consider that their participation in this Photovoice project allowed them to feel heard, supported and to develop a sense of belonging to a group. Discussion: To conclude, clinical issues to be considered for psychosocial intervention with young adults of parents with a mental illness are discussed.

The role of parent-to-child maltreatment in the pathway of self-reported depressive symptoms in Pakistani adolescents

Background

Parent-to-child maltreatment has been demonstrated to drastically affect a child’s mental well-being and plays a significant role in developing depressive symptoms. However, little is established about the effect of frequency of parent-to-child maltreatment on the development of depressive symptoms among Pakistani adolescents.

Methods

A longitudinal prospective study was conducted, from 2015 to 2017, with 800 adolescents aged 11–17 years old recruited from 32 systematically selected urban and peri-urban areas of Karachi. First, these adolescents were screened for parent-to-child maltreatment in 2015 in a cross-sectional survey. Children with diagnosed psychiatric conditions were excluded from the study. In the second phase, these individuals were followed for 2 years to investigate the symptoms of depressive disorder using a validated tool, “CES-D (Center for Epidemiological Studies) Depression scale.” The Cox proportional algorithm was used to examine the relationship between the frequency of parent-to-child maltreatment and depressive symptoms.

Results

Approximately 11% of frequently, 9% of occasionally parent-to-child, and 7%of negligibly maltreated adolescents reported depressive symptoms over 2 years. The other significant predictors of depressive symptoms were no formal education of the child (RR: 3.15, 95% CI: 1.35–7.34), presence of stressful home environment (RR: 2.19, 95% CI: 1.22–3.94), and having both uneducated parents (RR: 1.70, 95% CI: 0.90–3.21). The frequently maltreated females were found to have 4 times the higher risk compared to rarely maltreated males. In addition, frequently maltreated males were twice likely to develop depressive symptoms.

Conclusion

The results suggested that frequent parent-to-child maltreatment occurring during childhood leads to the development of depressive symptoms later in the adolescence period. Thus, there is a dire need for interventions to raise awareness among the society on the issue of parent-to-child mistreatment to minimize later mental health consequences.

The Evolution in Anxiety and Depression with the Progression of the Pandemic in Adult Populations from Eight Countries and Four Continents

Nearly a year after the classification of the COVID-19 outbreak as a global pandemic, it is clear that different factors have contributed to an increase in psychological disorders, including public health measures that infringe on personal freedoms, growing financial losses, and conflicting messages. This study examined the evolution of psychosocial impacts with the progression of the pandemic in adult populations from different countries and continents, and identified, among a wide range of individual and country-level factors, which ones are contributing to this evolving psychological response. An online survey was conducted in May/June 2020 and in November 2020, among a sample of 17,833 adults (Phase 1: 8806; Phase 2: 9027) from eight countries/regions (Canada, the United States, England, Switzerland, Belgium, Hong Kong, the Philippines, New Zealand). Probable generalized anxiety disorder (GAD) and major depressive episode (MDE) were assessed. The independent role of potential factors was examined using multilevel logistic regression. Probable GAD or MDE was indicated by 30.1% and 32.5% of the respondents during phases 1 and 2, respectively (a 7.9% increase over time), with an important variation according to countries/regions (range from 22.3% in Switzerland to 38.8% in the Philippines). This proportion exceeded 50% among young adults (18-24 years old) in all countries except for Switzerland. Beyond young age, several factors negatively influenced mental health in times of pandemic; important factors were found, including weak sense of coherence (adjusted odds ratio aOR = 3.89), false beliefs (aOR = 2.33), and self-isolation/quarantine (aOR = 2.01). The world has entered a new era dominated by psychological suffering and rising demand for mental health interventions, along a continuum from health promotion to specialized healthcare. More than ever, we need to innovate and build interventions aimed at strengthening key protective factors, such as sense of coherence, in the fight against the adversity caused by the concurrent pandemic and infodemic.

Risk and resource factors for depressive symptoms during adolescence and emerging adulthood - A 5-year follow-up using population-based data of the BELLA study

INTRODUCTION

Depression is one of the most common mental disorders in adolescents and young adults worldwide, and causes a high burden for both individuals and society. The present study aims to investigate the role of risk and resource factors for depressive symptoms during adolescence and emerging adulthood in a German population-based cohort.

METHODS

Within the longitudinal BELLA study, data on risk and resource factors were collected among n = 632 children and adolescents aged 11 to 17 years. Depressive symptoms were measured five years later. Multivariate linear regression models served to investigate effects of risk and resource factors on depressive symptoms. Regression models were stratified by gender. Moreover, we explored potential interaction effects.

RESULTS

A negative mother-child relationship predicted depressive symptoms in girls, whereas school stress served as a risk factor in boys. Peer competence was associated with fewer depressive symptoms in girls, and family cohesion was identified as a resource factor in boys. In addition, few moderating effects of resource factors on the association between risk factors and depressive symptoms were found.

LIMITATIONS

As the BELLA study is a population-based observational study, we only identified associations between risk and resource factors and no cause-effect relationships.

CONCLUSIONS

Findings provide evidence of gender-specific risk and resource factors for depression. Individuals who are exposed to risk factors must be monitored during the transition into adulthood. Gender-sensitive prevention and early intervention programs are needed.

Association of Social Support During Adolescence With Depression, Anxiety, and Suicidal Ideation in Young Adults

Importance

Mental health problems are common during the transition from adolescence to young adulthood. Although perceived social support and mental health problems have been shown to be concurrently associated, longitudinal studies are lacking to document the directionality of this association, especially in emerging adulthood (late teens to late 20s).

Objective

To test whether social support in emerging adulthood protects against later depression, anxiety, and suicidal ideation and suicide attempts after adjusting for a range of confounders, including prior mental health problems and family characteristics.

Design, Setting, and Participants

This population-based cohort study included 1174 participants from the Quebec Longitudinal Study of Child Development. Participants underwent yearly or biennial assessment (starting from age 5 months to age 20 years). Data were collected from March 16, 1998, through June 1, 2018.

Main Outcomes and Measures

Self-reported perceived social support was measured at age 19 years using the 10-item Social Provision Scale. Mental health problems, including depressive and anxiety symptoms as well as suicidal ideation and attempts, were measured at age 20 years. Social support and mental health problem raw scores were converted to z-scores to ease interpretation. Depressive and anxiety symptoms were categorized using validated cutoffs to determine clinical significance.

Results

The study consisted of 1174 participants (574 female [48.89%] and 600 male [51.11%] individuals). Emerging adults with higher levels of perceived social support at age 19 years reported fewer mental health problems 1 year later, even after adjusting for a range of mental health problems in adolescence at ages 15 and 17 years (eg, depressive and anxiety symptoms and suicidal ideation and attempts) and family characteristics (eg, socioeconomic status and family functioning and structure). Higher perceived social support was associated with fewer symptoms of depression (β = -0.23; 95% CI, -0.26 to -0.18; P = <.001 and odds ratio [OR], 0.53; 95% CI, 0.42-0.66 for severe depression) and anxiety (β = -0.10; 95% CI, -0.15 to -0.04; P < .001 and OR, 0.78; 95% CI, 0.62-0.98 for severe anxiety). Higher perceived social support was associated with a lower risk for suicide-related outcomes (OR, 0.59 [95% CI, 0.50-0.70] for suicidal ideation and OR, 0.60 [95% CI, 0.46-0.79] for suicide attempts).

Conclusions and Relevance

In this cohort study, emerging adults who perceived higher levels of social support reported experiencing fewer mental health problems 1 year later. These findings suggest that perceived social support may protect against mental health problems during the transition into adulthood, even in those who experience mental health problems in adolescence. Leveraging social support in prevention and treatment options may protect against mental health symptoms during this transition period.

Physical activity of people with mental disorders compared to the general population: a systematic review of longitudinal cohort studies

PURPOSE

We investigated if (a) people with lower physical activity have an increased risk of subsequent mental disorders (compared to those with higher physical activity); and (b) people with mental disorders have reduced subsequent physical activity (compared to those without mental disorders).

METHODS

A systematic review of population-based longitudinal studies examining physical activity and mental disorders was conducted. Mental disorders were defined by International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders. The results were described in a narrative summary.

RESULTS

Twenty-two studies were included. The majority (19) examined mood disorders and physical activity. Only two studies found consistent association between lower physical activity and a reduced risk of subsequent mental disorders. One study found the bidirectional association between physical activity and major depression. Twelve studies found mixed results (i.e., no consistency in direction and significance of the findings), and seven studies found no association between the variables of interest.

CONCLUSIONS

There is a lack of consistent evidence linking physical activity to be either a risk factor or consequence of mental disorders.

Intergenerational Educational Pathways and Self-Rated Health in Adolescence and Young Adulthood: Results of the German KiGGS Cohort

Health differences in social mobility are often analysed by income differences or different occupational positions. However, in early adulthood many young people still have very diffuse income situations and are not always fully integrated into the labour market despite many having finished school. This article focusses on the link between intergenerational educational pathways and self-rated health (SRH) among young adults considering their SRH in adolescence. The data source used is the German KiGGS cohort study. The analysis sample comprises 2175 young people at baseline (t0: 2003⁻2006 age 14⁻17) and first follow-up (t1: 2009⁻2012 age 19⁻24). Combining parent's and young people's highest school degree, the data can trace patterns of intergenerational educational pathways (constant high level of education, upward mobility, downward mobility, constant low level of education). Young people's SRH was recorded at t0 and t1. During adolescence and young adulthood, participants were less likely to report poor SRH if they had a constant high intergenerational education or if they were upwardly mobile. The differences were particularly striking among young adults: average marginal effects (AME) for poor SRH showed much higher risk among downwardly mobile compared to peers with an intergenerational constant high education (AME: 0.175 [0.099; 0.251]), while the upwardly mobile had a significantly lower risk for less than good SRH than peers with an intergenerational constant low level of education (AME: -0.058 [-0.113; -0.004]). In the context of great societal demands and personal developmental needs, educational differences in health tend to increase in young adulthood. Public Health should pay more attention to educational and health inequalities in young adulthood.

Mild and severe childhood depression: differences and implications for prevention programs in the school setting

PURPOSE

The study had two goals as follows: 1) to identify the prevalence of children with mild and severe depression (MD and SD), exploring sex differences; and 2) to determine possible significant differences in adaptive and clinical variables between children with different levels of depression (absence of depression, MD, and SD).

MATERIALS AND METHODS

We used a sample of 420 participants aged 7-10 years (53.3% boys) enrolled in third and fourth grade of primary education, from schools in the Basque Country (Spain). The Children's Depression Scale (CDS, self-assessment) was administered as well as six more assessment instruments.

RESULTS

It was found that 84.2% of children had no depression, 10% had MD, and 5.8% had SD. Compared with children with depressive symptoms, participants without depression had significantly: 1) lower levels of maladjustment, stress, emotional symptoms, internalizing problems, and behavioral problems; and 2) higher levels of personal adjustment, resilience, social skills, and self-concept. In addition, children with MD had significantly lower levels of clinical maladjustment, emotional symptoms, and stress than children with SD. However, no differences were found in school maladjustment, internalizing problems, behavioral problems, personal adjustment, resilience, social skills, and self-concept between children with MD and SD.

CONCLUSION

The discussion emphasizes the importance of identifying children with MD and implementing universal prevention programs from an early age.

A brief early intervention for adolescent depression that targets emotional mental images and memories: protocol for a feasibility randomised controlled trial (IMAGINE trial)

BACKGROUND

Adolescent depression is common and impairing. There is an urgent need to develop early interventions to prevent depression becoming entrenched. However, current psychological interventions are difficult to access and show limited evidence of effectiveness. Schools offer a promising setting to enhance access to interventions, including reducing common barriers such as time away from education. Distressing negative mental images and a deficit in positive future images, alongside overgeneral autobiographical memories, have been implicated in depression across the lifespan, and interventions targeting them in adults have shown promise. Here, we combine techniques targeting these cognitive processes into a novel, brief psychological intervention for adolescent depression. This feasibility randomised controlled trial will test the feasibility and acceptability of delivering this imagery-based cognitive behavioural intervention in schools.

METHODS/DESIGN

Fifty-six adolescents (aged 16-18) with high symptoms of depression will be recruited from schools. Participants will be randomly allocated to the imagery-based cognitive behavioural intervention (ICBI) or the control intervention, non-directive supportive therapy (NDST). Data on feasibility and acceptability will be recorded throughout, including data on recruitment, retention and adherence rates as well as adverse events. In addition, symptom assessment will take place pre-intervention, post-intervention and at 3-month follow-up. Primarily, the trial aims to establish whether it is feasible and acceptable to carry out this project in a school setting. Secondary objectives include collecting data on clinical measures, including depression and anxiety, and measures of the mechanisms proposed to be targeted by the intervention. The acceptability of using technology in assessment and treatment will also be evaluated.

DISCUSSION

Feasibility, acceptability and symptom data for this brief intervention will inform whether an efficacy randomised controlled trial is warranted and aid planning of this trial. If this intervention is shown in a subsequent definitive trial to be safe, clinically effective and cost-effective, it has potential to be rolled out as an intervention and so would significantly extend the range of therapies available for adolescent depression. This psychological intervention draws on cognitive mechanism research suggesting a powerful relationship between emotion and memory and uses imagery as a cognitive target in an attempt to improve interventions for adolescent depression.

Co-development of Problem Gambling and Depression Symptoms in Emerging Adults: A Parallel-Process Latent Class Growth Model

This study examines whether there are multiple joint trajectories of depression and problem gambling co-development in a sample of emerging adults. Data were from the Manitoba Longitudinal Study of Young Adults (n = 679), which was collected in 4 waves across 5 years (age 18-20 at baseline). Parallel process latent class growth modeling was used to identified 5 joint trajectory classes: low decreasing gambling, low increasing depression (81%); low stable gambling, moderate decreasing depression (9%); low stable gambling, high decreasing depression (5%); low stable gambling, moderate stable depression (3%); moderate stable problem gambling, no depression (2%). There was no evidence of reciprocal growth in problem gambling and depression in any of the joint classes. Multinomial logistic regression analyses of baseline risk and protective factors found that only neuroticism, escape-avoidance coping, and perceived level of family social support were significant predictors of joint trajectory class membership. Consistent with the pathways model framework, we observed that individuals in the problem gambling only class were more likely using gambling as a stable way to cope with negative emotions. Similarly, high levels of neuroticism and low levels of family support were associated with increased odds of being in a class with moderate to high levels of depressive symptoms (but low gambling problems). The results suggest that interventions for problem gambling and/or depression need to focus on promoting more adaptive coping skills among more "at-risk" young adults, and such interventions should be tailored in relation to specific subtypes of comorbid mental illness.

Association between physical activity patterns and anthropometric characteristics of adults: an issue of public health?

Study aim: The aim of this study was to evaluate the association between objectively measured daily physical activity (PA) and body fat mass (BF) and body mass index (BMI). A further aim was to analyse the variance of PA between quartiles of BF and BMI.

Material and methods: A cross-sectional, observational study of 126 university students (53 males aged 20.46 ± 2.04 years and 73 female aged 19.69 ± 1.32 years) was conducted.

Results: The female participants and PA characteristics explain 57.10% of BF variance and the model was statistically signifi­cant (F(6, 875) = 196.38; p = 0.001). BMI was also included in the model. Standard binary logistic regression was used to test the hypothesis that female sex and PA characteristics can influence overweight. The full model containing all variables was statistically significant (G2(6) = 58.598, p-value = 0.001). Analysis of variance between BF quartiles revealed statistically sig­nificant differences in male participants in light PA (p = 0.001; ES = 0.09), moderate PA (p = 0.001; ES = 0.042) and vigorous PA (p = 0.001; ES = 0.130).

Conclusions: The statistical model in the regression analysis suggests that low and vigorous levels of PA explain 57% of BF variance in female participants.

Children's Physical Activity and Depression: A Meta-analysis

CONTEXT

Research regarding the protective effects of early physical activity on depression has yielded conflicting results.

OBJECTIVE

Our objective was to synthesize observational studies examining the association of physical activity in childhood and adolescence with depression.

DATA SOURCES

Studies (from 2005 to 2015) were identified by using a comprehensive search strategy.

STUDY SELECTION

The included studies measured physical activity in childhood or adolescence and examined its association with depression.

DATA EXTRACTION

Data were extracted by 2 independent coders. Estimates were examined by using random-effects meta-analysis.

RESULTS

Fifty independent samples (89 894 participants) were included, and the mean effect size was significant (r = -0.14; 95% confidence interval [CI] = -0.19 to -0.10). Moderator analyses revealed stronger effect sizes in studies with cross-sectional versus longitudinal designs (k = 36, r = -0.17; 95% CI = -0.23 to -0.10 vs k = 14, r = -0.07; 95% CI = -0.10 to -0.04); using depression self-report versus interview (k = 46, r = -0.15; 95% CI = -0.20 to -0.10 vs k = 4, r = -0.05; 95% CI = -0.09 to -0.01); using validated versus nonvalidated physical activity measures (k = 29, r = -0.18; 95% CI = -0.26 to -0.09 vs k = 21, r = -0.08; 95% CI = -0.11 to -0.05); and using measures of frequency and intensity of physical activity versus intensity alone (k = 27, r = -0.17; 95% CI = -0.25 to -0.09 vs k = 7, r = -0.05; 95% CI = -0.09 to -0.01).

LIMITATIONS

Limitations included a lack of standardized measures of physical activity; use of self-report of depression in majority of studies; and a small number of longitudinal studies.

CONCLUSIONS

Physical activity is associated with decreased concurrent depressive symptoms; the association with future depressive symptoms is weak.

Childhood Depression: Relation to Adaptive, Clinical and Predictor Variables

The study had two goals: (1) to explore the relations between self-assessed childhood depression and other adaptive and clinical variables (2) to identify predictor variables of childhood depression. Participants were 420 students aged 7-10 years old (53.3% boys, 46.7% girls). Results revealed: (1) positive correlations between depression and clinical maladjustment, school maladjustment, emotional symptoms, internalizing and externalizing problems, problem behaviors, emotional reactivity, and childhood stress; and (2) negative correlations between depression and personal adaptation, global self-concept, social skills, and resilience (sense of competence and affiliation). Linear regression analysis including the global dimensions revealed 4 predictors of childhood depression that explained 50.6% of the variance: high clinical maladjustment, low global self-concept, high level of stress, and poor social skills. However, upon introducing the sub-dimensions, 9 predictor variables emerged that explained 56.4% of the variance: many internalizing problems, low family self-concept, high anxiety, low responsibility, low personal self-assessment, high social stress, few aggressive behaviors toward peers, many health/psychosomatic problems, and external locus of control. The discussion addresses the importance of implementing prevention programs for childhood depression at early ages.

Factors Associated with Suicidal Thought and Help-Seeking Behaviour in Transition-Aged Youth versus Adults

OBJECTIVE

Suicide is a leading cause of death for transition-aged youth (TAY), and yet few studies examine correlates of suicidal ideation specifically in this age demographic (age 18-24 years). The transition to adulthood is a unique context, marked by novel stressors (e.g., joining the workforce) and increased independence, which may influence risk factors for suicidal ideation. This study examined correlates of suicidal ideation in TAY and adults and contrasted profiles across age.

METHODS

We used 4 biannual cycles (2005, 2007, 2009, 2011) of the Canadian Community Health Survey, a population-based cross-sectional survey on health. We used logistic regression to assess the association between suicidal ideation and depression, distress, alcohol use, smoking, exercise, sedentary behaviour, chronic illness, restrictions to daily living, perceived physical and mental health, and perceived social support independently in both TAY ( n = 4427) and adults ( n = 14,452). We subsequently assessed possible interactions with age (18-24 v. 25-44 years) and sex and differences in help-seeking behaviour in a combined model.

RESULT

TAY exhibited higher rates of suicidal ideation than adults did ( P < 0.001). Numerous factors were associated with suicidal ideation in TAY. Notably, alcohol abstinence was associated with decreased suicidal ideation in TAY but not for adults. Moreover, when depressed, TAY were significantly less likely to have received professional mental health help than adults (odds ratio = 0.64, 95% CI, 0.43 to 0.94).

CONCLUSIONS

Suicidal ideation is more prevalent in TAY than adults, and its consequences may be aggravated by poor treatment-seeking behaviour in at-risk (i.e. depressed) individuals. These different risk profiles substantiate the recent shift toward clinical interventions focusing on transition-aged youth, rather than traditional child (<18 years) and adult (>18 years) services.

Social support and protection from depression: systematic review of current findings in Western countries

BACKGROUND

Numerous studies report an association between social support and protection from depression, but no systematic review or meta-analysis exists on this topic.

AIMS

To review systematically the characteristics of social support (types and source) associated with protection from depression across life periods (childhood and adolescence; adulthood; older age) and by study design (cross-sectional v cohort studies).

METHOD

A systematic literature search conducted in February 2015 yielded 100 eligible studies. Study quality was assessed using a critical appraisal checklist, followed by meta-analyses.

RESULTS

Sources of support varied across life periods, with parental support being most important among children and adolescents, whereas adults and older adults relied more on spouses, followed by family and then friends. Significant heterogeneity in social support measurement was noted. Effects were weaker in both magnitude and significance in cohort studies.

CONCLUSIONS

Knowledge gaps remain due to social support measurement heterogeneity and to evidence of reverse causality bias.

Association of child maltreatment and depressive symptoms among Puerto Rican youth

This article compares multiple types of child maltreatment among Puerto Rican youth. We seek to expand the limited knowledge of the effects of multiple types of maltreatment on depressive symptoms in a specific Latino population as emerging studies indicate that children who are exposed to one type of maltreatment are often exposed to other types. This study examines the predictive strength of different and multiple types of lifetime child maltreatment (i.e., physical, sexual, and emotional abuse; and neglect), and the effect of youth support from parents, youth coping, youth self-esteem, and place of residence on depressive symptoms among Puerto Rican youth. Secondary data analyses were performed using three annual waves (2000-2004) of data from the Boricua Youth Study. The analytic sample consists of 1041 10-13 year old Puerto Rican youth living in New York and Puerto Rico. Results indicate that: (1) youth who experienced 'sexual abuse only', 'multiple maltreatment' (2 or more types of maltreatment), 'physical abuse only' have a significant increase in depressive symptoms (75.1%, 61.6%, and 40.5% respectively) compared to those without maltreatment; and (2) place of residence, exposure to violence, and mental disorders were significant risk factors. When developing psychosocial interventions, professionals should particularly focus on youth who report past lifetime experience with child maltreatment. Particular attention should be given to children living in the Bronx, New York and similar urban low-income areas who report past lifetime experience with multiple types of child maltreatment and who present symptoms or a diagnosis of co-occurring mental health problems.

Psychosocial Pathways Linking Adverse Childhood Experiences to Mental Health in Recently Deployed Canadian Military Service Members

Multiple pathways have been suggested to account for the relationship of adverse childhood experiences (ACEs) and well-being in adulthood, including interpersonal difficulties, the underestimation of one's sense of mastery, and a greater propensity to experience stressors later in life. This study was conducted to examine the association between ACEs and mental health in Canadian Armed Forces (CAF) personnel, and the possible mediating roles of social support, mastery, and combat stressors in that relationship. The study consisted of a prospective analysis involving 3,319 CAF members upon their return from an overseas deployment. Results were that ACEs were associated with poorer mental health (β = -.14, p < .001) and that approximately 42.6% of this relationship could be explained by the mediating effects of low social support, low mastery, and a greater number of combat stressors. The full model, including the covariates, ACEs, social support, mastery, and combat stressors as correlates of postdeployment mental health, was statistically significant with adjusted R(2) = .28, F(9, 3309) = 141.96, p < .001. On the whole, results suggested that social support, mastery, and life stressors may be possible targets for interventions to minimize the impact of ACEs on later mental health in military personnel.

Childhood household dysfunction, school performance and psychiatric care utilisation in young adults: a register study of 96 399 individuals in Stockholm County

BACKGROUND

Exposure to childhood household dysfunction increases the risk of psychiatric morbidity. Although school performance also has been linked with psychiatric morbidity, limited research has considered school performance as a mediating factor. To address this gap in the literature, the current register study examined whether school performance mediates the association between childhood household dysfunction (experienced between birth and age 14 years) and psychiatric care utilisation in young adulthood.

METHODS

We used a Swedish cohort of 96 399 individuals born during 1987-1991. Indicators of childhood household dysfunction were familial death, parental substance abuse and psychiatric morbidity, parental somatic disease, parental criminality, parental separation/single-parent household, public assistance recipiency and residential instability. Final school grades from the 9th year of compulsory school were used to create five categories. Estimates of risk of psychiatric care utilisation (measured as inpatient, outpatient and primary care) after the age of 18 years were calculated as HRs with 95% CIs. Mediation was tested with the bootstrap approach.

RESULTS

Cumulative exposure to childhood household dysfunction was positively associated with psychiatric care utilisation. Specifically, individuals exposed to three or more indicators with incomplete school grades had the highest risk (HR=3.7 (95% CI 3.3 to 4.1) after adjusting for demographics), compared to individuals exposed to no indicators with highest grades. School performance was found to mediate the relationship.

CONCLUSIONS

Our findings suggest that future efforts to prevent or mitigate the negative effects of childhood household dysfunction on psychiatric morbidity may benefit from integration of strategies that improve school performance among vulnerable youth.

Socioeconomic Status Across the Life Course and Cognitive Function Among Older Adults: An Examination of the Latency, Pathways, and Accumulation Hypotheses

OBJECTIVE

This study investigated the relationship between life course socioeconomic status (SES) and cognitive function among older adults in the United States over a 12-year observation period. The mediation of adult SES on the association between childhood SES and cognition was examined, along with the relationship between cumulative SES and cognition.

METHOD

Using a nationally representative sample from the Health and Retirement Study, cognitive status and change in cognition from 1998 to 2010 were examined using growth curve models.

RESULTS

The results showed that cognitive function varied within-persons and between-persons. SES disadvantage in childhood was associated with lower cognitive function at baseline. Adult SES mediated the relationship between childhood SES and cognitive function. Persons with higher cumulative SES demonstrated an advantage in cognitive function.

DISCUSSION

Childhood SES and adult SES both had relationships with cognitive status and, to a lesser degree, change in cognition in later life.

Nonpharmacologic treatments for depression related to reproductive events

There is a growing body of evidence suggesting that nonpharmacological interventions have an appropriate place in the treatment of major depressive disorders (MDDs) as both stand-alone and supplemental treatments. Because women may be reluctant to use psychotropic medications due to strong values or treatment preferences during specific reproductive events, clinicians need to be able to offer empirically based alternatives to medication. In this review, we present recent findings from studies of acupuncture, bright light therapy, electroconvulsive therapy, omega fatty acid supplementation, physical activity, and psychosocial intervention for women experiencing depressive symptoms in the contexts of menstruation, pregnancy, postpartum, and menopause.
