The association between digital communication tool use and perceived mental health among older adults in Canada
This study examines the association between digital communication tool use and perceived mental health among older adults aged 55 years and older in Canada, using data from the 2022 Canadian Internet Use Survey. The sample included 13,536 adults, weighted to represent 12,735,479 individuals. Perceived mental health was self-rated and assessed using a 5-point Likert scale. Digital communication tool usage was measured by reported engagement in act…
Sex‐specific pathways from early irritability trajectories to later suicidal ideations and behaviors
BACKGROUND: Previous studies have demonstrated that children with high irritability are at increased risk for suicidal ideations and behaviors. However, they have mostly relied on teacher reports and shown mixed findings regarding sex differences. We aimed to identify developmental trajectories of childhood irritability, test their direct and indirect (through psychopathology) associations with adolescent suicidal ideations and behaviors, and exa…
Epidemiology of violence and suicide risk in Senegal
Assessing violence and suicide risk at the population level is essential to inform public health policies and guide prevention efforts for mental health. In Senegal, as in much of sub-Saharan Africa, such data remain scarce. This study aims to fill that gap by estimating the prevalence of violence and suicide risk, and identifying associated factors in the Senegalese population. This nationwide, observational, cross-sectional, population-based an…
Trends and risk factors for suicide mortality in India from 2001–2019
One in four of all global suicide deaths occurs in India, yet the epidemiology of suicide mortality in India remains largely undocumented. We analyzed over 20,000 suicides among 829,000 deaths collected from 2001-2019 within a nationally representative random sample of about 1% of Indian homes using lay field reporting with dual central medical adjudication of causes. We applied suicide death proportions to national demographic totals to estimate…
Bidirectional Associations Between Civic Engagement, Depressive Symptoms, and Suicidality in Youth
INTRODUCTION: Civic engagement is common in youth, yet its longitudinal association with mental health remains understudied. This study aims to document bidirectional associations between civic engagement, depressive symptoms, and suicidality at 20 and 23. METHODS: We included 1451 participants born in 1997/98 from the Québec Longitudinal Study of Child Development in Canada. At 20 and 23, youth self-reported their engagement in five types of civ…
A longitudinal study of adolescent pathways differentiating suicide ideation and attempt in early adulthood
OBJECTIVE: Suicide ideation and attempt are leading risk factors for mortality in young adults. However, the adolescent risk factors distinguishing suicide ideation from attempt in young adults remain unclear. The present study aimed to examine the extent to which within-person stability and change in depressive symptoms, school difficulties, and peer victimization from ages 12 to 17 were differentially associated with later suicide ideation and …
The interplay of maternal and paternal postpartum depressive symptoms with children's internalizing and externalizing symptoms from childhood to adolescence
BACKGROUND: Maternal postpartum depression is an important risk factor for internalizing and externalizing problems in children. The role of concurrent paternal depression remains unclear, especially by socioeconomic status. This study examined independent and interactive associations of postpartum maternal and paternal depression with children's internalizing/externalizing symptoms throughout childhood and adolescence (ages 3.5-17 years). METHOD…
Socio-medical factors associated with neurodevelopmental disorders on the Kenyan coast
Neurodevelopmental disorders (NDDs) are a group of conditions with their onset during the early developmental period and include conditions such as autism and intellectual disability. Occurrence of NDDs is thought to be determined by both genetic and environmental factors, but data on the role of environmental factors for NDD in Africa is limited. This study investigates environmental influences on NDDs in children from Kenya. This case-control s…
Does early child negative emotionality moderate the association between maternal stimulation and academic readiness and achievement
We investigated whether child temperament (negative emotionality, 5 months) moderated the association between maternal stimulation (5 months–21⁄2 years) and academic readiness and achievement (vocabulary, mathematics, and reading). We applied structural equation modeling to the data from the Quebec Longitudinal Study of Child Development (N = 1121–1448; mostly Whites; 47% girls). Compared to children with low negative emotionality, those with hig…
Sex differences in alcohol use patterns and related harms
In northern Tanzania, alcohol use disorders (AUD) are under-diagnosed and under-treated, and current services are mostly limited to men in clinical settings despite significant alcohol-related harm in the community. The study objective was to identify sex differences in alcohol use and alcohol-related harms within and across community and clinical settings. This was a congruent triangulation mixed methods study consisting of focus group discussio…
Prevalence and patterns of substance use in West Africa
Introduction Substance use is a growing public health concern in West Africa, contributing to significant morbidity, mortality, and socioeconomic challenges. Despite the increasing prevalence, comprehensive data on the patterns and factors influencing substance use in the region remain limited. This systematic review and meta-analysis aim to synthesize existing research on the prevalence and patterns of substance use in West Africa, providing cri…
Personal, Family, and Environmental Factors Associated with Somatic Complaints in School-Aged Child Victims of Sexual Abuse
Attachment Styles and Suicidal Thoughts and Behaviors
Introduction: This meta-analysis examined the association between dimensional and categorical conceptualizations of attachment styles and suicidal thoughts and behaviors (STBs). Methods: Random-effects meta-analysis was conducted to examine the associations between categorical secure attachment, categorical insecure attachment, and insecure attachment dimensions and STBs. Methodological moderators were also explored. This protocol was registered …
Psychometric properties of the Social Behavior Questionnaire (SBQ) in a longitudinal population-based sample
We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5–12 years. Children ( n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child Development. Mothers reported the frequency with which children presented social and emotional behaviors from …
The Long-Term Health and Human Capital Consequences of Adverse Childhood Experiences in the Birth to Thirty Cohort
Human capital-that is the cumulative abilities, education, social skills, and mental and physical health one possesses-is increasingly recognized as key to the reduction of inequality in societies. Adverse childhood experiences have been linked to a range of human capital indicators, with the majority of research in high-income, western settings. This study aims to examine the link between adverse childhood experiences and adult human capital in …
Parental affective personality and children's self‐reported internalising and externalising behaviour
Past research has demonstrated associations between parental personality traits and children's behaviour. However, fathers have been largely excluded from this research, and mothers often rate both their own personality and their child's behaviour, contributing to shared method variance. This study contributes to the literature by examining associations between parental biologically based affective personality traits, analysed separately for moth…
Pathways of association between disordered eating in adolescence and mental health outcomes in young adulthood during the Covid-19 pandemic
Identifying environmental pathways between irritability during childhood and suicidal ideation and attempt in adolescence
BACKGROUND: Irritable children are at increased risk of suicidal ideation and suicide attempt, but the underlying environmental mechanisms accounting for these associations are largely unknown. We aimed to investigate the mediating role of peer victimization and harsh parenting in the association between childhood irritability and adolescent suicidal ideation and attempt. METHOD: N = 1,483 participants from the Québec Longitudinal Study of Child …
Developmental profiles of childhood attention‐deficit/hyperactivity disorder and irritability
BACKGROUND: Irritability is frequently comorbid with ADHD. Although irritability alone has been linked to deleterious mental health and adaptive issues, the joint developmental course of ADHD and irritability symptoms during childhood as well as its association with later mental health and suicidal outcomes is not fully understood. We aimed to describe the developmental trajectories of childhood ADHD and irritability symptoms and to quantify thei…
My Life during the Lockdown”

We used a self-reported online questionnaire (answers on a 5-point scale or binary), composed of 73 questions investigating the opinions, feelings, and emotions of teenagers, along with sociodemographic information and measures of the exp…
Childhood out-of-home placement and pathways to adult socioeconomic outcomes
Cybervictimization in adolescence and its association with subsequent suicidal ideation/attempt beyond face‐to‐face victimization
BACKGROUND: Cross-sectional associations have been documented between cybervictimization and suicidal risk; however, prospective associations remain unclear. METHODS: Participants were members of the Quebec Longitudinal Study of Child Development (QLSCD), a prospective birth cohort of 2,120 individuals followed from birth (1997/98) to age 17 years (2014/15). Cybervictimization and face-to-face victimization experienced since the beginning of the …
Adaptive Behavior of Sheltered Homeless Children in the French Enfams Survey
Objectives. To describe the adaptive behaviors in a large sample of homeless children and identify factors associated with developmental delay. Methods. Data were from a cross-sectional survey of 557 children younger than 6 years randomly sampled among homeless sheltered families in the Paris region, France (January–May 2013). An interviewer and a psychologist conducted face-to-face interviews to collect information on sociodemographic and health…
Metasynthesis
Metasyntheses offer an appropriate balance between an objective framework, a rigorously scientific approach to data analysis and the necessary contribution of the researcher's subjectivity in the construction of the final work. They propose a third level of comprehension and interpretation that brings original insights, improve the global understanding in psychiatry, and propose immediate therapeutic implications. They should be included in the p…
