The current prospective longitudinal study evaluated brooding rumination as an intervening mechanism of the association between COVID-19-related stress and internalizing symptoms during the first year of the pandemic. Attention-deficit/hyperactivity disorder (ADHD) status and adolescent sex were tested as moderators of the indirect effect.…

Youth purpose was investigated using a two-phase embedded design with youth participating in Scouts BSA (N = 3,943), ages 9-20 (M = 14.0, SD = 1.9). Participating Scouts were mostly White (91%) and male (98%). In Phase 1, we conducted a two-step cluster analysis on Scouts' survey responses to three purpose dimensions (personal meaning,…

Background: Developmental assets foster positive health outcomes among adolescents, but have not been studied in adolescents with chronic illness or depression, two conditions that impact behaviors in school. We examined parent-reported assets in a national sample of adolescents and compared the number and types of assets by health statuses.…

Societal belongingness -- feelings of being a connected, an affiliated, and a respected member of the larger society -- may contribute to the understanding of adolescent development both as a person and a member of society in a multicultural context. The current study examined the psychometric properties and measurement invariance of the…

The current longitudinal study examined the predictive associations between the development of future perceptions in adolescence and depressive symptoms in adolescence and early and middle adulthood. Participants (N = 1,527; 48.3% female; broadly representative of Western Germany with respect to race/ethnicity and socioeconomic status) were…

Background: Research has established a bidirectional association between sleep disturbances and depression in both adults and youth, as well as links between depression and circadian rhythms and chronotype, predominantly in adult populations. However, the link between chronotype and depression in the general adolescent population, independently of…

Acne is a hallmark of adolescence, affecting 85% of youth between the ages of 12 and 25 worldwide. Perhaps because of its ubiquity and minimal impact on physical functioning, acne is often dismissed as a time-delimited cosmetic nuisance and has been summarily neglected by developmental scientists. However, emerging evidence suggests that acne is…

Adolescence is a critical phase in which physical, psychological, and intellectual challenges occur. This study assesses the prevalence and correlates of depression and anxiety among a national sample of adolescents. A cross-sectional correlational design using depression, anxiety, and stress scale was used. Our data revealed that 49.1% and 78.2%…

Experiences of dating violence are widespread among adolescents. Therefore, increasing the understanding on the developmental antecedents is crucial. However, most existing studies involve cross-sectional designs, which poses a challenge in better understanding the developmental precursors of dating violence victimization. To address this, we…

The mental health and well-being of children and adolescents are critical public health concerns globally.

Less is known about mental health in adults with a history of language problems. This paper presents a systematic review and meta-analysis that addresses this gap in the literature. Specifically, it summarises the…

Seventeen-year-olds (N = 32,325) from the National Surveys on Drug Use and Health (NSDUH) for 2008 to 2019 were included. The proportion of 17-year-olds reporting depression during their…

A diagnosis of gender dysphoria remains the primary requirement for transgender people to receive medical and legal gender affirmation services. Three focus groups conducted in 2018 with transgender and gender diverse (TGD) adolescents were assessed to understand how they define and use the term dysphoria and how the clinical discourse of gender…

One particular developmental task during adolescence is to regulate fluctuating moods to successfully transition through this period. The aim of this person-centered study was to identify distinct developmental trajectories of adolescent mood variability and to compare adolescents in different trajectories on changes in depressive symptoms,…
