Introduction: Sustained participation in physical education classes during adolescence can help promote lifelong engagement in physical activity, which is vital for the physical and mental health of adolescents. Self-concept, particularly in the domains of global and physical appearance self-perceptions, has been identified as a key predictor of…

Introduction: Recent evidence demonstrates an association between social media addiction (SMA) and aggressive behaviors; however, the longitudinal relationship between these two variables remains not fully understood. The aim of this study was to examine the longitudinal relationship between SMA and aggressive behaviors (overt and relational…

This study examines adolescents' coping styles, with relation to their gender and age and level, of six types of problems. The participants were 1843 adolescents (51.7% female and 48.3% male) from the Sultanate of Oman with a mean age of 15.75. Two scales examining general adaptive and maladaptive coping styles and levels of school, economic,…

The most common dating goals of adolescents are identity, intimacy, status and sex. In this study of Australian youth (16-30 years, N = 208), dating goals were expected to explain goal-consistent behavior in each domain. Also, goals coupled with consistent behavior were expected to be associated with greater satisfaction in each domain. Age,…

Research has shown a positive relationship between substance use and delinquent-type behaviours among adolescents. The aim of this study is to explore the temporal relationships between these outcomes through secondary data analysis of a longitudinal study of high-school students' risk behaviours. Two regression models were compared and gender,…

Identity formation is an essential developmental challenge associated with adolescence ([17], [20] and [21]). Berzonsky (1988) developed a social-cognitive model that distinguishes three styles by which adolescents engage the tasks associated with identity formation: informational, normative, and diffuse-avoidant. Focusing on studies (K = 62) that…

Several risk factors, including female sex, racial minority status, and family poverty, have been implicated in adolescents' depression. The present study focused on the role of one specific aspect of adolescents' ecological context, interactions with adults, in depressive symptomology. We examined the relationship between perceived support from…

The present paper investigates possible gender and age differences on emotional states (state depression and state anxiety) and sense of coherence (SOC) as well as the association between SOC and emotional states. The cross-sectional sectional sample consists of 1209 adolescents 13-18 years from public elementary and secondary schools in…

This study examines the relationship between dating violence, forced sexual intercourse (FSI), and four measures of sexual risk taking (i.e., age at first sex, number of recent (within the last three months) sex partners, alcohol/drug use at last sex, and condom use at last sex) among a sample of 1124 ethnically diverse sexually active adolescents…

Despite the fact that psychosocial and functional impairment has long been acknowledged as an important aspect of psychiatric diagnosis and treatment, relatively little is known about the longitudinal relationship between psychiatric symptoms and functional impairment. This is particularly true in childhood and adolescence. Understanding how…

This study examined the relationship between socio-demographic factors, screen media time usage, and light, moderate and vigorous activities on weekdays and weekends. Cross-sectional data was collected from 323 Spanish adolescents (mean age 13.59 years) who completed an interview administered recall questionnaire. Structural equation models…

Peer victimization can challenge mental health, yet limited research has considered contingent self-worth as a moderator of that relation. This study examined the relation of peer victimization to major depressive disorder, generalized anxiety disorder, and social phobia during adolescence, and contingent self-worth as a hypothesized moderator of…

This study examined the longitudinal relationship between self-esteem and body image distress, as well as the moderating effect of relationships with parents, among adolescents in Korea, using nationally representative prospective panel data. Regarding causal direction, the findings supported bi-directionality for girls, but for boys the…

The present study examined agreement between scores obtained from self-reports of behavioral and emotional problems obtained from 513 Algerian adolescents on the Youth Self-Report (YSR) with scores obtained from reports provided by their parents on the Child Behavior Checklist (CBCL). The correlations between self- and parent-report were larger…

Using group-based trajectory modeling, this study examined 5156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth to identify developmental trajectories of obesity from ages 6-18 and evaluate associations of such trajectories with risk behaviors and psychosocial health in adolescence. Four distinctive obesity…
