The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth…

Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS)…

This study analyzed the factorial structure of motor competence tests designed to evaluate motor development among adolescents, focusing on the two main dimensions of coordination and motor control. To this end, we randomly sampled 1,026 adolescents (45.3% males; 45.7% females, age 13.75 years, SD = 1.28). Participants completed the…

Developmental changes in self-regulation are theorized to underlie adolescents' engagement in risky behaviors, physical health, mental health, and transition to adulthood. Two central processes involved in self-regulation, self-management (i.e. planning, concentration, and problem-solving) and disinhibition (e.g. distractibility and impulsivity)…

This study using PROSPER data (N = 977, age 11.5-age 15) investigated the longitudinal within-family associations between parent reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between…

It has long been assumed that children and adolescents want to be with their peers and therefore make active efforts to engage with them. However, a sizable minority of youth avoid peers for internal reasons (e.g., anxiety, preferences for solitude) or because they are socially withdrawn. Although by definition, withdrawn youth tend to stay away…

This study coordinates moral value development in adolescence, parenting style, and gender with issues of stability and specificity. The primary research question asked whether parenting styles of mothers and fathers influence the development of adolescent moral values, and secondary research questions asked whether adolescent moral values were…

At what ages are young people most open to political influence? We test the "formative years" model that underscores the importance of childhood experiences for political development against the "impressionable years" model that asserts the primacy of lessons learned during adolescence. To assess the relative merits of these…

Despite ample research on empathy development, its social origins have been understudied, particularly in the context of peer relations. This two-wave study of Swedish adolescents (N = 318; M[subscript ageT1] = 16.28, SD = 0.49; 55% females) examined longitudinal associations between youth friendships and empathy. The results showed that…

Economic growth is dependent on well-skilled human capital. Technical and Vocational Education and Training (TVET) programmes are paramount in provision of the requisite capabilities which encompass both academic and non-academic skills also known as whole youth development (WYD) skills. Youths leaving training institutions in Kenya experience…

The pervasiveness of racism in the U.S. and its negative relations with key development outcomes has led researchers to uncover mediators, of which this article argues efficacy should be considered. Self-efficacy, one's belief in their capability to accomplish a task or goal, can be measured in multiple domains of functioning and contexts to…

This study aims to investigate gender differences in effective parenting strategies for adolescent mathematics achievement growth, taking into account socioeconomic status (SES), based on a bioecological model. Latent growth curve modeling examines longitudinal data (n = 4163) from the Taiwan Education Panel Survey. The analysis reveals that…

Adolescents navigate the transition into young adulthood through their pursuit of developmental goals. While societal expectations and institutions provide normed paths to adulthood by shaping decisions on goal identification, individuals take various routes to attain adult-status through different goal prioritization. Using longitudinal data from…

Gender differences in non-cognitive abilities are important in explaining the "female advantage" in education. The existing literature, however, has not yet given a clear answer as to why gender differences in non-cognitive skills arise. Based on the theoretical perspective of social interaction, this research analyses how parenting…

We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…
