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…

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…

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…

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…

The current study suggested and tested a model to investigate the associations between adolescent future expectations of work and education (AFE-WE; adaptive responses) and positive future expectations (PFE; adaptivity) through concern, control, curiosity, and confidence (adaptability resources) as well as the role of the gender. The data were…

This study quantified changes in self-reported sexual orientation from adolescence to early adulthood, and whether childhood gender nonconformity (GNC) predicted sexual orientation changes. Youth (2,678 boys and 3,359 girls; 96.09% ethnically White) from the Avon Longitudinal Study of Parents and Children (ALSPAC) were included. Self-reported…

Little is known about adolescent applications of the virtues such as honesty, responsibility and courage across different cultural contexts. Using the Adolescent Intermediate Concepts Measure we analyze samples of adolescents (ages 12 to 20; N = 9,112) from 5 contexts: North Macedonia, Mexico, Taiwan, the United Kingdom, and the United States.…

The theory of mind (ToM) is the ability to understand mental states in others. The previous research has highlighted age- and language-dependent effects during childhood and provided inconsistent data regarding the role of gender. Notably, these variables were rarely studied simultaneously among adolescents. Accordingly, this short longitudinal…

Background: Despite extensive research examining features of adolescents' ego-identity development, little research has demonstrated patterns of ego-identity development and its relationship with various individual and environmental factors that are theoretically important for identity development. Objective: The current study investigated…

This study aims to determine whether assertiveness predicts restriction anxiety, separation anxiety and expectation of rejection, which are the sub-dimensions of Separation-Individuation Test of Adolescence. The study was conducted with high school students in a Central Anatolian city during the second semester of the 2018-2019 academic year. A…

This study examined the association of friendships and popularity with adolescents' first-time involvement in a romantic relationship (referred to as romantic relationship debut). The aim of this article was twofold: first, to disentangle the unique effects of friendships and perceived popularity; second, to separate same- and cross-gender peer…
