Introduction: The Moral Foundations Theory (MFT) identifies innate moral foundations that drive moral judgment, and are assumed to mature at different phases throughout development. However, core developmental aspects of moral foundations, such as normative age and gender differences from an MFT perspective, remain relatively unexplored,…

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…

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…

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…

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…

This study aims to examine the impact of a school-based intervention on life skills and personal development among adolescents in Kosovo. It responds to the educational shift toward competence-based learning outlined in the new Kosovo curriculum. The research adopts a quasi-experimental design with pre-and post-tests to examine changes in…

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…

Friendships are important sources of support during adolescence. However, a growing literature indicates some adolescents co-ruminate, or talk with friends about problems in a way that is excessive, speculative, and negatively focused, which confers risk for internalizing problems. Still, previous research had not examined the types of problems…

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…

This paper addresses a validation study focusing on the process of adapting the EPOCH measure of adolescent well-being (Kern et al. in Psychol Assess 28(5):586-597. https://doi-org.bibliotheek.ehb.be/10.1037/pas0000201, 2016) to the school context and translating it into German--resulting in the EPOCH-School model (EPOCH-S) with the corresponding measure EPOCH-G-S…

Nigerian adolescents are facing increasing rate of parental separation, which is affecting their overall development, including good mental health. Various studies have examined the impact of parental separation on the self-esteem of adolescents. Outcomes of such studies are elaborate, complex and intricate; hence the need for this inquiry. The…

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents' prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the…
