Longitudinal changes in trusting behavior across adolescence and their neural correlates were examined. Neural regions of interest (ROIs) included the medial prefrontal cortex (mPFC), dorsal anterior cingulate cortex (dACC), left anterior insula (AI), bilateral ventral striatum (VS), and right dorsal striatum (DS). Participants (wave 1 age: M =…

We investigate how context might influence adolescent boys' and girls' ambition and the impact of gender role conformity and social status. Adolescent participants (N = 270) reported their ambition in one of three experimentally manipulated contexts: future education, future work, or a control. Boys experienced a significant negative drop in…

Identity research focuses on multiple processes capturing how adolescents form and maintain a sense of self. However, identity content (the "what" of identity) might impact associations between identity and the association with well-being. We examined this potential role of content (i.e., valence and life domain) in two studies, focusing…

The sustainability motive-alignment hypothesis posits that adolescents will be motivated to act sustainably when they view sustainable behavior as aligned with their motives for autonomy and peer status. Based on this hypothesis, we developed the Sustainability Motive-Alignment Scale (SMAS), a brief self-report scale of individual differences in…

This study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted…

Current theories of loneliness posit that biases in social information processing play a key role in the development and maintenance of loneliness. However, this assumption has rarely been tested in longitudinal research in adolescence. The current study concentrated on two constructs associated with such biases, that is, fear of negative…

Callous-unemotional (CU) traits predict behavioral problems in adolescence. But little is known about early modulatory factors. Behavioral Inhibition (BI) in particular has been suggested to protect against the development of CU-traits. This temperamental predisposition is characterized by heightened environmental sensitivity. The current…

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,…

This original paper, based on data from the Erasmus+Blurred Lives Project, presents a new multi-dimensional categorisation model to describe negative online experiences, including forms of cyberbullying, based on a study of internet usage among over N = 2,500 adolescents with lower socio-economic status (SES) backgrounds across five European…

Psychoeducation programs may increase knowledge about stress and help adolescents cope with stress. However, research about the effectiveness of psychoeducation programs about stress for adolescents is limited. The present study aimed to fill this gap by evaluating the effect of a brief school-based universal psychoeducation program about stress,…

There has been little attention to personality in research on school refusal (SR). This study examined personality traits among 41 adolescents receiving cognitive-behavioral therapy (CBT) during participation in a School Refusal Program in the Netherlands. Traits were examined via clinical scales and 2-point code types derived from the Minnesota…

Background: Adolescents with mild-to-borderline intellectual disability face peer resistance challenges, risking harmful or dangerous situations. Method: We designed a peer resistance group intervention at school for adolescents with mild-to-borderline intellectual disability, tested its feasibility (N = 4, M[subscript age] = 14.1, M[subscript IQ]…

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 multisample longitudinal study examined the directionality of effects between identity exploration and commitment processes and depressive symptoms across adolescence. We compared two theoretical perspectives. According to the vulnerability model, identity uncertainty predicts depressive symptoms, whereas the scar model holds that depressive…

Pornography consumption at a young age may pose a threat for sexual health, due to the presence of aggression and the degradation of women. Sexuality education is viewed as a way to mitigate the effects of inadequate information and counteract certain tendencies that may be learned from pornography. This study involved a systematic review of…
