The study investigated age-related trends in moral identity goal characteristics, as proposed in previous research (Krettenauer, 2022a), by modifying the Self-Importance of Moral Identity Questionnaire (Aquino & Reed, 2002). Internally and externally motivated moral identity was assessed on varying levels of abstractness for promotion…

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term…

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…

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 investigated how parents' value-based enculturation and acculturation processes (i.e., Mexican American and mainstream American values trajectories across their youths' development from late childhood to middle adolescence) related to their youths' behavioral, affective, and cognitive components of bicultural competence in late…

The role of early child care experiences on the development of the mother--child attachment relationship has been studied extensively. However, no prospective studies of early child care have addressed how these experiences might be reflected in the content of attachment representations during adolescence and beyond. The goal of this study was to…

Using data from the first national probability sample of Black, White, and Latinx sexual minority people in the United States, we examined whether and how sexual identity development timing and pacing differs across demographic subgroups at the intersections of cohort, sex, sexual identity, and race/ethnicity. Among a sample of 1,491 participants…

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 longitudinal follow-up studied continued effects of parental influences on narrative identity in young adulthood. Decades of research have shown the importance of parental shared reminiscing and positive parenting for the development of children's and youths' autobiographical memory and narrative identity. Yet, research on long-term…

A central assumption of identity theory is that adolescents reconsider current identity commitments and explore identity alternatives before they make new commitments in various identity domains (Erikson, 1968; Marcia, 1966). Yet, little empirical evidence is available on how commitment and exploration dynamics of identity formation affect each…

Executive functions (EFs)--the higher level cognitive abilities that enable us to control our own thoughts and actions--continue to develop into early adulthood, yet no longitudinal study has examined their stability during the important life transition from late adolescence to young adulthood. In this twin study (total N = 840 individuals from…

The aim of this study was to test a model of emotional distress, which incorporates the potential mediator role of positive resources (sense of control, self-esteem, and optimism) in the association of age with emotional distress. The study used a cross-sectional design with intentional sampling and the voluntary participation of 325 adults…

Despite the importance of community service for the well-being of individuals and communities, relatively little is known about the developmental course of community service during the transition to adulthood (TTA). This study tested competing hypotheses about change in community service across the TTA by estimating latent growth models from Ages…

This study investigated the effects of internal and demographic variables on civic development in late adolescence using the construct "civic purpose." We conducted surveys on civic engagement with 480 high school seniors, and surveyed them again 2 years later. Using multivariate regression and linear mixed models, we tested the main…

Adolescents' intergenerational narratives--the stories they tell about their mothers' and fathers' early experiences--are an important component of their identities (Fivush & Merrill, 2016; Merrill & Fivush, 2016). This study explored adolescents' intergenerational narratives across cultures. Adolescents aged 12 to 21 from 3 cultural…
