Exposure to deviant friends has been found to be a powerful source of influence on children's and adolescents' aggressive behavior. However, the contribution of deviant friends may have been overestimated because of a possible non-accounted gene-environment correlation (rGE).

Adolescent stress-related growth refers to enhancement in an adolescent's cognitive-affective or social resources as a result of experiencing stressors. We tested whether adolescents reporting high levels of stress-related growth showed superior adaptation outcomes on a day-to-day basis. Participants (n = 91; females = 46, age = 14) completed a…

For many African Americans, racial identity is an important aspect of their individual identity. We explored developmental change and stability of individual differences in the racial centrality of African American youths and their mothers as well as the relation between maternal and child racial centrality across time. African American youths (N…

Although spending time in criminogenic settings is increasingly recognized as an explanation for adolescent delinquency, little is known about its determinants. The current study aims to examine the extent to which (change in) self-control and (change in) delinquent attitudes relate to (change in) time spent in criminogenic settings, and the…

This longitudinal study aimed to differentiate between acculturative and developmental processes by (a) comparing levels and change rates in victimization among ethnic German immigrants and native German adolescents in Germany and Russian Jewish immigrants in Israel, and (b) testing whether interindividual differences in victimization among…

In order to enhance our understanding of interindividual differences in academic motivation, the present study examined the interplay of personality, psychosocial adjustment and socio-academic factors in a subsample of adolescent students identified as teacher-and-peer-independent motivation type (MT) (N = 295; M[subscript Age] = 13.71) in…

Person-centered analyses of achievement goals have been scarce in studies of elementary school children. In this investigation, the authors examined the natural combinations of achievement goals (mastery, performance-approach, performance-avoidance) among 3rd grade students (N = 195) and how clusters differed in self-, teacher-, and peer-reported…
