Although previous research has corroborated the independent contributions of parent personality and adolescent temperament in predicting adolescents’ externalizing behavior problems (EXT), few studies have examined their joint contribution to predict EXT in adolescence. In the present longitudinal study, first we examined the developmental trajectory of EXT from ages 12 to 14, and, next, we investigated the joint effects of mothers’ irritability and adolescents’ inhibitory control (IC) in predicting the developmental trajectory of EXT.

Bidirectional relations among adolescents' positivity, perceived positive school climate, and prosocial behavior were examined in Colombian youth. Also, the role of a positive school climate in mediating the relation of positivity to prosocial behaviors was tested. Adolescents (N=151; M-age of child in Wave 1=12.68, SD=1.06; 58.9% male) and their parents (N=127) provided data in two waves (9months apart). A model of bidirectional relations between positivity and perceived positive school climate emerged.
