Socioemotional functioning across the transition to lower secondary school: The role of temperament and relationships with mothers and teachers.

This Finnish longitudinal study investigated the role of relationships with mothers (n = 631) and teachers (n = 56), and adolescents' (n = 848; 53.9% girls, 46.1% boys) temperament in the development of the adolescents' socioemotional functioning during the transition to lower secondary school (Grade 6 to Grade 7; age in Grade 6: M = 12.32, SD = 0.36). The results showed that mother-adolescent closeness predicted a higher level and teacher-adolescent closeness predicted a smaller decrease in prosocial behavior. Teacher-adolescent conflict predicted a higher level, and mother-adolescent conflict predicted an increase in externalizing problems. Only temperament predicted internalizing problems. In addition, relationship quality both mediated and moderated some of the associations between temperament and socioemotional functioning.
