(2015) Over-time associations among parental self-efficacy, promotive parenting practices, and adolescents' externalizing behaviors concerning the associations over time. Theory predicts three types of processes relevant to these associations: a PSE-driven process, a parent behavior-driven process, and a child-driven process.In this study, we tested these processes during early to middle adolescence using reports from 401 mothers and fathers from 305 families, and their adolescents (Mage = 11.5), at three time points. Cross-lagged panel models were used to examine the associations among PSE, promotive parenting practices, and adolescents' externalizing. Results supported a PSE-driven process for mothers within early adolescence. Additionally, evidence for parent behavior-driven and child-driven processes emerged at different times within this developmental period.
