Abstract
Parental self-efficacy (PSE) is a pivotal determinant of change in children's adjustment. However, not only has previous research shown that PSE plays a protective role for children's rule-breaking (RB) behaviours (i.e., parent-driven process), but RB also can reduce parents' PSE over-time (i.e., child-driven process). This study examined the bidirectional longitudinal associations between PSE and RB behaviours by disentangling maternal from paternal influences and between- from within-person effects. In the present seven-wave longitudinal study involving 200 Italian children (T1: M(age) = 9.80, SD = 0.65; 50.5% girls), their mothers (N = 200) and fathers (N = 190), two random-intercept cross-lagged panel models (one for mothers and one for fathers) were used to explore whether: (a) stable parts of PSE and RB were related to each other, (b) higher levels of PSE were associated with lower levels of RB at a given time point, and (c) higher levels of PSE at a given time point were associated with future lower levels of RB. Results provided evidence both for a parent- and a child-driven process between mothers' PSE and children's RB behaviours. However, these results were not replicated for fathers. Implications are discussed.
