Maternal sensitivity and supportive discipline are important determinants of child self-regulation. Some evidence suggests that specific genetic or temperamental markers determine children's susceptibility to the impact of maternal parenting on child self-regulation. Cortisol reactivity as a susceptibility marker moderating the relation between maternal parenting and child self-regulation has not yet been studied. In this longitudinal population-based study (N = 258), the moderating role of infant cortisol stress response to the Strange Situation Procedure at age 1 was examined in the association between parenting (sensitivity and supportive discipline) at age 3 and child self-regulation at age 3 and 4. Maternal sensitivity and supportive discipline were related to child immediate and prolonged delay of gratification at age 3, and maternal sensitivity was related to working memory skills at age 4. No evidence of differential susceptibility to maternal parenting was found, based on differences in infant cortisol stress response. Highlights: Maternal sensitivity and supportive discipline relate to child immediate and prolonged delay of gratification at age 3. Maternal sensitivity is related to child working memory skills at age 4. No evidence was found for differential susceptibility to maternal parenting based on child stress reactivity. Our findings emphasize the importance of parental socialization for the development of self-regulatory functions in children. [ABSTRACT FROM AUTHOR]

Parenting stress of mothers has frequently been linked to negative child outcomes. According to Abidin's stress model, this relationship may be explained by dysfunctional parenting behaviors. In this study, we scrutinized the effects of both mothers and fathers in the pathway from parenting stress through parenting behaviors to subsequent adolescent behavior problems. We expected the association between parenting stress and adolescent behavior problems to be partially mediated by maternal and paternal parenting behaviors. Further, we expected crossover effects, i.e., that parenting stress of one parent was related to the parenting behavior of the other parent. We applied a 3-wave longitudinal design using data from 441 adolescents (52% girls) and their parents (419 fathers; 436 mothers). Parents reported on parenting stress (adolescent age range = 10.9–16.3 years). Adolescents reported on perceived parental overreactivity and warmth (age range = 12.9–18.3) and their own internalizing and externalizing problems (age range = 15.9–21.3). Despite cross-sectional significant associations between parenting stress, parenting behavior, and adolescent behavior problems, we found no evidence of longitudinal linkages. One exception was maternal parenting stress, which positively predicted later adolescent externalizing problems. Consequently, the mediating role of parenting behaviors was not supported. We found no crossover effects in the pathway from parenting stress to parenting behaviors. The discrepancies between our longitudinal and cross-sectional findings raise questions about the actual impact that parents have on their children's outcome. Though, targeting mothers' parenting stress may help to reduce adolescent externalizing problems and its ramifications at least to some extent. Highlights: This study tested Abidin's stress model from a family systems perspective, using 3-wave longitudinal data from mothers, fathers, and adolescents. Clear cross-sectional but few longitudinal linkages were found between parenting stress, parenting behavior, and adolescent behavior problems. Only maternal parenting stress was related to later adolescent externalizing problems, but not to internalizing problems nor parenting behaviors. These nuanced findings raise questions about the actual impact that parents have on their children's outcomes. We recommend further longitudinal research to unravel any bidirectional influences between mothers, fathers, and adolescents. [ABSTRACT FROM AUTHOR]
