The Role of Supportive Parenting and Stress Reactivity in the Development of Self-Regulation in Early Childhood.

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]
