Parental autonomy-supportive practices and toddlers’ rule internalization: A prospective observational study

Motivational research conducted within self-determination theory suggests that autonomy-supportive (AS) parenting fosters rule internalization, while more controlling tactics hinder it. The goal of the present study is to examine how AS in a socialization context relates to toddlers’ internalization. Toddlers participated in a clean-up and a toy prohibition task at 2 and 3.5 years of age (T1: N = 102; T2: N = 85). Their parent’s disciplinary strategies were coded the first year. Toddlers’ committed compliance, indicative of rule internalization, was coded at both time points. After controlling for covariates and initial committed compliance, a linear regression was conducted to predict change in committed compliance over time. As expected, results reveal that parental AS strategies when toddlers were 2 years old were positively related to an improvement in committed compliance from 2 to 3.5 years of age, while controlling strategies predicted deterioration. This prospective, observational study suggests that supporting toddlers’ autonomy in socialization contexts fosters rule internalization.
