Children from disadvantaged families are at greater risk of developing regulation difficulties. Research suggests that family-level resources such as parental education or income are related to self-regulation development. However, most studies looking at the role of family resources have used single estimators of socioeconomic status or applied a composite score, neglecting that an interplay of resources may affect self-regulation outcomes. In N = 248 at-risk children (M[subscript age]: 65.7 months, 51% female), we examined the effect of economic, cultural, and social family resources on behavioral self-regulation in kindergarten. Results showed that family income, maternal education, and available help in child-rearing predicted the Head-Toes-Knees-Shoulders task performance. The results indicate that behavioral self-regulation is associated with different family resources beyond socioeconomic status.
