Concurrent and prospective effects of income, adversity, and parenting behaviors on middle‐childhood effortful control and adjustment

Abstract This study examined whether effortful control (executive control [EC], delay ability [DA]) accounted for the effects of early‐childhood contextual factors (income, cumulative risk, parenting) on middle‐childhood adjustment (social competence, internalizing and externalizing problems), or whether contextual factors account for observed associations between effortful control and adjustment. A sample of children and parents ( N = 306) were assessed when children were 3‐, 5‐, and 8‐years. Age‐3 income and cumulative risk predicted changes in age‐8 EC. Also, age‐3 parenting predicted changes in effortful control. Warmth and limit setting predicted increases in EC, whereas negativity predicted decreases in DA from the age of 3 to 5, and scaffolding predicted increases in EC and DA from the age of 5 to 8. In turn, age‐8 EC was associated with higher social competence. However, neither age‐8 EC nor DA was associated with internalizing or externalizing above the effects of age‐8 stress (negative life events). The findings indicate that early‐childhood income, adversity, and parenting are relevant in predicting effortful control development into middle‐childhood, and in turn, middle‐childhood social competence. However, concurrent stress appears more relevant to adjustment problems, implying some of the effects of effortful control might be accounted for by the context of risk.
