Mothers and fathers completed a 7-item social competence scale adapted from Pettit, Harrist, Bates, and Dodge (1991) indicating how socially skilled the child was in several kinds of interpersonal interactions (e.g., understanding others’ feelings, generating good solutions to interpersonal problems). Items were rated on a 5-point scale from 1 = very poor to 5 = very good. A single scale was computed as the average of the 7 items.
