The effectiveness of the Incredible Years Parenting program was evaluated in a low-income sample of Caucasian, African American, Hispanic, and Asian mothers whose children were enrolled in Head Start. Data from two prior interventions studies [Webster-Stratton (1998) Journal of Consulting and Clinical Psychology, 66(5), 715-730; Webster-Stratton et al. (in press) Journal of Clinical Child Psychology] were combined, yielding a sample of 634 families (370 Caucasian, 120 African American, 73 Asian, 71 Hispanic) across 23 Head Start centers. Centers were matched and assigned randomly t either an experimental condition (8-12 weeks of weekly 2-hr parenting classes), or a control condition (the regular Head Start Program without parenting groups).
