Research Findings: The objective of this research was to evaluate the effectiveness of Incredible Years Basic Parent Training (IYPT Basic) in a community clinic setting in Hong Kong. IYPT Basic is a Western program developed to promote children's academic, social, and emotional regulation skills and to reduce conduct problems among typically developing children. The program has not been tested in non-Western cultures, where the challenges for parents of children with developmental disabilities can be different. The IYPT Basic was adapted slightly to accommodate cultural characteristics in Hong Kong. Parents of 52 preschoolers with developmental disabilities were randomly assigned to either the IYPT Basic or a waitlist control. Parent and child dyads were assessed before and after the 12-week intervention/waitlist period via self-reports and spouse/kin reports and videotape coding by observers blind to the intervention/waitlist status. Significant intervention benefits included (a) increase in positive and reciprocal parent-child interaction, (b) reduction in parental stress, and (c) decrease in oppositional behavior among the children. The parents' attendance, satisfaction, and homework compliance was high. Practice or Policy: IYPT Basic, when implemented with cultural sensitivity, can be effective for--and well received by--Chinese parents of preschoolers with developmental disabilities in a community setting.
