Parent behavioral training to modify child noncompliance: Effects on untreated siblings

The purpose of the present study was twofold: (a) to examine changes in parent behavior toward an untreated sibling after parent behavioral training to modify a target child's noncompliance and (b) to examine changes in the untreated sibling's behavior. Eight clinic- referred children and their mothers served as the subjects. Parent training consisted of the use of a standardized clinic program to modify child noncompliance. The outcome measure was home observations of the parent and untreated child's interactions. The results indicated significant changes in both the parent's behavior and the untreated sibling's noncompliance.
