Seventy-eight families with child diagnosed as oppositional-defiant or conduct-disordered were randomly assigned to basic videotape parent skills training program (GDVM) with or without broader-based, videotape treatment component (ADVANCE).

ADVANCE produced additional significant improvements in parents' communication, problem-solving skills, and consumer satisfaction, as well as children's increased knowledge of prosocial solutions.
