Among preschool-aged children, conduct problems (CP) are the number one reason for referral to mental health professionals. Research has consistently indicated that behavioral parent training (BPT) is the most effective technique for treating children’s disruptive behavior; however, there is a lack of research regarding BPT effects in children below the age of 3. Preventive behavioral parent training (PBPT) can be considered a preventive extension of BPT. The purpose of this study was to determine the degree to which PBPT might yield immediate effects in reducing rates of conduct problems (i.e., noncompliance and tantrums) displayed by typically developing young children. Overall, findings indicated that all four child participants displayed decreased rates of noncompliance and tantrums as predicted.
