Ways in which adults can work with noncompliant, defiant, or oppositional children are presented in this manual. The program presented here was designed to help children having at least a two-year level of language or general cognitive developmental level and who fall between the ages of 2 and 12 years. The methods are meant for use by experienced clinicians with training in delivering psychological services to families of defiant children. The guide sets forth detailed instructions for conducting clinical evaluations and provides a set of interview forms and behavior rating scales that may be used by clinicians. The manual specifies step-by-step procedures to follow in conducting an empirically validated program for training parents in the management of behavior-problem children. It provides a set of parent handouts to be used during the course of the program. The program aims to improve parental management skills and competence in dealing with child behavior problems, to increase parental knowledge of the causes of childhood defiant behavior, improve child compliance, and increase family harmony.
