This chapter provides a description of a videotape and research-based parent training program designed to prevent and treat conduct problems in young children, 3 to 8 yrs old. The program was designed with the broad goals of (a) strengthening parenting competence, especially the use of nonviolent discipline approaches; (b) increasing positive family support networks and school involvement; (c) promoting child social competence; and (d) decreasing child conduct problems. Other topics discussed include: parent training methods; parent training process; and therapist strategies. The authors contend that the process of collaboration between therapists and parents is key to the success of parenting programs.
