Large group community-based parenting programs for families of preschoolers at risk for disruptive behaviour disorders: utilization, cost effectiveness, and outcome.
A significant percentage of children with disruptive behavior disorders do not receive mental health assistance . Utilization is lowest among groups whose children are at greatest risk . To increase the availability , accessibility , and cost efficacy of parent training programs , this prospect i ve r and omized trial compared a large group community-based parent training program to a clinic-based individual parent training ( PT ) programs .  All families of junior kindergartners in the Hamilton public and separate school boards were sent a checklist regarding problems at home . Those returning question naires above the 90th percentile were block r and omly assigned to : ( 1 ) a 12-week clinic-based individual parent training ( Clinic/Individual ) , ( 2 ) a 12-week community-based large group parent training ( Community/Group ) , or ( 3 ) a waiting list control condition .  Immigrant families , those using English as a second language , and parents of children with severe behaviour problems were significantly more likely to enroll in Community/Groups than Clinic/Individual PT . Parents in Community/Groups reported greater improvements in behaviour problems at home and better maintenance of these gains at 6-month follow-up . A cost analysis showed that , with groups of 18 families , Community/Groups are more than six times as cost effective as Clinic/Individual programs
