Families and Schools Together (FAST) is an early-intervention/prevention, collaborative, school-based, multifamily family-support program for elementary school children who have been identified by their teachers as having behavior problems. The program integrates concepts and practices of community organizing with effective clinical techniques based on family therapy and play therapy. Parent–professional partnership is used to engage low-income and isolated families into the eight-week program. Process and outcome evaluation indicate that children show statistically significant improvements in conduct disorder, anxiety/withdrawal, and attention span over time. In addition, two-year follow-up data suggest that child-functioning gains are maintained and that FAST parents become more involved at school, regularly see their FAST friends, begin employment after being on welfare, return for further education, and become involved in the community.
