The Montreal Preventive Treatment Program was designed to prevent antisocial behavior of boys who display early problem behavior. It provides training for both parents and youth to decrease delinquency, substance use, and gang involvement. The intervention has been successfully implemented for white, Canadian-born males, ages 7–9, from low socioeconomic families, who were assessed as having high levels of disruptive behavior in kindergarten.
The Preventive Treatment Program combines parent training with individual social skills training. Parents receive an average of 17 sessions that focus on monitoring their children’s behavior, giving positive reinforcement for prosocial behavior, using punishment effectively, and managing family crises. The boys receive 19 sessions aimed at improving prosocial skills and self-control. The training is implemented in small groups containing both disruptive and nondisruptive boys, and it utilizes coaching, peer modeling, self-instruction, reinforcement contingency, and role playing to build skills.
Evaluations of the program have demonstrated both short- and long-term gains for youth receiving the intervention. At age 12, three years after the intervention:
- Treated boys were less likely to report the following offenses: trespassing, taking objects worth less than $10, taking objects worth more than $10, and stealing bicycles.
- Treated boys were rated by teachers as fighting less than untreated boys.
- 29 percent of the treated boys were rated as well-adjusted in school, compared to 19 percent of the untreated boys.
- 22 percent of the treated boys, compared to 44 percent of the untreated boys, displayed less serious difficulties in school.
- 23 point three percent of the treated boys, compared to 43 percent of the untreated boys, were held back in school or placed in special education classes.
At age 15, those receiving the intervention were less likely than untreated boys to report:
- Gang involvement.
- Having been drunk or taken drugs in the past 12 months.
- Committing delinquent acts (stealing, vandalism, drug use).
- Having friends arrested by the police.
