Description

This is a program to monitor families with boys aged seven to nine who attend elementary school, in order to reduce antisocial behavior in the short and long terms.
The program provides training for parents, focusing on the development of social skills and self-regulation in children, and home visits in cases of family crisis.

Impact evaluations

Impact assessment studies have shown different effects at different stages of children’s development throughout their lives. At the age of 15, there was no impact on the following factors: adaptation to school; disruption in the classroom; self-reported delinquency; offenses followed up by the juvenile court; perception of parenting styles [1].
At the age of 24, there was a positive impact on the levels of university education and reduction of delinquent behavior [2], and at the age of 28, there was a positive impact on the reduction of violence against people and crimes against property [3].
