| Abstract: | We examined whether a preschool intervention program moderates the effects of perinatal complications with a sample of boys from the most disadvantaged areas of Montreal (Canada). Some boys experienced the preschool program and some did not, which allowed us to test whether the program had any effects on the boys' risk for early adolescent delinquency given their perinatal histories. We hypothesized that perinatal complications would place boys at significantly greater risk for antisocial behavior during early adolescence and that participation in a preventive preschool program might circumvent this risk. Independent of maternal sociodemographic characteristics, boys with a history of perinatal complications showed no greater risk of reporting delinquency during early adolescence than their same-sex peers without a history of perinatal complications. Surprisingly, the program showed a beneficial effect on boys with no history of serious perinatal complications. Such boys were less at risk for delinquency. In the presence of a serious medical condition after birth, the benefits of the program decreased significantly to the point that it placed the boys at risk. |
