Early-onset conduct problems: Does gender make a difference?

Baseline assessments of 64 girls and 158 boys (aged 4-7 years) diagnosed with oppositional defiant disorder (ODD) or early-onset conduct problems, or both, were examined for gender-linked differences in behavioral symptoms. Child variables, parenting variables, and family variables were correlated with teacher reports of externalizing problems at school and independent observations of externalizing problems at home before treatment to determine whether there were any gender-specific differences in risk factors. Follow-up data (1-2 years posttreatment) were also examined for any gender differences in predictors of treatment outcome. Results indicated significant gender differences in behavioral symptoms according to independent home observations. However, reports of gender differences in behavioral symptoms were influenced by the gender of the reporting agent. The only gender-specific risk factor found was father ''negativity,'' which was correlated with boys' behavior at home but not girls' behavior. Concerning differences in treatment outcome, variables regarding parents' psychological states and parenting style were the best predictors for girls but not for boys.
