Trajectories of verbal and physical peer victimization among children with comorbid oppositional defiant problems, conduct problems and hyperactive-attention problems. Child Psychiatry and Human Development. 50(6): 1037–1048.
The high levels of comorbidity between oppositional/conduct problems and hyperactivity/attention problems underscore the need for assessing how vulnerability for peer victimization is shaped by overlap among these behavior problems. Children (mean age 8.39, SD = 0.93) participating in a longitudinal study of the development of conduct problems (N = 744; 348 girls) in Quebec, Canada, were evaluated by their teachers regarding experiences of peer verbal and physical victimization every year for 6 years. Parent and teacher ratings of clinically significant oppositional/conduct problems, and hyperactivity/attention problems, as well as cormorbid opposition defiant/conduct problems and hyperactivity/attention problems were regressed onto trajectories of verbal and physical victimization. While behavior problems (both alone and together) were associated with higher levels of verbal and physical victimization, some variation was observed across rater and type of victimization. Ultimately, these findings suggest the importance of adapting programming for reducing victimization to children with oppositional and conduct problems.
