Ontario Child Health Study: correlates of disorder.

Data from the Ontario Child Health Study were used to examine the prevalence and selected correlates of conduct disorder, hyperactivity, emotional disorder, and somatization in children 4 to 16 years of age by informant (parent and teacher for children 4 to 11, and parent and youth for children 12 to 16). The results indicate that the prevalence and pattern of correlates of the individual disorders differ in important ways by informant. This suggests that we need to understand the factors that influence assessments provided by informants from different contexts (e.g., parents and teachers) before combining information from them to arrive at singular classifications.
