The Development of Pure vs. Co-Occurring Externalizing and Internalizing Symptomatology in Children
Year: 2006
Type: article
Study design: Observational Study
Abstract: The overarching goal of the present study was to test the validity of a model that proposes why some children are likely to not develop co-occurring problem behavior. Specifically, it was hypothesized that high and persistent levels of specific subtypes of internalizing (i.e., social anxiety, inhibition, and withdrawal) or externalizing symptomatology (impulsivity/hyperactivity, aggression, and anger reactivity) during middle childhood would prevent the development of co-occurring disorders during early adolescence. These issues were examined among a sample of 260 low-income boys followed from age five to twelve. Overall, the results failed to support the proposed model, that high and persistent levels of narrow-band constellations of internalizing and externalizing symptoms would prevent the development of a co-occurring disorder. Instead, the results were consistent with three prevailing theories of co-occurring disorders: 1) shared risk factors; 2) general, non-specific expression of psychopathology; and 3) heightened maladjustment.
