Increasing numbers of children being referred for mental health services are exhibiting problematic behaviors that can be subsumed under the category of Disruptive Behavior Disorders. This study with its foundations in a post-positivist approach was designed to explore treatment effectiveness of cognitive behavioral intervention applied to adolescents at Oak Grove Institute, a residential treatment facility. This study hypothesized that Wexler's PRISM Model, with its integration of affect, would be instrumental in modifying disruptive behavior as measured at Oak Grove Institute. Although the small sample size precluded statistically significant findings, there were interesting results with respect to two dependant variables. Findings approached significance on measures of impulsivity and verbal aggression. That is, impulsivity and verbal aggression scores were lowered.
