A key component of Mode Deactivation Therapy (MDT) is the development of self-awareness and regulatory skills by the client with the aim of helping adolescent males with conduct disordered behaviors, including sexually inappropriate behaviors and emotional dysregulation. The goal includes altering specific behaviors to fall within socially acceptable norms. In MDT the intervention of Validation-Clarification-Redirection (VCR) is the fulcrum of the transformation of detrimental learned beliefs about the adolescents' environment that manifest destructive behaviors into ideas about the world and those in it, into functional beliefs that are more balanced and lead to more compliant behaviors. While evidence suggests that this is the mechanism of change, a study specifically identifying the impact of the introduction and use of this skill has not been conducted to date. The purpose of this study was to examine the effect of MDT in both meta-analysis of total outcome versus Cognitive Behavioral Therapy (CBT) and mediation analysis of the VCR variable of MDT. The population includes adolescents with co-existing problems of conduct, opposition personality traits and history of trauma.
