Existing literature connects impulse control dysfunction to high-risk behaviors and negative life outcomes. Evidence-based interventions for children and adolescents who are at-risk or who are displaying significant levels of impulsive behavior are necessary in order to promote self-control, and in turn, positive life outcomes. This study investigated the impact of an eight-week, school-based GCBT intervention on cognitive inhibition and behavioral impulsivity in adolescent participants. The intention of the study was to evaluate the trend in inhibition and impulsivity from baseline to post-intervention assessments across five middle school students dually enrolled in a residential treatment facility and a center-based emotional support program. Although conclusive statements regarding the effects of the intervention program on the adolescent participants were unable to be made because of the small sample size and the absence of a control group, trends in the data suggest that the intervention had a positive impact on the behavior of four of the five student participants.
