Investigating Psychosocial Intervention Treatment Response in

Status Completed

Clinical Trial Summary

This research focuses on youth with conduct disorder (CD), and a history of violence. CD is a youth neurodevelopmental disorder that is commonly associated with criminality. Although psychosocial interventions that address impulsivity and self-control have been shown to be effective at helping promote prosocial behavior in patients with CD, the biological changes that occur as a result of treatment are not well understood. This study will explore changes in the brain function of the anterior cingulate cortex (ACC) in response to a common psychosocial intervention (Stop, Now and Plan). This study will contribute to our understanding of biological mechanisms involved in therapeutic gains among children with behavioural problems and youth offenders; therefore, it will inform further development of treatment programs for children/youth with impulsive behaviours.

Clinical Trial Description

CD is a youth-limited neurodevelopmental disorder characterized by impulsivity and dysfunctional social behavior. CD is associated with increased risks of mortality, lower educational and occupational achievement, criminal behavior and other psychosocial difficulties, and hence presents a significant burden to society. Impulsivity is a prominent predictor of violence in CD. Treatment programs targeting impulsivity in CD have been shown to be effective at increasing pro-social functioning in CD, but the biological mechanisms that underpin these therapeutic gains are not well understood. Past research suggests that the ACC play a role in CD and impulsivity. This study explores biological and behavioral changes in response to Stop, Now and Plan (SNAP), a validated 13-week psychosocial intervention addressing impulsivity and self-control in youth. The main hypotheses are: (1) CD youth who respond to SNAP treatment will exhibit greater post-treatment ACC activation during an fMRI imaging task compared with their baseline, pre-treatment ACC activation. The secondary hypotheses are: (1) CD youth will exhibit lower ACC activation at baseline during an fMRI imaging task compared with the baseline ACC activation exhibited by typically developing youth. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
