Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Conduct Disorder

Participants are justice-involved youth with conduct disorder. Participants will receive Stop, Now and Plan (SNAP) psychosocial intervention.

Group Type EXPERIMENTAL

Stop, Now and Plan

Intervention Type BEHAVIORAL

SNAP program was developed to target justice-involved youth (6 years and older) who have problems with aggression, CD, and/or gang affiliation. SNAP focuses on engaging youth in interesting and creative learning modules by providing real life scenarios designed to improve self-control, impulsive behaviors, decision-making skills, and pro-social skills. SNAP treatment is delivered over a 13-week period.

Control

Participants are healthy males. Participants receive no intervention.

Group Type NO_INTERVENTION

No interventions assigned to this group
