简要总结
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.
详细描述
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.

主要结局
Change from baseline: blood-oxygen-level dependent (BOLD) activation of anterior cingulate cortex as measured by functional magnetic resonance imaging
时间窗: Measured before and after the 13-week program
Difference in ACC BOLD activation to commission errors (contrast of BOLD response during commission errors vs. BOLD response during correct hits) will be tested using a 2 (Session: pre-SNAP vs. post-SNAP) × 2 (Group: treatment responders vs. non-treatment responders) within subject, mixed model analysis of covariance (ANCOVA), controlling for the effect of age, to investigate the two-way interaction between session and group. (Note: Commission errors compose a measure produced by the Go/No-Go task.)
