The study analysed a sample of male youth correctional discharges within Manitoba from January 1, 2000 to December 31, 2000. Agassiz Youth Centre (AYC) discharges were compared to a matched sample of discharges from other institutions using archival data (N = 150). Subsequent numbers of charges, convictions, months incarcerated and times incarcerated from each group were examined over two years in order to assess the effectiveness of AYC's Positive Peer Culture (PPC) program. These variables were compared while controlling for age, race, education, place of residence, family background, gang affiliation, type of offence, seriousness of most serious offence, number of times incarcerated, past risk of suicide, and risk to reoffend. Results suggest that PPC does have a significant impact on certain measures of recidivism including total number of times incarcerated, total number of months incarcerated, seriousness of the most serious offence and time before reinvolvement. Exploratory analysis also measured PPC's comparative effect on offenders with different personal characteristics. Results suggest that youth who live in rural areas, who do not have a history of suicide risk, who reside with at least one parent, or who are a low risk to reoffend had better outcomes if they were discharges from AYC than from the comparison group. Although this study is unable to isolate all confounding variables, it will be able to give some insight into the effect of PPC on recidivism. Recommendations address the application and interpretation of PPC at AYC as well as the direction for future research. An extensive literature review is also included.
