Impact Evaluation of an Addiction Intervention Program in a Quebec Prison

This study evaluates the effects of a prison-based addiction intervention program. The evaluation is based on a multidimensional data collection that draws a portrait of the respondents' substance use, and of their psychological/emotional, social, and judicial spheres. It measures the changes, or lack thereof, in substance use; the psychological/emotional, social, and judicial spheres; as well as the post-treatment services used.

A quasi-experimental repeated measures design (0, 6 weeks, and 6 months) was used. Effects of the program were identified by comparing the results obtained by a group of inmates who had participated in the program (n = 80; experimental group) with those of another group who had received no intervention (n = 70; control group).

The preliminary results suggested a certain treatment effect related to impulsivity and psychological distress.

Although the preliminary results were promising, the experimental and control groups did not differ significantly when more robust analyses were used.
