Psychosocial Functioning Among Inmates in Prison-Based Drug Treatment: Results from Project BRITE

To assess the impact of a positive behavioral reinforcement intervention on psychosocial functioning of inmates over the course of treatment and on post-treatment self-reported measures of treatment participation, progress, and satisfaction.

Male (n = 187) and female (n = 143) inmates participating in 12-week prison-based Intensive Outpatient (IOP) drug treatment were randomly assigned to receive standard treatment (ST) or standard treatment plus positive behavioral reinforcement (BR) for engaging in targeted activities and behaviors. Participants were assessed for psychosocial functioning at baseline and at the conclusion of treatment (post-treatment). Self-reported measures of treatment participation, treatment progress, and treatment satisfaction were also captured at post-treatment.

The intervention affected female and male subjects differently and not always in a way that favored BR subjects, as compared to the ST subjects, most notably on measures of depression and criminal thinking.

Possible explanations for the results include differences in the male and female custody environments combined with the procedures that study participants had to follow to earn and/or receive positive reinforcement at the two study sites, as well as baseline differences between the genders and a possible floor effect among females on measures of criminality. Limitations of the study included the inability to make study participants blind to the study conditions and the possible over-branding of the study, which may have influenced the results.
