Although I don’t have any suggestions regarding a specific form, studies do indicate that client satisfaction in general is associated with better drug treatment outcomes.  Not sure if this applies to clients who are also inmates.  Check out the following from : J Health Psychol.

Patient Satisfaction and Sustained Outcomes of Drug Abuse Treatment

ZHIWEI ZHANG, DEAN R. GERSTEIN, and PETER D. FRIEDMANN

Abstract

The authors investigated the relationship between patients’ self-rated satisfaction with treatment services during and shortly after treatment with their drug use outcomes at one year follow-up, using a U.S. national panel survey of patients in 62 methadone, outpatient, short-term residential, and long-term residential programs. A favorable evaluation of treatment near the time of discharge had a significant positive relationship with drug use improvement outcomes approximately one year later, independent of the separately measured effects of treatment duration, counseling intensity, patient adherence to treatment protocols, pre-treatment drug use patterns, and other characteristics of patients and treatment programs.
