Trial Outcomes & Findings for Reinforcement of Abstinence and Continuing Care in Substance Abuse Treatment (NCT NCT00288886)

NCT ID: NCT00288886

Last Updated: 2015-04-24

Results Overview

Participants who were abstinent was assessed via Form-90 Interview (Form 90I) is a structured interview that assesses substance use and related behaviors over the previous 90 days employing a calendar-based follow-back method that provides continuous measures of substance use, and has good reliability. Measures include days abstinent, days using alcohol, days using drugs, total number of standard drinks, and days of self help meeting attendance. Briefer versions were constructed to collect data via telephone in instances when participants did not return for in-person interviews. As a reliability check on participants' self-report, a collateral interview was employed when contacting informants. Participants who denied use on the Form-90, but had a positive substance use screen were considered to be not abstinent for that follow-up point.

Measure
Standard Treatment (STX)
Control condition: Routine residential treatment and orientation to continuing care. An addiction therapist from the participants' treatment program met with each participant for an individual aftercare orientation session during the final 4 days of the initial treatment program and again during the ninth week of aftercare. Individuals were also encouraged to get an AA or NA sponsor during this session.
Contracts, Prompts and Reinforcement (CPR)
Contracting, Prompting \& Reinforcing Abstinence \& Attendance: Contingent reinforcement of abstinence and prompting of AA/NA attendance CPR participants received the STX aftercare orientation except they were also provided with the contracting intervention during the orientation sessions, as well as the prompting and reinforcement components of the intervention. * Contracting. Participant's completed a behavioral contract for continuing care participation that took approximately 20 minutes to complete during their final 4 days in initial treatment and after 9 weeks of participation in continuing care. * Prompting. CPR participants received prompts (mailed appointment cards, telephone reminders) to attend all of their aftercare appointments and AA/NA meetings, and following missed aftercare sessions for 1 year (or until discharged from treatment). * Reinforcement. CPR participants received social reinforcement (certificates, honor roll) for attending group therapy.
