Previous research from multiple investigators has demonstrated the efficacy of Contingency Management (CM) interventions for reducing substance use and increasing treatment attendance and retention. However, only one small study with alcohol dependent veterans has demonstrated the effectiveness of CM interventions in the VA patient population. This trial of a CM intervention assessed the impact of CM on alcohol and stimulant dependent veterans during the intervention and 6 and 12 months after the intervention.
Investigate the impact of adding a CM intervention to existing VA treatment for drug and alcohol dependence on during-treatment and post-treatment patient outcomes
This was a randomized, controlled trial. Participants included 330 veterans presenting for specialty SUD treatment at the VAMCs in Minneapolis or Seattle with intake diagnoses of alcohol and/or stimulant dependence. Participants were assigned to 8-weeks of Usual Care or Usual Care plus CM and scheduled to meet with a research assistant twice/week to submit urine and breath samples. Participants randomized to CM drew tokens each time they submitted negative urine and breath screens. Tokens earned social reinforcement (Good Job!) or VA canteen vouchers of varying value ($1, $20, or $80). Follow-up assessments occurred 2, 6 and 12 months after enrollment into the study. Primary outcomes included number of days with negative urine drug and breath alcohol screens during the intervention phase, consecutive weeks of treatment attendance during the intervention phase, and self-reported percent days abstinent from alcohol and stimulants on the Timeline Follow-Back interview at follow-up assessments.
Participants randomly assigned to CM attended significantly more intervention appointments and submitted significantly more negative breath and urine screens than participants assigned to Usual Care. Consecutive weeks of usual care treatment attendance did not differ reliably between groups. Follow-up assessment rates did not differ significantly by condition and were obtained for 81%, 76% and 74% of participants at 2-, 6- and 12-months, respectively. At 2-month follow-up, both the Usual Care and the CM participants demonstrated significant improvement in percent days abstinent and these improvements were sustained at the 6- and 12-month follow-ups based on analyses with generalized estimating equations. At 2 months and 12 months, there were no significant between group differences. At 6 months, CM participants reported significantly more abstinent days out of the past 30 (95%) compared to Usual Care (88%). Service utilization data collected over the 12 months of study participation indicated no significant differences between CM and Usual Care in the number of SUD, mental health, and social work outpatient appointments, the number of Emergency Room visits, the number of inpatient mental health hospitalizations, or the number of days hospitalized for mental health issues.
The CM intervention increased appointment attendance during treatment and modestly improved percent days abstinent at 6-month follow-up.
