The degree of methodological control in Nathan Azrin's early studies and the surprisingly large treatment effects that were obtained established the Community Reinforcement Approach (CRA) as one of the more promising interventions for alcohol problems. With a larger sample of clients, the authors tested CRA in an ongoing public outpatient treatment program, the University of New Mexico Center on Alcoholism, Substance Abuse, and Addictions (CASAA), the largest public provider of addiction treatment services in New Mexico. A range of outcome measures was included to document drinking, alcohol-related problems and dependence, psychological adjustment, employment, and institutionalization. The authors have replicated Azrin's outpatient study by reproducing the same three treatment conditions: traditional treatment alone, traditional treatment plus disulfiram compliance, and full CRA. To these they added another group, who received CRA without disulfiram, in order to determine the extent to which disulfiram contributes to the overall effectiveness of the CRA.
