This chapter contains the primary report of findings from the comparison of the Community Reinforcement (CRA) and traditional approaches. Study participants completed a comprehensive assessment at intake that included measurement of numerous demographic characteristics, motivation for change, psychological functioning, drinking history, and current drinking practices. The taking and monitoring of disulfiram were important distinguishing aspects of the treatment groups. The a priori treatment contrasts were made at proximal and distal follow-up points using three primary dependent measures. The three outcome measures were total standard drinks consumed during the assessment period, number of drinking days per week, and estimated peak blood alcohol concentration (BAC) for the assessment period. Traditional and CRA groups also had similar outcomes among the disulfiram-ineligible clients. The chapter concludes with a confessional litany of some errors the authors made along the way, in the hope of saving colleagues from similar pitfalls.
