The purpose of this project was to clarify the methodological considerations involved in the posttreatment follow-up evaluation of alcohol-abuse patients. A two-part project was undertaken in an attempt to answer the follow-up questions of how and when to measure treatment effects with discharged alcoholics. In Part I, a large-scale survey was utilized to examine return rates across various program evaluation methods and time frames. In Part II, the predictive validity of scores received at short-term follow-up in relation to scores received at 1-year follow-up was assessed for measures of psychosocial functioning and alcohol consumption.
