Measures of (a) self-efficacy and (b) motivation to change (stage) for controlling drinking and drinking/driving were examined at the beginning and the end of a four-week intervention in a sample of 670 Driving Under the Influence (DUI) offenders in a court-mandated program. Hypotheses regarding stability of stage classifications over the course of intervention, and the relation between stage classification, stage scores, self-efficacy, and DUI recidivism were examined. Based on results of an earlier study it was expected that most offenders would be classified into the action stage at entry and that classification would tend to remain stable from pretest to posttest. Action was the most frequent stage classification in both drinking and drinking/driving domains at both test periods, with precontemplation being the least frequent classification. When tracked over the four weeks, stage classifications for drinking and drinking/driving were stable for 74 to 89% of offenders in the two domains, respectively. As predicted, higher action and self-efficacy scores were related to lower recidivism, and action scores in drinking/driving domain were the best early recidivism predictors among a predictor set that included traditional recidivism indicators. Drinking comtemplators (i.e., those with the highest stage score on the contemplation scale) had higher recidivism rates than other drinking stage classifications. Implications for DUI intervention programs are discussed. (Author/publisher)
