The sample used in this study consists of visitors (age range 16-25 years) of 14 disco's in the Dutch province of Groningen. Before entering the disco, they were asked to cooperate in a questionnaire study. Of the 751 persons who were willing to cooperate, 75.3% (N=556) actually returned the questionnaire. Unsafe drinking and driving behaviour was operationalised as drinking more than 2 glasses of alcoholic beverages. The prevalence of unsafe drinking and driving behaviour for the last two disco visits was 21.8%. Driving a bicycle after drinking more than two glasses was by far the most prevalent form of unsafe driving (20%). Driving a car after drinking more than two glasses (0.6%) or driving with someone else who had drunk morethan two glasses was far less prevalent. Logistic regression was used to determine which factors correlate most strongly with driving a bicycle after drinking more than two glasses. Self efficacy, attitudes and norms about alcohol consumption, frequency of visiting public drinking places, and aless strict norm about alcohol consumption and bicycling appear to be the best predictors.
