Abstract

This study assessed the ability of the theory of planned behavior(TPB) to account for drivers' intention and behavior of drinking and driving, comparing other alternative models. A sample of drivers(N=411) was surveyed with questionnaire constructed to measure attitude toward behavior, subjective norms, perceived behavior control, past behavior, habit, obligation, and behavior intention and drunk driving behavior for 1 month. Results showed the addition of past behavior and habit led to the most significant increments(19.5%) in amount of explained variance in intentions and the most significant increments(17%) in drinking and driving behavior, thereby supporting other model instead of TPB. An alternative model was suggested at the based on findings. The limitations of this study and future directions for further study were discussed.
