Assessing DUI risk: Examination of the Behaviors & Attitudes Drinking & Driving Scale (BADDS)

Despite research findings indicating attitudinal differences among drivers with and without a history of driving under the influence (DUI) offenses, there are no well-established instruments specifically designed to clinically assess drinking and driving attitudes and behaviors among adults. The purpose of this current series of three studies was to investigate the psychometric properties of the Behaviors & Attitudes Drinking & Driving Scale (BADDS). The BADDS was developed in previous studies by the authors and assesses respondents' rationalizations for drinking and driving, likelihood of future drinking and driving, drinking and driving behaviors, and riding with a drinking driver behavior in the previous month. Study 1 (N = 179) and Study 2 (N = 338) assessed college participants, while Study 3 gathered data from adult DUI offenders (N = 160) and non-DUI offenders (N = 166). Results indicate good to excellent test–retest reliability and internal consistency estimates for BADDS scale scores. Support for the construct validity as well as concurrent and predictive criterion validity of BADDS scores was also demonstrated. Potential applications for the measure, as well as need for future research are described.
