Introduction: Road traffic crashes are responsible for 1.35 million fatalities worldwide annually. Male drivers and driving while impaired (DWI) offenders are at heightened risk for engaging in risky driving. Males with a depressed mood are also more prone to alcohol misuse, which may further contribute to risky driving. This study investigates the predictive potential of a combination of depressed mood and alcohol misuse on risky driving outcomes 3 and 9 years after baseline in male DWI offenders. Methods: Participants were invited to complete self-report questionnaires assessing depressed mood (Major Depression scores on the Millon Clinical Multiaxial Inventory-III; MD), alcohol misuse (Alcohol Use Disorders Identification Test; AUDIT), and risky driving (Analyse des comportements routiers; ACR). The ACR was repeated at annual follow-up visits for 3 years. Driving conviction data were obtained from the Société de l'assurance automobile du Québec for 9 years after baseline. Data were analysed using hierarchical regressions. Results: As 50.4% of the sample (n=129) were missing data on ACR3 scores, multiple imputation was conducted. In the final regression model (F=8.76, df=7, p<.001), AUDIT scores were a significant predictor of ACR3 (β=0.56, t=1.96, p=.05). MD scores, however, did not significantly predictor ACR3. Neither AUDIT nor MD scores were significant predictors of risky driving convictions 9 years later. Discussion: These findings identify alcohol misuse as a predictor of risky driving 3 years after baseline among male DWI offenders. This enhances our prediction of risky driving, extending beyond the widely researched acute impacts of alcohol by exploring chronic patterns.
