Abstract

Using data from a general-population telephone survey conducted from July 2002 through June 2005 (n=6259), the current study assessed gender as a potential moderator of the relationship between self-reported driver aggression and various demographic variables, general and driving- related risk factors. The initial analysis was a hierarchical-entry regression examining self- reported driver aggression in the last 12 months. All demographic and risk-factor variables were entered in the first block, and all two-way interactions with gender were entered stepwise in the second block. A subsequent analysis divided the sample by gender and conducted logistic regressions with main effects only for males (n=2921) and females (n=3338) separately. Although the prevalence of driver aggression in the current sample was slightly higher among males (38.5%) than females (32.9%), the difference was small, and gender did not enter as a significant predictor of driver aggression in the overall logistic regression. Gender was found to moderate the relationships between driver aggression and only three variables: income, psychological distress, and driving exposure. Separate analyses on the male and female sub- samples also found differences in the predictive value of income and driving exposure; however, the difference for psychological distress could not be detected using this separate regression approach. The secondary analysis also identified slight differences in the predictive value of four of the risk factors, where the odds ratios for both males and females were in the same direction but only one of the two was statistically significant. Thus, with few exceptions, factors that were predictive of driver aggression were generally the same for both male and female drivers.
