Intoxicated and bad drivers: subgroups within the same population of high-risk men drivers.

Three groups of men drivers in the state of Washington were compared: those who had been arrested for driving while intoxicated (DWI group, N = 172), those who had received multiple nonalcohol-related violations or who had been involved in traffic accidents (high-risk drivers, or HRD group, N = 193) and a representative random sample of the general driving population of men in the state (GDP group, N = 154). Subjects completed a questionnaire assessing demographic, drinking, driving attitude, personality and hostility measures. The HRD and DWI groups were generally more deviant than the GDP subjects. The latter individuals were demographically more stable, had lower levels of drinking behavior and were more emotionally stable, with lower levels of depression, sensation seeking, external perception of control, and both overt and covert hostility. The GDP group also had lower levels of driving-related hostility. The HRD and DWI groups did not suffer significantly from each other on any of the measures of personality function or hostility. These two groups did differ on aspects of drinking behavior, driving-related attitudes and demographic characteristics. The noted similarities between the DWI and HRD groups are consistent with the contention that these two groups may represent subtypes within a larger population of high-risk drivers.
