Examining age- and sex-related risk factors in first-time DWI offenders

DWI research has focused on younger males, consequently much less is known about female and older offenders. Quebec data demonstrate a bimodal distribution in first-time driving while impaired (fDWI) offences, a pattern also observed internationally. Males’ fDWI offences peak between the ages of 18 to 25 with a second smaller peak between 35 to 44. In contrast, females' fDWI offences peak between 36 to 47 with a smaller peak between 20 to 27. These observations suggest that the trajectory to fDWI offending is influenced by interactions between sex and age. This preliminary study explores how sex and age may interact to influence the trajectory to fDWI through patterning of alcohol consumption, psychological adjustment, and impulsivity. Individuals arrested for a fDWI within the past two years were recruited. Participants were administered the AUDIT, Timeline Follow Back, MCMI, UPPS, and Stoplight and Balloon Analog Risk Tasks. Thirty-six participants were recruited: younger females, younger males, older males, older females. Younger females engaged in more binge drinking, endorsed greater symptoms of alcohol misuse, and scored higher on urgency than both younger and older males. No significant findings were observed between older females and all other groups. fDWI offending among younger females appear to be related to binge drinking and emotion-related impulsivity. Younger females appear to be different than male offenders of all ages. The findings suggest that female fDWI is not analogous to male fDWI, a postulate that may need to be considered for intervention/prevention efforts with female fDWI offenders.
