As the extent of excessive alcohol consumption among college students has gained notoriety in recent years, those negative consequences associated with drinking are currently under investigation. Impaired driving is at the forefront of these alcohol-related problems as a major health concern for universities. The Impaired Driving Assessment (IDA) was developed in order to collect more detailed information about drinking and driving, including such variables as alcohol consumption and BAC during impaired driving episodes. The Transtheoretical Model of Change (TTM) is based on the premise that when people change, they do so through a series of stages (DiClemente & Prochaska, 1982). Past research has shown the TTM to be effective in promoting change when applied to a wide variety of health behaviors. The purpose of this study is to examine the relationship between recent impaired driving behaviors and current readiness to stop drinking and driving in a college student sample. The IDA was administered to 91 college students who reported that they drove after drinking at least twice during the previous month. A total of 38 (41.8%) students indicated that they were not thinking about stopping their drinking and driving, while 53 (58.2%) students reported that they were thinking about stopping their drinking and driving in the future. Analyses revealed a significantly (p < .01) greater number of drinking and driving episodes in the last 5 weeks among those students who were not intending to stop drinking and driving (x=11.1, SD=9.5) than among those students who were intending to stop this current behavior (x=5.8, SD=5.0). The IDA also obtained information on episodes in which the student was a passenger in a car of a driver who had been drinking. However, an individual’s intention to stop drinking and driving did not have an effect on this variable. Among female participants, results indicated those who had no intention of stopping reported significantly (p < .01) more days on which they consumed alcohol (x=10.4, SD=6.4) than those who did intend to stop drinking and driving (x=5.7, SD=3.4). These findings indicate the need for theory-driven interventions to reduce impaired driving behaviors in this population. By incorporating personalized feedback and tailoring the intervention to each individual’s current stage of change, the IDA could serve as a useful component to a program to reduce drinking and driving among college students.Keyword(s): college level issues, health promotion, measurement/evaluation
