The Test-Retest Reliability of the Form 90-DWI: An Instrument for Assessing Intoxicated Driving

This article reports on a study that used the Form 90, a widely utilized alcohol and substance use instrument, for measurement of driving while intoxicated (DWI) and related behaviors. The authors tested reliability for the adapted instrument among a university sample of 60 undergraduate students who had consumed alcohol during the past 90 days. The authors administered the instrument once during an intake interview and again, 7-30 days later, to determine levels of test-retest reliability. Overall, the Form 90-DWI demonstrated high levels of reliability for many general drinking and DWI behaviors. However, levels of reliability were lower for riding with an intoxicated driver and for variables involving several behavioral conjunctions, such as seat belt use and the presence of passengers when driving with a blood alcohol concentration above .08. The authors conclude that the Form 90-DWI shows promise as a reliable measure of DWI behavior in research studies on treatment outcome and prevention. This type of instrument is urgently needed, as currently utilized indicators, such as arrests and injuries, occur at low frequency and are influenced by a variety of confounding factors.
