College students' readiness to reduce binge drinking: criterion validity of a brief measure.

We assessed the criterion-related validity of a contemplation ladder used to determine college students' readiness to reduce binge drinking. 1356 students in halls of residence in Dunedin, New Zealand completed a self-report survey including the contemplation ladder, AUDIT questionnaire, and other alcohol-related measures. Two groups of binge drinkers were identified, one reporting bingeing more than twice per week (n=645), and one bingeing 1-2 times per week (n=237). A third group did not report binge drinking (n=474). A higher readiness to change binge drinking was associated with more frequent bingeing, more interpersonal and academic problems with alcohol, less frequent use of cannabis, and living in a hall with a norm of binge drinking. The contemplation ladder for alcohol was sensitive to other alcohol-related behaviours, and may be useful in surveys of drinking where a brief measure of readiness to change is needed.
