Does change talk during brief motivational interventions with young men predict change in alcohol use?

Client change talk (CT) during motivational interviewing and brief motivational interventions (BMIs) have been described as predictors of behavior change, but these links have not been clearly evaluated in research on young people. Within 127 BMIs with 20-year-old men with at-risk alcohol consumption, each CT utterance was categorized and given a strength rating using the Motivational Interviewing Skill Code 2.1. Several ways of categorizing and measuring CT were tested using stepwise regression procedures. Overall CT measures were not significantly related to changes in drinking at 6-month follow-up. Regarding CT sub-dimensions, the frequency of ability/desire/need to change and of ability/desire/need not to change, as well as the average strength of ability/desire/need, predicted significant change in the expected direction. CT length was not significantly linked to outcome. The frequency and strength with which some CT sub-dimensions are expressed during BMI seemed to be important predictors of change in drinking among young men and might thus be especially important for clinicians to notice.
