The effects of protective behavioral strategies on heavy drinking following a pure motivational interviewing...

Protective behavioral strategies (PBS) are cognitive-behavioral strategies that students use to prevent risky drinking. Prior work supports PBS as a mechanism of change following a brief motivational intervention (BMI) among college students. This study investigated the necessity of discussing PBS by examining changes in PBS use and drinking following an alcohol intervention that used the parent method of Motivational Interviewing (MI), or Pure MI.

Data came from a pilot study that looked at the effects of Pure MI that targeted risky social drinking behavior. The study comprised 42 college students who endorsed hazardous drinking in the last 2 weeks and social anxiety symptoms. Participants completed measures of safe and heavy drinking behaviors at baseline and one-month follow-up.

The results showed that PBS use increased from baseline to one-month follow-up. Further, the reduction in heavy drinking in social situations was partially explained by an increase in PBS use from pre- to post-intervention.

Despite not introducing PBS into discussions during the MI intervention, we found that students who used more PBS reported reduced heavy drinking in social situations. Implications from the study suggest that interventions focused on student motivation rather than knowledge can promote safe and reduce hazardous drinking behaviors.
