Exercise as an intervention for sedentary hazardous drinking college students: A pilot study.

Area of Science:

• Behavioral Science
• Addiction Medicine
• Public Health

Background:

• Young adults (18-24) exhibit high rates of alcohol-related problems.
• Substance use often correlates inversely with engagement in substance-free activities.
• Exercise is a key substance-free activity with potential to mitigate alcohol misuse.

Purpose of the Study:

• To pilot test the efficacy of motivational enhancement therapy (MET) and contingency management (CM) in promoting exercise among college students with hazardous drinking.
• To assess the impact of MET alone versus MET+CM on exercise participation and alcohol use.
• To inform future, larger-scale trials on exercise interventions for alcohol use reduction.

Main Methods:

• A pilot study randomized 31 sedentary college students with hazardous drinking (AUDIT scores ≥ 8) into two groups.
• Group 1 received one session of MET focused on increasing exercise.
• Group 2 received MET plus 8 weeks of CM for exercise adherence; both groups evaluated at baseline and 2-month follow-up.

Main Results:

• Both interventions were well-received by participants.
• The MET+CM group reported a higher frequency of exercise compared to the MET-alone group.
• No significant differences were observed between groups in other exercise indices, physical fitness, or alcohol use over time.

Conclusions:

• The MET+CM intervention shows promise for increasing exercise frequency in college students with hazardous drinking.
• Further research with larger sample sizes is warranted to confirm the efficacy of this combined intervention.
• Exploring this intervention in other populations at risk for alcohol use problems is recommended.
