Study Details

Study Description

Brief Summary

Research has shown that a high percentage of college students do not meet recommended national guidelines for physical activity or fruit/vegetable intake. The purpose of this study was to pilot test the short-term efficacy of a one-on-one, brief motivational intervention (BMI) designed to increase physical activity and fruit/vegetable intake. It was hypothesized that participants in the BMI condition would report greater physical activity and fruit/vegetable intake at follow-up than those in an education-only control condition.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Brief Motivational Intervention Subjects in this condition met one-on-one with a counselor for 30 minutes. Subjects received personalized feedback regarding their current physical activity levels and fruit/vegetable intake. Counselors used a motivational interviewing style to try to help resolve ambivalence about changing their current behaviors.	Behavioral: Brief Motivational Intervention; 30 minute one-on-one meeting
Active Comparator: Educational information Subjects in this condition received general educational information about the benefits associated with physical activity and fruit/vegetable intake.	Behavioral: Educational information; Educational handouts/brochures
