Brief Motivational Intervention to Increase Physical Activity and Fruit/Vegetable Intake

Study Overview
=================
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

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Brief Motivational Intervention<br>Subjects in this condition met one-on-one with a counselor for 30 minutes.
