Computerized Health Education to Promote Physical Activity

Study Overview
=================
Brief Summary
-----------------
This study will test the efficacy of providing primary care physicians and their patients with computer-tailored information, based on patients' responses to survey questions. The health education messages are designed to encourage patients to become physically active and to encourage physicians to counsel their patients about exercise.

Detailed Description
-----------------
The main objective of this study is to determine, via a 6-month randomized controlled study, the efficacy of providing tailored physical activity computer reports to patients and physicians. The primary outcome is minutes of physical activity measured by the 7-Day Physical Activity Recall interview at 6 months. The intervention group completed physical activity surveys at baseline, 1, 3, and 6 months. Based on their responses, participants received four feedback reports at each time point. The reports aimed to motivate participants to increase physical activity, personalized to participants' needs; they also included an activity prescription. The control group received identical procedures, except that they received general reports on preventive screening based on their responses to preventive screening questions.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 7-Day Physical Activity Recall (7-Day PAR) | Minutes of physical activity measured by the 7-Day Physical Activity Recall (7-Day PAR), which is an interviewer-administered self-report physical activity measure of minutes spent in moderate and vigorous intensity leisure and non-leisure activities over the preceding 7 days. It was administered to study participants at baseline and 6 months. | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Behavioral Processes of Change Between Baseline and 6 Months | Behavioral processes were assessed by asking participants to rate their responses to 24 statements on a Likert scale (1 = never to 5 = repeatedly) to statements such as, I tell myself I am able to be physically active if I want to. To create the overall measure, individual items are averaged. Higher numbers represent greater use of behavioral processes of change, so that the overall scale retains a maximum of 5.0 and minimum value of 1.0. The scale values are not numerical, they represent scores on the scale, where 5=repeatedly and 1=never. | Baseline and 6 months |
