Brief Summary
The specific aims of the proposed study are:
- 1\. To determine if web-based Motivational Interviewing (MI) is effective, compared to an informational web-based comparison group, in enhancing physical activity (PA) participation; and
- 2\. To assess the mechanisms by which web-based MI enhances PA through changes in targeted cognitive mediators. The specific hypotheses of the study include that:
- Hypothesis 1: Web-based MI will increase PA;
- Hypothesis 2: Web-based MI will lead to stage progression in the direction of increased readiness to participate in PA;
- Hypothesis 3: Web-based MI will influence theoretically identified cognitive variables;
- Hypothesis 4: Cognitive variables will mediate increases in PA participation.
