Study Details

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.
