Study Description
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.

Condition or disease Intervention/treatment Phase
Physical Activity Behavioral: Web-based Motivational Interviewing Phase 1

Detailed Description:
Increasing physical activity (PA) is a public health priority. There is preliminary support for application of Motivational Interviewing (MI) for physical activity (PA), web-applications for PA promotion, web-based MI for behavior change, and finally web-based MI for PA. Based on collective findings in these areas of inquiry, it is necessary to investigate the efficacy of MI as a method that lends readily to practical applications for PA promotion. The current study seeks to investigate whether web-based MI can be applied in an adult population to enhance PA participation using a physician referral scheme. Additionally, mechanisms of behavior change are considered in order to inform future research and intervention.

Arms and Interventions

Arm Intervention/treatment
Experimental: Web-based, Mi=Based Intervention
4 session web-based, MI-based intervention.
Behavioral: Web-based Motivational Interviewing
Participants will engage in 4 sessions of web-based motivational interviewing over the course of 4 weeks.


Outcome Measures

Primary Outcome Measures :
  1. Physical Activity (pedometer recordings) [ Time Frame: 1 week post-intervention ]
    Physical activity will be assessed using pedometers.

  2. Physical activity (self-report) [ Time Frame: 3-months post-intervention ]
    Physical activity will be assessed using a self-report inventory.


Secondary Outcome Measures :
  1. Cognitive Mediators [ Time Frame: 3 months post intervention ]
    Cognitive mediators of physical activity participation including self-efficacy, readiness to change, motivation, intention, enjoyment, and decisional balance for physical activity will be assessed.
