Predicting Walking Intentions and Exercise in Individuals With Intermittent Claudication: An Application of the Theory of Planned Behavior

Objective: To identify determinants of intention and walking activity among individuals with intermittent claudication using the theory of planned behavior. Study Design and Participants: Prospective, correlational study of men and women (n = 62) with intermittent claudication. Method: Baseline questionnaire assessing theory of planned behavior measures regarding walking. Telephone follow-up assessing frequency and duration of walking during the previous week. Results: Attitudes, subjective norms, and perceived behavioral control explained 67% of the variance in intentions. Perceived behavioral control explained 8% of the variance in walking activity. Conclusion: Findings support the theory of planned behavior for predicting intentions and warrant future examination of perceived behavioral control as a determinant of exercise. A basis for developing interventions to facilitate walking among this population is provided.
