An Evaluation of Self-report Physical Activity Instruments Used in Studies Involving Cardiac Patients

Abstract

PURPOSE: Given the importance of physical activity (PA) in cardiac rehabilitation and prevention, measuring it in a valid and reliable manner is a practical challenge. Measuring self-reported PA in elderly cardiac patients can be problematic because of the need to assess many activities of short duration that may occur as part of routine daily functions. The primary purpose of this article was to identify and evaluate instruments that have been used over the last 15 years in studies of cardiac patients. METHODS: A comprehensive MEDLINE search was carried out to identify articles from studies undertaken to assess PA in cardiac patients. The self-report PA instruments were subjected to evaluat..
