Abstract

Objective: The objective was to validate self-reported physical activity based on a daily activity record (DAR) with concurrent pedometer and 7-day physical activity-recall questionnaire data. Design: The design was a one-group descriptive correlational study. Sample: The sample consisted of 25 working women with a mean age of 39.8 years, 92% Caucasian, and 63% with a combined family income of $60,000 or greater. Measurements: Three instruments: (a) DAR, a self-reported record of moderate or higher intensity physical activities including household, exercise, leisure, and occupational. Metabolic equivalent unit (MET) scores were calculated from the self-report data, (b) 7-day physical activity recall, and (3) Yamax pedometers (SW-701) measured number of steps. Results: MET scores based on the DAR (n = 22) were strongly associated with both pedometer data (Spearman's rho = 0.607, p = 0.003) and 7-day physical activity-recall data (Spearman's rho = 0.542, p = 0.009). Conclusion: The results of this validation study indicated a statistically significant correlation of self-reported physical activity (DAR) with pedometer values and 7-day physical activity-recall data. The DAR may be useful for measuring physical activity in community health programs and in community-based research.
