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.
