ABSTRACT Introduction: This study examined the validity of several methods of physical activity assessment in older adults. The physical activity questionnaires (PAQs) used included two designed for use with older adults known as the Yale Physical Activity Survey (YPAS) and the Physical Activity Scale for the Elderly (PASE) and one designed for use in the general population, the 7 Day Physical Activity Recall (PAR). These PAQs along with one accelerometer, the ActiGraph GT1M (GT1M), were examined in comparison to the criterion method, the SenseWear Pro 3 Armband (SP3). Methods: Participants (n = 36; age = 69.7 ± 5.9 years) wore the SP3 and the GT1M for seven days. At the end of the seven days, participants completed the YPAS, PASE, and PAR. Pearson and Spearman correlation coefficients were used to examine significant relationships. Paired samples t-tests and Bland-Altman plots investigated further differences between methods. Results: GT1M’s estimates of daily steps were not significantly correlated (r = .369) with SP3 assessment of daily steps. The ACT-F (r = .620) and ACT-C (r = .524) equations each demonstrated a significant (P
