    Background: The International Physical Activity Questionnaire-Short Form (IPAQ-S) has been evaluated against accelerometer-determined physical activity measures in small homogenous samples of adults in the United States. There is limited information about the validity of the IPAQ-S in diverse US samples. Methods: 142 Blacks residing in low-income housing completed the IPAQ-S and wore an accelerometer for up to 6 days. Both 1 - and. 10-minute accelerometer bouts were used, to define time spent in light, moderate, and vigorous physical activity. Results: We found fair agreement between the IPAQ-S and accelerometer-determined physical activity (r = .26 for 10-minute bout, r = .36 for 1-minute bout). Correlations were higher among men than women. When we classified participants as meeting physical activity recommendations, agreement was low (kappa = .04, 10-minute; kappa = .21, 1-minute); only 25% of individuals were classified the same by both instruments (10-minute bout). Conclusions: In one of the few studies to assess the validity of a self-reported physical activity measure among Blacks, we found moderate correlations with accelerometer data, though correlations were weaker for women. Correlations were smaller when IPAQ-S data were compared using a 10- versus a 1-minute bout definition. There was limited evidence for agreement between the instruments when classifying participants as meeting physical activity recommendations. © 2008 Human Kinetics, Inc.
