Abstract Background To tailor physical activity treatment programs for patients with osteoarthritis, clinicians need valid and feasible measurement tools to evaluate habitual activity. The widely used International Physical Activity Questionnaire-Short Form (IPAQ-SF) is not previously validated in osteoarthritis. Purpose assess the concurrent criterion validity of IPAQ-SF using an accelerometer as a criterion-method. Method Patients osteoarthritis ( n = 115) were recruited at Division Rheumatology Research Diakonhjemmet Hospital (Oslo, Norway). was measured by wearing (ActiGraph wGT3X-BT) seven consecutive days, followed reporting their past 7 days IPAQ-SF. Comparison proportions that fulfilled recommendations two methods tested Pearson Chi-Square analysis. Differences levels between analyzed Wilcoxon Signed-Rank Test Spearman rank correlation test. Bland-Altman plots visualize total- intensity-specific levels. Results In total, 93 provided complete data, mean (SD) age 65 (8.7) years, 87% women. According IPAQ-SF, 57% minimum compared 31% according p 0.043). When comparing we found significant under-reporting total MET-minutes (p < 0.001), sitting 0.001) walking over-reporting moderate-to-vigorous 0.001). For different levels, correlations ranged from rho 0.106 0.462. indicated increased divergence increasing time spent on intensity Conclusion core Our finding tend over-report higher under-report low-intensity sitting-time clinical importance. We conclude weak
