Validation study reveals acceptable criterion validity but overreported physical activity in adults, highlighting low sensitivity for tracking guideline adherence.
Our results indicate that the short, last 7-days version of the IPAQ has acceptable criterion validity for use in Swedish adults. However, the IPAQ instrument significantly overestimated self-reported time spent in PA. The specificity to correctly classify people achieving current PA guidelines was acceptable, whereas the sensitivity was low.
