Abstract This study examined the validity of scores from measures of physical activity among individuals with multiple sclerosis. Participants (N = 196) completed 2 self-report measures of physical activity, and wore a pedometer and an accelerometer for a 7-day period. There was a large correlation between scores from the objective devices (r = 0.82) and a moderate correlation between scores from the self-report surveys (r = 0.37). The correlations across measurement methods were moderate-to-large in magnitude (range of r = 0.32-0.53). Our results provide a stronger and more compelling basis for the validity of scores from measures of physical activity among individuals with multiple sclerosis.
