本研究检验了多发性硬化症患者体力活动测量分数的有效性。参与者（N = 196）完成了2项身体活动的自我报告测量，并佩戴了计步器和加速计7天。客观器械评分之间存在较大相关性（r = 0.82），自我报告调查评分之间存在中度相关性（r = 0.37）。测量方法之间的相关性在量级上是中等到大的（r = 0.32-0-53的范围）。我们的研究结果为多发性硬化症患者体力活动评分的有效性提供了更有力、更令人信服的依据。
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.
