目的：探讨妇女健康倡议（WHI）中体力活动（PA）测量的心理测量特征。方法：参加女性健康饮食与生活研究的确诊乳腺癌女性（平均年龄55岁）佩戴加速度计1周，完成7天体力活动回忆（PAR）和简短的WHI测量。结果：两种自我报告与加速度计的相关性为0.73，对满足当前PA指南的敏感性为100%，但对PAR的特异性明显更高。结论：与广泛接受的PAR相比，WHI测量具有相当的效度、敏感性和测量偏差。
Objective: To investigate the psychometric properties of the physical activity (PA) measure of the Women's Health Initiative (WHI). Methods: Women diagnosed with breast cancer and enrolled in the Women's Healthy Eating and Living Study (average age 55 years) wore an accelerometer for 1 week and completed the 7-day Physical Activity Recall (PAR) and brief WHI measure. Results: Both self-reports correlated 0.73 with the accelerometer and had 100% sensitivity for meeting the current PA guideline, but specificity was significantly higher for the PAR. Conclusions: The WHI measure had comparable validity, sensitivity, and measurement bias compared to the widely accepted PAR.
