目的：验证 7 天体力活动回忆 (PAR) 电话访谈版本及其活动强度类别。方法：使用相同的 PAR 协议，对年龄（18-67 岁）和活动水平不等的 74 名成年人（47 名女性、27 名男性）进行了电话和面对面采访。每个参与者佩戴 TriTrac-R3D(R) 加速度计 10 天。通过将电话采访和现场 PAR 采访与 TriTrac-R3D(R) 数据进行比较来评估有效性。结果：69 名成年人（44 名女性，25 名男性）用于所有统计分析。两次 PAR 访谈之间每周活动总分钟数的组内相关性为 r = 0.96，中等程度的 r = 0.94，困难的 r = 0.97。对于非常高强度的活动，r = 0.97。电话 PAR 与每周体力活动总分钟数的 TriTrac-R3D(R) 之间的 Pearson 乘积矩相关性为 r = 0.43，对于中等强度活动，r = 0.31，对于高强度活动，r = 0.39，对于非常高强度活动，r = 0.78。现场 PAR 与每周体力活动总分钟数的 TriTrac-R3D(R) 之间的 Pearson 相关性为 r = 0.41，中等强度活动 r = 0.33，高强度活动 r = 0.43，非常高强度活动 r = 0.74。与 TriTrac-R3D(R) 相比，参与者在两次访谈中高估了体力活动量。结论：电话版本和面对面版本的 PAR 是自我报告身体活动的等效衡量标准。无论年龄、体重指数或体力活动水平如何，两种访谈方法对每周中等、剧烈和非常剧烈活动的总分钟数都有相似的估计。与非常艰苦的活动相比，中等和艰苦的活动中每种访谈方法与 TriTrac-R3D(R) 之间的相关性较低。
Purpose: To validate the 7-d Physical Activity Recall (PAR) telephone interview version and its activity intensity categories. Methods: Seventy-four adults (47 women. 27 men), ranging in age (18-67) and activity levels, were interviewed by phone and in-person using the same PAR protocol. Each participant wore a TriTrac-R3D(R) accelerometer for 10 d. Validity was assessed by comparing the phone and in-person PAR interviews with the TriTrac-R3D(R) data. Results: Sixty-nine adults (44 women, 25 men) were used for all statistical analyses. Intraclass correlations between the two PAR interviews for total minutes per week of activity were r = 0.96, and r = 0.94 for moderate, r = 0.97 for hard. and r = 0.97 for very hard intensity activities. Pearson product moment correlations, between the phone PAR and TriTrac-R3D(R) for total minutes per week of physical activity were r = 0.43, and r = 0.31 for moderate, r = 0.39 for hard, and r = 0.78 for very hard intensity activities. Pearson correlations between the in-person PAR and TriTrac-R3D(R) for total minutes per week of physical activity were r = 0.41, and r = 0.33 for moderate, r = 0.43 for hard, and r = 0.74 for very hard intensity activities. Participants overestimated the amount of physical activity in both interviews as compared with the TriTrac-R3D(R). Conclusion: The phone and in-person versions of the PAR are equivalent measures for self-reported physical activity. Regardless of age, body mass index, or physical activity level both interview methods had similar estimates for total minutes per week of moderate, hard, and very hard activity. Correlations between each interview method and the TriTrac-R3D(R) were lower for moderate and hard activities as compared with very hard activities.
