该研究的目的是评估两种适合五年级儿童流行病学研究的身体活动回忆工具。这些工具是相似的，除了一个（PACI）是在个人访谈中使用的，另一个（SAPAC）是在小组环境中自我完成的。两种表格都要求孩子们报告前一天他们在 21 种常见体育活动中所花费的时间，这些体育活动代表了一系列强度，以及久坐的活动。为了验证回忆，孩子们在采访前一天同时佩戴加速计（运动传感器）和心率监测器至少 8 小时。受试者包括来自美国四个地区的 55 名男孩和 70 名女孩。自填表和访谈员填表之间的 Pearson 相关性为 0.76（P < 0.001）。访谈者填写的表格与心率指数的相关性为 0.51 (P < 0.001)，与加速度计得分的相关性为 0.33 (P < 0.001)。自我管理形式与心率指数的相关性为 0.57 (P < 0.001)，与加速度计得分的相关性为 0.30 (P < 0.001)。结论是，这两种自我报告表的有效性在所有性别和种族亚群体中都得到了适度的支持。自管理格式更具成本效益。
The purpose of the study was to evaluate two physical activity recall instruments appropriate for use in epidemiologic studies of fifth grade children. The instruments were similar, except one (PACI) was administered in a personal interview, and the other (SAPAC) was self-completed in a group setting. Both forms required children to report the minutes during the previous day they spent in 21 common physical activities that represented a range of intensities, plus sedentary pursuits. To validate the recalls, children simultaneously wore an accelerometer (motion sensor) and a heart rate monitor for at least 8 h the day before the interview. Subjects were 55 boys and 70 girls from four regions of the United States. The Pearson correlation between the self- and interviewer-administered forms was 0.76 (P < 0.001). The interviewer-administered form correlated 0.51 (P < 0.001) with the heart rate index and 0.33 (P < 0.001) with the accelerometer score. The self-administered form correlated 0.57 (P < 0.001) with the heart rate index and 0.30, (P < 0.001) with the accelerometer score. It is concluded that both self-report forms received moderate support for their validity in all gender and ethnic subgroups. The self-administered format is more cost-effective.
