目的：有效地评估干预措施，以增加老年人的身体活动。需要可靠和有效的身体活动测量，其还可以检测该人群中身体活动变化的预期类型。本文描述了一个自我报告的身体活动问卷的老年男性和女性，开发的社区健康活动模式计划老年人（CHAMPS），干预措施，以增加身体活动的结果进行评估。方法：问卷评估了老年人通常进行的各种体育活动的每周频率和持续时间。我们估计了体力活动消耗的卡路里/周，并创建了一个汇总频率/周测量。我们计算了以下各项的测量值：1）至少中等强度的活动（MET值大于或等于3.0）; 2）所有指定的身体活动，包括轻度活动。对不太可能发生变化的参与者（仅评估对照组）进行了6个月的稳定性评估。体力活动组）。进行了几项结构效度测试，并根据对CHAMPS干预的反应分析了对变化的敏感性。结果：样本（N = 249）包括活动不足的人（N = 173从CHAMPS试验）和活跃的人（N = 76）。样本年龄为65-90岁（平均值= 74，SD = 6）：64%为女性，9%为少数民族。使用组内相关系数，6个月稳定性范围为0.58 - 0.67。几乎所有的结构效度假设得到证实，虽然相关性是适度的。所有指标对变化敏感（P小于或等于0.01），具有小到中等的效应量（0.38-0.64）。结论：CHAMPS测量可能有助于评估旨在提高老年人身体活动水平的计划的有效性。
Purpose: To evaluate effectively interventions to increase physical activity among older persons. reliable and valid measures of physical activity are required that can also detect the expected types of physical activity changes in this population. This paper describes a self-report physical activity questionnaire for older men and women, developed to evaluate the outcomes of the Community Healthy Activities Model Program for Seniors (CHAMPS), an intervention to increase physical activity. Methods: The questionnaire assesses weekly frequency and duration of various physical activities typically undertaken by older adults. We estimated caloric expenditure/wk expended in physical activity and created a summary frequency/wk measure. We calculated measures of each of these for: 1) activities of at least moderate intensity (MET value greater than or equal to 3.0); and 2) all specified physical activities, including those of light intensity. Six-month stability was estimated on participants not likely to change (assessment-only control group. physically active cohort). Several tests of construct validity were conducted, and sensitivity to change was analyzed based on response to the CHAMPS intervention. Results: The sample (N = 249) comprised underactive persons (N = 173 from the CHAMPS trial) and active persons (N = 76). The sample was aged 65-90 yr(mean = 74, SD = 6): 64% were women, and 9% were minorities. Six-month stability ranged from 0.58 to 0.67, using intraclass correlation coefficients. Nearly all construct validity hypotheses were confirmed, though correlations were modest. All measures were sensitive to change (P less than or equal to 0.01), with small to moderate effect sizes (0.38-0.64). Conclusions: The CHAMPS measure may be useful for evaluating the effectiveness of programs aimed at increasing levels of physical activity in older adults.
