背景资料：对老年人身体活动干预措施的有效评估需要具有可接受的心理测量特性的测量工具，这些测量工具具有足够的灵敏度来检测该人群的变化。（信度和效度）的社区健康活动模式计划的老年人（CHAMPS）问卷在老年澳大利亚人的样本。CHAMPS数据收集自167名老年人（平均年龄79.1 S.D. 6.3年），并验证了体能测试和SF-12的身体和心理健康的措施。从一个子样本的43名老年人的反应被用来评估1周的重测reliability.Results：大约25%的参与者需要协助完成CHAMPS问卷。CHAMPS评分与身体机能指标（rho=0.14-0.32）和SF-12的身体健康量表（rho=0.12-0.24）之间存在低但显著的相关性。中等强度体力活动的信度系数最高（ICC=0.81-0.88），高强度体力活动的信度系数最低（ICC=0.34-0.45）。对健康有益的足够体力活动的重测估计值之间的一致性（>= 150分钟，每周>= 5次）（一致性百分比= 88%，Cohen's kappa = 0.68）。这些研究结果表明，CHAMPS问卷具有可接受的测量特性，因此适合在澳大利亚老年人中使用，只要在管理期间提供足够的帮助。(c)2006年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Background: The effective evaluation of physical activity interventions for older adults requires measurement instruments with acceptable psychometric properties that are sufficiently sensitive to detect changes in this population.Aim: To assess the measurement properties (reliability and validity) of the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire in a sample of older Australians.Methods: CHAMPS data were collected from 167 older adults (mean age 79.1 S.D. 6.3 years) and validated with tests of physical ability and the SF-12 measures of physical and mental health. Responses from a sub-sample of 43 older adults were used to assess 1-week test-retest reliability.Results: Approximately 25% of participants needed assistance to complete the CHAMPS questionnaire. There were low but significant correlations between the CHAMPS scores and the physical performance measures (rho=0.14-0.32) and the physical health scale of the SF-12 (rho=0.12-0.24). Reliability coefficients were highest for moderate-intensity (ICC=0.81-0.88) and lowest for vigorous-intensity physical activity (ICC=0.34-0.45). Agreement between test-retest estimates of sufficient physical activity for health benefits (>= 150 min and >= 5 sessions per week) was high (percent agreement = 88% and Cohen's kappa = 0.68).Conclusion: These findings suggest that the CHAMPS questionnaire has acceptable measurement properties, and is therefore suitable for use among older Australian adults, as long as adequate assistance is provided during administration.
