摘要

身体活动是降低慢性阻塞性肺疾病(COPD)患者发病率和死亡率的重要健康行为。准确测量身体活动的特征对于了解慢性阻塞性肺病对身体活动的影响至关重要。在之前的一篇文章中,我们报道了社区健康活动模式计划(CHAMPS)问卷的跨文化适应性,以制作加拿大法语版本。CHAMPS产生四个总结分数:两个热量消耗分数(中等强度活动和所有活动)和两个频率分数(中等强度活动和所有活动)。本研究的目的是评估英文和法文CHAMPS在COPD患者中的重测信度和收敛结构效度。测试-重测信度通过两次访问(间隔2-3周)对19名英语和18名法语参与者进行CHAMPS评估。56名说英语的参与者和74名说法语的参与者在一次访问中完成了CHAMPS,简短表格- (SF-) 36和圣乔治呼吸问卷(SGRQ),对有效性进行了评估。信度检验结果表明,类内相关系数(ICCs)总体上满足良好的信度阈值(ICC > 0.6),频率评分比热量消耗评分表现出更大的稳定性。效度检验显示,CHAMPS与SF-36结构域和身体功能的总结得分,以及与SGRQ活动结构域和总分具有中等相关性(r = 0.4-0.5)。中等强度活动的CHAMPS频率得分与SF-36和SGRQ的身体方面的相关性比其他得分更强。英语和法语版本的CHAMPS在信度(频率得分)或效度(频率和热量消耗得分)上没有显示出任何实质性的差异。本研究的结果支持CHAMPS的信度和效度。特别是,中等强度活动的频率评分可以提供关于慢性阻塞性肺病患者身体活动水平的有用信息。本试验注册号为NCT00169897。ISRCTN注册号:IRSCTN32824512。

Psychometric Testing of the CHAMPS Questionnaire in French Canadians with COPD
Physical activity is an important health behaviour in reducing morbidity and mortality in individuals with chronic obstructive pulmonary disease (COPD). Accurate measurement of the characteristics of physical activity is essential to understanding the impact of COPD on physical activity. In a previous article, we reported on the cross-cultural adaptation of the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire to produce a Canadian French version. The CHAMPS yields four summary scores: two caloric expenditure scores (moderate-intensity activities and all activities) and two frequency scores (moderate-intensity activities and all activities). The objective of this study was to evaluate test-retest reliability and convergent construct validity, in both English and French versions of the CHAMPS, in individuals with COPD. Test-retest reliability was assessed by administering the CHAMPS at two visits (2-3 weeks apart), to 19 English-speaking and 18 French-speaking participants. Validity was assessed in 56 English-speaking and 74 French-speaking participants, who completed the CHAMPS, Short Form- (SF-) 36, and St. George's Respiratory Questionnaire (SGRQ) at a single visit. Results from reliability testing indicated that intraclass correlation coefficients (ICCs) generally met the threshold for good reliability (ICC > 0.6), with frequency scores showing greater stability than caloric expenditure scores. Validity testing yielded moderate correlations (r = 0.4-0.5) of the CHAMPS with the SF-36 domains and summary score capturing constructs of physical function, and with the SGRQ activity domain and total score. CHAMPS frequency scores for moderate-intensity activities correlated more strongly than other scores, with physical aspects of the SF-36 and SGRQ. The English and French versions of the CHAMPS did not show any substantial differences in reliability (frequency scores) or validity (frequency and caloric expenditure scores). Findings from this study support the reliability and validity of the CHAMPS. In particular, frequency scores for moderate-intensity activities can provide useful information on physical activity levels in individuals with COPD. This trial is registered with NCT00169897. ISRCTN registration number: IRSCTN32824512.
