摘要
目的评价慢性阻塞性肺疾病(COPD)稳定期临床症状测评问卷(测试版)(以下简称"COPD问卷")的信度、效度和反应度。方法选取2008年1月至2010年6月河南中医学院第一附属医院等4家三级甲等医院收治的306例COPD稳定期患者进行问卷调查,以Cronbach'α系数、Guttman分半信度和重测信度评价信度,以敏感性分析、内容效度和结构效度评价问卷效度,以应答率评价可行性,以治疗前后积分配对t检验评价问卷反应度,并评价效应尺度。结果问卷有效应答率95.1%,可行性良好;测评问卷的Cronbach'α系数为0.733、Guttman分半系数为0.817,内在信度较好,重测信度较低,外在信度一般;各条目与总分间的相关系数较好,但各条目间的相关系数较小;公因子分析λ>1时共筛选出2个公因子,结构效度较好;问卷各条目和总分治疗前后t检验差异具有统计学意义(P<0.05),反应度较好;除咯痰条目外,其余条目和总分均为中等或较大效应尺度。结论 COPD问卷在COPD稳定期患者具有较好的信度和结构效度,内容效度一般,能够较好地反映治疗效果,可作为COPD患者的临床疗效评价测评工具。
Objective To evaluate the reliability, validity and reaction degrees of the clinical symptom assessment questionnaire of chronic obstructive pulmonary disease （COPD） at stationary phase （beta）. Methods Since January 2008 to June 20106, 306 inpatients with COPD at stationary phase were chosen from the first affiliated hospital of Henan College of Chinese medicine and other three tertiary referral hospitals to finish the question investigation. The reliability degree was evaluated with Cronbach＇ α factor and Guttman 1/2 reliability and resurvey reliability. The validity degree was assessed with sensitivity analysis, content validity and construct validity. The feasibility was estimated with response rate. And the reaction degree and effect magnitude were evaluated with the integrals before and after treatment paired T test. Results The effective response rate of COPD questionnaire was 95.1%, which shown an excellent feasibility. The Cronbach＇ α factor was 0. 733 and Guttman 1/2 reliability was 0. 817, which presented a good internal reliability, a low resurvey reliability and a fair external reliability. The correlation seemed good between each entry and the total score, while poor among the entries. Two common factors were screened by factor analysis when λ 〉 1 inferred a good construct validity. There were significant differences （ P 〈 0. 05 ） in the T test analysis between each item score and the total scores before and after treatment which was shown a good reaction degree. Effect magnitude of the total scores and scores of each item except item of cough up phlegm presented medium or upper effects. Conclusion The COPD questionnaire presented a good reliability and construct validity, but a general content validity in COPD patients at stationary phase. It could reasonably reflect the treatment effects, so as to be a clinical effect evaluated tool in COPI） patients.
