【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λ1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(P0.05),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。
[Abstract]:Objective to evaluate the reliability, validity and response of (COPD) stable clinical symptom questionnaire (COPD questionnaire). Methods from January 2008 to June 2010, 306 patients with stable COPD were investigated in 4 Grade 3A hospitals, including the first affiliated Hospital of Henan College of traditional Chinese Medicine, and the reliability was evaluated with Cronbach's 伪 coefficient (Cronbach's 伪 coefficient). The validity of the questionnaire was evaluated by sensitivity analysis, content validity and structural validity, the feasibility was evaluated by the response rate, the response degree was evaluated by the integral paired t test before and after treatment, and the effect scale was evaluated. Results the effective response rate of the questionnaire was 95.1, the Cronbach's 伪 coefficient was 0.733Guttman 's split-half coefficient was 0.817, the internal reliability was better, the test-retest reliability was lower, the external reliability was general, the correlation coefficient between each item and the total score was better. But the correlation coefficient of each item was small; the common factor analysis 位 1 screened out two common factors, the structure validity was better; the difference of t test between the items and total score of questionnaire before and after treatment had statistical significance (P0.05), the reaction degree was better; except for the sputum item, The other items and total scores were medium or large effect scales. Conclusion COPD questionnaire has good reliability, structural validity and general content validity in patients with COPD at stable stage. It can reflect the therapeutic effect well and can be used as a tool for evaluating the clinical efficacy of COPD patients.
