Abstract: Objective　To develop a family management evaluation questionnaire for patients with chronic obstructive pulmonary disease（COPD） and test its reliability and validity.Methods　Based on the framework of knowledge-attitude-practice theory，the evaluation questionnaire of family management for COPD patients was prepared through literature review，expert consultations and other methods.A total of 245 COPD patients admitted to the outpatient clinics and respiratory wards in four tertiary Level A general hospitals of Tianjin from December 2016 to April 2017 were sampled for a questionnaire survey by convenience sampling method，and 10 days later，30 subjects among them were randomly selected for reliability retest.Content validity index （CVI），exploratory factor analysis，Pearson correlation coefficient，Cronbach's α coefficient and test-retest reliability coefficient were used to screen items and evaluate the reliability and validity of the questionnaire.Results　The final questionnaire consists of 3 dimensions （COPD family management knowledge，family management behavior，and family management attitude） and 44 items.The content validity index of each item （I-CVI） in the questionnaire reached 0.930 or more，and CVI of the questionnaire was 0.997；exploratory factor analysis was used to extract 3 common factors explained 60.143% of the total variance；the total Cronbach's α coefficient of the questionnaire was 0.959，and the test-retest coefficient was 0.938；the Cronbach's α coefficient of 3 dimensions was 0.943-0.953，and test-retest reliability 0.814-0.968.Conclusion　The family management evaluation questionnaire for COPD patients was proved to be reliable and valid.It can be used as a suitable tool to evaluate the level of family management in COPD patients.

摘要： 目的　编制慢性阻塞性肺疾病（COPD）患者家庭管理评估问卷，并进行信效度检验。方法　以知信行理论作为理论框架，通过回顾文献、专家咨询等方法编制COPD患者家庭管理评估问卷。于2016年12月—2017年4月，采用便利抽样的方法，选取天津市4所三级甲等综合医院门诊就诊和呼吸科病房住院的245例COPD患者的主要家庭照护者为调查对象进行问卷调查，10 d后随机抽取其中的30例进行信度重测。基于内容效度指数（CVI）、探索性因子分析、相关性分析、Cronbach's α系数及重测信度等进行问卷条目筛选及信效度检验。结果　最终确定的问卷包括COPD家庭管理知识、家庭管理行为、家庭管理态度3个维度，共44个条目。问卷CVI为0.997，条目水平的内容效度指数（I-CVI）均≥0.930；通过探索性因子分析提取3个公因子，累积方差贡献率为60.143%；问卷总的Cronbach's α系数为0.959，重测信度为0.938；3个维度的Cronbach's α系数为0.943~0.953，重测信度为0.814~0.968。结论　COPD患者家庭管理评估问卷具有良好的信效度，可作为评估COPD患者家庭管理水平的适用工具。
