中华生存质量量表对慢性心力衰竭患者的心理测量学评价

Psychometric Properties of the Chinese Quality of Life Instrument in Patients with Chronic Heart Failure

目的探讨中华生存质量量表对慢性心力衰竭患者生存质量评价中的信度、效度和反应度。方法采用中华生存质量量表、世界卫生组织生存质量测定简表中文版(WHOQOL-BREF)、健康状况调查问卷中文版(SF-36)及明尼苏达州心力衰竭生活质量问卷中文版(MLHF)同时对39例慢性心力衰竭患者的生存质量进行评价和随诊观察。结果中华生存质量量表具有较好的内部一致性(Cronbach’sα均>0·7);因子分析产生的3个因子与量表的理论结构模型一致;同时此量表与WHOQOL-BREF、SF-36和MLHF相比,具有较好的效标效度;4周后共有32例完成随访,根据患者的自我病情评价和医生对患者治疗前后心功能的评价,发现中华生存质量量表的反应度明显优于同样是普适性量表的WHOQOL-BREF和SF-36,略逊于特异性量表MLHF。结论中华生存质量量表用于心力衰竭患者生存质量评价时具有较好的信度、效度和反应度。

Objective To assess the reliability, validity and responsiveness of the Chinese Quality of Life Instrument （ChQOL） in patients with chronic heart failure （CHF）. Methods Assessment on quality of life （QOL） of 39 CHF patients was performed in synchronous step adopting three generally used questionnaires the World Health Organization Quality of Life Assessment （WHOQOL-BREF）, the Medical Outcomes Study Short Form 36-items Health Survey （SF-36）, and the Minnesota Living with Heart Failure Questionnaire （MLHF）, as well as the ChQOL respectively. Results ChQOL showed good internal consistency （Cronbach＇s α 〉0.7）, with its theoretical structural model consistent with the three factors produced from factor analysis, and showed better criterion validity than that of WHOQOL-BREF, SF-36 and MLHF. The 4 weeks＇ follow-up visiting completed in 32 patients showed that according to patients＇ self-evaluation and the cardiac functional assessment by the doctors, the responsiveness of the ChQOL was better than that of the WHOQOL-BREF and SF-36, but slightly inferior to that of the MLHF. Conclusion ChQOL showed good reliability, validity and responsiveness in assessing QOL of CHF patients.
