与糖尿病饮食相关的生活质量量表的信效度研究

Evaluation of reliability and validity of Diabetes Diet-Related Quality-of-Life Scale

目的评价中文版与糖尿病饮食相关的生活质量（ Diabetes Diet- Related Quality- of- Life,DDR-QOL）]量表的信效度，为评估饮食治疗对糖尿病患者生活质量的影响提供一种有效的工具。方法翻译并形成中文版DDR—QOL量表，纳入符合条件的患者275例以该中文版量表和汉化版简明健康调查问卷（36 item Short Form HeahhSurvey，SF-36）为研究工具进行资料收集，对该量表的内部一致性、可重复性、结构效度、聚合效度及区分效度等方面进行评价。结果DDR—QOL量表总的Cronbahad为0．86，因子分析结果示DDR—QOL量表具有较好的结构效度，DDR—QOL量表与sF一36具有相关性，DDR—QOL量表能够区分在职与非在职患者的生活质量。结论中文版DDR—QOL量表具有较高的信效度，可为医护人员对进行饮食治疗的糖尿病患者生活质量的评估提供可靠的依据。

Objective To evaluate the reliability and validity of Diabetes Diet-Related Quality-of- Life Scale （DDR-QOL） in Chinese version, in order to provide an efficient instrument for assessing the quality of life of diabetes in diet therapy. Methods Translating and edit the DDR- QOL scale initially, 275 eligible subjects were invited to the study. DDR-QOL scale and 36 item Short Form Health Survey （SF- 36） were used to collect data which were conducted for evaluating the internal consistency, reproducibility, construct validity, convergent and discriminant validity of DDR-QOL. Results The total Cronbach＇s α was 0.86. The factor analysis suggested good construct validity of DDR-QOL. Significant correlations were found between DDR-QOL and SF-36. The quality of life of diabetes who is on the job or not can be identi- fied by DDR-QOL. Conclusions The Chinese version of DDR-QOL is a valid and reliable tool to assess the quality of life of diabetes who are in diet therapy.
