肠造口患者生活质量量表的编制与应用

Development and application of the Quality of Life Scale for Enterostomy Patients

目的研制符合我国文化背景及医疗体系的肠造口患者生活质量量表。方法通过文献回顾、头脑风暴、专家函询等方法形成初试版量表。采用便利抽样法,选取2018年7月—2019年2月在西安交通大学第一附属医院、西安交通大学第二附属医院、陕西省人民医院、空军军医大学西京医院、空军军医大学唐都医院5所三级甲等医院的212例肠造口患者进行现场调查。使用条目筛选方法形成终版量表,并对其进行信度、效度的评价。结果最终版量表提取6个公因子分属于3个维度,共30个条目,解释变异量的61.7%,总量表的Cronbach’s α系数为0.921,分半信度系数为0.945,各维度的Cronbach’s α系数为0.731~0.899,分半信度系数为0.757~0.936。条目内容效度为0.82~1.00,与效标造口患者生活质量量表总分的相关系数为0.756,各维度及维度与总分之间的Spearman相关系数为0.282~0.739(均P<0.01)。结论肠造口患者生活质量量表具有良好的信效度,可用于我国文化背景下的肠造口患者生活质量评估。

Objective To develop a Quality of Life Scale for Enterostomy Patients in lines with my country's cultural background and medical system.Methods The initial version of the scale was formed through literature review,brainstorming,and the expert consultation.From July 2018 to February 2019,we selected 212 enterostomy patients from five ClassⅢGrade A hospitals,namely the First Affiliated Hospital of Xi'an Jiaotong University,the Second Affiliated Hospital of Xi'an Jiaotong University,Shaanxi Provincial People's Hospital,Xijing Hospital of Air Force Medical University and Tangdu Hospital of Air Force Medical University for field investigation by convenient sampling.We formed the final scale with the method of item screening,and evaluated its reliability as well as validity.Results The final version of the scale extracted six common factors belonging to three dimensions,a total of 30 items,explaining 61.7%of the variance.The Cronbach'sαcoefficient of the total scale was 0.921,the split-half reliability coefficient was 0.945;Cronbach'sαcoefficients of each dimension ranged from 0.731 to 0.899,and split-half reliability coefficients were from 0.757 to 0.936.The item content validity ranged from 0.82 to 1.00,and the correlation coefficient with the criterion,the total score of the Standardized Quality of Life Scale for Ostomy Patients was 0.756.The Spearman correlation coefficients among dimensions,as well as between dimension and total score were from 0.282 to 0.739(all P<0.01).Conclusions The Quality of Life Scale for Enterostomy Patients has good reliability and validity which can be used to evaluate the quality of life of enterostomy patients under the cultural background of our country.
