基于格林模式突发性聋患者生活质量影响因素问卷的编制

Development of questionnaire on influencing factors of quality of life in patients with sudden deafness based on Green model

目的:编制信效度良好且能全面评估突聋患者生活质量影响因素的问卷。方法:以格林模式为理论框架,在文献回顾、小组讨论、半结构访谈及专家函询的基础上编制初始问卷。于2018-05-2019-04采用方便抽样法,选取山西省2所综合性三级甲等医院耳鼻咽喉头颈外科170例突聋患者进行调查。通过临界比值法、相关分析法对各条目数据进行整理分析;通过探索性因子分析检测问卷的结构效度;通过专家函询检测问卷的内容效度;通过计算Cronbach’sα系数和进行问卷重测确定问卷的信度,最终形成正式问卷。结果:基于格林模式编制的突聋患者生活质量影响因素问卷包含知识因素、态度因素、行为因素、促成因素、强化因素5个维度、31个条目。项目分析结果显示,各条目临界比值为8.09~44.77(P<0.05);除条目8、11、13外,其余条目得分与总分Pearson相关系数均>0.3。问卷的KMO值为0.844,Bartlett’s球形检验χ~2值为3218,P<0.001。运用主成分分析法共提取出5个公因子,分别命名为知识因素、态度因素、行为因素、促成因素、强化因素,累积方差贡献率为60.905%。问卷水平的内容效度指数为0.955,条目水平的内容效度指数为0.786~0.981;问卷水平的Cronbach’sα系数为0.875,各维度的Cronbach’sα系数为0.780~0.912;问卷水平的重测信度为0.88,各维度的重测信度为0.810~0.913。结论:基于格林模式编制的突聋患者生活质量影响因素问卷具有良好的信效度,可作为评估突聋患者生活质量影响因素的工具。

Objective:To develop a questionnaire with good reliability and validity that can comprehensively evaluate the influencing factors of life quality of patients with sudden deafness.Method:Based on the Green model and literature review,group discussions,semi-structured interviews and Delphi expert inquiries,an initial questionnaire was developed.From May 2018 to April 2019,170 patients with sudden deafness in otolaryngology head and neck surgery in 2 comprehensive tertiary level A hospitals in Shanxi Province were selected for investigation by convenient sampling method.Through the critical ratio method and correlation analysis method,the data of each item are sorted and analyzed.The structural validity of the questionnaire was tested by exploratory factor analysis.The content validity of the questionnaire was evaluated by calculating the content validity index through expert inquiry.The reliability of the questionnaire was determined by calculating Cronbach’sαcoefficient and retesting the questionnaire,and finally a formal questionnaire was formed.Result:The questionnaire on influencing factors of life quality for patients with sudden deafness based on Green model includes 5 dimensions and 31 items including knowledge factors,attitude factors,behavior factors,contributing factors and reinforcement factors.The results of project analysis showed that the critical ratio of each item was 8.09-44.77(P<0.05).Except items 8,11 and 13,the pearson correlation coefficient between the other items and the total score is>0.3.The KMO value of the questionnaire was 0.844,and the 2 value of Bartlett’s spherical test was 3218,P<0.001.Using the principal component analysis method,five common factors were extracted,named as knowledge factor,attitude factor,behavior factor,contributing factor and reinforcing factor,respectively,the cumulative variance contribution rate was 60.905%.The content validity index of the questionnaire level was 0.955,the content validity index at item level is 0.786-0.981;Cronbach’sαcoefficient at the questionnaire level was 0.875,Cronbach’sαcoefficient of each dimension is 0.780-0.912;The retest reliability of the questionnaire level was 0.88,the retest reliability of each dimension is 0.810-0.913.Conclusion:The questionnaire on influencing factors of quality of life for patients with sudden deafness based on Green model has good reliability and validity,and can be used as a tool for evaluating influencing factors of quality of life for patients with sudden deafness.
