摘要：

目的  探讨德国护养院居住者主观生活质量量表中文译本用于上海护养院居住者主观生活质量测量的可行性、信度和效度。方法  通过分层整群抽样的方法，对330名护养院居住者进行问卷调查，对其中56名被调查者进行重测，评价量表的可行性、内部一致性信度、重测信度、结构效度、标准关联效度和区分效度。结果  被调查者完成量表的平均时间为(24.14±9.53) min（<30 min），可行性良好。量表总分的内部一致性信度系数（Cronbach’ α）为0.776，各个维度的Cronbach’ α均>0.7，提示量表内部一致性信度良好，可用于本次生活质量测量。量表总分的重测相关系数(ICC)为0.698（P<0.001）。在验证性因子分析中，近似误差均方根(RMSEA)为0.080，拟合优度指数(CFI)为0.601（χ2=2 931.5，P<0.001)，说明测量结果符合量表的构想，有较好的结构效度。以被调查者自评生活满意度为标准，生活质量总分与生活满意度相关系数为0.234 7（P<0.001)，表示生活质量总分与生活满意度呈正相关，量表的标准关联效度可以接受。非参数检验结果显示，不同心情对被调查者生活质量总分有显著影响（χ2=7.961，P<0.001），每两个相邻等级的Cohen’ s d值都在0.5以上，表明量表有良好的区分效度。结论  德国护养院居住者主观生活质量量表中文译本具有良好的可行性、内部一致性信度、重测信度、结构效度和区分效度，具有可以接受的标准关联效度。但在广泛应用之前，尚需在更多地区人群中进行研究。

Abstract:

Objective  To investigate the feasibility, reliability and validity of applying the Chinese version of German Questionnaire for the Subjective Life Quality of Inhabitants in Nursing Homes to the evaluation of the subjective life quality of inhabitants in Shanghai nursing homes. Methods  Stratified cluster sampling was adopted and a total of 330 inhabitants of nursing homes were surveyed by the questionnaire. Among them, 56 respondents were resurveyed. The feasibility, reliability of internal consistence and retest, structural validity, standard correlation validity, and discriminant validity of the questionnaire were evaluated. Results  The mean time for respondents to complete the questionnaire was (24.14±9.53) min (<30 min) and the feasibility was satisfactory. The reliability coefficient of internal consistence (Cronbach’α) was 0.776 and Cronbach’α coefficients of all domains were >0.7, which indicated that the reliability of internal consistence was satisfactory and could be used for the survey of life quality. The test-retest correlation coefficient of total score was 0.698 (P<0.001). In confirmatory factor analysis, root mean square error of approximation (RMSEA) was 0.080 and comparative fit index (CFI) was 0.601 (χ2=2 931.5，P<0.001), which meant that the results of survey met the purpose of questionnaire and the structural validity was satisfactory. The life satisfaction evaluated by respondents was adopted as the criterion and the correlation coefficient between the total score of life quality and life satisfaction was 0.234 7 (P<0.001), indicating the total score of life quality positively correlated with life satisfaction and the standard correlation validity was acceptable. The results of nonparametric test showed that different moods significantly affected the total score of life quality of respondents (χ2=7.961，P<0.001). Cohen’s d values of any two adjacent levels were greater than 0.5, which showed that the discriminant validity was satisfactory. Conclusion  The feasibility, reliability of internal consistence and retest, structural validity, and discriminant validity of Chinese version of German Questionnaire for the Subjective Life Quality of Inhabitants in Nursing Homes are satisfactory and the standard correlation validity is acceptable. However, further research in more areas should be conducted before it can be widely used.
