This study documents the validation study of the Multicultural Quality of Life Index, Chinese version (MQLI-Ch). This self-rated instrument is composed of ten items that correspond to multiple dimensions of the concept of quality of life. Each item is rated on a scale from 1 to 10, according to the subject's culture-informed understanding of the concept. The MQLI-Ch was tested on 144 Chinese subjects (124 psychiatric patients and 20 professionals). It was found to be quite efficient (about 3 min to be completed) and easy to use. A Cronbach's alpha of 0.94 demonstrated its internal consistency. The factor analysis of the ten items yielded one single factor, which accounted for 65.19% of the variance. The test-retest reliability correlation coefficient was 0.80. Its discriminant validity was documented by a highly significant difference (P < 0.001) between the mean scores of the two samples with presumed differences in quality of life. Thus, the MQLI-Ch showed high feasibility, internal structure, reliability and discriminant validity.
本研究记录了《多元文化生活质量指数》中文版（MQLI-Ch）的效度研究。这个自评工具由十个项目组成，这些项目对应于生活质量概念的多个维度。根据受试者基于文化的概念理解，每个项目按1至10分进行评分。MQLI-Ch在144名中国受试者（124名精神科患者和20名专业人员）身上进行了测试。结果发现它效率颇高（大约3分钟即可完成）且易于使用。克朗巴哈系数为0.94，表明其内部一致性良好。对这十个项目进行因子分析得出一个单一因子，该因子解释了65.19%的方差。重测信度相关系数为0.80。生活质量假定存在差异的两个样本的平均得分之间存在高度显著差异（P < 0.001），证明了其区分效度。因此，MQLI-Ch显示出较高的可行性、内部结构、信度和区分效度。
