Abstract: | 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 α 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. |
