| 摘要: | The Short Form 36-item (SF-36) and the WHOQOL-BREF questionnaires are commonly used measurements of generic health-related quality of life. The purpose of this study was to compare the psychometric properties of the two questionnaires and to assess their ability to discriminate among different levels of severity groups. A total of 477 (274 males and 203 females) samples aged from 15.2 to 74.7 years (mean = 42.7 ± 12.9) were selected by the question asking subjects if they had diagnosed with a chronic lung disease by a physician using a representative population survey (20855 samples in total) by a proportional probability sampling performed by National Health Promotion Bureau of Taiwan in 2001. The sample subjects were classified into two groups based on the status of whether or not samples had recently taken medication. The WHOQOL-BREF questionnaire can be grouped into 4 domains; physical, psychological, social, and environmental domains. The SF-36 has 8 scales; PF, RF, BP, GH, VT, SF, RE and MH. Score distribution, reliability estimates, discriminating ability and item scaling tests, including Rasch analysis were compared. The WHOQOL-BREF domain scores were less skewed and more homogeneously distributed than SF-36. The range of SF-36 of Cronbach’s alpha was 0.78-0.93, and WHOQOL-BREF 0.74-0.83. Convergent and discriminant validity of SF-36 and WHOQOL-BREF were examined by the Multitrait-Multimethod (MTMM) matrix. For example, the correlation between PH in SF-36 with physical domain in WHOQOL-BREF were substantial in magnitude (r=0.51), while the correlation of PH with social domain was trivial (r=0.16). Rasch analysis results, such as difficulty calibrations in logits, standard error of each calibration and goodness-of-fit statistics were compared for comparable scales between SF-36 and WHOQOL-BREF. Model fit for IRT model was assessed. The receiving operating characteristic (ROC) curves are presented for comparable scales to discriminate between two levels of sev |
