The Development and Assessment of the Quality of Life Instrument for Hepatitis B Patients / 中国心理卫生杂志

ABSTRACT

Objective: To develop a quality of life instrument for hepatitis B patients(QOL-HBV) and examine it's reliability and validity.Methods:The item analysis, construct validity, content validity, criteria validity, reliability and discriminate were assessed by a survey on 134 HBV patients with QOL-HBV.Results:Item analysis showed that QOL-HBV had satisfactory item discrimination. Eight common factors were extracted by exploratory factor analysis and they can be reduced to three domains. The ?2/DF was 1.310, GFI was 0.972 and AGFI was 0.967 by the confirmatory factor analysis. The coefficients of Cronbach's ? of the instrument and all domains were above 0.80. In comparison with SF-36, there was good correlation among corresponding domains.Conclusion:QOL-HBV is a good scale in testing the quality of life, which has good reliability and validity.
