ABSTRACT

The Short Form Health Survey SF-36 is a well-known generic health-related quality of life measure that has widely been used worldwide. However, given the cultural, social and ethnic differences in some countries, it might not follow the intended structure of the instrument. Hence, this study aims to determine the psychometric properties of the Malay version of Short Form Health Survey (SF-12) among postpartum mothers. A cross-sectional study was conducted among 1-month postpartum mothers attending Obstetric and Gynecology clinic, Universiti Sains Malaysia Hospital, Kelantan, Malaysia. Reliability was estimated using internal consistency and the factor structure was extracted by performing confirmatory factor analysis using SPSS v. 20 and AMOS v. 20. A total of 108 women responded. The mean (SD) score for the Physical Component Summary (PCS) score and Mental Component Summary (MCS) score were 43.3 (7.08) and 42.4 (6.87) respectively. The Cronbach alpha for PCS-12 was 0.749 and MCS-12 was 0.701. Spearman correlations of individual items and the SF-12 component summary scores showed PF, RP, BP and GH items correlated higher with the PCS score, whereas the VT, SF, RE, and MH items correlated higher with the MCS score lending support to its good convergent validity. The confirmatory factor solution showed final model with two factors structure and six items each with acceptable factor loadings, satisfactory absolute and parsimonious fitness (RMSEA=0.1, x2/df=2.4). The psychometric tests of the Malay version of SF-12 generally showed acceptable validity and reliability among postpartum women.
