ABSTRACT
PURPOSE:
To investigate the weight loss effects with higher sensitivity, disease specific quality of life (QoL) instruments were important. The Moorehead-Ardelt quality of life questionnaire II (MA-II) is widely used, because it was simple and validated the several languages. The aims of present study was performed the translation of MA-II Korean version and the validation compared with EuroQol-5 dimension (EQ-5D), obesity-related problems scale (OP-scale), and impact of weight quality of life-lite (IWQoL-Lite).METHODS:
The study design was a multicenter, cross-sectional survey and this study was included the postoperative patients. The validation procedure is translation-back translation procedure, pilot study, and field study. The instruments of measuring QoL included the MA-II, EQ-5D, OP-scale, and IWQoL-lite. The reliability was checked through internal consistency using Cronbach alpha coefficients. The construct validity was assessed the Spearman rank correlation between 6 domains of MA-II and EQ-5D, OP-scale, and 5 domains of IWQoL-Lite.RESULTS:
The Cronbach alpha of MA-II was 0.763, so the internal consistency was confirmed. The total score of MA-II was significantly correlated with all other instruments; EQ-5D, OP-scale, and IWQoL-Lite. IWQoL-lite (rho = 0.623, P < 0.001) was showed the strongest correlation compared with MA-II, followed by OP-scale (rho = 0.588, P < 0.001) and EQ-5D (rho = 0.378, P < 0.01).CONCLUSION:
The Korean version MA-II was valid instrument of measuring the obesity-specific QoL. Through the present study, the MA-II was confirmed to have good reliability and validity and it was also answered simple for investigating. Thus, MA-II could be estimated sensitive and exact QoL in obesity patients.
