The aim of the study was to adapt the Moorehead–Ardelt Quality of Life Questionnaire II (MA-II) into Turkish and validate it in bariatric patients.
Methods:
Special tools are needed to assess the impact of increasing worldwide obesity on quality of life. MA-II is a widely used tool to assess quality of life in obese patients. The scale adaptation standards of the World Health Organization were applied for translation and adaptation of MA-II. To test the validity, factor analysis, concurrent and predictive validity and to evaluate the correlation between MA-II and Short Form 36 Quality of Life Questionnaire (SF-36), the Pearson correlation coefficient was used. The reliability of MA-II was evaluated using internal consistency, item analysis, and test–retest methods.
Results:
The study was carried out with 185 adult patients undergoing planned bariatric surgery. MA-II confirmed the original factor structure with six items, and the factor loadings of items varied between 0.61 and 0.80. The Cronbach alpha coefficient of MA-II was 0.83, and the internal consistency of scale was found to be high. There was a statistically significant relationship between SF-36 and scale items. Furthermore, there was a statistically significant negative correlation between MA-II and body mass index.
Conclusion:
The Turkish version of MA-II is a valid and reliable tool for bariatric patients.
