The Persian Version of Menopause Rating Scale (MRS): A Psychometric Study

Objective: Menopause-related symptoms can strongly affect health-related quality of life (HRQOL) in most peri-menopausal women. The aim of the present study was to explore the psychometric properties of a culturally adapted and translated Persian version of the Menopause Rating Scale (MRS). Study Design: The study was conducted on a random sample of 270 middle-aged women (age range 40-60 yrs) selected from 25 urban health service centers across Tabriz, Iran. Content validity was evaluated by a panel of 11 experts. Construct validity was assessed by exploratory factor analyses with Varimax rotation and principal axis factoring extraction method and by confirmatory factor analyses. Internal consistency and test-retest reliability were assessed with Cronbach's alpha and intra-class correlation coefficient (ICC), respectively. In addition, the feasibility of the measure was judged based on ceiling and floor effects. Results: Content validity of the measure was good with a mean content validity index (CVI) and mean content validity ratio (CVR) of 0.88 and 0.94, respectively. Exploratory factor analyses identified three factors accounting for 47.69% of the variance. Confirmatory factor analyses found the original three-factor model to have the best fit to the data. Cronbach's alpha coefficient (0.85) and the test-retest reliability score (0.91) indicated good internal consistency. Conclusion: The Persian version of the MRS demonstrated excellent reliability and validity. It can therefore be used in both clinical and research settings to assess menopause-related symptoms and associated quality of life.
