The psychometric properties of the Persian menopause rating scale

Abstract

Background: To measure the severity of menopausal complaints and determine the pattern of menopausal symptoms, a valid and reliable instrument is needed in women's healthcare. The Menopause Rating Scale (MRS) is one of the best-known tools in response to the lack of standardized scales. The purpose of this study was to examine the psychometric properties of the MRS in an Iranian example. Methods: Participants were randomly selected from women referred to healthcare centers in Miandoab, West Azerbaijan, Iran. A total of 330 questionnaires were completed (response rate of 96.9%). Two samples were considered for analysis in the validation process. An exploratory factor analysis (EFA) was conducted on the first sample (n 1 = 165), and a confirmatory factor analysis (CFA) was done using a second study sample (n 2 = 165). The psychometric properties process was concluded with assessment of internal consistency and test-retest reliability. Results: The EFA with Principal Component Analysis extracted three factors explaining 75.47% cumulative variance. The CFA confirmed a three-factor structure of the 11-items MRS. All fit indices proved to be satisfactory. The relative chi-square (χ2/df) was 3.686 (p < .001). The Root Mean Square Error of Approximation (RMSEA) of the model was .04 (90% CI = .105-.150). All comparative indices of the model, including the Comparative Fit Index, Normed Fit Index, and Relative Fit Index, were more than .80 (.90, .87, and .80, respectively). For the overall scale, Cronbach's alpha was .931, whereas the alpha for the subscales ranged from 0.705-0.950. The intraclass correlation was .91 (95% CI = .89-.93), p < 0.001. Conclusion: The results of the study indicate that the Persian model of the MRS is a valid and reliable scale. As a screening tool, the Persian MRS could be used to identify the pattern of symptoms among menopausal, premenopausal, and postmenopausal women to care for and educate them on how to identify and treat the symptoms.

Effect of a hospital-based oral health-education program on Iranian staff: evaluating a theory-driven intervention

“…The experts were asked to review the questionnaire and evaluate each item considering 4 criteria including relevancy, clarity, simplicity, and necessity [ 44 ]. The content validity ratio (CVR) was assessed according to replies to the necessity of questions (nE) and the following formula of CVR was applied: CVR = (nE-N/2)/ (N/2).…”

Menopause Rating Scale (MRS) in the Malay language-translation and validation in a multiethnic population of Selangor, Malaysia

“…For instance, sexual problems and vaginal dryness were classified as somatic, whereas heart problems were classified as urogenital (data not shown). In the validation studies conducted on the Czech, Chinese, and Persian versions of MRS, this loading of domain items was observed to be different from the original version [ 17 , 19 , 29 ]. Such instability in factor structure was noted in a multi-country evaluation study by the authors of the original MRS questionnaire [ 15 ].…”

“…In previous research on translated versions of MRS, confirmatory factor analysis has encountered “straddling" with the factor structure of MRS [ 17 , 19 , 29 ]. To establish the construct validity of Malay language version of MRS, Exploratory Structural Equation Modelling (ESEM) is the recommended statistical approach which integrates the best features of exploratory and confirmatory factor analyses by allowing cross-loadings of items in the analyses while taking on the features of structural equation modelling [ 30 ].…”

“…Cronbach's alpha indicated overall reliability of 0.83 in several countries [ 15 ]. MRS versions in Serbian [ 16 ], traditional Chinese [ 17 ], Urdu [ 18 ], Persian [ 19 ], and Indonesian Bahasa [ 20 ] have demonstrated acceptable reliability and validity.…”

Effectiveness of Educational Intervention Based on Transtheoretical Model on Physical Activity and Menopausal Symptoms

“…Menopause Rating Scale (MRS): Menopause Rating Scale was designed by Heinemann et al [ 32 ]. The Persian version of this questionnaire has been confirmed by Jahangiry et al [ 33 ] was used to the severity of menopausal complaints, and to determine the pattern of menopausal symptoms and their effects on health-related quality of life. It comprises 11 items consisting of three dimensions: somatic symptoms (4 items), psychological symptoms (4 items), and urogenital symptoms (3 items) with responses on a five-point Likert scale with 0 = none , 1 = mild, 2 = moderate, 3 = severe, and 4 = very severe.…”
