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 (n1?=?165), and a confirmatory factor analysis (CFA) was done using a second study sample (n2?=?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 (?2/df) was 3.686 (p?

Project description:BackgroundMenopause Rating Scale (MRS) evaluates eleven menopausal symptoms and health related quality of life (HRQOL) of postmenopausal women under three subscales. In this study we attempted cross cultural adaptation and evaluation of psychometric properties of a Sinhala translation of MRS.MethodsSinhala version of MRS was adapted following standard methodology; forward and backward translations, review by an expert group, focus group discussion (FGD) and pre-testing. It was self-administered among randomly selected healthy, Sinhalese, community-dwelling 166 postmenopausal women (aged; median?=?56.5, IQR, 53.0-59.0 years) along with the Short Form 36 (SF-36) survey questionnaire. MRS was re-administered among a subsample (n?=?80) after two weeks of first administration. Psychometric properties; reliability and validity were evaluated.ResultsIn Sinhala version of MRS, both internal consistency (Cronbach's alpha coefficient?=?0.79) and test retest reliability (intra class correlation / ICC?=?0.86, 95%CI?=?0.82-0.91, p?<?0.001 and Pearson correlation / r?=?0.93) were high. Factor analysis (FA) with Principal Component Analysis (PCA) extracted three factors explaining 59.82% cumulative variance with few exceptions from the original version. In the item-subscale correlation analysis items showed stronger correlations within their own subscale score (r range between 0.56-0.84) than with other subscales scores and subscales' scores showed strong correlations with the overall MRS score (r range between 0.70-0.86) indicating strong convergent validity. Mean (SD) symptom severities of each item were significantly different between symptomatic and asymptomatic women (p?<?0.05) emphasizing good discriminant validity. The overall MRS and SF-36 scores correlated significantly (Pearson correlation: -?0.52, p?<?0.01 and Kendall's tau-b: -?0.39, p?<?0.01) ensuring strong criterion validity.ConclusionsThe Sinhala version of MRS we adapted is an informative tool with high reliability and validity and this tool can be used to evaluate the menopausal symptoms and HRQOL in postmenopausal women conversant in Sinhala.

Project description:Pain intensity and patients' impression of global improvement are widely used patient-reported outcome measures (PROMs) in clinical practice and research. They are commonly assessed using the Numerical Pain Rating Scale (NPRS) and Global Rating of Change (GROC) questionnaires. The GROC is essential as an anchor for evaluating the psychometric properties of PROMs. Both of these PROMs are translated to many languages and have shown excellent psychometric properties. Their availability in Nepali would facilitate pain research and cross-cultural comparison of research findings. Therefore, the objectives of this study were to translate and cross-culturally adapt the NPRS and GROC into Nepali and to assess the psychometric properties of the Nepali version of the NPRS (NPRS-NP).After translating and cross-culturally adapting the NPRS and GROC into Nepali using recommended guidelines, NPRS-NP was administered to 104 individuals with musculoskeletal pain twice. The Nepali version of the GROC (GROC-NP) was administered at the follow-up for anchor-based assessment. (1) Test-retest reliability and minimum detectable change (MDC) among the stable group, (2) construct validity (by single sample t-test within the improved group and independent sample t-test between groups), and (3) concurrent validity were assessed. Receiver operating characteristic (ROC) curves were plotted to determine the responsiveness of the NPRS-NP using the area under the curve (AUC), and minimum important changes (MIC) for small, medium and large improvements.Significant cultural adaptations were required to obtain relevant Nepali versions of both the NPRS and GROC. The NPRS-NP showed excellent test-retest reliability and a MDC of 1.13 points. NPRS-NP demonstrated a good construct validity by significant within-group difference in mean of NPRS score- t(63)= 7.57, P?<?0.001 and statistically significant difference of mean score- t(98)= -4.24, P?<?.001 between the stable and improved groups. It demonstrated moderate concurrent correlation with the GROC-NP; r?=?0.43, P?<?0.01. Responsiveness of the NPRS-NP was shown at three levels with AUC?=?0.68-0.82, and MIC?=?1.17-1.33.The NPRS and GROC were successfully translated and culturally adapted into Nepali. The NPRS-NP demonstrated good reliability, validity and responsiveness in assessing musculoskeletal pain intensity in a Nepali population.
