Psychometric properties and validity of the menopausal rating scale in postmenopausal Portuguese women

Abstract

Objective The aim of the study is to analyze the reliability and validity of the Portuguese version of the Menopause Rating Scale (MRS) among postmenopausal Portuguese women.

Methods A total of 184 postmenopausal women completed the Portuguese MRS. Internal consistency and test-retest reliability were studied. Construct, convergent, and concurrent validity were assessed. The 10-item Cervantes Scale and the Hospital Anxiety and Depression Scale were used to determine convergent and concurrent validity, respectively. The ability and accuracy of the Portuguese MRS to discriminate between women with and without anxiety and depression cases were evaluated, and a receiver operating characteristic curve analysis was used.

Results The Portuguese MRS showed an appropriate level of internal consistency (Cronbach α, 0.84 for MRS total score) and test-retest reliability (MRS total score; intraclass correlation coefficient, 0.92; 95% confidence interval, 0.85–0.96). Factor analysis (construct validity) revealed a 3-factor structure (explained variance of 62.08%). The MRS total score and its 3 factors showed good convergent (10-item Cervantes Scale) and concurrent (Hospital Anxiety and Depression Scale anxiety and depression) validity (all P < 0.001). The Portuguese MRS total score was significantly able to discriminate between postmenopausal women with and without anxiety (P < 0.001) and depression (P = 0.001), with a cutoff point of 15.50 (80.00% sensitivity and 63.70% specificity) for detecting depression and a cutoff point of 16.50 (82.35% sensitivity and 78.57% specificity) for identifying anxiety.

Conclusions The Portuguese MRS has been shown to be a valid and reliable questionnaire for assessing the severity of menopausal symptoms and discriminating among postmenopausal women with and without anxiety and depression.
