The Menopause Rating Scale (MRS) scale: a methodological review.

Area of Science:

• Reproductive Medicine
• Psychometrics
• Women's Health

Background:

• The Menopause Rating Scale (MRS) is a self-administered questionnaire designed for aging women.
• It assesses menopausal symptoms, their severity, and changes related to hormone replacement therapy.
• The MRS is available in 10 languages and widely adopted internationally.

Purpose of the Study:

• To provide a comprehensive evaluation of the psychometric properties of the Menopause Rating Scale (MRS).
• To analyze the reliability and validity of the MRS across diverse populations.
• To establish the scale's suitability for international comparative studies.

Main Methods:

• A large-scale multinational survey across 9 countries (2001/2002) formed the primary dataset.
• Test-retest reliability was assessed using smaller convenience samples.
• Data were centrally analyzed, with HRT study data used for discriminative validity.

Main Results:

• The MRS exhibited good reliability (consistency and test-retest stability) across participating countries.
• The scale's internal structure was consistent, indicating it measures the same phenomenon globally.
• Good correlations were observed with the Kupperman Index and SF-36, supporting criterion-oriented and construct validity.

Conclusions:

• Methodological evidence supports the MRS as a high-quality instrument for measuring and comparing HRQoL in aging women.
• The scale demonstrates high reliability and validity for assessing menopausal symptoms.
• The MRS is suitable for intra-individual comparisons in clinical trials and cross-regional studies.
