Area of Science:

• Reproductive Medicine
• Psychometrics
• Women's Health

Background:

• The menopausal transition involves various symptoms impacting women's quality of life.
• Accurate symptom measurement is crucial for effective clinical assessment and research.
• Existing tools may not fully capture the complexity of menopausal symptoms.

Purpose of the Study:

• To present the Midlife Women's Symptom Index (MSI), a new scale for menopausal transition symptoms.
• To evaluate the psychometric properties, including reliability and validity, of the MSI.
• To provide a validated instrument for assessing midlife women's menopausal symptoms.

Main Methods:

• Cross-sectional study design.
• Expert review by 20 women's health experts.
• Psychometric testing on 77 middle-aged women using the MSI and Menopausal Symptom Checklist (MSC).
• Data analysis included descriptive statistics, K-R 20, and item analysis.

Main Results:

• Expert review contributed to the scale's content validity.
• The MSI demonstrated acceptable reliability (K-R 20).
• Item analysis supported the scale's internal structure.
• The study found the MSI to be a reliable and valid measure for middle-aged women.

Conclusions:

• The Midlife Women's Symptom Index (MSI) is a psychometrically sound instrument.
• The MSI can be reliably used to assess symptoms during the menopausal transition.
• This validated tool aids in understanding and managing menopausal symptom experiences.
