Reliability and validity of the Menopausal Symptom Scale

Area of Science:

• Reproductive Health
• Psychometrics
• Sociology of Health

Background:

• Menopausal symptom experiences vary significantly across racial and ethnic groups.
• Healthcare providers require culturally sensitive instruments to accurately assess menopausal symptoms.

Purpose of the Study:

• To evaluate the psychometric properties of the Menopausal Symptom Scale in Korean women.
• To determine the validity and reliability of the scale for this specific demographic.

Main Methods:

• Convenience sampling of 229 Korean women aged 40-65.
• Evaluation of content validity, item analysis, construct validity, discriminant validity, criterion-related validity, floor/ceiling effects, and internal consistency reliability.
• Exploratory and confirmatory factor analyses were performed.

Main Results:

• Factor analysis identified four factors explaining 65% of the variance.
• The scale demonstrated strong discriminant and criterion-related validity.
• No significant floor or ceiling effects were observed, with Cronbach's alpha values ranging from 0.90 to 0.95.

Conclusions:

• The Menopausal Symptom Scale is a valid and reliable instrument for Korean menopausal women.
• The scale appears to capture culturally-specific psychological symptoms in menopausal women from Asian or traditional cultures.
• Further research across diverse ethnic groups and countries is recommended to confirm psychometric properties.
