Development and verification of the Menopause Emotional Symptom Questionnaire

OBJECTIVE: A detailed, well-validated scale for measuring emotional symptoms in menopausal women is lacking. We aimed to develop the Menopause Emotional Symptom Questionnaire (MESQ) and to confirm its reliability and validity among Koreans. METHODS: Eighteen primary items based on previous research results were selected using exploratory factor analysis and confirmatory factor analysis (CFA). New data, including answers to the novel MESQ, Menopause Rating Scale, Kupperman Index, Beck Depression Inventory-II, and Beck Anxiety Inventory, were collected from 200 perimenopausal women and 100 young men through a research company. Exploratory factor analysis and CFA were performed again to determine whether the MESQ accurately measures emotional symptoms in perimenopausal women. Receiver operating characteristic curve and k-means cluster analyses were used to identify the most appropriate cutoff value. RESULTS: The MESQ showed high internal consistency (Cronbach α = 0.926), and the CFA revealed that the factor structure comprised two subscales: nine items for mood/anxiety symptoms and four items for sleep symptoms. A high correlation between the total MESQ score and total scores of the existing scales was confirmed, indicating high convergence validity. Comparison of the mean MESQ scores between men and women showed significant sex difference, indicating secure known-group validity. The cutoff point of the total MESQ score between the high-risk and low-risk groups was 26. CONCLUSIONS: The novel MESQ has high validity and reliability, and this study confirmed that the MESQ is a valid tool for screening for and measuring emotional symptoms in menopausal women in Korea.
