OBJECTIVE: The study aimed to assess the psychometric properties of the Menopause-specific Quality of Life Questionnaire (MENQOL) in Serbian climacteric women. METHODS: Two hundred mid-aged (40-65 years) women filled out a general sociodemographic and medical questionnaire, the MENQOL, the Short Form-36 questionnaire (SF-36), and Beck's Depression Inventory (BDI). The MENQOL was translated according to recommended methodology and its psychometric properties (internal consistency, discriminant, construct and criterion validity, factor and Rasch analyses) were assessed. RESULTS: Cronbach's alpha coefficient for the Serbian MENQOL was 0.957 (Vasomotor =0.917, Psychosocial =0.907, Physical =0.928, Sexual =0.913). Corrected item-total correlation coefficients were >0.50 for all items. Factor analysis extracted six domains with total variance of 72.02%. Beside the four original domains, two new domains were observed: Attractiveness and Pain. Factor loadings for all items were appropriate (>0.4). The MENQOL correlated with the SF-36 and BDI total scores, suggesting good criterion validity. Rasch analysis showed adequate reliability (item =0.91; person =0.79) and separation (item =1.95; person =3.21) indexes, proving good reproducibility and reliability of the Serbian MENQOL. All items had infit and outfit mean squares in the standard accepted range. CONCLUSION: Principal component analysis showed somewhat different constructs from the original scale. However, Rasch analysis confirmed that the MENQOL represents a good metric instrument for menopausal symptoms.
