RESUMEN
OBJECTIVE: The main objective of the study is to translate and adapt the menopause-specific Utian Quality of Life (UQOL) scale to Yoruba, an indigenous Nigerian language, using middle-aged women attending a Family Medicine clinic in Nigeria. METHODS: A total of 322 middle-aged Nigerian women at various menopausal stages were recruited for the study. Their menopausal status was categorized using the Monash Women's Health Program Menopausal Staging Algorithm into pre-, peri-, and postmenopausal groups. The UQOL Yoruba version (YUQOL), Menopause Rating Scale (MRS), and a semistructured sociodemographic questionnaire were interviewer-administered to the women. The collected data were analyzed using IBM SPSS version 21 software. RESULTS: The overall scale and the four subscales of YUQOL all had acceptable internal consistency scores; they also demonstrated good construct and criterion validities, except the YUQOL sexual subscale had poor convergent validity (average variance extracted = 0.23). CONCLUSIONS: This study has validated the YUQOL as a psychometrically sound research instrument for measuring menopause-specific QOL among women undergoing menopausal transition. Its sexual subscale would, however, need to be further tested, preferably in sexually active menopausal women to fully confirm its true psychometric property.
