The present study aimed to (1) develop a questionnaire based on the OxFAB taxonomy, specifically adapted for middle-aged women\u2014the OxFAB-MAW\u2014stage of life and sex, which present a high incidence of obesity, (2) assess the psychometric properties of this tool, and (3) evaluate the discriminative power of the OxFAB-MAW (normal weight vs. obesity).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Overall, 1,367 Portuguese middle-aged women between 45 and 65 years (<jats:italic>M<\/jats:italic> = 52.3, <jats:italic>SD<\/jats:italic> = 5.15) filled in a sociodemographic, health, and menopause-related questionnaire, as well as the OxFAB-MAW.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Confirmatory factor analysis demonstrated an acceptable model fit (comparative fit index = 0.928, Tucker\u2013Lewis index = 0.913, root mean square error of approximation = 0.072, and standardized root mean square residual = 0.054).
