The aim of this research was to review the psychometric properties of the Frost Multidimensional Perfectionism Scale(FMPS) in a non-clinical sample of 1,242 Mexican adults. The reliability and validity of the scale were assessed usingfactorial analyses, and Cronbach’s alpha (α) and McDonald’s omega (ω) indices were analyzed. The overall reliabilityof the scale was excellent (α = .928, ω = .928), with specific dimensions ranging from acceptable to excellent (concernover mistakes: α = .899, ω = .903; organization: α = .892, ω = .896). Exploratory factor analysis confirmed theadequacy of the data (KMO = .940, p < .001), with the final model fitting with five factors explaining 59.390% of thevariance. Confirmatory factor analysis yielded an RMSEA of .074, CMIN/DF of 7.882, GFI of .849, and CFI of .871,indicating acceptable but not excellent fit. These results suggest that the ...
