MANSUR-ALVES, Marcela et al. Psychometric properties of the Frost Multidimensional Perfectionism Scale for Brazilian adults. Aval. psicol. []. 2022, 21, 2, pp.163-174. ISSN 1677-0471.  https://doi.org/10.15689/ap.2022.2102.18646.04.

The aim of this study was to examine the internal structure, reliability, and temporal stability of the Frost Multidimensional Perfectionism Scale (FMPS) for Brazilian adults. The sample included 1222 participants, with a mean age of 26.57 years (SD=9.03). Half of the sample completed the online version of the instrument, while the other half answered the paper-and-pencil version. To check temporal stability, the instrument was reapplied with 10% of the presential sample. The results from the confirmatory factorial analysis indicated that the original six-dimension model was the best fit for the scale. The internal structure evaluated for the two application formats showed only borderline structural, metric and configuration invariance, highlighting the need for future studies. Both the internal consistency and the temporal stability indices were satisfactory and corroborate the literature findings for the scale in other languages. In conclusion, the FMPS has adequate structural validity and reliability for use in the Brazilian context.
