NEVES, AN et al. Psychometric Properties of Brazilian Portuguese version of the Physical Appearance Perfectionism Scale. CPD [online]. 2019, vol.19, n.1, pp.302-314.  Epub Aug 17, 2020. ISSN 1989-5879.

Perfectionism towards physical appearance considers to be concern about imperfection and hope for perfection in appearance. The aim of this research was to validate the Brazilian Portuguese version of Physical Appearance Perfectionism Scale in a sample of exercise resistance practitioners. The non-probabilistic sample consisted of 534 men and women aged 18 to 39 years. Confirmatory factorial analysis was used to generate psychometric evidence for the reference sample. The two-factor structural model achieved satisfactory adjustment indices, both in the general sample and in the sample by sex. Regarding convergent validity, almost all values of factorial loads were above acceptable, although the average variance extracted (AVE) was adequate only in the male scale. Regarding the discriminant validity, all the AVE values were above the value of the shared variance in the general, female and male models, showing that there are some differences between the two latent variables. Construct reliability was established on both the general scale and the female and male scale. This instrument achieved adequate psychometric evidence for the Brazilian version of Physical Appearance Perfectionism Scale, which allows recommending its use in Brazil.
