O perfeccionismo direcionado à aparência física considera haver preocupação com a imperfeição e esperança para a perfeição em relação à aparência. O objetivo dessa pesquisa foi validar a versão em português Brasileiro da Physical Appearance Perfectionism Scale em uma amostra de praticantes de exercícios resistidos. A amostra não-probabilística foi constituída por 534 homens e mulheres com idades entre 18 a 39 anos. Foi utilizadaanálise fatorial confirmatória, para gerar evidencias psicométricas para a amostra de referencia. O modelo estrutural bifatorial alcançou índices de ajuste satisfatório, tanto na amostra geral, quanto na amostra por sexo. Em relação à validade convergente, quase todos os valores das cargas fatoriais estavam acima do aceitável, mas a variância média extraída foi adequada apenas na escala masculina. Quanto à validade discriminante, todos os valores da AVE estiveram acima do valor da variância compartilhada nos modelo geral, feminino e masculino, demonstrando haver alguma diferença as duas variáveis latentes. A confiabilidade de constructo foi estabelecida tanto na escala geral, quanto na escala feminina e masculina. O presente instrumento obteve evidencias psicométricas adequadas para a versão brasileira da Physical Appearance Perfectionism Scale, o que permite recomendar seu uso no Brasil. 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 model, female and male, 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.
