ANGELO, D.L. et al. Psychometric Properties of the Perfectionism for Sports Performance Scale (PPS-S) for the brazilian context. CPD [online]. 2019, vol.19, n.2, pp.1-11.  Epub July 13, 2020. ISSN 1989-5879.

The objective of this work was to adapt and validate psychometrically the Performance Perfectionism Scale for Sport (PPS-S) for use in the Brazilian population. This instrument was based on the theoretical model of Hewitt and Flett and developed by Hill, Appleton and Mallinson to measure perfectionism in a specific context of sports performance. The validation of the instrument followed the guidelines for transcultural adaptations of health science measurement instruments. After the intercultural adaptation of the original scale in English, the data were collected from 953 athletes (15-16 years old) of both sexes. The original scale model was tested with confirmatory factorial analysis using the LISREL software (version 9.30). The results revealed a satisfactory fit with 3 factors and 9 items (χ2 = 116.15 p <0.001, RMSEA = 0.063, GFI = 0.974, AGFI = 0.961, NFI = 0.937, CFI = 0.928, NNFI = 915, χ2 / gl = 4.83). Satisfactory tests of internal consistency were also generated through the analysis of factorial loads and t-values. In contrast, Cronbach's alpha test scores and composite reliability were not adequate for the latent variable that refers to self-oriented perfectionism. The extracted mean variance lacked a good fit and only assumed convergent validity in one of the three factors of the instrument. Discriminant validity also suggests little conclusive evidence and, therefore, more studies with other samples of athletes are necessary to better evaluate the psychometric properties of the instrument and to assert its adequate use.
