Abstract
The purpose of this paper was to adapt and validate the Sport-Multidimensional Perfectionism Scale-2 (SMPS-2) for the Brazilian population using a three-step approach. For content validity, four participants translated the SMPS-2 to Portuguese and six experts adapted the content. Construct validity sample was tested with 395 athletes from a set of individual and team sports. Temporal validity was evaluated with an independent sample of 80 athletes with two data collections. Data analysis was conducted through Content Validity Coefficient (CVC), Cronbach’s alpha, Composite Reliability (CR) and Exploratory (EFA) and Confirmatory (CFA) analyses. Results showed that the Portuguese version contained clear and relevant questions (CVC > .80) and good internal consistency (α > .70/CR > .70); EFA model revealed a four factor solution with 24 items as more satisfying while CFA confirmed the SMPS-2 model with 24 items was adequate. Multi-group analysis showed partial gender invariance. Temporal stability was achieved in all 24 items of the scale (ICC > .75). We concluded that the SMPS-2 is a valid measure for the assessment of perfectionism of the Brazilian sport context.
