dc.description.abstract© 2021. All Rights Reserved.The main objective of this research was to culturally adapt and evaluate the psychometric properties of the Life Orientation Test Revised version for the Brazilian sports context (LOT-R). The sample consisted of 953 young Brazilian athletes of both sexes, with a mean age of 16 years. The results of the confirmatory factor analysis produced two correlated dimensions, reflecting optimism and pessimism, and provided support for a two-factor model. A satisfactory fit was found for LOT-R for sport (LOT-R-Sport) with six items (x2=4.541, df=8; CFI=1; TLI=1; RMSEA=0 [90%IC = 0.000 - 0.024]; SRMR=0.016). Satisfactory tests of internal consistency were also generated through the analysis of factor loadings. The Composite Reliability indices (0.72/ 0.70) were suitable for Optimism and Pessimism, respectively. Motivation, Resilience and Satisfaction with Life showed positive correlations with Optimism and negative correlations with Pessimism, indicative of convergent validity. The configural, metric and scalar invariance was achieved, indicating that the LOT-R-Sport can measure athletes of different sexes, sports, ages and years of experience equally. Although more studies are needed to confirm the psychometric properties of the instrument, the adaptation of the LOT-R-Sport was the first step in the future works about the influence of Optimism on sports performance.
