Optimism, self-esteem and personality: adaptation and validation of the Brazilian Version Of The Revised Life Orientation Test (LOT-R)

Abstract

Optimism can be defined in terms of positive and negative expectations regarding future life events. The aims of this study were to adapt and validate the Revised Life Orientation Test (LOT-R) for the Brazilian population, verify its psychometric characteristics, assess whether there are gender differences, and verify its relationships with self-esteem and personality. The participants were 844 university students from two public universities in the southern of Brazil, which answered the following tests: LOT-R, Rosenberg Self-Esteem Scale and Baterial Fatorial de Personalidade (BFP). Factor analysis extracted a single factor, corroborating the findings of the original scale and indicating that optimism and pessimism are probably polar opposites of a single continuum. The results showed positive correlation between self-esteem and optimism in life orientation, and negative correlation between optimism and neuroticism. In conclusion, the Brazilian version of the LOT-R is an instrument that presents appropriate psychometric characteristics and that is ready for use in the Brazilian population.
