The transcultural validation of the Revised Life Orientation Test (LOT-R) was implemented and the psychometric properties of this test were examined in the Brazilian context. This test evaluates the construct of dispositional optimism, in terms of outcome expectancies concerning future life events. The LOT-R was first submitted to a back translation and to a pilot study in order to make its transcultural adaptation. Then, a sample of 396 university students answered this test and the Beck Depression Inventory (BDI). A retest was implemented 30 days later in a randomly selected sub-sample of 48 students. Results showed a significant test-retest correlation (r = 0,61) and good internal consistency (alpha = 0,68). Degree of optimism was predictive of fewer degree of depressive symptoms (r = -0,42). Exploratory factorial analysis identified one factor explaining 39,78 % of variance. The results demonstrated good psychometric properties for the Brazilian version of the LOT.
