Optimism and pessimism are conceptualized as generalized expectations about events happening in people's lives, and are regarded as stable dispositions. The construct of optimism can be understood as being one-dimensional and bipolar, in other words, it's an only attribute with two extremes ranging from optimism or pessimism. The Revised Life Orientation Test (LOT-R) is the instrument used for assessing dispositional optimism and has been the subject of several studies that verify its one-dimensionality. However, the results of those studies do not necessarily support the theoretical model. The aim of this paper was to analyze the factor structure of the LOT-R in a sample of adolescent students from basic primary and secondary education. Participants were 183 students of both genders, aged between 13 and 19 years old. The application of the LOT-R was carried collectively in the classroom. The instrument's confirmatory factor analysis was performed by testing a one-factor model and another one of two-factors. The two-factor model was the most appropriate, showing that, for this particular sample, the LOT-R consists of two components. The need for studies to test the structure of the instrument is evident inasmuch as the literature indicates that cultural differences are key elements to understanding optimism.
