Research Paper

Abstract

The main aim of this research was to evaluate psychometric properties and dimensionality of the Serbian version of the Life Orientation Test-Revised (LOT-R). The sample consisted of 744 youths, with a mean age 18.68 years. Psychometric properties of the Serbian version of the LOT-R were found to be satisfactory. The total scale and both subscales (Optimism and Pessimism) had adequate internal consistency. Convergent validity was demonstrated by moderate correlations with well-being measures (positive and negative affect, life satisfaction, hope, self-efficacy, loneliness and general distress). The results of confirmatory factor analyses yielded two correlated dimensions reflecting optimism and pessimism, and provided support for the two-factor model of optimism. The results of simultaneous multiple regression analyses demonstrated that both optimism and pessimism contributed uniquely to various indicators of well-being. Implications and directions for future research were discussed.
