LARANJEIRA, Carlos António. Portuguese translation and validation of the revised life orientation test (LOT-R). Univ. Psychol. [online]. 2008, vol.7, n.2, pp.469-476. ISSN 1657-9267.

In this work we describe the adaptation for the European Portuguese language of the Revised Life Orientation Test (LOT-R), which allows the evaluation of Dispositional Optimism as a steady characteristic. After having been translated both ways with the support and help of experts in the area, LOT-R was applied to a sample of university students (N=790), and the respective internal consistency, construct validation and concurrent validity were properly assessed. The detected psychometric properties substantiate the quality of such a tool. Factorial analysis shows that the structure of a factor is the most suitable similarly to the factorial structure found in the source model. The positive correlation between LOT-R and the Instrumental and Expressive Social Support Scale (IESSS) confirms the hypothesis about the criterion validity.
