ORTIZ, Manuel S; GOMEZ-PEREZ, Daniela; CANOINO, Margarita  y  BARRERA-HERRERA, Ana. Validation of the Spanish Version of the Life Orientation Test-Revised (LOT-R) in a Chilean sample of college age students. Ter Psicol [online]. 2016, vol.34, n.1, pp.53-58. ISSN 0718-4808.  http://dx.doi.org/10.4067/S0718-48082016000100006.

Optimism is a variable associated with better physical and mental health outcomes. Thus, a valid and reliable measure that account for this construct is needed. Therefore, this study had as purpose to confirm the factorial structure, and reliability of the Life Orientation Test-Revised Spanish version with a large sample of 526 Chilean College age students (Mage = 21 years old; 65% Male). A Confirmatory Factor Analysis, with Maximum Likelihood, and Satorra-Bentler correction was performed. The internal consistency was estimated with Cronbach Alpha. The results confirmed a single factor solution with six indicators, and factorial loadings greater than .35. The overall goodness of fit is excellent, and the internal consistency was adequate (.72). These results, in addition to the short lenght of the scale, suggest that the LOT-R is a valid and reliable measure of optimism that can be easyly used with Chilean population.
