Abstract	The life orientation test-revised (LOT-R) (Scheier et al. in "Journal of Personality and Social Psychology" 67:1063-1078, 1994) is a brief measure for assessing dispositional optimism. The aim of this study was to develop a Greek language version of the LOT-R and to assess the instrument's psychometric properties. The LOT-R was translated and culturally adopted in Greek language, and the final version was administered, along with a questionnaire consisting socioeconomic characteristics and a single item measuring optimism, to 276 Greek speaking, hospital nurses (222 female, 54 male), aged 22-65 years (mean 37.8, SD 8.3). Results showed that the LOT-R has good internal consistency (Cronbach's alpha = 0.71 and item total correlation coefficients from 0.27 to 0.73, a unitary structure, and stability over a 3-months period (r = 0.66). Moreover, the Greek version of the scale exhibited good convergent validity with single-item optimism scale (r = 0.73). Principal components analysis revealed a two-factor structure representing the constructs of optimism and pessimism. The Greek life orientation test revised appears to be a valid tool in assessing dispositional optimism in Greek speaking people and is expected to facilitate the examination of optimism in Greek speaking populations.
