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 α = .71 and item total correlation coefficients from .27 to .73, a unitary structure, and stability over a 3-months period
(r = .66). Moreover, the Greek version of the scale exhibited good convergent validity with single-item optimism scale (r = .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. 相似文献
