Psychometric properties of the Spanish version of the Life Orientation Test Revised (LOT-R) in a sample of people wit

The aim of this paper was to measure the psychometric properties of the Life Orientation Test (LOT-R) in a sample of people with fibromyalgia. To gather an adequate sample, we contacted people with a fibromyalgia diagnosis via the Internet (n =154). We measured reliability using Cronbach s alfa, explanatory and confirmatory factor analyses and correlation among optimism, stress and negative affect. Results showed adequate psychometric properties of the LOT-R; a Cronbach s alfa of .81, evidence of a second order-factor model with an adequate goodness-of-fit, and negative and significant correlations with stress and negative affect.
