Examining the Factor Structure and Psychometric Properties of the Chinese Version of the Life Orientation Test in Older Chinese Immigrants.

The current study examined the factor structure and psychometric properties of the Chinese version of the Revised Life Orientation Test (CLOT-R) in a sample of 342 community-dwelling older Chinese immigrants in Canada (mean age = 71.99,  = 5.62; 58.5% female). Confirmatory factor analysis demonstrated that the CLOT-R yields a two-factor model with one item cross-loading on two latent constructs of optimism and pessimism. Analysis further revealed poor internal consistency and convergent validity. Evidence for discriminant and convergent validity was found between optimism and perceived stress, as well as optimism and quality of life. Compared with the factor structure reported in previous Chinese-speaking samples, the modified two-factor structure found in the current group of older Chinese immigrants could be attributed to the heterogeneity of the sample and possible configural variance across culture and age. Overall, the current findings suggest that the CLOT-R may not be a reliable and valid measure to assess dispositional optimism and pessimism among older Chinese immigrants. Theoretical implications and suggestions for further scale development and research is discussed.
