Validation of Self-Image of Aging Scale for Chinese elders

Int J Aging Hum Dev. 2012;74(1):67-86. doi: 10.2190/AG.74.1.d.

Abstract

Researchers are increasingly interested in the "image of aging" concept. Models on the image of aging abound, but few have rigorously tested measures that are culturally sensitive and domain-specific. This study first translates Levy et al.'s (2004) Image of Aging Scale into the Chinese language and revises it into the Chinese Version of the Self-Image of Aging Scale (SIAS-C). Based on the results of a survey of 445 elderly people in Wuhan-China, it then reports the factorial structure of SIAS-C and some of its psychometric properties. Confirmatory factor analysis (CFA) supports a conceptually meaningful five-factor model, as suggested in an exploratory factor analysis (EFA). The 14-item SIAS-C vindicates an acceptable level of internal consistency and test-retest reliability. Its criteria-referenced validity is demonstrated by its correlation with several criteria in expected directions. In conclusion, the SIAS-C is a psychometrically sound instrument which is recommended for use among Chinese older people.
