Development and validation of a life satisfaction scale for Chinese elders.

This study reports the development and validation of a culturally sensitive, domain-specific measure of life satisfaction for Chinese Elders--The Life Satisfaction Scale--Chinese (LSS-C). The LSS-C was administered to 1,502 randomly-selected older Chinese persons in three newly developed towns in Mainland China. Confirmatory factor analysis supported a conceptually meaningful two-factor model-one of instrumental needs of daily life and one of social and relational needs. Criterion-related validity was satisfactory when positively correlated with a single-item global life satisfaction measure and the Life Satisfaction Index A, and negatively correlated with the Center for Epidemiological Studies Depression Scale. The reliability of the eight-item scale was satisfactory, with the internal consistency coefficient equal to .78 and the split half coefficient equal to .81. LSS-C was direct and easy to administer, and it is recommended for use on Chinese elders.
