Abstract
The primary focus of this paper is an examination of the construct validity of cognitive age measurement. Through a review of cognitive age research, it is concluded that cognitive age has not been well grounded with respect to construct validity although it can basically enrich one's understanding of older people's self concepts, attitudes, and behaviors.
In this research, multitrait-multimethod matrix data consisting of 9 variables (cognitive age, ideal age, and least desired age, as measured by three methods; Staple, Semantic Differential, and Likert scales) was analyzed in the framework of hierarchically nested covariance structure models in order to test the significance of convergent and discriminant validity. A path analytic conceptualization performed well in terms of goodness-of-fit, and the findings provide strong support for construct validity of cognitive age measurement.
