Validation of the work-related age-based stereotypes (WAS) scale

Abstract

The purpose of this paper is to focus on developing and validating a multidimensional measure of work-related age-based stereotypes (WAS) scale. Based upon a review of the literature, a three-dimensional stereotype content model including both negative (incompetence, inadaptability) and positive (warmth) stereotypes of older workers was created. Construct, convergent, discriminant, and criterion-related validity for the WAS scale were examined across three independent samples constituting both lab-based experimental studies and a field-based survey (total n=1,245). Across all samples, the WAS evidenced good construct, convergent, discriminant, and criterion-related validity. As evidenced by a review of the literature, the WAS is unique in that it measures both negative and positive stereotypes of older workers. Implications for research are discussed.
