The stigma of obesity and discrimination in performance appraisal: a theoretical model

We propose a theoretical model to study the effect of obesity stigma on performance appraisal. The model draws from the appraisal, obesity, stigmatization, and prejudice literatures to examine three sets of factors: individual factors in the appraiser(s) and the obese appraisee; factors in performance appraisal; and contextual factors. According to the model, these factors make it easier or harder for obesity stigma to affect the performance appraisal of obese employees, potentially biasing the process and resulting in discrimination. While examining the interplay of forces that facilitate or inhibit the expression of obesity stigma in the affective, cognitive, and behavioral responses of appraisers, we introduce the concept of ‘aversive weightism’. This concept enhances understanding of the tensions between the ethos of objectivity in performance appraisal and the deeply rooted, often unconscious influences of societal prejudice and stigma against obesity. We conclude with implications for research and practice.
