Impact of exposure to counterstereotypic causality of obesity on beliefs about weight controllability and obesity bias

ABSTRACT

Individuals with obesity often report experiencing prejudice and discrimination due to their weight. Past research on obesity bias reduction strategies have yielded mixed results. The present study investigated the effectiveness of manipulating information about weight controllability in reducing obesity bias. Participants (N = 350) were randomly assigned into one of three conditions: counterstereotypic, stereotypic, or control. Each condition consisted of four short vignettes. The counterstereotypic condition provided an uncontrollable explanation of obesity (e.g., genetics) in each vignette describing a person with obesity, while the stereotypic condition emphasized lifestyle choices as the main cause of obesity. The control condition included a vignette in which weight was not addressed. Participants completed questionnaires about weight controllability and obesity bias pre- and post-exposure. There was a significant interaction between time and condition on beliefs about weight controllability and obesity bias. Participants in the counterstereotypic condition increased in belief about the uncontrollability of weight and decreased in obesity bias, while participants in the stereotypic condition decreased in belief about the uncontrollability of weight and increased in obesity bias. Obesity bias reduction strategies that utilize information about weight controllability can be effective. However, perpetuating stereotypic causes of obesity can worsen the problem.
