Integrating cognitive dissonance and social consensus to reduce weight stigma

Abstract

Weight stigma is pervasive and has a range of deleterious effects. Among the most promising approaches for modifying this form of stigma are cognitive dissonance and social consensus. Due to their theoretical connection, this study tested the effects of an experimental manipulation of cognitive dissonance blended with social consensus for targeting weight stigma. It also added to research investigating the effects of cognitive dissonance on weight stigma by investigating a broader range of stigma measures. Participants were university students aged 18–35 years (N = 98) who were randomly allocated to one of four experimental conditions: blended cognitive dissonance, standard cognitive dissonance, blended control or standard control. Stigma measures included the perceived characteristics of, affective reactions towards, social avoidance of, and blameworthiness attributed to a higher-weight individual, and general weight stigma. Results showed that those in the cognitive dissonance conditions reported significantly lower weight stigma than those in the non-dissonance, control conditions. Moreover, those in the blended cognitive dissonance condition with higher in-group identification reported less negative affective reactions than those with lower in-group identification. The results provide consistent support for cognitive dissonance as an approach for reducing weight stigma and some additive support for an integrated cognitive dissonance and social consensus approach.
