Can evaluative pairings of others’ bodies improve body dissatisfaction indirectly? A randomized-controlled online study with adult women

Objective Body dissatisfaction is an important risk factor for developing eating disorders. This study investigated whether pairing images of normatively “healthy” weight bodies of women with positive stimuli, and images of bodies outside the healthy range (e.g., underweight) with neutral stimuli, could improve body dissatisfaction. Methods We compared behavioral and rating data from 121 adult women who participated in an online study and were randomly assigned to an intervention condition (in which healthy body mass predicted positive stimuli) or a control condition (with no contingency between body mass and stimulus valence). Results Behavioral data showed that women in the intervention condition, compared to the control condition, learned to associate healthy bodies with positive valence. Having learned to associate healthy bodies with positive valence, in turn, predicted reductions in body dissatisfaction. The intervention and control conditions were not directly associated with changes in body dissatisfaction. Conclusion Learning to associate healthy bodies with any positive stimuli could be a relevant mechanism for understanding and predicting improvements in women's body dissatisfaction. Further research is required regarding the impact of contingency learning on the evaluation of other bodies, and the selection of other bodies for body-related social comparison processes.
