Abstract

This study investigated effects of body image interpretation bias modification training on body dissatisfaction and eating disorder symptoms. Female participants in their 20s with a high level of body dissatisfaction were selected and randomly assigned to a training group(n=20), and a control group(n=19). The training group received training and feedback on body image interpretation while the control group performed an active placebo program. Participants received four online-sessions over two weeks. Body image interpretation bias, body dissatisfaction, and abnormal eating behavior were measured at baseline, after two sessions, post-training, and at follow-up. And Eating disorder symptoms were measured at baseline, post-training, and follow-up. Results from RM-ANOVA indicated that the training group had significantly increased positive interpretation bias, and decreased negative interpretation bias, levels of body dissatisfaction and abnormal eating behavior compared to the control group. Bonferroni results showed that the effect of training on positive interpretation bias and body dissatisfaction appeared in both two sessions. Such effect was maintained until follow-up. The effect of training on abnormal eating behavior began to appear during the follow-up. In the case of eating disorder symptoms, the interaction between the time of measurement and groups was not significant. These findings suggest that body image interpretation bias modification training is likely to be effective in reducing negative interpretation bias, body dissatisfaction, and abnormal eating behavior. It is also effective in increasing positive interpretation bias.
