Expand Your Horizon: Testing a Brief Writing Intervention Focused on Body Functionality Among Adolescent Girls With an Eating Disorder

Method

Fifty-eight adolescent girls with an eating disorder were randomly assigned to the EYH condition or an active control condition. Different aspects of positive and negative body images were assessed before and after the intervention. Results: Participants in the experimental condition showed higher scores than the control condition on positive body image after the writing exercise, but no effects on negative body image were found.

Exploratory analyses showed that improvements in the positive body image remained stable 15–30 min after the writing exercise. Discussion: These outcomes suggest that writing about body functionality leads to direct increases in positive body image but not to decreases in negative body image. An important step for future studies would be to test the full three-session version of EYH and investigate its effects over the longer term.

This could help to determine the robustness of the present findings and the potential of EYH as a complementary intervention to existing treatments.d text (2025).
