Abstract
OBJECTIVE: This study investigated the impact of COVID-19 on young women's disordered eating and their responses to online interventions to reduce disordered eating. METHOD: University students at risk of developing an eating disorder (N = 100) were randomly assigned to either receiving an online intervention to reduce disordered eating or not. Forty-one participants entered the study from September 2019 to March 2020 (pre-COVID) and 59 after physical distancing was introduced due to COVID pandemic (during COVID). Online assessments were conducted at baseline and 1-week follow up. RESULTS: There was a significant increase in weight concerns, disordered eating, and negative affect among participants entering the trial during COVID compared to pre-COVID. The increases in the first two variables remained when adjusting for baseline negative affect. No significant interactions between time, condition and COVID status were observed. DISCUSSION: Young women experienced increased levels of disordered eating after the onset of COVID. While no interactions with COVID were detected, changes to within-group effect sizes for disordered eating more than doubled for both online interventions and assessment from pre-COVID to during COVID, suggesting any attention to issues related to disordered eating in the context of reduced social contact may be beneficial.
