How COVID-19 lockdown measures could impact patients with bulimia nervosa: Exploratory results from an ongoing experience sampling method study

Abstract

Objective

The impact of COVID-19 lockdown measures on patients with an eating disorder remains unclear, but preliminary results indicate that some patients could be more vulnerable to experience an increase in eating disorder pathology than others. To provide possible directions for future research, this report explored the impact of the Belgian COVID-19 lockdown measures on patients with bulimia nervosa (BN).

Methods

The data of 15 female patients with BN from an ongoing experience sampling method study were analyzed. Mixed effects models compared surroundings, social context, negative affect (NA), positive affect (PA) and binge eating before and after the implementation of the lockdown measures.

Results

After the implementation of the lockdown measures, significant changes in surroundings and social context were found as well as an increase in NA and decrease in PA. Patients who experienced a higher binge eating frequency during the lockdown also experienced a stronger change in NA and PA.

Conclusions

Future research should also look at changes in surroundings, social context, affect and how these interact with factors such as personality traits and coping styles when investigating why some patients are more susceptible to the negative effects of lockdown measures than others.
