Vrabel, K. R., & Bratland-Sanda, S. (2024). Effects of inpatient treatment on compulsive exercise in adults with longstanding eating disorders: Secondary analysis from a randomized controlled trial with 12-month follow-up. International Journal of Eating Disorders, 57(2), 437-449. https://doi.org/10.1002/eat.24108Abstract
Purpose: This study aimed to examine changes in compulsive exercise among adults with eating disorders (ED) admitted for inpatient treatment in a randomized controlled trial comparing cognitive behavioral therapy (CBT) and compassion-focused therapy (CFT) and whether such changes were influenced by treatment condition, childhood trauma, or level of compulsive exercise.
Method: A total of 130 adults admitted to inpatient treatment for EDs mean (SD) age 30.9 (9.7) years, mean illness duration 14.2 (8.9) years, were randomized to receive CBT or CFT and analyzed using multilevel modeling. Assessments included Eating Disorders Examination – Interview, Compulsive Exercise Test and Childhood Trauma Questionnaire.
Results: Mean total CET score at baseline was 14.7 (4.0) with no difference between the treatment groups. A total of 63 (48.5%) had CET score ≥ 15, indicating clinical levels. There was an overall time effect on reduction in CET total and all CET subscale scores except Lack of enjoyment, and CFT provided greater reduction compared to CBT on the CET subscale Mood improvements. Patients with clinical CET score levels showed greater reduction on CET total and the subscales Avoidance, Weight, and Rigidity across time compared to persons with non-clinical CET score. Childhood trauma did not predict changes in CET total or subscale scores.
Discussion: Both CBT and CFT improve overall compulsive exercise. The greater effect of CFT than CBT on exercise as a maladaptive mood regulator calls for further research on how affective oriented psychotherapies can not only reduce compulsive exercise but also promote functional exercise among persons with EDs.
Public Significance Statement: Understanding and addressing compulsive exercise in adults with eating disorders is crucial. This study comparing cognitive-behavioral therapy and compassion-focused therapy shows both improve compulsive exercise. Importantly, compassion-focused therapy has a greater impact as an emotion-focused regulator. This emphasizes the need for further exploration into how emotion-focused therapies can reduce compulsive exercise and promote healthier, functional physical activity for individuals with eating disorders.
