Examining Within‐Session and Between‐Session Change in Exposure‐Meal‐Related Distress During Intensive Outpatient Treatment for Eating Disorders

= 13.67(10.27) weeks. Results from multilevel models suggested significant between-session decreases in SUDS; no significant changes in within-session SUDS occurred over the course of treatment. Models examining associations between average self-reported eating disorder symptoms and global functioning and SUDS trajectories indicated that individuals with higher global functioning reported slightly lower within-session decreases in SUDS compared with those with lower global functioning. Overall, results provide an initial descriptive examination of habituation processes associated with the use of meal-based exposures for EDs and contribute to a growing body of evidence suggesting benefits of adapting exposure-based intervention approaches for EDs.
