Real‐time versus retrospective self‐report assessment of loss‐of‐control eating in adults undergoing bariatric surgery
Authors' conclusion
Agreement between real-time and retrospective assessments of LOC eating varied by episode size and time elapsed in the year following surgery. These findings should be considered when designing assessment batteries for bariatric surgery-seeking adults and when extrapolating research findings across studies with diverging methods of real-time versus retrospective self-report assessment of LOC eating in adults undergoing bariatric surgery.
Study context
- Population
- Adults with severe obesity undergoing bariatric surgery; assessed before surgery and at 3, 6 and 12 months after
- Exposure
- Real-time ecological momentary assessment (EMA) vs retrospective Eating Disorder Examination-Questionnaire (EDE-Q) self-report of loss-of-control (LOC) eating
- Outcome
- Agreement of EDE-Q and EMA reports of subjectively and objectively large LOC episodes
- Follow-up
- Before surgery and 3, 6, 12 months after
Main finding
As reported in the abstract
- Subjectively large LOC episodes reported more frequently via EMA than EDE-Q across time points; differences not significant
- all p > 0.05
- Objectively large LOC episodes reported more frequently via EDE-Q than EMA; significant at 6 months post surgery only
- p = 0.03
Observational data: associations, not effects.
