Predictors of treatment outcome in a residential program for binge-eating spectrum disorders.

Higher-level-of-care eating disorder (ED) treatment programs are often designed specifically for individuals with restrictive EDs, and those with binge-eating spectrum disorders (BESD) have different needs. The present study sought to understand predictors of outcome in a residential treatment program designed specifically for BESD. Ninety-nine participants (81% female, 80% White, Mage = 34) admitted to a residential program designed specifically for BESD completed assessments at admission, discharge, 6-month follow-up, and 12-month follow-up. We examined ED-related and comorbid symptom predictors of binge eating severity at discharge and follow-up. In multivariate regression models, cognitive restraint, depression, anxiety, and trauma symptoms significantly predicted binge eating severity at discharge, but at 12-month follow-up, only depression and trauma symptoms remained significant predictors. Individuals with lower cognitive restraint and comorbid symptoms may benefit more from this type of treatment. Further tailoring BESD residential treatment to provide additional skills for managing cognitive restraint and comorbid symptoms may be warranted.
