Does hopelessness predict treatment outcomes in adults with binge-spectrum eating disorders?

Ross M Sonnenblick et al. Eat Disord. 2024 Jul-Aug.

Abstract

Using data from 165 adult participants who enrolled in four studies of cognitive-behavioral therapy (CBT) for binge-spectrum eating disorders (EDs), this secondary analysis examined 1) whether pretreatment hopelessness predicted posttreatment eating pathology, loss-of-control (LOC) eating frequency, and purging frequency; 2) whether treatment had an indirect effect on those outcomes through change in hopelessness; and 3) whether treatment had an indirect effect on hopelessness through those ED measures. The Eating Disorder Examination was used to assess overall eating pathology, LOC frequency, and purging frequency. Hopelessness was measured with one item from the Beck Depression Inventory-II. Regression models showed that pretreatment hopelessness predicted posttreatment LOC eating frequency but not overall eating pathology or purging frequency. Single-group tests of indirect effects showed no effect of reduction in hopelessness on reduction in ED symptoms, but there was an effect of reduction in ED symptoms on reduction in hopelessness.

Overall eating pathology = pre-treatment minus post-treatment EDE Global score. Change in LOC episodes = pre-treatment minus post-treatment LOC episodes. Change in purging episodes = pre-treatment minus post-treatment purging episodes. *p < .001 (95% CI)
