Evaluating the feasibility and potential efficacy of a brief eTherapy for binge-eating disorder: A pilot study.

Abstract

For those with binge-eating disorder (BED), access to evidence-based, face-to-face treatment is often constrained by clinician availability and high treatment costs. Emerging evidence suggests online therapy (eTherapy) may navigate these barriers and reduce binge-eating symptomatology; however, less evaluation has been done in those with BED, particularly with briefer programs targeting early change. This study investigated the feasibility and potential efficacy of a brief, supported eTherapy in those with BED or subthreshold BED. Participants were 19 women with BED who completed a four-session eTherapy. This was a single-arm, pre-post intervention study, with participants completing weekly content and attending telehealth sessions. Key outcomes were assessed by the Eating Disorder Examination Questionnaire-Short (EDE-QS): objective binge episode days, loss of control over eating days, and eating disorder (ED) psychopathology via a total EDE-QS score. Generalized and linear mixed models showed significantly reduced loss of control over eating days and ED psychopathology. Program feasibility was high, with strong program adherence and a below average attrition rate. Pilot results support the feasibility and potential efficacy of a brief, behavioral-focused eTherapy program in reducing ED pathology in those with BED. Future research should further investigate findings in an adequately powered randomized controlled trial. This study suggests that a brief, behavioral-focused online therapy, guided by non-expert clinicians, can be successfully administered to those with binge-eating disorder (BED) and may be efficacious at reducing eating disorder and other related symptomatology. Brief eTherapies that are effective, accessible, and rapidly available may facilitate earlier intervention in illness and improve treatment outcomes for individuals who experience this common and distressing disorder.
