Objective: Findings show virtual therapy (conducted using internet-based videoconferencing techniques) to be a viable alternative to in-person therapy for a variety of mental-health problems. COVID-19 social-distancing imperatives required us to substitute virtual interventions for in-person sessions routinely offered in our outpatient eating disorder (ED) program-and afforded us an opportunity to compare the two treatment formats for clinical efficacy.

Methods: Using self-report assessments, we compared outcomes in a historical sample of 49 adults with heterogeneous EDs (treated in-person over 10-14 weeks in individual and group therapies) to those of 76 patients receiving comparable virtual treatments, at distance, during the COVID-19 outbreak. Linear mixed models were used to study symptom changes over time and to test for differential effects of treatment modality.

Results: Participants in both groups showed similar improvements on eating symptoms, levels of weight gain (in individuals in whom gain was indicated), and satisfaction with services.

Discussion: Our results suggest that short-term clinical outcomes with virtual and in-person ED therapies are comparable, and point to potentials of virtual therapy for situations in which geographical distance or other barriers impede physical access to trained therapists or specialized treatments.
