Objective
Brief cognitive‐behavioral therapy for non‐underweight eating disorders (CBT‐T) has been shown to be clinically useful in non‐underweight samples, when delivered one‐to‐one. This pilot study assessed the acceptance, compliance and feasibility levels of a group version of CBT‐T, which has the potential to enhance patient access.
Method
A group CBT‐T protocol was developed and piloted in two therapy groups (N = 8). Eating disorder attitudes and behaviors, depression and anxiety were assessed at the beginning and end of treatment.
Results
A third of all patients approached accepted the offer of group CBT‐T, and entered treatment. Among that group of treatment starters, none were lost to treatment. The therapy was feasible in practical terms, including online delivery. Finally, mean scores on measures suggested improvement in clinical profiles.
Discussion
This pilot study demonstrated that a group CBT‐T is a feasible intervention for non‐underweight eating disorders in adults, with low acceptance but high compliance. Group CBT‐T has the potential to reduce demand on services and in turn increase availability of treatment to those with eating disorders.
Public Significance
The present research contributes to the treatment of non‐underweight adults with eating disorders. Group CBT‐T was shown to be feasible in this pilot study. It was associated with low acceptance but strong compliance. If supported by further research, group CBT‐T has the potential to reduce waitlists, ensure throughput in services, and ultimately improve the lives of many who are affected by eating disorders.
