Exposure therapy is a central part of cognitive behavior therapy (CBT) for eating disorders, but is underused in routine clinical practice, at least partly because clinicians often hold very negative views about this technique. Although uncontrolled cohort studies suggest that teaching clinicians to use exposure improves their attitudes, there is a need for more robust empirical designs. This study uses a nonrandomized controlled design to test whether teaching on exposure improves clinicians' attitudes to its use, and whether clinician characteristics influence such change.
