Alliance, technique, both, or more? Clinicians' views on what works in cognitive-behavioral therapy for eating disorders.

Clinicians overestimate the value of both the alliance and therapy techniques in explaining treatment outcomes in CBT for eating disorders. Their beliefs about the strength of these factors are related to their own anxiety, and to their choice of techniques. Clinicians and supervisors should attend to the evidence regarding the impact of a range of elements of therapy, and work with all of those factors to enhance outcomes.
