Tokyo psychiatrist, Dr. Douglas Berger, comments on “The Interplay of Mood Disorders and Eating Disorders” by Blair Uniacke, MD and Allegra Broft, MD, May 26, 2016 issue of the Psychiatric Times:
The authors state that CBT is a “well established” evidence-based treatment” for mood disorders, however, there has never been a single-(=which is defined as patient blind) or double-blind, and thus no blind-placebo, controlled clinical trial of CBT for any indication.
This is one reference, however, regardless of this study no CBT trial has ever had more than masked assessment which just records the subjective reports of the subject-treater system, bias can not be filtered by an unblinded study, and conclusive efficacy statements should be tempered:
