Norcross J C, Koocher G P, Garofalo A: Discredited Psychological Treatments and Tests: A Delphi Poll.
Professional Psychology: Research and Practice 37(5): 515-522, 2006.
Abstract: In the context of intense interest in evidence-based practice (EBP), the authors sought to establish consensus on discredited psychological treatments and assessments using Delphi methodology. A panel of 101 experts participated in a 2-stage survey, reporting familiarity with 59 treatments and 30 assessment techniques and rating these on a continuum from not at all discredited to certainly discredited. The authors report their composite findings as well as significant differences that occurred as a function of the experts’ gender and theoretical orientation. The results should be interpreted carefully and humbly, but they do offer a cogent first step in consensually identifying a continuum of discredited procedures in modern mental health practice.
