Discredited Assessment and Treatment Methods Used with Children and Adolescents: A Delphi Poll.

In the context of intense interest in identifying what works in mental health, we sought to establish a consensus on what doesnot work-discredited psychological assessments and treatments used with children and adolescents. Applying a Delphi methodology, we engaged a panel of 139 experts to participate in a two-stage survey. Participants reported their familiarity with 67 treatments and 35 assessment techniques and rated each on a continuum from not at all discredited to certainly discredited.
