A survey of the professional literature found several books and articles that have listed or described psychotherapies that are unsupported, probably ineffective, and/or potentially harmful. This information is presented in Table 1. This is not a complete list; only the most authoritative sources in the psychological literature have been included here. Readers should consult the authors of the lists for more information and clarification regarding the reasons for why the authors listed specific treatments. It should be noted that a few therapies, such as EMDR, have been described as poorly supported by some writers and as well supported by others. Citations for sources are given beginning with the most recent.
