Clinical practice guidelines in clinical psychology and psychotherapy.

Evidence-based clinical practice guidelines have proliferated over the past two decades. Few are limited to psychological therapies or are targeted at clinical psychologists and psychotherapists – the UK guideline Treatment Choice in Psychotherapy and Counselling is a major exception. However, psychological therapies will increasingly be considered alongside medical treatments in diagnosis-specific guidelines. There has been interest and debate about the place of guidelines in the psychological therapies, with views ranging from scepticism to enthusiasm. This paper defines clinical practice guidelines, describes major guideline programmes internationally, examines guidelines of specific interest to psychologists and psychotherapists, explores issues in their implementation, reviews evidence for their effectiveness in changing practice and improving therapy outcomes and draws out implications for practice. Guidelines are only one aspect of informing psychologists and psychotherapists about best practice. They need to be supplemented by other clinical support methods and with methods of monitoring what is actually done in practice. Copyright © 2003 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
