摘要:In the development of psychotherapy, the debate between opting for a specific model as opposed to systems integration has been a growing controversy. In addition, questions have been raised with regards to the consistency of integration approaches, the benchmark for choice of integration approach and the proficiency of practitioners. This article examines the reasons for integration using a systematic review to evaluate the triumphs made since the inception of psychotherapy integration. The authors’ advocates for Miller, Duncan, and Hubble’s in 2004 suggest practice-based evidence approach one of the appropriate innovative way of improving client retention and outcome. To us, this approach will enable the clinician have a better stand in therapy as scientist-practitioners.
