American Psychologist (Sep 17, 2018). DOI:10.1037/amp0000365 Although the field of psychotherapy has been in existence for well over a century, it nonetheless continues to be preparadigmatic, lacking a consensus or scientific core. Instead, it is characterized by a large and increasing number of different schools of thought. In addition to the varying ways in which psychotherapy has been conceptualized, there also exists a long-standing gap between psychotherapy research and how it is conducted in actual clinical practice. Finally, there also exists a tendency to place great emphasis on what is new, often rediscovering or reinventing past contributions. This article describes each of these impediments to obtaining consensus and offers some suggestions for what might be done to address them.
