AUTHOR=Berg Henrik TITLE=Why Only Efficiency, and Not Efficacy, Matters in Psychotherapy Practice JOURNAL=Frontiers in Psychology VOLUME=Volume 12 - 2021 YEAR=2021 URL=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.603211 DOI=10.3389/fpsyg.2021.603211 ISSN=1664-1078 ABSTRACT=Evidence-based practice in psychology consists of two quality parameters. One of these parameters is efficacy and the other is efficiency. In this paper, it is argued that the only relevant parameter for determining quality in clinical care is efficiency. It is argued that emphasising efficacy in psychotherapy practice is symptomatic of a scientocentric ideal in evidence-based practice in psychology. The proper understanding and use of scientific findings depend on leaving this scientocentric ideal. Crucially, efficiency must be related to the ethical aims integrated in a practice like psychotherapy.
