Psychology should list empirically supported principles of change (ESPs) and not credential trademarked therapies or other treatment packages.

Current systems for listing empirically supported therapies (ESTs) provide recognition to treatment packages, many of them proprietary and trademarked, without regard to the principles of change believed to account for their effectiveness. Our position is that any authoritative body representing the science and profession of psychology should work solely toward the identification of empirically supported principles of change (ESPs). As challenging as it is to take this approach, a system that lists ESPs will keep a focus on issues central to the science and practice of psychology while also insulating the profession from undue entrepreneurial influences.
