In their special section of this issue entitled " Principles of Therapeutic Change: A Task Force on Participants, Relationships, and Techniques Factors," Castonguay and Beutler (this issue) summarize the efforts of an expertly planned and implemented task force meant to nudge the field further along the evolutionary path towards evidence-based practice. Although they take little credit for the undertaking, Castonguay and Beutler crafted a working group that would build upon the individual efforts of previous groups (Division 12 Empirically-Supported Treatments Task Force, Division 29 Empirically-Supported Therapeutic Relationships Task Force) and created a Gestalt that was more than the sum of its individual parts. Indeed, one of the geniuses of the Principles of Therapeutic Change Task Force is that it pushes the field to consider potentially therapeutic factors interdependently rather than independently. In creating this task force Beutler and Castonguay brought together scholars who had diverse theoretical views but who were nonetheless committed to work together toward a common goal of moving beyond their individual stances (and for very little compensation)! In a field that often seems more fractious and divided than unified, this effort was a breath of fresh air. The simple act of putting together such a task force required uncommon breadth of knowledge of the field, as well as close familiarity with the players in that field. It is particularly delightful to be able to publish a special section with Larry Beutler as one of the guest editors because he was so recently the Editor-in-Chief of this journal. Hardly resting on his laurels, Larry has continued to ask psychotherapy researchers to "go beyond," and this is just one small example of how he has influenced the progress of psychotherapy research and theory. Castonguay and Beutler are to be commended on a task force well done, with a succinct summary published in this issue and an extensive rendering in their recent book (Castonguay & Beutler, 2006b).
