The Society for Psychotherapy Research (SPR) is devoted to the development and dissemination of research, as well as the integration of empirical, theoretical, and clinical knowledge in psychotherapy. A highlight of the SPR annual meeting is the presidential address, wherein the president delivers what many view as the most important presentation of their career. In Visions of Psychotherapy , Bernhard Strauss, Jacques Barber, and Louis Castonguay, three recent past presidents, compile the preceding 20 presidential addresses from SPR into a single volume. Then, the living presidents (19 of the 20) comment on how the visions they described in their addresses have developed over time.
