Louis G. Castonguay, Ph.D.Bio- sketchAfter his undergraduate studies in Psychology at the University of Sherbrooke and a Masters degree in Counseling Psychology at the University of Montreal, he completed his doctorate in Clinical Psychology at S.U.N.Y. Stony Brook, a clinical internship at U.C. Berkeley, and a Post-doctorate at Stanford University. He is currently Professor at the Department of Psychology at The Pennsylvania State University, where he also served as the Associate Director for the Clinical Program and the Director of the Graduate Studies. His research focuses on the process of change in different forms of psychotherapy (cognitive-behavioral, psychodynamic, and integrative), especially for the treatment of anxiety disorders and depression. Within this context, he has investigated several factors related to the client (e.g., emotional experience), therapist (e.g., focus of intervention) and the therapeutic relationship (e.g., working alliance). He is also involved in the investigation of the efficacy of new integrative treatments for generalized anxiety disorder and depression. With students and colleagues, he is also conducting effectiveness research aimed at better understanding and possibly improving psychotherapy as practice in natural settings. He has more than 140 publications, including five co-edited books: On empirically based principles of change in psychotherapy (with Larry Beutler); insight in psychotherapy (with Clara Hill); corrective experiences in psychotherapy (with Clara Hill); the integration movement in psychotherapy (with Conrad Lecomte); and on the legacy of influential figures of the Society for Psychotherapy Research, SPR (with Chris Muran, Lynne Angus, Jeff Hayes, Nick Ladany, and Tim Anderson). Based on his dissertation research (on the process of change in cognitive therapy for depression), he won the Graduate Student Paper Competition awarded by the Division of Psychotherapy of the American Psychological Association (APA). He has also received the Early Career Contribution Award from SPR, the Jack D. Krasner Memorial Award from the APA Division of Psychotherapy, and the David Shakow Early Career Award from the APA Division of Clinical Psychology. With Thomas Borkovec and Stephen Ragusea, he has received the Pennsylvania Psychological Association Presidential Award for their work on a state-wide Practice-Research Network. He has also received three additional recognitions from the APA Division of Psychotherapy: the Distinguished Psychologist Award for his life time contributions to the field of psychotherapy, the Distinguished Contributions to Teaching and Mentoring, as well as the Distinguished Research Publications Award. He served as President of the International Society for Psychotherapy Research (SPR) and the North American Society for Psychotherapy Research (NASPR), and co-chaired (with Larry Beutler) the APA Division of Clinical Psychology and NASPR Task Force on Empirically Based Principles of Therapeutic Change. He also serves on the Steering Committee of the Society for the Exploration of Psychotherapy Integration (SEPI). Moreover, he has co-chaired (with Clara Hill) The Penn State Conferences on The Process of Change, which has regrouped prominent psychotherapy researchers interested in delineating quantitative and qualitative methods that can help us better understand how clients’ change. He chaired the Pennsylvania Psychological Association-Practice Research Network (PPA PRN), and has been chairing for several years the committee responsible for the creation and implementation of a Practice Research Network at the Psychology Clinic of the Penn State University. He has also team up with Ben Locke and Jeff Hayes in developing a Practice Research Network involving more than 150 Counseling and Psychological Centers on college campuses in the US. With David Kraus, he is also in the process of creating an international Research Practice Network, which will allow them to develop a large infrastructure for the conduct of clinically meaningful and scientifically rigorous studies on the process and outcome of psychotherapy. These are part of a number of initiatives that he has been involved in with the goal of fostering an active collaboration between researchers and clinicians. He also maintains a part-time private practice.
