Ken Critchfield, Ph.D. is an adjunct Assistant Professor of Psychology and Psychiatry (University of Utah). Dr. Critchfield is the co-director of the Interpersonal Reconstructive Therapy (IRT) clinic at the University Neuropsychiatric Institute. Additionally, he was a task force member (2003-2006), for APA’s Div. 12, Task Force on Empirically Supported Principles of Therapeutic Change.
Dr. Critchfield’s research and clinical interests focus on the intersection of relational science, personality, and attachment-based perspectives on development, psychopathology, and change in psychotherapy. For the past several years he has worked closely with Dr. Lorna Smith Benjamin to operationalize and test the efficacy of Interpersonal Reconstructive Therapy (IRT) as it is applied to severe and chronic psychiatric problems involving comorbid Axis II diagnoses. IRT is an integrative approach in the sense that it optimizes treatment (both relationship and technique factors) based on a case formulation that specifies treatment goals and optimal strategies for individual patients. IRT is thus both theoretically-grounded and technically integrative, providing a rational basis for choice of specific interventions at specific moments.
Consistent with the outlook of the UPP, techniques used in IRT may be culled from any “school” of therapy may be implemented, so long as they fit the particular patient’s case formulation, treatment goals, and the moment in therapy.
The Unified Psychotherapy Project seeks to document and organize strategies, procedures, and specific interventions developed across schools of psychotherapy so that clinicians of all stripes can make similar selections from among the catalog of “what works” based on consideration of patient needs, goals, and capacities.
In addition to clinic-based service, research, and teaching, Dr. Critchfield maintains an active private practice applying IRT to a wide range of clinical problems. He frequently consults on issues of methodology, design, and analysis for projects involving the interface between interpersonal measurement (especially moment-by-moment interactional process using the Structural Analysis of Social Behavior), personality, and psychopathology.
