Dr. John L. McNulty graduated from the University of Tulsa in 1995 with a PhD in clinical psychology. Prior to returning to TU in the fall of 1999, he completed post-doctoral training at Kent State University, specializing in personality assessment. He has authored or co-authored numerous articles or book chapters, and co-authored a book with John R. Graham and Yossef S. Ben-Porath on the interpretation of the Minnesota Multiphasic Personality Inventory - 2nd Edition (MMPI-2), the most widely used personality assessment instrument in the world. Dr. McNulty received the 2003 Society for Personality Assessment Samuel J. and Anne G. Beck Award for outstanding early career research in the field of personality assessment.
In addition to personality assessment, Dr. McNulty has collaborated with Dr. Allan Harkness, also at TU, in developing a dimensional model of personality named the Personality Psychopathology Five (PSY-5). With Y.S. Ben-Porath, they developed scales to assess the model that have been included with the MMPI-2 and are routinely reported and used by clinicians.
With Dr. Allan Harkness in the Department of Psychology, and Dr. William Potter and Dr. Robert Sheaff in the Department of Chemistry, Dr. McNulty co-founded the interdisciplinary Institute for Biological and Psychological Study of Individual Differences (IPBID). As the name suggests, institute members are involved in the exciting development of fundamental theories about the nature of the behavioral systems that structure and guide adaptive behavior.
