Personality and Individual Differences Lab


Dr. Allan Harkness and Dr. John McNulty have developed the Personality Psychopathology Five (PSY-5) model that is similar to other models in some respects, but different in ways that are important to understanding personality dysfunction.  Scales were developed to assess the PSY-5 in adults with the Minnesota Multiphasic Personality Inventory - 2nd Edition, and in adolescents with the Minnesota Multiphasic Personality Inventory - Adolescent.

Individual differences theory is a theory of personality that focuses on distinct continua, or dimensions, along which people differ from each other. Drs. McNulty and Harknessí lab emphasizes individual differences and the interaction between personality and clinical problems.  In particular, members of the lab are interested in applying individual differences science to the design of new therapeutic approaches. 

What's  New

  • A new set of Restructured Clinical, or RC, scales have recently been developed. 
  • Research with the "RC" scales has just begun.
  • 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.
