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.
- A new set of Restructured Clinical, or RC, scales have recently
- 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.
