Welcome to the Personality, Psychopathology, & Psychometrics Lab (3PL) at the University at Buffalo


The Personality, Psychopathology, & Psychometrics Lab conducts research broadly relevant to measurement of and theory related to personality and psychopathology. More specifically, we are interested in applied and basic psychological assessment, dimensional models of personality and psychopathology, item response theory applications to personality measurement, and computerized adaptive testing.  Most recently, we have been involved in the following projects:

• Studies of higher order personality models--such as the Big Three, Big Five, and Big Seven--and their relevance to prominent models of personality and personality pathology.
• Studies of self-other agreement and assortative mating/pairing with regard to personality traits.
• Studies to understand the structural relationships among dimensions underlying depression and anxiety.
• Studies of the dimensions underlying posttraumatic stress disorder (PTSD) and their relations with anxiety and depression more generally.
• Collaborative development and validation of the Schedule for Nonadaptive and Adaptive Personality (SNAP), a trait measure of personality pathology
• Development of a computerized adaptive version of the SNAP
• Collaborative development of the Iowa Depression and Anxiety Scales (IDAS), a multi-dimensional measure of depression and anxiety.
