About The 3PL Lab
The Personality, Psychopathology, & Psychometrics Lab (The 3PL) conducts research related to the classification, description, and measurement of personality and psychopathology. We study dimensional models of personality and psychopathology, applied and basic psychological assessment, modern psychometric models and methods (e.g., item response theory applications and computerized adaptive testing). Our primary targets for research include structural models of personality, personality pathology, depression, and anxiety disorders.
We also are interested in the translation of the above models and methods to applied clinical practice, which is an underdeveloped area of the literature.
Trevor Williams, a senior doctoral student in the lab, has been awarded the Bugelski Dissertation Award from the Department of Psychology. Nice job, Trevor!!
The 3PL was excited to host the national conferences for the Society for Research in Psychopathology (SRP) and the Hierarchical Taxonomy of Psychopathology (HiTOP) consortium, both in Buffalo, in September 2019.
The 3PL was fortunate to welcome Leah Emery to the lab in September as a new doctoral student. Leah came to us after earning her Master’s degree from Wake Forest University.
Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD) Project
An NIMH-funded project to develop an integrative trait model of personality disorder and a suite of efficient measures (self-report and interview) to measure those traits.
Hierarchical Taxonomy of Psychopathology (HiTOP)
The 3PL is part of an international consortium of labs and investigators working to develop an evidence-based, dimensional psychopathology classification system. The lab is particularly involved in efforts to build HiTOP measures and to translate HiTOP into applied clinical practice.
Diagnostic Assessment Practices (DAP) Project
We currently are studying the current assessment and classification practices of mental health practitioners and the impediments to adoption of moderns methods in applied clinical practice.
Studies of the phenotypic structure of personality, personality disorder, depressive and anxious symptomatology, and posttraumatic stress disorder.
