Mapping the Personality Assessment Inventory (PAI) Onto the Hitop Model of Psychopathology: Confirmatory Factor Analysis Using Treatment Seeking Veterans at Veteran Affairs

This study expands literature connecting the HiTOP model to commonly used diagnostic measures. Confirmatory Factor Analysis of the PAI’s non-overlapping substantive scales in Veterans builds on prior work conducted with an active-duty sample. Following higher-order corrections, a well-fitted 3-super factor model was observed consistent with contemporary models of psychopathology.
