In this episode, Xavier Bonilla has a dialogue with Allie Choate about the statistical aspects of measuring personality. They start the conversation by giving a general definition of psychopathology and p-factor. They discuss some internalizing and externalizing factors of p-factor and how it operates laterally with the g-factor of intelligence. They talk about which disorders the p-factor correlates most and how it is implicated. They provide a larger discussion around personality disorders along with the co-morbidity of personality disorders with other clinical disorders. Allie shares findings from her research with borderline personality disorder and psychopathy and the surrounding literature on these topics. They discuss the bifactor model/factor analyses that are used to understanding psychopathology research and many other topics. 
Allie Choate is a PhD candidate in clinical psychology with her research focused on personality pathology and quantitative methods to understand psychological phenomena. Twitter: @alliemchoate
