Description

Historically, personality disorders have been conceptualized as qualitatively distinct clinical syndromes, based on operational criteria. Consistent with this model, ten distinct set personality disorder criteria are outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (American Psychiatric Association, 2013). However, debate persists about the clinical utility of this categorical model, with many (Krueger, et al.) researchers supporting a dimensional model that focuses on pathological levels of normative personality traits. A recent exploratory factor analysis (De Fruyt et al., 2013) of the NEO Personality Inventory-3 (NEO-PI-3; Costa & McCrae, 2010) and The Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012), suggests that normative and pathological personality traits may fall under the same common set of domains: negative affectivity-neuroticism, extraversion-detachment, openness-psychoticism, antagonism-agreeableness, and conscientious-disinhibition. However, a confirmatory factor analysis (CFA) of this model has yet to be conducted. The purpose of this study is to further explore the relationship between normative and pathological personality traits and to test the De Fruyt et al. model by conducting a conjoint CFA of the NEO-PI-3 and PID-5. It is hypothesized that the PID-5 and NEO-PI-3 share the same underlying factor structure. Using mPlus, the model will be tested in separate samples of 300 undergraduate students at a private Midwestern university and 200 adults (> 18 years of age) from the surrounding Dayton community. Understanding the relationship between these two measures is important, as they are consistently used to diagnose and aid in treatment of individuals with personality disorders.
