This study aimed to explore the relationship between the personality disorders and five factor model and their factor structures in a Filipino non-clinical sample. The participants were 828 respondents from various areas in the Philippines. 35.5 % males and 64.3% females. The average age of respondents is 20.29 (SD = 4.83). The Millon Clinical Multiaxial Inventory (MCMI-III) and the Neuroticism, Extraversion and Openness Personality Inventory – Revised (NEO-PI R) were used as assessment measures. Eight factors were extracted from a varimax principal components analysis including the 30 NEO-PI-R facets and the 14 PD scales. The results show that the five-factor model is modestly related to personality disorders as described in the DSM IV. There is a modest correspondence between personality disorder and NEO dimensions and facets. Regression analyses showed that NEO domain and facet scores explained a fifth to a third of the variance in PD dimensions. The results lend measured support to the correspondence of personality disorders and FFM theory of personality, however, the breadth of personality disorder pathology is not completely covered by the NEO. It seems then necessary to use additional clinical material, beyond the NEO, to describe personality disorder dimensions.

Scholars in personality psychology and clinicians are currently exploring the idea that the Five-Factor Model (FFM) of personality is the most functional and inclusive taxonomy for understanding problems associated with personality disorders. This study attempts to explore the relationship of personality disorders and the FFM as well as explore the factor structures of PD and FFM in Filipino non-clinical sample.
Personality disorders may be best described by three pathological characteristics (Millon, Millon, Grossman, & Meagher, 2002). The first comes from the view that personality is the psychological equivalent
