There is considerable interest in the study of the general factors of personality disorder (g-PD), psychopathology (p factor), and personality (GFP). One prominent interpretation of the g-PD is that it is defined by the self-interpersonal impairments of Criterion A of the DSM-5 Section III. However, no study has directly tested this hypothesis as no prior g-PD study has included a measure of Criterion A. The current study provides a direct test of this hypothesis, along with comparing g-PD with the general factors of psychopathology and personality. Also extracted was a common general factor across all three domains. Suggested herein is that the g-PD, the p factor, and the GFP reflect the impairments (e.g., social and occupational dysfunction) that are secondary to the traits and disorders rather than the traits and/or disorders themselves.
