Three separate and distinct literatures exist investigating general factors of psychopathology (p factor), personality (general factor of personality, GFP), and personality disorder (g-PD). Surprisingly, there has been little to no investigation regarding the convergence of these three distinct general factors. In the present investigation, two studies were conducted examining the convergence of the p factor, GFP, and g-PD. In Study 1, a combined model extracting all three factors from self-report data simultaneously found high convergence. The findings for the g-PD and GFP were replicated in Study 2 using multimethod data, wherein the GFP and the g-PD were extracted from a community sample of 1,630 older adults and correlated with an index of maladaptivity. The present findings support the position that general factors of psychopathology, personality disorder, and personality are likely to entail a common individual differences continuum, which may impact on how these general factors are to be understood.

This study proposes a psychometric approach to assess the General Factor of Personality (GFP) to explain the whole personality. This approach defends the existence of one basic factor that represents the overall personality. The General Factor of Personality Questionnaire (GFPQ) is presented to measure the basic, combined trait of the complete personality. The questionnaire includes 20 items and is constituted by two scales with 10 items each one: the Extraversion Scale (ES) and the Introversion Scale (IS). The GFPQ shows adequate internal consistency and construct validity, while the relationships with the personality factors of other models and with psychopathology are as expected. It correlates positively and significantly with Extraversion (E) and Psychoticism (P), and negatively with Neuroticism (N) of Eysenck's EPQ (Eysenck Personality Questionnaire); it correlates positively and significantly with the Sensation Seeking Scaled (SSS) of Zuckerman, and is inside the expected direction with Sensitivity to Reward (SR) and Sensitivity to Punishment (SP) of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), which represent the approach and avoidance trends of behavior, respectively. It not only relates negatively with the personality disorders of the anxiety spectrum, but also with the emotional disorders in relation to anxiety and depression, and it relates positively with the antisocial personality disorder.
