title: Further evidence for the fifth higher trait of personality pathology: a correlation study using normal and disordered personality measures.
abstract: Studies between disordered personality and the Big-Five or the Alternative Five-Factor model of normal personality have consistently shown four higher traits. The fifth higher trait, relating to Openness to Experience or Impulsive Sensation Seeking was less supported. The culture-free Nonverbal Personality Questionnaire (NPQ) might help us to characterise the fifth higher trait. We therefore tried the Dimensional Assessment of Personality Pathology (DAPP), the NEO-Personality Inventory-Revised (NEO-PI-R), the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) and the NPQ in 253 healthy participants. Our results yielded five factors, four of which resembled the previous ones. The fifth one, namely Peculiarity Seeking, was defined by NPQ and NEO-PI-R Openness to Experience, ZKPQ Impulsive Sensation Seeking and DAPP Stimulus Seeking. Whether the fifth factor is linked to the schizotypal personality disorder as proposed remains unanswered.
