“…However, literature on the relation between pathological personality dimensions and psychosis is sparse, as is literature comparing patients with psychotic disorders with clinical controls. Regarding the first, two studies with the Personality Psychopathology Five model by Harkness and McNulty (1994) have found its pathological fifth factor Psychoticism to discriminate between psychometrically identified schizotypic and nonschizotypic college students (Hunter et al, 2014), as well as between patients diagnosed with schizophrenia versus healthy control subjects (Bolinskey et al, 2001; Carter, Parnas, Cannon, Schulsinger, & Mednick, 1999). Regarding the second, two studies have compared patients with psychotic conditions with patients diagnosed with other psychiatric disorders and found, most interestingly, FFM Neuroticism to be lower in the psychotic group (Berenbaum & Fujita, 1994; Uliaszek, Al-Dajani, & Bagby, 2015).…”
