Profiles in Criminal Psychopathology: A Multiple Case Report Study of the p Factor

(1) Background: The one general psychopathology (p Factor) theory asserts that a superordinate dimensional construct encompasses underlying forms of psychopathology, but the theory has limited empirical linkages to criminology. (2) Methods: We utilized case reports from 12 male offenders selected from a federal jurisdiction in the central United States who were in the 99th percentile on a composite indicator of psychopathology to advance a qualitative study of the p Factor. (3) Results: Clients experienced frequent and often pathological traumatic experiences and exhibited exceedingly early onset of conduct problems usually during the preschool period. Their criminal careers were overwhelmingly versatile and contained numerous offense types, had extensive justice system contacts, and exhibited remarkable deficits in global functioning. Most clients spent the majority of their life in local, state, or federal confinement. Consistent with the theory, clients experienced a generalized psychopathology disposition that had undercurrents of externalizing, internalizing, psychotic, paraphilic, and homicidal features. (4) Conclusions: A qualitative understanding of the p Factor and its contribution to offending behaviors among correctional clients complements the statistical approach to developmental psychopathology.
