Abstract

Previous studies have identified specific underlying dimensions of personality disorders with remarkable consistency. This study aimed to replicate the factor structure of personality disorders using ICD-10 dimensional scores from a sample of 366 male offenders. Factor analysis yielded three factors. Factor 1 demonstrated dissocial, paranoid, histrionic, and impulsive personality traits. Factor 2 reflected borderline, anxious, and avoidant PD symptoms. Factor 3 showed high loadings on schizoid PD traits and an inverse relation to anankastic personality. The factor structure was identical to a recent study using ICD-10 personality disorder scores and showed strong similarities to previous studies using DSM-III personality disorder dimensions. Factor 1 was substantially correlated with the psychopathy total score. Elevated scores on this factor were associated with adverse childhood experiences, early behavioural problems (conduct/hyperkinetic disorder), co-morbid substance abuse in adulthood, an earlier start of criminal career, and a higher number of sentences/offences. No risk factors or childhood antecedents could be identified for Factor 2. However, this factor was distinctively characterised by co-morbid affective and neurotic mental disorders in adulthood. Factor 3 was negatively associated with measures of cognitive functioning. The findings suggest specific pathways, courses, and outcomes of the identified personality disorder dimensions.
