The relationship between the five-factor model and DSM personality disorder in a sample of child molesters

Abstract

The study explored the associations between the five-factor model (FFM) of personality and DSM-IV personality disorders (PDs) in a sample of child molesters. The sample displayed high rates of PD with 21 (48%) meeting the criteria for at least one PD. Correlations showed that PD were most strongly associated with the NEO domains of Neuroticism and Agreeableness. Comparison between non-PD and PD offenders revealed that individuals with PD reported higher levels of Neuroticism and lower levels of Agreeableness. Examination of the facet scores within these domains showed that offenders with PD reported higher levels of Anger–hostility, Impulsivity and Vulnerability, and lower levels of Trust, Straightforwardness and Compliance. Results suggest that the FFM can be used to differentiate PD from the general population, however, cannot differentiate specific PDs. The implications of these findings are discussed further.
