Predicting personality pathology among adult patients with substance use disorders: effects of childhood maltreatment.
The purpose of this study was to examine predictive relationships between types of childhood maltreatment and personality disorders in a substance-abusing population. Three hundred thirty-nine drug- or alcohol-dependent patients completed a reliable and valid retrospective measure of childhood trauma, the CTQ, and a self-report inventory that assesses the entire range of DSM-III-R personality disorders, the PDQ-R. As a preliminary step, factor analyses were used to group personality disorders into the three DSM-III-R Axis II clusters (Clusters A, B, and C), although some diagnostic subclusters were also found. Structural equation modeling analyses revealed several significant paths between types of maltreatment and personality disorder clusters (and subclusters). Physical abuse and physical neglect were related to a subcluster of "psychopathic" personality disorders consisting of childhood and adult antisocial personality traits and sadistic traits. Emotional abuse emerged as a broad risk factor for personality disorders in Clusters A, B, and C. Emotional neglect was related to the traits of schizoid personality disorder, which formed its own subcluster. Finally, sexual abuse, which had been expected to predict borderline personality disorder traits, was unrelated to any personality disorder cluster. These findings support the view that child maltreatment contributes to the high prevalence of co-morbid personality disorders in addicted populations.
