Schizoid personality pathology is among the most debilitating and enigmatic forms of personality pathology. Some have suggested that a potential etiological influence on schizoid pathology is trauma. Thus far, research on the association between trauma and schizoid pathology has focused primarily on type of trauma (e.g., abuse vs. neglect during childhood) rather than who perpetrated the trauma. This contrasts with recent research on trauma perpetrated by someone upon whom the survivor relies and/or trusts (i.e. betrayal trauma), which many studies show has a uniquely pernicious association with several forms of personality pathology. However, this has not yet been examined with respect to schizoid pathology specifically. In this study, we examined the relative associations between trauma varying degrees of betrayal and schizoid personality pathology in a sample recruited from Amazon's Mechanical Turk (N = 300) using a Bayesian approach to structural equation modeling. Results suggest that interpersonal trauma in general was associated with higher levels of schizoid pathology. Findings further indicate that for men but not women, trauma with a high degree of betrayal was uniquely associated with schizoid pathology. These findings contribute to the growing body of research suggesting the influence of interpersonal trauma in general and betrayal trauma in particular on personality pathology and have implications for future research on and intervention with people with high levels of schizoid pathology.
