Influence of betrayal trauma on obsessive-compulsive personality pathology.

OBJECTIVE

Obsessive-compulsive personality disorder (OCPD) is among the most common forms of personality pathology. Research suggests that among the risk factors for OCPD pathology is trauma, although it is unclear which kinds of trauma are most influential. Of particular relevance may be trauma high in interpersonal betrayal, which research suggests has a unique association with many different forms of personality pathology. However, this has not yet been examined for OCPD specifically.

METHOD: In this study, we examined the differential associations between trauma with varying levels of betrayal and OCPD pathology in a sample of women and men recruited online (N = 300) using a Bayesian approach to structural equation modeling.

RESULTS

Results suggest that although general interpersonal trauma was associated with OCPD across the sample, interpersonal trauma high in betrayal was uniquely associated with OCPD for men.

CONCLUSION

These findings have implications for future research on the influence of trauma and personality pathology as well as for the treatment of OCPD specifically. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
