Abstract: Introduction: Trauma exposure and post-traumatic stress disorder (PTSD) are associated with high rates of co-occurring personality pathology, including Obsessive Compulsive Personality Disorder (OCPD). OCPD is characterized by rigidity and perfectionism, leading to internalized distress, interpersonal difficulties, and lower quality of life (QOL). Individuals with OCPD often report high levels of anger, which may exacerbate distress and interpersonal issues. However, the relationship between OCPD, anger, and QOL in trauma-exposed Veterans remains understudied. Materials and methods: 92 Veterans with warzone trauma, hyperarousal symptoms, and moderate to severe problems with anger were recruited from a VA Medical Center for a study on cognitive-behavioral therapy for anger. Assessments included standardized interviews on demographics and trauma history, as well as self-reports on OCPD and borderline personality disorder (BPD) traits, anger, and QOL. Results: OCPD scores were significantly correlated with higher state anger (r = 0.276, p = 0.013), trait anger (r = 0.275, p = 0.016), and lower social QOL (r = 0.344, p = 0.002). BPD scores were similarly associated with higher state (r = 0.242, p = 0.031) and trait anger (r = 0.291, p = 0.011), but had lower QOL in all domains. Conclusion: In this exploratory analysis, OCPD traits in trauma-exposed Veterans were linked to higher anger and lower social QOL, with effect sizes comparable to BPD traits. This highlights the importance of screening for OCPD traits to inform treatment strategies and improve outcomes, especially given that OCPD traits receive less clinical attention than BPD traits.
