Symptom correlates of posttraumatic stress disorder in clients with borderline personality disorder

Limited research has examined the clinical and functional impact of concurrent posttraumatic stress disorder (PTSD) in people with borderline personality disorder (BPD). Such information is particularly lacking for BPD clients with the most disabling symptoms: those who meet criteria for severe and persistent mental illness. We evaluated individuals with severe mental illness to assess whether PTSD in individuals with BPD was associated with more severe symptoms and impaired functioning than BPD alone and replicated these findings in an independent sample. In both the studies, the clients with PTSD and BPD reported significantly higher levels of general distress, physical illness, anxiety, and depression than those with BPD alone. Because individuals with both of these disorders are likely to require more intensive clinical services to reduce distress and improve functioning, work is needed to develop and evaluate interventions designed to address these comorbid conditions.
