Persistent somatic symptom severity in patients with borderline personality disorder: Trauma-related symptoms as mechanism for improvement during inpatient dialectical behavior therapy

While multiple factors contribute to baseline PSS severity in BPD patients, improvements in PTSD symptoms appear to play a key role in the reduction of somatic complaints during inpatient DBT. This highlights the importance of addressing PTSD-related distress in treatment to achieve broader symptom relief. Future research should explore the mechanisms underlying this relationship and assess whether targeted interventions for PTSD within DBT could enhance outcomes for patients experiencing PSS.
