Cognitive Processing Therapy (CPT) for Posttraumatic Stress Disorder and Borderline Personality Disorder (PTSD-BPD)

Summary

Posttraumatic Stress Disorder (PTSD) with co-occurring Borderline Personality Disorder (BPD) (i.e., PTSD-BPD) is common (as high as 58%), debilitating, costly, and limited treatment options available for this population. PTSD-BPD is associated with even greater functional impairment and higher healthcare burden than either disorder alone. There are surprisingly few treatments available for this clinical profile, despite its association with major negative health outcomes, cost, and morbidity. There is a pressing need to innovate treatments that can effectively and efficiently treat PTSD-BPD. The existing treatments used for PTSD-BPD are lengthy, laborious, resource-intensive, and require complete cessation of suicidal behaviors prior to treatment. Furthermore, no integrated treatment has been innovated to deliver the active ingredients to efficiently affect the mechanisms underpinning this comorbidity. The investigators propose to examine an adapted version of a first-line PTSD intervention, Cognitive Processing Therapy, augmented with a Suicide Risk Management, i.e., (CPT+SRM) as a brief (12 sessions) and more parsimonious treatment alternative that strategically targets shared mechanisms underpinning PTSD and BPD. The purpose of this pilot study is to 1) collect initial feasibility, acceptability, and safety data on this adapted treatment, 2) conduct a pilot randomized clinical trial evaluating the efficacy of CPT+SRM versus Treatment as Usual (TAU) + SRM, and 3) evaluate two targets (i.e, improvements in emotional intensity and cognitive dysfunction) as mechanisms leading to change in our primary outcomes. Both treatment conditions will be administered via telehealth.

Potential benefits include reduction in participants' PTSD, BPD and other mental health symptoms. Additionally, this work could benefit the community by improving the treatment repertoire for PTSD-BPD. Potential risks include emotional distress, suicidality, and/or self-harm. Participants may experience discomfort and/or distress while discussing participants trauma(s) and mental health. These risks will be mitigated using a suicide risk management protocol which therapists in the assessment of risk and protective factors of suicide, followed by documentation for the decision-making around the management of risk.

Interventions

BEHAVIORAL

Cognitive Processing Therapy with Suicide Risk Management

CPT is an evidence-based treatment for PTSD. This first-line treatment for PTSD will be adapted and combined with SRM into 12 sessions, 60-90 minutes targeting both PTSD and BPD. Individuals assigned to this intervention will attend treatment sessions, and be asked to do treatment homework at home. The primary outcomes are PTSD and BPD severity.

BEHAVIORAL

Treatment as Usual with Suicide Rick Management

In the Suicide Risk Management only condition, participants will receive 6 weekly sessions over the course of six weeks focused on suicide stabilization and management. Each SRM session will be variable lengths, depending on the participants' suicide risk and can be up to 60 minutes.
