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

A Pilot Effectiveness Trial of Cognitive Processing Therapy Augmented With Suicide Risk Management for Individuals With Comorbid PTSD and BPD

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: CPT + SRM; Participants will be randomized to teletherapy sessions of Cognitive Processing Therapy + Suicide Risk Management for PTSD-BPD which will be administered twice weekly over 6 weeks, for a total of 12 sessions.	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.
Experimental: TAU + SRM; Participants will be randomized to teletherapy sessions with only Suicide Risk Management for PTSD-BPD which will be administered once a week for 6 weeks, for a total of 6 sessions.	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.

Substance Use Inventory (SUI)	A brief measure with detailed questions regarding participants' use and primary route of different substances they used in the last seven days. The individuals' are also asked about the average dollar amount spent on each drug and in a single day. (Weiss, et al., 1995).	Baseline, 3-weeks, Post-treatment/6-weeks, 3-months follow-up
PTSD Checklist-5 (PCL-5) [SELF-REPORT]	A 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. It is used to help screen individuals for PTSD as well as monitor their symptom changes during and after treatment.	Baseline, once a week while in treatment (for 6 weeks)
Acceptability of Intervention Measure (AIM)	A 4-item measure which asks therapists and patients about their perceived acceptability of the intervention on a 5-point Likert scale.	Baseline and Post-treatment/6-weeks
Treatment sessions attended	Feasibility as measured by number of treatment sessions	Pre-post treatment (6 weeks)
Rate of dropout	Feasibility as measured by rate of treatment dropout	Pre-post treatment (6 weeks)
Emotional Reactivity and Attentional Biases via Oddball task	Used as a behavioral measure of changes in emotional reactivity and attentional biases- our two propose mechanisms of change in CPT+SRM. The oddball task is computer-based task (Hayes, et al., 2009) designed to measure emotional reactivity and attentional biases. Participants will view a pseudorandom distribution of brief presentations of emotionally-salient distractors (negative images depicting mutilations, burn victims, attacks, sick individuals), neutral distractors (matched with negative images for luminance, presence of human figures, chromatic features), baseline standards (squares), and attention "targets" (circles) in an event-related design. Participants will be instructed to press the same button for all stimuli, but a different button for attention targets. Behavioral changes associated with emotional reactivity and attention bias will be assessed using response latency and accuracy scores for emotional and attention targets, respectively.	Baseline, Post-treatment/6-weeks, 3-months follow-up
Mental Health Involvement Scale [SELF-REPORT]	A 9-item measure used to inquire about other ancillary services (e.g., group treatment, couples/family therapy) that participants are receiving throughout the study. This is a measure developed and used in prior research by the investigative team, but currently does not have published psychometric properties.	Post-treatment/6-weeks
Measure of CPT+SRM Uptake [SELF-REPORT]	Measures uptake of the treatment using an adapted measure from LoSavio, et al. (2019). This brief survey will assess clinicians' ongoing use of CPT+SRM since their participation in the study (e.g., whether they continue to offer CPT+SRM, the number of clients they have offered CPT+SRM to, average number of sessions attended, etc.) and further inform whether our training methods and treatment will have a lasting impact on practice approaches in community settings. There are no psychometric data available for this questionnaire.	9-months after concluding treatment with the last study participant
