A Case Formulation Approach to Cognitive Processing Therapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Recent estimates suggest that over 610,000 US Veterans treated by the Veterans Health Administration (VHA) suffer from PTSD, a disorder that can be chronic and debilitating. The heterogeneity of the 20 symptoms of PTSD; comorbidity with disorders such as depression, panic, and substance use; high rates of lingering effects of physical injury; and suicidality all contribute to complex clinical presentations and can exact a significant toll on functioning, quality of life, and well-being even decades after exposure to the traumatic event. Perhaps spurred by the President's New Freedom Commission on Mental Health, psychosocial rehabilitation has shifted from the periphery in mental health recovery models to a more primary focus in clinical settings, including recommendations for use of psychosocial rehabilitation techniques in trauma-focused mental health care. Support for the efficacy of psychosocial rehabilitation techniques in PTSD recovery programs has burgeoned in recent years and data supporting psychological treatments for PTSD has increased exponentially, yet the two approaches to recovery have largely remained independent. Cognitive Processing Therapy (CPT), the evidence-based psychotherapy (EBP) for PTSD most frequently delivered within VHA, yields large magnitude reductions in primary PTSD outcomes. Corresponding gains in occupational, social, leisure, and sexual functioning, and in health-related concerns have also been demonstrated. Despite CPT's effectiveness, there is room for improvement in overall outcomes and patient engagement. Further, improvements in functioning and quality of life are more modest than those observed in PTSD and associated mental health symptoms. Prior work suggests that unaddressed difficulties in functioning contribute to premature dropout from EBPs for PTSD among Veterans. Directly targeting impairments associated with psychosocial functioning has the potential to substantially increase the scope of recovery beyond the core symptoms of PTSD and facilitate greater patient engagement, resulting in more Veterans benefitting from CPT. Modifying the CPT protocol to personalize the intervention for the individual patient has resulted in better overall response rates for a wider variety of patient populations suffering from complicated clinical presentations. Case formulation (CF) is a well-established approach to cognitive-behavioral treatment that facilitates a collaborative process between providers and patients to guide the tailoring of treatment to meet idiosyncratic patient needs. Integrating CF strategies into the existing CPT protocol will enable providers to personalize CPT to directly address impairment in functioning as well as provide the latitude to directly intervene with the complex challenges that threaten optimal outcomes within the context of trauma-focused therapy. CF-integrated CPT (CF-CPT) expands and enhances the CPT protocol to facilitate a personalized and flexible approach to treating PTSD that prioritizes the administration of the full dose of CPT while expanding the protocol to directly target important domains of functioning and result in more holistic outcomes. This controlled treatment outcome trial will randomize a national sample of CPT providers (Veteran n = 200; provider n = 50) to either deliver CF-CPT or CPT to compare the relative effectiveness of CF-CPT to CPT in improving primary outcomes, including Veterans' psychosocial functioning, quality of life and well-being over the course of treatment and 3-month follow-up as compared to Veterans who receive standard CPT. Further, Veterans who receive CF-CPT will demonstrate greater reductions in PTSD and depression over the course of treatment and 3-month follow-up than those who receive CPT. This study also seeks to determine the effectiveness of CF-CPT as compared to CPT in improving Veterans' treatment engagement (CF-CPT will demonstrate higher rates of Veteran treatment completion than CPT). This study will valuate CF-CPT's indirect impact on Veterans' psychosocial functioning and PTSD/depression symptomology Change in functioning, quality of life, and well-being \& PTSD and depression will be associated with improvement in the idiosyncratic clinical challenges targeted by the CF. This study will also examine between-group differences across secondary outcomes (e.g. anger, anxiety, health concerns, sleep, numbing/reactivity) and describe the frequency and type of the clinical and rehabilitative needs of the Veterans and the type and duration of divergences (e.g. rehabilitative techniques) made by providers.
