Official title: Enhancing Intensive Transdiagnostic Cognitive Behavioral Therapy for Veterans With PTSD and Anxiety Disorders

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to compare two different intensive formats of delivering cognitive-behavioral treatment for people with PTSD and anxiety disorders. The main questions it aims to answer are: - Is iTCBT delivered in individual and group formats more effective than TAU in improving anxiety symptoms and quality of life? - For treatment non-responders, is iTCBT-Enhanced more effective than TAU improving anxiety symptoms and quality of life? - Does iTCBT-Individual produce a larger improvement in anxiety and quality of life compared with iTCBT-Group? Participants will undergo several assessments throughout the course of the study. Based on randomization, they will receive: (1) iTCBT in an individual format over a 2-week period, (2) iTCBT in a group format over a 2-day period, or (3) usual care. Those who do not show a response to treatment will receive 4 additional individual therapy sessions.

Clinical Trial Description

Anxiety disorders and posttraumatic stress disorder (PTSD) are among the leading mental health problems in the nation and are highly prevalent among service members and Veterans. The process of recovery and reintegration across the lifespan for military personnel with PTSD and anxiety disorders remains a significant problem. Due to the debilitating nature of these disorders, resuming and participating in major life roles following deployment can be challenging and often leads to avoidance of everyday activities and social withdrawal. Consequences of untreated anxiety-based disorders range from substantial impairment in social, vocational, emotional and physical functioning to high rates of suicide. Despite the debilitating nature of posttraumatic stress and anxiety, these disorders can be successfully treated with CBT. However, relatively few Veterans take advantage of these treatments. One explanation is that individual- and systemic- level barriers to treatment engagement are inherent in the structure of standard CBT delivery formats, which require weekly appointments over a 3 to 4-month period. Furthermore, because current CBTs are disorder-specific and often do not directly address psychiatric comorbidity, individuals frequently need to seek additional treatment after completing one course of CBT. These collective barriers point to the need for improved treatment delivery methods. Transdiagnostic treatment approaches hold potential in addressing the many barriers associated with treatment engagement. Transdiagnostic approaches distill the same treatment principles embedded across different protocols for anxiety disorders and PTSD into a single protocol without targeting a specific disorder. Fear is a common element across these disorders but the source of fear and how symptoms manifest differentiates one disorder from another. Although transdiagnostic approaches show excellent potential as a single treatment for multiple disorders, few studies to date have systematically examined the effectiveness of transdiagnostic treatment with a military population. Research also indicates that service members with anxiety disorders often prefer treatment in an individual therapy format. Group treatments typically show higher rates of dropout, which supports the importance of treating anxiety using individual formats. Similarly, given the many barriers associated with the structure of traditional psychotherapy delivery, more attention in recent years has been directed at examining intensive or massed treatment approaches in delivering trauma-focused treatment. Such approaches seek to shorten the overall length of treatment by providing psychotherapy in longer and stronger doses. The proposed clinical trial tests two different delivery formats of iTCBT (Individual vs. Group) and the enhancement of iTCBT for participants who do now show significant improvement following a course of iTCBT. Veterans and service members with PTSD and anxiety will be recruited for the study. The extended version of iTCBT (iTCBT-E) will provide 6 additional hours of individual treatment over 2 weeks. Differences in outcomes between participants who receive the intervention in individual versus group formats will also be examined. ;
