Transdiagnostic CBT for Anxiety


Brief description of study

This study is a randomized controlled trial examining the effectiveness of a transdiagnostic cognitive behavioral treatment (CBT) in improving Veterans' community reintegration and quality of life. Veterans with anxiety-based disorders, including posttraumatic stress, panic, social anxiety, and generalized anxiety disorders (with or without co-occurring depression) will be randomized to an intensive CBT (iCBT) treatment delivered over one weekend, standard CBT (sCBT) delivered over 12 weeks or treatment as usual (TAU). The study will also evaluate the potential of the compressed weekend format of iCBT in producing more rapid improvement in outcomes and increasing psychotherapy engagement compared with a standard psychotherapy format. Qualitative interviews will be conducted with Veterans who receive iCBT and their family members to examine how iCBT and environmental factors impacted their process of recovery.

Detailed Study Description

The current project proposes to evaluate a brief but intensive transdiagnostic CBT that simultaneously targets multiple anxiety disorders with or without co-occurring depression. This will be accomplished by evaluating an innovative treatment delivery method that directly addresses barriers associated with standard psychotherapy delivery. The main objectives are to (1) determine if an intensive CBT protocol (iCBT) delivered over one weekend can improve community reintegration, quality of life, and emotional functioning compared with standard CBT (sCBT) and treatment as usual (TAU); (2) examine the rates of psychotherapy engagement in iCBT compared with sCBT; and (3) obtain a deeper understanding, through qualitative interviews with Veterans and their family members, of how iCBT and environmental factors may impact the process of reintegration and quality of life.

The proposed study is a randomized controlled trial with 3 treatment arms. A transdiagnostic group CBT protocol will be compared in a compressed weekend format (iCBT) with a standard group delivery format involving 3 months of weekly sessions (sCBT). A treatment as usual (TAU) condition will be included to compare outcomes. Veterans with one or more anxiety-based disorder(s) (with or without co-occurring depression) will be randomized to one of the three treatment arms. Veterans will be asked to attend a total of four assessments during the study including a baseline evaluation, 1-month, 3-month, and 6-month follow-ups. Qualitative interviews will be conducted with Veterans who completed iCBT and family members.
