Co-occurring hazardous drinking, anxiety disorders, and PTSD are problematic combinations of mental health concerns experienced by deployed Veterans. Veterans who have been deployed are at particular risk for experiencing problems in functioning and reintegration related to mental health disorders and hazardous drinking. Co-occurring anxiety and hazardous drinking heavily impact psychosocial functioning and quality of life. Although cognitive behavior therapy (CBT) can promote psychological recovery through improvements in functioning and quality of life, most CBT protocols do not address co-occurring disorders, leading to inefficient and disjointed treatment. The current research seeks to adapt and test the Unified Protocol (UP) for deployed Veterans with hazardous drinking. The use of combined CBT for both anxiety disorders and hazardous drinking has the potential to more efficiently and effectively improve functioning, reduce symptoms, and promote psychosocial recovery.
