About the study

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.
