About this trial

The goal of this clinical trial is to learn if a new therapy called Acceptance- and Mindfulness-Based Exposure Therapy (AMBET) helps treat post-traumatic stress disorder (PTSD) in people who survived a cardiac arrest. This study will compare AMBET to another psychotherapy treatment called Present Centered Therapy (PCT) to see which therapy is more effective in treating PTSD.

The main questions it aims to answer are:

Does AMBET reduce PTSD symptoms in survivors of cardiac arrest? How do the benefits of AMBET compare to PCT?

Participants will:

* Be randomly assigned to receive either AMBET or PCT * Attend 12 hours of individual psychotherapy sessions over about 12 weeks * Complete short weekly surveys about their mood and behaviors online * Wear a Fitbit device to track sleep and activity during the study * Do brief homework assignments between sessions
