This study looks at how teens with trauma-related symptoms respond to stress and strong emotions. We will measure brain activity, body responses, and behavior during activities that involve reacting to possible threats, managing emotions, and imagining parts of their own stressful or traumatic experiences more than once.

The goal of this research is to better understand how repeating these imagining activities affects teens. We also want to learn whether a teen's reaction to stress and their ability to manage emotions are connected to how they respond to imagining stressful events.

What we learn may help improve treatments for posttraumatic stress disorder (PTSD) and help identify which teens are most likely to benefit from these treatments, based on brain, body, and behavior responses.
