Exposure by Assessment: Effects of Daily AMQ-Based EMA of an Intrusive Trauma Memory in PTSD

Intrusive re-experiencing is a hallmark of PTSD. The study applies ecological momentary assessment (EMA) of participants' trauma memories (active group) vs. EMA of a neutral memory (control group) to test whether the active intervention can reduce intrusive symptoms severity and overal PTSD symptom severity in general.
