The goal of this trial is to test how augmented reality exposure therapy (ARET) may potentiate the effects of traditional exposure therapy administered to U.S. military personnel diagnosed with PTSD. 40 adult males and females over the age of 18 that have served, or are currently serving, in the U.S. military, with a current diagnosis of PTSD, will be recruited. Participants will be randomized into two groups: 20 participants will receive ARET + traditional ET, with the remaining 20 to receive traditional ET only. The main questions this trial aims to answer are:
* what are the different clinical and psychosocial functioning outcomes between veterans/active-duty personnel with PTSD who receive ARET + traditional ET versus traditional ET only
* what are the differences in acceptance and satisfaction of treatment, between ARET + traditional ET and the traditional ET-only group

The goal of this clinical trial is to learn if training with the Prism system can reduce PTSD symptoms in US military Veterans and civilians with PTSD. Prism is a form of neurofeedback training that uses EEG signals to promote self-regulation of brain function. The main question this study aims to answer is:
Does Prism training lead to decreased PTSD symptoms in US Veterans and civilians when used in addition to usual PTSD treatment?
Researchers will compare Prism training to a sham training (a look-alike training that does not provide real feedback on brain activity) to see if Prism training decreases PTSD symptoms.
Participants will:
* Complete two one-hour in-person training sessions a week for about 8 weeks (15 sessions)
* Complete two booster training sessions one month and two months after finishing the main training course
* Participate in three detailed interviews: one before training, a second after nine weeks of training, and a third one month after the last booster training session (about 20 weeks after the initial visit)

Adjustment Disorder (AjD) is the most common mental health condition diagnosed in Active Duty personnel, and is diagnosed following an extreme stress event such as traumatic loss of a comrade, serious accident or injury, or other intense stress event. Despite its high prevalence, no evidence based treatment for AjD has been subjected to randomized controlled trials. This study seeks to build on the research team's pilot work across several disorders study to benefit service members and Veterans with AjD, a highly prevalent but frequently inadequately treated condition.
The investigators will compare the effects of Transdiagnostic Behavior Therapy (TBT) vs treatment as usual which is Moving Forward Problem Solving Therapy (TAU-PST) on AjD symptom outcomes. The investigators hypothesize that TBT will result in greater overall symptom reduction compared to TAU-PST.
