An Evaluation of Two PTSD Assessments in an Active Duty and Military Veteran Sample
Given the high prevalence of post-traumatic stress disorder (PTSD) in veterans and active duty military, the focus of this research study is to test the reliability of two new PTSD assessments, the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Symptom Scale Interview for DSM-5 (PSSI-5) and compare …
Functional Magnetic Resonance Imaging Sleep Study With Auditory Stimuli
Background An electroencephalogram (EEG) measures the brain s electrical activity. EEG shows that the louder the sound needed to wake a person, the deeper the person s sleep. Researchers are using functional magnetic resonance imaging (fMRI) to study people during sleep so they can view brain activity in 3D. But …
