Posttraumatic Stress Disorder
Conditions
Brief summary
The aim of the project is to advance our understanding of how individuals with Posttraumatic Stress Disorder (PTSD) experience symptoms in their every-day lives when they are in their home environment. To date, all PTSD assessments are retrospective; individuals with PTSD are asked to recount and report their symptoms over the past weeks or months. Such assessment procedures are negatively impacted by individuals' abilities to accurately recall information. Moreover, retrospective assessments provide little information about how symptoms are experienced in the moment and how these experiences then lead to other behaviors. The proposed project addresses these limitations by assessing PTSD symptoms and associated biological markers (e.g., sleep, heart rate, heart rate variability) in real-time by asking subjects to wear a smart device and complete brief surveys. Data will be collected from 50 individuals with PTSD and 20 healthy controls to help us better understand individuals' real-time experience with PTSD and lay the foundation to develop algorithms for possible in-the-moment interventions in the future.

Inclusion criteria
for participants with PTSD: Individuals are eligible for the current study if they: 1. Are 18 years or older 2. Are fluent in English 3. Have an active smart phone or smart device with full data and Bluetooth capability 4. Have experienced a Criterion A traumatic event during their lifetime 5. Have a PTSD diagnosis verified by the Clinician Administered PTSD Scale for DSM-5 and a symptom severity score of 35 or higher. 6. Are willing and able to complete self-report measures and clinician-rated assessments at multiple time points over the course of the study 7. Are willing to wear a smart device 24/7 over the course of one month.
Exclusion criteria
for PTSD participants: Individuals are excluded from the current study if: 1. The traumatic event occurred in the past month 2. They are currently suicidal or homicidal 3. They have a history of psychosis or mania 4. They have a known, diagnosed heart condition 5. They are currently receiving treatment for their PTSD or have completed an evidence- based PTSD treatment in the past 3 months 6. They have a serious or unstable medical illness or instability for which hospitalization may be likely 7. Subjects who, at the time of consent, appear to have extenuating life circumstances (unstable housing, no internet access, etc.) which, in the judgement of the Principal Investigator, could affect their ability to participate in the study Inclusion Criteria for healthy controls: Individuals are eligible for the current study if they: 1. Are 18 years or older 2. Are fluent in English 3. Have an active smart phone or smart device with full data and Bluetooth capability 4. Are willing and able to complete self-report measures and clinician-rated assessments at multiple time points over the course of the study 5. Are willing to wear a smart device 24/7 over the course of one month.
