Seeking Individuals with Complex PTSD: Trauma Symptom Tracking Study

Krista Engle is looking for participants for her online dissertation study. The purpose of the Trauma Symptom Tracking Study is to learn more about how individuals with Complex PTSD cope with trauma and how their symptoms impact their daily lives.

This study has two parts and will be conducted completely online or via a smartphone. Part 1 of the study includes a survey about participants’ trauma history and trauma-related symptoms to determine whether they are eligible for Part 2 of the study. Part 2 of the study includes additional measures assessing participants’ mental health and coping skills followed by the completion of short, daily surveys about the person’s trauma symptoms using their phone for 2 weeks. Participants must participate in Part 1 in order to be considered for Part 2. 

Participation in Part 1 is not expected to exceed 15 minutes, and participation in Part 2 is not expected to exceed 3 hours over the course of 2 weeks. 

Participants can receive up to $25 for the completion of study procedures.
