Thesis related to PTSD
I am having trouble deciding on a thesis project for my clinical psychology phd. I am involved in a lab that studies PTSD in military and law enforcement populations. I want to do something related to PTSD and positive psychology. I have so many ideas, but none seem feasible for gathering data from a student population. I need to find something that will be relatively straightforward and not leave me collecting data for 5 years. Any ideas or specific areas of the literature I should look?

Hi,
Given that you want to collect data from students, a good strategy is to study mechanisms and protective processes rather than trauma exposure itself. You cannot ethically or practically induce trauma in students, but you can study variables that predict resilience, recovery trajectories, or symptom buffering.
The proposed strategy will tie with your military and law enforcement lab if frame your work as:
“Identifying modifiable resilience mechanisms relevant to high-risk occupational trauma populations, tested in a civilian analog sample.”
That keeps your thesis theoretically aligned with your lab while using a feasible population.
The following literature-grounded directions map well onto positive psychology and PTSD theory:
1. Posttraumatic Growth (PTG) Processes
Huge literature, strong theoretical base, very student-sample friendly.
2. Psychological Flexibility & Acceptance (ACT framework)
Strong overlap with both PTSD treatment and positive psychology.
3. Moral Injury, Guilt, and Self-Forgiveness
Especially relevant to military/law enforcement, but can be modeled in civilians.
4. Social Connection as a Resilience Mechanism
Not just “support,” but:
•
Attachment security
•
Perceived mattering
•
Communal coping
•
Loneliness vs. belonging
You can test mediation/moderation with cross-sectional or short longitudinal designs.
5. Positive Emotions and Broaden-and-Build in Trauma Contexts
Fredrickson’s theory fits beautifully.
6. Meaning in Life & Existential Resilience
Classic trauma literature meets positive psychology.
Practical designs to avoid a 5-year data collection nightmare:
Option A: Cross-Sectional + Structural Modeling
Large student sample, strong theory, clean mediation models.
Option B: Short-Term Longitudinal (3–4 waves over a semester)
Lets you test temporal ordering without a multi-year follow-up.
Option C: Micro-Intervention
Randomized to:
•
Self-compassion
•
Gratitude
•
Values clarification Measure PTSD symptoms, affect, meaning, flexibility.
