Journal of Clinical Psychology
|September 1, 1986
Summary
Combat intensity and homecoming perceptions significantly differentiated Vietnam veterans with post-traumatic stress disorder (PTSD) from controls. Early life and preservice factors did not distinguish the groups.
Area of Science:
- Psychiatry
- Psychology
- Military Medicine
Background:
- Post-traumatic stress disorder (PTSD) is a significant concern among combat veterans.
- Understanding the contributing factors to PTSD in veterans is crucial for developing effective interventions.
Purpose of the Study:
- To compare Vietnam combat veterans diagnosed with PTSD to combat veteran controls.
- To identify factors differentiating PTSD and non-PTSD combat veterans.
Main Methods:
- A structured interview was used to evaluate 50 Vietnam combat veterans with PTSD and 50 combat veteran controls.
- Assessments included childhood, family history, preservice, combat, and postdischarge experiences.
Main Results:
- Significant differences were found in the intensity of combat experiences between the groups.
- Perceptions of homecoming experiences also significantly differed between PTSD and control groups.
- Early history and immediate preservice factors did not differentiate the groups.
Conclusions:
- The intensity of combat and homecoming experiences are key factors associated with PTSD in Vietnam veterans.
- Preservice and early life factors appear less critical in differentiating PTSD in this cohort.

01:20Traumatic Memory
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual remembers mundane...
