Summary
This study found no personality differences between Vietnam veterans with PTSD based on trauma exposure levels. However, a distinct PTSD personality profile emerged, marked by high Neuroticism and low Agreeableness.
Area of Science:
- Psychology
- Military Mental Health
- Trauma Studies
Background:
- Combat-related Post-Traumatic Stress Disorder (PTSD) significantly impacts veterans' lives.
- Understanding the personality traits associated with PTSD is crucial for effective treatment.
- Previous research has explored personality correlates of PTSD, but findings require further clarification.
Purpose of the Study:
- To investigate personality differences among Vietnam veterans with PTSD based on varying levels of combat exposure.
- To establish a normative personality profile for individuals diagnosed with combat-related PTSD.
Main Methods:
- One hundred Vietnam veterans diagnosed with combat-related PTSD participated.
- Participants completed the NEO Personality Inventory (NEO-PI) and the Combat Exposure Scale.
- Subjects were categorized into three groups according to their level of trauma exposure.
Main Results:
- No statistically significant differences in personality profiles were observed across the three trauma exposure groups.
- A characteristic NEO-PI profile for combat-related PTSD was identified.
- This profile is defined by exceptionally high Neuroticism scores (T > 75) and markedly low Agreeableness scores (T < 25).
Conclusions:
- Combat exposure level does not appear to differentiate personality profiles in veterans with PTSD.
- A specific personality configuration, high in Neuroticism and low in Agreeableness, is associated with combat-related PTSD.
- These findings contribute to a deeper understanding of the psychological landscape of PTSD in veterans.

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...
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:27Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

01:27Dissociative Disorders
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.
