Revista Espanola De Salud Publica
|April 15, 2014
Summary
Neuroticism is a significant risk factor for developing post-traumatic stress disorder (PTSD) after experiencing trauma. This finding aids in creating better prevention and treatment strategies for PTSD.
Area of Science:
- Psychiatry
- Psychology
- Epidemiology
Background:
- Conflicting evidence exists regarding neuroticism's role as a post-traumatic stress disorder (PTSD) risk factor.
- Previous studies have yielded inconsistent results on the association between neuroticism and PTSD.
- Understanding this relationship is crucial for effective mental health interventions.
Purpose of the Study:
- To quantify the association between neuroticism and PTSD.
- To determine the direction and magnitude of this relationship.
- To investigate potential moderator variables influencing the effect size.
Main Methods:
- A systematic review and meta-analysis were conducted.
- Searched multiple databases (Medline, PsycINFO, etc.) and contacted researchers.
- Included 34 studies with 9,941 participants, analyzing data using a random-effects model.
Main Results:
- A significant positive association was found between neuroticism and PTSD (r+ = 0.371).
- Publication bias was assessed and deemed not a significant threat.
- Ethnicity reporting, age, and sample type were identified as potential moderators.
Conclusions:
- Neuroticism is confirmed as a risk factor for PTSD in individuals exposed to trauma.
- Findings support the development of targeted preventive interventions.
- Results inform clinical practice for PTSD treatment.

Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Karen Horney's psychoanalytic theories emphasize the potential for self-realization and the importance of addressing social and cultural, rather than biological, factors in personality development. She challenged traditional Freudian views, particularly Freud's concept of "penis envy," which she argued stemmed from cultural influences rather than inherent biological differences. Horney believed that any sense of inferiority in women was a result of societal conditioning, such as...

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
