Impact of personality and social support on posttraumatic stress disorder after traffic accidents
This study aims to investigate the relationships of personality and social support with posttraumatic stress disorder (PTSD) after traffic accidents.
The 90 Symptom Checklist (SCL-90) and Eysenck Personality Questionnaire (EPQ) were completed 1 week after trauma. The Checklist-Civilian Version (PCL-C) was surveyed 3 months after discharge.
PCL-C score of 38 was used as cutoff point. The older age and lower education significantly increased the PTSD incidence. SCL-90 score was positively correlated with PTSD symptom score. The psychoticism (P) (0.230) and neuroticism (N) (0.302) was positively correlated with PTSD symptom score in a linear relationship. Objective support, subjective support, exploitation degree, and social support were negatively associated with PTSD scores. Force symptoms, psychoticism, subjective support, introversion, and extroversion could explain 65.0% of degree of variation for PTSD with the estimated standard error of 4.758.
PTSD associated social factors include force symptoms, psychoticism, subjective support, introversion, and extroversion.
