title: The factor structure of posttraumatic stress disorder symptoms in patients with traumatic spinal cord injuries.
abstract: The current study investigated the factor structure of posttraumatic stress disorder (PTSD) symptoms in a sample of 256 patients with traumatic spinal cord injuries (SCI) in China. The confirmatory factor analysis results showed that a five-factor model composed of intrusion, avoidance, emotional numbing, dysphoric arousal, and anxious arousal fits the data significantly better than the tripartite DSM-IV model and the two well-supported four-factor models, and the C3 symptom (inability to recall important aspect of the trauma) loaded weakly on its corresponding factor. Implications and limitations for the results are discussed.
