The current study investigated the underlying dimensions of DSM-5 PTSD symptoms in an epidemiological sample of Chinese earthquake survivors. The sample consisted of 810 females and 386 males, with a mean age of 47.9 years (SD=10.0, range: 16-73). PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and alternative models were evaluated with(More)
Eye tracking is the focus problem in the researching domain of human-machine interaction and computer vision in recent years. The method of using a single eye location and detection algorithm has poor real-time performance. So a new eye tracking method is proposed in this paper. This method combines the location and detection algorithm with the grey(More)
We examined the convergent validity of the Chinese Personality Assessment Inventory (CPAI; Cheung, Leung, et al., 1996), an indigenously constructed measure, by comparing its patterns of correlations with the MMPI-2 (Butcher et al., 2001). A valid sample of 147 Chinese students took both the CPAI and the MMPI-2. Results provide preliminary support for the(More)
The present study investigated the factor structure of posttraumatic stress disorder (PTSD) symptoms measured by the PTSD Checklist (PCL) in two large samples exposed to different traumatic events (an earthquake and a violent riot) from China. Despite the samples' difference in type of trauma, demographics, symptom severity, and elapsed time since trauma(More)
The symptoms of posttraumatic stress disorder and associated risk factors were investigated among health care workers in earthquake-affected areas in southwest China. 343 health care workers completed the Chinese version of the Impact of Event Scale-Revised 3 mo. after the Wenchuan Earthquake. The prevalence of probable PTSD was 19%. The significant risk(More)
Many military applications require the distance information from a moving vehicle to targets from video image sequences. For indirect driving, lack of perception of depth in view hinders steering and navigation. In this paper we present a real-time depth detection system and a thorough discussion in performance analysis is presented. DepthFinder can be used(More)
BACKGROUND This study investigated an alternative five-factor diagnostic model for posttraumatic stress disorder (PTSD) symptoms, and tested external convergent and discriminant validity of the model in a young Chinese sample of earthquake survivors. METHODS A total of 938 participants (456 women, 482 men) aged 15-20 years were recruited from a vocational(More)
