The university environment poses a high risk of spreading infectious diseases, particularly the 2009 pandemic influenza H1N1, as it is a mass gathering place for youth. This study aimed to evaluate the predictors of stress symptoms among Chinese university students during the 2009 H1N1 influenza pandemic. Material/Methods: We used a self-reported questionnaire, the PTSD (posttraumatic stress disorder) Checklist-Civilian Version (PCL-C) to evaluate the stress symptoms among Chinese university students from Heilongjiang (n=455), Beijing (n=106), Shanghai (n=419) and Sichuan (n=102). We then analyzed the predictors of stress symptoms.
Output:
Predictors of symptoms of posttraumatic stress in Chinese university students during the 2009 H1N1 influenza pandemic
