Longitudinal Relationships Between Neuroticism, Avoidant Coping, and Posttraumatic Stress Disorder Symptoms in Adolescents Following the 2008 Wenchuan Earthquake in China

The Wenchuan earthquake, which occurred in southwestern China in May 2008, was a source of severe psychological distress to adolescents. This study explored the developmental trajectory of posttraumatic stress disorder (PTSD) symptoms and the longitudinal relationships between neuroticism, avoidant coping, and PTSD symptoms measured at three time points: 1 year (T1), 1.5 years (T2), and 2 years (T3) after the earthquake. The participants included 636 adolescents from several high schools located in the areas that were most severely affected by the earthquake. Structural equation modeling results revealed bidirectional effects between neuroticism, avoidant coping, and PTSD symptoms. More severe PTSD symptoms predicted higher levels of avoidant coping at T1T2 and T2T3 but only predicted higher levels of neuroticism at T1T2. Higher levels of neuroticism at T1 predicted more severe PTSD symptoms at T1T2, while higher levels of avoidant coping at T1 predicted more severe PTSD symptoms at T2T3.
