To investigate the effects of posttraumatic stress disorder and its various symptom clusters on suicide ideation in post-earthquake adolescents, and to examine the moderating role of feelings of safety in this, the present study administered the Traumatic Exposure Questionnaire, Center for Epidemiologic Studies Depression Scale for Children, modified DSM-5 PTSD checklist, Feelings of Safety Questionnaire, and Youth Risk Behavior Survey Questionnaire on 1136 adolescents 8.5 years after Wenchuan earthquake. It was found that PTSD, negative cognitions and mood symptoms, hyper-arousal symptoms had significantly positive effects on suicide ideation, while the re-experiencing symptoms and avoidance symptoms did not significantly predict suicide ideation. The results also showed that feelings of safety played a negative moderating role between re-experiencing symptoms, negative cognitions and mood symptoms, hyper-arousal symptoms, PTSD and suicidal ideation, but did not play a moderating role between avoidance symptoms and suicidal ideation. These results suggest that PTSD symptom clusters differ in their predictive effects on suicidal ideation in post-earthquake adolescents, and feelings of safety play a moderating role in some of these effects.
