ABSTRACT

OBJECTIVE: To explore the mediating role of social support,psychological resilience and rumination between personality traits and post-traumatic stress response,and discover methods for controlling and intervening post-traumatic stress response in armed police soldiers. METHODS: By judgment sampling method,895 armed police soldiers were selected and investigated by simple version of Eysenck Personality Questionnaire,Traumatic Event Scale of Essen Trauma Inventory,Perceived Social Support Scale,Rumination Reaction Scale,Resilience Scale and Impact of Event ScaleRevised. RESULTS: There were 22. 46%( 201/895) of armed police soldiers who had experienced traumatic events. The scores of post-traumatic stress response were( 34. 6 ± 13. 3). The soldiers with light,medium and heavy levels of posttraumatic stress response were 33. 33%,45. 77% and 20. 90%,respectively. The psychoticism and neuroticism dimension in personality traits of soldiers in trauma group were negatively correlated with social support and psychological resilience( P < 0. 01),and positively correlated with rumination and the level of post-traumatic stress response( P < 0. 01). The extraversion dimension in personality traits was positively correlated with social support and psychological resilience( P <0. 01) and negatively correlated with rumination and the level of post-traumatic stress reactions( P < 0. 05). The personality traits had direct effect on the level of post-traumatic stress response( P < 0. 01),but there was no direct effect after adding mediators( P > 0. 05). Through social support,rumination and psychological resilience,personality traits could produce multiple mediating effects on the level of post-traumatic stress response. The social support and rumination showed mediating effect that accounting for 86. 61% of the total mediating effect. CONCLUSION: The social support,psychological resilience and rumination had mediating effect in personality traits and level of post-traumatic stress response.The social support and rumination are two key factors of the intermediate path,which is the main point of psychological rescue and intervention for the armed police soldiers.
