社会支持对青少年创伤后成长的影响:状态希望和积极重评的中介作用
The Relationship Between Social Support and Posttraumatic Growth:The Mediated Role of State Hope and Positive Reappraisal

采用创伤暴露程度问卷、社会支持问卷、状态希望量表、认知情绪调节量表和创伤后成长问卷，以雅安地震2.5年后的397名中学生为被试，考察其社会支持、状态希望、积极重评与创伤后成长（PTG）之间的关系。结果发现，雅安地震2.5年后青少年的社会支持可以直接正向预测PTG，不过，在社会支持与PTG之间纳入状态希望和积极重评后，社会支持不能直接地促进PTG，但却可以分别通过状态希望和积极重评来促进PTG，还可以经过状态希望由积极重评的多重中介来正向预测PTG。
The current study aimed to examine the mediating roles of hope and reappraisal in the relation between social support and posttraumatic growth (PTG). Three hundred and seventy-nine adolescents participated in this study 2.5 years after the Ya'an earthquake. The participants were asked to report on the traumatic exposure questionnaire, the social support questionnaire, the state hope inventory, the cognitive emotion regulation questionnaire, and the posttraumatic growth inventory. We built structural equation models to examine the mediating roles of hope and positive reappraisal in the relation between social support and PTG. The results showed that social support had a direct and positive effect on PTG. However, the direct effect became non-significant when hope and positive reappraisal were added into the relation between social support and PTG. In addition, we found that social support indirectly exerted positive effects on PTG by hope and positive reappraisal, respectively. More importantly, social support had a multiple mediating effect on PTG by hope via positive reappraisal.
