To examine the role of the three types of social support as possible moderating factors between post-traumatic stress disorder (PTSD) and its relationship to two domains of the quality of life (QOL).
A cross-sectional survey was done in a local area near the epicenter of the severe earthquake in Wenchuan. The Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV), the standard Chinese 12-item Short Form (SF-12v2), and the Social Support Rating Scale (SSRS) were used to interview a total of 2,080 earthquake survivors in the one-year follow-up period. Multiple regressions were performed to evaluate the moderating role of social support on the relationship between PTSD and QOL.
Among survivors one-year after the Wenchuan earthquake, being a woman (p < 0.01), having a lower level of education (p < 0.01), having a lower level of income (p < 0.01), having a worse housing status (p < 0.05) and having a higher level of exposure (p < 0.05) were risk factors for a poorer QOL (∆R (2) = 0.063). PTSD symptoms negatively influenced the QOL (∆R (2) = 0.145), while social support positively influenced the QOL (∆R (2) = 0.016). However, the interaction between social support and PTSD weakened the negative effect of PTSD on the QOL (∆R (2) = 0.012). Subjective support and support availability moderated the association between PTSD and the QOL (∆R (2) = 0.010).
Subjective support and support availability are more useful strategies to improve the QOL of the earthquake survivors with PTSD symptoms.
探讨三种社会支持类型作为创伤后应激障碍（PTSD）与生活质量（QOL）两个领域之间关系的可能调节因素的作用。
在汶川特大地震震中附近的一个地区进行了横断面调查。采用精神障碍诊断与统计手册第四版（DSM-IV）、标准中文 12 项短式（SF-12v2）和社会支持评定量表（SSRS）对 2080 名地震幸存者进行了为期一年的随访访谈。采用多元回归分析评估社会支持对 PTSD 与 QOL 关系的调节作用。
在汶川地震一年后幸存的人群中，女性（p < 0.01）、受教育程度较低（p < 0.01）、收入较低（p < 0.01）、住房状况较差（p < 0.05）和暴露程度较高（p < 0.05）是 QOL 较差的危险因素（∆R ² = 0.063）。PTSD 症状对 QOL 有负面影响（∆R ² = 0.145），而社会支持对 QOL 有积极影响（∆R ² = 0.016）。然而，社会支持与 PTSD 之间的相互作用削弱了 PTSD 对 QOL 的负面影响（∆R ² = 0.012）。主观支持和支持可用性调节了 PTSD 与 QOL 之间的关联（∆R ² = 0.010）。
主观支持和支持可用性是改善 PTSD 症状地震幸存者 QOL 的更有效策略。
