作者考察了社会原因和社会选择对社会支持知觉和心理痛苦之间关系的解释。数据来自墨西哥557名自然灾害受害者的样本。结构方程模型分析表明，社会原因(更多的社会支持导致较少的创伤后应激障碍[PTSD])解释了灾难后早期阶段，即影响后6至12个月的支持与痛苦的关系。在研究的中点(12个月和18个月)，这两种因果机制都成为重要的路径。只有社会选择(更多的创伤后应激障碍导致更少的社会支持)在事件发生后18至24个月解释了支持到痛苦的关系。灾难的人际和社会动态可能解释了为什么这两种截然不同的因果机制会随着时间的推移而出现。
The authors examined social causation and social selection explanations for the association between perceptions of social support and psychological distress. Data came from a sample of 557 victims of natural disaster in Mexico. Structural equation modeling analyses indicated that social causation (more social support leading to less posttraumatic stress disorder [PTSD]) explained the support-to-distress relationship in the earlier postdisaster phase, 6 to 12 months after the impact. Both causal mechanisms emerged as significant paths in the midpoint of the study (12 and 18 months). Only social selection (more PTSD leading to less social support) accounted for the support-to-distress relationship at 18 to 24 months after the event. Interpersonal and social dynamics of disasters may explain why these two contrasting causal mechanisms emerged over time.
