The goal of this paper is to examine the social network effects on post-traumatic sdress disorder (PTSD) in female North Korean immigrants who entered South Korea in 2007. Specifically, it attempts to verify if the density and composition of networks make a difference after controlling for the network size.
A multivariate logistic regression is used to probe the effects of social networks using the North Korean Immigrant Panel data set. Because the data set had only completed its initial survey when this paper was written, the analysis was cross-sectional.
The size of the support networks was systematically related to PTSD. Female North Korean immigrants with more supporting ties were less likely to develop PTSD, even after controlling for other risk factors (odds-ratio for one more tie was 0.8). However, once we control for the size of the network, neither the density nor the composition of the networks remains statistically significant.
The prevalence of the PTSD among female North Korean immigrants is alarmingly high, and regardless of the characteristics of supporting network members, the size of the supporting networks provides substantial protection. This implies that a simple strategy that focuses on increasing the number of supporting ties will be effective among North Korean immigrants who entered South Korea in recent years.
本文旨在研究社交网络对2007年进入韩国的朝鲜女性移民创伤后应激障碍（PTSD）的影响。具体而言，它试图验证在控制网络规模后，网络的密度和构成是否会产生影响。
使用朝鲜移民面板数据集，通过多元逻辑回归来探究社交网络的影响。由于在撰写本文时该数据集仅完成了初始调查，因此分析为横断面分析。
支持网络的规模与创伤后应激障碍有系统性关联。即使在控制了其他风险因素后，拥有更多支持关系的朝鲜女性移民患创伤后应激障碍的可能性也较小（每多一个关系的优势比为0.8）。然而，一旦我们控制了网络规模，网络的密度和构成在统计上均不再显著。
朝鲜女性移民中创伤后应激障碍的患病率高得惊人，并且无论支持网络成员的特征如何，支持网络的规模都提供了实质性的保护。这意味着，对于近年来进入韩国的朝鲜移民，一个侧重于增加支持关系数量的简单策略将是有效的。
