This study estimated the association between pre-pandemic social network properties and symptoms of posttraumatic stress during the coronavirus disease 2019 (COVID-19) pandemic in South Korea.
We conducted four online mental health surveys during COVID-19 (from March 14, 2020, to December 11, 2021) among individuals enrolled in a community-based cohort study (previously recruited from 2013 to 2018). Among 4060 people interviewed at the pre-pandemic baseline, 2652 individuals (men = 951, women = 1701) who responded to at least one of the four surveys conducted were included. At baseline, each individual's social network, including size and average closeness, was measured in an egocentric way. Post Traumatic Stress Disorder Checklist for DSM-5 (PCL-5) was measured at each survey point. A generalized linear model and a generalized linear mixed model were used after stratified by sex.
Among men, network size was negatively associated with total PCL-5 score (b = -0.42, SE = 0.16, p = 0.002). The magnitude of the association increased over time and was maximal by the 4th survey (b = -0.65, SE = 0.31, p = 0.037). Among women, average closeness was negatively associated with the total PCL-5 score (b = -1.16, SE = 0.37, p = 0.002). In analyses disaggregated by symptom clusters, social networks were associated explicitly with symptoms of intrusion and mood but not with avoidance and arousal symptoms.
In this cohort of adults followed for more than a year during the outbreak of COVID-19 in South Korea, social networks established before the onset of the COVID-19 pandemic had a protective association against developing symptoms of PTSD during the first two years of the pandemic.
本研究旨在评估韩国 2019 年冠状病毒病（COVID-19）大流行期间，大流行前社会网络特征与创伤后应激症状之间的关系。
我们在 COVID-19 期间（2020 年 3 月 14 日至 2021 年 12 月 11 日）进行了四次在线心理健康调查，调查对象是参加一项基于社区的队列研究的个体（先前于 2013 年至 2018 年招募）。在大流行前基线接受访谈的 4060 人中，有 2652 人（男性 951 人，女性 1701 人）至少回应了四次调查中的一次，被纳入本研究。在基线时，以自我为中心的方式测量了每个人的社交网络，包括规模和平均亲密程度。每次调查都测量了创伤后应激障碍检查表第五版（PCL-5）。按照性别分层后，使用广义线性模型和广义线性混合模型进行分析。
在男性中，网络规模与总 PCL-5 评分呈负相关（b=-0.42，SE=0.16，p=0.002）。这种关联的程度随着时间的推移而增加，在第四次调查时达到最大值（b=-0.65，SE=0.31，p=0.037）。在女性中，平均亲密程度与总 PCL-5 评分呈负相关（b=-1.16，SE=0.37，p=0.002）。在按症状群进行的分析中，社会网络与闯入和情绪症状明确相关，但与回避和唤醒症状无关。
在这项对韩国 COVID-19 爆发期间随访超过一年的成年人队列研究中，大流行前建立的社会网络与大流行前两年发生 PTSD 症状有保护关联。
