人们对潜在创伤事件的反应不同。为了探索自然灾害后创伤后应激症状（PTSS）的慢性和延迟轨迹的预测因素，我们分析了2011年2月新西兰基督城发生6.3级地震后收集的412名居民的心理测量数据。来自不同社会经济地位（SES）和地震影响水平的郊区的参与者在地震后4-7个月（时间1; N = 600）和地震后10-11个月（时间2; N = 412）完成了挨家挨户的调查。调查包括急性应激障碍量表、患者健康问卷的9项抑郁子量表和广泛性焦虑障碍-7量表，沿着单项变量测量，包括余震焦虑和家庭紧张。Hobfoll的资源保护理论被用来指导数据解释。高水平的抑郁，比值比（OR）= 1.24，和焦虑，OR = 1.24，在时间1显着预测成员的慢性轨迹。症状延迟发作的预测因素包括随着时间的推移，余震焦虑增加，OR = 1.29，家庭紧张，OR = 1.35，以及生活在一个被定义为低，OR = 5.36，或中等，OR = 11.39，SES的地区。结果突出了PTSS升高的风险因素和个人可以用来抵消威胁损失的资源。这些发现对服务提供者、机构和公众都有影响。
People respond differently to potentially traumatic events. To explore predictors of a chronic and delayed trajectory of posttraumatic stress symptoms (PTSS) after a natural disaster, we analyzed psychometric data collected from 412 residents of Christchurch, New Zealand after a 6.3 magnitude earthquake struck in February 2011. Participants from suburbs with different levels of socioeconomic status (SES) and earthquake impact completed a door-to-door survey 4-7 months after the earthquake (Time 1; N = 600) and again 10-11 months after the earthquake (Time 2; N = 412). The survey included the Acute Stress Disorder Scale, the Patient Health Questionnaire's nine-item Depression subscale, and the Generalized Anxiety Disorder-7 scale, along with single-item measures of variables including aftershock anxiety and family tension. Hobfoll's conservation of resources theory was used to guide data interpretation. High levels of depression, odds ratio (OR) = 1.24, and anxiety, OR = 1.24, at Time 1 significantly predicted membership in the chronic trajectory. Predictors of a delayed onset of symptoms included increased aftershock anxiety, OR = 1.29, and family tension, OR = 1.35, over time, as well as living in an area defined as being of low, OR = 5.36, or medium, OR = 11.39, SES. Results highlight risk factors for elevated PTSS and resources that individuals can use to offset threatened loss. These findings have implications for service providers, agencies, and the public.
