The Peritraumatic Distress Inventory (PDI) is a well-known self-report questionnaire indexing the distress experienced during and shortly after a most stressful or traumatic event. Although sociodemographic factors contributing to peritraumatic distress have been previously investigated, no research has examined the nature and severity of peritraumatic distress reactions in a non-clinical, community sample as a function of age. An international sample of 5621 adult participants were grouped according the World Health Organization's age stratification protocol. Mean scores and item endorsement on the PDI were compared across groups with respect to their worst experience of the COVID-19 pandemic. A significant between-group difference was found, F(55,615) = 30.74, p < 0.001, n = 0.027 whereby participants aged 18-39 years old reported the highest levels of peritraumatic distress. This group also endorsed a higher proportion of items on the PDI's two main factors (emotional distress and physical reactions), and were more likely to endorse feelings of helplessness, than older participants. It appears that severity of peritraumatic distress during the pandemic has affected younger people the most. Results are discussed in light of clinical implications.
创伤后应激障碍量表（PDI）是一种广为人知的自我报告问卷，用于评估在最紧张或创伤性事件期间和之后经历的痛苦。尽管先前已经研究了导致创伤后痛苦的社会人口因素，但没有研究在非临床、社区样本中，根据年龄检查创伤后痛苦反应的性质和严重程度。根据世界卫生组织的年龄分层方案，将 5621 名成年参与者的国际样本分为不同组。根据他们对 COVID-19 大流行的最严重经历，比较了 PDI 各项目的平均得分和项目认可情况。发现了显著的组间差异，F(55,615)=30.74，p<0.001，n=0.027，年龄在 18-39 岁的参与者报告了最高水平的创伤后痛苦。这一组在 PDI 的两个主要因素（情绪困扰和身体反应）上的项目比例更高，并且比年龄较大的参与者更容易感到无助。似乎在大流行期间，创伤后痛苦的严重程度对年轻人的影响最大。结果根据临床意义进行了讨论。
