Although trauma exposure is universally prevalent, the ways in which individuals respond to potentially traumatic events vary. Between-country differences have been identified as affecting the development and manifestation of transdiagnostic psychological symptoms, but it remains unclear how stress and trauma-related transdiagnostic symptoms and risk patterns differ based on geographic region. To explore whether there are distinct classes of stress and trauma-related transdiagnostic symptoms and to determine predictors of class membership in a global sample. Participants ( = 8675) from 115 different countries were recruited online between 2020-2022 and completed the Global Psychotrauma Screen, which assesses stress and trauma exposure, related symptoms, and risk factors. A latent class analysis (LCA) was used to identify classes of stress and trauma-related symptoms per world region (African States, Asia-Pacific States, Eastern European States, Latin American and Caribbean States, Western European and Other States, and North America) and the total sample. Likelihood of class membership was assessed based on demographics, characteristics of the potentially traumatic event, and potential risk factors across the world regions. Similar class compositions were observed across regions. A joint latent class analysis identified three classes that differed by symptom severity (i.e. high, moderate, low). Multinomial logistic regression analyses revealed several factors that conferred greater risk for experiencing higher levels of symptoms, including geographic region, gender, and lack of social support, among others. Stress and trauma-related symptoms seem to be similarly transdiagnostic across the world, supporting the value of a transdiagnostic assessment.
虽然创伤暴露普遍存在，但个体对潜在创伤事件的反应方式有所不同。国家间的差异已被确定为影响跨诊断心理症状的发展和表现，但仍不清楚基于地理区域，应激和创伤相关的跨诊断症状和风险模式有何不同。为了探索是否存在不同类别的应激和创伤相关的跨诊断症状，并确定全球样本中类别的预测因素。2020 年至 2022 年间，通过在线招募了来自 115 个不同国家的参与者（ = 8675 人），并完成了全球心理创伤筛查，该筛查评估了应激和创伤暴露、相关症状和风险因素。使用潜在类别分析（LCA）按世界区域（非洲国家、亚太国家、东欧国家、拉丁美洲和加勒比国家、西欧和其他国家以及北美）和总样本识别应激和创伤相关症状的类别。根据世界区域的人口统计学特征、潜在创伤事件的特征以及潜在风险因素，评估类别的归属可能性。在各个区域都观察到了相似的类别组成。联合潜在类别分析确定了三个症状严重程度不同的类别（即高、中、低）。多项逻辑回归分析显示，包括地理位置、性别和缺乏社会支持在内的几个因素会增加出现更高水平症状的风险。应激和创伤相关症状在全球范围内似乎具有相似的跨诊断特征，这支持了跨诊断评估的价值。
