The aim of this study was to investigate the mediating role of the Big 5 personality traits (extraversion, neuroticism, openness, agreeableness, conscientiousness) in the association between early traumatization and depressive symptoms in early adulthood (20-25-year-olds) in a German population-based sample.
A total of 3176 participants from the German National Cohort (NAKO) baseline with an age between 20 and 25 years were included in this investigation. The sum score of the 9-item-version of the Patient Health Questionnaire was used for assessment of depressive symptoms. A structural equation model was built to test the paths between childhood trauma, Big 5 personality traits and depressive symptoms.
Overall, 10.7 % of the young adult sample had a PHQ-9 sum score of ten or higher. The final mediation model fitted well for young adults. We found evidence for a partial mediating effect of Big 5 personality traits.
We only adjusted for age, sex, and year of data collection and did not include biological factors in the model.
Young adults with early trauma experiences have a risk for developing depressive symptoms in young adulthood. Personality traits, especially neuroticism, partially mediated the association between early trauma and depressive symptoms for young adults and should be recognized in preventive strategies.
本研究旨在探讨大五人格特质（外向性、神经质、开放性、宜人性、尽责性）在德国人群基础样本中，早期创伤与青年早期（20-25 岁）抑郁症状之间的关联中的中介作用。
本研究共纳入了德国国家队列研究（NAKO）基线调查中年龄在 20 至 25 岁之间的 3176 名参与者。采用患者健康问卷的 9 项版本总分评估抑郁症状。构建结构方程模型以检验童年创伤、大五人格特质与抑郁症状之间的路径。
总体而言，10.7%的年轻成年样本 PHQ-9 总分达到或高于 10 分。最终的中介模型对年轻成年人拟合良好。我们发现大五人格特质存在部分中介效应的证据。
我们仅调整了年龄、性别和数据收集年份，并未将生物因素纳入模型。
有早期创伤经历的年轻成年人在青年早期有发展为抑郁症状的风险。人格特质，尤其是神经质，部分中介了早期创伤与年轻成年人抑郁症状之间的关联，应在预防策略中加以认识。
