Descriptive statistics for study variables.

Background
Childhood trauma has been identified as a significant risk factor for adverse mental health outcomes and increased suicide risk. However, the mechanisms by which stress-related variables, such as stress appraisal, influence this pathway remain unclear. The current study sought to: (1) investigate whether childhood trauma was associated with mental health outcomes (depression, anxiety), suicide risk factors (defeat, entrapment), and stress related outcomes (stress appraisal, perceived stress) in adulthood and (2) determine whether stress appraisal and perceived stress mediate the effects of childhood trauma on mental health outcomes and suicide risk factors.
Method
273 participants were recruited to an online prospective study that consisted of two sessions with a one-week interval. In session 1, the childhood trauma questionnaire was completed. In session 2, participants completed measures assessing the level of depression, anxiety, defeat, entrapment, stress appraisal and perceived stress over the preceding week.
Results
Analyses found that childhood trauma was significantly associated with higher scores on depression, anxiety, defeat, entrapment, stress appraisal and perceived stress. Childhood trauma also had indirect effects on depression, anxiety, defeat, and entrapment through stress appraisal and perceived stress.
Conclusion
These findings underscore the enduring impact of childhood trauma on mental health outcomes and suicide risk in adulthood, mediated through its influence on stress appraisals and perceptions of stress encountered in daily life. These underlying mechanisms are critical for informing the development of future interventions.

研究背景
童年创伤已被证实是不良心理健康结局及自杀风险升高的重要危险因素。然而，压力评估（stress appraisal）等应激相关变量如何作用于这一发病通路的具体机制仍不明确。本研究旨在达成两个目标：（1）探究成年期童年创伤与心理健康结局（抑郁、焦虑）、自杀危险因素（挫败感、被困感）及应激相关结局（压力评估、感知压力）之间的关联；（2）明确压力评估与感知压力是否在童年创伤对心理健康结局及自杀危险因素的影响中起到中介作用。
研究方法
本研究为线上前瞻性研究，共招募273名被试，实验分为两个阶段，间隔时长为一周。第一阶段中，被试填写童年创伤问卷。第二阶段中，被试完成针对过去一周内抑郁、焦虑、挫败感、被困感、压力评估及感知压力水平的测评量表。
研究结果
分析结果显示，童年创伤与抑郁、焦虑、挫败感、被困感、压力评估及感知压力的更高得分呈显著相关。此外，童年创伤可通过压力评估与感知压力对抑郁、焦虑、挫败感及被困感产生间接影响。
研究结论
本研究结果证实，童年创伤对成年期心理健康结局及自杀风险存在持久影响，这一效应可通过其对日常压力评估与压力感知的作用实现中介。上述潜在机制可为未来干预措施的开发提供重要理论依据。
