Data Sheet 1_Understanding the interplay between stress, anxiety, and depression and their impact on health in traffic police officers.docx

BackgroundTraffic police officers are frequently exposed to stress, anxiety, and depression, which adversely impact their health. This study hypothesized that these factors influence the hormonal, muscular, digestive, and cognitive systems of traffic police officers.
MethodsThe sample comprised 146 traffic police officers (42 women and 104 men) aged 30 to 38. Gender differences in symptoms were examined, and model fit was assessed using indicators such as chi-square, comparative fit index, root mean square error of approximation (RMSEA), and standardized root means residual (SRMR).
ResultsGender differences were observed, with women reporting more significant issues related to muscular (t = 2.77, p = .003), hormonal (t = 2.29, p = .001), and cognitive symptoms (t = 1.37, p = .08). The models demonstrated a good fit, particularly in the model examining digestive symptoms (CFI.95, RMSEA.06 (.05 -.08), SRMR.04).
ConclusionsThe findings indicate a substantial impact of stress, anxiety, and depression on traffic police officers’ health. Psychological support and monitoring are recommended at traffic police stations.
Practical and academic contributionThis research offers essential academic contributions by advancing understanding of the psychophysiological effects of stress, anxiety, and depression in high-stress occupations, using predictive modeling. Practically, the findings support the development of targeted mental health interventions and preventive strategies tailored to traffic police officers, contributing to improved occupational health and job performance.

研究背景
交通警察常暴露于压力、焦虑与抑郁情绪之中，此类负面情绪会对其身体健康造成不良影响。本研究假设上述情绪因素会对交通警察的内分泌系统、肌肉系统、消化系统以及认知系统产生影响。

研究方法
本研究纳入146名交通警察作为研究对象，其中女性42名、男性104名，年龄介于30至38岁之间。本研究对症状的性别差异进行了检验，并采用卡方检验（chi-square）、比较拟合指数（comparative fit index, CFI）、近似均方根误差（root mean square error of approximation, RMSEA）以及标准化残差均方根（standardized root means residual, SRMR）等指标对模型拟合度进行评估。

研究结果
本研究观察到显著的性别差异：女性在肌肉系统（t=2.77，p=0.003）、内分泌系统（t=2.29，p=0.001）以及认知症状（t=1.37，p=0.08）方面报告的问题更为严重。各模型均展现出良好的拟合效果，其中针对消化系统症状的模型拟合效果尤为出色（CFI=0.95，RMSEA=0.06，95%置信区间0.05-0.08，SRMR=0.04）。

研究结论
本研究结果表明，压力、焦虑与抑郁情绪对交通警察的健康具有显著负面影响。因此建议在交警执勤单位开展心理支持服务与健康监测工作。

实践与学术贡献
本研究通过预测建模方法，加深了学界对高压力职业群体中压力、焦虑与抑郁情绪所产生的心理生理影响的认知，具备重要的学术价值。在实践层面，本研究结果可为针对交通警察群体的个性化心理健康干预方案与预防策略的开发提供支撑，进而助力提升职业健康水平与工作绩效。
