【摘要】 目的 探讨民航飞行学员压力知觉、反刍思维、睡眠质量与社会支持的关系。方法 2025年5月采用方便取样法对308名理论学习阶段的飞行学员进行施测，采用中文版压力知觉量表、匹茨堡睡眠质量指数（PSQI）、反刍思维量表以及社会支持评定量表进行调查。结果 (1)飞行学员反刍思维得分在压力知觉得分与PSQI之间存在部分中介效应，中介效应比例为50.59%；(2)社会支持得分在压力知觉与反刍思维得分（β=-0.033,t=-9.675,P<0.001）、压力知觉与PSQI(β=-0.005,t=-4.206,P<0.001)、反刍思维与PSQI(β=-0.008,t=-4.228,P<0.001)间起调节作用。结论 压力知觉可通过反刍思维正向预测PSQI得分（即负向预测睡眠质量）；民航飞行学员的高社会支持可以显著减轻压力知觉对睡眠质量的影响。更多还原

【Abstract】 Objective Investigating the relationship between civil aviation cadets’ perceived stress, rumination, sleep quality and social support. Methods In May 2025, a convenience sampling approach was employed to administer assessments to 308 flight cadets during their theoretical training phase. The investigation utilised the Chinese version of the perceived stress scale, the Pittsburgh sleep quality index(PSQI), the rumination scale, and the social support rating scale. Results(1)Rumination scores partially mediated the relationship between perceived stress and PSQI scores, accounting for 50.59% of the variance.(2)Social support scores moderated the relationship between perceived stress and rumination scores(β=-0.033, t=-9.675, P<0.001), perceived stress and PSQI(β=-0.005, t=-4.206, P<0.001), and rumination and PSQI(β=-0.008, t=-4.228, P<0.001). Conclusion Perceived stress can positively predict PSQI scores through rumination(i.e., negatively predicting sleep quality). High social support significantly mitigates the impact of perceived stress on sleep quality among these trainees.更多还原
