摘要目的:调查大深度饱和潜水训练期间保障人员的睡眠及应激状态，为任务期间相关人员的心理支持提供参考。方法:采用匹兹堡睡眠质量指数量表(PSQI)和斯坦福急性应激反应问卷(SASRQ)对参加年度大深度饱和潜水训练保障任务的某舰船员61人进行测评。结果:PSQI总分为(12.82±3.55)分，高于7分的有57人，占93.44%。不同年龄组成员的得分差异有统计学意义，其中20~29岁组得分最高( F＝3.573， P＝0.035)。不同岗位保障人员的日间功能分量表得分和PSQI总分差异有统计学意义，潜水员得分显著低于其他岗位人员( F＝4.945， P＝0.010； F＝3.806， P＝0.029)。保障人员SASRQ评分为(36.87±14.84)分，应激处于重度程度的为5人，阳性项目数超过3项的为16人。舰艇人员应激水平与睡眠质量中除"助眠药物使用"条目之外的其他条目呈正相关。 结论:大深度饱和潜水训练期间应同时关注保障人员的心理状态，确保训练任务全程的安全稳定。

abstractsObjective:To investigate the sleep and stress state of support personnel during deep saturation diving training so as to provide reference for psychological support for such personnel on diving mission.Methods:The Pittsburgh sleep quality index (PSQI) and Stanford acute stress response questionnaire (SASRQ) were used to evaluate 61 sailors from a warship in their annual task of supporting deep saturation diving training.Results:The total score of PSQI was 12.82±3.55, with 57 people higher than 7 points, accounting for 93.44%. There were significant differences in PSQI scores among different age groups, and that of the group aged 20-29 was the highest ( F=3.573, P=0.035). The scores of daytime functional and PSQI of support personnel at different posts were significantly different, and the scores in the posts directly supporting divers are significantly lower than those in the other two kinds of posts ( F=4.945, P=0.010; F=3.806, P=0.029). The average stress level of the crew was 36.87±14.84, among them, 5 sailors were under severe stress, and 16 sailors had more than 3 positive items. Among all the investigated crew members, there was a positive correlation between the stress test score and sleep quality except for the item of "using sleeping aids" . Conclusion:Attention should be paid to the psychological state of support personnel during the whole process of saturation deep diving in order to keep the training safe and smooth.
