Abstract:
Objective: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.
