Abstract：Objective To investigate the sleep quality and perceived stress of military aircrews and the moderating effects of coping styles.Methods The Pittsburgh Sleep Quality Index(PSQI)scale,the Perceived Stress Scale(PSS),and the Simplified Coping Style Questionnaire(SCSQ)were employed to conduct a questionnaire survey among 102 military aircrews.The results of the survey were subjected to descriptive statistical analysis,correlation analysis,and moderation effect analysis on 98 valid questionnaires.Results The total score of PSQI for military aircrews was(7.95±3.03)points,and 39.80%of these aircrews(39/98)had sleep disorders(PSQI≥8 points).The total score of PSS was(25.85±8.15)points,with 34.69%(34/98)experiencing high levels of stress and 6.12%(6/98)experiencing extremely high levels of stress.The sleep quality index was positively correlated with perceived stress and negative coping(r/rs=0.909,0.901,all P＜0.001),while positive coping was negatively correlated with the sleep quality index,perceived stress,and negative coping(r/rs=-0.865,-0.911,-0.898,all P＜0.001).Positive coping styles played a moderating role in the relationships between perceived stress and sleep quality(P＜0.001),while negative coping styles had no moderating effect(P=0.676).Conclusion Military aircrews have suboptimal sleep quality.The greater the stress,the poorer the sleep quality.Positive coping styles can mitigate the negative impact of stress on sleep quality.
