军人群体睡眠质量和正念的相关性研究

Study on correlation between sleep quality and mindfulness in military personnel

目的探讨军人群体中睡眠质量与正念的相关性及正念水平能否预测睡眠质量。方法使用网络问卷的形式,采用匹兹堡睡眠质量指数(pittsburgh sleep quality index,PSQI)量表、正念注意觉知量表(mindful attention awareness scale,MAAS)及抑郁-焦虑-压力量表(depression anxiety stress scales,DASS),分别于2021年4和6月对火箭军某部官兵及海军某部官兵进行调查,使用相关分析及回归分析探讨睡眠质量和正念水平的关系。结果火箭军某部官兵的PSQI得分[M(_(25),P_(75))]为6(3,9)分,睡眠质量较差者占32.04%(58人);海军某部官兵的PSQI总得分[M(_(25),P_(75))]为5(3,8)分,睡眠质量较差者占27.47%(50人)。海军某部官兵及火箭军某部官兵的MAAS得分[M(_(25),P_(75))]一致,均为4.87(4.13,5.53)分。不同军种、年龄组PSQI总分、MAAS及DASS各维度比较,差异均无统计学意义(均P>0.05);高学历组(本科及以上)的正念水平较低(U=10499.5,P<0.05),其余变量差异无统计学意义(均P>0.05);不同性别DASS-焦虑得分差异无统计学意义(P>0.05),女性的PSQI、DASS-抑郁及DASS-压力得分更高,MAAS得分更低(均P<0.05)。PSQI与MAAS呈负相关(r_(s)=-0.431,P<0.01),与DASS各维度均呈正相关(r_(s)=0.562、0.512、0.545,均P<0.01)。回归分析显示,在纳入人口学变量、DASS的抑郁、焦虑及压力维度后,正念水平对睡眠质量的预测能力差异无统计学意义(β=-0.067,P>0.05)。结论正念水平与睡眠质量相关,但不能预测睡眠质量。

Objective To explore the relationship between sleep quality and mindfulness in military personnel,and whether mindfulness could predict sleep quality.Methods By the online questionnaires,the officers and soldiers of a rocket army unit and a navy unit were investigated with the Pittsburgh sleep quality index(PSQI),mindful attention awareness scale(MAAS),and depression anxiety stress scales(DASS)in April and June 2021 respectively.Correlation and regression analysis were used to explore the relationship between mindfulness and sleep quality.Results The total PSQI score[M(_(25),P_(75))]of officers and soldiers in a rocket army unit was 6(3,9)points,and those with poor sleep quality accounted for 32.04%(58 people).The total PSQI score[M(_(25),P_(75))]of officers and soldiers in a navy unit was 5(3,8)points,and those with poor sleep quality accounted for 27.47%(50 people).The MAAS scores[M(_(25),P_(75))]of officers and soldiers in rocket army unit and navy unit were consistent,both were 4.87(4.13,5.53)points.The differences on total PSQI score,MAAS and various dimension of DASS were not statistically significant between different military services and age groups(all P>0.05).The higher education group(bachelor’s degree and above)had lower level of mindfulness(U=10499.5,P<0.05),and the differences in other variables were not statistically significant(all P>0.05).There was no statistically significant difference in score of DASS-anxiety between sex groups(P>0.05).Females had higher scores of PSQI,DASS-depression and DASS-stress,and lower MAAS score(all P<0.05).PSQI score was negatively related with MAAS score(r_(s)=-0.431,P<0.01),and positively correlated with various dimensions of DASS(r_(s)=0.562,0.512,0.545,all P<0.01).The regression analysis showed mindfulness could not significantly predict sleep quality after including demographic factors,and depression,anxiety and stress dimensions of DASS(β=-0.067,P>0.05).Conclusion Mindfulness is correlated with sleep quality,but could not predict sleep quality.
