摘要

目的

考察知觉压力对男性军人失眠严重程度的影响，并探讨抑郁在其中的中介作用和正念在其中的调节作用。

方法

于2021年3月应用知觉压力量表(Perceived Stress Scale

PSS)、失眠严重程度量表(Insomnia Severity Index

ISI)、抑郁自评量表(Self-Rating Depression Scale

SDS)和五因素正念量表(Five Facet Mindfulness Questionnaire

FFMQ)对内地陆军某部1 321名男性军人进行调查。采用Pearson相关分析考察男性军人知觉压力、失眠严重程度、抑郁及正念之间的相关性，采用PROCESS程序探讨抑郁的中介和正念的调节效应。

结果

① 男性军人失眠发生率为11.36%，其中，亚失眠状态、临床失眠、严重失眠发生率分别为8.86%、2.12%、0.38%；抑郁症状发生率为15.52%，其中，轻、中、重度抑郁发生率分别为9.16%、6.13%、0.23%。②PSS评分与ISI评分显著正相关(

=0.43

0.01)，SDS评分与PSS、ISI评分显著正相关(

=0.70、0.42

0.01)，FFMQ评分与PSS、SDS、ISI评分显著负相关(

=-0.39、-0.39、-0.17

0.01)。③抑郁在知觉压力与男性军人失眠严重程度之间起部分中介作用，占总效应比例为37.21%。④正念调节了知觉压力对抑郁的影响(

=-0.11

0.01)以及知觉压力对失眠严重程度的影响(

=-0.05

0.05)，与低正念水平相比，高正念水平缓解了知觉压力对抑郁和失眠严重程度的不良作用。

结论

知觉压力通过抑郁情绪影响男性军人的失眠严重程度，正念可以缓冲知觉压力对抑郁和失眠严重程度的影响。开展正念训练可能有助于减少知觉压力军人的抑郁情绪及提升睡眠质量。

Abstract

Objective

To explore the effect of perceived stress on insomnia severity among male soldiers

and examine the mediating effect of depression and the moderating effect of mindfulness.

Methods

A sample of 1 321 male soldiers from a unit of the army were investigated with Perceived Stress Scale (PSS)

Insomnia Severity Index (ISI)

Self-Rating Depression Scale (SDS) and Five Facet Mindfulness Questionnaire (FFMQ) during March 2021. Pearson correlation analysis was employed to analyze the correlation of perceived stress

insomnia severity

depression and mindfulness. PROCESS program was adopted to investigate the mediating role of depression and moderating role of mindfulness.

Results

① The incidence rate of insomnia was 11.36% among the male soldiers. The prevalence rate of subthreshold insomnia was 8.86%

of clinical insomnia (moderate severity) was 2.12%

and of clinical insomnia (severe) was 0.38%. The prevalence

rate of depression was 15.52% among them. And the prevalence rate of mild depression was 9.16%

of moderate depression was 6.13%

and of major depression was 0.23%. ②PSS score had significant positive correlation with ISI score (

=0.43

0.01)

and SDS score was positively correlated with both PSS and ISI scores (

=0.70

0.42

0.01). FFMQ score was negatively correlated with PSS

SDS and ISI scores (

=-0.39

-0.39

-0.17

0.01). ③The relationship between perceived stress and insomnia severity was partially mediated by depression

accounting for 37.21% of the total effect. ④The effect of perceived stress on depression (

=-0.11

0.01) and effect of perceived stress on insomnia severity (

=-0.05

0.05) were both moderated by mindfulness. Compared with low level of mindfulness

high level of mindfulness could alleviate the adverse impacts of perceived stress on both depression and insomnia severity.

Conclusion

Perceived stress affects insomnia severity through depression

and mindfulness can mitigate the effects of perceived stress on both depression and insomnia severity. Mindfulness training may help to reduce depression and improve sleep quality of male soldiers.
