不确定性忍受力、强迫、焦虑在大学生神经质人格与失眠间的多重中介作用

Multiple mediating effects of intolerance of uncertainty, obsessive-compulsive and generalized anxiety on neuroticism and insomnia in college students

目的考察不确定性忍受力、广泛性焦虑症状、强迫症状在神经质人格和失眠间的多重中介作用。方法采用阿森斯失眠量表,不确定性忍受力量表,宾州忧虑问卷,强迫量表,艾森克人格问卷对405名大学生进行测查。结果大学生失眠[(4.07±2.57)分],不确定忍受力[(72.33±14.42)分],广泛性焦虑[(40.57±10.35)分],神经质[(4.86±3.22)分]和强迫症状[(1.60±1.45)分]呈两两正相关(r=0.18~0.64,P<0.01)。结构方程模型结果显示χ^2/df=2.15,P>0.05;CFI=0.99;GFI=0.99;NFI=0.99;NNFI(TLI)=0.97;RMSEA=0.05,模型拟合较好。中介效应分析显示神经质可直接影响失眠(效应量0.125),可分别通过广泛性焦虑症状(效应量0.082)和强迫症状(效应量0.053)的中介作用影响失眠,也可通过"不确定性忍受力-广泛性焦虑症状"(效应量0.022)和"不确定性忍受力-强迫症状"(效应量0.014)两条链式中介对失眠起作用。结论大学生神经质人格会通过不确定性忍受力、广泛性焦虑症状和强迫症状的多重中介模型影响失眠。

Objective To explore composited multiple mediating effects of intolerance of uneertciinty, generalized anxiety symptoms and obsessive-compulsive symptoms between neuroticism and insomnia. Methods In this study ,405 university students were evaluated using several questionnaires, including Athens Insomnia Scale, Intolerance of Uncertainty Scale, the Penn State Worry Questionnaire and Obsessive-compulsive. Inventory-Revised and Eysenck Personality Questionnaire-Revised Short Scale for Chinese. Results The scores of Athens Insomnia Scale( 4. 07±2. 57), Intolerance of Uncertainty Scale ( 72. 33± 14. 42),The Penn State Worry Questionnaire(40. 57± 10. 35), Compulsive Activity Checklist-Revised( 1.60± 1. 45) and Eysenck Personality Questionnaire-Revised Short Seal(4. 86±3. 22) were positively correlated with each other(r=0. 18~0. 64,P<0. 01). Model fit indices in SEM were X^2/df= 2.15,P>0. 05;CFI = 0. 99;GFI =0. 99;NFI = 0. 99;NNFI( TLI)= 0. 97;RMSEA = 0. 05. The results indicated that neuroticism directly affected insomnia ( effect size 0. 125), neuroticism affects insomnia through generalized anxiety symptoms (effect size 0. 082) and obsessive-compulsive symptoms ( effect size 0. 053) respectively. Thus, generalized anxiety symptoms and obsessive-compulsive symptoms were parallel mediators. Neuroticism affects generalized anxiety symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 022). And neuroticism affected obsessive-compulsive symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 014). Conclusion The neuroticism personality of university students can influence insomnia through the multiple mediation model of intolerance of uncertainty, generalized anxiety symptoms and obsessive-compulsive symptoms.
