Abstract

BACKGROUND

Insomnia is a major public health issue worldwide. An association between neuroticism and insomnia has been widely confirmed, but its psychological mechanisms are unclear.

METHODS

A total of 1790 online participants completed the Big Five Personality Inventory, Athens Insomnia Scale, Chinese version of the Mind Wandering Questionnaire, and Chinese version of the Nolen-Hoeksema Ruminative Responses Scale. The relationship between neuroticism and insomnia was analyzed using correlation and mediation analyses, and the mediating effect of mind wandering and rumination symptoms was investigated.

RESULTS

Research findings indicated significant positive correlations (r > 0.464, p < 0.001) among neuroticism, mind wandering, symptom rumination, and insomnia. Furthermore, mediation analysis revealed that neuroticism exerted a significant direct effect on insomnia and an indirect effect through mind wandering and symptom rumination (estimate = 0.372, SE = 0.031, p < 0.001). Additionally, both mind wandering (estimate = 0.361, SE = 0.038, p < 0.001) and symptom rumination (estimate = 0.759, SE = 0.046, p < 0.001) independently mediated the relationship between neuroticism and insomnia.

LIMITATIONS

Cross-sectional studies are difficult to establish causal relationships between study variables, and self-report questionnaire assessments have some recall bias, selection bias.

CONCLUSION

Mind wandering and symptom rumination induced by neuroticism were risk factors for insomnia. Interventions targeting mind wandering and symptom rumination may block this pathway, providing new insights for the development of insomnia interventions.

摘要

背景

失眠是全球主要的公共卫生问题。神经质与失眠之间的关联已得到广泛证实，但其心理机制尚不清楚。

方法

共有1790名在线参与者完成了大五人格量表、雅典失眠量表、中文版的思维游荡问卷和中文版的诺伦 - 霍克西玛反刍反应量表。使用相关性分析和中介分析来分析神经质与失眠之间的关系，并研究思维游荡和反刍症状的中介作用。

结果

研究结果表明，神经质、思维游荡、症状反刍和失眠之间存在显著的正相关（r > 0.464，p < 0.001）。此外，中介分析显示，神经质对失眠有显著的直接影响，并通过思维游荡和症状反刍产生间接影响（估计值 = 0.372，标准误 = 0.031，p < 0.001）。此外，思维游荡（估计值 = 0.361，标准误 = 0.038，p < 0.001）和症状反刍（估计值 = 0.759，标准误 = 0.046，p < 0.001）均独立介导了神经质与失眠之间的关系。
