Abstract

Background

This study aimed to investigate the association of the grit scale, a personality trait characterized by perseverance and passion, with both the presence and the severity of insomnia in the Korean adult population.

Methods

A nationwide population-based cross-sectional survey was conducted through face-to-face interviews using structured questionnaires between September and December 2018 in Korea. Grit was assessed by using the 8-item Short Grit Scale. Participants were categorized into insomnia and non-insomnia groups based on a threshold of 10 on the Insomnia Severity Index (ISI). The association between girt and insomnia was analyzed using multiple linear regression and multivariable logistic regression, controlling for sociodemographic factors, lifestyles, and comorbidities.

Results

A total of 2453 participants (49.9 % male; aged 19–92 years) were enrolled in the study. Individual grit scores ranged from 1.75 to 5.00 points (mean [SD], 3.27 [0.42]), and insomnia was present in 16.5 % of the population. The insomnia group exhibited lower grit score compared to the non-insomnia group (3.11 [0.40] vs. 3.30 [0.42], p < 0.001, Cohen's d = 0.46). Grit was negatively associated with ISI scores (β = −0.15, 95 % CI = −0.19, −0.11, p < 0.001) and with having insomnia (OR 0.40, 95 % CI = 0.30, 0.55, p < 0.001), after controlling for covariates.

Conclusions

Individuals with higher grit were less likely to have insomnia. Clinicians should consider personality traits, such as grit, in the evaluation and the management of insomnia.

勇气与失眠之间的关系：一项基于人口的研究。

研究背景本研究旨在调查韩国成年人群中的勇气量表（一种以毅力和激情为特征的人格特质）与失眠的存在和严重程度之间的关联：2018年9月至12月期间，在韩国使用结构化问卷通过面对面访谈的方式开展了一项全国范围的人群横断面调查。采用 8 项短式勇气量表对勇气进行评估。根据失眠严重程度指数（ISI）10的临界值，将参与者分为失眠组和非失眠组。在控制了社会人口学因素、生活方式和合并症的情况下，采用多元线性回归和多变量逻辑回归分析了克特与失眠之间的关系：共有 2453 名参与者（49.9% 为男性，年龄在 19-92 岁之间）参加了研究。个人勇气得分从 1.75 分到 5.00 分不等（平均值[SD]，3.27 [0.42]），16.5%的人患有失眠症。失眠组的勇气得分低于非失眠组（3.11 [0.40] vs. 3.30 [0.42]，P 结论：失眠组的勇气得分高于非失眠组：勇气越高的人越不容易失眠。临床医生在评估和治疗失眠症时应考虑人格特质，如勇气。

期刊介绍： Sleep Medicine aims to be a journal no one involved in clinical sleep medicine can do without. A journal primarily focussing on the human aspects of sleep, integrating the various disciplines that are involved in sleep medicine: neurology, clinical neurophysiology, internal medicine (particularly pulmonology and cardiology), psychology, psychiatry, sleep technology, pediatrics, neurosurgery, otorhinolaryngology, and dentistry. The journal publishes the following types of articles: Reviews (also intended as a way to bridge the gap between basic sleep research and clinical relevance); Original Research Articles; Full-length articles; Brief communications; Controversies; Case reports; Letters to the Editor; Journal search and commentaries; Book reviews; Meeting announcements; Listing of relevant organisations plus web sites.
