Research on the relationship between personality traits and sleep problems is crucial, as it informs interventions designed to improve mental health and overall well-being. This meta-analytic review aimed to examine the associations between the Big Five personality traits and both subjective sleep quality and insomnia severity. Another objective was to compare the mean scores of personality traits in individuals with insomnia and healthy controls.
Three international databases were systematically searched for articles published in English between January 1990 and November 2022 (PROSPERO-CRD42022378352). Due to the observed heterogeneity, pooled estimates of correlations and standardized mean differences were calculated using the random-effects method. Meta-regression and subgroup analyses were performed to identify potential moderators.
The estimates derived from 51 studies (involving nearly 31,000 participants from 20 countries) indicated that higher scores of neuroticism and lower scores of extraversion, openness, agreeableness, and conscientiousness were significantly associated with poor sleep quality (r = - 0.05 to 0.31). With the exception of openness, all other personality traits were significant correlates of insomnia. The meta-regressions revealed that population type, geographic region, age, sample size, sample ratio, quality of study, and year of study served as significant moderators.
Despite the significant associations between most personality traits and sleep problems, the heterogeneous estimates were influenced by several moderators. Addressing these moderators can provide researchers with deeper insights into personalized interventions aimed at improving sleep quality across diverse populations. These significant associations also underscore the importance of incorporating personality assessments in clinical settings for individuals experiencing sleep disturbances.
研究人格特质与睡眠问题之间的关系至关重要，因为这为旨在改善心理健康和整体幸福感的干预措施提供了依据。本荟萃分析旨在研究大五人格特质与主观睡眠质量和失眠严重程度之间的关联。另一个目标是比较失眠患者和健康对照组的人格特质平均得分。
系统检索了三个国际数据库，以查找1990年1月至2022年11月期间发表的英文文章（PROSPERO-CRD42022378352）。由于观察到存在异质性，使用随机效应方法计算相关性和标准化平均差异的合并估计值。进行了元回归和亚组分析以确定潜在的调节因素。
来自51项研究（涉及来自20个国家的近31000名参与者）的估计表明，神经质得分较高以及外向性、开放性、宜人性和尽责性得分较低与睡眠质量差显著相关（r = -0.05至0.31）。除开放性外，所有其他人格特质都是失眠的显著相关因素。元回归显示，人群类型、地理区域、年龄、样本量、样本比例、研究质量和研究年份是显著的调节因素。
尽管大多数人格特质与睡眠问题之间存在显著关联，但异质性估计受到几个调节因素的影响。解决这些调节因素可以为研究人员提供更深入的见解，以便针对不同人群制定旨在改善睡眠质量的个性化干预措施。这些显著关联也强调了在临床环境中对睡眠障碍患者进行人格评估的重要性。
