While the association between personality traits and insomnia has been confirmed, the longitudinal relationship between them remains unclear.
This is a 4-year longitudinal cohort study conducted among rural community residents ( = 482) in Shandong Province, China.
This study found that neuroticism ( = 0.175, < 0.001), extraversion ( = -0.146, < 0.001), and conscientiousness ( = -0.168, < 0.001) at baseline had statistically significant longitudinal associations with insomnia at follow-up. In addition, insomnia at baseline had statistically significant longitudinal correlations with neuroticism ( = 0.142, < 0.01), extraversion ( = -0.209, < 0.001), and agreeableness ( = -0.122, < 0.01) at follow-up.
This study showed that both neuroticism and extraversion had a bidirectional relationship with insomnia. Insomnia had a one - way longitudinal correlation with agreeableness, and conscientiousness had a one - way longitudinal correlation with insomnia. The longitudinal correlation between openness and insomnia was not supported in this study.
虽然人格特质与失眠之间的关联已得到证实，但它们之间的纵向关系仍不明确。
这是一项在中国山东省农村社区居民（n = 482）中进行的为期4年的纵向队列研究。
本研究发现，基线时的神经质（β = 0.175，P < 0.001）、外向性（β = -0.146，P < 0.001）和尽责性（β = -0.168，P < 0.001）与随访时的失眠存在统计学上的显著纵向关联。此外，基线时的失眠与随访时的神经质（β = 0.142，P < 0.01）、外向性（β = -0.209，P < 0.001）和宜人性（β = -0.122，P < 0.01）存在统计学上的显著纵向相关性。
本研究表明，神经质和外向性与失眠均存在双向关系。失眠与宜人性存在单向纵向相关性，尽责性与失眠存在单向纵向相关性。本研究不支持开放性与失眠之间的纵向相关性。
