Dispositional characteristics like emotional stability and social cynicism have been consistently associated with negative affect, which is a known predictor and outcome of poor sleep quality. This study hypothesized a bidirectional relationship of sleep quality with emotional stability and social cynicism over a five-year period.
Participants were 7,181 Chinese people, who completed two waves of online surveys from a larger panel study. Questionnaires on Big Five personality traits, social cynicism, and sleep quality were administered twice at a five-year interval.
Cross-lagged analysis revealed a significant bidirectional relationship between emotional stability and sleep quality over five years as hypothesized. However, there was no association between sleep quality and social cynicism in either direction.
Our study provides consistent evidence of a bidirectional relationship between sleep quality and emotional stability in a five-year time-frame among a younger population (mean age = 24.86). Given the critical role of emotional stability in various areas of functioning, the findings highlight the importance of sleep health education in young adults, who are going through a critical period of personality development.
性格特征，如情绪稳定性和社会犬儒主义，与负面情绪密切相关，而负面情绪是睡眠质量差的已知预测因素和结果。本研究假设在五年内，睡眠质量与情绪稳定性和社会犬儒主义之间存在双向关系。
参与者为 7181 名中国人，他们来自一项更大的面板研究的两次在线调查。在五年的时间间隔内，两次进行了关于大五人格特质、社会犬儒主义和睡眠质量的问卷调查。
交叉滞后分析显示，情绪稳定性和睡眠质量在五年内呈假设的双向关系。然而，在任何一个方向上，睡眠质量与社会犬儒主义之间都没有关联。
我们的研究在五年的时间框架内，在年轻人群体（平均年龄为 24.86 岁）中提供了一致的证据，证明了睡眠质量与情绪稳定性之间存在双向关系。鉴于情绪稳定性在各种功能领域中的重要作用，这些发现强调了在年轻人中进行睡眠健康教育的重要性，因为他们正处于人格发展的关键时期。
