OBJECTIVE
The present study examined the longitudinal association between personality traits and sleep quality in 4 samples of middle-aged and older adults.
METHOD
Participants (N > 22,000) were adults aged 30 to 107 years old from the Wisconsin Longitudinal Study (WLS), the Midlife in the United States Study (MIDUS), the Health and Retirement Study (HRS), and the Midlife in Japan Study (MIDJA). Personality and sleep quality were assessed at baseline and again 4 to 10 years later.
RESULTS
Scoring lower on neuroticism and higher on extraversion was associated with better sleep quality at baseline and over time, with effect sizes larger than those of demographic factors. Low conscientiousness was associated with a worsening of sleep quality over time. Openness and agreeableness were unrelated to sleep quality. Poor sleep quality at baseline was associated with steeper declines in extraversion, agreeableness, and conscientiousness and a smaller decrease in neuroticism over time.
CONCLUSION
Replicable findings across samples support longitudinal associations between personality and sleep quality. This study identified specific personality traits that are associated with poor and worsening sleep quality, and substantiated previous findings that poor sleep quality is associated with detrimental personality trajectories.

目的
本研究在 4 个中年和老年成年人样本中检验了人格特质与睡眠质量之间的纵向关联。
方法
参与者（N>22000）来自威斯康星纵向研究（WLS）、美国中年研究（MIDUS）、健康与退休研究（HRS）和日本中年研究（MIDJA），年龄在 30 至 107 岁之间。人格和睡眠质量在基线时进行评估，然后在 4 至 10 年后再次评估。
结果
神经质得分较低，外向性得分较高，与基线和随时间推移的睡眠质量较好相关，其效应大小大于人口统计学因素。尽责性较低与随时间推移睡眠质量恶化有关。开放性和宜人性与睡眠质量无关。基线时睡眠质量差与外向性、宜人性和尽责性随时间的急剧下降以及神经质的下降幅度较小有关。
结论
样本间可复制的发现支持人格与睡眠质量之间的纵向关联。本研究确定了与较差和恶化的睡眠质量相关的特定人格特质，并证实了先前的发现，即较差的睡眠质量与不利的人格轨迹有关。
