Personality and sleep quality: Evidence from four prospective studies.

Abstract

Objective The present study examined the longitudinal association between personality traits and sleep quality in four 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.

Personality Traits Predict Regression of Pelvic Girdle Pain after Pregnancy: A Longitudinal Follow-up Study.

“…A tendency to be emotionally unstable is common in those who are highly neurotic [41]. Studies have indicated that mothers with low scores in emotional stability are more likely to prefer a cesarean delivery and have complications during delivery, including failure to progress, foetal distress, and severe tearing [41,43]. The present results further nd that high neuroticism relates to persistent PGP.…”

“…Strong evidence has been found that conscientiousness, extraversion, and neuroticism have connections with some behaviors that make the risk of experiencing pain arise [39,42,43]. For instance, patients high in conscientiousness, responsible, self-disciplined, and inclined to adhere to social norms, consume less alcohol and fewer cigarettes than average [42,43]. Higher neuroticism and lower extraversion tend to have physical inactivity [42], poor sleep patterns [43], and tobacco use [44].…”

Health outcomes associated with participating in community care centres for older people in Taiwan

“…Since the older participants in the CCCs expect more socialisation or the happiness associated with learning things rather than following strict rules or achieving great performance, a task‐oriented management style may bring greater pressure and burden older adults, resulting in worse mental health outcomes (Pyc, Meltzer, & Liu, ). It is also possible that older participants who were more anxious and had poor sleep quality were also more attracted to a task‐oriented management style CCC, and it is their personality, rather than the type of CCC, that is more related to poor health outcomes (Stephan, Sutin, Bayard, Križan, & Terracciano, ).…”

Polygenic score for neuroticism is related to sleep difficulties

“…Among these factors, personality traits, an individual's characteristic ways of feeling, thinking and behaving, have been found to contribute to sleep‐related outcomes . Of the traits defined by the Five Factor Model of Personality, cross‐sectional and longitudinal studies suggest that higher neuroticism, the tendency to experience negative emotions and distress, is the trait most consistently and strongly related to lower sleep quality and worsening sleep over time . This association is found across different cultures and measures, including subjective and objective assessments of sleep …”
