“…36 Neuroticism is associated with greater likelihood of psychiatric comorbidities (e.g., depression, anxiety), 37 and there is evidence for shared genetic contributions between neuroticism and anxiety disorders. 38 Further, several studies indicate that higher neuroticism significantly predicted poor sleep in non-veteran populations, 39,40 which supports our results.…”

Study Objectives: Sleep disturbances are well documented in relation to trauma exposure and posttraumatic stress disorder (PTSD), but correlates of such disturbances remain understudied in veteran populations. We conducted a preliminary study of sleep disturbances in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans (n = 133; mean [standard deviation] age = 29.8 [4.7] y). Methods: Veterans were assigned to one of three groups based on responses to the Clinician Administered PTSD Scale: control (no trauma-exposure [TE] or PTSD), TE, and PTSD. Sleep disturbance was assessed using the Pittsburgh Sleep Quality Index (PSQI). Measures of resilience, trauma load, personality, coping, alcohol use, and mild traumatic brain injury were also assessed via self-report. Results: The PTSD group had significantly more disturbed sleep (PSQI global score mean = 8.94, standard deviation = 3.12) than control (mean = 5.27, standard deviation = 3.23) and TE (mean = 5.34, standard deviation = 3.17) groups, but there were no differences between TE and control. The same pattern emerged across most PSQI subscales. Results of linear regression analyses indicated that current smoking, Army (versus other military branches), neuroticism, and using substances to cope were all significant correlates of higher sleep disturbance, whereas post-deployment social support was associated with less sleep disturbance. However, when combined together into a model with PTSD status, only neuroticism and substance use coping remained significant as predictors of more disturbed sleep. Conclusions: These initial findings suggest that TE itself may not be an independent risk factor for disturbed sleep in veterans, and that neurotic personality and a tendency to cope by using substances may partially explain sleep disturbance, above and beyond a diagnosis of PTSD.

“…Extraversion, conscientiousness, and emotional stability were found to be positively related to sleep quality (Hintsanen et al, 2014;Huang et al, 2016;Kim et al, 2015;Önder et al, 2014). Stress may be a predisposing factor for poor sleep quality; high levels of extraversion and emotional stability may reduce stress sensitivity (leading an individual to experience less stress) and thus improve sleep (Huang et al, 2016).…”

“…Greater emotional stability was associated with better sleep efficiency in a cohort study conducted with an Australian population (Hintsanen et al, 2014). The results of a cohort study with a Finnish population indicated that greater agreeableness is related to greater sleep duration, and that individuals with higher levels of extraversion, agreeableness, and emotional stability show better sleep efficiency (Hintsanen et al, 2014). These associations may be based on the characteristics of individuals who score high or low for certain traits.…”

The Mediating Role of Sleep Quality in the Relationship Between Personality and Subjective Well-Being

The literature has shown that personality is linked with subjective well-being. However, the nature of this link and its underlying mechanisms require further investigation. This study examined the potential associations between personality traits and facets of subjective well-being, when the effects of the demographic variables were taken into account. This study also tested the mediating role of sleep quality in these associations. In late 2013, a national probability sample of Australian residents (N = 13,424; M age = 44.3 years; 47% male) completed a questionnaire comprising measures of personality, subjective well-being, sleep quality, and demographic variables. Structural equation modeling showed that when controlling for the demographic variables, each personality trait was uniquely related to facets of subjective well-being. The results also demonstrated that sleep quality partially mediated these associations. Individuals showing higher levels of extraversion, conscientiousness, and emotional stability reported better sleep quality and greater subjective well-being, whereas individuals displaying greater agreeableness reported worse sleep quality and poorer subjective well-being. These results differentiated the personality traits in terms of their connections with the facets of subjective well-being and highlighted the potential role of good sleep quality in promoting subjective well-being.

“…Additionally, sleep disorders have negative effects on people's mood (15). This is while about 20% of the adult population is affected by sleep problems (16). People, who experience sleep disorders, not only suffer from fatigue, but also from defects in cellular repair, defects in learning memory, increase in anxiety and decrease in quality of life.…”

Background: During pregnancy, due to special hormonal and physiological changes that occur in the body, sleep disorders are very prevalent; therefore, positive psychological states and emotions can have major impacts on overall sleep quality among pregnant women. Objectives: The aim of this study was to examine the effect of 15 positive psychological states (trust in God, optimism, a sense of efficacy, accepting responsibilities, a sense of control, purposefulness, hope, meaningfulness in life, life satisfaction, positive mood and happiness, being social, self-esteem and self-worth, a sense of peace, appreciation, and forgiveness) on predicting sleep quality among pregnant women. Materials and Methods: This descriptive study followed a correlational-predictive design. The statistical population of this study included all pregnant women referred to health care centers in Khash in the first half of 2015, which included 890 individuals. The sampling method was multistage cluster sampling. Overall, 268 questionnaires were distributed among pregnant women, who had the inclusion criteria of the current study, in order to be answer freely and voluntarily. Moreover, to collect data, two questionnaires including positive psychological states (PPS) and the Pittsburgh sleep quality index (PSQI) were used. Results:The results of the correlation coefficient indicated that optimism, purposefulness, hope, meaningfulness in life, life satisfaction, positive mood and happiness, a sense of peace, trust in God and forgiveness were significantly related to high sleep quality

Five-factor personality traits and sleep: Evidence from two population-based cohort studies.

Abstract: Increasing the knowledge on personality and sleep may benefit more personalized treatment of sleep disorders and help in personnel selection to jobs in which it is critical to stay alert. However, longitudinal research is needed to confirm the current findings.
