Biological and psychological correlates of self-reported and objective sleep measures

ObjectiveObjective and self-reported sleep are only moderately correlated and it is uncertain if these two types of sleep measures are associated with distinct biological and psychological outcomes.MethodsParticipants were 119 healthy women aged 26 years on average. Cortisol and blood pressure assessed over one day were the measures of biological function. Psychological variables included optimism, life satisfaction, positive and negative affect as well as emotional distress. Sleep was assessed with the Pittsburgh Quality Index (PSQI), wrist actigraphy and sleep diaries.ResultsGlobal sleep ratings on the PSQI were unrelated to objective sleep efficiency, duration or latency. Sleep duration derived from sleep diaries was highly correlated with objective duration but was unrelated to the PSQI measure. More disturbed sleep on the PSQI was associated with lower psychological wellbeing, as indicated by reduced levels of optimism, life satisfaction and positive affect as well as greater negative affect and emotional distress. Objective sleep efficiency was reduced among participants with lower positive and higher negative affect but there were no other associations between objective sleep indicators and psychological variables tested in our study. Participants with poorer self-reported sleep had lower cortisol awakening response while those with longer objective sleep latency had higher diastolic blood pressure, independently of covariates.ConclusionOur study reveals that self-reported and objective sleep measures, in particular those regarding sleep quality, are weakly associated but have different psychological and biological correlates. This suggests that findings relating self-reported sleep may not necessarily be corroborated by objective sleep indicators.     

Longitudinal study of depression and health status in pregnant women: incidence, course and predictive factors

The aim of this study was to determine the effect of isolated psychological intimate partner violence and psychosocial factors (social support and alcohol or drug use by a partner/family member) on psychological well-being (depression or poor self-perceived health status) at 5 and 12 months post-partum. A longitudinal cohort study was carried out with a consecutive sample of 1,400 women in their first trimester of pregnancy, who attended the prenatal programme in the Valencia Region (Spain) in 2008 and were followed up at 5 months and 12 months post-partum. A logistic regression model was fitted using generalized estimating equations, to assess the effect of isolated psychological intimate partner violence, social support, alcohol consumption and illicit drug use problems by a partner or family member on subsequent psychological well-being at follow-up. We observed a decrease in the incidence of poorer psychological well-being (post-partum depression and poor self-perceived health status) at 12 months post-partum. The strongest predictor of poor psychological well-being was depression (AOR = 6.83, 95 % CI: 3.44–13.58) or poor self-perceived health status (AOR = 5.34, 95 % CI: 2.37–12.02) during pregnancy. Isolated psychological IPV increased the risk of a deterioration in psychological well-being. Having a tangible social network was also a predictor of both post-partum depression and poor self-perceived health status. The effect of functional social support varied according to the type of psychological well-being indicator being used. Problems of alcohol consumption or illicit drug use by a partner or family member were a predictor of post-partum depression only. Psychological well-being during the first year after birth is highly affected by isolated psychological IPV and psychosocial factors.     

Bidirectional,Temporal Associations of Sleep with Positive Events,Affect, and Stressors in Daily Life Across a Week

Background

Sleep is intricately tied to emotional well-being, yet little is known about the reciprocal links between sleep and psychosocial experiences in the context of daily life.

Purpose

The aim of this study is to evaluate daily psychosocial experiences (positive and negative affect, positive events, and stressors) as predictors of same-night sleep quality and duration, in addition to the reversed associations of nightly sleep predicting next-day experiences.

Methods

Daily experiences and self-reported sleep were assessed via telephone interviews for eight consecutive evenings in two replicate samples of US employees (131 higher-income professionals and 181 lower-income hourly workers). Multilevel models evaluated within-person associations of daily experiences with sleep quality and duration. Analyses controlled for demographics, insomnia symptoms, the previous day’s experiences and sleep measures, and additional day-level covariates.

Results

Daily positive experiences were associated with improved as well as disrupted subsequent sleep. Specifically, positive events at home predicted better sleep quality in both samples, whereas greater positive affect was associated with shorter sleep duration among the higher-income professionals. Negative affect and stressors were unrelated to subsequent sleep. Results for the reversed direction revealed that better sleep quality (and, to a lesser degree, longer sleep duration) predicted emotional well-being and lower odds of encountering stressors on the following day.

Conclusions

Given the reciprocal relationships between sleep and daily experiences, efforts to improve well-being in daily life should reflect the importance of sleep.

     

Relationship between hostility and subjective sleep quality

While hostility and sleep disturbance are the potential risk factors for health problems and disease, few studies have examined the relationship between the two factors. The present study was performed to investigate the relationship between hostility and sleep problems assessed both subjectively and objectively in a nonclinical sample. Sixty-one healthy subjects were enrolled in this study. Hostility was measured according to the Cook–Medley hostility scale. Subjective sleep quality was evaluated according to the global score of the Pittsburgh Sleep Quality Index. Objective sleep was evaluated using actigraphy. A multiple regression analysis revealed that a higher level of hostility was significantly associated with the global score of the Pittsburgh Sleep Quality Index and that a higher level of depression was not associated with the global score of the Pittsburgh Sleep Quality Index. Objective sleep measures were not found to be associated with hostility. Confirming the robust relationship between poor sleep and hostility would have several important treatment implications for preventing health problems.     

Epidemiology of chronic pain with psychological comorbidity: prevalence, risk, course, and prognosis.

OBJECTIVE: To review the relation between chronic pain and psychological comorbidities, and the influence on course and prognosis, based on epidemiologic and population studies. METHOD: We present a narrative overview of studies dealing with the epidemiology of chronic pain associated with mental health and psychiatric factors. Studies were selected that were of good quality, preferably large studies, and those that dealt with prevalences, course and prognosis of chronic pain, risk factors predicting new pain and comorbid disorders, and factors that affect health outcomes. RESULTS: Chronic pain is a prevalent condition, and psychological comorbidity is a frequent complication that significantly changes the prognosis and course of chronic pain. In follow-up studies, chronic pain significantly predicts onset of new depressions, and depression significantly predicts onset of new chronic pain and other medical complaints. Age, sex, severity of pain, psychosocial problems, unemployment, and compensation are mediating factors in course and prognosis. CONCLUSION: In assessment of chronic pain, the evidence from epidemiologic studies makes it clear that chronic pain can best be understood in the context of psychosocial factors.     

Consumer-run service participation, recovery of social functioning, and the mediating role of psychological factors

OBJECTIVE: This study examined the relationship between participation in consumer-run services and recovery of social functioning among persons diagnosed as having serious mental illness. It also assessed the role of psychological factors in mediating this relationship. METHODS: Research questions investigated were whether involvement in consumer-run services is positively associated with recovery when premorbid and demographic factors are controlled for, whether psychological factors are positively associated with recovery irrespective of involvement in consumer-run services, and whether the relationship between involvement in consumer-run services and recovery is mediated by the psychological factors. The factors examined were self-efficacy, hopefulness, and active coping strategies. Sixty participants with a past or present diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder and at least one past psychiatric hospitalization were recruited from a community mental health center and two consumer-run programs. Data were collected on hopefulness, self-efficacy, coping strategies, social functioning, and premorbid and demographic characteristics. RESULTS: Findings indicated that participants involved in consumer-run services had better social functioning than those involved only in traditional mental health services, that psychological variables were significantly associated with social functioning, and that the relationship between involvement in consumer-run services and social functioning was partly mediated by the use of more problem-centered coping strategies. Premorbid and demographic factors did not account for the relationship between psychosocial variables and social functioning, although education was a significant predictor of social functioning. CONCLUSIONS: The findings support the view that psychosocial factors may play a role in facilitating good community adjustment for individuals diagnosed as having serious mental illness.     

Sleep quality in times of Covid-19 pandemic

BackgroundDue to the 2019 novel coronavirus (COVID-19) disease outbreak, social distancing measures were imposed to control the spread of the pandemic. However, isolation may affect negatively the psychological well-being and impair sleep quality. Our aim was to evaluate the sleep quality of respiratory patients during the COVID-19 pandemic lockdown.MethodsAll patients who underwent a telemedicine appointment from March 30 to April 30 of 2020 were asked to participate in the survey. Sleep difficulties were measured using Jenkins Sleep Scale.ResultsThe study population consisted of 365 patients (mean age 63.9 years, 55.6% male, 50.1% with sleep-disordered breathing [SDB]). During the lockdown, 78.9% of participants were confined at home without working. Most patients (69.6%) reported at least one sleep difficulty and frequent awakenings was the most prevalent problem. Reporting at least one sleep difficulty was associated with home confinement without working, female gender and diagnosed or suspected SDB, after adjustment for cohabitation status and use of anxiolytics. Home confinement without working was associated with difficulties falling asleep and waking up too early in the morning. Older age was a protective factor for difficulties falling asleep, waking up too early and non-restorative sleep. Notably, SDB patients with good compliance to positive airway pressure therapy were less likely to report sleep difficulties.ConclusionsHome confinement without working, female gender and SDB may predict a higher risk of reporting sleep difficulties. Medical support during major disasters should be strengthened and potentially delivered through telemedicine, as this comprehensive approach could reduce psychological distress and improve sleep quality.     

Predictors of psychological distress and well-being in women with chronic musculoskeletal pain: two sides of the same coin?

OBJECTIVE: To date, few results on well-being in chronic-pain patients have been published, while several studies in patients without pain have indicated that well-being may not be equivalent to absence of psychological distress. The aim of the present study was to investigate the relationship between psychological distress and well-being and to identify the predictors of each in patients with chronic nonmalignant pain. METHODS: Sixty-nine women with chronic multiregional musculoskeletal pain, 41 of whom met American College of Rheumatology criteria for fibromyalgia, completed questionnaires on pain, fatigue, stiffness, physical disability (Fibromyalgia Impact Questionnaire), psychological distress [Multidimensional Affect and Pain Survey (MAPS), Symptom Check List-90 (SCL-90), State-Trait Anxiety Inventory Form Y2 (STAI-Y2)], and hedonic and eudaimonic well-being (MAPS). RESULTS: Patients reported increased amounts of psychological distress (STAI-Y2 and SCL-90) compared to healthy people. Multiple regression analysis of patient data demonstrated that higher psychological distress was related to higher age, more intense pain, a higher positive tender point count, and more physical disability. Well-being (both hedonic and eudaimonic aspects) decreased with higher disability, but was independent of age, pain intensity, and number of positive tender points. Bivariate correlations showed that psychological distress was moderately related to eudaimonic well-being and strongly related to positive affect, an aspect of hedonic well-being. CONCLUSION: In patients with chronic musculoskeletal pain, self-reports of well-being and low psychological distress only partially overlap with each other and are differently related to major patient symptoms, supporting the relevance of the concept of well-being to chronic-pain research and a need for further studies in this field.     

Social Support and Well-being at Mid-Life Among Mothers of Adolescents and Adults with Autism Spectrum Disorders

The present study investigated the impact of social support on the psychological well-being of mothers of adolescents and adults with ASD (n?=?269). Quantity of support (number of social network members) as well as valence of support (positive support and negative support) were assessed using a modified version of the "convoy model" developed by Antonucci and Akiyama (1987). Having a larger social network was associated with improvements in maternal well-being over an 18-month period. Higher levels of negative support as well as increases in negative support over the study period were associated with increases in depressive symptoms and negative affect and decreases in positive affect. Social support predicted changes in well-being above and beyond the impact of child behavior problems. Implications for clinical practice are discussed.     

Poor sleep increases the prospective risk for recurrent events in middle-aged women with coronary disease. The Stockholm Female Coronary Risk Study

OBJECTIVE: We investigated the prognostic impact of sleep complaints in women with CHD and also examined whether the association between sleep problems and cardiac events could be explained by depression. METHODS: All women patients, aged 65 or under who were admitted with an acute coronary syndrome between 1991 and 1994 in Stockholm, were followed for 5 years for recurrent coronary events. Sleep complaints and depression were measured at baseline using standardized questionnaires. Quality of sleep, restorative function of sleep, and snoring were assessed by the Karolinska Sleep Questionnaire (KSQ), and depressive symptoms by a questionnaire developed by Pearlin. RESULTS: Poor sleep quality was associated with recurrent cardiac events. After multivariate adjustment for age, and standard risk factors, the hazard ratio (HR) for women with poor as compared with good sleep quality was 2.5 (95% CI: 1.2-5.2). Controlling for depression did not change this result substantial. Not waking up well-rested yielded a similarly increased risk (HR = 2.4; 95% CI: 1.2-4.6). Women with both poor sleep quality and depression had a worse prognosis than women free from these complaints (HR = 2.6; 95% CI: 1.0-6.4). Heavy snoring was not related to prognosis. CONCLUSIONS: Our results indicate that poor sleep and sleep without a restorative function are associated with poor prognosis in female coronary patients. This association is not explained by depressive symptoms or by standard coronary risk factors.     

Night-shift work,sleep duration,daytime napping,and breast cancer risk

ObjectivesSleep habits vary among different countries, and sleep problems may cause various health problems. The aim of our study was to evaluate the separate and combined associations of night-shift work, sleep duration, and daytime napping with breast cancer risk among the Chinese population.MethodsThis study conducted face-to-face interviews with 712 women diagnosed with incident invasive breast cancer before treatment and 742 age-matched controls. Information on sleep habits, demographic characteristics, and suspected or established risk factors of breast cancer were collected from the two groups. Multivariate logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs).ResultsNight-shift work was associated with an increased risk of breast cancer [OR (95% CI): 1.34 (1.05–1.72)]. Compared to women with a sleep duration of 6.1–8.9 h/day, women who had shorter [(≤6.0 h/day) (OR (95% CI): 1.53 (1.10–2.12)] and longer (≥9.0 h/day) sleep duration [(OR (95% CI): 1.59 (1.17–2.17)] had an increased risk of breast cancer. In addition, daytime napping was associated with a reduced risk of breast cancer among night-shift workers [OR (95% CI): 0.57 (0.36–0.90)], but no association was found among women who never had night-shift work [OR (95% CI): 1.01 (0.75–1.35)] (P for interaction = 0.054). Night-shift work and longer sleep duration also synergistically increased breast cancer risk [OR (95% CI): 3.69 (1.94–7.02)] (P for interaction = 0.009).ConclusionsSleep problems, including night-shift work, and shorter and longer sleep duration, are associated with an increased breast cancer risk. In particular, the combined effects of night-shift work with no daytime napping or longer sleep duration are greater than the independent effects.     

Lighten UP! A community-based group intervention to promote psychological well-being in older adults

Objectives: Aging is often characterized by declines in physical and mental health and increased risk for depression and social isolation. A protective factor that has been found to effectively moderate these phenomena is psychological well-being. The aim of his study was to pilot test a novel group intervention (Lighten UP! program) for the promotion of psychological well-being in older adults living in the community.

Methods: Lighten UP! is an eight-week program consisting of 90-minute group session designed to teach participants to identify and savor positive experiences across multiple domains of eudaimonic well-being. It was delivered to a sample of 103 men and women aged 60 or over, that were assessed pre- and post-intervention with Ryff's Psychological Well-being Scale (PWB), Life Satisfaction scale, Geriatric Depression Scale, Symptom Questionnaire, and items measuring sleep complaints and social well-being.

Results: At the end of the eight weeks, participants reported significantly increased PWB, life satisfaction, and social well-being along with lower levels of depression and fewer physical symptoms and sleep complaints. These gains were particularly robust for individuals with lower pre-program levels of PWB.

Conclusions: This pilot investigation suggests the feasibility of a short group program for enhancing well-being in older adults. Future controlled investigations with long-term follow-up assessment are needed to confirm the effectiveness and sustained benefits of the Lighten UP! program.

Sleep and well-being in young men with neuromuscular disorders receiving non-invasive ventilation and their carers

Nocturnal ventilation has improved the physical status and life span of childhood neuromuscular disorders: the purpose of this study was to assess the implications for sleep and well-being in patients and carers. Ten young men (age range 12–25 years) with neuromuscular disorders on assisted ventilation and/or their main carers completed questionnaires on sleep quality, physical and psychological well-being, family burden and function. Both patients and parents expressed satisfaction with ventilation treatment. Compared to standardised values patients reported reduced sleep quality, but their mental health was not substantially affected. Poor sleep quality in carers – but not in patients – was significantly associated with risk for emotional (anxiety and depressive) disorders, reduced physical/emotional health, family burden and difficulty. We conclude that patients were generally well adapted psychologically, but sleep quality was poor and in carers this was linked to reduced well-being and family burden.     

Psychosocial correlates of aspects of sleep quality in community-dwelling Irish older adults

Objectives: While it is known that psychosocial factors affect overall sleep quality, there is little consensus on the factors that affect different aspects of sleep. The Pittsburgh Sleep Quality Index (PSQI) provides a means of examining these separate aspects of sleep.

Method: This study investigated whether the different components of the PSQI are affected by different psychosocial factors, or whether all aspects of sleep are associated with the same factors. 505 community-dwelling older adults took part in this study. Psychosocial status, comprising of measures of depression, anxiety, perceived stress, social and emotional loneliness and personality, was assessed for each participant. Health-related factors (pain, comorbidities, polypharmacy) as well as age and gender were also measured.

Results: Neuroticism, depression, anxiety and age accounted for overall sleep quality. Further analyses revealed that different psychosocial and health-related factors such as pain, loneliness and personality accounted for scores in the different components.

Conclusion: Interventions for poor sleep quality may depend on the aspect of sleep affected in the individual, and treatment may be contingent on a number of different psychosocial variables. Future research could focus on developing personalised treatment programs for older adults with sleep complaints.     

La somnolence chez les adolescents: étiologie et conséquences multiples

Over the past century a dramatic decline in sleep duration among adolescents, such as more than one hour of sleep loss per night, has been reported. A debt in sleep duration could lead to sleep deprivation, a major risk factor associated with daytime sleepiness. Sleepiness refers to the inability to maintain an adequate level of alertness during the day which may result in more or less being able to control falling asleep at inappropriate times. This literature review updates on sleepiness regarding its characteristics, etiology and consequences on adolescents. Studies revealed that from 25 % to 78 % of adolescents had reported sleepiness. Its manifestations may include heavy lids, yawns, difficulties to concentrate and emotional irritability. In addition, while it is recommended that adolescents under 18 years-old should sleep from eight to ten hours a night, only 63 % of them actually do so. The etiology of sleep deprivation and sleepiness in this population can be explained by various biological and societal factors. First, the sleep-wake cycle of adolescents shows a biological shift from the beginning of pubertal maturation, described as a perfect storm. It refers to a social jetlag by going to sleep and waking up later and accumulating a sleep debt during weekdays which they try to reimburse during weekends. This phenomenon can be explained by physiological changes such as a slower accumulation of sleep pressure. In addition to this perfect storm, environmental and societal factors contribute to the social jetlag and reduce sleep duration in adolescents. Screen exposure before bedtime can delay sleep and wake onset, which is a risk factor for sleeping debt. Substance use such as caffeine, cigarettes or electronic vaporizer, ADHD or freely available medication, alcohol, cannabis use or drug consumption could further disrupt sleep-wake cycle by stimulating, depressing or otherwise disrupting the central nervous system. Early, before 8:30 am, class start times have been associated with chronic sleep deprivation, higher level of sleepiness and delayed melatonin peak secretion. Adolescents working or doing extracurricular occupations for more than 20 hours a week are more at risk for reduced sleep duration and sleepiness. Parental supervision about sleep during the weekdays were associated with more appropriate bedtime. Adolescents from low socio-demographic characteristics and from minority ethnic groups have reported displaying a shorter sleep duration. Finally, sleep disorders of a physiological origin such as narcolepsy, sleep apnea or restless legs syndrome, may explain the sleep deprivation and sleepiness. Sleep deprivation and sleepiness in adolescents have consequences on their health. Cognitive functioning, such as problem solving, attention or memory, as well as school performance, can be compromised by sleep deprivation and sleepiness. At the psychological level, adolescents reporting sleepiness are more prone to display mental health problems: associations were found between sleepiness and subjective perception of depression, anxiety, somatic complaints as well as with antisocial behaviors. Finally, 68 % of 16 year-old adolescents reported they drove a car, and the reported sleepiness could lead to road accidents due to reduced attentional functioning, reaction time and decision-making abilities. In the United-States, from 7 % to 16.5 % of deadly accidents were related to driving while drowsy. Highlighting etiology and problems associated with sleep deprivation and sleepiness in adolescents could guide researchers and clinicians towards the development of possible interventions. Public health measures and knowledge transfer programs regarding modifiable psychosocial and societal factors associated with sleep-wake bioregulation could increase awareness in parents as well as in political and societal decision makers.     

Clarification of the factor structure of the 12-item General Health Questionnaire among Japanese adolescents and associated sleep status

If the factors affecting the mental health status of adolescents and their association with sleep status could be clarified, this information would be helpful for formulating lifestyle and healthcare guidance for the promotion of healthy growth and the prevention of mental problems in these individuals. The purpose of this study was to clarify (1) the factor structure of the 12-item General Health Questionnaire (GHQ-12), and (2) the associations between the factors extracted from this questionnaire and lifestyle, in particular sleep status, by using a representative sample population of Japanese adolescents. One hundred three thousand sixty hundred fifty self-administered questionnaires were collected from students enrolled in junior high and high schools in Japan. Of these questionnaires, 99,668 were analyzed. Sleep duration, subjective sleep assessment, bedtime, and insomnia symptoms of these students over the past month were studied to investigate sleep status. The factor analyses yielded two factors: depression/anxiety and loss of positive emotion. Sleep duration of less than 7 h was found to be associated with both depression/anxiety and loss of positive emotion, whereas sleep duration of 8 h or more was associated only with loss of positive emotion. Subjective sleep assessment and insomnia symptoms were associated with both depression/anxiety and loss of positive emotion. It was demonstrated that two underlying factors of mental health status were associated with differences in sleep status. In order to improve the mental health status of adolescents, it is important to provide guidance about sleep and lifestyle habits according to the mental health status of the individual.     

Daytime sleeping, sleep disturbance, and circadian rhythms in the nursing home.

OBJECTIVE: This study reports the frequency of abnormal daytime sleeping and identifies factors related to daytime sleeping, nighttime sleep disturbance, and circadian rhythm abnormalities among nursing home residents. METHODS: The authors conducted secondary analysis of data collected under usual care conditions within a nonpharmacologic sleep intervention trial. All residents from four Los Angeles nursing homes were screened for daytime sleeping (asleep>or=15% of observations, 9:00 am-5:00 pm). Consenting residents with daytime sleeping had two nights of wrist actigraphy to assess nighttime sleep disturbance (asleep<80%, 10:00 pm-6:00 am). Residents with nighttime sleep disturbance completed an additional 72-hour wrist actigraphy recording to assess circadian activity rhythms and light exposure. RESULTS: Sixty-nine percent of 492 observed residents had daytime sleeping, of whom 60% also had disturbed nighttime sleep. Sleep disturbance and daytime sleeping were rarely documented in medical records. Residents spent one-third of the day in their rooms, typically in bed, and were seldom outdoors or exposed to bright light. More time in bed and less social activity were significant predictors of daytime sleepiness. Ninety-seven percent of residents assessed had abnormal circadian rhythms. More daytime sleeping and less nighttime sleep were associated with weaker circadian activity rhythms. Later circadian rhythm acrophase (peak) was associated with more bright light exposure. CONCLUSION: Daytime sleepiness, nighttime sleep disturbance, and abnormal circadian rhythms were common in nursing home residents. Modifiable factors (e.g., time in bed) are associated with sleep/wake abnormalities. Mental health specialists should consider the complexity of factors causing sleep problems in nursing home residents.     

Job-related factors associated with changes in sleep quality among healthcare workers screening for 2019 novel coronavirus infection: a longitudinal study

BackgroundSleep disorders may exacerbate many physical and mental health conditions, causing difficulty function in a healthcare setting. Workers screening for the 2019 novel coronavirus (2019-nCoV) infection have a high risk of not only occupational exposure to the virus but also sleep disorders. However, the job-related factors associated with reduced sleep quality remain unclear.MethodsAll healthcare workers temporarily scheduled to screen the 2019-nCoV patients were asked to complete a self-administered questionnaire that included questions on demographics, job-related factors, and sleep quality as assessed using the Pittsburgh Sleep Quality Index (PSQI). Sleep quality was assessed over a one-month follow-up period.ResultsA total of 116 doctors and 99 nurses were recruited for this study. The total scheduled work time was 14.78 ± 6.69 days during follow-up. Some job-related factors, such as number of work days, years of work experience, and subjective psychological stress, were associated with changes in the PSQI score. During the study, some workers tried out cognitive behavioral therapy (CBT) for sleep disorders using methods that were available online and easily accessible. Adopting online CBT was shown to be associated with scores of components of sleep quality, sleep latency, and sleep disturbance (β = −0.152, P = 0.01; β = −0.175, P = 0.008; and β = −0.158, P = 0.011, respectively).ConclusionsHealthcare workers involved in screening for 2019-nCoV experienced reduced sleep quality, and a reasonable work schedule may help with maintaining sleep quality. In addition, interventions for healthcare workers should target self-help sleep assistance.
