Ten-Year Stability of an Insomnia Sleeper Phenotype and Its Association With Chronic Conditions.

OBJECTIVE: To identify distinct sleep health phenotypes in adults, examine transitions in sleep health phenotypes over time, and subsequently relate these to the risk of chronic conditions. METHODS: A national sample of adults from the Midlife in the United States study ( N = 3683) provided longitudinal data with two time points (T1: 2004-2006, T2: 2013-2017). Participants self-reported on sleep health (regularity, satisfaction, alertness, efficiency, duration) and the number and type of chronic conditions. Covariates included age, sex, race, education, education, partnered status, number of children, work status, smoking, alcohol, and physical activity. RESULTS: Latent transition analysis identified four sleep health phenotypes across both time points: good sleepers, insomnia sleepers, weekend catch-up sleepers, and nappers. Between T1 and T2, the majority (77%) maintained their phenotype, with the nappers and insomnia sleepers being the most stable. In fully adjusted models with good sleepers at both time points as the reference, being an insomnia sleeper at either time point was related to having an increased number of total chronic conditions by 28%-81% at T2, adjusting for T1 conditions. Insomnia sleepers at both time points were at 72%-188% higher risk for cardiovascular disease, diabetes, depression, and frailty. Being a napper at any time point related to increased risks for diabetes, cancer, and frailty. Being a weekend catch-up sleeper was not associated with chronic conditions. Those with lower education and unemployed were more likely to be insomnia sleepers; older adults and retirees were more likely to be nappers. CONCLUSION: Findings indicate a heightened risk of chronic conditions involved in suboptimal sleep health phenotypes, mainly insomnia sleepers.

Association of back pain with all-cause and cause-specific mortality among older men: a cohort study.

OBJECTIVE: We evaluated whether more severe back pain phenotypes-persistent, frequent or disabling back pain-are associated with higher mortality among older men. METHODS: In this secondary analysis of a prospective cohort, the Osteoporotic Fractures in Men (MrOS) study, we evaluated mortality rates by back pain phenotype among 5215 older community-dwelling men (mean age, 73 years, SD = 5.6) from six U.S. sites. The primary back pain measure used baseline and year five back pain questionnaire data to characterize participants as having: no back pain; non-persistent back pain; infrequent persistent back pain; or frequent persistent back pain. Secondary measures of back pain from year five questionnaire included disabling back pain phenotypes. The main outcomes measured were all-cause and cause-specific mortality. RESULTS: After the year five exam, during up to 18 years of follow-up (mean follow-up=10.3 years), there were 3513 deaths (1218 cardiovascular, 764 cancer, 1531 other). A higher proportion of men with frequent persistent back pain versus no back pain died (78% versus 69%; sociodemographic-adjusted HR = 1.27, 95%CI=1.11-1.45). No association was evident after further adjusting for health-related factors such as self-reported general health and comorbid chronic health conditions (fully-adjusted HR = 1.00; 95%CI=0.86-1.15). Results were similar for cardiovascular mortality and other mortality, but we observed no association of back pain with cancer mortality. Secondary back pain measures including back-related disability were associated with increased mortality risk that remained statistically significant in fully-adjusted models. CONCLUSION: While frequent persistent back pain was not independently associated with mortality in older men, additional secondary disabling back pain phenotypes were independently associated with increased mortality. Future investigations should evaluate whether improvements in disabling back pain effect general health and well-being or mortality.

Too little or too much: nonlinear relationship between sleep duration and daily affective well-being in depressed adults.

BACKGROUND: In addition to having higher negative affect and lower positive affect overall, depressed individuals exhibit heightened affective reactivity to external stimuli than non-depressed individuals. Sleep may contribute to day-to-day fluctuations in depressed individuals, given that sleep disturbance is a common symptom of depression. Yet, little is known about changes in daily affect as a function of nightly sleep duration in depressed adults and non-depressed adults. The current study examined whether and how naturally-occurring sleep duration is associated with negative and positive affect, and how these associations differ between depressed vs. non-depressed adults. METHODS: Data were drawn from the second wave of the National Study of Daily Experiences (NSDE), a daily diary project of the Midlife in the United States (MIDUS) study. The sample of 2,012 adults (Mage=56.5; 57% female; 84% white) completed eight-day diary interviews via telephone on their daily experiences including nightly sleep duration and negative and positive affect. They also completed assessments of the Composite International Diagnostic Interview-Short form, and depressed status was determined based on DSM-III. Multilevel regression models with linear, quadratic, and cubic terms of sleep duration examined the nonlinear relationship between nightly sleep duration and daily affect. Interaction terms with depression status were added to examine differences between depressed and non-depressed adults. RESULTS: Depressed adults exhibited significant and greater fluctuations in daily affect as a function of nightly sleep duration than non-depressed adults. Specifically, the degree of decrease in positive affect and increase in negative affect was greater when depressed adults slept 2 or more hours less or longer than their usual sleep hours. Non-depressed adults exhibited relatively stable daily affect regardless of their nightly sleep hours. CONCLUSIONS: Sleep duration is nonlinearly associated with affect in daily lives of depressed adults, highlighting that both having too little sleep and excessive sleep are associated with adverse daily affective well-being. Implementing sleep interventions to promote an appropriate sleep duration may help improve daily affect among depressed adults.

Employee Cardiometabolic Risk Following a Cluster-Randomized Workplace Intervention From the Work, Family and Health Network, 2009-2013.

Objectives. To examine whether workplace interventions to increase workplace flexibility and supervisor support and decrease work-family conflict can reduce cardiometabolic risk. Methods. We randomly assigned employees from information technology (n = 555) and long-term care (n = 973) industries in the United States to the Work, Family and Health Network intervention or usual practice (we collected the data 2009-2013). We calculated a validated cardiometabolic risk score (CRS) based on resting blood pressure, HbA1c (glycated hemoglobin), HDL (high-density lipoprotein) and total cholesterol, height and weight (body mass index), and tobacco consumption. We compared changes in baseline CRS to 12-month follow-up. Results. There was no significant main effect on CRS associated with the intervention in either industry. However, significant interaction effects revealed that the intervention improved CRS at the 12-month follow-up among intervention participants in both industries with a higher baseline CRS. Age also moderated intervention effects: older employees had significantly larger reductions in CRS at 12 months than did younger employees. Conclusions. The intervention benefited employee health by reducing CRS equivalent to 5 to 10 years of age-related changes for those with a higher baseline CRS and for older employees. Trial Registration. ClinicalTrials.gov Identifier: NCT02050204. (Am J Public Health. 2023;113(12):1322-1331. https://doi.org/10.2105/AJPH.2023.307413).

Sleep quality moderates the association between family bereavement and heart rate variability.

Two separate bodies of literature point to the link between family bereavement and cardiovascular health and between sleep quality and cardiovascular outcomes. However, less is known about the joint influence of family bereavement and sleep quality on cardiovascular functioning. The aims of this study were to examine the relationships between experiencing the death of a family member and heart rate variability (HRV) and to further explore whether these associations differ by sleep quality. Using data from the Midlife in the United States (MIDUS) Biomarker Project, the sample for this study included respondents who experienced the death of an immediate family member - father, mother, spouse, sibling, or child - within a year before the Biomarker project and those who did not experience any deaths (N = 962). We used two measures of HRV and sleep quality was measured using the Pittsburgh Sleep Quality Index. Results showed that experiencing the death of a family member was associated with worse HRV only among those with poor sleep quality and not for those with good sleep quality. These results suggest that poor sleep quality may indicate psychophysiological vulnerability for those who experienced the death of a family member. Interventions to improve sleep quality could be effective in enhancing cardiovascular health of bereaved individuals.

Factors Associated With Working Caregivers' Well-Being: Comparisons Between Black and White Working Caregivers in the United States.

This study investigated stressors and strains, resources, and well-being among Black working caregivers (BWC) and White working caregivers (WWC) who participated in the Midlife in the United States study (Black: n = 49, White: n = 250). Comparisons were made between BWC and WWC for primary caregiving stressors, secondary strains, resources, and well-being, and hierarchical regression models tested associations among these factors. BWC reported less negative work-to-family spillover, more perceived control and religious/spiritual coping, and higher positive affect than WWC, complementing existing evidence of greater resilience among BWC. Secondary strains stemming from the workplace had stronger associations with well-being than primary caregiving stressors, confirming that the workplace deserves greater attention in stress research and interventions for working caregivers. Finally, perceived control, optimism, and family support were important resources for well-being for both BWC and WWC, substantiating their valuable role in interventions for working caregivers.

Diversity of daily activities is associated with greater hippocampal volume.

Greater engagement in a range of daily activities is associated with better cognitive functioning (Lee et al., Lee et al., 2020). The hippocampus, a subcortical brain structure implicated in learning, memory, spatial navigation and other aspects of cognitive functioning, may be structurally sensitive to exposure to and engagement with novel experiences and environments. The present study tested whether greater activity diversity, defined as the range of common daily activities engaged in and the proportion of time spent in each, is associated with larger hippocampal volume. Greater diversity of activities, as measured using daily diaries across an 8-day period, was related to greater hippocampal volume averaged across the left and right hemispheres, even when adjusting for estimated intracranial volume, total activity time, sociodemographic factors, and self-reported physical health. These findings are broadly consistent with nonhuman animal studies, demonstrating a link between enriched environments and structural changes to the hippocampus. Future longitudinal and experimental work can elucidate causal and directional relationships between diversity of daily activities and hippocampal volume.

Daily associations between sleep and stressors in nurses with and without children.

Previous research shows that adults with children have poorer sleep overall than adults without children. Poorer sleep is associated with experiencing more frequent and severe stressors. The daily link between sleep and stressors may differ by parenting status; yet this potential difference has not been addressed, especially in nurses who provide care both at work and home. This study examined whether the sleep-stress relationship is stronger for nurses with children than those without. During 14 days of ecological momentary assessment, 60 hospital nurses (24 parents) reported their previous night's sleep characteristics upon waking. Three times daily, they also reported whether they encountered any stressors and how severe those stressors were. Associations were assessed at the within- and between-person levels with parenting status as a between-person moderator. After controlling for covariates, previous night's poorer sleep quality, lower sleep sufficiency, and shorter time in bed were associated with perceiving more frequent or severe stressors the following day. Some of these daily associations were moderated by parenting status, such that the sleep-stressor link was only significant for parents, with the magnitude of association being stronger for those with 2+ children relative to 1 child. These findings suggest that nurses with children are at greater risk for a stronger linkage between poorer sleep and greater stressor frequency and severity. A stronger sleep-stressor relationship could have compounding effects on health. Improving sleep in this group may be critical to reduce their stress and improve the quality of care across work and home.

Naturally Occurring Consecutive Sleep Loss and Day-to-Day Trajectories of Affective and Physical Well-Being.

BACKGROUND: Experimental studies have shown that just 1 night of sleep loss impairs next-day performance, mood, and energy. Yet, little is known about the effects of consecutive sleep loss on daily well-being in participants' own settings. PURPOSE: This study examined whether and how naturally occurring consecutive sleep loss is associated with day-to-day trajectories of affective and physical well-being. METHODS: Participants were adults (N = 1,958) from the Midlife in the United States Study who provided daily diary data for eight consecutive days. Consecutive sleep loss was operationalized as the within-person number of consecutive nights with <6 hr of sleep. Multilevel models evaluated the linear, quadratic, and cubic effects of consecutive sleep loss on daily well-being, after controlling for sociodemographic, health, and daily covariates. RESULTS: Daily negative affect increased and positive affect decreased in curvilinear fashion as the number of consecutive sleep loss increased. For example, daily negative affect increased (linear), but the rate of increase decelerated as the number of consecutive sleep loss increased (quadratic). Results were consistent for the number and severity of physical symptoms. For negative affect and the severity of physical symptoms, cubic effect was also significant such that the rate of increase accelerated again in the days most distal to baseline (no sleep loss). CONCLUSIONS: Consecutive sleep loss was associated with degraded trajectories of daily affective and physical well-being. Making efforts to break the vicious cycle of sleep loss may protect daily well-being in adults whose sleep time is often compromised.

Adapting Research to a Global Pandemic: A Fully Remote Actigraphy and Ecological Momentary Assessment Study.

BACKGROUND: Mandated social distancing practices and quarantines in response to COVID-19 have resulted in challenges for research on healthcare workers, such as hospital nurses. It remains unknown whether nursing studies utilizing complex methodology like sleep actigraphy and ecological momentary assessment (EMA) can be conducted remotely without compromising data quality. OBJECTIVES: We aimed to (a) disseminate our remote study protocol for sleep actigraphy and EMA data from hospital nurses during COVID-19, (b) assess feasibility and acceptability of this approach for studies on hospital nurses, and (c) examine the reliability and ecological validity of sleep characteristics measured across 14 days. METHODS: Using an online platform, we provided 86 outpatient nurses from a cancer hospital with detailed video/text instructions regarding the study and facilitated virtual study onboarding meetings. Feasibility was assessed by comparing adherence rates to a similar in-person study of nurses from the same hospital; acceptability was evaluated through content analysis of qualitative study feedback. Multilevel modeling was conducted to assess changes in sleep characteristics as a function of study day and daily stressful experiences. RESULTS: Adherence to EMA (91.8%) and actigraphy (97.9%) was high. EMA adherence was higher than the in-person study of inpatient day-shift nurses from the same hospital. Content analyses revealed primarily positive feedback, with 51.2% reporting "easy, clear, simple onboarding" and 16.3% reporting the website was "helpful." Six participants provided only negative feedback. Sleep characteristics did not change as a function of study day except for self-reported quality, which increased slightly during Week 1 and regressed toward baseline after that. A higher incidence of stressor days or higher stressor severity followed nights with shorter-than-usual time in bed or poorer-than-usual sleep quality, supporting the ecological validity for these methods of assessing sleep in nurses. DISCUSSION: Findings suggest that a fully remote study protocol for EMA and actigraphy studies in nursing yields robust feasibility, acceptability, reliability, and validity. Given the busy schedules of nurses, the convenience of this approach may be preferable to traditional in-person data collection. Lessons learned from COVID-19 may apply to improving nursing research postpandemic.

Subjective social status moderates back pain and mental health in older men.

OBJECTIVES: Back pain and poor mental health are interrelated issues in older men. Evidence suggests that socioeconomic status moderates this relationship, but less is known about the role of subjective social status (SSS). This study examined if the association between back pain and mental health is moderated by SSS. METHOD: We used a sample of community-dwelling older men (≥65 years) from the Osteoporotic Fractures in Men Study (N = 5994). Participants self-reported their back pain severity and frequency over the past 12 months. SSS was assessed with the MacArthur Scale of SSS. Mental health was assessed with the SF-12 Mental Component Summary (MCS). RESULTS: Severe back pain was associated with lower SF-12 MCS scores (p = .03). Back pain frequency was not associated with SF-12 MCS scores. SSS moderated the back pain and mental health relationship. Among men with higher national or community SSS, the association between back pain severity and SF-12 MCS scores was not significant. However, among men with lower national or community SSS, more severe back pain was associated with lower SF-12 MCS scores (p's < .001). Among those with lower national or community SSS, greater back pain frequency was also associated with lower SF-12 MCS scores (p's < .05). CONCLUSION: Where one ranks oneself within their nation or community matters for the back pain and mental health relationship. Higher SSS may be a psychosocial resource that buffers the negative associations of severe and frequent back pain on mental health in older men.

Resource-Building Processes Across Life Domains: Father-Child Interactions as Starting Points for Resource Caravans.

In two studies, we examined preconditions of resource-building processes between family and work. Focusing on positive father-child interactions, we investigated positive mood states as links between the two life domains. Fathers employed in information technology (N 1 = 59) and the retail sector (N 2 = 75) participated in micro-longitudinal studies, both for eight consecutive workdays. Study 1 revealed that fathers with more positive interactions with a child also reported more positive mood states and fathers with more positive mood states perceived more social resources from their supervisor during the week. The indirect effect was small but significant. In Study 2, multilevel structural-equation models did not find indirect effects at the within-person level but did show that positive father-child interactions after work were related to fathers' positive mood states before going to bed and positive mood in the morning predicted perceived social resources from supervisors (but not from coworkers) in the forenoon. There were also positive effects of perceived social resources from supervisors on positive mood states, after work. But these did not translate into an increase in positive father-child interactions, in the evening. Hence, only single elements were supported but not the overall resource caravan.

Subjective cognitive abilities correlate with poor sleep among day-shift and night-shift nurses.

Experimental studies have shown that sleep deprivation may lead to worse performance on cognitive tests. However, few studies have considered how sleep is associated with perceived cognitive performance in the daily lives of hospital nurses who require high cognitive abilities to deliver high-quality patient care. The current study examined the relationship between sleep and subjective cognition in nurses, and whether the relationship differed by work shift and workdays. Sixty in patient nurses working full-time (M = 35 years; 39 day-shift nurses, 21 night-shift nurses) reported their sleep characteristics and daily subjective cognition using ecological momentary assessment for 14 days. Concurrently, objective sleep characteristics were measured with a sleep actigraphy device for 14 days. Using multilevel modelling, results indicated that at the within-person and between-person level, better sleep quality and higher sleep sufficiency were associated with better subjective cognition at the daily-level and on average. Moderation analyses indicated at the within-person level, better sleep quality and longer time in bed were associated with better next-day cognition; these associations were stronger for night-shift nurses compared with day-shift nurses. At the between-person level, better sleep quality and higher sleep sufficiency were also associated with better subjective cognition overall; these associations were significant for day-shift nurses, but not for night-shift nurses. The sleep-subjective cognition relationships were more apparent on workdays versus non-workdays. Findings suggest that sufficient sleep recovery is important for nurses' reports of daily and overall cognitive functioning. Night-shift nurses' subjective cognitive abilities may be more protected on days following better sleepquality and more sufficient sleep.

Individual and joint associations of daily sleep and stress with daily well-being in hospital nurses: an ecological momentary assessment and actigraphy study.

Sleep and stress are predictors of daily physical and emotional well-being, but few studies assess both simultaneously. This study examined individual and joint associations of daily sleep and stress with daily well-being (DWB) in hospital nurses. Nurses (n = 60) participated in a 14-day ecological momentary assessment and actigraphy study. Multilevel modeling revealed associations of stressor severity and poor sleep health with DWB, independent of and coupled with each other, at within- and between-person levels. Greater stressor severity or poorer sleep health, independent of each other, were associated with more physical symptoms, less positive affect (PA), and more negative affect (NA). Joint associations of stress and sleep with DWB were observed: PA was lowest when higher stressor severity was coupled with poorer sleep health; NA was lowest when lower stressor severity was coupled with better sleep health. Findings suggest the importance of considering both sleep and stress for DWB in hospital nurses.

Disentangling the Relationship between Food Insecurity and Poor Sleep Health.

The COVID-19 pandemic has created disruptions in global and national food supply chains. Along with an increase in the unemployment rate, this resulted in a rise in food insecurity at the community-level, threatening individual and family well-being. Food insecurity is associated with inadequate nutrient intakes, weight gain, and psychological distress, including anxiety and depressive symptoms, all of which are known to affect sleep. Yet, little is known about whether and how food insecurity is associated with sleep health, a critical but underrecognized health outcome. This paper reviews literature describing associations between food insecurity and sleep, summarizes key findings based on proposed mechanisms, and discusses directions for future research.

Various Types of Perceived Job Discrimination and Sleep Health Among Working Women: Findings From the Sister Study.

Job discrimination, a social stressor, may lead to sleep health disparities among workers; yet, limited research has examined this relationship and specific sources of job discrimination. We used a US sample of working women (n = 26,085), participants in the Sister Study (2008-2016), to examine the associations of perceived job discrimination due to sex, race, age, health conditions, and/or sexual orientation with sleep health. Cross-sectionally, linear or logistic regression models revealed that each source of job discrimination was independently associated with different sleep problems after controlling for other sources of job discrimination. Longitudinally, among participants without short sleep (<7 hours/night) at time 1 (2012-2014), age-specific job discrimination was associated with 21% increased odds of new-onset short sleep (odds ratio = 1.21, 95% confidence interval: 1.03, 1.43) at time 2 (2014-2016). Among those without insomnia symptoms at time 1, race-specific job discrimination was associated with 37% increased odds of new-onset insomnia symptoms (odds ratio = 1.37, 95% confidence interval: 1.07, 1.75) at time 2. Sex- and health-specific job discrimination also predicted new-onset sleepiness. There were dose-response relationships such that a greater number of sources of job discrimination (≥3) was associated with greater odds of prevalent and incident sleep problems. Perceived job discrimination may contribute to working women's poor sleep health over time, raising concerns about sleep health disparities emanating from the workplace.

Stressor reactivity to insufficient sleep and its association with body mass index in middle-aged workers.

There is evidence that insufficient sleep and more stressors are individually associated with poor metabolic health outcomes. Examining sleep and stressors jointly may account for greater variability in health outcomes; however, we know little about the combined effect of both insufficient sleep and more stressors on metabolic health. This study examined whether experiencing more stressors in response to insufficient sleep ("stressor reactivity to insufficient sleep") was associated with body mass index in middle-aged workers. One-hundred and twenty-seven participants (Mage  = 45.24 ± 6.22 years) reported nightly sleep characteristics and daily stressors on 8 consecutive days. We collected height and weight measurements to calculate body mass index (kg m-2 ). On average, workers reported more stressors following nights with shorter-than-usual sleep duration or poorer-than-usual sleep quality (negative slope means higher stressor reactivity to insufficient sleep). When examining stressor reactivity to insufficient sleep with insufficient sleep represented by shorter-than-usual sleep duration, compared with those with average stressor reactivity to insufficient sleep (within ±½ SD; reference), workers with high stressor reactivity to insufficient sleep (≤-½ SD) had higher body mass index (B = 3.24, p < .05). The body mass index of these workers fell in the obese range. There was no difference in body mass index between workers with low stressor reactivity to insufficient sleep (≥+½ SD) and the reference group. When examining stressor reactivity to insufficient sleep with insufficient sleep represented by poorer-than-usual sleep quality, stressor reactivity to insufficient sleep was not significantly associated with body mass index. Results suggest that middle-aged workers with higher stressor reactivity to insufficient sleep duration may be at greater risk for obesity. Results may inform future studies on interventions for improving sleep and reducing stress in middle-aged workers.

Cognitive deficits in Parkinson's disease with excessive daytime sleepiness: a systematic review.

Objectives: This systematic review synthesizes the most recent literature on neuropsychological deficits in adults with Parkinson's disease who experience excessive daytime sleepiness (EDS). Confounds and methodological limitations are explored. A framework entitled the Cascade Model of Excessive Daytime Sleepiness (CMEDS) is proposed to explain the role of EDS in contributing to cognitive impairment for patients with Parkinson's disease.Method: Systematic search through PubMed, PsychInfo and citation records. In total, 175 articles were screened for possible inclusion. Eight studies were included, encompassing 1373 patients with Parkinson's disease - 442 of whom had Parkinson's disease with EDS.Results: For Parkinson's disease patients with EDS, global deficits, executive dysfunction and deficits in processing speed were found beyond the typical cognitive phenotype of patients without EDS. Language skills, memory and visuospatial skills appeared to be similar between those with and without EDS. In untreated, de novo, patients, there were no cognitive differences between the EDS groups.Conclusion: This review suggests that Parkinson's disease patients suffering from EDS may have additional cognitive deficits globally, in executive control, and in processing speed. As suggested by the CMEDS framework, the impact of EDS on cognition may be related to Parkinson's disease pathology, comorbidities and medication use.

What's not fair about work keeps me up: Perceived unfairness about work impairs sleep through negative work-to-family spillover.

This study examined whether perceived unfairness about work was linked to midlife workers' insomnia symptoms over time, and if the association was mediated by negative work-to-family spillover (NWFS). We used 3 waves of longitudinal data across 20 years from the Midlife in the United States Study (N = 971, Mage = 40.52). Results revealed that, wave-to-wave increases in perceived unfairness about work predicted wave-to-wave increases in NWFS over 20 years. Wave-to-wave increases in NWFS, in turn, predicted wave-to-wave increases in insomnia symptoms. Perceived unfairness about work was indirectly, but not directly associated with insomnia symptoms through NWFS. These within-person indirect mediation pathways were found after controlling for sociodemographic and family characteristics, work hours, neuroticism, physical health, and between-person associations between perceived unfairness about work, NWFS, and insomnia symptoms. These findings suggest that perceived unfairness about work may degrade workers' sleep health over time, through the spillover of work stress to the personal domain.

Daily antecedents and consequences of nightly sleep.

Sleep can serve as both cause and consequence of individuals' everyday experiences. We built upon prior studies of the correlates of sleep, which have relied primarily on cross-sectional data, to examine the antecedents and consequences of sleep using a daily diary design. Specifically, we assessed the temporal sequence between nightly sleep and daily psychosocial stressors. Parents employed in a US information technology company (n = 102) completed eight consecutive daily diaries at both baseline and 1 year later. In telephone interviews each evening, participants reported on the previous night's sleep hours, sleep quality and sleep latency. They also reported daily work-to-family conflict and time inadequacy (i.e. perceptions of not having enough time) for their child and for themselves to engage in exercise. Multi-level models testing lagged and non-lagged effects simultaneously revealed that sleep hours and sleep quality were associated with next-day consequences of work-to-family conflict and time inadequacy, whereas psychosocial stressors as antecedents did not predict sleep hours or quality that night. For sleep latency, the opposite temporal order emerged: on days with more work-to-family conflict or time inadequacy for child and self than usual, participants reported longer sleep latencies than usual. An exception to this otherwise consistent pattern was that time inadequacy for child also preceded shorter sleep hours and poorer sleep quality that night. The results highlight the utility of a daily diary design for capturing the temporal sequences linking sleep and psychosocial stressors.
