RESUMO
OBJECTIVE: Abundant research has linked nightly sleep as an antecedent of daily psychosocial experiences; however, less is known about sleep's influence on daily expectations of these experiences. Therefore, this research examined the day-to-day associations of sleep quality, duration, and efficiency with next-day expectations for stress(ors) and positive experiences, as well as whether these expectations were related to end-of-day reports of physical symptoms. METHODS: In Study 1, U.S. adults ( n = 354; ages 19 to 74) completed twice-daily diaries for 10 weekdays about sleep, expectations for encountering daily stressors and positive events, and physical symptoms. In Study 2, adults in Canada ( n = 246; ages 25 to 87) wore a sleep watch for 14 consecutive days and completed mobile surveys 5×/day about sleep, stressfulness and pleasantness expectations, and physical symptoms. RESULTS: Multilevel models indicated that self-reported sleep quality and duration, but not efficiency, were associated with lower next-day expectations for stressors (Study 1) and stressfulness (Study 2). Self-reported sleep quality (Study 1) and all sleep indices (Study 2) predicted greater next-day expectations for positive events and pleasantness, respectively. For actigraphy-assessed sleep (Study 2), only longer-than-usual actigraphic sleep duration was associated with lower stressfulness expectations, whereas both sleep duration and efficiency were positively linked with daily pleasantness expectations. Only pleasantness expectations (Study 2)-but not daily stressfulness and event expectations (Study 1)-predicted end-of-day physical symptoms. CONCLUSION: Findings suggest the importance of sleep on expectations of next-day stress and positive experiences, of which may have implications for daily physical health.

OBJECTIVE: Shorter sleep duration and more sleep disturbances, in addition to greater night-to-night fluctuations in sleep (intraindividual variability; IIV), have been associated with elevated inflammation. However, these associations were only at the between-person level. The current study examined the within-person relationship between mean levels and IIV of sleep duration and sleep disturbances and C-reactive protein (CRP) in healthy, aging women. METHODS: Participants ( N = 179) from a longitudinal study of activity and well-being in middle-aged and older women (mean age = 62 years; range = 50-75 years) completed a 7-day daily diary, every 3 months, for 2 years (up to nine bursts). Sleep was assessed each day asking participants how many hours of sleep they got the night before and with the four-item PROMIS Sleep Disturbance Short Form. Finger-stick dried blood spot samples were collected after each 7-day daily diary. RESULTS: In bursts when women experienced greater than average variability in sleep duration, they had higher CRP ( γ = 0.06, p = .004). Within-person changes in mean sleep duration were not associated with CRP. In addition, neither mean sleep disturbances nor sleep disturbance IIV were associated with CRP. CONCLUSIONS: This study is the first to show that within-person changes in variable sleep duration are related to changes in inflammation. Findings from the current study suggest that greater variability in sleep duration is related to higher CRP, which may increase risk for early morbidity and mortality. Future studies should investigate inflammation as a pathway linking sleep variability and health.

Researchers hypothesize that how people react to daily stressful events partly explains the relationship between personality and health, yet no study has examined longitudinal associations between these factors. The current study focused on the role of negative affect reactivity to daily stressful events as a mediating pathway between personality and physical health outcomes using three waves of data spanning 20 years from a nationwide probability sample of 1,176 adults. Results indicated that negative affect reactivity partially mediated personality and physical health. Wave 1 neuroticism was associated with greater negative affect reactivity at Wave 2, which predicted the development of chronic conditions and functional limitations at Wave 3. Higher conscientiousness at Wave 1 was associated with less negative affect reactivity at Wave 2, which predicted better physical health at Wave 3. These findings highlight the usefulness of using a daily-stress framework for understanding how personality impacts health over time, which has important implications for stress management and disease prevention.

BACKGROUND: Disturbed sleep is prevalent in older adulthood and particularly among women. Greater psychological well-being (PWB) is associated with better sleep, but intraindividual variability in PWB has not been examined. PURPOSE: The current study examined whether mean levels and variability in PWB were associated with sleep disturbances in midlife and older women. METHODS: Participants (N = 189) completed up to seven daily diaries and an end of the week assessment every 3 months for nine waves. Participants answered questions about their nightly sleep disturbances and reported their PWB using Ryff's six dimensions of PWB. RESULTS: Regression models indicated that greater variability in one aspect of PWB, positive relations with others, was related to greater sleep disturbance even after adjusting for mean levels of well-being. Greater variability in environmental mastery, purpose in life, and self-acceptance were also associated with sleep disturbance, but these associations were no longer significant after adjusting for mean levels of well-being. CONCLUSIONS: Results suggest that fluctuations in positive relations with others are related to sleep in adult women above and beyond mean levels of well-being. Results highlight the importance of considering variability in addition to mean levels of PWB.

The way we respond to life's daily stressors has strong implications for our physical health. Researchers have documented the detrimental effects of initial emotional reactivity to daily stressors on future physical health outcomes but have yet to examine the effects of emotions that linger after a stressor occurs. The current study investigated how negative affect that lingers the day after a minor stressor occurs is associated with health-related outcomes. Participants ( N = 1,155) in a community-based, nationwide study answered questions about daily stressors and affect across 8 consecutive days and about their physical health almost 10 years later. Multilevel models indicated that people experience heightened levels of negative affect the day after a stressor occurs. Furthermore, higher levels of lingering negative affect are associated with greater numbers of chronic conditions and worse functional limitations 10 years later. Findings suggest that affective recovery from daily stressors has unique importance for long-term physical health.

RATIONALE: How individuals regulate their emotions is critical for maintaining health and well-being. For example, reframing a stressful situation in a positive light, a form of cognitive reappraisal, is beneficial for both physical and mental health as well as subjective well-being. However, it is currently unclear why this relationship exists. One potential mechanism could be how one emotionally reacts to stressors in daily life, termed affective reactivity. OBJECTIVE: The current study examined longitudinal associations that spanned 20 years between cognitive reappraisal and health outcomes and subjective well-being and if affective reactivity mediated this relationship. METHODS: Participants completed waves 1-3 of the Midlife in the United States (MIDUS) Survey series and were asked various questions about their general health and well-being. Each wave was approximately 10 years apart. A subset of participants from MIDUS II completed the National Study of Daily Experiences (NSDE II), an 8-day daily diary asking about their everyday experiences. The final sample consisted of 1814 participants. RESULTS: Results found that cognitive reappraisal was significantly associated with future health and well-being outcomes, and negative affective reactivity significantly mediated this relationship. Those who engaged more in cognitive reappraisal tended to be less affectively reactive to stressful events 10 years later, leading to having better health and well-being outcomes 20 years later. CONCLUSION: Findings from this study could better inform stress and well-being interventions by strengthening cognitive reappraisal strategies to target reducing affective reactivity to stressors which should then benefit long-term health and well-being.

OBJECTIVE: Perseverative thinking (e.g., worry/rumination) is a common response to stress, and can be detrimental to well-being. Sleep may represent an important mechanism by which perseverative thinking is disrupted or amplified from day to day. This study examined the associations between older adults' everyday worry, rumination, and sleep. METHODS: Older adults (N = 270) aged 65-89 completed a baseline interview and morning and evening assessments each day for 5-6 days. Every morning, they indicated their worry toward the day and their sleep duration and disturbances the prior night. Every evening, they rated worry and rumination experienced that day. RESULTS: Multilevel models showed that perseverative thinking predicted worse sleep (i.e., fewer hours of sleep) at the between-person level (B = -0.29, p = .004) but better sleep (i.e., fewer sleep disturbances) at the within-person level (Bs < -0.18, ps < .003). At the within-person level, more hours of sleep (B = -0.06, p = .04) and fewer sleep disturbances (B = 0.10, p < .001) predicted less worry the next morning. Prior night's worry predicted greater next morning's worry, but this association was significant only when older adults reported fewer-than-usual hours of sleep (B = 0.24, p < .001), not when they reported more-than-usual hours of sleep (B = 0.04, p = .61). CONCLUSION: Findings suggest that worry and rumination are intimately linked with sleep and highlight the protective role that better sleep may play in reducing older adults' everyday perseverative thinking.

OBJECTIVES: Daily electronic media use, including television viewing and computer use, is common in older adulthood. Yet, increased electronic media usage may disrupt nightly sleep, leading to sleeping fewer hours and more sleep disruptions. The current study examined these relationships in older adulthood, as well as the potential buffering effect of having a regular sleep schedule. METHODS: Older adults (Nâ =â 273) from the Daily Experiences and Well-Being Study (DEWS) completed 5-6 days of data collection where they answered questions at the beginning of the day about the previous night's sleep as well as questions throughout the day about daily electronic media use. They also wore Actical accelerometers to capture sleep regularity. RESULTS: Older adults reported sleeping fewer hours and having more sleep disturbances on days when they reported more instances of computer use. Sleep regularity moderated the daily association between TV viewing and sleep disturbances such that daily TV viewing was associated with more sleep complaints only for older adults who had less regular sleep patterns. However, sleep regularity no longer moderated this association when accounting for napping behavior. DISCUSSION: These findings provide evidence that older adults sleep worse after days when they engage in more electronic media use. The association with TV viewing with sleep disturbances on any given day is somewhat mitigated by engaging in regular sleep patterns. Researchers discuss the importance of assessing electronic media use and sleep in daily life as the role of sleep regularity may be a modifiable protective factor.

BACKGROUND: The COVID-19 pandemic has had drastic effects on K-12 teachers. Researchers partnered with a teacher advisory board to identify factors associated with K-12 teachers' consideration of leaving teaching during Fall 2020. METHODS: A web-based survey focused on teachers' working experiences was emailed to school union membership listservs in Indiana, Kentucky, and Ohio. A logistic regression model was developed to identify working conditions associated with teachers considering leaving the profession. RESULTS: Among 5873 K-12 teachers, 27% (n = 1319) were considering leaving the profession either because of COVID-19 (10%), for other reasons (6%) or were undecided (11%). Teachers who were midcareer, having taught 6-10 years, who perceived less supervisor support, whose job duties had changed significantly, who were dissatisfied with the COVID-19 related decision-making, who reported poor or fair mental health, and who were mostly or extremely afraid that a household member would get COVID-19 had higher odds of considering leaving teaching or being undecided about future career plans. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE AND EQUITY: Understanding factors influencing teachers' career decisions will help school leaders improve teacher retention amid challenging circumstances. CONCLUSION: In this study in 3 midwestern US states, limited supervisor support, significant job duty change, dissatisfaction with COVID-19-related decision-making, poor or fair mental health, and fear that a household member would get COVID-19 were associated with teachers' consideration of leaving the profession or being undecided about future career plans.

OBJECTIVES: Older adults who are physically active report lower levels of stress. Less is known about the links between physical activity and exposure and reactivity to stressful events in daily life. The current study examined within-person associations between actigraphy-assessed daily physical activity and exposure and affective reactivity to naturally occurring interpersonal stressors. METHOD: Older adults (Nâ =â 180) from the Daily Experiences and Well-being Study completed ecological momentary assessments (EMAs) every 3 hr for 5-6 days where they reported negative affect throughout the day and interpersonal tensions at the end of the day. They also wore Actical accelerometers to capture physical activity. RESULTS: Older adults reported greater numbers of interpersonal stressors on days when they spent less time being sedentary and engaged in more light physical activity. On days when older adults experienced more interpersonal stressors, they reported higher levels of negative affect, but this association was attenuated when they were more physically active that day. DISCUSSION: Physical activity may bolster older adults' capabilities to manage affective responses to interpersonal stressors in a more successful way. These findings underscore the importance of assessing physical activity and stressful events in daily life and have implications for both physical and psychological well-being.

ABSTRACTSmiling has been a topic of interest to psychologists for decades, with a myriad of studies tying this behavior to well-being. Despite this, we know surprisingly little about the nature of the connections between smiling and physical health. We review the literature connecting both naturally occurring smiles and experimentally manipulated smiles to physical health and health-relevant outcomes. This work is discussed in the context of existing affect and health-relevant theoretical models that help explain the connection between smiling and physical health including the facial feedback hypothesis, the undoing hypothesis, the generalized unsafety theory of stress, and polyvagal theory. We also describe a number of plausible pathways, some new and relatively untested, through which smiling may influence physical health such as trait or state positive affect, social relationships, stress buffering, and the oculocardiac reflex. Finally, we provide a discussion of possible future directions, including the importance of cultural variation and replication. Although this field is still in its infancy, the findings from both naturally occurring smile studies and experimentally manipulated smile studies consistently suggest that smiling may have a number of health-relevant benefits including beneficially impacting our physiology during acute stress, improved stress recovery, and reduced illness over time.

Historically, studies of childhood and adult resilience have typically focused on adaptation to chronic life adversities, such as poverty and maltreatment, or isolated and potentially traumatic events, such as bereavement and serious illness. Here, we present a complementary view and suggest that stressors experienced in daily life may also forecast individual health and well-being. We argue that daily process approaches that incorporate intensive sampling of individuals in natural settings can provide powerful insights into unfolding adaptational processes. In making this argument, we review studies that link intraindividual dynamics with diverse health-related phenomena. Findings from this research provide support for a multiple-levels-analysis perspective that embraces greater unity in pivotal resilience constructs invoked across childhood and adult literatures. Drawing on insights and principles derived from life-span theory, we conclude by outlining promising directions for future work and considering their broader implications for the field of resilience.

OBJECTIVE: Exposure to discrimination is consistently linked with worse physical and mental health outcomes. One potential reason is that discriminatory experiences shape the way people interpret and affectively react to daily stressful events which in turn impacts health. The current study examined the role of these two daily psychological stress processes as a pathway linking the longitudinal association between perceived discrimination and health outcomes. METHOD: Participants in the National Study of Daily Experiences (NSDE), a subset of the Midlife in the United States (MIDUS) study, were followed over three waves spanning 20 years (N = 1,315). Perceptions of lifetime and everyday discrimination were measured by questionnaire at Wave 1; daily assessments of stress, threat appraisals, and negative affect were assessed through 8 days of daily dairies at Wave 2; measures of physical health (chronic conditions, functional limitations, and self-rated physical health) and mental health (depression, anxiety, and self-rated mental health) were assessed at Wave 3. Each wave of data was collected 9-10 years apart. RESULTS: Lifetime and everyday discrimination were associated with worse physical and mental health outcomes 20 years later. Daily threat appraisals and negative affective reactivity to daily stressors mediated the effect of discrimination on physical and mental health. CONCLUSION: Daily psychological stress processes are a potential mechanism by which exposure to unfair treatment relates to health. Findings underscore the insidious nature of unfair treatment and demonstrate how such experiences may be particularly consequential for daily stress processes and later physical and mental health outcomes.

Heightened affective and physical reactions to daily stressful events predict poor long-term physical and mental health outcomes. It is unknown, however, if an experimental manipulation designed to increase interpersonal resources at work can reduce associations between daily stressors and physical and affective well-being. The present study tests the effects of a workplace intervention designed to increase supervisor support for family and personal life and schedule control on employees' affective and physical reactivity to daily stressors in different domains (i.e., work, home, interpersonal, and noninterpersonal stressors). Participants were 102 employed parents with adolescent children from an information technology (IT) division of a large U.S. firm who participated in the Work, Family, and Heath Study. Participants provided 8-day daily diary data at baseline and again at a 12-month follow-up after the implementation of a workplace intervention. Multilevel models revealed that the intervention significantly reduced employees' negative affect reactivity to work stressors and noninterpersonal stressors, compared to the usual practice condition. Negative reactivity did not decrease for nonwork or interpersonal stressors. The intervention also did not significantly reduce positive affect reactivity or physical symptom reactivity to any stressor type. Results demonstrate that making positive changes in work environments, including increasing supervisor support and flexible scheduling, may promote employee health and well-being through better affective responses to common daily stressors at work.

Concurrent and retrospective reports correspond for personality, affect, and coping. The present study described how autonomy, competence, and relatedness components of eudaemonic well-being (EWB) change over days and months and tested correspondences of daily and retrospective reports between and within people. Midlife and older (50-75 years) women (N = 200) completed online diaries daily for 1 week for 9 bursts over 2 years and answered questionnaires at the end of each burst (burst n = 1,529). Multilevel models partialed levels of variance and tested correspondence. Women varied in their daily experiences of EWB but did not vary substantially between bursts. Burst-level diary means and questionnaire responses corresponded between people, but changes within people were less strongly related. The daily, but not monthly, time scale of change is important for capturing within-person changes in EWB. Finding EWB change over months to years may depend on measurement designed to capture medium-term change.
RESUMO
INTRODUCTION: To slow the spread of COVID-19 in the United States, businesses shutdown in Spring 2020. Research has indicated the impact on frontlines workers, yet little is known about the impact on those who were not working outside the home or switched to working remotely. PURPOSE: The purpose of this report is to identify the financial and healthcare issues and mental health impact of the COVID-19 shutdown on Appalachians by worker categories. METHODS: An online survey was administered from May 8 - June 6, 2020 to a convenience sample of previous research participants and shared through social media networks, i.e., snowball sampling. Questions investigated mental health, financial and healthcare issues, and employment status. Survey responses were summarized by percentages overall and by working categories. RESULTS: Of the 751 participants, 276 (42%) resided in Appalachia. After removing 17 who lost their job due to COVID-19, 59 (23%) indicated not working outside the home prior to COVID-19, whereas 111 (43%) and 89 (34%) switched to working remotely and continued working outside the home during the shutdown. Respondents were predominately Caucasian and female. Nearly a quarter of participants had lost or reduced income due to the shutdown. Approximately half missed or postponed healthcare appointments. Mental health impacts were similar across the groups, with half of the respondents reporting anxiety due to COVID-19. IMPLICATIONS: Further research is needed to explore health outcomes associated with missed healthcare appointments during the shutdown. Mental health support may be needed equally by those isolated at home and frontline workers.
RESUMO
RATIONALE: Work is a common source of stress for many adults, arising from situations that occur at work (e.g., job demands) as well as the worries and responsibilities that people take home with them (negative work-family spillover). Over time, work-related stress may impact physical health. OBJECTIVE: The current study prospectively examined the effects of job demands and negative work-family spillover (NWFS) on three self-reported physical health measures. METHOD: Participants in the Midlife in the United States (MIDUS) survey (N = 4200) reported their job demands and negative work-family spillover at wave 1. They also reported on their health across three waves of data collection. RESULTS: Higher levels of NWFS at baseline were related to a higher number of self-reported chronic illnesses, greater functional limitation, and poorer self-rated health approximately 10 and 20 years later. In contrast, job demands were unrelated to any health indices at baseline or at the approximately 10- and 20-year follow-ups. CONCLUSIONS: Findings suggest that NWFS is a unique form of stress with long-lasting and detrimental effects on physical health.

Good sleep habits are important for emotional well-being. Studies have linked sleep with people's ability to regulate their emotions in response to stressful events, yet little is known specifically about how sleep is related to a person's ability to recover affectively from a stressful experience. The current study examined self-reported sleep habits and their associations with both positive and negative affective recovery from a laboratory-induced stressor. Participants (N = 120) reported their sleep habits over the previous month and then engaged in a laboratory psychosocial stress task. Affect was measured before, during, and 6 minutes after the task. Different aspects of sleep were related to poorer positive and negative affective recovery. Worse sleep quality was associated with higher post-recovery negative affect, whereas worse sleep efficiency was associated with lower post-recovery positive affect. Findings suggest that poor sleep is associated with prolonged affective recovery from a stressful event. Implications for health and well-being are discussed.

Positive emotions help us during times of stress. They serve to replenish resources and provide relief from stressful experiences. Positive emotions may be particularly beneficial during times of stress by dampening negative emotional reactivity and quickening recovery from stressful events. In this study, we used a daily diary design to examine how positive emotions experienced on days with minor stressful events are associated with same day and next day stressor-related negative emotions. We combined data from the National Study of Daily Experiences II (NSDE II) and the Midlife in the United States survey (MIDUS II), resulting in 1,588 participants who answered questions about daily stressors and emotion across 8 consecutive days. On days when people experienced a stressor and had higher than their average level of positive emotion, they experienced less of a same day increase in negative emotion. Additionally, they experienced less subsequent negative emotion the following day and were less likely to experience a stressor the next day. Results held when adjusting for trait measures of positive and negative emotion. These results suggest that daily positive emotions experienced on days of stress help regulate our negative emotion during times of stress.
RESUMO
OBJECTIVES: Many studies have documented the strong associations between well-being and mean levels of both positive and negative affect. A growing number of studies are examining how fluctuations in daily reported emotional experience, known as affect variability, is related to health outcomes. Sleep is a critical correlate of healthy in functioning in late life. This study examines associations between positive and negative affect variability and facets of self-reported sleep behavior among older adults. METHODS: Participants (Nâ¯=â¯277) completed a 5 to 6â¯day ecological momentary assessment. The first survey upon waking asked participants about their sleep the previous night, and participants rated their positive and negative affect every three subsequent hours during waking hours. RESULTS: Regression models indicate that greater variability in daily positive affect is associated with fewer hours of sleep (bâ¯=â¯-0.648, pâ¯=â¯.04) and greater morning tiredness (bâ¯=â¯0.67, pâ¯=â¯.006) even after adjusting for mean levels of affect. Although greater negative affect variability is associated with worse sleep quality (bâ¯=â¯-0.77, pâ¯=â¯.02) and greater morning tiredness (bâ¯=â¯0.91, pâ¯=â¯.004), these associations are no longer significant once mean negative affect is added into the model. CONCLUSION: Findings support theory describing the downside in the variability of positive affect, and suggest that fluctuations in positive affect are related to poor sleep outcomes that have implications for overall health and well-being.
