From the COVID-19 lockdown to the new normal: Two-year changes in daily stress and positive event processes.

The emergence of the novel COVID-19 disease and the social distancing measures implemented to curb its spread affected most aspects of daily life. Past work suggests that during times of more severe stress, people respond to daily stressors with relatively higher negative affect. However, little is known about how people responded to daily stressors and positive events at different moments in time during the COVID-19 pandemic. Thus, we examined longitudinal changes in daily event-related affect (covariation of daily stressors or positive events with same-day affect) from Spring 2020 (wave 1) to 2022 (wave 2). The sample consisted of 324 adults aged 18-80 (mean = 52 years; 89% women) from the US and Canada who completed weeklong daily diaries at both waves. The results revealed improvements in affective well-being, stressor-related affect (i.e., smaller fluctuations in affect on stressor days vs. nonstressor days), and positive event-related affect (i.e., lower negative affect on days with vs. without positive events). Furthermore, as people gradually resumed their social activities from 2020 to 2022, people reported being exposed to an increased frequency of both stressors and positive events. This study highlights the potential influence of socio-historical phenomena, such as an ongoing pandemic, on the events that people encounter and how they emotionally respond to them.

Nightly Sleep Predicts Next-Morning Expectations for Stress and Positive Experiences.

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.

Positive event diversity: Relationship with personality and well-being.

OBJECTIVE: Examining the personality and well-being correlates of positive event diversity. BACKGROUND: Past research has highlighted that personality traits are linked to the frequency of daily positive events. This study is the first to examine positive event diversity, the extent to which positive events are spread across multiple types of positive life domains, as well as its personality and well-being correlates. METHOD: We conducted parallel analyses of three daily diary datasets (Ns = 1919, 744, and 1392) that included evening assessment of daily positive events and affective well-being. The Big Five personality traits were assessed in baseline surveys. RESULTS: Positive Event Diversity was related to higher person-mean daily positive affect but not negative affect. Higher Extraversion, Agreeableness, Openness, and lower Neuroticism were correlated with more positive event diversity. These associations became nonsignificant when controlling for positive event frequency. Positive event frequency moderated the link between positive event diversity and person-mean affect, such that higher positive event diversity was associated with higher negative and lower positive affect for people who experienced more frequent positive events. CONCLUSIONS: No consistent evidence was found for personality as a moderator of the positive event diversity-well-being link across the three studies. Further, the well-being implications of positive event diversity may be better understood when interpreting them alongside indexes of positive event frequency.

Everyday discrimination, daily affect, and physical symptoms during the COVID-19 pandemic.

OBJECTIVE: Abundant evidence has linked everyday discrimination with health risks. Because the COVID-19 pandemic has increased exposure to discrimination (e.g., based on age and race), it is important to understand the day-to-day implications of discrimination experiences for well-being. Furthermore, daily positive events were examined as a moderator due to their potential for mitigating the associations between everyday discrimination and well-being. METHOD: From March to August 2020, 1,212 participants aged 18-91 in the United States and Canada (84% women, 75% White) completed surveys for seven consecutive evenings about everyday discrimination, positive events, physical health symptoms, and positive and negative affect. Data were analyzed using multilevel models and controlled for sociodemographic factors. RESULTS: Everyday discrimination was reported on 9.3% of days when in-person or remote social interactions occurred. Within-persons, positive affect was lower and negative affect and physical symptoms were higher on days when discrimination occurred versus on days without discrimination. Positive events mitigated the within-person association between everyday discrimination and same-day negative affect, but not for positive affect or physical symptoms. Discrimination perceived to be due to age was associated with higher negative affect and lower positive affect within-persons. Positive events did not moderate the associations between age-based discrimination and same-day outcomes. CONCLUSIONS: Everyday discrimination was related to lower daily positive affect and higher negative affect and physical symptoms during the COVID-19 pandemic. This study provides initial evidence that daily positive events partially offset the increased negative affect associated with same-day discrimination.

Purposefulness and daily life in a pandemic: Predicting daily affect and physical symptoms during the first weeks of the COVID-19 response.

OBJECTIVE: Sense of purpose has been associated with greater health and well-being, even in daily contexts. However, it is unclear whether effects would hold in daily life during COVID-19, when people may have difficulty seeing a path towards their life goals. DESIGN: The current study investigated whether purposefulness predicted daily positive affect, negative affect, and physical symptoms. Participants (n = 831) reported on these variables during the first weeks of the COVID-19 response in North America. MAIN OUTCOME MEASURES: Participants completed daily surveys asking them for daily positive events, stressors, positive affect, negative affect, physical symptoms, and purposefulness. RESULTS: Purposefulness at between- and within-person levels predicted less negative affect and physical symptoms, but more positive affect at the daily level. Between-person purposefulness interacted with positive events when predicting negative and positive affect, suggesting that purposeful people may be less reactive to positive events. However, between-person purposefulness also interacted with daily stressors, insofar that stressors predicted greater declines in positive affect for purposeful people. CONCLUSION: Being a purposeful person holds positive implications for daily health and well-being, even during the pandemic context. However, purposefulness may hold some consequences unique to the COVID-19 context, which merit attention in future research.

Personality differences in the occurrence and affective correlates of daily positive events.

OBJECTIVE: Previous research shows that Neuroticism predicts exposure and affective reactivity to daily stressors. Zautra and colleagues extended this work to daily positive events. Building on these frameworks, we examined the Big Five personality traits as predictors of the occurrence and affective correlates of daily positive events. METHOD: Participants in two national U.S. daily diary studies (NSDE 2: N = 1,919 and NSDE Refresher: N = 778; aged 25-84) reported daily positive events, emotions specific to the events, and daily affect for 8 consecutive days. RESULTS: In parallel analyses in both samples, Extraversion and in the NSDE Refresher sample only Openness (but not Neuroticism, Conscientiousness, or Agreeableness) predicted more frequent positive event occurrence. All Big Five traits were associated with one or more emotional experiences (e.g., calm, proud) during positive events. Neuroticism predicted greater event-related positive affect in the NSDE 2 sample, whereas Agreeableness was related to more event-related negative affect in the NSDE Refresher sample. CONCLUSIONS: The Big Five personality traits each provided unique information for predicting positive events in daily life. The discussion centers on potential explanations and implications for advancing the understanding of individual differences that contribute to engagement in positive experiences.

Associations Between Intraindividual Variability in Sleep and Daily Positive Affect.

Recent research highlights a variety of negative outcomes associated with intraindividual variability in positive affect (PA) and in sleep. Thus, this study examined the associations of variability in multiple dimensions of sleep (quality, duration, wake after sleep onset, bedtime, rise-time) with mean and variability in PA. For 7 days, morning and evening surveys were collected online from two separate samples: community-based adults (N = 911) and university students (N = 322). Regression analyses revealed that across both samples, people with more variable sleep quality exhibited greater fluctuations in PA throughout the week and, surprisingly, higher levels of PA on average. In the community sample only, individuals with more variable sleep duration had lower and more variable PA. Findings suggest that fluctuations in sleep quality and duration are linked with daily PA outcomes, which is important to consider as technological advances and modern demands make inadequate and irregular sleep increasingly common.

Day-to-day associations between nightly sleep and next-day well-being amid the COVID-19 pandemic in North America.

OBJECTIVE: Sleep may be especially important for maintaining health and well-being in daily life amid the stress of the coronavirus disease 2019 (COVID-19) pandemic. This preregistered study examined the associations of sleep quality, duration, and efficiency with next-day physical symptoms, affect, and stressors during the COVID-19 pandemic in North America, in addition to evaluating individual differences in COVID-19 threat as a moderator. METHOD: From mid-March to early August 2020, 1025 adults from Canada and the United States aged 18-91 reported COVID-19 threat at baseline and subsequently completed twice-daily diaries for one week about their sleep, negative affect, stressors, and physical symptoms. RESULTS: Within-persons, nights with better-than-usual sleep quality predicted lower next-day negative affect, physical symptoms, and stressor occurrence. Better-than-usual sleep efficiency and longer-than-usual sleep duration also predicted lower next-day physical symptoms. COVID-19 threat ratings moderated several of these associations, such that individuals with higher COVID-19 threat showed weaker within-person associations of sleep duration and efficiency with next-day well-being, compared to individuals with lower-to-moderate levels of COVID-19 threat. For the reversed direction of association, stressor occurrence predicted shorter-than-usual sleep that night, but no other links between daily well-being and subsequent sleep were observed. DISCUSSION: Sleep quality, efficiency, and duration were important predictors of daily health and well-being during the COVID-19 pandemic, but the protective associations between sleep and next-day well-being were attenuated among people with higher COVID-19 threat. These findings highlight the role of heightened stress contexts when considering the benefits of sleep on daily health and well-being.

Psychological distress in North America during COVID-19: The role of pandemic-related stressors.

RATIONALE: The COVID-19 pandemic has wreaked havoc on lives around the globe. In addition to the primary threat of infection, widespread secondary stressors associated with the pandemic have included social isolation, financial insecurity, resource scarcity, and occupational difficulties. OBJECTIVE: The current study examined the impact of these disruptions on psychological distress during the initial adjustment phase to the pandemic in North America. METHOD: A sample of 2463 residents of the US and Canada completed both baseline and follow-up surveys across several weeks between March and May 2020. RESULTS: Those participants perceiving stress related to higher levels of personal threat to health and to the well-being of family members at baseline reported higher levels of depressive symptoms at follow-up, even after controlling for baseline depressive symptoms. In addition, pandemic-related secondary stressors (social isolation, financial insecurity, occupational difficulty, and resource scarcity) were all independently associated with depressive symptoms at follow-up, controlling for both baseline depression and perceived health threats. The results were robust and held up after controlling for demographic factors. Women, young adults, and those who reported lower income were all at higher risk for subsequent depressive symptoms. CONCLUSION: Findings from the present study can help to identify key groups at risk for mental health problems during the pandemic, and indicate actionable areas for targeted intervention.

Habit formation following routine-based versus time-based cue planning: A randomized controlled trial.

OBJECTIVES: Habit formation has been identified as one of the key determinants of behaviour change. To initiate habit formation, self-regulation interventions can support individuals to form a cue-behaviour plan and to repeatedly enact the plan in the same context. This randomized controlled trial aimed to model habit formation of an everyday nutrition behaviour and examined whether habit formation and plan enactment differ when individuals plan to enact their behaviour in response to a routine-based versus time-based cue. DESIGN: Following a baseline assessment, N = 192 adults (aged 18-77 years) were randomly assigned to a routine-based cue or a time-based cue planning intervention, in which they selected an everyday nutrition behaviour and linked it to a daily routine or a time cue. METHODS: Participants responded to daily questionnaires over 84 days assessing plan enactment and the behaviour's automaticity (as an indicator of habit formation). Multilevel models with days nested in participants were fitted. RESULTS: As indicated by asymptotic curves, it took a median of 59 days for participants who successfully formed habits to reach peak automaticity. Group-level analyses revealed that both routine-based and time-based cue planning led to increases in automaticity and plan enactment, but no between-condition differences were found. Repeated plan enactment was a key predictor for automaticity. CONCLUSIONS: Linking one's nutrition behaviour to a daily routine or a specific time was similarly effective for habit formation. Interventions should encourage persons to repeatedly carry out their planned behaviour in response to the planned cue to facilitate habit formation.

Helping Amid the Pandemic: Daily Affective and Social Implications of COVID-19-Related Prosocial Activities.

BACKGROUND AND OBJECTIVES: The novel coronavirus disease 2019 (COVID-19) pandemic may have prompted more engagement in prosocial activities, such as volunteering and support transactions. The day-to-day affective and social implications of these activities for adults of different ages are unknown. The current study examined associations of daily prosocial activities with affective and social well-being, and whether these associations varied by age. RESEARCH DESIGN AND METHODS: Participants ages 18-91 in Canada and the United States (N = 1,028) completed surveys for 7 consecutive evenings about their daily experiences of COVID-19-related prosocial activities (formal volunteering, support provision, support receipt), positive and negative affect, and satisfaction with social activities and relationships. Analyses were conducted using multilevel modeling and accounted for a range of potential confounding factors (e.g., sociodemographics, work, family, caregiving, daily stressors). RESULTS: Older age predicted more frequent formal volunteering, as well as more support provision and support receipt due to COVID-19. In particular, middle-aged and older adults provided more emotional support than younger adults, middle-aged adults provided the most tangible support, and older adults received the most emotional support. All three types of prosocial activities were associated with higher positive affect and greater social satisfaction on days when they occurred. Providing COVID-19-related support further predicted lower same-day negative affect. Age did not significantly moderate these associations. DISCUSSION AND IMPLICATIONS: Older age was related to more frequent engagement in prosocial activities during the COVID-19 crisis. These activities were associated with improved daily affective and social well-being for adults of all ages.

The Ups and Downs of Daily Life During COVID-19: Age Differences in Affect, Stress, and Positive Events.

OBJECTIVES: Past research has linked older age with greater emotional well-being and decreased reactivity to stressors, but it is unknown whether age-related advantages in emotional well-being are maintained in the wake of COVID-19. We examined age differences in exposure and affective reactivity to daily stressors and positive events in the first several weeks of the COVID-19 outbreak. METHODS: In March and April 2020, 776 adults from Canada and the United States aged 18-91 (mean age 45) years reported COVID-19 threats at baseline, then completed nightly surveys for 1 week about their daily stressors, positive events, and affect. RESULTS: Younger age predicted more concerns about the threat of COVID-19 across multiple domains, in addition to lower positive affect, higher negative affect, and less frequent positive events. Younger adults had more non-COVID-19 daily stressors and higher perceived control over stressors, but lower perceived coping efficacy than older adults. There were no age differences in the frequency of COVID-19 daily stressors nor perceived stressor severity. Younger adults had greater reductions in negative affect on days when more positive events occurred and greater increases in negative affect on days when non-COVID-19 stressors occurred. Age moderation was attenuated for negative affective reactivity to COVID-19 stressors. Age did not moderate positive affective reactivity to daily events. DISCUSSION: In the early weeks of the pandemic, older adults showed better emotional well-being and less reactivity to stressors but did not differ from younger adults in their exposure to COVID-19 stressors. Additionally, younger adults benefited more from positive events.

Sleep duration and affective reactivity to stressors and positive events in daily life.

OBJECTIVE: Experimental evidence suggests that inadequate sleep disrupts next-day affective processing and evokes greater stress reactivity. However, less research has focused on whether sleep predicts next-day affective reactivity to naturally occurring stressors and positive events in daily life, as well as the reversed direction of association (i.e., affective reactivity to daily events as predictors of subsequent sleep). The purpose of this study was to evaluate the within-person, bidirectional associations between nightly sleep duration and day-to-day fluctuations in affect related to stressors and positive events. METHOD: Adults ages 33-84 (N = 1,982, 57% female) in the U.S. National Study of Daily Experiences II reported sociodemographics and chronic conditions at baseline, then completed telephone interviews for 8 consecutive days about their sleep duration, daily stressors, positive events, and affect. RESULTS: Prior-night sleep duration moderated the link between current-day events and positive affect, but not negative affect. Specifically, nights of shorter-than-usual sleep duration predicted more pronounced decreases in positive affect in response to daily stressors, as well as smaller increases in positive affect in response to daily positive events. Results for the reversed direction of association showed no evidence for affective reactivity to daily events as predictors of subsequent sleep duration. People with more chronic conditions were more reactive to positive events, particularly after nights of longer sleep. CONCLUSION: Affective reactivity to daily stressors and positive events vary based upon sleep duration, such that sleep loss may amplify loss of positive affect on days with stressors, as well as reduce positive affective responsiveness to positive events.

Long-Term Health Implications of Students' Friendship Formation during the Transition to University.

BACKGROUND: The transition to university is a major life change wherein young adults' primary support system shifts from the family to peers. Can change in social integration (operationalised as number of friends) during the first term at university contribute to students' health years later, and if so, how? METHODS: The friendship formation of 67 students at a large Canadian university was assessed during their first term. These data were used to predict self-reported health and health behaviors (physical exercise, diet, tobacco, alcohol and marijuana consumption) at a follow-up assessment that occurred near the end of their time at university (2 or 3 years later). RESULTS: Linear regression models showed that students who made more friends in their first term reported better health and a healthier diet at the follow-up (2 or 3 years later). Perceived social support at the follow-up mediated the relationship between friendship formation and self-reported health but not diet. CONCLUSIONS: This study provides evidence for both (1) an indirect effect of friendship formation on self-reported health via perceived social support, and (2) a direct effect of friendship formation on a healthy diet. Broadly, these results highlight the importance of friendship formation and social integration for the long-term well-being of university students.

Petting away pre-exam stress: The effect of therapy dog sessions on student well-being.

Recently, many universities have implemented programmes in which therapy dogs and their handlers visit college campuses. Despite the immense popularity of therapy dog sessions, few randomized studies have empirically tested the efficacy of such programmes. The present study evaluates the efficacy of such a therapy dog programme in improving the well-being of university students. This research incorporates two components: (a) a pre/post within-subjects design, in which 246 participants completed a brief questionnaire immediately before and after a therapy dog session and (b) an experimental design with a delayed-treatment control group, in which all participants completed baseline measures and follow-up measures approximately 10 hr later. Only participants in the experimental condition experienced the therapy dog session in between the baseline and follow-up measures. Analyses of pre/post data revealed that the therapy dog sessions had strong immediate benefits, significantly reducing stress and increasing happiness and energy levels. In addition, participants in the experimental group reported a greater improvement in negative affect, perceived social support, and perceived stress compared with those in the delayed-treatment control group. Our results suggest that single, drop-in, therapy dog sessions have large and immediate effects on students' well-being, but also that the effects after several hours are small.
