Sleep difficulties in college students: The role of stress, affect and cognitive processes

The role of arts therapies in mitigating Sleep Initiation and Maintenance Disorders: a systematic review

Introduction

Arts therapies offer effective non-pharmacological intervention for Sleep Initiation and Maintenance Disorders (SIMDs), encompassing both passive and active modalities. This review assesses their effectiveness and ethical considerations, focusing on music therapy, meditation, and Tai Chi.

Methods

Following PRISMA guidelines, a detailed search across PubMed, the Cochrane Library, Web of Science, and CNKI identified 17 relevant RCTs. Utilizing the Joanna Briggs Institute (JBI) quality criteria and the PICO(S) framework for data extraction ensured methodological integrity.

Results

Analysis shows arts therapies significantly improve sleep quality. Music therapy and meditation yield immediate benefits, while Tai Chi and Qigong require longer commitment for significant outcomes.

Discussion

The link between SIMDs and mental health issues like anxiety, stress, and depression suggests arts therapies not only enhance sleep quality but also address underlying mental health conditions. The evidence supports a wider adoption of arts therapies in treating SIMDs due to their dual benefits.

Investigating the linkages between food insecurity, psychological distress, and poor sleep outcomes among U.S. college students

OBJECTIVE

Research overwhelmingly demonstrates that sleep is key to human health and wellbeing. Several factors likely contribute to sleep quality, including factors, such as food security and low income. In addition, exposure to structural inequalities early in life likely have downstream effects upon multiple dimensions of health. The objective of this study is to fill gaps in literature by specifically examining the associations between childhood food insecurity, current food insecurity, psychological distress, and sleep among college students.

METHODS

QR codes were randomly distributed to students, linking them to an online quantitative survey. The survey measured sociodemographic variables, food security (current and childhood), diet, mental distress, and sleep quality. A total of n = 134 completed the entire survey. Data were analyzed using binary and multiple linear regressions, as well as cross-tabulations.

RESULTS

The findings revealed that psychological distress was the primary factor influencing sleep health (𝛽 = 1.51, p < .01). Students reporting higher childhood food insecurity were more likely to experience extreme psychological distress (OR = 4.61), food insecurity in college (OR = 8.41), and lack of stable housing (OR = 5.86).

CONCLUSION

This study demonstrates that potential linkages exist between childhood food insecurity, poor sleep, and greater psychological distress. While acknowledging the contribution of other factors, the study highlights the importance of addressing food insecurity in relation to sleep health, considering the significant impact of sleep to overall health and wellbeing.

The Indirect Effect of Sleep Quality on Stress-Related Psychosocial Outcomes in Adolescents: An Investigation Across Genders

Sleep is foundational for adolescent psychosocial outcomes though often compromised by normative developmental changes and external factors. This cross-sectional study examined sleep quality as a mechanism linking stress and psychosocial outcomes and explored gender differences. Adolescents (N = 246; Mage=15.8; 46.3% female) completed self-report measures assessing sleep quality and psychosocial outcomes. Structural equation modeling results indicated sleep quality accounted for 78.4% of the total effect of stress on school functioning (b=-0.45, p < 0.001) and 54.2% of the total effect of stress on pain (b = 0.14, p = 0.002). A larger indirect effect of sleep quality on school functioning (b=-0.26, p = 0.016) emerged for boys than girls, and the effect of sleep quality on pain was significant only for girls (b = 0.18, p < 0.001, 69.6% of total effect). Sleep quality explained a large proportion of the effect of stress on school functioning and pain. Sleep quality represents a modifiable transdiagnostic pathway that may buffer the effects of stress in adolescence.

A Mixed-Methods, Multimedia Pilot Study to Investigate Sleep Irregularity Determinants Among Undergraduate Students

PURPOSE

To pilot a novel approach investigating the interplay of social and institutional determinants influencing university undergraduate student sleep patterns.

DESIGN

A two-part, three-phase mixed-methods approach.

SETTING

A mid-size US university conducted in spring and fall 2020.

PARTICIPANTS

191 undergraduate students (69 first-years, 43 second-years, 48 third-years, 31 fourth-years).

METHOD

For Part A, participants texted their activities and emotions in real time, producing a data-rich, weeklong diary of comprehensive activity logs, emoticons, multimedia submissions, and juxtapositions of ideal vs real schedules. Semi-structured contextual interviews were also conducted. For Part B, a one-time survey examined Part A insights across all class years. These diverse datasets were triangulated using thematic, comparative, and content analyses through MAXQDA software and visual mapping methods.

RESULTS

Three preliminary themes were identified as encouraging an irregular sleep schedule: a prevailing academic ethos emphasizing busyness, time management challenges, and the rhythm of institutional schedules and deadlines. An overarching theme suggests that perceptions of peer sleep habits and academic prioritization above all else could be influential across factors.

CONCLUSION

This pilot study indicates that sleep regularity among undergraduates is potentially shaped by individual choices combined with broader institutional paradigms. While it is limited by its exploratory nature, timing, and small sample size, the results highlight the promise of this methodology for more extensive studies and suggest that future interventions should emphasize systemic changes that prioritize sleep.

Sleep quality and associated factors among university students in Africa: a systematic review and meta-analysis study

Background

Poor sleep quality significantly impacts academic performance in university students. However, inconsistent and inconclusive results were found in a study on sleep among university students in several African nations. Therefore, this study aimed to estimate the pooled prevalence and associated factors of poor sleep quality among university students in Africa.

Methods

The databases PubMed, Scopus, Cochrane Library, Science Direct, African Journal Online, and Google Scholar were searched to identify articles. A total of 35 primary articles from 11 African countries were assessed and included in this systematic review and meta-analysis. Data were extracted by using a Microsoft Excel spreadsheet and exported to STATA version 14 for analysis. The I2 test was used to assess the statistical heterogeneity. A random effect meta-analysis model was employed with 95% confidence intervals. Funnel plots analysis and Egger regression tests were used to check the presence of publication bias. A subgroup analysis and a sensitivity analysis were done.

Results

A total of 16,275 study participants from 35 studies were included in this meta-analysis and systematic review. The overall pooled prevalence of poor sleep quality among university students in Africa was 63.31% (95% CI: 56.91-65.71) I2 = 97.2. The subgroup analysis shows that the combined prevalence of poor sleep quality in East, North, West, and South Africa were 61.31 (95% CI: 56.91-65.71), 62.23 (95% CI: 54.07-70.39), 54.43 (95% CI: 47.39-61.48), and 69.59 (95% CI: 50.39-88.80) respectively. Being stressed (AOR= 2.39; 95% CI: 1.63 to 3.51), second academic year (AOR= 3.10; 95% CI: 2.30 to 4.19), use of the electronic device at bedtime (AOR= 3.97 95% CI: 2.38 to 6.61)) and having a comorbid chronic illness (AOR = 2.71; 95% CI: 1.08, 6.82) were factors significantly associated with poor sleep quality.

Conclusion

This study shows that there is a high prevalence of poor sleep quality among university students in Africa. Being stressed, in the second year, using electronic devices at bedtime, and having chronic illness were factors associated with poor sleep quality. Therefore, addressing contributing factors and implementing routine screenings are essential to reduce the burden of poor sleep quality.

The effect of anxiety on sleep disorders in medical students: a moderated mediation model

The relationship between anxiety and sleep disorders is a key research topic in the academic community. However, evidence on the mechanism through which anxiety influences sleep disorders remains limited. The purpose of this study was to investigate the roles of flourishing and neuroticism in the mechanism through which anxiety influences sleep disorders in medical students. We constructed a moderated mediation model and tested the mediating role of flourishing and the moderating role of neuroticism in medical college students. The results showed that: (1) anxiety was significantly and positively related to sleep disorders and significantly and negatively related to flourishing; flourishing was significantly and negatively related to sleep disorders; neuroticism was significantly and positively related to sleep disorders; (2) flourishing had a mediation effect on the relationship between anxiety and sleep disorders; (3) neuroticism moderated the process through which flourishing mediated the effect of anxiety on sleep disorders. Our research expands the literature on the mechanism underlying the effects of anxiety on sleep disorders and provides insights into the potential prevention and intervention of sleep and emotional problems in medical students.

Self-control fluctuates from day to day and is linked to subjective well-being within and between persons

The psychological trait of self-control has been linked to interindividual differences in subjective well-being: Individuals with higher self-control report less negative affect, more positive affect, and higher life satisfaction. However, less is known about how much self-control fluctuates from day to day and how these fluctuations are related to subjective well-being. This intensive longitudinal study describes day-to-day fluctuations in self-control and investigates whether and how they are related to subjective well-being. A sample of 64 undergraduate students at the entry phase of university (M = 22.55 years, SD = 6.51, range = 18-53, 97% female) provided 1459 reports of their self-control and subjective well-being, collected every evening across three 9-day measurement bursts over 6 months. Participants' self-control fluctuated substantially from day to day with less than 40% of the variability in daily self-control being attributable to interindividual differences in self-control. On days with higher self-control, participants reported less negative affect, more serenity, and higher life satisfaction. We found no relationship between self-control and vigor. The findings suggest that researchers need to go beyond current assessment practices and theories treating self-control as a stable trait to help develop tailored well-being interventions for everyday life.

Effect of physical activity on sleep problems in sedentary adults: a scoping systematic review

This systematic review was steered forward with the aim of analyzing how different forms of exercise could influence the objective and subjective sleep outcome among sedentary adults with sleep problems. A pre-detailed study protocol (PROSPERO ID: CRD42021229649) was used to search for RCTs through five databases. The methodological quality of the included RCTs was assessed by PEDro and studies were included if they scored > 5. Effect size of all outcome measures were calculated using Cohen's d. Of the 4154 studies, 19 studies met the inclusion criteria and underwent quality assessment using 11-point PEDRO scale. 9 studies with PEDro score > 5 were finally included in this systematic review out of which, participants of 4 studies had insomnia (nrange = 37-48, agerange = 44-60 years), 3 studies had poor sleep quality (nrange = 80-275, agerange = 52-70 years) and 2 studies had obstructive sleep apnea syndrome (nrange = 26-68, agerange = 51 years). Majority of studies revealed that physical activity seems to have greater improvement with a large effect size on subjective sleep outcomes among sedentary adults with sleep problems like insomnia, poor sleep quality and OSAS, whereas limited studies and non-significant results were observed on objective sleep outcomes. Physical activity improves sleep outcomes especially among sedentary middle-aged and older adults. More research is needed to examine the effect of physical activity programs on objective sleep outcomes especially in younger sedentary adults with different sleep problems.

Tailored internet-delivered cognitive behavioral therapy for individuals experiencing psychological distress associated with climate change: A pilot randomized controlled trial

Even among people who are not directly impacted by the consequences of climate change, perceptions about the ongoing crisis can have a negative effect on mental health and well-being. However, empirical evidence on interventions aiming to provide support is currently scarce. In order to address this issue, a pilot-RCT was carried out to investigate the effects of a novel ICBT treatment program. Sixty participants (23-73 years) were recruited and randomly allocated to eight weeks of therapist-supported ICBT (n = 30) or a wait-list control condition (n = 30). Measures of depressive symptoms, stress, and quality of life were used as primary outcomes, while measures of anxiety, insomnia, climate change-related distress, pro-environmental behaviour, and alcohol use were used as secondary outcomes. The treatment group had moderate to large between-group effects compared to the waitlist group on measures of depression (d = 0.87), stress (d = 0.76), quality of life (d = 0.79) and climate change-related distress (d = 0.79). There were no significant between-group differences on the other outcome measures. The results from this pilot-RCT indicate that individually tailored ICBT can be an effective way to reduce psychological distress associated with climate change without reducing pro-environmental behaviour.

An assessment of environmental literacy, behaviors, attitudes and lifestyle factors of college students

OBJECTIVE

Evaluate associations between environmental literacy, attitudes, sustainability behaviors, health, and lifestyle factors among undergraduates.

PARTICIPANTS

Convenience sample of 345 students at a mid-sized, rural university completed the survey fall 2019.

METHODS

Descriptive statistics, correlations, and exploratory factor analysis were used to evaluate data.

RESULTS

Overall, though participants exhibited a lack of environmental knowledge (average score five of ten), they possessed pro-health and pro-environment attitudes and were likely to engage in corresponding behaviors (e.g. recycling, waste reduction, etc.). Principal axis factor analysis identified five underlying factors: liberal/progressive views, individual eco-friendly practices, personal health, healthy lifestyle, and waste reduction.

CONCLUSION

Correlational analyses indicated students who value health and engage in healthier behaviors also value the environment. While most agreed environmental sustainability is important, recycling behaviors and sustainability knowledge were mediocre. Understanding underlying factors such as environmental attitudes and sustainability-related behaviors can drive intervention strategies to move students to action.

Associations between insomnia symptom trajectories with depression and self-harm behaviors in Chinese college students before and during the COVID-19 pandemic: A five-wave longitudinal investigation

BACKGROUND

Sleep problems are highly prevalent during COVID-19 pandemic. However, only very limited studies have examined the changing patterns of insomnia symptom before and during the COVID-19 pandemic, and most of these studies were limited to two-wave designs and the variable-centered approach.

METHODS

The data was taken from a large-scale health-related cohort among Chinese college students. This cohort was a five-wave design and 3834 participants who completed at least two waves were included in the present study. Growth mixture modeling (GMM) was used to estimate trajectory classes for insomnia symptoms, followed by binary logistic regression to explore the association between trajectory classes and subsequent mental health problems.

RESULTS

GMM analyses extracted four distinct trajectories of insomnia symptoms: stable-low pattern (n = 2897, 75.6 %), increasing pattern (n = 405, 10.6 %), decreasing pattern (n = 182, 4.7 %), and stable-high pattern (n = 350, 9.1 %). Additionally, we found that individuals in stable-high and increasing patterns were more likely to experience mental health problems after the COVID-19 pandemic even after adjusting significant covariates and outcomes at baseline.

CONCLUSIONS

Appreciable heterogeneity in insomnia symptoms among college students was revealed before and during the COVID-19 pandemic. About 20 % of college students were classified as high-risk patterns of insomnia symptoms. Psychological interventions should target such vulnerable groups to reduce the rates of mental health problems.

A randomized controlled trial of mindfulness: effects on university students' mental health

BACKGROUND

The development of mental health disorders is common in the university population, and mindfulness-based interventions (MBIs) seem to be effective in addressing them in different contexts. Thus, this study investigated the impact of an 8-week MBI adapted to university students from the Mindfulness-Based Relapse Prevention (MBSR) on different symptoms related to mental health problems, specifically symptoms of anxiety, depression, stress and insomnia.

METHODS

University students (n = 136) were randomized into MBI group (n = 71) or wait-list group (n = 65). All participants completed self-administered questionnaires before and after the intervention, and the experimental group answered questionnaires weekly during intervention. Generalized mixed models were used to assess the effects of the intervention.

RESULTS

There were improvements in the symptoms of stress (B = 5.76, p < 0.001), depression (B = 1.55, p < 0.01) and insomnia (B = 1.35, p = 0.020) from the beginning of the intervention to the final assessment when it was compared to the control group. No effect was found in respect of trait anxiety. The MBI was found to be effective in reducing important symptoms related to university students' mental health, possibly grounding further research on the intervention's potential of preventing the development of mental disorders.

TRIAL REGISTRATION

The research was registered in the Brazilian Registry of Clinical Trials (ReBEC) - number RBR-63qsqx, approved at 09/16/2019.

The associations between academic stress and depression among college students: A moderated chain mediation model of negative affect, sleep quality, and social support

BACKGROUND

Growing competition in tight job market and academic excellence as a social norm in Asian culture have made Chinese college students burdened with immense academic stress.

OBJECTIVES

This study aimed to explore the associations between academic stress and depression, and the mediating roles of negative affect and sleep quality, as well as the moderating role of social support in the relationship between negative affect and sleep quality.

METHODOLOGY

A convenience sample of 221 male and 479 female college students aged between 17 and 25 completed questionnaires on academic stress, depression, negative affect, sleep quality and social support.

RESULTS

Results indicated that academic stress could not only directly affect depression (b = 0.31, p < 001), but also affect depression through the mediation role of negative affect and sleep quality. The chain mediating effects includes three paths, namely, the mediating role of negative affect (indirect effect = 0.21, percentage of total effect = 69.58 %), the mediating role of sleep quality (indirect effect = 0.06, percentage of total effect = 21.03 %), and the chain mediating role of negative affect and sleep quality (indirect effect = 0.06, percentage of total effect = 19.86 %). Social support moderated the adverse influence of negative affect on sleep quality. Social support decreases the impact of negative affect on sleep quality. Specifically, the association between negative affect and sleep quality was stronger for college students with low (bsimple = 0.44, p < 0.001) social support than those with high (bsimple = 0.32, p < 0.001) social support.

IMPLICATIONS

The results advanced our understanding of how academic stress affects college students' depression. These findings provide implications on the cultivation of stress coping strategies, promotion of emotion regulation skills, exaltation of sleep quality, and improvement of the social support level aiming for future depression preventions and interventions. Specific measures include setting up psychological health courses, teaching emotion management strategies, and establishing web-based programme steming from acceptance and commitment therapy. It should be noted that the cross-sectional design means the causal associations among the variables could not be determined.

Perceived stress, mental health symptoms, and deleterious behaviors during the transition to college

BACKGROUND

This study examined associations between different sources of chronic perceived stress and deleterious behaviors (eating disorder symptoms, insufficient sleep, and insufficient vigorous physical activity) among first-year college students.

METHODS

The study used data on 885 first-year students (ages 18-20) at a large public university in North Carolina. The prevalence of deleterious behaviors was evaluated. Associations were estimated between different sources of chronic perceived stress (academic, future, peers, friendships, romantic, appearance, health, chronic illness, financial, work, family) and health behaviors after controlling for psychosocial supports and demographics. Moderating effects of gender and moderate-severe anxiety/depression symptoms were also tested.

RESULTS

19% of first-year student reported symptoms of eating disorders, 42% insufficient sleep, and 43% insufficient vigorous physical activity. Perceived chronic stress increased the odds of reporting these deleterious behaviors. These effects were not moderated by gender or moderate-severe anxiety/depression symptoms. Appearance- and health-related stress were associated with eating disorder symptoms; health- and romantic-related stress were associated with insufficient sleep; and health-related stress was associated with insufficient vigorous physical activity.

LIMITATIONS

Outcomes were survey-based. The study was based on cross-sectional data from a single university, so the direction of causality cannot be determined, and more work needs to be done to determine whether this would extend to other populations.

A clinical and technical methodological review on stress detection and sleep quality prediction in an academic environment

BACKGROUND

Mental health in recent times is a much talked about topic and its effects on the sleep health of the students are said to result in long-term health issues if not identified and resolved. Students who are subjected to psychological stress have often been reported to have lower sleep quality which together has affected the academic performance of the students.

OBJECTIVE

While stress has its adverse effect on students'quality of sleep, an effort is also made to identify standard techniques and tools to automatically assess stress levels and sleep quality in a non-invasive environment among students only. This article mainly focuses on the Clinical and technical methodology employed in stress level detection and sleep quality prediction among students.

METHODS

This study was conducted by examining all research studies conducted in the past with respect to students in an academic setting from year 2000 to early 2022. The papers under study where finalised based on different methodologies involved in stress level detection and sleep quality prediction considering both in unimodal and multimodal measurements.

RESULTS

While questionnaires and physiological signals are used as a standard measuring tool, it is mostly used in a unimodal environment to measure students' mental stress or sleep quality in academic settings.

CONCLUSION

This paper describes in detail the clinical aspect of the association between mental stress, sleep quality, and academic performance in students followed by technical aspects to analyse the stress levels and sleep quality both qualitatively and quantitatively in an academic environment.

Differential Associations of Cognitive Emotion Regulation Strategies with Depression, Anxiety, and Insomnia in Adolescence and Early Adulthood

While difficulties with emotion regulation (ER) are consistently linked to poor mental health in adulthood, findings in adolescence have been more mixed. Cognitive ER strategies, which involve the ability to manage emotions through mental processes, may be particularly important during different stages of development due to age-specific adjustments. We conducted two exploratory and cross-sectional studies to examine the relationships between cognitive ER strategies and mental health (i.e., depressive, anxiety, and insomnia symptoms) in two samples: 431 young adults (M_age = 20.66 ± 2.21; 70% women and 30% men) and 271 adolescents (M_age = 14.80 ± 0.0.59; 44.6% girls and 55.4% boys). The participants completed a group of questionnaires, including the Cognitive Emotion Regulation Questionnaire, the Insomnia Severity Index, the Beck Depression Inventory-II, the State-Trait Anxiety Inventory, and the Youth Self Report. We employed hierarchical multiple regressions to assess the unique contribution of cognitive ER strategies to mental health outcomes. Maladaptive strategies (such as rumination and catastrophizing) were consistently associated with impaired mental health in both samples, while adaptive strategies (such as positive refocusing and positive reappraisal) were only associated with better mental health in young adults. These findings support the importance of cognitive ER strategies as potential risk factors for psychopathology and suggest that interventions aimed at improving emotion regulation may be beneficial. The age-specific differences in the relationship between cognitive ER strategies and mental health may reflect the refinement of emotion regulation abilities across the lifespan.

COVID-19 anxiety and mental health among university students during the early phases of the U.S. pandemic

OBJECTIVE

This study examined the impact of COVID-19 in the early stages of the pandemic on university students in the U.S. by: (1) characterizing COVID-19-related disruptions; (2) evaluating health anxiety, obsessive-compulsive (OC), depression, and stress symptoms; and (3) analyzing the unique role of COVID-19 anxiety on mental health outcomes, after accounting for relevant variables.

PARTICIPANTS

Participants included 263 students (63.9% female).

METHODS

Data were collected online between March 19, 2020 and May 1, 2020.

RESULTS

Participants screened positive for health anxiety (6.5%), OC symptoms (48.7%), or depression (29.7%). COVID-19 anxiety was positively associated with mental health symptoms. After controlling for demographics and COVID-19 impact, COVID-19 anxiety accounted for significant variance in health anxiety, OC symptoms, and stress.

CONCLUSIONS

Findings demonstrate the vast impact of COVID-19 on mental health among university students and provide guidance for identifying mental health priorities in the context of public health crises.

Assessing the Impact of Technology Use, Social Engagement, Emotional Regulation, and Sleep Quality Among Undergraduate Students in Jordan: Examining the Mediating Effect of Perceived and Academic Stress

The quality of sleep is affected by several psychological factors. University students experience different types of stress and develop various strategies to cope with it. This study assesses the impact of technology use, social engagement, emotional regulation, and sleep quality among undergraduate students in Jordan, while examining the mediating effect of perceived and academic stress. A convenience sample of 308 undergraduate students was selected from the University of Jordan. The results indicated that the study model was fit, with significant direct negative impacts of social engagement, time management, and emotional regulation on perceived stress. Additionally, there was a significant direct negative relationship between technology use, time management, and emotional regulation on academic stress. The results show indirect significant standardized effects of social engagement, time management, and emotional regulation on the quality of sleep through the mediation of perceived stress.

The relationship between childhood trauma and insomnia among college students with major depressive disorder: Mediation by the role of negative life events and dysfunctional attitudes

BACKGROUND

Insomnia is a common problem among patients with major depressive disorder (MDD). According to previous studies, the development and severity of Insomnia are influenced by childhood trauma experience. Furthermore, negative life events and dysfunctional attitudes may also mediate the impact. So, this study aimed to examine the association between childhood trauma, negative life events, dysfunctional attitudes and insomnia and investigate how negative life events and dysfunctional attitudes mediate the relationship between childhood trauma and insomnia in MDD.

METHOD

This cross-sectional study recruited 621 college students with MDD. The Childhood Trauma Questionnaire (CTQ), Life Event Scale (LES), Dysfunctional Attitude Scale (DAS), Insomnia Severity Index (ISI), and Hamilton Depression Scale-17 (HAMD-17) were used to assess participants' psychosocial factors. Descriptive analysis, Chi-square test, t-test, Pearson correlations, and serial mediation analyses were used in data analysis. In order to eliminate the influence of the severity of depression symptoms, severity of depression symptoms was used as a control variable in this study.

RESULTS

There were 166 (26.7%) participants having clinical insomnia (ISI score > 14). After controlling for the effect of severity of depression symptoms, results of serial mediation analyses determined that childhood trauma has a direct (Estimate = 0.109, 95%CI: 0.023,0.190) and indirect (Estimate = 0.090, 95%CI: 0.054,0.137) impact to insomnia. The indirect impact of childhood trauma on insomnia through the pathways of negative life events alone (Estimate = 0.050, 95%CI: 0.024,0.093), dysfunctional attitudes alone (Estimate = 0.027, 95%CI: 0.008,0.050), and negative life events to dysfunctional attitudes (Estimate = 0.013, 95%CI: 0.006,0.024) were significant.

CONCLUSIONS

This study demonstrates that screening for childhood trauma should be considered when treating insomnia in college students with MDD. Managing negative life events and dysfunctional attitudes may mitigate the negative impact of childhood trauma on insomnia in college students with MDD.

Association Between the Fatigue and Sleep Quality of Kidney Transplant Recipients: The Mediating Role of Rumination

ABSTRACT

Sleep disorders persist in renal transplant patients. Previous studies have showed that fatigue and rumination are an important determinant of sleep quality. However, very few studies have explored the mediating role of rumination in the relationship between fatigue and sleep quality in kidney transplant recipients. A descriptive cross-sectional research design was implemented, and 192 kidney transplant patients completed the short questionnaire about their recent experiences of fatigue, rumination, and sleep quality. The prevalence of sleep disorders among kidney transplant recipients was 19.3%. With rumination as a partial mediator, fatigue indirectly affected the patients' sleep quality. This indirect effect was 0.10 (95% confidence interval, 0.154-0.419). Our results indicate that the incidence of sleep disorders after renal transplantation was high, and the more tired kidney transplant recipients become, the more likely they are to ruminate, which leads to a decline in sleep quality.

Factors associated with perceived stress in Middle Eastern university students

Objective: University students face high levels of stress-related factors, such as an unfamiliar environment, challenging workload, and uncertainty about their ability to succeed. Participants: A total of 370 students in Qatar who consented to participate between February 2017 and February 2018. Methods: This cross-sectional study assessed perceived stress [using a validated 4-point perceived stress scale (PSS-4)], as well as diet, exercise, body mass index, sleep, and life satisfaction. Results: Among students aged 18-39 (mean = 20.1 ± 3.0 years), PSS-4 scores varied between 0 and 16 (mean = 7.4 ± 3.4). Elevated stress was significantly associated with female sex, country of origin, residing off-campus, eating when bored, lack of self-discipline, disturbed sleep, and low levels of life satisfaction. Furthermore, students with PSS-4 scores above the median level were 2.3 times likelier to report difficulty concentrating on academic work. Conclusion: Elevated stress levels are present in university students in Qatar. Strengthening coping skills may improve health and academic performance.

The association between race- and ethnicity-related stressors and sleep: the role of rumination and anxiety sensitivity

STUDY OBJECTIVES

This study was designed to investigate the association between psychosocial factors and self-reported sleep duration and two indices of sleep quality in a racially and ethnically diverse sample of adults. We investigated the relations between both rumination and anxiety sensitivity with these self-reported sleep outcomes. We also examined rumination and anxiety sensitivity as moderators of three race- and ethnicity-related stressors: discrimination, acculturative stress, and socioeconomic status.

METHODS

In a cross-sectional design, we assessed 1326 adults (ages 18-48 years) selected for self-reported racial and ethnic minority status. Regression analyses were used to examine the associations between demographic, social/environmental stressors, depression severity, rumination, and anxiety sensitivity and three sleep outcomes: sleep duration, sleep quality subscale, and global sleep quality.

RESULTS

Our findings supported the hypothesized role of rumination as an amplification factor for the influence of race- and ethnicity-related stressors on sleep duration and quality. Rumination was associated with all three sleep outcomes (sleep duration, sleep quality subscale, and global sleep quality) and was a moderator of the associations between discrimination and all 3 sleep outcomes. Anxiety sensitivity was not consistently associated with these sleep outcomes. Depression symptoms did not account for these findings.

CONCLUSIONS

If confirmed in longitudinal study, our findings introduce a potentially important treatment target-rumination-for addressing sleep disparities in prevention or intervention models. Rumination appears to amplify the negative sleep consequences of race- and ethnicity-related stressors and is a modifiable treatment target.

Sleep and affect: A conceptual review

Everyday experience suggests that sleep and affect are closely linked, with daytime affect influencing how we sleep, and sleep influencing subsequent affect. Yet empirical evidence for this bidirectional relationship between sleep and affect in non-clinical adult samples remains mixed, which may be due to heterogeneity in both construct definitions and measurement. This conceptual review proposes a granular framework that deconstructs sleep and affect findings according to three subordinate dimensions, namely domains (which are distinct for sleep and affect), methods (i.e., self-report vs. behavioral/physiological measures), and timescale (i.e., shorter vs. longer). We illustrate the value of our granular framework through a systematic review of empirical studies published in PubMed (N = 80 articles). We found that in some cases, particularly for sleep disturbances and sleep duration, our framework identified robust evidence for associations with affect that are separable by domain, method, and timescale. However, in most other cases, evidence was either inconclusive or too sparse, resulting in no clear patterns. Our review did not find support for granular bidirectionality between sleep and affect. We suggest a roadmap for future studies based on gaps identified by our review and discuss advantages and disadvantages of our granular dimensional framework.

Impact of Online Learning in the Context of COVID-19 on Undergraduates with Disabilities and Mental Health Concerns

The COVID-19 pandemic upended college education and the experiences of students due to the rapid and uneven shift to online learning. This study examined the experiences of students with disabilities with online learning, with a consideration of surrounding stressors such as financial pressures. In a mixed method approach, we compared 28 undergraduate students with disabilities (including mental health concerns) to their peers during 2020, to assess differences and similarities in their educational concerns, stress levels and COVID-19 related adversities. We found that students with disabilities entered the Spring quarter of 2020 with significantly higher concerns about classes going online, and reported more recent negative life events than other students. These differences between the two groups diminished three months later with the exception of recent negative life events. For a fuller understanding of students’ experiences, we conducted qualitative analysis of open ended interviews. We examined both positive and negative experiences with online learning among students with disabilities and mental health concerns. We describe how online learning enabled greater access–e.g., reducing the need for travel to campus–alongside ways in which online learning impeded academic engagement–e.g., reducing interpersonal interaction. We highlight a need for learning systems to meet the diverse and dynamic needs of students with disabilities.

Sleep Quality and Sleep Behaviors in Varsity Athletes: A Pilot Study

Sleep hygiene practices may hinder university athletes from obtaining quality sleep to support health and performance. We sought to provide a comprehensive evaluation of sleep quality and behaviors in varsity athletes using validated sleep questionnaires: the Athlete Sleep Screening Questionnaire (ASSQ) and the Athlete Sleep Behavior Questionnaire (ASBQ). Sixty-four (n = 64) athletes participated (54% female; 71% Caucasian). The mean age was 20.3 ± 1.7 years and the mean BMI was 23.3 ± 3.3. Fifty-one percent met the threshold for adequate sleep (7+ h) and 54% reported being somewhat/very satisfied with sleep quality. Global scores for ASSQ Sleep Difficulty and ASBQ sleep behaviors were significantly correlated (r = 0.31; p = 0.014) and not significantly different across age, academic year, or residence. According to the ASSQ, 11% and 24% were classified as having severe or moderate sleep problems, respectively. The ASBQ categorized 62% as having “poor” sleep behaviors. Notable sleep-influencing factors included a high frequency of emotional/cognitive processing of sport-performance issues (46.9%), frequent use of light-emitting devices before bed (90%), training after 7 pm (65%), and the use of sleep medication (19%). Half of the university athletes did not meet the thresholds for adequate sleep, and some may require a referral for clinical sleep issues. The majority of these athletes' sleep behaviors do not promote adequate sleep. The ASSQ shows utility to assess gradations in clinical sleep difficulty; the ASBQ could be used in concert with the ASSQ to discern “cognitive and physiological arousal” targets for use in educational workshops designed to promote optimal sleep hygiene in university athletes.

Sleep and diet patterns of college students during the COVID-19 pandemic lockdowns

Introduction: College students experience high levels of depression, anxiety, and stress during the academic year as they juggle the competing demands of young adulthood and their studies. The COVID-19 pandemic heightened this experience. Healthful diets and sleep patterns are associated with improved physical and mental well-being. Purpose: The goal of this study was to identify if there was a relationship between changes in sleep and diet during the COVID-19 pandemic. Methods: A group of college students was surveyed online using Qualtrics software during the first two months of lockdown restrictions at a large, midwestern university in the United States. Results: More participants reported no changes in diet and increased hours of sleep than reported declines or improvements in diet, or reductions or retained sleep patterns. Participants who maintained their diet were likely to maintain their current sleep pattern. Conclusion: College students demonstrated resilience in healthful behaviors during the first two months of COVID-19 lockdown.

Sleep, stress and aggression: Meta-analyses investigating associations and causality

Prior research suggests that sleep is associated with increased subjective stress and aggression, but important questions remain about the typical magnitude of these relationships, as well as their potential moderators. We therefore conducted the first meta-analysis of this literature. Across 340 associational and experimental studies, significant associations were identified between sleep with both subjective stress (r = 0.307, p < .001) and aggression (r = 0.258, p < .001) in individuals from the general population, as well as between sleep with subjective stress (r = 0.425, p < .001) in individuals with sleep disorders. Experimental sleep restriction also led to increased subjective stress (g = 0.403, p = .017) and aggression (g = 0.330, p = .042). These findings suggest that poorer sleep is associated with - and leads to - heightened levels of subjective stress and aggression. These findings, and their implications, are discussed in relation to neurobiological literature, which highlights the complex interplay between metabolic activity in the brain, hormonal changes, and behavior.

Physical activity and sleep moderate the relationship between stress and screen time in college-aged adults

For undergraduate students, excessive screen time is associated with poorer mental health and greater perceived stress. Objective: The purpose of the present investigation was to determine the potential moderating influence of physical activity and sleep on the relationship between screen time and stress. Participants & Methods: A cross-sectional sample of 513 undergraduate students between Fall 2017 & Spring 2020 were given a questionnaire to assess perceived stress level, physical activity engagement, screen time, and sleep. Results: Stepwise hierarchical regression analyses identified that screen time, sleep, and the three-way interaction between screen time, sleep, and physical activity were associated with stress. Post-hoc decomposition revealed that higher levels of physical activity and sleep both mitigated the relationship between screen time and stress. Conclusions: Findings suggest that modifiable health behaviors such as physical activity and sleep may be important factors for managing the negative effects of screen time on stress in college-aged adults.

Quality of sleep in a sample of Egyptian medical residency

Background

Sleep disturbances among medical staff are common serious entities with devastating consequences. Numerous studies have analyzed the effects of residency on the quality of sleep of the medical trainees in various specialties, but only few studies were conducted in Egypt.

Results

One hundred fifty medical residents from various medical and surgical specialties who work in the hospitals of Ain Shams University, Egypt, agreed to participate in our study. Sociodemographic and work-related data were collected by a semi-structured sheet. Sleep quality was assessed by self-administered questionnaire—Pittsburgh Sleep Quality Index (PSQI). According to the PSQI, 96.7% of the residents had poor sleep quality with mean PSQI score of 10.4 ± 2.5. No statistically significant difference was detected among the different specialties. Poorer sleep quality was more frequent among senior residents who spent longer duration in residency. The number of hours of sleep before residency and the number of days off during residency were the main predictors of total PSQI score and determinants of sleep quality

Conclusions

Poor sleep quality is highly prevalent among medical residents and is associated with work-related factors. It is necessary to consider residents’ sleep estate and conduct more analyses to diagnose, treat, and improve their sleep quality.

Insomnia Symptoms, Sleep Hygiene, Mental Health, and Academic Performance in Spanish University Students: A Cross-Sectional Study

Background: Insomnia has been associated with decreased academic performance and unhealthy behaviors in university students. Although many studies have analyzed sleep phenomenology among this population, only few have focused on insomnia and its related variables. In addition, such studies do not always include a clinical interview or a specific and validated instrument for measuring insomnia. This study aimed to explore the prevalence of insomnia symptoms and the relationship between insomnia and health habits, mental health, and academic performance in a large university student sample. Methods: Five hundred and eighty-two students were recruited from the University of Granada, Spain. Data were collected through an online survey with questions on sociodemographic and academic data and health habits as well as the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Sleep Hygiene Index, and Sleepiness, Depression, Anxiety, and Stress Scales. A multiple regression analysis explored the relationship between academic performance, health habits, mood state, and insomnia symptoms. Results: The prevalence of students with symptoms of insomnia was high (39.7%). A multiple logistic regression analysis revealed that depression, sleep hygiene, stress and anxiety were significant predictors of insomnia symptoms. Multivariate analyses revealed that subjective insomnia symptoms, sleep efficiency, and depression were significantly correlated with academic performance in a dependent way. Conclusions: In university students, anxiety, stress, and poor sleep hygiene are risk factors for insomnia, which plays an important role in academic performance. Promoting sleep and mental health could be a potentially effective way to improve their academic performance.

Stress and Sleep Disorders in Polish Nursing Students During the SARS-CoV-2 Pandemic—Cross Sectional Study

Introduction

The world pandemic of the virus SARS-CoV-2 , which causes COVID-19 infection was announced by the World Health Organization (WHO) on March 11, 2020. Due to the restrictions that were introduced in order to minimize the spread of the virus, people more often suffer from stress, depression, anxiety, and sleep disorders. The aim of this study was evaluation of the stress levels and sleep disorders among nursing students during the pandemic SARS-CoV-2 .

Materials and Study Methods

This is a cross-sectional study conducted among 397 nursing students on March 2020. The research tools used were original questionnaires, Perceived Stress Scale (PSS10), and the Athenian Insomnia Scale (AIS), as well as Coping with Stress Inventory (MiniCOPE).

Results

Respondents felt a high level of stress, which occurred in 68.8% of interviewees regarding whether there was a danger of contracting COVID-19. Respondents experienced 84% stress levels when a family member suffered from COVID-19. Sleep disorders were determined mainly by the fear of infection and contact with someone who might be infected with the virus. Nursing students who felt a high level of stress often suffered from sleep disorders (70.2%) more frequently than students who felt a low or average stress level (30.4%). The respondents decided to cope with stress by denial, taking psychoactive substances, ceasing action, or blaming themselves. The greater the intensity of stress experienced by students, the more often they undertook avoidance behaviors or showed helplessness.

Conclusion

During the pandemic, students experienced severe stress, which resulted in sleep disorders and avoidance behaviors.

Family Cohesion and Sleep Disturbances During COVID-19: the Mediating Roles of Security and Stress

Despite the increase in proximity to one's family amid university closures during the COVID-19 pandemic, the mechanisms underlying how family cohesion influenced students' sleep remain understudied. Using a large sample of college students in China (N = 1,178) during the COVID-19 pandemic, the current study examined the serial mediating roles of sense of security and perceived stress on the effect of family cohesion on sleep disturbance. Generalized linear modeling serial mediation analysis with 1,000 resampled bootstrapping methods showed that sense of security and perceived stress were negatively and positively associated with sleep disturbance, respectively. Furthermore, sense of security and perceived stress fully mediated the indirect effect of family cohesion on sleep disturbances. Implications and conclusions are discussed.

Preexisting Depression and Daytime Sleepiness in Women and Men

BACKGROUND

Sleep problems can persist following the treatment of depression and remission of symptoms. The extent to which having a previous history of depression may be associated with current daytime sleepiness is largely unknown.

METHODS

Data were obtained from the spring 2017 American College Health Association-National College Health Assessment (ACHA-NCHA) survey (92 institutions) which assessed self-reported health in U.S. college students (n = 41,670). Among the sample, 93.5% were 18-24 year of age, and 69.6% women. Logistic regression estimated the association between reported prior lifetime diagnosis of depression and daytime sleepiness from the past 7 days, while adjusting for depressive symptoms and antidepressant use from the past year. Unadjusted and adjusted logistic regression models stratified by gender were performed.

RESULTS

Among those who reported problems with sleepiness, 31.6% women and 19.4% men had a preexisting depression diagnosis. Individuals with preexisting depression were more likely than those without this diagnosis to report sleepiness problems (women: OR = 1.4, CI = 1.3-1.6, p < .001; men: OR = 1.2, CI = 1.0-1.4, p < .01). However, this association differed significantly by gender, with women with a preexisting depression diagnosis having a 13.0% greater likelihood of sleepiness compared to men.

CONCLUSIONS

Those with a preexisting depression diagnosis, and specifically women, may be at risk for daytime sleepiness even in the absence of current depressive mood-related symptoms. Given that many individuals are at risk for daytime sleepiness, mental health initiatives, including those on college campuses, should incorporate sleep hygiene within their programming.

Greater variability in daily sleep efficiency predicts depression and anxiety in young adults: Estimation of depression severity using the two-week sleep quality records of wearable devices

OBJECTIVES

Sleep disturbances are associated with both the onset and progression of depressive disorders. It is important to capture day-to-day variability in sleep patterns; irregular sleep is associated with depressive symptoms. We used sleep efficiency, measured with wearable devices, as an objective indicator of daily sleep variability.

MATERIALS AND METHODS

The total sample consists of 100 undergraduate and graduate students, 60% of whom were female. All were divided into three groups (with major depressive disorder, mild depressive symptoms, and controls). Self-report questionnaires were completed at the beginning of the experiment, and sleep efficiency data were collected daily for 2 weeks using wearable devices. We explored whether the mean value of sleep efficiency, and its variability, predicted the severity of depression using dynamic structural equation modeling.

RESULTS

More marked daily variability in sleep efficiency significantly predicted levels of depression and anxiety, as did the average person-level covariates (longer time in bed, poorer quality of life, lower extraversion, and higher neuroticism).

CONCLUSION

Large swings in day-to-day sleep efficiency and certain clinical characteristics might be associated with depression severity in young adults.

Perceived stress and symptoms of post-traumatic stress disorder in nurses: A moderated mediation model of maladaptive cognitive emotional regulation and psychological capital

Nurses often face a variety of work-related and life-related stresses that make them more prone to symptoms of post-traumatic stress disorder (PTSD), yet the underlying mechanism of this association is poorly understood. To address this research gap, we investigated the mediating role of maladaptive cognitive emotion regulation strategies in the relationship between perceived stress and PTSD symptoms, and explored whether psychological capital could moderate the direct or indirect effects between perceived stress and PTSD symptoms. Nurses (N = 723) completed a questionnaire about perceived stress, PTSD symptoms, maladaptive cognitive emotion regulation strategies and psychological capital. After controlling for gender, age and work department, perceived stress was positively correlated with PTSD symptoms. Maladaptive cognitive emotion regulation strategies partially mediated this relationship. Psychological capital moderates the effects of perceived stress and maladaptive cognitive emotion regulation strategies on PTSD symptoms. Specifically, the positive correlation between perceived stress and PTSD symptoms was stronger among nurses with low levels of psychological capital than among nurses with high levels of psychological capital. At the same time, the positive correlation between maladaptive cognitive emotion regulation strategies and PTSD symptoms was stronger in nurses with a low level of psychological capital. Therefore, cognitive strategies and interventions oriented toward psychological capital may alleviate the PTSD symptoms of nurses in stressful situations.

Bedtime repetitive negative thinking moderates the relationship between psychological stress and insomnia

Research suggests that psychological stress is associated with insomnia, but there is limited research on vulnerabilities that might amplify this association, particularly in college students. Based on a sample of 507 undergraduates, the current study demonstrates that the observed positive correlation between self-perceived stress and insomnia severity is moderated by the tendency to engage in repetitive negative thinking (RNT) at bedtime. Additionally, separate analyses of those who scored below/above the threshold for insomnia (non-insomniacs vs. insomniacs) revealed that the interaction between stress and these negative bedtime cognitions differed qualitatively between the two groups. In insomniacs, the stress-insomnia relationship was dampened for those with lower levels of bedtime RNT, but amplified for those with higher levels. For non-insomniacs, the stress-insomnia relationship was stronger for those with minimal bedtime RNT, while higher levels of bedtime RNT appeared to overshadow this association. To develop a better understanding of the contribution of stress and RNT to clinically relevant levels of insomnia, future studies should take into account the dissimilar patterns of moderation seen in non-insomniacs and insomniacs, either through prospective screening or separate analyses. Findings from the current study suggest that insomnia treatments that can simultaneously reduce stress and address bedtime RNT may be optimal.

Association between Stress and Metabolic Syndrome and its Mediating Factors in University Students

OBJECTIVES

In this study, we evaluated the association between perceived stress and indicators of metabolic syndrome and how this association is mediated by sleep problems, unhealthy eating habits, and night eating syndrome, in addition to serum levels of ghrelin and cortisol in university students.

METHODS

We recruited 192 students from a public university in Mexico. Weight, height, waist circumference and blood pressure were taken in accordance with standard protocols. Validated questionnaires were used to assess perceived stress, sleep quality and eating habits. Fasting blood samples were taken to measure ghrelin, cortisol, triglycerides, glucose and HDL-C.

RESULTS

Path Analysis indicated direct positive effects of stress over PSQI (β = 0.341) and NES (β = 0.443); PSQI over NES (β = 0.233) and NES over glucose (β = 0.170), triglycerides over LDL-C (β = 0.215), waist circumference over SBP (β = 0.259). Likewise, standardized negative regression weights of PSQI over Diet Quality Index (β = -0.239) and ghrelin concentrations (β = -0.132), ghrelin over Diet Quality Index (β = -0.188) and waist circumference (β = -0.147). Diet Quality Index over triglycerides (β = -0.184); sleep duration over systolic blood pressure (β = -0.242); waist circumference over HDL-C (β = -0.256).

CONCLUSION

Psychological stress leads to increased indicators of MetS via decreased sleep quality, inadequate eating habits and eating behavior in university students.

Self-compassion and sleep quality: Examining the mediating role of taking a proactive health focus and cognitive emotional regulation strategies

Sleep quality (SQ) impacts health yet many university students get poor sleep. Self-compassion (SC)—care for oneself during challenging times—is associated with SQ yet how SC has these effects is unclear. This study cross-sectionally examined whether SC is negatively related to poor SQ and whether proactive health focus and cognitive emotional regulation strategies (CERS) mediate this relationship. University students (N = 193) self-reported SC, proactive health focus, CERS, and SQ. SC negatively associated with poor SQ (r = −0.34) and self-blame mediated this (b = 0.08, 95% CI [0.01, 0.16]). SC may improve SQ through reducing self-blame.

The gray matter volume of bilateral inferior temporal gyrus in mediating the association between psychological stress and sleep quality among Chinese college students

The role of brain regions in the relationship between psychological stress and sleep quality is unclear. This study investigates the neuroanatomical basis of the association between psychological stress and sleep quality. Data were collected using the Pittsburgh Sleep Quality Index, the Psychosomatic Tension Relaxation Inventory, and voxel-based morphometry among 318 healthy students. The results showed that psychological stress was negatively correlated with sleep quality. According to the mediation analysis results, the correlation between psychological stress and sleep quality was partially mediated by the region of the bilateral inferior temporal gyrus. These findings suggest that there is a strong link between sleep quality and psychological stress, highlighting the gray matter volume of the bilateral inferior temporal gyrus related to emotional processing, which plays an essential role in improving sleep quality.

Stress and Sleep Across the Onset of the COVID-19 Pandemic: Impact of Distance Learning on U.S. College Students' Health Trajectories

Study Objectives

This study examined associations between average and intraindividual trajectories of stress, sleep duration, and sleep quality in college students before, during, and after transitioning to online learning due to the COVID-19 pandemic.

Methods

One hundred and sixty-four first-year college students answered twice-weekly questionnaires assessing stress exposure and perception, sleep duration, and sleep quality from January until May, 2020 (N=4,269 unique observations).

Results

Multilevel growth modeling revealed that prior to distance learning, student stress was increasing and sleep duration and quality were decreasing. After transitioning online, students’ stress exposure and perception trajectories immediately and continuously decreased; sleep quality initially increased but decreased over time; and sleep duration increased but then plateaued for the remainder of the semester. Days with higher stress exposure than typical for that student were associated with lower sleep quality, and both higher stress exposure and perception at the transition were linked with simultaneous lower sleep quality. Specific groups (e.g., females) were identified as at-risk for stress and sleep problems.

Conclusion

Although transitioning to remote learning initially alleviated college students’ stress and improved sleep, these effects plateaued, and greater exposure to academic, financial, and interpersonal stressors predicted worse sleep quality on both daily and average levels. Environmental stressors may particularly dictate sleep quality during times of transition, but adaptations in learning modalities may help mitigate short-term detrimental health outcomes during global emergencies, even during a developmental period with considerable stress vulnerability. Future studies should examine longer-term implications of these trajectories on mental and physical health.

Mental Health and Behavior of College Students During the COVID-19 Pandemic: Longitudinal Mobile Smartphone and Ecological Momentary Assessment Study, Part II

BACKGROUND

Since late 2019, the lives of people across the globe have been disrupted by COVID-19. Millions of people have become infected with the disease, while billions of people have been continually asked or required by local and national governments to change their behavioral patterns. Previous research on the COVID-19 pandemic suggests that it is associated with large-scale behavioral and mental health changes; however, few studies have been able to track these changes with frequent, near real-time sampling or compare these changes to previous years of data for the same individuals.

OBJECTIVE

By combining mobile phone sensing and self-reported mental health data in a cohort of college-aged students enrolled in a longitudinal study, we seek to understand the behavioral and mental health impacts associated with the COVID-19 pandemic, measured by interest across the United States in the search terms coronavirus and COVID fatigue.

METHODS

Behaviors such as the number of locations visited, distance traveled, duration of phone use, number of phone unlocks, sleep duration, and sedentary time were measured using the StudentLife mobile smartphone sensing app. Depression and anxiety were assessed using weekly self-reported ecological momentary assessments, including the Patient Health Questionnaire-4. The participants were 217 undergraduate students. Differences in behaviors and self-reported mental health collected during the Spring 2020 term, as compared to previous terms in the same cohort, were modeled using mixed linear models.

RESULTS

Linear mixed models demonstrated differences in phone use, sleep, sedentary time and number of locations visited associated with the COVID-19 pandemic. In further models, these behaviors were strongly associated with increased interest in COVID fatigue. When mental health metrics (eg, depression and anxiety) were added to the previous measures (week of term, number of locations visited, phone use, sedentary time), both anxiety and depression (P<.001) were significantly associated with interest in COVID fatigue. Notably, these behavioral and mental health changes are consistent with those observed around the initial implementation of COVID-19 lockdowns in the spring of 2020.

CONCLUSIONS

In the initial lockdown phase of the COVID-19 pandemic, people spent more time on their phones, were more sedentary, visited fewer locations, and exhibited increased symptoms of anxiety and depression. As the pandemic persisted through the spring, people continued to exhibit very similar changes in both mental health and behaviors. Although these large-scale shifts in mental health and behaviors are unsurprising, understanding them is critical in disrupting the negative consequences to mental health during the ongoing pandemic.

Physical Activity Level, Insomnia and Related Impact in Medical Students in Poland

BACKGROUND

Specific academic environment and time spent on learning may lead to sleep deprivation and a sedentary lifestyle. Insomnia is the most common sleep complaint. The purposes of this study were to describe the prevalence of insomnia in medical students, and to examine physical activity levels and other behavioral factors associated with insomnia in this population group.

METHODS

We included 308 medical students from Poland. The International Physical Activity Questionnaire (IPAQ) was used to assess physical activity levels and the Athens Insomnia Scale (AIS) was used to assess insomnia among students. A multifactor model of analysis was used to analyze variables related to insomnia.

RESULTS

A share of 19.2% of medical students were inactive. Insomnia was reported by 36.8% of students. In the multifactorial model, variables such as smoking cigarettes (ß = 0.21, p < 0.001), consuming energy drinks several times a month (ß = 0.21, p = 0.024), or daily stress (ß = 0.44, p < 0.001) had a negative impact on the quality of sleep of medical students.

CONCLUSIONS

Most medical students are physically active, however, approximately one-third of the medical students experience insomnia. This sleep problem is reported more often in students who experience daily stress or smoke cigarettes.

What Factors Influence the Sleep of On-call Workers?

Objective: On-call work is becoming increasingly common in response to service demands. This study had two aims; 1) describe the demographic profile of on-call workers in Australia, and 2) establish the impacts of on-call work on workers' sleep. Methods: A cross-sectional study was conducted using an online questionnaire completed by Australian on-call workers (n = 228) from various professions. The questionnaire included items on i) demographic and work characteristics, ii) rumination about on-call factors, iii) sleep quantity and quality. Analyses were conducted using mixed effects ordinal regression and multivariable logistic regression. Results: Workers slept <7 hours per night when on-call (80%), and reported sleep was impacted on-call even when no-calls were received (56%). On-call workers rated interruptions to family/leisure time (70%), missing a call (69%), preplanning in case of a call (69%), and not able to make plans (67%) as the main factors they ruminated about. Female on-call workers were more likely to think about the likelihood of being called, report frequent thoughts about what they would need to do if called, and think about interruptions to family/leisure time as a result of a call. Younger workers were more likely to think about the likelihood of being called compared to older adults, however middle-aged workers were less likely to plan for a call compared to younger workers. Conclusions: This study is the first to describe Australia's on-call population, including factors that specifically impact sleep. Future studies should implement tailored education and support strategies to address the unique challenges facing on-call workers.

Feasibility and acceptability of a guided internet-based stress management intervention for university students with high levels of stress: Protocol for an open trial

More than half of university students have high levels of stress. Stress management programs can help students improve coping skills and prevent psychological distress. However, studies have generally targeted all university students regardless of whether they experience high levels of stress or not, and thus more studies are needed to examine the feasibility and acceptability of e-health interventions for students with elevated stress. The present open trial aims to examine the feasibility and acceptability of a guided internet-based stress management program for university students with high levels of stress. In this study, participants are recruited via e-mail, newsletters, and flyers from four universities in the Netherlands to participate in a guided internet-based stress management program. Guidance is delivered by e-coaches who provide weekly asynchronous text-based motivational feedback after each module is completed. Primary outcomes are satisfaction with the intervention, assessed by the Client Satisfaction Scale (CSQ-8), and usability, assessed by the System Usability Scale (SUS-10). Secondary outcomes are perceived stress, quality of life, and depression, assessed by the Perceived Stress Scale (PSS-10), the EuroQol- 5 Dimension- 5 Level Scale (EQ- 5D- 5L), and the Patient Health Questionnaire (PHQ-9) respectively. Adherence rates to the program are assessed by examining the number of completed modules, time spent on the platform, and completed exercises. The Caring Universities Project was funded in (September 2019). In June 2020, the project was officially announced to the students and recruitment began immediately. As of October 2020, recruitment continues. The expected date of the publication of the results is in 2021. It is expected that the results of the proposed study will be informative for designing and implementing e-health interventions in higher education. Moreover, it is assumed that the findings will contribute to the growing literature on internet interventions by yielding preliminary evidence related to the feasibility and acceptability of an online stress management program.
