Mediating role of psychological resilience between social support and negative emotions in nursing interns in the post-COVID-19 era: A cross-sectional survey

Background: The increasing burden of mental health problems continues in the post-COVID-19 era, and nursing interns were particularly likely to experience negative emotions during the pandemic. Both psychological resilience and social support affect negative emotion, but the relationship among the three has not been explored in nursing interns in the postpandemic era. Objectives: To explore the current prevalence of negative emotions among nursing interns and the role of psychological resilience in mediating the relationship between social support and negative emotions in the postpandemic era. Methods: A cross-sectional survey of 788 nursing interns was conducted. The instruments included Psychological Resilience Scale, Social Support Scale, Beck Anxiety Scale and Beck Depression Scale. Structural equation modeling was applied to analyze the mediating role of psychological resilience. Results: The prevalence of anxiety disorder among nursing interns was 24.7%, while that of depression was 10.5%. Pearson correlation analysis showed that both social support and psychological resilience negatively correlated with negative emotions, while psychological resilience positively correlated with social support. Psychological resilience showed a partial mediating effect (53.9%) between social support and negative emotion, with an effect value of −0.1456. Conclusion: Psychological resilience and social support protect nursing students from negative emotions, and psychological resilience partially mediates the relationship between social support and negative emotion in the postpandemic era. © 2023 Wiley Periodicals LLC.

Effects of negative emotions and information perceived value on residents' risk perception during the COVID-19 pandemic: An empirical survey from China.

Background: The COVID-19 pandemic has spread rapidly and heavily hit the globe, and the mutation and transmission speed of the coronavirus have accelerated so that the world is still in danger. Thus, this study aims to investigate the participants' risk perception and explore the associations of risk perception of COVID-19 with negative emotions, information value perception and other related dimensions. Methods: A cross-sectional, population-based online survey was conducted from April 4 to 15, 2020, in China. A total of 3,552 participants were included in this study. A descriptive measure of demographic information was used in this study. Multiple regression models and moderating effect analysis were used to estimate the effect of potential associations of risk perceptions. Results: Those who showed negative emotions (depressed, helplessness, loneliness) and perceived video information in social media to be useful were positively correlated with risk perception, whereas individuals who perceived experts' advice to be useful, shared risk information with friends and thought that their community made adequate emergency preparation reported lower risk perception. The moderating effect of information perceived value (ß = 0.020, p < 0.001) on the relationship between negative emotion and perception of risk was significant. Conclusions: Individual differences in risk cognition during the COVID-19 pandemic were observed in subgroups of age level. Furthermore, the role of negative emotional states, the perceived usefulness of risk information and the sense of security also contributed to improving the public's risk perception. It is crucial for authorities to focus on residents' negative emotions and to clarify misinformation in accessible and effective ways in a timely manner.

"Who Knows Me Understands My Needs": The Effect of Home-Based Telework on Work Engagement.

Purpose: Based on the affective event theory and the theoretical framework of "work environment features-work events-emotional responses-work attitude", this study aims to explore how and when home-based telework negatively affects work engagement by focusing on the dual chain mediating paths of "workplace isolation-negative emotion" and "telepressure-negative emotion", and the moderating role of family-supportive leadership. Methods: A questionnaire survey was used to collect 276 self-reported responses from employees with home-based telework experience in China. Findings: (a) Home-based telework indirectly and negatively affects work engagement through the mediating chain of "workplace isolation-negative emotion"; (b) Home-based telework indirectly and negatively affects work engagement through the mediating chain of "telepressure-negative emotion"; (c) Family-supportive leadership negatively moderates the chain mediating effect of "workplace isolation-negative emotion" and "telepressure-negative emotion" between home-based telework and work engagement. In other words, the higher the level of family-supportive leadership, the weaker the negative effect of home-based telework on work engagement. Originality/Value: This study sheds additional light on the relationship between home-based telework and work engagement by constructing the influence mechanism model of home-based telework on work engagement, in which "workplace isolation-negative emotion" and "telepressure-negative emotion" act as chain mediators, and family supportive leadership as moderator. This study enriches the literature on home-based telework. Practical Implications: The findings indicates that home-based work has indirectly and negatively effects on work engagement through dual chain mediating paths of "workplace isolation-negative emotion" and "telepressure-negative emotion". However, family-supportive leadership can weaken this negative influence. Therefore, organizations need to cultivate family supportive leadership.

A comparative study of well-being, resilience, mindfulness, negative emotions, stress, and burnout among nurses after an online mind-body based intervention during the first COVID-19 pandemic crisis.

Background: To mitigate against the possible adverse effects of stress among nurses due to the COVID-19 outbreak, we designed a 12-week mind-body based online intervention program to promote well-being and prevent stress-related disorders such as burnout. Our study aimed to compare the impact of the intervention on perception of stress, negative emotions, burnout, mindfulness, resilience, and well-being at pretest and 6 months post-intervention and to compare the effect among nurses working at two different hospitals. Methods: We conducted an uncontrolled trial using a convenience sample of nurses working at two hospitals in Mexico: one designated to treat confirmed COVID-19 patients (COVID-hospital) and the other whose patients had a negative COVID-19 test on admission (Non COVID-hospital). The 12 week online intervention consisted of 36 mind-body based micropractices, with subjective well-being as the primary outcome. Secondary outcomes were health perception, resilience, mindfulness, negative emotions, stress, and burnout. Results: A pretest survey was completed by 643 nurses. Of the remaining valid responses, 82% were women, with a mean age of 34.8 (SD = 8.95) years old. For the analysis two groups of nurses were sampled by cluster: a COVID-hospital group of 429 (67%) nurses, and a non-COVID Hospital group of 214 (33%) nurses. The proportion lost to follow-up was 71% at postest (n = 188) and 42% at 6 months follow-up (n = 371). At pretest, non-COVID hospital nurses had lower subjective well-being and higher burnout than their COVID hospital counterparts. At postest, non-COVID hospital nurses displayed more negative emotions than their COVID hospital peers. At 6 months post-intervention, nurses experienced improved mindfulness, reduced negative emotions and stress, but a decrease in subjective well-being and resilience. Nurses working at the non-COVID hospital had significantly higher mean scores for burnout than those working at the COVID hospital. Conclusion: The results of our study suggest that our online mind-body interventions can help to reduce stress and negative emotions, yet the effects on subjective well-being and resilience are uncertain. Further research is needed to gain a better understanding of their potential mechanisms and the associated efforts of such online interventions.

A Study on the Relationship between Internet Overdependence and Anger Response among Young Adults during COVID-19 Pandemic: Moderating Effect on Negative Emotions.

The aim of this study is to examine how Internet dependence affects anger responses during the COVID-19 pandemic. Owing to social distancing policies, Internet dependence has intensified, and the prevalence of anger has significantly increased. To understand this phenomenon and draw some implications, the "frustration-aggression hypothesis" was utilized for the theoretical framework and anger response was categorized into functional and dysfunctional anger responses. An analysis shows that overdependence on the Internet has a positive effect on the dysfunctional anger response. At the same time, other negative emotions replace anger, reducing the possibility of a dysfunctional anger response. Accordingly, a need for a constant effort to understand the circumstances of the young generation living in the "new normal" is emphasized; moreover, this paper suggests some theoretical and practical implications.

The association between physical activity and mental health in medical postgraduates in China during COVID-19 pandemic.

Background: Chinese medical postgraduates (CMPs) are a special subpopulation that has a great risk of mental health due to high workload, and heavy academic and clinical pressure during the COVID-19 pandemic. Physical activity has been demonstrated to be positive for the mental health of human being. However, little is known about the risks to mental health among CMPs as well as the potential effects of physical activity on mental health in CMPs during the COVID-19 pandemic. Aims: In the present study, the aims are to (1) investigate the levels of PA and mental health that CMPs had; (2) to identify the potential factors that contribute to mental health among CMPs; (3) to explore the potential effects of PA on the mental health in CMPs. Methods: The survey was conducted online across 25 provinces of mainland China in 28 medical colleges or universities with structured questionnaires. Physical Activity Rating Scale-3 (PARS-3), Depression, Anxiety, Stress Scales (DASS-21), and General Self-Efficacy Scale (GSES) were employed to assess the levels of PA, Negative emotional states, and self-efficacy of the participants, respectively. Resilience was evaluated using Connor-Davidson Resilience Scale (CD-RISC). The chi-square and Wilcoxon rank-sum tests were used to compare inter-group differences in demographic data and mental health conditions. Spearman's rank correlation test and partial correlation analysis were used to assess associations between exercise scores and mental health. Results: We found some socio-demographic variables such as the location, education levels of parents and the levels of degrees they are training had potential effects on outcomes of mental health among 2,217 CMPs (P < 0.05); furthermore, we also found that PA was negatively correlated with the negative emotion (r = -0.045, P < 0.05) such as depression (r = -0.052, P < 0.05), anxiety and stress, (r = -0.051, P < 0.05) but positively correlated with the self-efficacy (r = 0.143, P < 0.001) and resilience (r = 0.192, P < 0.001) among Chinese postgraduate medical students. Conclusion: We concluded that for Chinese postgraduate medical students, taking part in physical activity would depress negative emotions such as depression, anxiety, and stress, but improve their self-efficacy and resilience, which will benefit them in completing their studies and training.

The Relationship between Self-Concept and Negative Emotion: A Moderated Mediation Model.

Background: Emotional problems such as depression and anxiety are very serious among college students, especially during the COVID-2019 pandemic. The present study aimed to explore the mediating role of resilience in the relationship between self-concept and negative emotion, and the moderating role of exercise intensity in the direct and indirect effect of self-concept on negative emotion among college students. Methods: A total of 739 Chinese college students aged between 18 and 25 years (M = 20.13; SD = 1.67) were selected to complete the Tennessee Self-Concept Scale (TSCS), the Depression Anxiety Stress Self Rating Scale, the Adolescent Psychological Resilience Scale, and the Physical Exercise Scale (PARS-3) to assess self-concept, negative emotions, psychological resilience, and exercise intensity, respectively. Hayes' PROCESS macro for SPSS was used to test the relationships among these variables. Results: Self-concept was negatively correlated with negative emotions; psychological resilience partially mediated the association between self-concept and negative emotions; exercise intensity moderated the effect of self-concept on negative emotions, and college students with low intensity physical activity would strengthening the association between self-concept and psychological resilience, psychological resilience, and negative emotions. Conclusions: Psychological resilience is a critical mediating mechanism through which self-concept is associated with negative emotions among college students, and exercise intensity plays a role as a moderating variable in the direct and indirect influence of self-concept on negative emotions. Implications for preventing or reducing negative emotions are discussed.

Chinese College Students' Physical-Exercise Behavior, Negative Emotions, and Their Correlation during the COVID-19 Outbreak.

BACKGROUND: In the period of the COVID-19 pandemic, the level of college students' physical exercise, the detection rate of negative emotions, and their correlation should attract extensive attention. Therefore, this study aimed to explore the correlation between college students' physical exercise and negative emotions. METHODS: Data were collected via a web-based cross-sectional survey. A questionnaire survey was conducted among 3118 college students from five universities in Shanghai in March 2022. In addition to sociodemographic information, measures included Physical Activity Rating Scale (PARS-3) and Depression Anxiety Stress Scale (DASS). The chi-squared test and logistic regression were used to analyze the differences and test the relative risk of negative emotions caused by different amounts of physical exercise. RESULTS: Most students (66.1%) performed a small amount of physical exercise. Male students' physical-exercise level was higher than female students', and the detection rate of negative emotions was lower than that of female students. Moderate and low physical-exercise levels were associated with a higher risk of depression (beta of 0.289 and 0.345, respectively) and anxiety (beta of 0.301 and 0.418) symptoms than high physical-exercise level. CONCLUSIONS: The anxiety symptoms of college students were significant during the COVID-19 pandemic period. The physical-exercise behavior of college students was closely related to negative emotions, and the weakening of physical-exercise behavior was one of the factors that induced negative emotions in college students.

The Impact of Mortality Salience, Negative Emotions and Cultural Values on Suicidal Ideation in COVID-19: A Conditional Process Model.

As suicides incurred by the COVID-19 outbreak keep happening in many countries, researchers have raised concerns that the ongoing pandemic may lead to "a wave of suicides" in society. Suicidal ideation (SI) is a critical factor in conducting suicide intervention and also an important indicator for measuring people's mental health. Therefore, it is vital to identify the influencing factors of suicidal ideation and its psychological mechanism during the outbreak. Based on the terror management theory, in the present study we conducted a social media big data analysis to explore the joint effects of mortality salience (MS), negative emotions (NE), and cultural values on suicidal ideation in 337 regions on the Chinese mainland. The findings showed that (1) mortality salience was a positive predictor of suicidal ideation, with negative emotions acting as a mediator; (2) individualism was a positive moderator in the first half-path of the mediation model; (3) collectivism was a negative moderator in the first half-path of the mediation model. Our findings not only expand the application of the terror management theory in suicide intervention but provide some insights into post-pandemic mental healthcare. Timely efforts are needed to provide psychological interventions and counseling on outbreak-caused negative emotions in society. Compared with people living in collectivism-prevailing regions, those living in individualism-prevailing regions may be more vulnerable to mortality salience and negative emotions and need more social attention.

The Influence of Vicarious Fear-Learning in "Infecting" Reactive Action Inhibition.

Since the dawn of cognitive neuroscience, emotions have been recognized to impact on several executive processes, such as action inhibition. However, the complex interplay between emotional stimuli and action control is not yet fully understood. One way to measure inhibitory control is the stop-signal task (SST), which estimates the ability to cancel outright an action to the presentation of a stop signal by means of the stop-signal reaction times (SSRTs). Impaired as well as facilitated action control has been found when faced with intrinsic emotional stimuli as stop signals in SSTs. Here, we aimed at investigating more deeply the power of negative stimuli to influence our action control, testing the hypothesis that a previously neutral stimulus [i.e., the image of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)], which has been conditioned through vicarious fear learning, has the same impact on reactive action inhibition performance as an intrinsically negative stimulus (i.e., a fearful face or body). Action control capabilities were tested in 90 participants by means of a SST, in which the stop signals were represented by different negative stimuli. Results showed that the SARS-CoV-2 image enhanced the ability to suppress an ongoing action similarly to observing fearful facial expressions or fearful body postures. Interestingly, we found that this effect was predicted by impulsivity traits: for example, the less self-control the participants had, the less they showed emotional facilitation for inhibitory performance. These results demonstrated that vicarious fear learning has a critical impact on cognitive abilities, making a neutral image as threatening as phylogenetically innate negative stimuli and able to impact on our behavioral control.

Intelligent Recognition and Analysis of Negative Emotions of Undergraduates Under COVID-19.

Background: The outbreak and spread of COVID-19 has brought a tremendous impact on undergraduates' study and life, and also caused anxiety, depression, fear and loneliness among undergraduates. If these individual negative emotions are not timely guided and treated, it is easy to cause the amplification of social negative emotions, resulting in individual and collective irrational behavior, and ultimately destroy social stability and trust foundation. Therefore, how to strengthen the analysis and guidance of negative emotions of undergraduates has become an important issue to be urgently solved in the training of undergraduates. Method: This paper presents a weight and structure double-determination method. Based on this method, a Radial Basis Function Neural Networks (RBFNN) classifier is constructed for recognizing negative emotions of undergraduates. After classifying the input psychological crisis intervention scale samples by the RBFNN classifier, recognition of negative emotions for undergraduates are divided into normal, mild depression, moderate depression and severe depression. Experiments: Afterwards, we analyze negative emotions of undergraduates and give some psychological adjustment strategies. In addition, the experiment results demonstrate that the proposed method has a good performance in terms of classification accuracy, classification time and recognition rate of negative emotions among undergraduates.

Mechanism of Negative Emotions of the Elderly in Normalization Period of COVID-19: A Mediated Mediation Model.

To explore the mechanism of negative emotions of the elderly in normalization period of COVID-19. The self-rating Depression Anxiety Stress Scale, epidemic attention scale, subjective economic status scale and physical health perception scale were used to investigate 318 elderly people in 2021. There were significant differences in negative emotions among the elderly in Henan in China with different gender, education background, medical insurance and whether they contacted suspected cases (all P < 0.05), but there was no significant difference on religious belief (P > 0.05); Attention to epidemic information was positively correlated with negative emotion (r = 0.492, P < 0.01), and negatively correlated with subjective economic status (r = -0.138, P < 0.05); Negative emotions were negatively correlated with subjective economic status (r = -0.455, P < 0.01) and health perception (r = -0.277, P < 0.01); health perception was no significant correlation with epidemic attention(r = -0.047, P > 0.05) and subjective economic status (r = -0.033, P > 0.05). Bootstrap test found that epidemic attention can significantly predict negative emotion of the elderly (ß = 0.492, P < 0.001), subjective economic status played a partial mediating role between epidemic attention and negative emotions (ß = 0.438, -0.395, P < 0.001), and health perception moderated the first half of the mediating path (ß = 0.403, P < 0.001, 95% CI = [0.286~0.521]). Epidemic attention has a significant positive impact on the negative emotions of the elderly in Henan during normalization period of COVID-19, and it has effect indirectly through subjective economic status; health perception plays a moderator role in the impact of epidemic attention on subjective economic status.

Relationship Between Negative Emotions and Job Burnout in Medical Staff During the Prevention and Control of the COVID-19 Epidemic: The Mediating Role of Psychological Resilience.

We herein investigated the relationship between psychological status and the various emotions of medical staff during the prevention and control of coronavirus disease 2019 (COVID-19) epidemic. In this study, the convenience sampling method was used to select medical staff members as participants, and a cross-sectional study design was implemented. The instruments included the Burnout Clinical Subtype Questionnaire (BCSQ-36), the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), the self-rated 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR16), and the Self-rating Anxiety Scale (SAS). In total, 876 medical staff members were selected in this study. The CD-RISC-10 was negatively correlated with all other scales (P < 0.01). The hierarchical regression coefficients of the SAS and QIDS-SR16 against the BCSQ-36 mediated by the CD-RISC-10 were P < 0.01, and the significance of the F values in all hierarchical regression equations was P < 0.01 (Sobel test, P < 0.01). Medical staff burnout during the COVID-19 epidemic was affected by anxiety and depression, and psychological resilience had a mediating role. Attending to changes in the negative emotions of medical staff and improving their psychological resilience are beneficial to alleviate job burnout.

A Neural Predictive Model of Negative Emotions for COVID-19

The long-lasting global pandemic of Coronavirus disease 2019 (COVID-19) has changed our daily life in many ways and put heavy burden on our mental health. Having a predictive model of negative emotions during COVID-19 is of great importance for identifying potential risky population. To establish a neural predictive model achieving both good interpretability and predictivity, we have utilized a large-scale (n =542) longitudinal dataset, alongside two independent samples for external validation. We built a predictive model based on psychologically meaningful resting state neural activities. The whole-brain resting-state neural activity and social-psychological profile of the subjects were obtained from Sept. to Dec. 2019 (Time 1). Their negative emotions were tracked and re-assessed twice, on Feb 22 (Time 2) and Apr 24 (Time 3), 2020, respectively. We first applied canonical correlation analysis on both the neural profiles and psychological profiles collected on Time 1, this step selects only the psychological meaningful neural patterns for later model construction. We then trained the neural predictive model using those identified features on data obtained on Time 2. It achieved a good prediction performance (r =0.44, p =8.13 ×10-27). The two most important neural predictors are associated with self-control and social interaction. This study established an effective neural prediction model of negative emotions, achieving good interpretability and predictivity. It will be useful for identifying potential risky population of emotional disorders related to COVID-19. IEEE

What matters for adolescent suicidality: Depressive symptoms or fixed mindsets? Examination of cross-sectional and longitudinal associations between fixed mindsets and suicidal ideation.

BACKGROUND: Fixed mindsets or beliefs about the non-malleability of self-attributes are linked to a wide range of negative psychological outcomes. Its association with suicidal ideation (SI) among young people has not been explored. OBJECTIVES: To examine the association of fixed mindsets of depression, anxiety, and stress and SI; and its mediating role underlying the association between depression and SI. METHODS: A sample of 1393 adolescents (Mage  = 13.04, SD = 0.85, 640 boys) from 11 middle schools voluntarily participated in a two-wave longitudinal study before and during the COVID-19 pandemic with a 9-month interval. RESULTS: Both depressive symptoms and fixed mindsets were positively and significantly associated with concurrent and future suicidality, after controlling for demographic and socioeconomic status and previous SI. Participants with stronger fixed mindsets were more likely to have SI than those with only depressive symptoms. Also, fixed mindsets mediated the association between depressive symptoms and SI in both cross-sectional and longitudinal models. CONCLUSION: The current study provides empirical evidence of the effects of fixed mindsets and SI and the mediating role of fixed mindset between depressive symptoms and SI among young people. Interventions to foster a growth mindset may enhance hope and reduce suicidality among adolescents.

Reciprocal effects between young children's negative emotions and mothers' mental health during the COVID-19 pandemic.

Objective: To investigate the relations between young children's negative emotions and their mothers' mental health during the COVID-19 pandemic. Background: The COVID-19 pandemic caused the public a certain degree of psychological symptoms, and family environments and relations have been changed dramatically as a result. The relations between young children's negative emotions and their mothers' mental health have not been sufficiently determined for the context of a pandemic or other large-scale crises. Method: A survey was administrated on 8119 Chinese mothers of 3- to 6-year-old children with the Symptom Checklist 90 and the Child Negative Emotion Questionnaire. Results: The canonical correlation results indicated that there were covariation trends between young children's anger and their mother's obsessive-compulsive symptoms and hostility, children's fear and mothers' phobic anxiety, and children's tension and mothers' interpersonal sensitivity and depression. These correlations were all positively significant. Conclusion: During the COVID-19 pandemic, the predictive power of young children's negative emotions to their mothers' mental health was greater than that of the reverse. Implications: This study provides a scientific guidance on the regulation of young children's negative emotions and the improvement of mothers' mental health during the pandemic as well as potential emergencies in the future.

How Positive and Negative Emotions Promote Ritualistic Consumption Through Different Mechanisms.

Ritualistic consumption refers to integrating ritual elements into the process of product design and usage. By conducting three studies, we find that ritualistic consumption can offer new and interesting experiences and help consumers gain a sense of control. Both positive and negative emotions can promote ritualistic consumption tendencies. However, their underlying psychological mechanisms are different. Specifically, positive emotion can arouse consumers' desire for interesting experience and thus promotes their preference for ritualistic consumption, while negative emotion can arouse consumers' need for control and thus promote their preference for ritualistic consumption. Our research results offer a theoretical contribution and practical inspiration for emotional marketing.

Irrational Consumption during the COVID-19 Period.

The outbreak of the COVID-19 pandemic has severely impacted the world economy and has, most presumably, exerted a great deal of stress on citizens, in turn leading to the call for timely assessments of how this period might actually impact individuals at the level of everyday well-being and in their behaviors such as consumer decisions. Through one pilot study and two online survey studies, we tentatively investigated this latter question, and demonstrated that the COVID-19 pandemic may increase perceived stress and impair individuals' sleep quality, which in turn impels their irrational consumption. This research provides preliminary evidence for the impact of the present pandemic on irrational consumption and contributes to the literature on stress and consumer behavior.

[Mental Health Status and Its Influencing Factors among College Students during the Epidemic of Coronavirus Disease 2019:A Multi-center Cross-sectional Study].

Objective To measure the prevalence of mental health symptoms and identify the associated factors among college students at the beginning of coronavirus disease 2019(COVID-19)outbreak in China. Methods We carried out a multi-center cross-sectional study via snowball sampling and convenience sampling of the college students in different areas of China.The rates of self-reported depression,anxiety,and stress and post-traumatic stress disorder(PTSD)were assessed via the 21-item Depression-Anxiety-Stress Scale(DASS-21)and the 6-item Impact of Event Scale-Revised(IES-6),respectively.Covariates included sociodemographic characteristics,health-related data,and information of the social environment.Data pertaining to mental health service seeking were also collected.Multivariate Logistic regression analyses were performed to identify the risk factors. Results A total of 3641 valid questionnaires were collected from college students.At the beginning of the COVID-19 outbreak,535(14.69%)students had negative emotions,among which 402(11.04%),381(10.49%),and 171(4.90%)students had the symptoms of depression,anxiety,and stress,respectively.Meanwhile,1245(34.19%)college students had PTSD.Among the risk factors identified,male gender was associated with a lower likelihood of reporting depression symptoms(AOR=0.755,P=0.037],and medical students were at higher risk of depression and stress symptoms than liberal arts students(AOR=1.497,P=0.003;AOR=1.494,P=0.045).Family support was associated with lower risks of negative emotions and PTSD in college students(AOR=0.918,P<0.001;AOR=0.913,P<0.001;AOR=0.899,P<0.001;AOR=0.971,P=0.021). Conclusions College students were more sensitive to public health emergencies,and the incidence of negative emotions and PTSD was significantly higher than that before the outbreak of COVID-19.More attention should be paid to female college students who were more likely to develop negative emotions.We should strengthen positive and proper propaganda via mass media and help college students understand the situation and impact of COVID-19.Furthermore,we should enhance family support for college students.The government and relevant agencies need to provide appropriate mental health services to the students under similar circumstances to avoid the deterioration of their mental well-being.

Daily Associations Between Adolescent Sleep and Socioemotional Experiences During an Ongoing Stressor.

PURPOSE: Ongoing stress can result in sleep disturbances and daytime socioemotional difficulties. Data on how sleep and daytime socioemotional functioning may be bidirectionally related to one another in the midst of an ongoing stressor are limited, particularly during adolescence, a developmental period when risk for the onset of mental health difficulties and sleep disturbances is high. METHODS: Participants (N = 459, ages of 13-18 years) were recruited from across the United States and completed an intake survey and one week of daily reports beginning 2 weeks after COVID-19 was declared a national emergency. Participants reported on their daily post-traumatic stress symptoms, positive and negative affect, loneliness, sleep onset difficulties, nightmares, sleep quality, and time in bed. RESULTS: Lagged hierarchical linear models adjusting for age, sex, socioeconomic status, race, ethnicity, medication use, medical conditions, and ongoing stressors were estimated to examine bidirectional associations between night-time sleep and next-day mental health. Poorer sleep quality and more nightmares at night predicted higher next-day negative affect, and greater daytime negative affect predicted lower sleep quality and a greater likelihood of having nightmares the following night. Poor sleep quality predicted greater next-day post-traumatic stress, which, in turn, predicted poorer sleep quality the following night and more difficulties falling asleep. Poor sleep quality and a longer time in bed also predicted greater next-day loneliness. DISCUSSION: Overall, these findings provide insight into how sleep disturbances and socioemotional difficulties unfold during a major life stressor in an adolescent sample.
