The mediating role of psychological capital in the association between life satisfaction and depressive and anxiety symptoms among Chinese medical students during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND: Although life satisfaction is a predictor of depressive and anxiety symptoms, the mechanisms underlying this association are poorly understood. This study examined how psychological capital (PsyCap), a positive psychological state, mediated the association between life satisfaction and depressive and anxiety symptoms among Chinese medical students during the COVID-19 pandemic. METHODS: A cross-sectional survey was conducted at three medical universities in China. A self-administered questionnaire was distributed to 583 students. Depressive symptoms, anxiety symptoms, life satisfaction, and PsyCap were measured anonymously. A hierarchical linear regression analysis was performed to explore the effects of life satisfaction on depressive and anxiety symptoms. Asymptotic and resampling strategies were used to examine how PsyCap mediates the association between life satisfaction and depressive and anxiety symptoms. RESULTS: Life satisfaction was positively associated with PsyCap and its four components. There were significant negative associations between life satisfaction, psychological capital, resilience, optimism, and depressive and anxiety symptoms among medical students. Self-efficacy was negatively associated with depressive and anxiety symptoms. Psychological capital (a×b = -0.3201, BCa 95% CI: -0.3899, -0.2446; a×b = -0.2749, BCa 95% CI: -0.3817, -0.1996), resilience (a×b = -0.2103, BCa 95% CI: -0.2727, -0.1580; a×b = -0.1871, BCa 95% CI: -0.2520, -0.1414), optimism (a×b = -0.2100, BCa 95% CI: -0.3388, -0.1150; a×b = -0.1998, BCa 95% CI: -0.3307, -0.0980), and self-efficacy (a×b = -0.0916, BCa 95% CI: 0.0048, 0.11629; a×b = 0.1352, BCa 95% CI: 0.0336, 0.2117) significantly mediated the association between life satisfaction and depressive and anxiety symptoms. LIMITATIONS: This was a cross-sectional study, and causal relationships between the variables could not be ascertained. Self-reported questionnaire instruments were used for data collection, which may have recall bias. CONCLUSIONS: Life satisfaction and PsyCap can be used as positive resources to reduce depressive and anxiety symptoms among third-year Chinese medical students during the COVID-19 pandemic. Psychological capital and its components (self-efficacy, resilience, and optimism) partially mediated the relationship between life satisfaction and depressive symptoms, and completely mediated the relationship between life satisfaction and anxiety symptoms. Therefore, improving life satisfaction and investing in psychological capital (especially self-efficacy, resilience, and optimism) should be included in the prevention and treatment of depressive and anxiety symptoms among third-year Chinese medical students. Additional attention is needed to pay for self-efficacy in such disadvantageous contexts.

Anyone but Me: Unrealistic Optimism, Emotions and Anxiety in the Face of COVID-19 Pandemic.

The worldwide COVID-19 pandemic (and its consequences, such as lockdown and public health regimes) was a novel and stressful situation for most of people, and, as such, it significantly affected both cognitive and emotional functioning of individuals. In our study, we explored unrealistic optimism bias (the cognitive error giving people a feeling of invulnerability) and any declared preventive behaviours undertaken in order to minimise the risk of contagion. We also measured twelve specific emotions (differing in valence and origin) and the feeling of the anxiety caused by the coronavirus. The results allowed us to confirm the occurrence of unrealistic optimism bias (being significantly stronger for men than women), which correlated negatively with the declared number of preventive behaviours. Unrealistic optimism was also positively correlated with negative automatic emotions and negatively correlated with positive reflective emotions. We created models accounting for the variance of general anxiety, finding significant predictors for both separate groups of younger and older adults (negative emotions, both automatic and reflective; and preventive behaviours). However, there was an effect of positive emotions (both automatic and reflective) having a protective role from the feeling of general anxiety, which was significant for the older group only. Our findings may be a valuable cue for coping with crisis situations.

Self-uniqueness beliefs and adherence to recommended precautions. A 5-wave longitudinal COVID-19 study.

RATIONALE: Research on health-related self-uniqueness beliefs suggested that these beliefs might predict adherence to precautions against COVID-19. OBJECTIVE: We examined if comparative optimism (believing that one is less at less than others), self-superiority (believing that one already adheres better to precautions than others), and egocentric impact perception (believing that adverse events affect oneself more than others) predicted intended adherence to precautions. METHOD: We measured self-reported intentions, optimism for self and others, perceived past adherence by self and others, and perceived impact of the measures and the disease on self and others in a 5-wave longitudinal study in December 2020-May 2021 (N ≈ 5000/wave). The sample was in key respects representative for the Belgian population. We used joint models to examine the relationship between self-uniqueness beliefs and intended adherence to the precautions. RESULTS: Believing that COVID-19 would affect one's own life more than average (egocentric impact perception) was associated with higher intentions to adhere to precautions, as was believing that the precautions affected one's life less than average (allocentric impact perception). Self-superiority concerning past adherence to precautions and comparative optimism concerning infection with COVID-19 were associated with higher intended adherence, regardless of whether their non-comparative counterparts (descriptive norm, i.e., perceived adherence to precautions by others, and personal optimism, respectively) were controlled for. Comparative optimism for severe disease and for good outcome were associated with lower intended adherence if personal optimism was not controlled for, but with higher intended adherence if it was controlled for. CONCLUSION: Self-uniqueness beliefs predict intended adherence to precautions against COVID-19, but do so in different directions.

Temporal aspects of unrealistic optimism and robustness of this bias: A longitudinal study in the context of the COVID-19 pandemic.

Numerous studies on unrealistic optimism (UO) have shown that people claim they are less exposed to COVID-19 infection than others. Yet, it has not been assessed if this bias evolves; does it escalate or diminish when the information about the threat changes? The present paper fills this gap. For 12 months 120 participants estimated their own and their peers' risk of COVID-19 infection. Results show that UO regarding COVID-19 infection is an enduring phenomenon-It was the dominant tendency throughout almost the entire study and was never substituted by Unrealistic Pessimism. While the presence of UO-bias was constant, its magnitude changed. We tested possible predictors of these changes: the daily new cases/deaths, the changes in governmental restrictions and the mobility of participants' community. Out of these predictors, only changes in governmental restrictions proved to be significant- when the restrictions tightened, UO increased.

Self-efficacy and positive thinking as predictors of health-related quality of life in women with stress urinary incontinence.

BACKGROUND: Stress urinary incontinence (SUI), which causes involuntarily leakage of urine, has an impact on many women and may affect self-efficacy, which, in turn, can lead to poor health-related quality of life (QOL). This study aimed to explore the effects of sociodemographic and health information, symptom distress, self-efficacy, and positive thinking on the health-related QOL (general QOL and urinary incontinence-specific QOL) of women with SUI. METHODS: A cross-sectional study design was used. Women with SUI were recruited from the obstetrics and gynecology outpatient department and urodynamics examination room of a hospital by convenience sampling from August 2021 to March 2022. Participants were surveyed on the following questionnaires: Urogenital Distress Inventory, Geriatric Self-efficacy Index for Urinary Incontinence, Positive Thinking Scale, 12-Item Short-Form Health Survey (SF-12), and Incontinence Impact Questionnaire Short Form. RESULTS: Participants (N = 135) had a mean age of 53.76 years old. The mean SF-12 physical component summary score was 48.48 (physical QOL), and the mental component summary score was 46.56 (mental QOL). The urinary incontinence-specific QOL score was 16.01. Women with greater positive thinking and higher self-efficacy for urinary incontinence had better physical and mental QOL. Women with less symptom distress of urinary incontinence and higher self-efficacy for urinary incontinence had better urinary incontinence-specific QOL. CONCLUSION: The health-related QOL of women with SUI is affected by many factors, including positive thinking, self-efficacy, and symptom distress. Healthcare professionals can provide multifaceted programs to improve the health-related QOL of women with SUI.

Motivational factors were more important than perceived risk or optimism for compliance to infection control measures in the early stage of the COVID-19 pandemic.

Compliance to infection control measures may be influenced both by the fear of negative consequences of a pandemic, but also by the expectation to be able to handle the pandemic's challenges. We performed a survey on a representative sample for Norway (N = 4,083) in the first weeks of the COVID-19 lock-down in March 2020. We had preregistered hypotheses to test the effect of optimism and perceived risk on compliance. Perceived risk had small effects on increasing compliance and on leading to more careful information gathering. The expected negative association between optimism and compliance was not supported, and there was instead a small positive association. We found a small effect that optimism was associated with seeing less risk from the pandemic and with a larger optimistic bias. Finally, an exploratory analysis showed that seeing the infection control measures as being effective in protecting others explained a substantial proportion of the variation in compliance. The study indicates that how we think about pandemic risk has complex and non-intuitive relationships with compliance. Our beliefs and motivations toward infection control measures appears to be important for compliance.

Dispositional optimism and business recovery during a pandemic.

A large literature at the crossroads of biology and cognitive psychology has shown that individuals hold generally positive expectations about future events. Despite this evidence, to date it remains unclear whether optimism has positive or negative implications for entrepreneurial activities. We examine this question in the context of the Covid-19 pandemic, which provides a unique way to study the role of optimism on the (in)ability of firms to overcome exogenous shocks. Using a large-scale longitudinal survey covering 1,632 UK firms, we find that entrepreneurs who score high on optimism were more likely to innovate and make organizational changes to their firms during the Covid-19 outbreak. Moreover, optimistic entrepreneurs experienced higher revenue growth during the pandemic. Collectively, our study sheds light on one of the psychological factors explaining why some firms can prosper and some others struggle in the wake of an external shock.

Dispositional optimism and all-cause mortality after esophageal cancer surgery: a nationwide population-based cohort study.

PURPOSE: To examine the association between dispositional optimism and all-cause mortality after esophageal cancer surgery and whether pathological tumor stage and the COVID-19 pandemic modified this association. METHODS: This nationwide, population-based prospective cohort study included 335 patients undergoing esophageal cancer surgery in Sweden between January 1, 2013, and December 31, 2019. Dispositional optimism was measured 1 year post-surgery using Life Orientation Test-Revised (LOT-R). A higher LOT-R sum score represents higher dispositional optimism. Mortality information was obtained from the Swedish Register of the Total Population. All patients were followed up until death or until December 31, 2020, whichever occurred first. Cox regression with adjustments for confounders was used. RESULTS: The median follow-up was 20.8 months, during which 125 (37.3%) patients died. Among the included 335 patients, 219 (65.4%) patients had tumor pathologically staged Tis-II, and 300 (89.6%) patients entered the cohort before the COVID-19 pandemic. Both tumor stage and the COVID-19 pandemic were effect modifiers. For each unit increase in LOT-R sum score, the risk of all-cause mortality decreased by 11% (HR 0.89, 95% CI 0.81 to 0.98) among patients with tumor staged Tis-II before the COVID-19 pandemic. This association was non-significant in patients with tumor staged III-IV (HR 0.99, 95% CI 0.92 to 1.07) and during the COVID-19 pandemic (HR 1.08, 95% CI 0.94 to 1.25). CONCLUSION: Assessing dispositional optimism may help predict postoperative survival, especially for patients with early and intermediate esophageal cancer. Increasing dispositional optimism might be a potential intervention target to improve survival after esophageal cancer surgery.

Positive attitudes towards COVID-19 vaccines: A cross-country analysis.

COVID-19 severely impacted world health and, as a consequence of the measures implemented to stop the spread of the virus, also irreversibly damaged the world economy. Research shows that receiving the COVID-19 vaccine is the most successful measure to combat the virus and could also address its indirect consequences. However, vaccine hesitancy is growing worldwide and the WHO names this hesitancy as one of the top ten threats to global health. This study investigates the trend in positive attitudes towards vaccines across ten countries since a positive attitude is important. Furthermore, we investigate those variables related to having a positive attitude, as these factors could potentially increase the uptake of vaccines. We derive our text corpus from vaccine-related tweets, harvested in real-time from Twitter. Using Natural Language Processing (NLP), we derive the sentiment and emotions contained in the tweets to construct daily time-series data. We analyse a panel dataset spanning both the Northern and Southern hemispheres from 1 February 2021 to 31 July 2021. To determine the relationship between several variables and the positive sentiment (attitude) towards vaccines, we run various models, including POLS, Panel Fixed Effects and Instrumental Variables estimations. Our results show that more information about vaccines' safety and the expected side effects are needed to increase positive attitudes towards vaccines. Additionally, government procurement and the vaccine rollout should improve. Accessibility to the vaccine should be a priority, and a collective effort should be made to increase positive messaging about the vaccine, especially on social media. The results of this study contribute to the understanding of the emotional challenges associated with vaccine uptake and inform policymakers, health workers, and stakeholders who communicate to the public during infectious disease outbreaks. Additionally, the global fight against COVID-19 might be lost if the attitude towards vaccines is not improved.

Relationship Between Optimism-Pessimism Levels of Mothers and Anxiety Levels of Children in Turkey During COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic affects all aspects of the population including children, elderly, and vulnerable people. The aim of this study is to examine, for the first time, the relationship optimism-pessimism levels of mothers and anxiety level of children in turkey during COVID-19 pandemic. SUBJECTS AND METHODS: Optimism-Pessimism Scale and Preschool Anxiety Scale were used to collect data from a representative sample of 33,362 mothers with children aged 3-6 years. RESULTS: Of the parents, 53% of them reported that their children were slightly anxious due to COVID-19 pandemic. Lower optimism and higher pessimism were significantly related with higher levels of children's anxiety including social, generalized, separation, and overall anxiety as well as obvious fear. Group comparison analysis indicated that very anxious children reported the highest level of different types of anxiety and fear compared to less anxious and not at all anxious children. CONCLUSION: These findings suggest that mental health of children has been adversely affected during the pandemic and this has important implications for designing and implementing interventions aimed at reducing anxiety levels of children and determining protective and risk factors associated with anxiety in the face of adversity.

The Unique Role of Hope and Optimism in the Relationship between Environmental Quality and Life Satisfaction during COVID-19 Pandemic.

COVID-19 in Malaysia has significantly affected the higher education system of the country and increased the level of distress among university students. Empirical evidence proposed that environment quality is associated with university students' life satisfaction during COVID-19. It was found that hope and optimism are linked with greater life satisfaction in general. Although past literature has reported the effects of hope and optimism on life satisfaction, there are limited studies examining the underlying mechanism among Malaysian private university students. Therefore, the current study offers the preliminary understanding of the intervening role of hope and optimism on the relationship between environmental quality and life satisfaction among private university students in Malaysia. A total of 133 private university students in Malaysia were recruited through homogenous convenience sampling. Partial least square structure equation modeling (SmartPLS) was used to analyze the mediation models. The results revealed that only hope mediated the relationship between environmental quality and life satisfaction, but not optimism. Hence, it is proposed that mental health providers should focus on providing hope-related interventions to university students in confronting COVID-19 challenges and ultimately improving life satisfaction.

The moderating effects of nostalgia on mood and optimism during the COVID-19 pandemic.

The initial waves of the coronavirus pandemic amplified feelings of depression, psychological fatigue and pessimism for the future. Past research suggests that nostalgia helps to repair negative moods by boosting current and future-oriented positive affect, thereby strengthening psychological resilience. Accordingly, the present study investigated whether nostalgia moderated the relationship between pandemic experience and individual differences in mood and optimism. Across two studies we assessed psychosocial self-report data from a total of 293 online participants (22-72 years old; mean age 38; 109 females, 184 males) during the first two waves of the pandemic. Participants completed comprehensive questionnaires that probed state and trait characteristics related to mood and memory, such as the Profile of Mood States, Nostalgia Inventory and State Optimism Measure. Our findings indicate that during the initial wave of coronavirus cases, higher levels of nostalgia buffered against deteriorating mood states associated with concern over the pandemic. Nostalgia also boosted optimism for participants experiencing negative mood, and optimism predicted subjective mood improvement one week later. This shielding effect of nostalgia on optimism was replicated during the second wave of coronavirus cases. The present findings support the role of nostalgia in promoting emotional homeostasis and resilience during periods of psychological distress.

Health Behaviours and the Sense of Optimism in Nursing Students in Poland, Spain and Slovakia during the COVID-19 Pandemic.

(1) The COVID-19 outbreak brought about several socio-economic changes and has had a negative impact on the mental health of people around the world. The aim of this study was to examine the correlation between health behaviours and dispositional optimism among nursing students in Poland, Spain and Slovakia during the COVID-19 pandemic. (2) The study was carried out in spring 2021 on a group of 756 nursing students in Poland (n = 390), Spain (n = 196) and Slovakia (n = 170). The diagnostic survey method was applied with the questionnaire technique, and the following standardised research tools were used: Life Orientation Test-Revised (LOT-R) and the Health Behaviour Inventory (IZZ). The survey was conducted in a mixed arrangement: in direct contact with the respondents in Poland and in Spain and online in Slovakia. (3) Significant differences were demonstrated in health behaviour preferences in students in Poland, Spain and Slovakia (F = 6.22; p < 0.002). The highest IZZ index was found in Spanish students (82.60 ± 13.65), while lower values were observed in Slovak (80.38 ± 13.74) and Polish (78.44 ± 13.47) students. The correlation between dispositional optimism and a positive attitude was the strongest in the Polish sample (r = 0.56; p < 0.001), at a high level in the Spanish sample (r = 0.53; p < 0.001) and at an average level in the Slovak sample (r = 0.48; p < 0.001). (4) 1. The study showed a moderating effect of the country of origin on the students' health behaviours. 2. Dispositional optimism is an important predictor of the students' health behaviours, regardless of the country of origin.

Feeling grateful to be optimistic: The influence of recalling special moments on feelings of gratitude and optimism during the COVID-19 pandemic.

In one experiment, we tested the influence of bringing to mind the memory of a special moment versus an ordinary moment from high school on gratitude and the relationship between gratitude and optimism. Participants were first asked to report how the current pandemic has affected their lives. After, participants were randomly assigned to either recalling a special moment from their high school years or recalling an ordinary event from the same life period. Participants then completed a battery of questionnaires assessing gratitude, optimism and some demographics. Results showed a positive influence of bringing to mind the memory of a special moment on gratitude. Gratitude was then positively related to optimism. Hence, the positive relationship between recalling a special event and optimism was mediated by gratitude. Our results showed that brief interventions might help individuals see a brighter future under the current difficult conditions of prolonged lockdowns.

2021: A Year of Hope and Heartbreak.

Optimism that the pandemic would be over was short lived.

Are People Optimistically Biased about the Risk of COVID-19 Infection? Lessons from the First Wave of the Pandemic in Europe.

Unrealistic optimism, the underestimation of one's risk of experiencing harm, has been investigated extensively to understand better and predict behavioural responses to health threats. Prior to the COVID-19 pandemic, a relative dearth of research existed in this domain regarding epidemics, which is surprising considering that this optimistic bias has been associated with a lack of engagement in protective behaviours critical in fighting twenty-first-century, emergent, infectious diseases. The current study addresses this gap in the literature by investigating whether people demonstrated optimism bias during the first wave of the COVID-19 pandemic in Europe, how this changed over time, and whether unrealistic optimism was negatively associated with protective measures. Taking advantage of a pre-existing international participative influenza surveillance network (n = 12,378), absolute and comparative unrealistic optimism were measured at three epidemic stages (pre-, early, peak), and across four countries-France, Italy, Switzerland and the United Kingdom. Despite differences in culture and health response, similar patterns were observed across all four countries. The prevalence of unrealistic optimism appears to be influenced by the particular epidemic context. Paradoxically, whereas absolute unrealistic optimism decreased over time, comparative unrealistic optimism increased, suggesting that whilst people became increasingly accurate in assessing their personal risk, they nonetheless overestimated that for others. Comparative unrealistic optimism was negatively associated with the adoption of protective behaviours, which is worrying, given that these preventive measures are critical in tackling the spread and health burden of COVID-19. It is hoped these findings will inspire further research into sociocognitive mechanisms involved in risk appraisal.
