Sleep quality and sleep duration are associated with charitable donations: Evidence from two population-based surveys

STUDY OBJECTIVES

Insufficient sleep alters emotional processing, leading to mood disturbances, reduced gratitude, and potentially the withdrawal of compassionate helping. Using data from two national surveys, we investigated whether sleep quality and sleep duration were associated with willingness to donate to local charities and places of worship.

METHODS

We conducted secondary analyses of two Gallup-administered studies that used random address-based sampling methodologies to approximate population-representative samples. BRS-5 included 1501 respondents and BRS-6 included 1336 respondents (independent samples). Each survey inquired about sleep quality and whether participants had donated in the last year to local organizations and places of worship. In addition, BRS-5 included questions about sleep duration.

RESULTS

In both studies, participants who had better sleep quality and better sleep durations were more likely to donate charitably to local organizations and places of worship (ORs of 1.07-1.45). Most associations remained significant when accounting for age, gender, and income.

CONCLUSION

Better sleep was associated with a greater likelihood to donate charitably. Experimental work is needed to determine if the relationship between sleep health and prosocial behaviors is uni- or bi-directional.

Trait emotional intelligence mediates the dispositional gratitude and subjective well-being in young adults

Gratitude has proved to be an enhancer of subjective well-being in previous studies. However, studies that linked the relation between emotional intelligence and its facets when interacting with gratitude, are still limited. In this sense, this study examined the mediating roles of emotional intelligence between gratitude and subjective well-being indicators, by introducing the general factor of emotional intelligence. The first approach to data analysis was to examine the descriptive statistics; the second approach consisted of an Exploratory Structural Equation Modelling, applying also a bifactor analysis. Data was collected from 406 Spanish students, through an online survey that includes the gratitude, trait meta mood scale, satisfaction with life and subjective happiness scale. The mean age of participants was 20.27 years (SD = 4.68), whereas 79.5% were females. The results provided preliminary evidence of the mediation role of the general factor of emotional intelligence between gratitude and subjective well-being, which provided a meaningful insight about the role of trait emotional intelligence. These findings suggested that gratitude promotes emotional intelligence, allowing to an increase in subjective well-being. Nonetheless, there is a need for further research to achieve a better understanding of the role of the emotional intelligence facets between gratitude and subjective well-being.

Lower perceived stress among physically active elite private university students with higher levels of gratitude

Elite private universities have high stress levels, particularly for underrepresented populations. While physical activity and gratitude can both reduce stress, independent effects from gratitude and interaction effects between physical activity and gratitude on stress are insufficiently explored. Our study investigated these effects among undergraduates at elite private universities. Undergraduates (n = 145) completed an online survey in Fall 2022. Moderate-high physical activity levels were reported by 96.19% of the sample. No significant interaction effect between physical activity and gratitude was seen nor a significant main effect of physical activity on perceived stress. A significant main effect of gratitude on perceived stress [F (2, 99) = 16.732, p < .001, ω2 = .253] was found with higher perceived stress among participants with low compared to moderate (p = .001) or high gratitude (p < .001). Gratitude exerted an independent, significant effect on perceived stress among elite university undergraduates and could be used as an additional healthy coping mechanism along with physical activity to combat stress.

Insomnia

Sleep significantly impacts health. Insomnia, characterized by difficulty with sleep onset, maintenance, and subsequent daytime symptoms, is increasingly prevalent and increases the risk of other medical comorbidities. The pathophysiology involves hyperarousal during non-REM sleep and altered sleep homeostasis. The 3P model explains the development and persistence of insomnia. Assessment is primarily clinical and based on appropriate history while distinguishing from other sleep disorders. "Somnomics" suggests a personalized approach to management. Cognitive behavioral therapy for insomnia is the first-line treatment in addition to other nonpharmacological strategies. Medications are a secondary option with weak supporting evidence.

The impact of gratitude interventions on patients with cardiovascular disease: a systematic review

Positive psychological factors play a pivotal role in improving cardiovascular outcomes. Gratitude interventions are among the most effective positive psychological interventions, with potential clinical applications in cardiology practice. To better understand the potential clinical effects of gratitude interventions in cardiovascular disease, four databases (Web of Science, Scopus, PubMed, and PsycArticles) were searched from 2005 to 2023 for relevant studies. Randomized controlled trials of gratitude interventions as the intervention and that reported physiological or psychosocial outcomes were eligible for inclusion. In total, 19 studies were identified, reporting results from 2951 participants from 19 to 71 years old from both healthy populations and those with clinical diagnoses. The studies showed that gratitude not only promotes mental health and adherence to healthy behaviors but also improves cardiovascular outcomes. Gratitude may have a positive impact on biomarkers of cardiovascular disease risk, especially asymptomatic heart failure, cardiovascular function, and autonomic nervous system activity.

How emotions induced by reading influence sleep quality in young and older adults

OBJECTIVES

This study examined whether emotions induced by reading before sleep influence sleep quality in young and older adults.

METHOD

Sixty older adults (64-75 years) and 60 young adults (18-35 years) were randomly assigned to three conditions: positive reading, neutral reading, and control. The reading groups read a short story at bedtime, whereas the control group kept its routine. Participants completed measures of affective states, subjective sleep parameters, and self-reported sleep quality related to emotions over 7 consecutive days.

RESULTS

Older adults reported much longer sleep latency and lower sleep efficiency than young adults. In both reading conditions, older adults reported reduced sleep latencies compared to the control group. In the positive reading condition, older adults reported an increased sleep duration compared to younger adults and the other conditions. Young and older adults in the positive condition showed better self-reported sleep quality than those in the neutral conditions, regardless of age.

CONCLUSIONS

Reading at bedtime appears to reduce older adults' time to fall asleep and increase their sleep duration. Positive emotions induced by reading short stories at bedtime seem to be a sleep-promoting factor that improves bedtime and wake time in young and older adults.

The effects of gratitude interventions: a systematic review and meta-analysis

INTRODUCTION

Gratitude has several implications. Over time, a logical relationship has been established between gratitude and well-being. In addition, researchers aimed to establish associations between gratitude and other factors of positive feelings using scientific methods. We conducted a systematic review and meta-analysis of interventions to develop gratitude and its benefits to human beings.

OBJECTIVE

This study aimed to evaluate and quantify the available scientific evidence on interventions to acquire knowledge on gratitude as a quantifiable causal factor of benefit to human beings.

METHODS

A systematic literature search was conducted to identify studies that investigated the effects of gratitude interventions. MEDLINE, Embase, and Central Cochrane databases were searched in addition to gray (Google Scholar) and manual search. Two authors independently evaluated the titles and abstracts, and selected the studies that met the inclusion criteria. The searches were conducted between January and July 2022.

RESULTS

Sixty-four randomized clinical trials were included. The meta-analysis demonstrated that patients who underwent gratitude interventions experienced greater feelings of gratitude, better mental health, and fewer symptoms of anxiety and depression. Moreover, they experienced other benefits such as a more positive mood and emotions.

CONCLUSION

The results demonstrate that acts of gratitude can be used as a therapeutic complement for treating anxiety and depression and can increase positive feelings and emotions in the general population. Prospero database registration: (www.crd.york.ac.uk/prospero) under the number CRD42021250799.

The Effects of Subjective Wellbeing and Self-Rated Health on Lifetime Risk of Cardiovascular Conditions in Women

Subjective wellbeing may predict future health conditions, and lower self-rated physical health (SRH) is associated with the presence of chronic conditions, such as cardiovascular disease (CVD). This study examines whether subjective wellbeing and SRH predict long-term CVD conditions for women using the Midlife in the United States study. The study cohort includes 1716 women participants who completed waves 1 (1995-1996), 2 (2004-2006), and 3 (2013-2014). Data on demographics, chronic conditions of diabetes and CVD, subjective wellbeing (life satisfaction, positive affect, and negative affect), and SRH were collected repeatedly at each wave. Multiple logistic regressions were conducted to test whether subjective wellbeing was associated with a lifetime CVD risk. Greater life satisfaction was significantly associated with a lower risk of CVD at 10 years (odds ratio (OR): 0.83; 95% confidence interval (CI): 0.74-0.95) and 19 years (OR: 0.83; 95% CI: 0.74-0.93), while positive and negative affects were not significantly associated. Additionally, better physical SRH significantly lowered odds of having cardiovascular conditions at both 10 years (OR: 0.79; 95% CI 0.68-0.92) and 19 years (OR 0.74; 95% CI: 0.64-0.86). Measures of life satisfaction and SRH can be used as additional CVD screening tools.

Gratitude and Life Satisfaction among Older Adults in Saudi Arabia: Social Support and Enjoyment of Life as Mediators

This cross-sectional study aimed to investigate the relationship between gratitude and life satisfaction, and the mediation role of social support and enjoyment of life among older individuals. The measures employed include the Gratitude, Resentment, and Appreciation test; the Enjoyment of Life scale; the Satisfaction with Life scale; and the Multidimensional Scale of Perceived Social Support. These were administered to a sample of 260 older individuals aged between 60 and 80. The main findings revealed a positive association between gratitude and life satisfaction, and social support was a partial mediator in this relationship. Although enjoyment of life was not a direct mediator in the relationship between gratitude and life satisfaction, the final model indicated a significant serial pathway from gratitude to social support and then through enjoyment of life to life satisfaction. In conclusion, enhancing gratitude, promoting the enjoyment of life, and social support to older individuals might increase their life satisfaction, which in turn might contribute to their successful aging.

The Role of Gratitude in a Positive Psychology Group Intervention Program Implemented for Undergraduate Engineering Students

Over the past decades, research on positive psychology for building strengths has proliferated. The present study aimed to explore the effect of gratitude in a 5-week positive psychology group program for undergraduate engineering students which included an intermediary 2-week gratitude intervention. In a mixed-design, 69 students from three engineering departments of the School of Pedagogical and Technological Education (ASPETE), assigned to the intervention (N = 34) and the control group (N = 35), with an average age of 21.52 years (SD = 4.63), were administered the Gratitude Questionnaire-six item form (GQ-6), the Modified Differential Emotions Scale (mDES), the Connor-Davidson Resilience Scale (CD-RISC), the Subjective Happiness Scale (SHS), and the Life Orientation Test-Revised (LOT-R). The condition experimental vs. control group was designated as the between-subjects factor, and time, that is, baseline vs. post intervention, was set as the within-subjects factor. Students who received the intervention reported significantly higher levels of gratitude. The increase in gratitude was due to the positive psychology group program. In addition, gratitude showed a significant effect on happiness and optimism, but failed to attain a significant impact on positive and negative emotions and resilience. Further research is needed to elucidate the effectiveness of positive psychology programs for undergraduate engineering students and the intervening cognitive processes.

Psychosocial Factors Associated With Accelerated GrimAge in Male U.S. Military Veterans

OBJECTIVE

Veterans are at high risk for health morbidities linked to premature mortality. Recently developed "epigenetic clock" algorithms, which compute intra-individual differences between biological and chronological aging, can help inform prediction of accelerated biological aging and mortality risk. To date, however, scarce research has examined potentially modifiable correlates of GrimAge, a novel epigenetic clock comprised of DNA methylation surrogates of plasma proteins and smoking pack-years associated with various morbidities and time-to-death. The objective of the study was to examine psychosocial correlates of this novel epigenetic clock.

DESIGN

Cross-sectional study.

SETTING

U.S. veteran population.

PARTICIPANTS

Participants were male, European American (EA), and derived from a nationally representative sample of U.S. veterans (N = 1,135, mean age = 63.3, standard deviation [SD] = 13.0).

MEASUREMENTS

We examined the prevalence of accelerated GrimAge and its association with a broad range of health, lifestyle, and psychosocial variables.

RESULTS

A total 18.3% of veterans had accelerated GrimAge (≥5 years greater GrimAge than chronological age; mean = 8.4 years acceleration, SD = 2.2). Fewer days of weekly physical exercise (relative variance explained [RVE] = 27%), history of lifetime substance use disorder (RVE = 21%), greater number of lifetime traumas (RVE = 19%), lower gratitude (RVE = 13%), reduced sleep quality (RVE = 7%), lower openness to experience (RVE = 7%), and unmarried/partnered status (RVE = 6%) were independently associated with increased odds of accelerated GrimAge. Increasing numbers of these risk factors were associated with greater odds of accelerated GrimAge, with greatest likelihood of acceleration for veterans with ≥3 risk factors (weighted 21.5%).

CONCLUSIONS

These results suggest that nearly 1-of-5 EA male U.S. veterans have accelerated GrimAge, and highlight a broad range of health, lifestyle, and psychosocial variables associated with accelerated GrimAge. Given that many of these factors are modifiable, these findings provide promising leads for risk stratification models of accelerated biological aging and precision medicine-based targets for interventions to mitigate risk for premature mortality in this population.

Exploring the relationship between gratitude and depression among older adults with chronic low back pain: a sequential mediation analysis

Introduction

Gratitude has been identified as a key factor in a number of positive health-related outcomes; however, the mechanisms whereby gratitude is associated with well-being among older adults with chronic pain are poorly understood. Using the Positive Psychological Well-Being Model as a theoretical framework, the objective of the present study was to examine the serial mediating effects of social support, stress, sleep, and tumor necrosis factor-alpha (TNF-α) on the relationship between gratitude and depressive symptoms.

Methods

A total sample of 60 community-dwelling older adults with chronic low back pain (cLBP) provided blood samples for high-sensitivity TNF-α and completed the Gratitude Questionnaire, Perceived Stress Scale, and the PROMIS Emotional Support, Sleep Disturbance, and Depression forms. Descriptive statistics, correlation analyses, and serial mediation analyses were performed.

Results

Gratitude was negatively associated with perceived stress, sleep disturbance, and depression, and was positively associated with social support. No significant association was observed between gratitude and TNF-α. After controlling for age and marital status, analyses revealed that perceived stress and sleep disturbance sequentially mediated the association between gratitude and depressive symptoms.

Conclusion

Perceived stress and sleep disturbance may be potential mechanistic pathways by which gratitude impacts negative well-being. Targeting gratitude as a protective resource may be a potential therapeutic tool to improve psychological and behavioral outcomes in older adults with cLBP.

Gratitude, affect balance, and stress buffering: A growth curve examination of cardiovascular responses to a laboratory stress task

Previous research has indicated that gratitude and affect-balance play key stress-buffering roles. However, to date there is limited research on the impact of gratitude and affect balance on cardiovascular recovery from acute psychological stress, and whether affect balance moderates the relationship between gratitude and cardiovascular reactions to acute psychological stress. In this study, 68 adults completed measures of state gratitude, positive and negative affect, and completed a laboratory-based cardiovascular stress-testing protocol. This incorporated a 20-minute acclimatization period, a 10-minute baseline, a 6-minute arithmetic stress task, and an 8-minute recovery period. Mixed-effects growth curve models were fit and the results indicated that state gratitude predicted lower systolic blood pressure responses throughout the stress-testing period. Affect balance was found to moderate the association between state gratitude and diastolic blood pressure responses to stress, amplifying the effects of state gratitude. These findings suggest that state gratitude has a unique stress-buffering effect on both reactions to and recovery from acute psychological stress.

Inpatient suicide in psychiatric settings: Evaluation of current prevention measures

The risk of suicide in psychiatric hospitals is 50 times higher than in the general population, despite patient safety being a priority for any hospital. However, to date, due to the complexity of assessing suicide risk, there has been no consensus on the suicide prevention measures that should be in place in hospitals. The aim of this work is: To provide an overview of the progress that has been made in the field of inpatient suicide prevention in recent years; discuss the problems that remain; and suggest potential future developments. As new clinical dimensions (notably anhedonia, psychological pain and hopelessness) develop, they should become new therapeutic targets. Team training (like the Gatekeeper Training Program) and the latest advances in suicide risk assessment (such as the Collaborative Assessment and Management of Suicidality) should be implemented in psychiatric wards. Suicide prevention plans (e.g., ASSIP, SAFE-T, etc.) represent easy-to-administer, low-cost interventions. The Mental Health Environment of Care Checklist has been proven effective to reduce suicide risk at hospitals. Furthermore, the types of psychotherapy recommended to reduce suicide risk are cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT). There are several pharmacological treatments for suicide risk, such as lithium and clozapine, which have been shown to be effective in the long term, as well as ketamine and esketamine, which are more effective in the short term. Following some encouraging recent results, buprenorphine may also be proposed to patients with a suicide risk. Triple chronotherapy rapidly improves depressive symptoms over 9 weeks. Regarding brain stimulation techniques, rTMS has proven to be effective in alleviating multiple dimensions of suicidality.

Boosting Student Wellbeing Despite a Pandemic: Positive Psychology Interventions and the Impact of Sleep in the United Arab Emirates

Positive psychology interventions hold great promise as schools around the world look to increase the wellbeing of young people. To reach this aim, a program was developed to generate positive emotions, as well as improve life satisfaction, mental toughness and perceptions of school kindness in 538 expatriate students in Dubai, United Arab Emirates. Starting in September 2019, the program included a range of positive psychology interventions such as gratitude, acts of kindness and mental contrasting as examples. Life satisfaction and mental toughness at mid-year were sustained or grew by the end of the year. Positive affect, emotional wellbeing and social wellbeing increased at post-intervention 1, compared to baseline. However, this improvement reverted to baseline levels at post-intervention 2, when data were collected during the COVID-19 pandemic. Only psychological wellbeing, negative affect, perceptions of control, and school kindness were increased at post-intervention 2. During the lockdown, students moved less, but slept and scrolled more. Those who extended their sleep duration reported greater wellbeing. Boosting wellbeing through the use of positive psychology interventions works – even in a pandemic – and extended sleep duration appears to be a driving factor for this observation.

Effects of Induced Optimism on Subjective States, Physical Activity, and Stress Reactivity

This study examined effects of experimentally-induced optimism on physical activity and stress reactivity with community volunteers. Using an intervention to induce short-term optimism, we conducted two harmonized randomized experiments, performed simultaneously at separate academic institutions. All participants were randomized to either the induced optimism intervention or to a neutral control activity using essay-writing tasks. Physical activity tasks (Study 1) and stress-related physiologic responses (Study 2) were assessed during lab visits. Essays were coded for intensity of optimism. A total of 324 participants (207 women, 117 men) completed Study 1, and 118 participants (67 women, 47 men, 4 other) completed Study 2. In both studies, the optimism intervention led to greater increases in short-term optimism and positive affect relative to the control group. Although the intervention had limited effects on physical activity and stress reactivity, more optimistic language in the essays predicted increased physical activity and decreased stress reactivity.

The impact of a gratitude intervention on mental well-being during COVID-19: A quasi-experimental study of university students

Previous research suggest that gratitude interventions are effective in improving mental well‐being, which might be beneficial to university students during the COVID‐19 pandemic. This quasi‐experimental study sought to investigate if a gratitude intervention will lead to higher mental well‐being of university students during the COVID‐19 pandemic. Participants (N = 47) mental well‐being was assessed before and after 10 weekly gratitude reflection journals and statistically compared with a control group (N = 40). An analysis of covariance (ANCOVA) was used to analyze the data. The treatment group showed significantly higher well‐being after the gratitude intervention compared with the control group (Cohen's d = 0.74). The treatment group significantly increased (Cohen's d = 0.35) and the control group significantly decreased (Cohen's d = −0.41). Gratitude interventions may be effective in improving the mental well‐being of university students even during a crisis such as the COVID‐19 pandemic. Gratitude interventions seem suitable for improving mental well‐being for temporary mental challenges of university students such as a pandemic or other forms of crisis.

The Frailty Puzzle: Searching for Immortality or for Knowledge Survival?

What is the value of assessing the biological age and frailty and predicting residual lifespan and health status? The benefit is obvious if we have means to alter the pace of aging and the development of frailty. So far, limited but increasing examples of interventions altering the predicted status indicate that, at least in some cases, this is possible through interventions spanning from the economic-social through drug treatments. Thus, why searching for biological markers, when some clinical and socio-economic indicators do already provide sufficiently accurate predictions? Indeed, the search of frailty biomarkers and of their biological clocks helps to build up a mechanistic frame that may orientate the design of interventions and the time window of their efficacy. Among the candidate biomarkers identified, several studies converge to indicate epigenetic clocks as a promising sensitive biomarker of the aging process. Moreover, it will help to establish the relationship between personal aging and health trajectories and to individuate the check points beyond which biological changes are irreversible.

Does Gratitude Promote Resilience During a Pandemic? An Examination of Mental Health and Positivity at the Onset of COVID-19

Researchers have emphasized the detrimental effects of COVID-19 on mental health, but less attention has been given to personal strengths promoting resilience during the pandemic. One strength might be gratitude, which supports wellbeing amidst adversity. A two-wave examination of 201 college students revealed anxiety symptom severity increased to a lesser extent from pre-COVID (January-March 2020) to onset-COVID (April 2020) among those who reported greater pre-COVID gratitude. A similar trend appeared for depression symptom severity. Gratitude was also correlated with less negative changes in outlook, greater positive changes in outlook, and endorsement of positive experiences resulting from COVID-19. Thematic analysis showed "strengthened interpersonal connections" and "more time" were the most commonly reported positive experiences. Overall findings suggest gratitude lessened mental health difficulties and fostered positivity at the onset of the pandemic, but more research is needed to determine whether gratitude and other strengths promote resilience as COVID-19 continues.

Sleep and stress in times of the COVID-19 pandemic: The role of personal resources

There is still little research on the association between COVID-19-related stress and insufficient sleep. As distress is assumed to be high in these times, the role of personal resources becomes more important. The current study aimed to investigate the predictive role of COVID-19-related stress, positive affect, and self-care behavior for subjective sleep quality and sleep change measures since the outbreak of COVID-19 in Germany. A sample of 991 adults (M = 34.11 years; SD = 12.99) answered questionnaires during the first lockdown period in Germany and afterward (between April 1 and June 5, 2020). A higher stress level predicted lower sleep quality and more negative changes in overall sleep and pre-sleep arousal. Higher levels of positive affect and self-care predicted higher sleep quality and more positive changes in sleep. Analyses showed a moderation of positive affect on the association between stress and change in pre-sleep arousal. The improvement in personal resources, especially positive affect, in times of high stress seems relevant to overcome sleep problems. Future research should include objective measurements of sleep and longitudinal designs to uncover causal directions of effects.

Nursing Students' Experiences of Gratitude Journaling during the COVID-19 Pandemic

Gratitude journaling has been used to improve grateful disposition. However, there is only limited data available on its application experience. This study aimed to: (1) explore the experiences of nursing students who have participated in gratitude journaling; and (2) assess students’ views of gratitude journaling as a nursing intervention. This study implemented an eight-week program of gratitude journaling with fourth-year nursing students who took a mental health psychiatric nursing course at a South Korean university. Following the eight weeks, students reflected on their gratitude journaling experience in a reflective essay. Using content analysis, 53 essays were analyzed. Five categories were identified from the reflective essay, as follows: “A new beginning”, “The engine that motivates continued participation: gratitude sharing”, “The process driving change”, “Changes brought about by gratitude”, and “Self-reflection”. Based on this experience, nursing students believed that it is important to promote steady participation when administering gratitude journaling as a nursing intervention. The study findings suggest that the gratitude journaling not only helped with nursing students’ perspective, emotional, and behavioral aspects and stress management, but also provided an opportunity to advance a step further based on self-reflection.

Gratitude Questionnaire (GQ-6)-Exploring Psychometric Properties in India

Due to culture-based differences in conceptualization, expression, and gratitude experience, the GQ-6 scale has been validated in different countries. The present study examines the adaptability of the Gratitude Questionnaire (GQ-6) scale in India. Two studies are conducted to evaluate the psychometric properties of GQ-6 for Indian college students. The first study explores factorial validity, reliability, and measurement invariance of the scale. Appropriate factor loading in exploratory factor analysis and model fit indices in confirmatory factor analysis (CFA) provides empirical evidence of the scale's factorial validity. The second study investigates the convergent and criterion validity of the scale. A positive correlation with positive affect (PANAS scale) and life satisfaction (Wheel of Life Scale) and a negative association with negative affect (PANAS scale) establish criterion validity of GQ-6. The results conclude adequate suitability of the GQ-6 scale for Indian college students.

Multimodule Web-Based COVID-19 Anxiety and Stress Resilience Training (COAST): Single-Cohort Feasibility Study With First Responders

BACKGROUND

Since the emergence of COVID-19, health care workers and first responders have been at a high risk for mental health symptoms owing to their exposure to the virus and increased work stress during the pandemic. Although interventions exist to address mental health issues following exposure to disasters, emergencies, and humanitarian crises, considerably less is known about web-based unguided interventions to help mitigate the negative impacts of such events. Additionally, in contexts in which emergencies reduce access to in-person care, remote forms of support are critical, yet there are limited studies on the use of such interventions. Evidence-based, easy-to-use, scalable interventions are direly needed for this population.

OBJECTIVE

This study aimed to develop and test the feasibility of an unguided electronic mental health program, COVID-19 Anxiety and Stress Resilience Training (COAST), tailored to first responders and health care personnel, based on scientific evidence and empirically based techniques.

METHODS

We developed COVID-19-specific training modules focusing on several domains that are previously reported as key to resilience and stress recovery: self-efficacy, mindfulness, sleep quality, and positive thinking. The program was made available to 702 first responders between May and August 2020, during the COVID-19 pandemic. Sociodemographic, work-, and COVID-19-related information was collected, and psychometric questionnaires were completed. We examined user acceptance and user activity, including module choice and participant feedback.

RESULTS

In total, 52 of 702 (7%) first responders to whom we reached out used the program at least once. COAST use was independent of age, sex, or baseline levels of self-efficacy, mindful awareness, sleep quality, and positive thinking (for all, P>.39). First responders who had tested positive and those who had been quarantined were more likely to engage in the program. A click count analysis per module showed that participants used the self-efficacy and mindfulness modules most often, with 382 and 122 clicks, respectively, over 15 weeks. Overall, first responders expressed satisfaction with the program.

CONCLUSIONS

Engagement of first responders in the multimodule web-based COAST program was feasible and the first responder cohort expressed overall satisfaction with the program. Those in more difficult circumstances, including those in quarantine and those who tested positive, may be more likely to engage in such programs. Further controlled studies could pave the way for efficacy studies and the development of additional modules, including just-in-time interventions or blended interventions combining individual use of an unguided self-help intervention, such as COAST, with subsequent individual psychotherapy for those who continue to experience stress and psychological symptoms.

Enhanced academic motivation in university students following a 2-week online gratitude journal intervention

Background

Past studies have associated gratitude interventions with a host of positive outcomes. However, there is a dearth of research regarding the impact such interventions have on the academic motivation of university students, thought to be a primary determinant of academic achievement and overall satisfaction with school activities. Here, we examined the effects of a 2-week online gratitude journal intervention on the academic motivation of university students.

Methods

Eighty-four students were randomly assigned to either an active manipulation group (gratitude group) or a neutral control group. In the first 6 days of each week, participants in the gratitude group were asked to log in to the online system once a day and list up to five things they had felt grateful for. They were also requested to evaluate various aspects of their daily lives. Participants in the control group were only requested to perform the daily self-evaluations. Academic motivation was assessed using the Academic Motivation Scale (AMS), which conceptualizes motivation in academic settings as being composed by three different components, i.e., intrinsic motivation, extrinsic motivation and amotivation, the latter being associated with the perceived lack of contingency between actions and outcomes. Responses were collected 5 times: before group assignment (baseline), 1 week after the start of the intervention, immediately after the intervention, and at two follow-ups, 1 and 3 months after the intervention.

Results

Analysis using a self-determination index derived from the AMS components showed that participants who regularly engaged with the gratitude journal task displayed significant enhancements in academic motivation. Additional analysis revealed that the enhancements were driven by decreases in the levels of amotivation. Furthermore, follow-up data showed that there were no signs that such enhancements had receded 3 months after the end of the intervention. Improvements in academic motivation were not observed among participants in the control group.

Conclusions

The current results provide evidence that gratitude interventions can positively impact the academic motivation of university students. More broadly, they show that the effects extend well beyond the realm of typically assessed measures of individual well-being, and can effectively regulate a fundamental component of goal-directed behavior such as motivation.

Listening to motivational music during warming-up attenuates the negative effects of partial sleep deprivation on cognitive and short-term maximal performance: Effect of time of day

This study assessed the effect of time of day (TOD) and listening to music during warm-up on cognitive and physical performances after partial sleep deprivation (PSD) and normal sleep nights (NSN). In a randomized order, twelve male physical education students [mean (SD) age 20.3 ± 2.0 y; BMI 22.90 ± 3.57 kg/m²)] completed a 30-s Wingate test (i.e., mean (MP) and peak powers (PP)), simple (SRT) and choice reaction times (CRT), a mental rotation test (MRT) and a selective attention test. Measurements were performed at 07:00 h and 17:00 h after a NSN and PSD with and without music, with an in-between recovery period of ≥72. Salivary cortisol was measured before and immediately after the Wingate test. Compared to NSN, the results showed that PSD decreased PP (p < .05, d = 0.86) and MP (p < .01, d = 0.86) in the afternoon. However, compared to NSN, listening to music during the warm up after PSD enhanced PP (p < .01, d = 1.40) and MP (p < .05, d = 0.82) in the morning and PP (p < .05, d = 0.78) in the afternoon. Moreover, listening to music lowered post-exercise cortisol in the morning both after NSN (p < .05, d = 0.79) and PSD (p < .05, d = 0.11). After PSD, music reduced the negative mood states (p < .01, d = 0.94), the SRT (p < .05, d = 0.79) and the CRT (p < .05, d = 0.49) in the afternoon. These findings suggest that listening to music during warm-up (i) enhances cognitive and short-term all out performances after NSN and PSD and (ii) partially counteracts sleep-loss-induced degradation of physical and cognitive performances at both TODs.

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Gratitude, social support and cardiovascular reactivity to acute psychological stress

The pathways linking gratitude to cardiovascular reactivity (CVR) to acute stress are not fully understood. We examine whether this association is mediated by social support. Healthy adults (N = 178) completed measures of trait gratitude and perceived social support and participated in a standardised mental arithmetic and speech stress testing protocol. Their CVR (i.e., systolic and diastolic blood pressure [SBP, DBP], heart rate [HR], cardiac output [CO] and total peripheral resistance [TPR]) were monitored throughout. Gratitude was positively associated with SBP, DBP and TPR reactivity, with those reporting higher gratitude showing higher CVR. Social support was positively associated with TPR to the maths task. The association between gratitude and TPR was mediated by social support but this was only evident in response to the maths task and not the speech task. These novel findings suggest that CVR may be a potential mechanism underlying the gratitude-physical health link.

Associations between daily affect and sleep vary by sleep assessment type: What can ambulatory EEG add to the picture?

OBJECTIVE/BACKGROUND

Disrupted sleep can be a cause and a consequence of affective experiences. However, daily longitudinal studies show sleep assessed via sleep diaries is more consistently associated with positive and negative affect than sleep assessed via actigraphy. The objective of the study was to test whether sleep parameters derived from ambulatory electroencephalography (EEG) in a naturalistic setting were associated with day-to-day changes in affect.

PARTICIPANTS/METHOD

Eighty adults (mean age = 32.65 years, 63% female) completed 7 days of affect and sleep assessments. We examined bidirectional associations between morning positive affect and negative affect with sleep assessed via diary, actigraphy, and ambulatory EEG.

RESULTS

Mornings with lower positive affect than average were associated with higher diary- and actigraphy-determined sleep efficiency that night. Mornings with higher negative affect than average were associated with longer actigraphy-determined total sleep time that night. Nights with longer diary-determined total sleep time, greater sleep efficiency, and shorter sleep onset latency than average were associated with higher next-morning positive affect, and nights with lower diary-determined wake-after-sleep-onset were associated with lower next-morning negative affect. EEG-determined sleep and affect results were generally null in both directions: only higher morning negative affect was associated with longer rapid eye movement (REM) sleep that night.

CONCLUSIONS

Self-reported sleep and affect may occur in a bidirectional fashion for some sleep parameters. EEG-determined sleep and affect associations were inconsistent but may still be important to assess in future studies to holistically capture sleep. Single-channel EEG represents a novel, ecologically valid tool that may provide information beyond diaries and actigraphy.

A pilot randomized controlled trial of a gratitude intervention for adolescents with Type 1 diabetes

AIM

Cost-effective psychosocial interventions that can feasibly be implemented into busy clinical settings are needed to improve psychological and physical health outcomes in adolescents with Type 1 diabetes. We examined the efficacy of a gratitude journalling intervention to improve psychological well-being and glycaemic control in adolescents aged 10-16 years with Type 1 diabetes.

METHODS

Eighty adolescents were randomized to the 8-week gratitude intervention (N = 40) or standard care (N = 40). Self-reported measures of stress, quality of life, self-care, depression and gratitude were assessed at baseline and 8 weeks after baseline. Glycaemic control (HbA_1c ) was assessed at baseline and 12 weeks after baseline. A per-protocol analysis was conducted with the adolescents who completed all questionnaires (N = 60). Analysis of covariance (ANCOVA) was used to examine differences between treatment arms at follow-up adjusting for baseline scores.

RESULTS

There was no evidence of any between-group differences in the psychological or behavioural measures at follow-up (all P-values > 0.05). Glycaemic control slightly increased in the control group while remaining stable in the gratitude group, with a between-group difference of 6.1 mmol/mol [95% confidence interval (CI) -2.6 to 14.7; 0.6%, 95% CI -0.2 to 1.3] at 12 weeks after baseline. After adjusting for baseline HbA_1c , this between-group difference was significant (P = 0.048).

CONCLUSIONS

This is the first randomized trial of a gratitude journalling intervention for adolescents with Type 1 diabetes. Gratitude journalling interventions represent a clinically usable approach. If and how it helps to stabilise glycaemic control in adolescents with Type 1 diabetes remains to be confirmed in future research.

A systematic review of gratitude interventions: Effects on physical health and health behaviors

OBJECTIVE

Gratitude interventions are easy-to-deliver, offering promise for use in clinical-care. Although gratitude interventions have consistently shown benefits to psychological wellbeing, the effects on physical health outcomes are mixed. This systematic review aims to synthesize gratitude intervention studies which assessed physical health and health behavior outcomes, as well as evaluate study quality, comment on their efficacy, and provide directions for future research.

METHODS

Relevant studies were identified through searches conducted in PsycINFO, MedLine, Embase and Cochrane Library databases, up until August 2019. Only studies that evaluated a gratitude intervention, randomly assigned participants to gratitude and control conditions, and assessed objective and subjective measures of physical health and health behaviors were included. The Revised Cochrane risk-of-bias (RoB2) tool was used to assess risk of bias.

RESULTS

Of the 1433 articles found, 19 were included in the review. Subjective sleep quality was improved in 5/8 studies. Improvements in blood pressure, glycemic control, asthma control and eating behavior were understudied yet demonstrated improvements (all 1/1). Other outcome categories remain understudied and mixed, such as inflammation markers (1/2) and self-reported physical symptoms (2/8). The majority of studies showed some risk of bias concerns.

CONCLUSIONS

Although it was suggested gratitude interventions may improve subjective sleep quality, more research is still needed to make firm conclusions on the efficacy of gratitude interventions on improving health outcomes. Further research focusing on gratitude's link with sleep and causal mechanisms is needed, especially in patient populations where more 'clinically-usable' psychosocial interventions are urgently needed.

A Structural Equation Model of Gratitude, Self-efficacy, and Medication Adherence in Patients With Stage B Heart Failure

BACKGROUND

Consistent self-care slows the progression of heart failure (HF). Gratitude, the practice of appreciating the positive aspects of life, may influence self-efficacy, which in turn is known to improve self-care. However, little is known about the relationships among gratitude, self-efficacy, and medication adherence in HF.

OBJECTIVE

The aim of this study was to test a model to determine if self-efficacy mediates the relationship between gratitude and medication adherence in asymptomatic patients with HF.

METHOD

This is a secondary analysis of data from a prospective observational study. Data were analyzed using a structural equation model to examine associations between gratitude, cardiac-specific self-efficacy, and medication adherence in 153 patients with HF. Gratitude, self-efficacy, and medication adherence were assessed using the Gratitude Questionnaire-6, Cardiac Self-efficacy Scale-Maintain Function Subscale, and the Morisky Medication Adherence Scale, respectively.

RESULTS

Patient mean (SD) age was 66 (11) years, and 95% of the participants were men. Patients were primarily white (79%), black (12%), or Asian (6%). Gratitude exerted an indirect effect on medication adherence through self-efficacy (b = 0.16; P < .05). Gratitude was positively related to self-efficacy (b = 0.50; P < .05), and self-efficacy was positively related to medication adherence (b = 0.31; P < .05). The model fit was acceptable (comparative fit index = 0.92, Tucker-Lewis index = 0.90, root-mean-square error of approximation = 0.08).

CONCLUSION

In this study, we found evidence that self-efficacy was a mechanism through which gratitude was associated with medication adherence in asymptomatic patients with HF, suggesting a way to improve self-care nonpharmacologically. Future work will examine whether gratitude intervention results in improved self-care.

Gratitude diary for the management of suicidal inpatients: A randomized controlled trial

BACKGROUND

The management of suicidal crisis remains a major issue for clinicians, driving the development of new strategies.

METHODS

We conducted a randomized controlled trial based on a 7-day add-on positive psychology program: gratitude diary (intervention) versus food diary (control) in adults hospitalized for current suicidal ideation or a suicide attempt. The primary effectiveness outcome was between-group differences for mean change of current psychological pain, between the beginning and the end of the 7-day intervention. We measured between-group differences for mean change of suicidal ideation, hopelessness and optimism, and depression and anxiety between inclusion and after the completion of the 7-day intervention. We compared mean change of current psychological pain, suicidal ideation, and hopelessness and optimism between immediate pre and post daily journal completion.

RESULTS

Two hundred and one participants were enrolled and randomized. Between pretherapy and posttherapy: There were no significant between-group differences for mean change of severity and intensity of suicidal ideation and current hopelessness. Between-group difference for mean change of current psychological pain was trending (P = 0.05). Mean change of depression, anxiety, and optimism was significantly higher in the intervention than in the control group. Between immediate pre and post daily journal completion: Between-group differences favored gratitude (vs. food) diary for all outcomes (psychological pain, suicidal ideation, and hopelessness and optimism; P < 10^-3 ). Participants found the intervention to be more useful than the food diary.

CONCLUSIONS

Through gratitude diary appears a very straightforward intervention that could be developed as an adjunctive strategy for suicidal patients.

Dispositional Gratitude Moderates the Association between Socioeconomic Status and Interleukin-6

Socioeconomic disparities in health are prevalent and growing in importance as a concern among academics, policymakers, and the general public. However, psychological resources that can narrow such disparities have not been well-examined. The current study examined the moderating role of dispositional gratitude in the relationship between socioeconomic status (SES) and inflammation risk as an index of health. Participants consisted of 1,054 midlife adults from the biomarker project of the Midlife in the United States. Inflammation risk was measured by interleukin-6 biomarker and SES was operationalized by education attainment and income. We found that dispositional gratitude significantly moderated the relationships between SES and interleukin-6. Among individuals with low dispositional gratitude, higher SES was significantly associated with lower levels of interleukin-6. However, the association between SES and interleukin-6 was not significant among individuals with high dispositional gratitude. More importantly, the findings remained robust after controlling for demographic characteristics, health status, health behaviours, and personality traits. Our findings suggest that gratitude may serve as an important psychological resource in attenuating health-related risk from socioeconomic stressors.

Sleep duration, health status, and subjective well-being: a population-based study

OBJECTIVE

To evaluate, in a population-based approach, the association of extreme sleep duration with sociodemographic factors, health, and well-being.

METHODS

We analyzed the data from the 2014/2015 Health Survey in the city of Campinas, State of São Paulo, Brazil (ISACamp), performed with 1,969 individuals (≥ 20 years old). Associations between the independent variable and short (≤ 6 hours) and long (≥ 9 hours) sleep were determined using the Rao-Scott chi-square test. The analyses were adjusted with multinomial logistic regression models.

RESULTS

Men, individuals aged 40 to 59, those with higher schooling, those who have one (OR = 1.47, 95%CI 1.02–2.12), two (OR = 1.73, 95%CI 1.07–2.80), or three or more (OR = 1.62, 95%CI 1.16–2.28) chronic diseases, and those with three or more health problems (OR = 1.96, 95%CI 1.22–3.17) were more likely to have a short sleep. The chance of long sleep was higher in widowers and lower in those who have more years of schooling, with higher income, worked, lived with more residents at home, and reported three or more diseases (OR = 0.68, 95%CI 0.48–0.97) and health problems. The chance of either short (OR = 2.41, 95%CI 1.51–3.87) or long sleep (OR = 2.07, 95%CI 1.23–3.48) was higher in unhappy individuals.

CONCLUSIONS

These findings highlight the higher chance of short sleep duration among men, among persons in productive age, and among those with a higher level of schooling in a Brazilian city. The association of short sleep with comorbidities and the association of happiness with extremes of sleep duration were also important results to understand the relation of sleep duration with health and well-being.

The Cultivation of Pure Altruism via Gratitude: A Functional MRI Study of Change with Gratitude Practice

Gratitude is an emotion and a trait linked to well-being and better health, and welcoming benefits to oneself is instrumentally valuable. However, theoretical and empirical work highlights that gratitude is more fully understood as an intrinsically valuable moral emotion. To understand the role of neural reward systems in the association between gratitude and altruistic motivations we tested two hypotheses: First, whether self-reported propensity toward gratitude relates to fMRI-derived indicators of "pure altruism," operationalized as the neural valuation of passive, private transfers to a charity versus to oneself. In young adult female participants, self-reported gratitude and altruism were associated with "neural pure altruism" in ventromedial prefrontal cortex (VMPFC) and nucleus accumbens. Second, whether neural pure altruism can be increased through practicing gratitude. In a double-blind study, we randomly assigned participants to either a gratitude-journal or active-neutral control journal group for 3 weeks. Relative to pre-test levels, gratitude journaling increased the neural pure altruism response in the VMPFC. We posit that as a context-dependent value-sensitive cortical region, the VMPFC supports change with gratitude practice, a change that is larger for benefits to others versus oneself.

Gratitude and Drug Misuse: Role of Coping as Mediator

BACKGROUND

Positive emotions, such as gratitude has been found to be beneficial to both physical and mental well-being but so far, drug misuse research has yet to identify important emotive predictors related to drug use.

OBJECTIVES

This study aimed to examine the relationship between gratitude and drug use among a group of drug misusers. It was hypothesized that greater dispositional gratitude was associated with lesser drug use through greater use of adaptive coping methods and lesser use of maladaptive coping methods.

METHODS

This study utilized a cross-sectional design to examine the relationship between gratitude, coping, and drug use among a sample of drug misusers (N = 105) at a drug rehabilitation center. Participants completed the gratitude questionnaire (GQ-6), the joy subscale of the Dispositional Positive Emotion Scale (DPES), the Brief COPE, and a questionnaire on their drug use. Data were collected in 2015.

RESULTS

Mediation analysis supported the hypothesis and found that adaptive coping mediated the relationship between gratitude and drug use. However, mediation was not found for maladaptive coping. Additional analysis found that adaptive coping as a mediator was not found for joy.

CONCLUSION

Results suggested that gratitude has utility in reducing drug use through the use of more adaptive coping strategies and this relationship was not simply due to positive affect. Interventions targeting drug use behavior could consider introducing gratitude to increase adaptive coping abilities to reduce drug use.

The Association Between Body Mass Index and Sleep in a Predominantly Hispanic College Population

An association between inadequate sleep and body mass index (BMI) has been demonstrated in previous studies, but there is a relative paucity of data from Latino/Hispanic populations. In the present study, 750 college students, 93% of whom were Hispanic, completed an online survey that included standardized measures of sleep quantity, sleep quality, and insomnia. BMI was significantly higher in those who had inadequate sleep quantity, in those with poor sleep quality, and in those who experienced insomnia. Our results extend previous research, demonstrating an association between BMI and three measures of sleep in a predominantly Hispanic college student sample.

Gratitude mediates the effect of emotional intelligence on subjective well-being: A structural equation modeling analysis

This study investigated the relationship among emotional intelligence, gratitude, and subjective well-being in a sample of university students. A total of 365 undergraduates completed the emotional intelligence scale, the gratitude questionnaire, and the subjective well-being measures. The results of the structural equation model showed that emotional intelligence is positively associated with gratitude and subjective well-being, that gratitude is positively associated with subjective well-being, and that gratitude partially mediates the positive relationship between emotional intelligence and subjective well-being. Bootstrap test results also revealed that emotional intelligence has a significant indirect effect on subjective well-being through gratitude.
