Battling the Modern Behavioral Epidemic of Loneliness: Suggestions for Research and Interventions

A large sample cross-sectional study on mental health challenges among adolescents and young adults during the COVID-19 pandemic at-risk group for loneliness and hopelessness during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic has posed unprecedented challenges for societies. Emerging data have indicated that the younger population are the most vulnerable group to the development of mental health problems during this pandemic. The present study aimed to examine the effects of the changes in health behaviors on mental health problems to identify an at-risk group among adolescents and young adults.

METHODS

In the present cross-sectional study, secondary school students (N = 2556) ages 15-21 years participated in Hungary. A self-report questionnaire was developed to measure the changes in health behaviors. Mental health problems were measured by the Beck Hopelessness Scale and the 20-item UCLA Loneliness Scale.

RESULTS

A significant proportion of the students showed moderate/severe hopelessness or high loneliness which were more pronounced among adolescent females. An at-risk group was identified among adolescents and young adults. Students who have a lower number of friends, spend less time in front of a screen, and feel lonely often/very often are more likely to have moderate/severe hopelessness with high loneliness.

LIMITATIONS

All data were collected online, and students completed the questionnaires voluntarily. Cross-sectional, non-preregistered study.

CONCLUSIONS

Loneliness and hopelessness were prevalent in the young population during the COVID-19 pandemic. The at-risk group of adolescents characterized by moderate/severe hopelessness with high loneliness highlights the need for follow-up mental health to avoid future poor mental and physical health. It is also recommended to develop effective interventions targeted to gender and age, with the promotion of resiliencies and buffers against vulnerabilities of negative life events.

The impact of loneliness and social adaptation on depressive symptoms: Behavioral and brain measures evidence from a brain health perspective

Introduction

Early detection of depression is a cost-effective way to prevent adverse outcomes on brain physiology, cognition, and health. Here we propose that loneliness and social adaptation are key factors that can anticipate depressive symptoms.

Methods

We analyzed data from two separate samples to evaluate the associations between loneliness, social adaptation, depressive symptoms, and their neural correlates.

Results

For both samples, hierarchical regression models on self-reported data showed that loneliness and social adaptation have negative and positive effects on depressive symptoms. Moreover, social adaptation reduces the impact of loneliness on depressive symptoms. Structural connectivity analysis showed that depressive symptoms, loneliness, and social adaptation share a common neural substrate. Furthermore, functional connectivity analysis demonstrated that only social adaptation was associated with connectivity in parietal areas.

Discussion

Altogether, our results suggest that loneliness is a strong risk factor for depressive symptoms while social adaptation acts as a buffer against the ill effects of loneliness. At the neuroanatomical level, loneliness and depression may affect the integrity of white matter structures known to be associated to emotion dysregulation and cognitive impairment. On the other hand, socio-adaptive processes may protect against the harmful effects of loneliness and depression. Structural and functional correlates of social adaptation could indicate a protective role through long and short-term effects, respectively. These findings may aid approaches to preserve brain health via social participation and adaptive social behavior.

The Mediatory Role of the Boredom and Loneliness Dimensions in the Development of Problematic Internet Use

In recent years, there has been a gradual digitalization of our society, resulting in intensified technology use for daily life activities, including the emergence of problematic Internet use (PIU). Few studies specifically addressed the boredom and loneliness dimensions in mediating the association between depression, anxiety, and stress levels and the onset of PIU. A nationwide population-based cross-sectional case-control study was carried out by recruiting a sample of Italian young people (aged 18-35). Only 1643 participants were selected for the analyses based on the age and the presence versus absence of PIU. Participants were mainly females (68.7%), with a mean age of 21.8 (SD = 1.7). Non-PIU individuals had significantly stable relationships (p = 0.012), siblings (p = 0.044) and lived with their family (p = 0.010), compared to PIU. PIU individuals displayed significantly higher depression, anxiety, and stress, as well as higher loneliness and boredom levels (all p < 0.001), compared to non-PIU. Depressive symptomatology predicted PIU and that their interaction is positively double mediated by boredom and loneliness (ß = 0.3829 (0.0245), 95%CI = 0.3349-0.4309). Our findings suggested that boredom and loneliness dimensions could act as mediators in the association between depressive symptomatology and the likelihood of PIU onset and maintenance.

With You Until the End of the Age? A Longitudinal Study of Changes in Religiosity and Loneliness in Later Life

With few exceptions, a vast literature on religion and well-being in later life has largely ignored outcomes of loneliness. The current study considers how changes in religiosity and formal religious participation over time associate with loneliness, and whether there are age differences in how this process unfold. Using data from the first two waves (2005-2006, 2010-2011) of the National Social Life, Health, and Aging Project (NSHAP) from the United States, results suggest that consistent religious attendance was associated with lower loneliness, while decreases in attendance were associated with higher loneliness. The association between stable high religious attendance and loneliness was stronger for older cohorts of older adults (65-74, and 75+ years of age). We found no such patterns for religious integration in daily life. We discuss the implications for church communities and family and friends of older adults and provide insights for addressing loneliness as a public health problem.

Short- and Medium-Term Effects of Ageism on Loneliness Experienced During the COVID-19 Pandemic

Loneliness, common in old age, may be partially attributed to ageism. The present study explored the short- and medium-term effect of ageism on loneliness experienced during the COVID-19 pandemic using prospective data derived from the Israeli sample of the Survey of Health, Aging and Retirement in Europe (SHARE) (N = 553). Ageism was measured before the COVID-19 outbreak and loneliness in the summer of 2020 and 2021 using a direct single question. We also tested for age differences in this association. In both the 2020 and 2021 models, ageism was related to increased loneliness. This association remained significant after adjusting for a host of demographic, health, and social variables. In the 2020 model, we also found that the positive association between ageism and loneliness was significant only in people aged 70+. We discussed the results with reference to the COVID-19 pandemic, which drew attention to two global social phenomena: loneliness and ageism.

Social Isolation Causes Cortical and Trabecular Bone Loss in Adult Male, but not Female, C57BL/6J Mice

Social isolation is a potent form of psychosocial stress and is a growing public health concern, particularly among older adults. Even prior to the onset of the COVID-19 pandemic, which has significantly increased the prevalence of isolation and loneliness, researchers have been concerned about a rising "epidemic" of loneliness. Isolation is associated with an increased risk for many physical and mental health disorders and increased overall mortality risk. In addition to social isolation, older adults are also at greater risk for osteoporosis and related fractures. While researchers have investigated the negative effects of other forms of psychosocial stress on bone, including depression and PTSD, the effects of social isolation on bone have not been thoroughly investigated. The aim of this study was to test the hypothesis that social isolation would lead to bone loss in male and female C57BL/6J mice. 16-week-old mice were randomized into social isolation (1 mouse/cage) or grouped housing (4 mice/cage) for four weeks (N=16/group). Social isolation significantly decreased trabecular (BV/TV, BMD, Tb. N., Tb. Th.) and cortical bone (Ct.Th., Ct.Ar., Ct.Ar./Tt.Ar., pMOI, Ct.Por.) parameters in male, but not female mice. Isolated male mice had signs of reduced bone remodeling represented by reduced osteoblast numbers, osteoblast-related gene expression and osteoclast-related gene expression. However, isolated females had increased bone resorption-related gene expression, without any change in bone mass. Overall, our data suggest that social isolation has negative effects on bone in males, but not females, although females showed suggestive effects on bone resorption. These results provide critical insight into the effects of isolation on bone and have key clinical implications as we grapple with the long-term health impacts of the rise in social isolation related to the COVID-19 pandemic.

Public mental health during and after the SARS-CoV-2 pandemic: Opportunities for intervention via emotional self-efficacy and resilience

Importance

During the pandemic, the number of United States adults reporting clinically significant symptoms of anxiety and depression sky-rocketed, up from 11% in 2020 to more than 40% in 2021. Our current mental healthcare system cannot adequately accommodate the current crisis; it is therefore important to identify opportunities for public mental health interventions.

Objective

Assess whether modifiable emotional factors may offer a point of intervention for the mental health crisis.

Design setting and participants

From January 13 to 15, 2022, adults living in the United States were recruited via Amazon Mechanical Turk to complete an anonymous survey.

Main outcomes and measures

Linear regressions tested whether the primary outcomes during the SARS-CoV-2 pandemic (depressive and anxiety symptoms, burnout) were associated with hypothesized modifiable risk factors (loneliness and need for closure) and hypothesized modifiable protective factors (the ability to perceive emotions and connect with others emotionally; emotion-regulation efficacy; and resilience, or the ability to "bounce back" after negative events).

Results

The sample included 1,323 adults (mean [SD] age 41.42 [12.52] years; 636 women [48%]), almost half of whom reported clinically significant depressive (29%) and/or anxiety (15%) symptoms. Approximately 90% of participants indicated feeling burned out at least once a year and nearly half of participants (45%) felt burned out once a week or more. In separate analyses, depressive symptoms (Model A), anxiety symptoms (Model B), and burnout (Model C) were statistically significantly associated with loneliness (βModel A, 0.38; 95% CI, 0.33-0.43; βModel B, 0.30; 95% CI, 0.26-0.36; βModel C, 0.34; 95% CI, 0.28-0.41), need for closure (βModel A, 0.09; 95% CI, 1.03-1.06; βModel B, 0.13; 95% CI, 0.97-0.17; βModel C, 0.11; 95% CI, 0.07-0.16), recent stressful life events (βModel A, 0.14; 95% CI, 0.10-0.17; βModel B, 0.14; 95% CI, 0.11-0.18; βModel C, 0.10; 95% CI, 0.06-0.15), and resilience (βModel A, -0.10; 95% CI, -0.15 to -0.05; βModel B, -0.18; 95% CI, -0.23 to -0.13; βModel C, -0.11; 95% CI, -0.17 to -0.05). In addition, depressive and anxiety symptoms were associated with emotional self-efficacy (βModel A, -0.17; 95% CI, -0.22 to -0.12; βModel B, -0.11; 95% CI, -0.17 to -0.06), and beliefs about the malleability of emotions (βModel A, -0.08; 95% CI, -0.12 to -0.03; βModel B, -0.09; 95% CI, -0.13 to -0.04). Associations between loneliness and symptoms were weaker among those with more emotional self-efficacy, more endorsement of emotion malleability beliefs, and greater resilience, in separate models. Analyses controlled for recent stressful life events, optimism, and social desirability.

Conclusion and relevance

Public mental health interventions that teach resilience in response to negative events, emotional self-efficacy, and emotion-regulation efficacy may protect against the development of depressive symptoms, anxiety, and burnout, particularly in the context of a collective trauma. Emotional self-efficacy and regulation efficacy may mitigate the association between loneliness and mental health, but loneliness prevention research is also needed to address the current mental health crisis.

Attending live sporting events predicts subjective wellbeing and reduces loneliness

Introduction

This study explored whether attending live sporting events (LSEs) improved subjective wellbeing and loneliness, above and beyond demographic predictors.

Methods

Secondary data from 7,249 adults from the Taking Part 2019-20 survey (UK household survey of participation in culture and sport) were analyzed. Multiple linear regressions captured the effect of attending LSEs (yes/no) on wellbeing variables (happiness, anxiety, a sense that life is worthwhile and life satisfaction) and loneliness, with gender, Index of Multiple Deprivation (IMD), age group, health and employment as covariates.

Results

For life satisfaction, a sense that life is worthwhile, and loneliness, inclusion of LSE attendance in the model improved model fit significantly, although ΔR² values were small (ΔR² = 0.001-0.003). For happiness and anxiety, the inclusion of LSE attendance did not alter model fit. LSE attendance was associated with increased life satisfaction (b = 0.171, p < 0.001), a greater sense of life being worthwhile (b = 0.230, p < 0.001), and reduced loneliness (b = -0.083, p < 0.01).

Conclusion

LSE attendance has positive associations with some aspects of subjective wellbeing (life satisfaction and a sense of life being worthwhile) and loneliness, above and beyond demographic predictors. Whilst the variance explained is small, it is comparable to demographic predictors (e.g., being in employment). As even small-sized differences in SWB can have meaningful outcomes (e.g., for mortality), we conclude that LSE attendance may still offer a scalable, accessible and effective means of improving the public's wellbeing and reducing loneliness.

The impact of loneliness on compliance with COVID-19 prevention guidelines

Many individuals have been reluctant to follow the COVID-19 prevention guidelines (e.g., wearing a mask, physical distancing, and vigilant handwashing) set forth by the U.S. Center for Disease Control to reduce the spread of COVID-19. In this research, we use reciprocal altruism theory to investigate the role of loneliness and its impact on compliance with these guidelines. Our findings indicate that lonely individuals are less willing to comply with COVID-19 prevention guidelines than non-lonely individuals. Process evidence suggests that this occurs as loneliness can inhibit an individual's sense of obligation to reciprocate to others. However, we demonstrate that framing information about COVID-19 through agentic (vs. communal) advertising messaging strategies can offset the negative impact of loneliness on compliance with COVID-19 prevention guidelines. Thus, marketers and policymakers may want to consider the important role of loneliness when tailoring messaging appeals that encourage compliance with COVID-19 prevention guidelines.

A Systematic Literature Review of Loneliness in Community Dwelling Older Adults

Research on loneliness is extensive. This paper presents a systematic review of intervention studies, outlining the antecedents to, and consequences of loneliness in community-dwelling older people. Using PRISMA methodology, a systematic literature review was conducted between January and August 2021 resulting in 49 useable articles. Papers were included if they: (a) investigated older people (+50); (b) were living in community dwellings; (c) had been published in English; (d) had titles or abstracts available and, (e) were published between 2016 and 2021. This study found the antecedents and consequences of social, emotional and existential loneliness differ, however, the vast majority of research has not examined the unique types of loneliness and instead kept loneliness as a generic term, despite the acceptance that various types of loneliness exist. In addition, the findings of intervention studies identified through this review have yielded mixed results. Those interventions focused on improving personal and psycho-social resources for older people fared better outcomes than those focused on technological and social connections alone. This paper reports important implications for the future of research conducted on loneliness and interventions accordingly.

The relationship between internet use preference and loneliness among college students during COVID-19: The chain mediating effect of online social support and self-esteem

The outbreak of COVID-19, especially the demands of social interaction and spatial distancing behavior, has led to a surge in Internet use, which has also led to an increase in loneliness. Therefore, we investigated the role of online social support and self-esteem in the relationship between Internet use preference and loneliness. In this study, 1053 college students were surveyed with a questionnaire based on the framework of Ecological System Theory, and a chain mediation model was established to clarify the mechanism between Internet use preference and loneliness. The results show that Internet use preference not only positively predicts loneliness, but also indirectly influences loneliness through the mediators of online social support and self-esteem, thereby impacting loneliness through the "online social support → self-esteem" chain. The results also indicate the need to pay attention to college students' mental health status during COVID-19. The advent of COVID-19 has impacted people's lifestyles and has changed the impact of the Internet on individual mental health. This study provides a new way to further understand college students' Internet use preferences, online social support, self-esteem, and loneliness status during COVID-19. It provides targeted interventions for college students' loneliness during COVID-19.

How Can Music Engagement Address Loneliness? A Qualitative Study and Thematic Framework in the Context of Australia's COVID-19 Pandemic Lockdowns

Social isolation and loneliness are serious public health concerns. Music engagement can strengthen social connections and reduce loneliness in some contexts, although how this occurs is not well understood; research suggests that music's capacity to manipulate perceptions of time and space is relevant. This study adopted a qualitative perspective to examine how music engagement shaped the experiences of residents of Victoria, Australia, during conditions of restricted social contact during the lockdowns of 2020. Semi-structured interviews explored participants' lived musical experiences while giving focus to perceptions of time and space (e.g., how music helped restructure home and workspaces in response to lockdown regulations, or punctuate time where older routines were no longer viable). Interpretative Phenomenological Analysis of the interview transcripts identified five themes representing the key findings: (1) a super-ordinate theme of perceived control, which comprises four themes: (2) dynamic connection; (3) identity; (4) mobility; (5) presence. Each theme describes one generalised aspect of the way music engagement shaped participants' perceptions of time and space during lockdown and supported their processes of adaptation to and coping with increased social isolation. The authors argue that these findings may inform the way music can be used to address loneliness in everyday life.

Association between household composition and severe COVID-19 outcomes in older people by ethnicity: an observational cohort study using the OpenSAFELY platform

BACKGROUND

Ethnic differences in the risk of severe COVID-19 may be linked to household composition. We quantified the association between household composition and risk of severe COVID-19 by ethnicity for older individuals.

METHODS

With the approval of NHS England, we analysed ethnic differences in the association between household composition and severe COVID-19 in people aged 67 or over in England. We defined households by number of age-based generations living together, and used multivariable Cox regression stratified by location and wave of the pandemic and accounted for age, sex, comorbidities, smoking, obesity, housing density and deprivation. We included 2 692 223 people over 67 years in Wave 1 (1 February 2020-31 August 2020) and 2 731 427 in Wave 2 (1 September 2020-31 January 2021).

RESULTS

Multigenerational living was associated with increased risk of severe COVID-19 for White and South Asian older people in both waves [e.g. Wave 2, 67+ living with three other generations vs 67+-year-olds only: White hazard ratio (HR) 1.61 95% CI 1.38-1.87, South Asian HR 1.76 95% CI 1.48-2.10], with a trend for increased risks of severe COVID-19 with increasing generations in Wave 2. There was also an increased risk of severe COVID-19 in Wave 1 associated with living alone for White (HR 1.35 95% CI 1.30-1.41), South Asian (HR 1.47 95% CI 1.18-1.84) and Other (HR 1.72 95% CI 0.99-2.97) ethnicities, an effect that persisted for White older people in Wave 2.

CONCLUSIONS

Both multigenerational living and living alone were associated with severe COVID-19 in older adults. Older South Asian people are over-represented within multigenerational households in England, especially in the most deprived settings, whereas a substantial proportion of White older people live alone. The number of generations in a household, number of occupants, ethnicity and deprivation status are important considerations in the continued roll-out of COVID-19 vaccination and targeting of interventions for future pandemics.

Loneliness in Kenyan adolescents: Socio-cultural factors and network association with depression and anxiety symptoms

Loneliness is associated with negative mental health outcomes and is particularly common among adolescents. Yet, little is known about the dynamics of adolescent loneliness in non-Western, low-income nations. Accordingly, we estimated the severity of loneliness in a sample of Kenyan adolescents and used mixed-effects regression modelling to determine the socio-cultural factors associated with loneliness. We also used network analysis to examine the associations between loneliness, depression, and anxiety at the symptom level. We analyzed data from a large sample (N = 2,192) of school-attending Kenyan adolescents aged 12-19 (58.3% female, 41.7% male). Standardized measures of loneliness (ULS-8), depression (PHQ-8), and anxiety (GAD-7) were used. Our mixed-effects model revealed that female and lower-income adolescents felt lonelier. The perception of feeling alone emerged as the aspect of loneliness most strongly linked to depression and anxiety symptoms. Our findings establish an estimate of loneliness levels in Kenyan adolescents, and identify possible socio-cultural factors associated with loneliness. We found that perceptions of isolation more strongly linked loneliness to psychopathology than did objective measures of isolation or preferences for social contact. Finally, we identify specific aspects of loneliness that could prove to be treatment targets for youth psychopathology; however, further research is needed. Limitations, future directions, and clinical implications are discussed.

Fear of contagion, emotional stress and coping strategies used by adults during the first wave of the COVID-19 pandemic in Nigeria

BACKGROUND

The COVID-19 pandemic has induced high levels of stress. The aim of the study was to assess the relationship between emotional stress (COVID-19 related fear, anger, frustration, and loneliness) and the use of coping strategies among adults in Nigeria during the COVID-19 pandemic.

METHODS

Data from adults aged 18 years and above were collected through an online survey from July to December 2020. The dependent variables were COVID-19 related fear (fear of infection and infecting others with COVID-19), anger, frustration, and loneliness. The independent variables were coping strategies (use of phones to communicate with family and others, video conferencing, indoor exercises, outdoor exercises, meditation/mindfulness practices, engaging in creative activities, learning a new skill, following media coverage related to COVID-19) and alcohol consumption. Five logistic regression models were developed to identify the factors associated with each dependent variables. All models were adjusted for sociodemographic variables (age, sex at birth, and the highest level of education).

RESULTS

Respondents who consumed alcohol, followed media coverage for COVID-19 related information, and who spoke with friends or family on the phone had higher odds of having fear of contracting COVID-19 or transmitting infection to others, and of feeling angry, frustrated, or lonely (p < 0.05). Respondents who exercised outdoors (AOR: 0.69) or learned a new skill (AOR: 0.79) had significantly lower odds of having fear of contracting COVID-19. Respondents who practiced meditation or mindfulness (AOR: 1.47) had significantly higher odds of feeling angry. Those who spoke with friends and family on the phone (AOR: 1.32) and exercised indoors (AOR: 1.23) had significantly higher odds of feeling frustrated. Those who did video conferencing (AOR: 1.41), exercised outdoors (AOR: 1.32) and engaged with creative activities (AOR: 1.25) had higher odds of feeling lonely.

CONCLUSION

Despite the significant association between emotional stress and use of coping strategies among adults in Nigeria during the COVID-19 pandemic, it appears that coping strategies were used to ameliorate rather than prevent emotional stress. Learning new skills and exercising outdoors were used to ameliorate the fear of contracting COVID-19 in older respondents.

Green space and loneliness: A systematic review with theoretical and methodological guidance for future research

Persistent loneliness troubles people across the life span, with prevalence as high as 61 % in some groups. Urban greening may help to reduce the population health impacts of loneliness and its concomitants, such as hopelessness and despair. However, the literature lacks both a critical appraisal of extant evidence and a conceptual model to explain how green space would work as a structural intervention. Both are needed to guide decision making and further research. We conducted a systematic review of quantitative studies testing associations between green space and loneliness, searching seven databases. Twenty two studies were identified by 25/01/2022. Most of the studies were conducted in high-income countries and fifteen (68 %) had cross-sectional designs. Green space was measured inconsistently using either objective or subjective indicators. Few studies examined specific green space types or qualities. The majority of studies measured general loneliness (e.g. using the UCLA loneliness scale). Different types of loneliness (social, emotional, existential) were not analysed. Of 132 associations, 88 (66.6 %) indicated potential protection from green space against loneliness, with 44 (33.3 %) reaching statistical significance (p < 0.05). We integrated these findings with evidence from qualitative studies to elaborate and extend the existing pathway domain model linking green space and health. These elaborations and extensions acknowledge the following: (a) different types of green space have implications for different types of loneliness; (b) multilevel circumstances influence the likelihood a person will benefit or suffer harm from green space; (c) personal, relational, and collective processes operate within different domains of pathways linking green space with loneliness and its concomitants; (d) loneliness and its concomitants are explicitly positioned as mediators within the broader causal system that links green space with health and wellbeing. This review and model provide guidance for decision making and further epidemiological research on green space and loneliness.

National Data on Age Gradients in Well-being Among US Adults

This survey study assesses well-being among US adults by age group.

Perceptions of social rigidity predict loneliness across the Japanese population

Loneliness is associated with mental and physical health problems and elevated suicide risk, and is increasingly widespread in modern societies. However, identifying the primary factors underlying loneliness remains a major public health challenge. Historically, loneliness was thought to result from a lack of high-quality social connections, but broader cultural factors (e.g. social norms) are increasingly recognized to also influence loneliness. Here, we used a large-scale survey (N = 4977) to assess to what degree the loneliness epidemic in Japan is associated with traditional measures of social isolation (number of close friends), cultural factors (perceptions of social rigidity, as measured by relational mobility), and socioeconomic factors (e.g. income). We confirmed that a lack of close friends is a dominant factor underlying loneliness in Japan. We also found that perceptions of the social rigidity in one's environment was a major correlate of loneliness. Subjects who perceived lower levels of rigidity in their social environments felt significantly less lonely than those who perceived higher levels of social rigidity, though the association was weak in low income males. Thus, Japanese society and other high social rigidity cultures may need to reflect on the possibility that inflexible traditional norms of socialization are exacerbating loneliness.

Psychosocial Determinants of Loneliness in the Era of the COVID-19 Pandemic-Cross-Sectional Study

BACKGROUND

The COVID-19 pandemic affected the mental health and social behavior of people around the world. Due to epidemiological restrictions, the period of forced isolation contributed to the feeling of loneliness. The aim of the research is to identify factors and conditions associated to the feeling of loneliness in the era of the COVID-19 pandemic.

METHODS

The survey was conducted among 262 people from the north-eastern Polish area, using an online survey. The diagnostic survey method was used, using the De Jong Gierveld Loneliness Measurement Scale, the Generalized Self-Efficacy Scale (GSES), the WHOQoL-Bref questionnaire.

RESULTS

A statistically significant relationship was observed between the feeling of loneliness and areas of quality of life, especially psychological and social, generalized self-efficacy and marital status and way of living (p < 0.05). Higher levels of stress, social distancing, restrictions at work, health status were significantly correlated with an increase in loneliness. Remote work was associated with a lower assessment of the quality of life in the psychological field (p < 0.05).

CONCLUSIONS

Higher levels of loneliness were significantly more likely to affect people living alone and not in a relationship. Higher levels of loneliness were significantly associated with lower quality of life in the social and psychological domains, lower levels of self-efficacy, and remote work.

Early life adverse experiences and loneliness among young adults: The mediating role of social processes

Loneliness has been described as endemic among young people. Such feelings of social isolation 'even in a crowd' are likely linked to adverse early life experiences that serve to diminish perceptions of social support and intensify negative social interactions. It was suggested in the present series of survey studies that childhood abuse, which compromises a child's sense of safety in relationships, may affect social processes that contribute to loneliness in young adulthood. Study 1 assessed different adverse childhood and adult experiences in relation to loneliness among young adults (N = 171). Linear regression analyses indicated that childhood abuse was uniquely associated with greater loneliness, and this relationship was partially mediated by the perceived availability of social support. Study 2 (N = 289) assessed different forms of childhood abuse and demonstrated that early life emotional abuse was a unique predictor of loneliness, and this relationship was fully mediated by lower perceived support or value in social connections (social connectedness) and more frequent unsupportive interactions with friends. Study 3 evaluated the implications of the age of occurrence of abuse (N = 566). Both emotional and sexual abuse predicted young adult loneliness regardless of age; abuse that was recalled to have occurred at very early ages (0-5 years) was not predictive of loneliness over and above consideration of events that happened in older childhood. These relationships were at least partially mediated by perceived social support, social connectedness, and in the case of emotional abuse, unsupportive interactions with friends. Our results add to mounting evidence pointing to the prevalence of loneliness among young adults and the links to adverse early life experiences that may serve to shape appraisals of safety, value, and personal worth in social relationships.

General psychiatric symptoms among Bangladeshi people approximately one year after the onset of the COVID-19 pandemic

BACKGROUND

Coronavirus disease-2019 (COVID-19) has had negative physical and mental impacts on people globally. The current study examined general psychiatric symptoms (fear, anxiety, depression, and insomnia) and loneliness, and their interrelationships and correlates among Bangladeshi individuals approximately 1 year after the onset of the COVID-19 outbreak.

METHODS

An internet-based cross-sectional survey was conducted among 1004 Bangladeshi people (51.8% male; mean age: 25.41 ± 7.80; age range: 18-60 years). Data were collected using a semi-structured e-questionnaire including informed consent, socio-demographics, lifestyle measures, and psychometric tools assessing loneliness, anxiety, depression, insomnia, and fear of COVID-19.

RESULTS

Sizeable participants screened positive for loneliness (63.5%), anxiety (26.3%), depression (46.4%), and insomnia (50.7%). Considerable numbers of respondents also reported fear of COVID-19. In hierarchical regression analyses, loneliness, anxiety, depression, insomnia, and fear of COVID-19 were associated with socio-demographic and lifestyle factors. Loneliness, anxiety, depression, insomnia, and fear of COVID-19 were positively correlated with each other (p < 0.001). In exploratory path analyses, anxiety, depression, and insomnia mediated the relationship between loneliness and fear of COVID-19.

CONCLUSIONS

The findings indicate that many people in Bangladesh have experienced psychiatric concerns approximately 1 year after the onset of the COVID-19 outbreak. Investigation into empirically supported interventions and their implementation is needed.

A Longitudinal Study on Loneliness during the COVID-19 Pandemic in Japan

The prolonged COVID-19 pandemic has exacerbated existing socioeconomic and health risk factors and added additional dimensions to the loneliness problem. Considering the temporal extension of COVID-19, which exposes people to various loneliness conditions, we examined the development of loneliness and changing risk factors based on age and gender. We used longitudinal data from Hiroshima University's nationwide survey in Japan, conducted before and during the pandemic, to categorize loneliness into three types: long-term (feeling of loneliness experienced both before and during the pandemic), post-pandemic (feeling of loneliness experienced throughout the whole pandemic period), and fresh (feeling of loneliness experienced only in the last year of the pandemic). Loneliness categorization is important because the prolonged existence of the COVID-19 pandemic has added additional dimensions to the loneliness problem, which existing studies rarely identify. As a result, the distinction between long-term and fresh loneliness remains unexplained. The weighted logit regression results revealed that many Japanese people have remained or became lonely during the pandemic and identified variations based on gender, age, and changes in socioeconomic and health characteristics. More precisely, almost 52% of the participants experienced long-term loneliness, while 8% of the participants experienced post-pandemic loneliness, and nearly 5% experienced fresh loneliness. Age and having children were associated with long-term loneliness; gender, age, leaving full-time employment, financial literacy, change in health status, and change in depression were associated with post-pandemic loneliness; and gender, having children, living in rural areas, change in household assets, financial literacy, changes in health status, and changes in depression were associated with fresh loneliness. These results indicated that long-term, post-pandemic, and fresh loneliness have distinct characteristics. The Japanese government should devise distinctive solutions for people suffering from varying loneliness before and during the pandemic rather than adopting a generalized approach.

An eight country cross-sectional study of the psychosocial effects of COVID-19 induced quarantine and/or isolation during the pandemic

Forced quarantine and nationwide lockdowns have been a primary response by many jurisdictions in their attempt at COVID-19 elimination or containment, yet the associated mental health burden is not fully understood. Using an eight country cross-sectional design, this study investigates the association between COVID-19 induced quarantine and/or isolation on probable generalized anxiety disorder (GAD) and major depressive episode (MDE) psychological outcomes approximately eight months after the pandemic was declared. Overall, 9027 adults participated, and 2937 (32.5%) were indicated with GAD and/or MDE. Reported quarantine and/or isolation was common, with 1199 (13.8%) confined for travel or health requirements, 566 (6.5%) for being close contact, 720 (8.3%) for having COVID-19 symptoms, and 457 (5.3%) for being COVID-19 positive. Compared to those not quarantining or isolating, the adjusted estimated relative risks of GAD and/or MDE associated with quarantine and/or isolation was significant (p < 0.001), ranging from 1.24 (95% confidence interval [CI]: 1.07, 1.43) for travel/health to 1.37 (95% CI 1.19, 1.59) for COVID-19 symptom isolation reasons. While almost universally employed, quarantine and/or isolation is associated with a heavy mental health toll. Preventive strategies are needed, such as minimizing time-limits imposed and providing clear rationale and information, together with additional treatment and rehabilitation resources.

Healing in Health Care: Mental Health Promotion, Advocacy, and Voluntarism in Response to COVID-19

The COVID-19 pandemic increased many known risk factors for mental health problems. In the context of overwhelmed health systems and resource and staffing shortages, the mental health needs of frontline health care workers (HCWs) gained attention as a major public health concern and a threat to high-quality care delivery. In response, mental health promotion initiatives were quickly developed to meet the demands of the public health crisis. Two years later, the context for psychotherapy has changed, especially as it pertains to the health care workforce. Particularly salient experiences-grief, burnout, moral injury, compassion fatigue, and racial trauma-have become routinely discussed as part of everyday clinical practice. Service programs have become more responsive to the needs, schedules, and identities of HCWs. In addition, mental health and other HCWs have contributed to advocacy and volunteer initiatives promoting health equity, culturally responsive care, and access to care across a range of settings. In this article, the authors review the benefits of these activities to individuals, organizations, and communities and summarize example programs. Many of these initiatives began in response to the acute public health crisis; however, engaging in these ways and spaces holds promise for increasing connection and prioritizing equity and structural change over the long term.

A systematic review of loneliness and social isolation among Hispanic/Latinx older adults in the United States

Loneliness and social isolation are growing public health problems in older adults, associated with physical and mental comorbidity and increased mortality. In the United States, Hispanic/Latinx individuals constitute the largest racial/ethnic minority. Studies retrieved from PsycInfo, Embase, and PubMed were examined. The initial search yielded 1476 publications. Using the updated PRISMA Flow guidelines, a total of 17 studies met our review criteria. Eight studies assessed loneliness, six evaluated social isolation, and three investigated both. The reports varied in the details of methodology, preventing meta-analyses. Differences in the experience of loneliness and social isolation between Hispanic/Latinx and White adults are not consistent. Of the three studies of loneliness or social isolation among Hispanic/Latinx groups of different national origins, two reported significant differences. Loneliness was associated with greater overall comorbidity, but two studies found higher risk of metabolic and cardiovascular disorders in Hispanic/Latinx with loneliness. Social isolation was generally associated with worse physical health, being older, male, and unmarried, and having lower education and income, and more smoking, along with frailty and cognitive impairment. We make specific suggestions for future research on loneliness and social isolation in Hispanic/Latinx adults and offer guidelines for clinical management.

Meta-analytic evidence for the cognitive control model of loneliness in emotion processing

Loneliness is strongly related to affective dysregulation. However, the neuropsychological mechanisms underpinning the loneliness-affective processing relationships remain unclear. Here, we first utilised the coordinate-based activation likelihood estimation method to confirm functional clusters related to loneliness, including the striatum, superior and medial frontal gyrus, insula, and cuneus. Meta-analytic connectivity modelling was then performed to characterise the functional connectivity of these clusters across studies using emotion tasks. Our results revealed that these clusters co-activated with the cognitive control networks. From the literature, we understand that loneliness and its neural correlates are highly related to regulating the attention biases to social rewards and social cues. Therefore, our findings provide a proof-of-concept that loneliness up-regulates the cognitive control networks to process socio-affective information. Prolonged up-regulation thus exhausts cognitive resources and hence, affective dysregulation. This study offers insight into the intricate role of cognitive and affective regulation in loneliness and social perception and provides meta-analytic evidence of the cognitive control model of loneliness and loneliness-related affective dysregulation, bringing significant clinical implications.

Exploring the demographic and situational characteristics of older British people experiencing loneliness as positive within the BBC loneliness experiment

OBJECTIVES

The aim of this study is to increase the understanding of loneliness experienced as positive, by exploring the demographic and situational characteristics of older people who experience loneliness as positive.

METHOD

Two binary logistic regressions were conducted using data from those aged 60+ from the BBC Loneliness Experiment (N = 5250).

RESULTS

The first binary logistic regression compared participants who experience loneliness always as positive (N = 219) to those participants who never experience loneliness as positive (N = 3004). Spending time alone did not emerge as relevant to experiencing loneliness as positive, but enjoying time alone was important (OR = 1.561 (95% CI = 1.313 - 1.856)). The lonelier older people were, the less likely they experienced loneliness as positive (OR = 0.708 (95% CI =0.644 - 0.779)). Men were more likely to experience loneliness as positive compared to women (OR = 1.734 (95% CI = 1.269 - 2.370)). Lastly, the experience of loneliness as positive was likely to decrease when older people had more years of education (OR = 0.887 (95% CI = 0.853 - 0.921)) but increased with age (OR = 1.067 (95% CI = 1.037 - 1.098)). The results of the second binary logistic regression comparing participants who indicated loneliness purely as positive with those participants indicate to experience loneliness sometimes as positive (N = 2027), are in line with the first regression analyses.

CONCLUSION

The results are critically discussed by emphasizing the role of norms and cultures, gerotranscendence, and severity of loneliness, which might influence the experiences of loneliness. Further qualitative research is needed to elucidate the meanings of these positive experiences of loneliness.

Social isolation and oxytocin antagonism increase emotion-related behaviors and heart rate in female prairie voles

Social isolation influences depression- and anxiety-related disorders and cardiac function. Oxytocin may mediate these conditions through interactions with social behavior, emotion, and cardiovascular function, via central and/or peripheral mechanisms. The present study investigated the influence of oxytocin antagonism using L-368,899, a selective oxytocin receptor antagonist that crosses the blood-brain barrier, on depression- and anxiety-related behaviors and heart rate in prairie voles. This rodent species has translational value for investigating interactions of social stress, behavior, cardiac responses, and oxytocin function. Adult female prairie voles were socially isolated or co-housed with a sibling for 4 weeks. A subset of animals in each housing condition was subjected to 4 sessions of acute L-368,899 (20 mg/kg, ip) or saline administration followed by a depression- or anxiety-related behavioral assessment. A subset of co-housed animals was evaluated for cardiac function following acute administration of L-368,899 (20 mg/kg, ip) and during behavioral assessments. Social isolation (vs. co-housing) increased depression- and anxiety-related behaviors. In isolated animals, L-368,899 (vs. vehicle) did not influence anxiety-related behaviors but exacerbated depression-related behaviors. In co-housed animals, L-368,899 exacerbated depression-related behaviors and increased heart rate at baseline and during behavioral tests. Social isolation produces emotion-related behaviors in prairie voles; central and/or peripheral oxytocin antagonism exacerbates these behavioral signs. Oxytocin antagonism induces depression-relevant behaviors and increases basal and stressor-reactive heart rate in co-housed prairie voles, similar to the consequences of social isolation demonstrated in this model. These results provide translational value for humans who experience behavioral and cardiac consequences of loneliness or social stress.

Emotional and Mental Wellbeing Following COVID-19 Public Health Measures on People Living With Dementia and Carers

BACKGROUND

To date, there appears to be no evidence on the longer-term impacts caused by COVID-19 and its related public health restrictions on some of the most vulnerable in our societies. The aim of this research was to explore the change in impact of COVID-19 public health measures on the mental wellbeing of people living with dementia (PLWD) and unpaid carers.

METHOD

Semi-structured, follow-up telephone interviews were conducted with PLWD and unpaid carers between June and July 2020. Participants were asked about their experiences of accessing social support services during the pandemic, and the impact of restrictions on their daily lives.

RESULTS

20 interviews were conducted and thematically analyzed, which produced 3 primary themes concerning emotional responses and impact to mental health and wellbeing during the course of the pandemic: 1) Impact on mental health during lockdown, 2) Changes to mental health following easing of public health, and 3) The long-term effect of public health measures.

CONCLUSIONS

The findings from this research shed light on the longer-term psychological impacts of the UK Government's public health measures on PLWD and their carers. The loss of social support services was key in impacting this cohort mentally and emotionally, displaying a need for better psychological support, for both carers and PLWD.

Interventions to reduce loneliness in caregivers: An integrative review of the literature

Older adults are at an increased risk of loneliness. Many also serve as informal caregivers for persons with dementia and other disabling conditions, further predisposing them to loneliness. The primary objective was to assess current loneliness interventions for caregivers to inform development of effective therapies to improve their quality of life. An integrative review of the literature was conducted using five electronic databases and 12 studies were included for further analysis. Data were extracted regarding the type of intervention implemented, caregiver characteristics, and intervention effects. Five main intervention types emerged: mindful meditation, computer applications, music therapy, peer support, and community programs. Most care recipients had dementia, and most caregivers were spouses. Peer support was the most frequently utilized intervention, and common intervention strategies included providing emotional support, expanding one's social network, and supplying psychoeducational materials. Most interventions had methodological limitations and demonstrated small effect sizes. Hence, there remains a continued need for well-designed interventions that target loneliness in informal caregiver. Caregivers may benefit from interventions that expand their social network to improve their emotional regulation and understanding of their role. Further research on the role of group versus individual therapy is necessary to strengthen interventions and broaden their application.

Association Between Loneliness and Sleep-Related Problems Among Japanese Workers During the COVID-19 Pandemic

Background

The coronavirus disease 2019 (COVID-19) pandemic has been linked to a rise in loneliness. Loneliness is associated with sleep-related problems, which in turn can be a risk factor for various psychiatric disorders. However, it is unclear whether loneliness is linked to sleep-related problems during the pandemic. Here, we studied the association between loneliness and sleep-related problems during the COVID-19 pandemic in Japan.

Methods

A total of 33,302 individuals who indicated they were employed were surveyed online. The survey responses of 27,036 participants were analyzed. Odds ratios (ORs) were estimated using univariate and multiple logistic regression analyses.

Results

Of those analyzed, 2,750 (10.2%) experienced feelings of loneliness. Further, sleep-related problems were significantly more common among those who felt lonely both in the short term (more than 3 days) and the long term (more than 3 months). The ORs were much weaker after adjusting for factors related to interpersonal connections, such as family and friendships, than after adjusting for factors related to socioeconomic status.

Conclusion

Loneliness may be a risk factor for sleep-related problems in the COVID-19 pandemic. Having connections with family and friends may have a moderating effect on the occurrence of sleep-related problems.

Social isolation, loneliness and mental health sequelae of the Covid-19 pandemic in Parkinson's disease

People living with Parkinson Disease (PwP) have been at risk for the negative effects of loneliness even before the Coronavirus Disease 2019 (Covid-19) pandemic. Despite some similarities with previous outbreaks, the Covid-19 pandemic is significantly more wide-spread, long-lasting, and deadly, which likely means demonstrably more negative mental health issues. Although PwP are not any more likely to contract Covid-19 than those without, the indirect negative sequelae of isolation, loneliness, mental health issues, and worsening motor and non-motor features remains to be fully realized. Loneliness is not an isolated problem; the preliminary evidence indicates that loneliness associated with the Covid-19 restrictions has dramatically increased in nearly all countries around the world.

Mother's Loneliness: Involuntary Separation of Pregnant Women in Maternity Care Settings and Its Effects on the Experience of Mothers during the COVID-19 Pandemic

The aim of the study was to investigate the challenges of involuntary separation experienced by women during pregnancy and childbirth in the time of the COVID-19 pandemic. The study was conducted by the means of a self-administered questionnaire. One thousand and eleven women (1011) from Poland took part in the study, with an average age of approximately 30 years. The study was approved by the Research Ethics Committee of Warmia and Mazury University in Olsztyn, Poland. The results show that the majority of the surveyed women experienced involuntary separation from their partners during pregnancy and childbirth: 66.27% had no choice but to give birth alone and 84.37% had not been able to attend medical appointments with their partners. Solitary encounters with healthcare were associated with the feeling of fear (36.4%), anger (41%), a sense of injustice (52.2%), acute sadness (36.6%) and a sense of loss (42.6%), with all the reported levels higher in younger women. Over 74% of respondents were afraid of childbirth without a partner present. Almost 70% felt depressed because of a lonely delivery experience. Nearly a quarter of the mothers surveyed declared that if they could go back in time, they would not have made the decision to become pregnant during the pandemic. Based on our study, we found that adjustments to prenatal and neonatal care arrangements under COVID-19-related regimens are needed. Our proposal is to implement at least three fundamental actions: (1) risk calculations for pandemic-related cautionary measures should take into account the benefits of the accompanied medical appointments and births, which should be restored and maintained if plausible; (2) medical personnel should be pre-trained to recognise and respond to the needs of patients as a part of crisis preparedness. If the situation does not allow the patient to stay with her family during important moments of maternity care, other forms of contact, including new technologies, should be used; (3) psychological consultation should be available to all patients and their partners. These solutions should be included in the care plan for pregnant women, taking into account a risk-benefit assessment.

A Solution for Loneliness in Rural Populations: The Effects of Osekkai Conferences during the COVID-19 Pandemic

Social prescribing is an essential solution to the lack of social connection and interaction and provides a key approach to problems faced by communities during the COVID-19 pandemic. One social prescription used in Japan is the Osekkai conference, which has the potential to increase social participation in rural communities. The revitalization of Osekkai can improve social interactions among people involved in the conference, thereby reducing loneliness. This interventional study was conducted with people who participated in the Osekkai conference. The primary outcomes of the degree of loneliness were compared between 2021 and 2022 using the Japanese version of the three-item UCLA Loneliness Scale. The demographic data and process outcomes of participants were measured using a questionnaire. The participants’ roles in the Osekkai conference increased between the two periods. Loneliness scores tended to decrease during the study period (4.25 to 4.05, p = 0.099). In the questionnaire on loneliness, the scores for item 2 decreased significantly during the study period (1.36 to 1.25, p = 0.038). In conclusion, this study shows that the continual provision of Osekkai conferences as a social prescription may reduce the degree of loneliness among participants with improved social participation in rural communities. Future studies should investigate comparative interventions to show the effectiveness of social prescription on loneliness in communities.

A link between social isolation during the coronavirus outbreak and social alignment in balcony parties

With the ongoing COVID-19 pandemic, there is a growing need for assessing the psychological costs of social isolation (SI). We examine whether the balcony party during the first outbreak of the pandemic is associated with how individuals cope with SI as well as its causes and consequences during the COVID-19 outbreak. A total of 303 quarantined persons responded to a Web-based survey. We found that the effect of balcony parties on the psychological costs of SI is dependent on the self-reported levels of SI. Those who experienced high levels of causes of SI perceived the balcony parties as more beneficial in inducing positive affect and reducing negative affect in comparison to those who experienced low levels of causes of SI. The opposite pattern was observed when individuals were asked about their participation in these parties: individuals with high levels of consequences of SI experienced balcony parties as less beneficial than similar pre-outbreak gathering events, while individuals with low levels of consequences of SI showed an opposite pattern. Finally, for those with high levels of causes of SI and consequences of SI, balcony parties did not meet the expectation of creating feelings of communal solidarity. However, a discrepancy between high SI expectations and experience was not found for those with low SI. Our findings demonstrate that the balcony parties are beneficial in reducing the emotional cost of social isolation–but only for those who feel low levels of SI. The fact that individuals with high levels of SI expected more out of these parties suggests the need to develop interventions aimed at optimizing their expectations. As society enters a new period in which the costs of social distancing may be higher, our findings are valuable for understanding the psychological battle that individuals face while in social isolation.

Age differences in the association between loneliness and anxiety symptoms during the COVID-19 pandemic

Loneliness and associated mental health problems are of particular concern during the COVID-19 pandemic due to physical distancing and lockdown restrictions. Loneliness is most common among young adults and women during the pandemic, but it is unclear if the association between loneliness and mental health problems, notably anxiety, is strongest in these groups. The objective of this study was to examine whether the association between loneliness and anxiety differed by age and/or gender during the pandemic. We analyzed data from a multi-wave national online survey of Canadians aged 18+ years from May 2020 to March 2021 (n = 7,021). Multivariable modified least-squares regression was used to examine whether the association between loneliness and moderate to severe anxiety symptoms (GAD-7 10+) differed by age and/or gender on the additive scale, controlling for socio-demographic factors, depression, hopefulness, and survey wave. Age significantly moderated the association between loneliness and anxiety symptoms while gender did not. Loneliness was associated with anxiety symptoms for all age groups, but the association was not as strong among those aged 70+ years compared to other age groups. Evidence-based loneliness interventions that target younger adults are needed to mitigate the mental health effects of infectious disease events such as COVID-19.

Behavioral and Neural Dissociation of Social Anxiety and Loneliness

Loneliness is a public health concern with detrimental effects on physical and mental well-being. Given phenotypical overlaps between loneliness and social anxiety (SA), cognitive-behavioral interventions targeting SA might be adopted to reduce loneliness. However, whether SA and loneliness share the same underlying neurocognitive mechanisms is still an elusive question. The current study aimed at investigating to what extent known behavioral and neural correlates of social avoidance in SA are evident in loneliness. We used a prestratified approach involving 42 (21 females) participants with high loneliness (HL) and 40 (20 females) participants with low loneliness (LL) scores. During fMRI, participants completed a social gambling task to measure the subjective value of engaging in social situations and responses to social feedback. Univariate and multivariate analyses of behavioral and neural data replicated known task effects. However, although HL participants showed increased SA, loneliness was associated with a response pattern clearly distinct from SA. Specifically, contrary to expectations based on SA differences, Bayesian analyses revealed moderate evidence for equal subjective values of engaging in social situations and comparable amygdala responses to social decision-making and striatal responses to positive social feedback in both groups. Moreover, while explorative analyses revealed reduced pleasantness ratings, increased striatal activity, and decreased striatal-hippocampal connectivity in response to negative computer feedback in HL participants, these effects were diminished for negative social feedback. Our findings suggest that, unlike SA, loneliness is not associated with withdrawal from social interactions. Thus, established interventions for SA should be adjusted when targeting loneliness.SIGNIFICANCE STATEMENT Loneliness can cause serious health problems. Adapting well-established cognitive-behavioral therapies targeting social anxiety might be promising to reduce chronic loneliness given a close link between both constructs. However, a better understanding of behavioral and neurobiological factors associated with loneliness is needed to identify which specific mechanisms of social anxiety are shared by lonely individuals. We found that lonely individuals show a consistently distinct pattern of behavioral and neural responsiveness to social decision-making and social feedback compared with previous findings for social anxiety. Our results indicate that loneliness is associated with a biased emotional reactivity to negative events rather than social avoidance. Our findings thus emphasize the distinctiveness of loneliness from social anxiety and the need for adjusted psychotherapeutic protocols.

The Impact of COVID-19 Lockdown on Daily Activities, Cognitions, and Stress in a Lonely and Distressed Population: Temporal Dynamic Network Analysis

Background

The COVID-19 pandemic and its associated lockdown measures impacted mental health worldwide. However, the temporal dynamics of causal factors that modulate mental health during lockdown are not well understood.

Objective

We aimed to understand how a COVID-19 lockdown changes the temporal dynamics of loneliness and other factors affecting mental health. This is the first study that compares network characteristics between lockdown stages to prioritize mental health intervention targets.

Methods

We combined ecological momentary assessments with wrist-worn motion tracking to investigate the mechanism and changes in network centrality of symptoms and behaviors before and during lockdown. A total of 258 participants who reported at least mild loneliness and distress were assessed 8 times a day for 7 consecutive days over a 213-day period from August 8, 2020, through March 9, 2021, in Germany, covering a “no-lockdown” and a “lockdown” stage. COVID-19–related worry, information-seeking, perceived restriction, and loneliness were assessed by digital visual analog scales ranging from 0 to 100. Social activity was assessed on a 7-point Likert scale, while physical activity was recorded from wrist-worn actigraphy devices.

Results

We built a multilevel vector autoregressive model to estimate dynamic networks. To compare network characteristics between a no-lockdown stage and a lockdown stage, we performed permutation tests. During lockdown, loneliness had the highest impact within the network, as indicated by its centrality index (ie, an index to identify variables that have a strong influence on the other variables). Moreover, during lockdown, the centrality of loneliness significantly increased. Physical activity contributed to a decrease in loneliness amid the lockdown stage.

Conclusions

The COVID-19 lockdown increased the central role of loneliness in triggering stress-related behaviors and cognition. Our study indicates that loneliness should be prioritized in mental health interventions during lockdown. Moreover, physical activity can serve as a buffer for loneliness amid social restrictions.

Motivation to Participate in Intergenerational Programs: A Comparison across Different Program Types and Generations

Much research has attested to the benefits of intergenerational programs (IGPs) for older and younger participants, but there is a lack of understanding about what motivates them to participate and to persevere. We conducted structured interviews with 83 older (mean age = 77) and 96 younger (mean age = 23) participants who participated in 13 IGPs in Israel, some involving specific topics, and some providing assistance to older adults. Using a mixed-methods approach, we analyzed differences in motivation across generations and program types and compared initial and ongoing motivation to participate. We found differences regarding motivation by age group and program type: Among older participants, interest in the specific subject was a more prevalent motivation in topic-focused groups, while receiving support was more common in assistance groups. Among young persons, motivations relating to obligation, such as receipt of a financial scholarship, and the wish to help others were the most prevalent motivators. Ongoing motivation was often explained by positive intergenerational relationships and enjoyment. For older adults, offering more diverse topic-focused activities may motivate greater participation. For young adults, integrating IGPs within more and different settings, and promoting IGPs as opportunities to help others are potential motivators.

Evaluation of the Efficacy of Two Internet-based Self-help Interventions for Chronic Loneliness: Study Protocol for a Three-arm Randomized Controlled Trial (Preprint)

Background

Loneliness, or perceived social isolation, is prevalent in both the general population and clinical practice. Although loneliness has repeatedly been associated with mental and physical health, research on interventions that reduce loneliness effectively is still rather scarce.

Objective

This study aims to evaluate the efficacy of a guided and an unguided version of the same internet-based cognitive behavioral self-help program for loneliness (SOLUS-D) for adults.

Methods

A total of 250 participants will be randomly assigned to 1 of 2 intervention groups (SOLUS-D with guidance or SOLUS-D without guidance) or a wait-list control group (2:2:1 allocation ratio). Adult participants experiencing high levels of loneliness will be recruited from the general population. Individuals currently experiencing at least moderately severe depressive symptoms, an ongoing severe substance use disorder, previous or current bipolar or psychotic disorder, or acute suicidality will be excluded from the trial. Assessments will take place at baseline, 5 weeks (midassessment), and 10 weeks (postassessment). The primary outcome is loneliness assessed using the 9-item University of California, Los Angeles Loneliness Scale at the posttreatment time point. Secondary outcomes include depressive symptoms, symptoms of social anxiety, satisfaction with life, social network size, and variables assessing cognitive bias and social behavior. The maintenance of potentially achieved gains will be assessed and compared at 6 and 12 months after randomization in the 2 active conditions. Potential moderators and mediators will be tested exploratorily. Data will be analyzed on an intention-to-treat basis.

Results

Recruitment and data collection started in May 2021 and are expected to be completed by 2022, with the 12-month follow-up to be completed by 2023. As of the time of submission of the manuscript, 134 participants were randomized.

Conclusions

This 3-arm randomized controlled trial will add to the existing research on the efficacy of loneliness interventions. Furthermore, it will shed light on the role of human guidance in internet-based treatments for individuals with increased levels of loneliness and the possible mechanisms of change. If SOLUS-D proves effective, it could provide a low-threshold, cost-efficient method of helping and supporting individuals with increased levels of loneliness.

From society to cells and back again: new opportunities for discovery at the biosocial interface

A new generation of community- and population-based research is combining measures of social context, experience, and behavior with direct measures of physiology, gene sequence and function, and health. Studies drawing on models and methods from the social and biological sciences have the potential to illuminate the multilevel mechanisms through which experience becomes biology, and to move past decontextualized and reductionistic approaches to human development, behavior, and health. In this perspective we highlight challenges and opportunities at the biosocial interface, and briefly discuss COVID-19 as a case study demonstrating the importance of linking across levels of analysis.

Loneliness, Social Isolation, and All-Cause Mortality in a Large Sample of Older Adults

Objectives

Using data from a large random sample of U.S. older adults (N = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects.

Methods

The UCLA-3 Loneliness Scale and the Social Network Index (SNI) were used to define loneliness and social isolation. Cox proportional hazards regression models were performed.

Results

Among study participants, there were 548 deaths. In separate, adjusted models, loneliness (severe and moderate) and social isolation (limited and moderate social network) were both associated with all-cause mortality. When modeled together, social isolation (limited and moderate social network) along with severe loneliness remained significantly associated with mortality.

Discussion

Results demonstrate that both loneliness and social isolation contribute to greater risk of mortality within our population of older adults. As the COVID-19 pandemic continues, loneliness and social isolation should be targeted safely in efforts to reduce mortality risk among older adults.

Behavioral Epidemic of Loneliness in Older U.S. Military Veterans: Results From the 2019-2020 National Health and Resilience in Veterans Study

OBJECTIVE

This study aimed to characterize the current prevalence of loneliness, and the relation between loneliness severity and mental and physical health conditions, suicidality, and functional measures in a predominantly older sample of U.S. military veterans.

METHODS

This cross-sectional study used data from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. veterans (N = 4,069; mean age = 62) from November 2019 through March 2020. Veterans were classified into one of 3 groups based on their current level of loneliness (hardly ever, sometimes, often) on an adapted version of the Revised UCLA Loneliness Scale. A comprehensive range of mental and physical health, and functioning variables were assessed using valid and reliable self-report assessments.

RESULTS

A total of 56.9% of veterans endorsed feeling lonely sometimes (37.2%) or often (19.7%). Loneliness severity was independently associated with a range of mental health (odds ratios [ORs] = 1.21-33.30), physical health (ORs = 1.21-6.80), and functional difficulties (d's = 0.09-0.59). Relative to hardly ever feeling lonely, feeling lonely often or sometimes was associated with a more than 12- and three-fold greater likelihood of current suicidal ideation (29.0% versus 7.3% versus 1.5%), even after adjustment for sociodemographic, military, and psychiatric risk factors.

CONCLUSIONS

Loneliness is highly prevalent in U.S. military veterans, with more than half endorsing feeling lonely sometimes or often, and 1-of-5 reporting feeling lonely often. Loneliness severity was independently associated with a broad range of mental and physical health and functional measures, ias well as suicidal ideation. Results underscore the importance of loneliness as a transdiagnostic prevention and intervention target in the U.S. veteran population.

Adverse Effects from the Imposition of Social Restrictions in Greece: the Indirect Effect of COVID-19-Related Fear on Alcohol Consumption Through Loneliness

Quarantine and social distancing are crucial factors in blocking the consequences of COVID-19 but also can lead to higher levels of loneliness and social isolation. Therefore, any advantages of mandatory quarantine have to be weighed against any negative impact on physical and mental well-being. This study aimed to examine the relationship between COVID-19-related fear and alcohol use during the lockdown period and loneliness as a mediating factor increasing the impact of COVID-19-related fear on alcohol use. A sample of 279 young adults completed self-reported questionnaires on COVID-19-related fear, loneliness, and substance use. This exploratory cross-sectional research was administered from 11 until December 18, 2020. The results showed that loneliness during lockdown mode may exacerbate the emotional burden caused by COVID-19-related fear leading to increased alcohol consumption as a coping mechanism against unsatisfactory living conditions. This study’s results reflect the need for societal groups, as well as health care services to remain specifically considerate to the needs of individuals who report high levels of COVID-19-related fear and loneliness.

Feminist Loneliness Studies: an introduction

Writing about loneliness has been a struggle in the midst of the pandemic. Characterized by loneliness, isolation, anxiety, and fear, the COVID-19 pandemic is an exceptionally challenging time. At various points while navigating this loneliness project amid a particularly lonely time, we lamented the seeming futility of it all. A main goal of developing a Feminist Loneliness Studies in this introduction is to understand the ways that systems of oppression – white supremacy, settler colonialism, anti-queer bias, misogyny, neoliberal capitalism, and so on – create our lonely world. To date, there remains no comprehensive feminist analysis of the structural conditions that both produce and intensify experiences of loneliness. We aim to remedy this gap. That is, we seek to address what a Feminist Loneliness Studies can contribute to understanding the complexities of this complicated emotion. For example, what is the unique loneliness of the feminist killjoy who calls out, or calls in, existing forms of queerphobia, racism, and sexism? What does it mean to be a politicized person and how does that result in both alienation and isolation? What might the relationship be between white supremacy and loneliness? How is loneliness both individual and systemic, and what is the relationship between the two? What distinctive forms of loneliness are created by ableism, sanism, neoliberalism, capitalism, globalization, and the gig economy? Ought loneliness be avoided at all costs? What are the ethics of loneliness? In our introduction to this special issue, we unpack and theorize the potential perils and generative possibilities offered up by this profound emotion. Establishing a Feminist Loneliness Studies provides us with the space we need to begin addressing and comprehending loneliness.
