Loneliness in the Modern Age: An Evolutionary Theory of Loneliness (ETL)

Physical frailty in chilean older persons: The role of social relationships, multimorbidity, and mental health

AIMS

the objective of this study is to analyze the mediating role of loneliness, social isolation, and depressive symptoms in the relationship between multimorbidity and physical frailty among Chilean older adults living in the community, following the frailty model proposed by Gobbens.

METHODS

A total of 2132 older people were studied through a cross-sectional analysis of data from a population-based survey, using hierarchical linear regression and mediations with Hayes' method. Variables of Gobbens' model guided the data analysis.

RESULTS

Regression analysis revealed significant associations between physical frailty and age, education, self-perceived economic status, physical activity, social relationships, mental health, and multimorbidity. Mediation analysis confirmed that loneliness, social isolation, and depressive symptoms are partial mediators in the relationship between multimorbidity and frailty.

CONCLUSIONS

Multimorbidity contributes significantly to physical frailty. Loneliness and social isolation show weaker associations with frailty, whereas depressive symptoms have a more substantial mediating role. These results underscore the need to integrate these factors into frailty interventions for older people.

Perception of Loneliness in Adolescence: Role of Maladaptive Personality Traits and Trauma-Related Symptomatology

BACKGROUND/OBJECTIVES

Loneliness is a heterogeneous phenomenon, generally defined as an emotional experience based on the perceived distance between an individual's actual social relationships and those he or she would like to have. Adolescence is particularly vulnerable to loneliness because of the many changes in values, feelings, and emotions that characterize it. Among the aspects that may influence this feeling of discomfort, the literature identifies maladaptive personality and a dysfunctional response to traumatic events. Our study aims to identify the possible role that maladaptive personality traits and post-traumatic stress symptomatology in the form of Post-Traumatic Stress Disorder (PTSD) and Disturbance in Self-Organization (DSO) may play in the perception of loneliness in adolescents: Methods: We identified a mediation model constructed through structural equation modeling (SEM) to test PTSD and DSO post-traumatic stress symptomatology as independent variables and maladaptive personality as a mediator in the relationship between these and perceptions of loneliness in a population of adolescents of both sexes, Italian high school students; Results: Our study identifies the significant role of PTSD and DSO symptomatology in influencing the state of loneliness, both directly and indirectly through maladaptive personality traits, which appear to exert a substantial influence on the perception of loneliness, potentially functioning as mediators in the relationship between the latter and PTSD/DSO symptomatology. Presumably, a maladaptive personality may complicate recovery from adverse and traumatic experiences by preventing the implementation of functional coping strategies and promoting dysfunctional responses.

CONCLUSIONS

Our findings underscore the importance of researchers and clinicians adequately considering different personality traits and the early identification of post-traumatic stress symptomatology. A focus on adolescents' communication and interpersonal skills and their ability to respond effectively to stressful and traumatic events may prove useful in identifying more effective strategies for preventing and managing loneliness and related distress in adolescents.

Seeking Communal Emotions in Social Practices That Culturally Evolved to Evoke Emotions: Worship, Kitten Videos, Memorials, Narratives of Love, and More

In many instances, emotions do not simply happen to people by chance. Often, people actively seek out an emotion by engaging in practices that have culturally evolved to evoke that emotion. Such practices tend to be perpetuated and spread if people want to experience the emotion, like to recall it and tell others about it, want to give the emotion to others and experience it together, and/or regard the emotion as a sign of something wonderful. We illustrate this with a newly delineated emotion, kama muta. Many social practices around the world are structured to evoke kama muta. In those culturally evolved practices, and outside them, what typically evokes kama muta is a sudden intensification of communal sharing, or a sudden shift of attention to a communal sharing relationship. It seems probable that other social-relational emotions are also evoked by sudden changes in relationships or the sudden salience of a relationship. This change or saliencing may be incorporated in social practices that are perpetuated because they evoke the sought-after emotion. We suggest that such practices, as well as sudden changes in relationships that occur elsewhere, are especially promising places to discover social-relational emotions.

Lonely and Self-Centered? A Meta-Analysis of the Link Between Prosociality and Loneliness

While loneliness may motivate individuals to approach others, it may simultaneously increase their focus on self-preservation, resulting in egocentric behavior. Since the evidence linking loneliness and prosociality is inconclusive, the current meta-analysis aims to explore this relationship. Through a systematic search of databases, we identified 35 studies involving 44,764 participants. A small effect size for a negative correlation between loneliness and prosociality (r = -0.12, 95% CI: [-0.19, -0.05]) was found using the random effects model. The effect was not moderated by participants' sociodemographic characteristics or the WEIRDness of the sample but differed between types of measurement and forms of prosocial behavior. Our findings highlight the importance of understanding the processes perpetuating the link between loneliness and decreased prosociality, as this tendency may pose difficulties in restoring social connections, cooperating with others, or aiming for common goals.

Virtual friendly visitor program: combatting loneliness in community dwelling older adults

Introduction

Loneliness is a critical public health issue affecting older adults, with significant impacts on their mental and physical health, including increased risks of depression, cognitive decline, and higher mortality rates, necessitating distinct approaches for each condition given their unique implications and the exacerbation of these issues during the COVID-19 pandemic. We examine the implementation and outcomes of a Friendly Visitor Program (FVP) designed to mitigate loneliness among older adults. The program involved social work student interns providing virtual visits to older adults using computers and tablets, with the goal of enhancing social interaction and support.

Methods

The study utilized a qualitative narrative design for process evaluation and a longitudinal non-experimental, prospective research design for outcome evaluation, employing a three-level cross-classified longitudinal growth model to assess changes in loneliness among VFVP participants while also testing potential predictors of these changes.

Results

Findings indicated that the program was associated with reduced loneliness over time. Younger and White participants performed better in the program than older participants from other races and ethnicity. Satisfaction with visits and willingness to recommend the program were significant predictors of reduced loneliness. Unexpectedly, greater comfort with technology correlated with increased loneliness, suggesting overreliance on digital interactions may not substitute for in-person contact. Furthermore, improved social networks was associated with reduced loneliness, highlighting the importance of strong social networks.

Discussion

The study underscores the potential of friendly visitor interventions in addressing the challenges of lonely older adults and provides insights for optimizing such programs in the future.

Toward a National Profile of Loneliness in Old-Age China: Prevalence and Lonely Life Expectancy

OBJECTIVES

Loneliness presents a significant challenge for many older adults in China. Understanding the national scale and patterns of loneliness is critical to inform and guide policy interventions. This study builds a national profile of loneliness among Chinese adults aged 55 and above, illustrating the prevalence of loneliness and the average years expected to feel lonely, and examining how these measures vary by urban/rural residence and gender.

METHODS

This study uses the China Health and Retirement Longitudinal Study (2011-2018, N = 25,563) to estimate the loneliness prevalence across different gender and urban/rural residences. Drawing on Sullivan's method for calculating Healthy Life Expectancy, the author estimate the Lonely Life Expectancy (LLE), which quantifies the expected years an individual will live with loneliness.

RESULTS

Approximately 30% of older Chinese aged 55 and above reported experiencing loneliness during 2011-2018. At age 55, Chinese adults anticipate spending about 7-10 years feeling lonely, representing over one-third of their remaining lifespan. By age 75, this proportion may increase to more than half. Estimates of prevalence and LLE exhibit marked disparities with respect to gender and urban/rural residency. Rural women emerged as the most disadvantaged, facing the highest prevalence and largest proportion of remaining lifetime feeling lonely.

DISCUSSION

Older adults in China spend a significant proportion of their remaining lives feeling lonely. Marked disparities in LLEs underscore the potential role of loneliness in perpetuating health inequalities across different gender and urban/rural residences. These results highlight the urgent need for targeted interventions to mitigate the consequences of prolonged loneliness.

The Role of World Beliefs in Loneliness: Implications for Daily Social Interaction and Persistence of Loneliness Over Time

INTRODUCTION

Lonely people often crave social connection, but their social interactions fall short of fulfilling their needs. Although loneliness has been associated with negative views of the world, it is not clear whether these world beliefs contribute to the unfulfilling social interaction patterns that sustain loneliness. This research examined the role of world beliefs in explaining the effects of loneliness on daily frequency and quality of interaction, and the implications for sustained loneliness over time.

METHODS

Both members of romantic couples (N = 472) completed measures of loneliness, world beliefs, and daily social interactions with weak and strong ties over 2 weeks (daily N = 6411) and completed a follow-up assessment of loneliness a year later.

RESULTS

Relative to those who felt connected, lonely people believed the world was worse, dangerous, dull, and did not need them. Loneliness also indirectly predicted reduced quality and quantity of social interaction via negative, dull, and not needed world beliefs. In turn, the quality of interactions with strong ties predicted maintained loneliness a year later. However, dangerous world beliefs predicted better interactions with close relationship partners.

CONCLUSION

Findings suggest that the negative subjective worlds inhabited by lonely people may partially explain why lonely people have unfulfilling social interactions that tend to sustain their loneliness.

Loneliness Gets Under the Skin: A Scoping Review Exploring the Link Between Loneliness and Biological Measures of Inflammation

BACKGROUND

Research suggests that systemic inflammation may link loneliness to adverse health outcomes, yet there is a gap in comprehensively reviewing recent evidence on the relationship between loneliness and biological measures of inflammation in adults. This scoping review synthesizes current research to address the question: Is there a definitive link between loneliness and biological markers of inflammation in adults?

METHODS

Following the methods outlined by Arksey and O'Malley, we developed a protocol, defined our research question, and systematically searched PubMed, CINAHL, Embase, and Scopus for English-language studies conducted from 2018 to 2023 exploring the relationship between loneliness and biomarkers of inflammation in adults.

RESULTS

Twelve studies meeting the inclusion criteria displayed heterogeneity in terms of sample characteristics, loneliness scales, and inflammatory biomarkers. The UCLA Loneliness Scale, in various forms, emerged as the predominant tool for measuring loneliness, while C-reactive protein and interleukin-6 were the most frequently evaluated inflammatory biomarkers. Notably, all 12 studies reported an association between loneliness and at least 1 biological marker of inflammation.

CONCLUSION

Research consistently associates loneliness with poor health outcomes in aging adults, but the underlying mechanisms remain unclear. This scoping review suggests that inflammation may serve as a pathway linking loneliness to adverse health outcomes. However, the variability across studies highlights the need for standardized measurement methods and a consideration of both the duration and extent of loneliness. Enhancing our understanding of how loneliness affects systemic inflammation may help clarify why loneliness is associated with negative health outcomes.

Temporal associations of emotional and social loneliness and psychosocial functioning in emerging adulthood

Emerging adulthood is an important developmental phase often accompanied by peaks in loneliness, social anxiety, and depression. However, knowledge is lacking on how the relationships between emotional loneliness, social loneliness, social isolation, social anxiety and depression evolve over time. Gaining insight in these temporal relations is crucial for our understanding of how these problems arise and maintain each other across time. Young adults from a university sample (N = 1,357; M = 23.60 years, SD = 6.30) filled out questionnaires on emotional and social loneliness, social isolation, depressive and social anxiety symptoms at three time points within a 3-year period. Random intercept cross-lagged panel models were used to disentangle reciprocal and prospective associations of loneliness subtypes, social isolation, depressive and social anxiety symptoms across time. Results showed that on the within-person level, increases in emotional and social loneliness as well as social isolation predicted higher depression levels on later timepoints. Increases in depressive symptoms also predicted increases in subsequent social loneliness, but not in emotional loneliness. Finally, increases in depressive symptoms predicted increases in social isolation. There were no significant temporal relations between loneliness and social isolation on the one hand and social anxiety symptoms on the other hand. Social distancing imposed by COVID-19 related government restrictions may have impacted the current results. The findings suggest that emotional and social loneliness precede development of depressive symptoms, which in turn precedes development of social loneliness and social isolation, indicating a potential vicious cycle of social loneliness, social isolation and depressive symptoms in emerging adulthood. Social anxiety did not precede nor follow loneliness, depressive symptoms, or social isolation. The current study sheds more light on the temporal order of loneliness and psychopathological symptoms and hereby assists in identifying times where prevention and intervention efforts may be especially helpful to counter development of depression and loneliness.

The association of quality of life and fear of progression in patients with pulmonary hypertension: a cross-sectional network analysis

BACKGROUND

The quality of life (QoL) of patients with pulmonary hypertension (PH) is severely compromised. Fear of progression (FoP) may be an important predictor of compromising the QoL in PH patients. Therefore, our study aimed to investigate the association between QoL and FoP among PH patients.

METHODS

A cross-sectional study comprising 255 patients was conducted using convenience sampling, using the Self-administered socio-demographic information questionnaire, the World Health Organization quality of life questionnaire abbreviated version, and the Chinese version of the Fear of Progression Questionnaire-Short Form. Network analysis was completed using R software.

RESULTS

In the current network model, the QoL in the psychological domain had the highest node centrality (strength = 1.155). The highest bridge centrality node was physiological health-related fear (bridge strength = 0.303). The edge between physiological health-related fear and social family-related fear has the highest strength (edge weights = 0.596).

CONCLUSIONS

This study revealed that the psychological domain of QoL is likely to be the most dominant in the overall QoL of PH patients. It can serve as a primary focus for QoL management strategies to improve the overall QoL of PH patients. Furthermore, physical health-related fear is an urgent mental health concern to be alleviated in PH patients' FoP. As a bridge variable, physical health-related fear can be used as a potential clinical intervention target for developing and utilizing intervention programs to alleviate the FoP in PH patients, which may help maintain or even enhance the psychological and overall QoL of PH patients.

Social isolation and firearm secure storage in the USA: results from the 2022 BRFSS

BACKGROUND

Firearm secure storage (ie, storing firearms unloaded and locked) is recommended to reduce unintentional injuries and suicides. However, the relationship between psychological states, such as social isolation, and firearm secure storage practices is under-researched.

METHODS

Data are from 7136 individuals with firearms in their households from the 2022 Behavioral Risk Factor Surveillance System. Multinomial logistic regression was used to explore the relationship between social isolation and firearm storage.

RESULTS

Among respondents, 71.6% reported storing firearms unloaded, 14.2% stored firearms loaded and locked and 14.2% stored firearms loaded and unlocked. Most respondents reported feeling 'never' (40.7%) or 'rarely' (33.3%) socially isolated, with 18.7% reporting 'sometimes', 4.3% 'usually' and 3.0% 'always' feeling socially isolated. Covariate-adjusted multinomial logistic regression analysis revealed that respondents who felt 'always' socially isolated had an over threefold greater risk of storing firearms loaded and unlocked (relative risk ratio=3.733, 95% CI 1.443 to 9.662, p=0.007) compared with unloaded.

CONCLUSION

Results suggest a link between feelings of social isolation and unsecured firearm storage. Public health strategies should address both firearm safety education and the underlying issue of social isolation.

The Role of Insulin Within the Socio-Psycho-Biological Framework in Type 2 Diabetes-A Perspective from Psychoneuroimmunology

The interplay between socio-psychological factors and biological systems is pivotal in defining human health and disease, particularly in chronic non-communicable diseases. Recent advancements in psychoneuroimmunology and mitochondrial psychobiology have emphasized the significance of psychological factors as critical determinants of disease onset, progression, recurrence, and severity. These insights align with evolutionary biology, psychology, and psychiatry, highlighting the inherent social nature of humans. This study proposes a theory that expands insulin's role beyond traditional metabolic functions, incorporating it into the Mitochondrial Information Processing System (MIPS) and exploring it from an evolutionary medicine perspective to explore its function in processing psychological and social factors into biological responses. This narrative review comprises data from preclinical animal studies, longitudinal cohort studies, cross-sectional studies, machine learning analyses, and randomized controlled trials, and investigates the role of insulin in health and disease. The result is a proposal for a theoretical framework of insulin as a social substance within the socio-psycho-biological framework, emphasizing its extensive roles in health and disease. Type 2 Diabetes Mellitus (T2DM) with musculoskeletal disorders and neurodegeneration exemplifies this narrative. We suggest further research towards a comprehensive treatment protocol meeting evolutionary expectations, where incorporating psychosocial interventions plays an essential role. By supporting the concept of 'insulin resilience' and suggesting the use of heart rate variability to assess insulin resilience, we aim to provide an integrative approach to managing insulin levels and monitoring the effectiveness of interventions. This integrative strategy addresses broader socio-psychological factors, ultimately improving health outcomes for individuals with T2DM and musculoskeletal complications and neurodegeneration while providing new insights into the interplay between socio-psychological factors and biological systems in chronic diseases.

Contact with nature, nature prescriptions, and loneliness: Evidence from an international survey of adults in Australia, India, Singapore, the United Kingdom, and the United States

Evidence to support nature contact and nature prescriptions to reduce loneliness is scant. A total of 2100 individuals took part in a survey conducted in Australia (n = 525, mean age = 34.1), India (n = 526, mean age = 29.5), Singapore (n = 523, mean age = 36.1), the UK (n = 526, mean age = 37.3), and the US (n = 525, mean age = 43.6) in 2022 (overall age range 18-89yrs). Multilevel logistic regressions adjusted for confounding indicated mean levels of overall loneliness tended to be higher in India (Odds Ratio [OR] 1.21, 95% Confidence Interval [95%CI] 0.90-1.62), Singapore (OR = 1.54, 95%CI = 1.15-2.07), the UK (OR = 1.26, 95%CI = 0.96-1.67) and the US (OR = 1.24, 95%CI = 0.94-1.64) compared with Australia. Notable differences were observed by loneliness type, for example, with lower odds of social loneliness (OR = 0.57, 95%CI = 0.41-0.79) and higher odds of emotional loneliness (OR = 1.57, 95%CI = 1.14-2.06) in India compared with Australia. Findings with regards to loneliness and nature contact varied between country. In general, social loneliness was lower in participants who visited natural surroundings regularly (OR = 0.81, 95%CI = 0.61-0.98) and spent two hours or more per week in nature (OR = 0.65, 95%CI = 0.49-0.81). Overall loneliness (OR = 1.98, 95%CI = 1.48-2.47) and emotional loneliness (OR = 2.84, 95%CI = 2.13-3.51) were substantially higher among those who felt having no-one to go with was a barrier to spending time in nature. Emotional loneliness was higher in those who had more time in nature (OR = 1.32, 95%CI = 0.94-1.75) or more frequent visits (OR = 1.24, 95%CI = 0.94-1.49), which may be indicative of selective processes by which some people who feel emotionally lonely seek meaningful sources of connection or solace in natural environments. In sum, these findings highlight potentially important contingencies in how people feel lonely in different countries, and the potential of contact with nature as a means to address this critical issue of modern times. Randomised trials of nature prescription interventions for loneliness co-designed with respect to contrasting cultural, economic, and climatic contexts are needed to ensure programs intended to reconnect people with nature are effective, equitable, and acceptable for everyone.

Urbanization, loneliness and mental health model - A cross-sectional network analysis with a representative sample

With increasing urbanization, more people are exposed to mental health risk factors stemming from the urban social or physical environment. However, research on the relationship between urbanization and mental health is lacking. This cross-sectional study aimed to explore the relationships of the physical environment (spatial cohesion and urban environment) and social factors (neighborhood cohesion) with mental health (stress, anxiety and depression symptoms) and physical health and the mediating role of loneliness based on the proposed theoretical model. The study was conducted in Metropolis GZM (Silesia, Poland) in a representative sample of 3296 residents (48% women). The measurements used were the PSS-10, GAD-7, PHQ-9, R-UCLA3 and neighborhood cohesion scale. ANOVA results showed that city residents had better mental health indices than residents of villages and small towns. The network approach revealed that urbanization was one of the most influential nodes and played the role of a bridge between all other nodes. The model was confirmed and showed that the relationships between the physical environment and mental health were consecutively mediated by neighborhood cohesion and loneliness. Spatial cohesion related to factors of the physical environment and physical health, while physical health was directly connected to sociodemographic factors and weakly to stress. Anxiety was the strongest risk factor. Mental health can be improved by social and architectural factors, such as strengthening neighborhood cohesion and improving neglected buildings.

Efficacy of community groups as a social prescription for senior health-insights from a natural experiment during the COVID-19 lockdown

Loneliness and associated physical and cognitive health decline among the aging population is an important medical concern, exacerbated in times of abnormal isolation like the 2020-2021 Covid-19 pandemic lockdown. In this backdrop, recent "social prescribing" based health policy initiatives such as community groups as a support structure for the aging population assumes great importance. In this paper, we evaluate and quantify the impact of such social prescribing policies in combatting loneliness and related health degeneration of the aging population in times of abnormal isolation. To this end, we conduct a natural experiment across a sample of 618 individuals aged 65 and over with varying access to community groups during the Covid-19 lockdown period. Using a random-effects, probit model to compare the differences in health outcomes of participants with access to community groups (target) with those without access (control), we find that the target group was 2.65 times less likely to suffer from loneliness as compared to the control group, along with lower incidences of reported cardiovascular and cognitive health decline. These initial findings provide preliminary support in favor of the interventional power of social prescription tools in mitigating loneliness and its consequent negative health impact on the aging population.

Relationship between loneliness and post-traumatic growth in patients with gynecologic malignancies: the mediating role of self-disclosure and psychological resilience

BACKGROUND

To explore the relationship between loneliness and post-traumatic growth, with a focus on the mediating role of psychological resilience and self-disclosure.

METHODS

This study was a cross-sectional survey using the Loneliness Scale for Cancer Patients, the Distress Expression Index Scale (for measuring self-disclosure), the Psychological Resilience Scale, and the Posttraumatic Growth Scale on 215 inpatients with gynecologic malignancies at a tertiary care hospital in Guangzhou. Subsequently, Correlation, regression, and mediation analyses were performed using SPSS to test the relationships between the variables.

RESULTS

The results showed that loneliness was negatively correlated with posttraumatic growth (r = -0.261, P < 0.001), self-disclosure was positively correlated with posttraumatic growth (r = 0.360, P < 0.001), and psychological resilience was positively correlated with posttraumatic growth (r = 0.475, P < 0.001); loneliness was correlated with self-disclosure (r = -0.194, P < 0.01), loneliness was negatively correlated with psychological resilience (r = -0.287, P < 0.001), self-disclosure was correlated with psychological resilience (r = 0.287, P < 0.001); loneliness was significantly correlated with self-disclosure (r = -0.314, P < 0.001); loneliness was not a direct predictor of posttraumatic growth (β = -0.108, t = 1.734, P > 0.05), but could influence posttraumatic growth through the mediated effect of self-disclosure and psychological resilience, where the total indirect effect of self-disclosure and psychological resilience was - 0.155 (95% CI: -0.236, -0.081, P < 0.001).

CONCLUSIONS

The mechanism of loneliness on post-traumatic growth in patients with gynecologic malignancies is mainly through the indirect effect of self-disclosure and the indirect impact of psychological resilience. Great attention should be paid to patients' loneliness, to find factors promoting patients' self-disclosure, to improve the level of patients' psychological resilience, and promote post-traumatic growth of gynecologic malignant tumors.

The mediating effect of social connectedness between internet gaming disorder and somatic symptoms in adolescents: a large sample cross-sectional study

BACKGROUND

Previous studies have indicated that social connectedness can serve as a protective buffer against negative outcomes associated with online victimization. However, the role of social connectedness between Internet gaming disorder and somatic symptoms is still unclear. This study aims to examine the mediating effect of social connectedness on the association between Internet gaming disorder and somatic symptoms.

METHODS

A cross-sectional design was utilized, using questionnaires for data collection and multi-stage stratified cluster sampling. The general demographic questionnaire, Nine-Item Internet Gaming Disorder Scale-Short Form, Social Connectedness Scale-Revised and Patient Health Questionnaire Physical Symptoms were used to collect data. We adopted Pearson's correlation analysis and the PROCESS Macro Model in regression analysis to explore the relationships among Internet gaming disorder, social connectedness and somatic symptoms.

RESULTS

Internet gaming disorder was positively correlated with somatic symptoms (r = 0.20, P < 0.001), while network (r=-0.08, P < 0.001) and real-life social connectedness (r=-0.31, P < 0.001) negatively affected somatic symptoms. The network social connectedness and the real-life social connectedness played a chain mediating role in the development of Internet gaming disorder to somatic symptoms [95%CI: 0.073, 0.088], explaining 45.25% of the total effect value. The difference of real-life social connectedness and network social connectedness played a partial mediating role between Internet gaming disorder and somatic symptoms [95% CI:0.050, 0.062], accounting for 31.28% of the total effect value.

CONCLUSIONS

Real-life social connectedness, network social connectedness, and their disparity all mediated the relationship between Internet gaming disorder and somatic symptoms. Real-life social connectedness acted as a protective factor, while network social connectedness served as a risk factor. Encouraging offline activities and guiding teenagers to use the internet responsibly may help prevent and reduce physical symptoms linked to Internet gaming disorder.

Short-Term Coupling Associations Between State Loneliness and Cognitive Performance in Daily Life Among Older Adults

OBJECTIVES

Despite extensive efforts to study individual differences in loneliness and neurocognitive health, little is known about how within-person changes in state loneliness relate to cognitive performance. This study addressed this gap by examining the association between within-person variation in state loneliness and cognitive performance assessed objectively in daily life.

METHODS

Participants were 313 community-dwelling older adults (70-90 years) who reported momentary feelings of loneliness and completed smartphone-based cognitive tests 5 times daily for 14 consecutive days. Mobile cognitive tests assess visual associative memory, processing speed, and spatial memory.

RESULTS

At the day level, average state loneliness levels were negatively related to cognitive performance on the same day and subsequent day. Consistent with the day-level analysis, momentary assessments of increased loneliness were consistently linked to worse cognitive performance on concurrent assessments. However, moments characterized by lower cognitive performance predicted higher levels of loneliness 3-4 hr later (next occasion), but not vice versa.

DISCUSSION

The findings suggest a prospective association between loneliness and cognitive performance, with higher daily loneliness negatively associated with cognitive performance on the same day and predicting worse performance the following day. Notably, within a single day, lower cognitive performance at a given moment predicted elevated loneliness later in the day. This highlights a complex, reciprocal relationship-loneliness predicting and being predicted by cognitive performance depending on timescale.

A serial mediation model of sense of belonging to university and life satisfaction: The role of social loneliness and depression

The impact of a sense of belonging (SOB) on life satisfaction is acknowledged. However, research focusing on this dynamic within higher education is sparse. Additionally, the mechanisms underlying this association warrant further investigation. This study aimed to determine the serial mediation effects of loneliness and depression on the relationship between SOB and life satisfaction among college students. A cross-sectional survey was conducted with 345 college students (Mage = 22.16, SD = 4.48). The survey instruments included the Satisfaction with Life Scale (SWLS), the Social and Emotional Loneliness Scale for Adults (SELSA-S), the Depression, Anxiety, and Stress Scale (DASS), and the Institutional Integration Scale (IIS). The serial mediation effects were analyzed utilizing Model 6 of Hayes' PROCESS macro in SPSS. The results showed that the sense of belonging to the university had no direct effect on life satisfaction (Effect = 0.105, 95 % CI: -0.076 to 0.286). Loneliness and depression serially mediated the relationship between a sense of belonging to the university and life satisfaction (Effect = 0.029, 95 % CI: 0.012 to 0.051). Depression independently mediated the association between SOB and life satisfaction (Effect = 0.160, 95 % CI: 0.10 to 0.221), whereas loneliness did not serve as a significant independent mediator in the relationship between belonging to the university and life satisfaction (Effect = 0.014, 95 % CI: -0.006 to 0.039). This research enhances comprehension of the fundamental processes linking students' sense of belonging (SOB) with their life satisfaction, offering valuable perspectives for academic institutions to develop strategies to elevate university students' well-being.

Let me in: The neural correlates of inclusion motivation in loneliness

BACKGROUND

While it is well-established that humans possess an innate need for social belonging, the neural mechanisms underlying motivation for connection are still largely unknown. We propose that inclusion motivation - measured through the effort that individuals are willing to invest to be included in social interactions - may serve as one of the basic building blocks of social behavior and may change in lonely individuals.

METHODS

Following the screening of 303 participants, we scanned 30 low- and 28 high-loneliness individuals with functional magnetic resonance imaging while they performed the Active Inclusion Task (AIT). The AIT assesses the participants' levels of effort invested in influencing their inclusion during classic Cyberball conditions of fair play and exclusion.

RESULTS

High- compared to low-loneliness individuals showed higher urgency for inclusion, specifically during fair play, which correlated with higher activity in the right thalamus. Furthermore, in high-loneliness individuals, we found increased functional connectivity between the thalamus and the temporoparietal junction, putamen, and insula.

LIMITATIONS

Participants interacted with computerized avatars, reducing ecological validity. Additionally, although increasing inclusion in the task required action, the physical demand was not high. Additional limitations are discussed.

CONCLUSIONS

Inclusion motivation in loneliness is heightened during fair but not exclusionary interactions, and is linked to activity in brain regions implicated in appetitive behavior and social cognition. The findings indicate that lonely individuals may view threat in inclusionary interactions, prompting them to take action to regain connection. This suggests that inclusion motivation may help explain social difficulties in loneliness.

Loneliness and social isolation are not associated with executive functioning in a cross-sectional study of cognitively healthy older adults

The literature on the relationship between social interaction and executive functions (EF) in older age is mixed, perhaps stemming from differences in EF measures and the conceptualization/measurement of social interaction. We investigated the relationship between social interaction and EF in 102 cognitively unimpaired older adults (ages 65-90). Participants received an EF battery to measure working memory, inhibition, shifting, and global EF. We measured loneliness subjectively through survey and social isolation objectively through naturalistic observation. Loneliness was not significantly related to any EF measure (p-values = .13-.65), nor was social isolation (p-values = .11-.69). Bayes factors indicated moderate to extremely strong evidence (BF01 = 8.70 to BF01 = 119.49) in support of no relationship..   Overall, these findings suggest that, among cognitively healthy older adults, there may not be a robust cross-sectional relationship between EF and subjective loneliness or objective social isolation.

Reconsolidation of Traumatic Memories in the Treatment of Complex Post-traumatic Stress Disorder (CPTSD): A Case Study

This case study explores the memory reconsolidation-based technique of reconsolidation of traumatic memories (RTM) to address complex post-traumatic stress disorder (CPTSD). Using the framework of CPTSD and the components of International Trauma Questionnaire (ITQ), several presenting symptoms and the history of childhood trauma (adverse childhood experiences assessment) were assessed. The individual, based on the trauma-informed care approach, went through a total of eight sessions after the initial consultation that included RTM on index trauma events, reframing, and self-regulation techniques. CPTSD and several internalizing symptoms were measured before and after the intervention. The findings suggest that memory reconsolidation-based RTM protocol, coupled with the constructs of CPTSD using ITQ and index trauma, could provide benefits for individuals with symptoms from prolonged exposure to trauma during childhood.

Characterizing the momentary association between loneliness, depression, and social interactions: Insights from an ecological momentary assessment study

Evidence suggests that loneliness causes people to feel more depressed. It is unknown, however, why this association occurs and whether momentary versus chronic experiences of loneliness are implicated. Theoretical accounts suggest that momentary feelings of loneliness produce two competing motivations: social reaffiliation and social withdrawal. Social affiliation is protective against depression; social withdrawal, in contrast, is a risk factor. Thus, engaging in frequent and high-quality interactions following experiences of loneliness may protect against subsequent depression. We tested this hypothesis using a random-interval experience sampling design (5x/day/day, 14 days; Nobs = 6568) with a racially/ethnically diverse sample of adults with elevated depression symptoms (N = 102). Momentary loneliness was associated with depressed mood at the same time point and ∼2.5h and ∼5h later. Frequency and quality of social interaction did not moderate these associations. Findings suggest that momentary feelings of loneliness may be an important target for clinical intervention.

Within- and between-person associations between social interactions and loneliness: students' experiences during the COVID-19 pandemic

The COVID-19 pandemic introduced many restrictions to in-person interactions, and remote social interactions may be especially important for managing loneliness when such restrictions are in place. However, it is unclear how social interactions are related to loneliness when in-person interactions are limited. Data were collected between February 2021 and March 2022 from a sample of 581 university students. Participants reported their loneliness and participation in positive in-person or remote social interactions each day for 14 days. Results from dynamic structural equation models showed that participants felt less lonely than they usually felt on the days they engaged in positive remote interactions at the within-person level. Moreover, participants generally felt less lonely when engaging more frequently in remote interactions, but only when in-person interactions were restricted (between-person level). Some of these results varied by changing COVID-19 restrictions. Finally, for participants who felt lonelier in general, the effect of positive in-person and remote interactions on loneliness was less strong. These findings suggest that social interactions may buffer loneliness but are not as impactful for those who experience greater loneliness.

Time Perspective and Perceived Social Isolation: The Role of Social Interaction Anxiety

Time perspective is a theoretical construct that describes how humans perceive time, which can influence decision-making and subsequent behavior. Research has shown that an individual's dominant time perspective can be linked to increased risk of poor health. This study aimed to investigate the relationships between time perspective and perceived social isolation. Specifically, we examined the role of social interaction anxiety in the relationship between time perspective and perceived social isolation in a normative sample of college-aged individuals. Undergraduates (n = 1780) at a large midwestern university completed an online survey. Results revealed that future-oriented, past-positive, and present-hedonistic time perspectives were significantly negatively associated with perceived social isolation. In contrast, past-negative was positively associated with perceived social isolation, and these relationships were partially explained by social interaction anxiety. Understanding dominant time perspectives can help us to better assess health risk factors and may help to develop interventions to promote healthy behaviors.

Link workers' and clients' perspectives on how social prescribing offers a social cure for loneliness

Social prescribing is a healthcare model designed to reduce loneliness and improve individuals' health by addressing unmet social needs. The present study adopted the Social Cure framework to provide an understanding of the psychosocial processes involved in helping participants to engage with social activities, from both the link workers' and clients' perspectives. Semi-structured interviews were conducted with 15 link workers (Mage = 40.12; 87% female) and 15 clients (Mage = 55.33; 73% female, 7% non-binary) of social prescribing programmes across Australia and the transcripts were analysed using reflexive thematic analysis. Three overarching themes were identified: (1) Breaking Down Barriers, (2) Finding Fit with Others, and (3) Rebuilding a Sense of Self. These findings communicate how social prescribing addressed the psychosocial barriers of clients, and how joining groups that fostered positive shared social identities resulted in meaningful improvements to clients' well-being.

Bidirectional and Dynamic Relationships Between Social Isolation and Loneliness Among Older Adults in China

OBJECTIVES

This study aimed to investigate the bidirectional associations and temporal dynamics between social isolation (SI) and loneliness among older adults.

DESIGN

This is a prospective cohort study.

SETTING AND PARTICIPANTS

With the global phenomenon of population aging, there has been a significant increase in the prevalence of SI and loneliness among older adults. These factors exert substantial impacts on the health and well-being of this population. Consequently, it is imperative to implement more effective interventions targeting SI and combating loneliness in order to enhance the overall health and well-being of older adults.

METHODS

Data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were analyzed, focusing on individuals aged 65 and older. Generalized Cross-Lagged Modeling (GCLM) was used to assess these associations.

RESULTS

The findings reveal significant cross-lagged effects between SI and loneliness over the course of 16 years. Higher levels of SI at 1 time point predict increased loneliness scores in subsequent periods, and greater levels of loneliness at 1 time point predict higher SI scores in future periods. Notably, the impact of SI on loneliness is found to be larger and more enduring compared to the influence of loneliness on SI. These cross-lagged effects persist over an extended period, indicating a long-term reciprocal relationship between SI and loneliness among older adults.

CONCLUSIONS AND IMPLICATIONS

This study provides valuable insights into the bidirectional associations between SI and loneliness among older adults. Given that the effect of SI dominates, the findings suggest that public health strategies aimed at promoting health and well-being should prioritize interventions that enrich older adults' social networks. Emphasizing early interventions aimed at enhancing social networks is essential for promoting healthy aging and overall well-being.

Offender Rehabilitation: The Middle Way of Maimonides to Mental and Social Health

Traditional religious and spiritual texts offer a surprising wealth of relevant theoretical and practical knowledge about human behavior. This wellspring may contribute significantly to expanding our current body of knowledge in the social sciences, and criminology in particular. In Jewish religious texts, specifically by Maimonides, we can find profound analyses of human traits and guidelines for a normative way of life. Among other things, modern criminological literature attempts to link certain character traits and divergent behaviors. Using the hermeneutic phenomenological approach, this present study analyzed Maimonidean writings, mainly Laws of Human Dispositions, in order to understand Moses ben Maimon (1138-1204) and his view of character traits. The analysis yielded four themes: (1) Human personality between nature and nurture; (2) The complexity of human personality, imbalance and criminality; (3) Extremism as a way to achieve balance; and (4) The Middle Way, flexibility and common sense. These themes can serve therapeutic purposes, as well as inform a rehabilitation model. Grounded in a theoretical rationale about the nature of humans, this model is designed to direct individuals to balance their traits by self-reflection and constant practice of the Middle Way. The article concludes by proposing that implementing this model may promote normative behavior and thus contribute to rehabilitating offenders.

Association of perceived inequality, relative deprivation and loneliness with the trajectory of anger in university students

OBJECTIVE

To examine the trajectory of anger and its psychosocial predictors (i.e., perceived social inequality, relative deprivation, and loneliness) as well as its association with anxiety and depression.

PARTICIPANTS/METHOD

Students (N = 365) completed an online survey three times over a one-year period.

RESULTS

Three trajectories of anger were identified by growth mixture modeling: low/stable (i.e., a low and stable anger over time; 88.0%), low/increasing (i.e., a low level of anger with an increasing trend; 6.7%), and moderate/decreasing class (i.e., a moderate level of anger with a decreasing trend; 5.3%). A greater perception of relative deprivation, but not of perceived social inequality, was associated with the low/increasing class. A greater level of loneliness was associated with the moderate/decreasing class. Symptoms of depression and anxiety were higher in the moderate/decreasing and low/increasing class than in the low/stable class.

CONCLUSIONS

These results suggest that interventions targeted at anger may benefit from addressing perceptions of relative deprivation and loneliness.

Longitudinal cross-lagged analysis of depression, loneliness, and quality of life in 12 European countries

BACKGROUND

In the older population, depression, loneliness, and quality of life are closely related, significantly influencing health status. This paper aimed (1) to investigate autoregressive and cross-lagged associations over 2 years between depression, loneliness, and quality of life, and (2) to examine sex-related differences in the 2-year associations between depression, loneliness, and quality of life in a large sample of European citizens aged ≥ 50 years.

METHODS

This is a longitudinal analysis. We included 7.456 individuals (70.89 ± 7.64 years; (4.268 females) who responded to waves 7 (2017) and 8 (2019) of the SHARE project. The variables analyzed in both waves were depression, loneliness, and quality of life.

RESULTS

Comparatively, females indicated higher depression and loneliness scores than males and a lower perception of quality of life. Autoregressive associations pointed that past depression, loneliness, and quality of life predicted their future episodes 2 years later (p < 0.001). The cross-lagged analysis of males showed positive and significant bidirectional associations between depression and loneliness 2 years later. Females also showed a positive and significant association between depression and loneliness, but loneliness was not associated with depression 2 years later. In turn, previous high levels of quality of life had a protective role in late depression and loneliness up to 2 years.

CONCLUSIONS

This study highlighted the need to simultaneously assess and manage depression, loneliness, and quality of life in the older European population. It is suggested that sex-specific policies can be created, including social support, in order to reduce depression and loneliness, and promote quality of life.

Interpersonal Loneliness Predicts the Frequency and Intensity of Nightmares: An Examination of Theoretic Mechanisms

The evolutionary theory of loneliness (ETL) argues that human belongingness is essential to survival and failing to meet belongingness needs constitutes a threat to viability. In two separate studies (total N = 1,609), links between loneliness and nightmares were examined as a test of ETL postulates. As hypothesized, loneliness predicted nightmare frequency (both studies) and nightmare intensity (Study Two only). Although stress mediated the relationship between loneliness and nightmare frequency in Study One, stress was not a significant mediator of this relationship in Study Two. As predicted, in Study Two both hyperarousal and rumination mediated the relationships between loneliness and nightmare frequency and between loneliness and nightmare intensity. Theoretical implications include support for both the aversive signaling and implicit vigilance postulates of ETL.

Evaluation of the effects of pandemic-related fears on anxiety and depression: the mediating roles of traumatic stress and loneliness

BACKGROUND

The detrimental mental health effects which emerged from COVID-19 have profoundly affected healthcare workers (HCWs) worldwide. The aim of this study was to investigate the mediating effects of traumatic stress and loneliness on the fears of contracting and dying from COVID-19, and anxiety and depression of HCWs during the pandemic.

METHODS

A cross-sectional online survey was completed by HCWs in a province of Turkey. The Hospital Anxiety Depression Scale, Impact of Events Scale-Revised and numerical rating scales (for fears of COVID-19 and loneliness) were used and a bootstrap approach was used in the analyses with SPSS PROCESS macro software.

RESULTS

Of the HCWs evaluated, 150 (34.4%) were doctors, with a mean duration of work experience of 10.6 ± 7.5 years. The results indicated that fear of contracting COVID-19 was directly related to anxiety (β = 0.244, p < 0.001) and depression (β = 0.135, p < 0.01) and that traumatic stress and loneliness mediated the relationships between the fear of contracting COVID-19 and anxiety (β = 0.435, p < 0.001; β = 0.235, p < 0.001, respectively) and depression (β = 0.365, p < 0.001; β = 0.294, p < 0.001, respectively). The fear of dying from COVID-19 was determined to be directly associated with anxiety (β = 0.190, p < 0.001) but not with depression (β = 0.066, p = 0.116), and traumatic stress and loneliness mediated the relationships between the fear of dying from COVID-19 and anxiety (β = 0.476, p < 0.001; β = 0.259, p < 0.001, respectively) and depression (β = 0.400, p < 0.001; β = 0.311, p < 0.001, respectively).

CONCLUSIONS

The study results demonstrated the important roles of traumatic stress and loneliness in exacerbating the negative consequences of fears of COVID-19 on anxiety and depression, and provide insights for identifying HCWs at greater risk.

Why So Lonely? The Direct and Indirect Associations between Developmental Trajectories of Fear of Negative Evaluation, Prosocial Behavior and Loneliness in Adolescence

Fear of negative evaluation and prosocial behavior have been identified as predictive factors influencing the development of loneliness in adolescence, representing typical factors in the cognitive and behavioral processes of re-affiliation. The elucidation of plausible direct and indirect pathways linking these pivotal factors to adolescents' loneliness need further exploration. This study aimed to investigate the direct and indirect relationships between the fear of negative evaluation, prosocial behavior, and adolescents' loneliness through the lens of developmental changes. A total of 533 adolescents (49.0% girls, Mage = 15.18 years, SD = 0.71) participated in this longitudinal study, assessed at three timepoints over a span of two years with 12-month intervals. Latent growth modeling uncovered direct associations between the developmental trajectories of both fear of negative evaluation and prosocial behavior with the developmental trajectory of adolescents' loneliness. The developmental trajectory of fear of negative evaluation exhibited an indirect association with the developmental trajectory of loneliness through the mediating role of prosocial behavior. These findings highlighted the roles of cognitive and behavioral re-affiliation processes, both independently and as mediators, in influencing adolescent loneliness, suggesting that interventions aimed at reducing fear of negative evaluation and promoting prosocial behavior could effectively mitigate adolescents' loneliness.

Silence between words: Is solitude important for relatedness?

Chronic loneliness is a risk factor for physical and health problems, in part due to dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system. In contrast, temporary moments of positive solitude (passing good times alone and not feeling lonely) appear to have positive effects on mental health, social life, and creativity, and seems to be a buffer against loneliness. Herein, three ways of how solitude may have positive effects on health and relatedness are discussed, namely effects on enhancement of mind-wandering, interoceptive awareness, and spirituality. Solitude may facilitate (1) activation of the default mode network (DMN) underlying mind-wandering including daydreaming about other people; (2) activation of brain areas supporting interoceptive awareness; (3) deactivation of prefrontal cortex, or deactivation and decreased connectivity of the DMN, giving raise to susceptibility to spiritual experiences. The capacity to handle and enjoy solitude is a developmental process that may be difficult for many persons. Craving for social connections and external stimulation with digital technologies (e.g., internet, smartphones, social media) might be interfering with the development of the capacity for solitude and thereby increasing loneliness; this might be partly due to impaired interoceptive awareness and impaired functional mind-wandering (common in solitude). Congruently, overuse of digital technologies was associated with reduced activity, and reduced gray matter volume and density, in brain areas supporting interoceptive awareness, as well as with decreased connectivity of the DMN supporting creative insights. Solitude has been a relatively dismissed topic in neuroscience and health sciences, but a growing number of studies is highlighting its importance for well-being.

Investigating the relationship between early cardiovascular disease markers and loneliness in young adults

Loneliness is recognised as a risk factor for cardiovascular disease development. However, it is unclear whether loneliness itself or other closely related mental health symptoms, such as depression and social anxiety, are associated with the development of cardiovascular disease. In the present study, we examined the relationship between loneliness and several early cardiovascular disease markers in young adults, after controlling for depression and social anxiety. Sixty-six young adults (18-35 years old, Mage = 22.70; 75.8% females) completed psychological questionnaires and took part in several physiological tests assessing cardiovascular health (e.g., vascular function). Results revealed higher loneliness was significantly associated with shorter pulse transit time (β = - 0.70, p = 0.002; shorter pulse transit time is a subclinical marker for arterial stiffness). Additionally, results show that while loneliness and depression were both related to vascular dysfunction in young adults, the underlining physiological mechanisms through which they affect vascular function may be different. Specifically, higher loneliness was associated with increased arterial stiffness, whereas depression was associated with increased endothelial dysfunction (β = - 0.43, p = 0.04). Our findings indicate that presence of loneliness and depression in young adults may be accompanied by early indicators of poor cardiovascular health, such as arterial stiffness and endothelial dysfunction. Results from the study further support the link between loneliness and cardiovascular disease development.

Age and Gender Identity in the Relationship Between Minority Stress and Loneliness: A Global Sample of Sexual and Gender Minority Adults

Loneliness is prevalent among sexual minority adults and is associated with minority stress. Yet there is limited understanding of how loneliness and minority stress vary across key demographic variables. This cross-sectional study explored age and gender differences in a minority stress model linking sexual orientation marginalization to social and emotional loneliness via proximal stress (internalized homonegativity, concealment, and stigma preoccupation) and via social anxiety and inhibition. The study also assessed age and gender differences in the protective influence of LGBTQ community involvement. 7,856 sexual minority adults from 85 countries completed an online survey. They were categorized as emerging adults (18-24, n = 3,056), young adults (25-34, n = 2,193), midlife adults (35-49, n = 1,243), and older adults (50-88, n = 1,364). Gender identity groups were cisgender men (n = 4,073), cisgender women (n = 3,017), and transgender individuals (n = 766). With each successive age group, there was a lower prevalence of sexual orientation marginalization, proximal stress, social anxiety, inhibition, and emotional loneliness, along with more community involvement. Sexual orientation marginalization was more pronounced among cisgender women and, especially, transgender individuals. The latter also exhibited the most social anxiety, inhibition, loneliness, and community involvement. Proximal stress was more prevalent among cisgender men than cisgender women and transgender individuals. Multiple group structural equation modeling supported the applicability of the loneliness model across age and gender groups, with only a few variations; these mainly related to how strongly community involvement was linked to marginalization, internalized homonegativity, and social loneliness.

College students' daily mind wandering is related to lower social well-being

Objective: This study sought to examine how daily mind wandering is related to loneliness, felt connection to others, and school belonging among college students. Participants: Three samples (n = 209, n = 173, and n = 266) from two US campuses were recruited. Methods: Data were collected via ecological momentary assessment over the course of two academic quarters in one sample and an academic semester in two samples. Results: Social well-being declined throughout the academic term in all samples. Lower day-to-day mind wandering predicted lower loneliness at the next time point and was concurrently related to a higher felt connection to others and higher school belonging. Thoughts about the past and future were associated with lower social well-being than present-focused thoughts. Conclusions: This study supports the proposition that promoting present-centered attention can benefit college students' social well-being and alleviate their feelings of loneliness and isolation that they often experience.

The study of female college students' consumer psychology mechanism toward male celebrity endorsed products: Tempted or coerced?

The trend of male celebrities endorsing female products is increasing. However, research is lacking on whether this influence is due to the positive emotions generated by the male celebrity's attractiveness or the peer pressure due to mass purchases by the celebrity's fans, and how these effects differ across products with different attributes. This study aims to fill the gap in the existing literature by investigating the influence of male endorsers on female consumers purchase intention, and to deepen the understanding of the mechanisms by which attractiveness and conformity jointly influence purchase decisions. This study used a mixed-design text experiment to investigate the impact of male endorsers' attractiveness and conformity on female college students' positive product attitude and purchase intention for gender-neutral product, female skincare product, and female intimate product, based on the Theory of Planned Behaviour (TPB). The data collected from 456 female college students were analyzed using bootstrap analysis. The study found that both male endorsers' attractiveness and conformity can enhance female college students' positive product attitude and promote their purchase intention for gender-neutral product. However, for female skincare product, male endorsers' attractiveness affects their positive product attitude and purchase intention. Nevertheless, when conformity was present, attractiveness no longer had an effect. Furthermore, for individuals with high levels of loneliness, attractiveness had a detrimental effect on their positive product attitude. On the other hand, conformity had a positive effect by promoting positive product attitude and increasing purchase intention. For female's intimate product, attractiveness did not affect positive product attitude and purchase intention, but the positive effect of conformity remained significant, and both relationships were not moderated by loneliness. It enhances our comprehension of the intricate dynamics underlying the influence of male celebrity endorsements on consumer purchasing decisions, and also offers theoretical justification for the selection of male endorsers for diverse female product.

Threatened by others or by everything? The effects of momentary and trait loneliness on daily appraisals of social company and being alone in young adults

Theoretical accounts of loneliness suggest that it may lead to psychopathological consequences by increasing the perception of social threat. However, it is unclear whether the real-life effects of both trait and state loneliness are specific to social situations. To answer this question, two experience sampling studies were conducted with prestratified samples of young adults (18-35) with moderate (Study 1, N = 64) or low and high (Study 2, N = 103) levels of loneliness. Participants were asked to report their emotional states and appraisals of social and nonsocial situations. Multilevel modelling of momentary and time-lagged associations revealed that trait loneliness was associated with less positive (Study 1) and more negative (Study 2) company appraisals. Importantly, in Study 2, trait loneliness was also related to less positive and more negative appraisals of being alone. Momentary loneliness was related to less positive and more negative appraisals of both types and predicted negative social appraisals over time in both studies. In Study 2, time-lagged interaction effects on social appraisals were found between the two levels. The results suggest that in highly lonely individuals, both levels of loneliness may lead to a general negativity bias and have a synergistic effect.

Predictive factors and risk and protection groups for loneliness in older adults: a population-based study

BACKGROUND

Loneliness is considered a public health problem, particularly among older adults. Although risk factors for loneliness have been studied extensively, fewer studies have focused on the protected and risk groups that these factors configure. Our objective is to analyze the variables and latent factors that predict loneliness in older adults and that enable risk and protected groups to be configured.

METHODS

We employed an epidemiological, cross-sectional survey that was carried out on a random sample of 2060 people over 65 years extracted from the census. A structured telephone interview was used to assess mental and physical health, habits, quality of life, and loneliness, applying the COOP-Wonca, Goldberg General Health (GHQ-12), and Barber Questionnaires.

RESULTS

Predictors of loneliness were: mental health, living alone, quality of life, depressive symptoms, low educational level, and some deficiency situations such as having no one to turn to for help. The factors extracted (Factorial Analysis) were: a subjective experience of poor health, objective isolation, and psychological isolation. We established at risk and protected groups ("Decision Tree" procedure), and loneliness was referred to by 73.2% of the people living alone and with poor mental health and quality of life (risk group). By contrast, only 0.8% of people living with others, with good mental health and good quality of life felt loneliness (protected group).

CONCLUSION

In a well-developed city, subjective and objective factors are associated with loneliness. These factors, especially those associated with at risk or protected groups, must be considered to develop strategies that address loneliness.

Chronic and Transient Loneliness in Western Countries: Risk Factors and Association With Depression. A 2-Year Follow-Up Study

INTRODUCTION

Our aim was to test risk factors for chronic and transient loneliness as well as cross-sectional and longitudinal associations of courses of loneliness with depression.

METHODS

Responses from participants in Wave 5 (T1, 2013) and Wave 6 (T2, 2015) of The Survey of Health, Ageing and Retirement in Europe (SHARE) (N = 45,490) were analyzed. The existence of clinically significant symptoms of depression was defined as reporting a value greater than or equal to 4 on the Euro-D scale. Loneliness was measured through the 3-item UCLA loneliness scale and a single question. Both measures were tested in separate regression models to identify risk factors for transient (loneliness at T1) and chronic (loneliness at T1 and T2) loneliness as well as their associations with depression.

RESULTS

Chronic loneliness was observed in 47%-40% of the cases of loneliness, according to the UCLA scale and the single question, respectively. Risk factors for chronic loneliness in both models were being female, not being married, having a low educational level, having poor mental and physical health, being limited in activities, having a poor social network, and living in a culturally individualistic country. Risk factors for transient loneliness were less robust and no significant effects were found for variables such as sex and physical health in both models, education level in the UCLA measure model, and social network size in the single question model. Chronic loneliness also showed a strong association with depression in the cross-sectional model and a marked one in the longitudinal model.

CONCLUSION

The courses of loneliness are relevant in the study of its risk factors and association with depression.

Bidirectional Relationships and Mediating Effects Between Social Isolation, Loneliness, and Frailty in Chinese Older Adults

Background and Objectives

Social isolation (SI) and loneliness are key factors that contribute to frailty among older adults. Current estimates regarding how frailty affects SI and loneliness and how SI and loneliness affect frailty may be flawed due to reverse causality. This study aimed to investigate the bidirectional relationships and mediating effects among SI, loneliness, and frailty among older adults in China.

Research Design and Methods

The study analyzed data from 6 waves of the Chinese Longitudinal Healthy Longevity Survey conducted between 2002 and 2018. The sample included individuals aged 65 and older. The General Cross-Lagged Panel Model was used to account for confounding factors and reveal mediating effects.

Results

Our findings specifically indicate a direct effect of SI on frailty, although suggesting that loneliness may indirectly affect frailty through its influence on SI. Additionally, frailty can lead to increased SI and loneliness.

Discussion and Implications

SI and loneliness are strongly intertwined with frailty among older adults in China. To prevent the development of frailty, public health initiatives should prioritize reducing SI among older adults. Furthermore, efforts to decrease frailty levels can yield positive outcomes by mitigating both SI and loneliness among this population.

Social anxiety and loneliness among older adults: a moderated mediation model

BACKGROUND

Few studies have clarified the mechanisms linking social anxiety and loneliness in older populations. The study aimed to explore how social network mediate the relationship between social anxiety and loneliness in older adults, with perceived social support playing a moderating role.

METHODS

A total of 454 older patients completed the Social Avoidance and Distress Scale, Lubben Social Network Scale-6, Chinese version of the Short Loneliness Scale and Perceived Social Support Scale. Bootstrap and simple slope methods were used to test the moderated mediation model.

RESULTS

Social anxiety had a significant positive predictive effect on loneliness and social network partially mediated this relationship. The relationship between social anxiety and social network, as well as the relationship between social network and loneliness, was moderated by perceived social support. Specifically, perceived social support buffered the effects of social anxiety on social network, but the buffering effect diminished with increasing levels of social anxiety. On the social network and loneliness pathway, the social network of older persons with higher perceived social support has a stronger prediction of loneliness.

CONCLUSIONS

The study found that social anxiety can contribute to loneliness by narrowing older adults' social network. High perceived social support can buffer this process, but do not overstate its protective effects. Thus, interventions to reduce social anxiety and improve social network and social support may help prevent and alleviate loneliness in older adults.

Profiles of Loneliness and Ostracism During Adolescence: Consequences, Antecedents, and Protective Factors

This longitudinal study (N = 1078, 46% boys; 54% girls) examined profiles of loneliness and ostracism during adolescence and their consequences and antecedents. Longitudinal latent profiles analyses identified four distinct profiles: (1) High emotional loneliness (25%), High and increasing social loneliness (15%), High peer exclusion and high social impact (9%) and No peer problems (51%). Subsequent internalizing problems were typical for the High and increasing social loneliness profile and externalizing problems for the High emotional loneliness and High peer exclusion and high social impact profiles. Furthermore, effortful control, prosocial skills, and relationship quality with parents and teachers were highest in the No peer problems profile, whereas the High and increasing social loneliness profile had the lowest self-esteem and was characterized by low surgency/extraversion, high affiliativeness, and high negative affectivity.

Older men and loneliness: a cross-sectional study of sex differences in the English Longitudinal Study of Ageing

BACKGROUND

Research into men and masculinities suggests men may be more reluctant than women to state they are lonely, more reliant on partners/spouses and/or alcohol to tackle it, and that this may be a result of poorer social relationships. Ageing is often associated with loneliness, and research has indicated gendered results in older people, but existing evidence lacks generalisability and cultural context. This study tests hypotheses on sex differences in loneliness in older England-based men and women.

METHODS

We conducted a cross-sectional study using a sample of 6936 respondents aged 50 + from the English Longitudinal Study of Ageing (wave 8). Multiple imputation with chained equations was conducted to handle missing data. Multivariate regression was used to investigate the impact of sex on a direct question on loneliness whilst controlling for the University of California loneliness (UCLA) scale. Multivariate regression with interaction terms were used to examine sex differences in loneliness and alcohol consumption, partner status, and social relationships.

RESULTS

Older men were less likely than older women to state they are lonely even when controlling for UCLA score. Older men showed a greater association between loneliness and alcohol consumption, but only when measuring the number of units consumed in the last week, and not using a less precise measure of the past year. Older men who cohabited with a partner were less lonely than cohabiting older women, whereas previously married but not cohabiting older men were lonelier than their female counterparts. However, never married older men were less lonely than never married older women. Evidence was found to suggests older men's worse friendships mediated this association, but social isolation and number of close relationships did not. Severe isolation predicted greater loneliness in older women, but not older men.

CONCLUSIONS

Cultural ideals of masculinity and older men's poorer quality friendships may explain their reluctance to directly state loneliness, greater dependency on partners/spouses, and use of alcohol. Severely isolated older men may under-report loneliness on the UCLA scale as well as a direct question.

The association between social isolation, loneliness and psychological problems in young adults: A study during the acute phase of COVID-19 in Italy

During the COVID-19 pandemic, governments had to impose social isolation measures to safeguard the citizens' health. However, this could have affected psychological problems. The aim of the present study was to investigate the psychological effects associated with social and emotional isolation during the acute phase of the COVID-19 in Italy. To this purpose, the degree of social isolation and loneliness and the presence of psychological problems (externalising and internalising) were investigated online in a sample of 395 young adults (18-30 years; 57% women). Results confirmed the relevant association between social isolation, loneliness and psychological problems, in both internalising and externalising dimensions. Particularly, loneliness showed the strongest association. Moreover, consistently with surveys conducted during the COVID-19-era, data highlighted that men were more vulnerable to social isolation and loneliness than women. These results underline the need for adequate interpersonal support during moments of isolation to prevent negative effects on psychological problems.

Exploring the relationship between loneliness and volunteering amongst Australian adults: a cross-sectional study

BACKGROUND

Alleviating loneliness and fostering social connections and a sense of belonging are essential for individuals' well-being in the aftermath of the COVID-19 pandemic. Volunteering has emerged as a potential strategy to prevent or alleviate loneliness among adults. To gain insights into factors that can reduce or protect against loneliness, it is important to consider multi-dimensional measures of loneliness and motivations to volunteer. This study aimed to understand which variables predict Australian volunteers' social, family, and romantic loneliness.

METHODS

From October 2021 to January 2022, a cross-sectional online survey was administered to a sample of Australian adults with volunteering experience. The survey collected demographic information and used validated measures to assess social, family, and romantic loneliness and volunteer motivation. Bivariate and multivariate analyses were conducted to examine the association between loneliness and motivations for volunteering.

RESULTS

Of the 1723 individuals who accessed the survey link, 160 participants completed the survey. The average age of respondents was 59.87 years (SD 12.3). The majority were female (77.5%), married or partnered (70.6%), and had ten or more years of volunteering experience (62.1%). Overall, participants reported low to moderate levels of loneliness across social (M = 12.1; SD = 5.3), family (M = 11.3; SD = 6.7), and romantic (M = 14.8; SD = 8.3) dimensions. Social motivation for volunteering was negatively associated with social and romantic loneliness, while enhancement and protective motivations were positively associated with family and romantic loneliness. Age and rurality were not significantly associated with any dimension of loneliness.

CONCLUSIONS

Loneliness is a multifaceted and intricate experience that impacts individuals socially and emotionally. This study's findings confirmed that having protective and enhancement motives to volunteer was associated with increased loneliness. Social motives to volunteer were associated with a tendency to have lower levels of loneliness, possibly due to the positive impact of building and maintaining social relationships through volunteering. Understanding these associations is necessary to ensure that volunteering activities align with each person's unique needs and motivations.

Impaired sleep, multimorbidity, and self-rated health among Canadians: Findings from a nationally representative survey

Background

Self-rated health (SRH) is a globally recognized measure of health status. Both impaired sleep (IS) and the presence of multimorbidity are related to poorer SRH, but the precise nature of these associations remains unclear. This study explored the association between IS, multimorbidity, and SRH among Canadian adults.

Method

We used 2017-18 Canadian Community Health Survey (CCHS) data for this study. The main variable of interest, self-rated health (SRH), measured participants' health on a 5-point Likert scale, later categorized as "good or better" vs. "fair or poor". The primary predictor, IS, was derived from two variables and categorized into four groups: no sleep issues; fewer sleeping hours (<7 hours) only; trouble sleeping only; and fewer hours & trouble sleeping. Multimorbidity was present (yes/no) if a participant indicated being diagnosed with two or more chronic conditions.

Results

Just over one in ten Canadians reported fair/poor SRH and approximately one-quarter had multimorbidity or experienced few sleep hours in combination with trouble sleeping. The adjusted model indicated greater odds of fair/poor SRH associated with the 40-64 years age group, male sex, and lower socio-economic status. It also suggested the presence of multimorbidity (AOR= 4.63, 95% CI: 4.06-5.28) and a combination of fewer sleep hours and troubled sleep (AOR= 4.05, 95% CI: 2.86-5.74) is responsible for poor SRH. Forty-four percent of the total effect of IS on SRH was mediated by multimorbidity.

Conclusion

This unique finding highlights the mediating role of multimorbidity, emphasizing the importance of addressing it alongside sleep issues for optimal health outcomes.

Exploring the relationship between perceived loneliness and subjective cognitive decline in older individuals

OBJECTIVE

Loneliness has been associated to a greater risk of cognitive decline and dementia in older individuals. However, evidence on whether this association also exists for older individuals who complain of cognitive problems is limited. We conducted a survey to examine the association between subjective cognitive decline in the working memory domain, perceived loneliness, depression, anxiety, and stress in older individuals with different profiles.

METHODS

A total of 302 healthy, old individuals completed 3 questionnaires to assess subjective cognitive problems in attention, executive functions, storage, depression, anxiety, stress, and perceived loneliness.

RESULTS

We conducted a cluster analysis and 3 clusters of individuals with different profiles emerged. Individuals with greater subjective cognitive problems (cluster 1) in the attention and storage domains, reported higher perceived loneliness and stress but not depression. In contrast, individuals with the least subjective cognitive problems (cluster 3) in the storage domain, reported lower perceived loneliness.

CONCLUSIONS

Individuals with higher subjective cognitive decline also report higher levels of perceived loneliness but not more depression than their peers. However, this correlation is present only for individuals with mild subjective cognitive decline (cluster 2). The implications for future research and interventions are discussed.

Deepening Depression in Women Balancing Work-Life Responsibilities and Caregiving during the COVID-19 Pandemic: Findings from Gender-Specific Face-to-Face Street Interviews Conducted in Italy

PURPOSE

This study investigated the impact of the COVID-19 pandemic on mental health, quality of life, and family functioning in a sample of the general female population, exploring difficulties encountered in managing family and work responsibilities and burden of care when taking care of a loved one. This study was, moreover, aimed at investigating factors capable of influencing severe depressive symptomatology in the context of socio-demographics, traumatic events, individual vulnerability, and family functioning.

METHOD

The sampling method used in this research was non-probability sampling. The survey took place during a Hospital Open Weekend (8-10 October 2021) organized by the National Gender Observatory on Women's Health "Fondazione Onda" on the occasion of the World Mental Health Day.

RESULTS

A total of 211 women were interviewed (mean age = 35.6, 53% living alone, more than 15% with financial difficulties, 47% exposed to the 2009 L'Aquila earthquake). More than 50% of the sample reported a higher complexity in managing their lives during the COVID-19 pandemic compared to their previous routine, with no statistically significant differences between working women and non-workers, although the latter obtained higher scores for depressive symptomatology and poorer quality of life. Compared to non-caregivers, female caregivers (22.3%) in charge of the care of loved ones affected by physical (10.9%) or psychiatric disabilities (11.4%) complained of a poorer quality of life, especially in general health perception (p = 0.002), physical function (p = 0.011), role limitations related to physical problems (p = 0.017), bodily pain (p = 0.015), mental health (p = 0.004), and social functioning (p = 0.007). Women caring for people affected by mental disorders seemed to experience a more significant worsening in vitality (p = 0.003) and social functioning (p = 0.005). Approximately 20% of the total sample reported severe depressive symptomatology. Previous access to mental health services (O.R. 10.923; p = 0.000), a low level of education (O.R. 5.410; p = 0.021), and difficulties in management of everyday lives during the COVID-19 pandemic (O.R. 3.598; p = 0.045) were found to be the main variables predictive of severe depressive psychopathology. Old age, good problem-solving skills, and ability to pursue personal goals were identified as protective factors.

CONCLUSIONS

The COVID-19 pandemic underlined the need for support amongst emotionally vulnerable women with pre-existing mental health conditions, partly reflecting the cumulative effects of traumas.
