RESUMEN
BACKGROUND: Cross-sectional studies show associations between loneliness, social isolation and physical inactivity. Cohort studies are shedding light on these relationships and further longitudinal investigations are needed. PURPOSE: This study aimed to assess the longitudinal and bidirectional associations between loneliness, social isolation, and physical inactivity. METHODS: Data were drawn from five annual waves of the Household and Labour Dynamics of Australia Survey (2015-2019), providing a sample of 17,303 persons (mean age = 46.3 years [SD = 18.0], 49.4% female). Relationships between loneliness, social isolation, and physical inactivity were examined using cross-lagged panel modeling, with estimation of simultaneous cross-lagged effects across each wave. Models adjusted for sociodemographic factors, chronic disease status, psychological distress, and mutually for social isolation or loneliness. Moderation of associations by sex was explored. RESULTS: There were modest lagged effects of physical inactivity on loneliness across the survey waves (odds ratio 1.16 [95% confidence interval 1.04-1.29] to 1.20 [1.07, 1.33]). A lagged effect of physical inactivity upon social isolation was only present across three of the waves (odds ratio 1.20 [1.02-1.41] to 1.23 [1.05-1.42]). While loneliness and social isolation showed lagged effects upon physical inactivity, these did not persist with adjustment for psychological distress. CONCLUSIONS: Longitudinal analysis found that physical inactivity consistently predicted loneliness, but not social isolation. After adjustment for confounding, loneliness and social isolation were not predictive of physical inactivity. While the strength of the associations was modest, further investigation is warranted of the type and dose of physical activity that is most beneficial for reducing loneliness.
Loneliness and social isolation have been found to be risk factors for heart disease, depression, and early death. A possible way that loneliness and isolation contribute to poor health is through their effect on lifestyle behaviors. In this study, we aimed to explore the relationship between loneliness and isolation and physical inactivity. Most studies that have examined this in the past have used data from one point in time, so it has been unclear whether loneliness or isolation leads to physical inactivity (or vice versa). We used data collected over 5 years from 17,303 adults in the Household, Income and Labour Dynamics of Australia survey. After adjusting for various contributing factors in our analysis, we did not find that loneliness or social isolation in 1 year was consistently associated with physical inactivity in the following year. On the contrary, we found that being physically inactive was associated with loneliness in the following year. Physical inactivity was related to social isolation across some years, but this was less consistent. Overall, it appears that promoting physical activity will be beneficial for reducing loneliness.

PURPOSE: Loneliness and social isolation are risk factors for poor health, but few effective interventions are deployable at scale. This study was conducted to determine whether acts of kindness can reduce loneliness and social isolation, improve mental health, and neighbourhood social cohesion. METHOD: Three randomized controlled trials (RCTs) were conducted in the USA, UK, and Australia, involving a total of 4284 individuals aged 18-90 years old, randomized to the KIND challenge intervention or a waitlist control group. Participants allocated to the intervention were asked to do at least one act of kindness per week within a four-week period. The primary outcome was loneliness and secondary outcomes included measures of social isolation, mental health, and neighbourhood social cohesion. RESULTS: There was a significant, albeit small, intervention effect after four weeks for reduced loneliness in the USA and the UK, but not for Australia. Relative to controls, KIND challenge participants also showed significantly reduced social isolation and social anxiety in the USA, and reduced stress in Australia. There was also reduced neighbourhood conflict in the USA, increased number of neighbourhood contacts in the USA and Australia, greater neighbourhood stability and feelings of neighbourhood importance in the UK, and better neighbourhood social relationships in Australia. CONCLUSION: Promoting the provision of social support through small acts of kindness to neighbours has the potential to reduce loneliness, social isolation and social anxiety, and promote neighbourhood relationships, suggesting a potential strategy for public health campaigns.

BACKGROUND: Loneliness and social isolation are increasingly recognised as global public health threats, meaning that reliable and valid measures are needed to monitor these conditions at a population level. We aimed to determine if robust and practical scales could be derived for conditions such as loneliness and social isolation using items from a national survey. METHODS: We conducted psychometric analyses of ten items in two waves of the Household, Income and Labour Dynamics in Australia Survey, which included over 15,000 participants. We used the Hull method, exploratory structural equation modelling, and multidimensional item response theory analysis in a calibration sample to determine the number of factors and items within each factor. We cross-validated the factor structure using confirmatory factor analysis in a validation sample. We assessed construct validity by comparing the resulting sub-scales with measures for psychological distress and mental well-being. RESULTS: Calibration and cross-validation consistently revealed a three-factor model, with sub-scales reflecting constructs of loneliness and social isolation. Sub-scales showed high reliability and measurement invariance across waves, gender, and age. Construct validity was supported by significant correlations between the sub-scales and measures of psychological distress and mental health. Individuals who met threshold criteria for loneliness and social isolation had consistently greater odds of being psychologically distressed and having poor mental health than those who did not. CONCLUSIONS: These derived scales provide robust and practical measures of loneliness and social isolation for population-based research.

BACKGROUND: Loneliness and social isolation are recognised as social problems and denote a significant health burden. The aim of this study was to conduct a systematic literature review to explore the health state utility values (HSUVs) associated with loneliness and/or social isolation. METHOD: Peer-reviewed journals published in English language that reported both HSUVs along with loneliness and/or social isolation scores were identified through five databases. No restrictions were made relating to the population, study design or utility estimation method used. RESULTS: In total, 19 papers were included; 12 included a measure of loneliness, four studies included a measure of social isolation and three studies considered both loneliness and social isolation. All studies focused on individuals with pre-existing health conditions-where the EQ-5D-3L instrument was most frequently used to assess HSUVs. HSUVs ranged from 0.5 to 0.95 in those who reported not being lonely, 0.42 to 0.97 in those who experienced some level of loneliness, 0.3 to 0.87 in those who were socially isolated and 0.63 to 0.94 in those who were not socially isolated. CONCLUSION: There was significant variation in HSUVs complicated by the presence of co-morbidities, population heterogeneity, variations in methods used to derive utility scores and differences in the measurement of loneliness and/or social isolation. Nevertheless, the lower HSUVs observed should be considered to significantly impact quality of life, though we also note the need for further research to explore the unique impact of loneliness and social isolation on HSUVs that can be used in the future economic evaluations.

BACKGROUND: Loneliness impedes recovery from mental illness. Despite increased interest in loneliness in psychosis, qualitative methods are underused in clinical research on this topic. AIMS: We used qualitative interviews to explore loneliness among persons with schizophrenia spectrum disorders (SSDs). We examined which aspects of living with psychosis were associated with the experience of loneliness, including symptomatology, social relationships, and disruptions in school/work. METHODS: Sixteen participants diagnosed with SSDs engaged in semi-structured, qualitative interviews about loneliness. Participants commented on current activities and social relationships, including their perceptions of the quantity, quality and types of relationships. Important demographic and clinical information was acquired through communication with participants and/or through medical record review. Thematic analysis was used to examine interview content. RESULTS: Our analyses revealed four key topic areas and several sub-themes related to loneliness across participants, including aspects of the physical environment (e.g. financial limitations), social context (e.g. lacking a romantic partner), and psychological functioning (e.g. psychotic/symptoms) that impact lonely feelings. Participants commented on coping strategies to manage loneliness and provided suggestions for possible interventions. CONCLUSIONS: Persons diagnosed with SSDs report significant and impactful feelings of loneliness. This study highlights the need for novel and effective treatments targeting loneliness in this population.

BACKGROUND: Community interventions are often promoted as a way of reducing loneliness and social isolation in our neighbourhoods. However, those community interventions are rarely examined within rigorous study designs. One strategy that holds the potential to reduce loneliness and can promote health and wellbeing is doing acts of kindness. The current study involves evaluating the impact of kindness acts on loneliness in community-dwelling individuals using an online social networking platform. METHODS: This study is made up of three randomised controlled trials conducted in three countries. Each randomised controlled trial has two arms (intervention vs waitlist control) and is designed to compare the effectiveness of the KIND challenge, which involves doing at least one act of kindness per week within a four-week period. This study will recruit users of an online community, be randomised online, and will be conducted using online assessments. We will first explore the effects of the intervention on the primary outcome of loneliness, followed by secondary outcomes, social isolation, neighbour relationship quality and contact, mental health symptoms, stress, quality of life, and positive affect. Further, we will assess the feasibility, acceptability, and safety of the KIND Challenge. DISCUSSION: This study, designed to evaluate the impact of kindness on the community, will be the first large scale randomised control trial conducted across three countries, Australia, UK, and USA. It will examine the potential of community-led interventions to reduce loneliness, improve social isolation, and promote neighbourhood cohesion, health, and wellbeing, which is especially crucial during the COVID-19 public health crisis.

PURPOSE: Loneliness is increasingly recognised as the next critical public health issue. A plausible reason for this concern may be related to emerging societal trends affecting the way we relate, communicate, and function in our social environment. In 2006, a prominent review of the clinical significance of loneliness was published. However, there has not been a comprehensive update on known and emerging risk factors and correlates of loneliness since then. Furthermore, there is no conceptual model that has been developed to better account for the complexity of loneliness and to inform the development of evidence-based solutions as we challenge the issues of the twenty-first century. METHODS: We reviewed the current literature to identify either known or emerging risk factors and correlates of loneliness since 2006. This includes new or known evidence on: (1) demography; (2) health, including physical health; mental health; cognitive health; brain, biology, and genetics; and (3) socio-environmental factors including digital communication and the workplace. RESULTS: We synthesized the literature according to a new proposed conceptual model of loneliness which showed the interplay between known and emerging correlates and risk factors from demography, health, to socio-environmental factors. In the conceptual model of loneliness, we illustrated how solutions can be delivered and tailored to an individual based on their life circumstances and preferences. CONCLUSION: We concluded by making specific recommendations in advancing our scientific understanding of loneliness. Our knowledge can only be deepened if we increase scientific rigour via accounting for confounding variables and using longitudinal, multi-disciplinary, and multiple methodologies in research. We also call for the rigorous evaluation of programs targeting loneliness.

The article, "The economic costs of loneliness: a review of cost_of_illness and economic evaluation studies", written by Cathrine Mihalopoulos was originally published electronically on the publisher's internet portal (currently SpringerLink) on 22 May 2019 with open access.'
RESUMEN
PURPOSE: Loneliness and social isolation can occur at all stages of the life course and are recognized as a global health priority. The aim of this study was to review existing literature on the economic costs associated with loneliness and social isolation as well as evidence on the cost-effectiveness of interventions to prevent or address loneliness and social isolation. METHODS: A bibliographic database search was undertaken in Medline, PsycINFO, CINAHL, and Embase, supplemented by a grey literature search and a reference list search. Papers were included that were published in English language in peer-reviewed literature in the past 10 years, reporting costs of loneliness and/or social isolation or economic evaluations of interventions whose primary purpose is to reduce loneliness and/or social isolation, including return on investment (ROI) or social return on investment (SROI) studies. RESULTS: In total, 12 papers were included in this review, consisting of four cost-of-illness studies, seven economic evaluations and five ROI or SROI studies. Most studies were conducted in the UK and focused on older adults. Due to the inconsistent use of the terms loneliness and social isolation, as well as their measurement, the true economic burden can only be estimated to a certain extent and the comparability across economic evaluations and ROI studies is limited. CONCLUSIONS: The paucity of evidence that is available primarily evaluating the economic costs of loneliness indicates that more research is needed to assess the economic burden and identify cost-effective interventions to prevent or address loneliness and social isolation.

PURPOSE: Loneliness has been identified as a significant challenge for people with psychosis. Interventions targeting loneliness are lacking but adopting a positive psychology approach may reduce loneliness, promote well-being, and support meaningful social interactions. Together with youth mental health consumers, we developed a digital smartphone application (app) called +Connect, which delivers positive psychology content daily for 6 weeks. MATERIALS AND METHODS: Twelve participants diagnosed with a psychotic disorder were recruited from early psychosis services. Loneliness was assessed pre-intervention, post-intervention, and 3-month post-intervention. Acceptability, feasibility, and usability were measured post-intervention, including a semi-structured interview on the user's experience of +Connect. RESULTS: We found evidence for the feasibility of +Connect. All but two participants completed the +Connect program, completing 95% (40.10 out of 42 days) of the program. Furthermore, 66.67% (8 out of the 12 participants) remained engaged with the program 3-months post-intervention. Our data indicates preliminary evidence that +Connect may reduce loneliness, with scores from pre-intervention (M = 50.00, SD = 8.47) to post-intervention (M = 48.10, SD = 10.38) and 3-months post-intervention (M = 42.89, SD = 7.04). We found that positive reinforcement of in-game rewards and evidence of positive mood changes added to the feasibility of the app. Regarding acceptability, while 10% (1/10 participants) reported not finding +Connect useful or enjoyable, 90% of participants agreed that +Connect helped them to increase their social confidence, enjoy life, look forward to being with other people, and feel more connected with others. Participant interviews supported these results, with participants highlighting the app's strengths in providing useful information, stimulating self-reflection, fostering positive affect, and encouraging transfer of skills into their social interactions. DISCUSSION: While preliminary findings indicated that +Connect yielded high levels of acceptability and feasibility, it is important to consider that we recruited a small and selected sample of lonely young people. Further iterations of this proof of concept app, which can incorporate participant feedback such preferences for increased personalisation, in-app feedback, and gamification, may allow an opportunity to test an improved version in the future.

OBJECTIVE: Eating disorders (EDs) and social anxiety disorder (SAD) are highly co-occurring. This comorbidity is extremely relevant, given that individuals with comorbid ED-SAD are less likely to seek and/or benefit from ED treatment. METHOD: We used network analysis to conceptualize ED-SAD comorbidity in a sample of 2,215 participants with a primary diagnosis of ED, SAD, or no known diagnosis. We used novel network analyses methods to select symptoms for our models, identify potential illness pathways (i.e., bridge symptoms) between disorders and underlying vulnerabilities (e.g., perfectionism, social appearance anxiety), and to compare across sample types (e.g., clinical vs. nonclinical). We also tested several novel network analyses methods aimed at the following methodological concerns: (a) topological concerns (i.e., which items should be included in NA models), (b) how to use empirical indices to quantify bridge symptoms and (c) what differences in networks across samples mean. RESULTS: We found that difficulty with drinking beverages and eating in public were bridge symptoms between ED and SAD. We also found that feeling nervous about one's appearance was a bridge symptom. CONCLUSIONS: We identified public eating and drinking as bridge symptoms between EDs and SAD. Future research is needed to test if interventions focused on public eating and drinking might decrease symptoms of both EDs and SAD. Researchers can use this study (code provided) as an exemplar for how to use network analysis, as well as to use network analysis to conceptualize ED comorbidity and compare network structure and density across samples.

PURPOSE: The aim of the review is to understand the relationships between loneliness and related psychological and social factors in individuals with psychosis. Loneliness is poorly understood in people with psychosis. Given the myriad of social challenges facing individuals with psychosis, these findings can inform psychosocial interventions that specifically target loneliness in this vulnerable group. METHODS: We adhered to the PRISMA guidelines and systematically reviewed empirical studies that measured loneliness either as a main outcome or as an associated variable in individuals with psychosis. RESULTS: A total of ten studies examining loneliness in people diagnosed with a psychotic disorder were examined. Heterogeneity in the assessment of loneliness was found, and there were contradictory findings on the relationship between loneliness and psychotic symptomatology. In individuals with psychosis, loneliness may be influenced by psychological and social factors such as increased depression, psychosis, and anxiety, poor social support, poor quality of life, more severe internalised stigma and perceived discrimination, and low self-esteem. CONCLUSIONS: The relationship between loneliness and psychosis remains poorly understood due to a lack of rigorous studies. Although having strong social relationships is crucial to facilitate recovery from serious mental illness, psychosocial interventions that specifically target loneliness in individuals with psychosis are lacking and sorely needed. Interventions targeting loneliness in those with psychosis will also need to account for additional barriers associated with psychosis (e.g., social skill deficits, impoverished social networks, and negative symptoms).

High social anxiety in adults is associated with self-report of impaired friendship quality, but not necessarily with impairment reported by friends. Further, prospective prediction of social anxiety and friendship quality over time has not been tested among adults. We therefore examined friendship quality and social anxiety prospectively in 126 young adults (67 primary participants and 59 friends, aged 17-22 years); the primary participants were screened to be extreme groups to increase power and relevance to clinical samples (i.e., they were recruited based on having very high or very low social interaction anxiety). The prospective relationships between friendship quality and social anxiety were then tested using an Actor-Partner Interdependence Model. Friendship quality prospectively predicted social anxiety over time within each individual in the friendship, such that higher friendship quality at Time 1 predicted lower social anxiety approximately 6 months later at Time 2. Social anxiety did not predict friendship quality. Although the results support the view that social anxiety and friendship quality have an important causal relationship, the results run counter to the assumption that high social anxiety causes poor friendship quality. Interventions to increase friendship quality merit further consideration.

PURPOSE: In a previous study, individuals who followed a particular new religious movement (NRM) reported significantly less distress even though they reported similar levels of delusional ideation when compared with individuals diagnosed with psychotic disorders. Protective factors such as social relationship quality and quality of life (QOL) were hypothesized to explain attenuated distress associated with delusional ideation. METHODS: NRM individuals (n = 29), individuals diagnosed with psychotic disorders (n = 25), and control individuals (n = 63) were recruited. Psychotic symptoms, delusion-proneness, and facets of social relationships quality and QOL were examined across group. Potential moderators of the relationship between group membership and distress were further examined in multiple regression models. RESULTS: NRM participants reported more social relationships that were of higher quality (as demonstrated by more crisis supports, unique and overlap supports, more helpful supports and more reciprocated supports) than individuals with psychotic disorders. NRM participants also reported significantly higher QOL than individuals with psychotic disorders. Furthermore, NRM participants reported more distinct and less reciprocated supports, and significantly higher psychological, environmental, and total QOL, when compared with control participants. The relationship between group membership, delusional ideation, and distress was moderated by relationship reciprocity as well as by total QOL. CONCLUSIONS: Findings highlight the importance of establishing healthy reciprocal social relationships and improving QOL in people diagnosed with psychotic disorders, as these factors may act as a buffer against distress associated with delusional beliefs.

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 (ß = - 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 (ß = - 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.

Objectives: In current study, we aim to extend previous research by investigating the unique impact of loneliness on health literacy and health-related factors of young adults, after controlling for social isolation, depressive symptomology, and social anxiety, as well as evaluate how social isolation and loneliness differ in their impact on health literacy, and health-related factors among young adults, after accounting for abovementioned concomitant variables. Methods: Using a cross-sectional study design, 521 young adults completed an online survey in 2020, where they self-reported their loneliness, social isolation, health-related factors, and health literacy data. Results: Increased loneliness was associated with decrease in several health literacy domains (e.g., poorer social support for health, lower appraisal of health information, among others) and increase in some health-related factors (e.g., higher perceived stress, higher negative affect), among young adults, even after controlling for social anxiety, depressive symptomology, and social isolation. Contrastingly, increase in social isolation was associated with changes in some health-related factors - more somatic health complaints, higher alcohol use, poorer cognitive and physical functioning, and lower scores for only one health literacy domain (i.e., social support for health) among young adults, after adjusting for the influence of social anxiety, depressive symptomology, and loneliness. Conclusion: Even after accounting for the influence of several co-occurring social and mental health symptoms, higher loneliness was associated poorer health literacy and health-related factors in young adults. We also found loneliness and social isolation may differ in the mechanisms through which they impact health literacy and health-related factors in young adults.
RESUMEN
OBJECTIVES: We aimed to investigate the mechanisms underlying loneliness, social anxiety, depression and emotion dysregulation, as well as how these relationships differ based on social isolation risk. DESIGN: We employed an online survey study to measure variables cross-sectionally. METHODS: A total of 1239 (77.2% Female, Mage = 21.52, SD = 2.32) participants completed measures of loneliness, social isolation risk, social anxiety, depression and emotion dysregulation. A moderated serial mediation model was conducted to determine whether emotion dysregulation and depression jointly mediate the relationship between loneliness and social anxiety and to determine whether these relationships are moderated by risk of social isolation. RESULTS: Loneliness was found to predict social anxiety and was mediated by emotion dysregulation and depression both independently and combined. Participants with a low risk of social isolation were found to be protected against poor mental health. CONCLUSIONS: Our studies replicate previous findings showing a relationship between loneliness and social anxiety. We also extend current knowledge to show the importance of social contact for protecting against elevated levels of social anxiety and depression. Overall, we provide empirical evidence for the role of social connection in managing mental health symptoms.
