Advancing our understanding of loneliness and mental health problems in young people

Loneliness in the Digital World: protocol for a co-produced ecological momentary assessment study in adolescents

INTRODUCTION

Loneliness has been identified as an important public health issue, peaking during adolescence. Previous research has suggested that social interaction is a key factor in loneliness, and positive social interaction can act as a protective factor against loneliness. However, it is unclear whether there are differing impacts of in-person and online social interaction on adolescents' loneliness and mental health. Ecological Momentary Assessment (EMA) designs are ideally suited for better understanding these associations.

METHOD AND ANALYSIS

In the 'Loneliness in the Digital World' study, we will use a co-developed EMA design to capture daily social interactions, loneliness and mental health such as positive and negative emotions, depression and anxiety in approximately 200 adolescents aged 12-15 years. We will combine this with comprehensive information gathered from online surveys. Analysing the data using techniques such as dynamic structural equation modelling, we will examine, among other research questions, the associations between online and in-person social interaction and feelings of loneliness. The results can help inform interventions to support adolescents with high levels of loneliness and poor mental health.

ETHICS AND DISSEMINATION

We received the ethics approval for the data collection from The Academic and Clinical Central Office for Research and Development, followed by the College of Medicine and Veterinary Medicine Ethics panel at University of Edinburgh, and finally reviewed by East of Scotland Research Ethics Service. The results will be disseminated through journal publications, conferences and seminar presentations and to relevant stakeholders such as teachers.

Young people's views on the acceptability and feasibility of loneliness interventions for their age group

BACKGROUND

Loneliness is a frequently reported problem for young people aged 16 to 24 years old. A variety of interventions have been developed (but in most cases not extensively evaluated) to try and tackle loneliness in this age group. These include interpersonal, intrapersonal, and social approaches that vary in their content and mechanisms of action. The current study aimed to qualitatively examine young peoples' views on the acceptability and feasibility of different loneliness interventions.

METHODS

Young people from 16 to 24 years old living in the United Kingdom who self-identified as having experienced loneliness were recruited to participate in this study. We conducted semi-structured qualitative interviews to assess their views on the acceptability and feasibility of loneliness interventions for their age group. Interviews were analysed using inductive reflexive thematic analysis.

RESULTS

Our analysis of 23 individual interview transcripts identified six themes. These related to the appropriate stage for intervention and how different types of strategies may be best suited to particular contexts; the key facilitators and barriers to engaging young people in an intervention; considerations for optimising the delivery of an intervention; divergent views on technology use in strategies to manage loneliness; the scope of an intervention and whether it takes a targeted or general approach; and the idea of combining different options within an intervention to allow tailoring to individual preferences and nature of loneliness.

CONCLUSIONS

These findings demonstrate the need for continued development of individualised interventions designed to help manage loneliness in this age group. Future loneliness strategies should be co-produced with young people to ensure that they suit the varying needs of this population.

Understanding Loneliness in Younger People: Review of the Opportunities and Challenges for Loneliness Interventions

Loneliness affects the quality of life of people all around the world. Loneliness is also shown to be directly associated with mental health issues and is often the cause of mental health problems. It is also shown to increase the risk of heart diseases and other physical illnesses. Loneliness is studied both from the social and medical sciences perspectives. There are also interventions on the basis of health informatics, information and communication technologies (ICTs), social media, and other technological solutions. In the literature, loneliness is studied from various angles and perspectives ranging from biological to socioeconomical and through anthropological understandings of technology. From the ICT and technological sides, there are multiple reviews studying the effectiveness of intervention strategies and solutions. However, there is a lack of a comprehensive review on loneliness that engulfs the psychological, social, and technological studies of loneliness. From the perspective of loneliness informatics (ie, the application of health informatics practices and tools), it is important to understand the psychological and biological basis of loneliness. When it comes to technological interventions to fight off loneliness, the majority of interventions focus on older people. While loneliness is highest among older people, theoretical and demographical studies of loneliness give a U-shaped distribution age-wise to loneliness; that is, younger people and older people are the demographics most affected by loneliness. But the strategies and interventions designed for older people cannot be directly applied to younger people. We present the dynamics of loneliness in younger people and also provide an overview of the technological interventions for loneliness in younger people. This paper presents an approach wherein the studies carried out from the perspectives of digital health and informatics are discussed in detail. A comprehensive overview of the understanding of loneliness and the study of the overall field of tools and strategies of loneliness informatics was carried out. The need to study loneliness in younger people is addressed and particular digital solutions and interventions developed for younger people are presented. This paper can be used to overcome the challenges of technological gaps in the studies and strategies developed for loneliness. The findings of this study show that the majority of interventions and reviews are focused on older people, with ICT-based and social media-based interventions showing promise for countering the effects of loneliness. There are new technologies, such as conversational agents and robots, which are tailored to the particular needs of younger people. This literature review suggests that the digital solutions developed to overcome loneliness can benefit people, and younger people in particular, more if they are made interactive in order to retain users.

The lived experience of adolescent depression: A systematic review and meta-aggregation

BACKGROUND

The under-detection of depression in adolescents suggests that a better understanding of its presentation may be needed. Conceptualizations of adolescent depression are largely the same as adult depression, with minimal consideration of developmental stage. Exploration of first-hand accounts could help to identify any unique features of adolescent depression. Therefore, this systematic review aimed to understand the lived experience of adolescents with depression to inform clinical practice.

METHODS

The review was registered with PROSPERO (CRD42020198141). Databases (PsychINFO, CINAL, MEDLINE and EMBASE) were searched in March 2022 to identify peer-reviewed qualitative studies on first-hand experiences of adolescent depression. The Joanna Briggs Institute's qualitative data extraction tool and checklist for qualitative research were used to obtain study data and assess methodological quality of included papers. Meta-aggregation was the method of synthesis, whereby extracted themes from the papers were grouped according to shared meanings.

RESULTS

Fifteen papers of mixed methodological quality were identified for inclusion from screening a total of 1,983 references. Studies were published between 2002 and 2021, spanned seven countries and included participants aged 11 to 22 years old. Aggregation of 56 themes resulted in 16 categories and 3 synthesized findings encompassing key aspects of adolescent depression: causes, symptoms and coping. Variability in adolescents' perspectives across these domains was evident. Some symptoms described, such as social disconnection and anger, are not listed in existing diagnostic criteria.

CONCLUSIONS

Subjective experiences of depression among adolescents vary and may not entirely match diagnostic criteria. Awareness of this when assessing for depression may improve detection and help to ensure adolescents feel understood.

Loneliness in young people: a multilevel exploration of social ecological influences and geographic variation

BACKGROUND

Loneliness is a growing public health concern, yet little is known about loneliness in young people. The current study aimed to identify social ecological factors related to loneliness and examine the extent to which geographic region may account for differences in loneliness.

METHODS

The data come from a cross-sectional sample of 6503 young people living in the UK. Loneliness was measured using the UCLA 3-item scale. Bivariate analyses were used to test associations between each predictor and loneliness. Multilevel models were used to identify key social ecological factors related to loneliness, and the extent to which loneliness may vary across geographic regions (local authority districts).

RESULTS

Sociodemographic, social, health and well-being, and community factors were found to be associated with loneliness. Geographic region was associated with 5-8% of the variation in loneliness. The effect of gender, sexual orientation and minority ethnic background on loneliness differed across regions.

CONCLUSIONS

This is the first study to highlight modifiable social and community factors related to youth loneliness, and individual vulnerabilities, such as poor mental well-being. Results related to geographic differences suggest that local-level initiatives may be most appropriate in tackling loneliness, rather than wider, less contextualized national efforts.

Experience of loneliness on well-being among young individuals: A systematic scoping review

A systematic scoping review was conducted to explore the current evidence on the experience of loneliness influencing well-being among youths. The electronic databases Scopus, APA PsycINFO, Emerald Insight and One Search were used to identify relevant studies, followed by an analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. Reference lists of all shortlisted articles were searched for additional studies. 20 studies (quantitative, qualitative and mixed) published in the English language were identified for inclusion. Findings illustrate that the experience of loneliness is a complex, evolutionary process influenced by relational and environmental factors. Results from the studies identified factors that promote lower experience of loneliness and better well-being in future life stages. Future research can substantiate the issues related to young individuals being socially isolated from others for a prolonged duration.

Exploring the experiences of loneliness in adults with mental health problems: A participatory qualitative interview study

BACKGROUND

Loneliness is associated with many mental health conditions, as both a potential causal and an exacerbating factor. Richer evidence about how people with mental health problems experience loneliness, and about what makes it more or less severe, is needed to underpin research on strategies to help address loneliness.

METHODS

Our aim was to explore experiences of loneliness, as well as what helps address it, among a diverse sample of adults living with mental health problems in the UK. We recruited purposively via online networks and community organisations, with most interviews conducted during the COVID-19 pandemic. Qualitative semi-structured interviews were conducted with 59 consenting participants face-to-face, by video call or telephone. Researchers with relevant lived experience were involved at all stages, including design, data collection, analysis and writing up of results.

FINDINGS

Analysis led to identification of four overarching themes: 1. What the word "lonely" meant to participants, 2. Connections between loneliness and mental health, 3. Contributory factors to continuing loneliness, 4. Ways of reducing loneliness. Central aspects of loneliness were lack of meaningful connections with others and lack of a sense of belonging to valued groups and communities. Some drivers of loneliness, such as losses and transitions, were universal, but specific links were also made between living with mental health problems and being lonely. These included direct effects of mental health symptoms, the need to withdraw to cope with mental health problems, and impacts of stigma and poverty.

CONCLUSIONS

The multiplicity of contributors to loneliness that we identified, and of potential strategies for reducing it, suggest that a variety of approaches are relevant to reducing loneliness among people with mental health problems, including peer support and supported self-help, psychological and social interventions, and strategies to facilitate change at community and societal levels. The views and experiences of adults living with mental health problems are a rich source for understanding why loneliness is frequent in this context and what may address it. Co-produced approaches to developing and testing approaches to loneliness interventions can draw on this experiential knowledge.

Contribution of perceived loneliness to suicidal thoughts among French university students during the COVID-19 pandemic

Restrictive measures during the COVID-19 epidemic have led to increased levels of loneliness, especially among university students, although the influence on suicidal thoughts remains unclear. In this cross-sectional study of 1913 French university students, those with the highest level of loneliness had a fourfold increased risk of suicidal thoughts. Perceived loneliness should be incorporated into suicide risk assessment, and assistance in coping with loneliness should be considered as a means of reducing suicidal risk in vulnerable groups, like university students.

The Relationship Between Loneliness and Depressive Symptoms in Children and Adolescents: A Meta-Analysis

Objective: To provide a quantitative assessment of the literature examining the cross-sectional association between loneliness and depressive symptoms in children and adolescents. Method: A total of 44 studies from 35 articles (n = 27, 214; mean age 13.63 years; 51% female) met inclusion criteria. Results: A medium, positive correlation between loneliness and depressive symptoms in children and adolescents was found (r = .48). Age and gender did not moderate the relationship between loneliness and depressive symptoms. Conclusion: Loneliness may be a particular risk factor for depression. These results have implications for COVID-19 disease containment measures.

Perceived Peer Relationships in Adolescence and Loneliness in Emerging Adulthood and Workplace Contexts

Background

A common life-course hypothesis is that negative early-life experiences contribute to poor health in later-life. However, little is known about perceived peer relationships during adolescence and the feeling of loneliness in emerging adulthood. This study explores the perception of adolescent peer relationships in a school context and its association with loneliness in adulthood and in workplace contexts.

Methods

This study used data from a cohort sample of 2,520 adolescents from the Taiwan Youth Project (N = 2,520), consisting of eleven waves of data collected from 2000 to 2017. Major measures included the Loneliness Scale (6-item de Jong Gierveld short scale) and perceived peer relationships (classroom cohesion and perceived popularity among classmates) in middle school. Multivariate multinomial logistic regressions were used to estimate the associations of perceived peer relationships during adolescence and workplace characteristics with loneliness in adulthood.

Results

Positive perceived peer relationships in adolescence were significantly related to decreased risk of serious social loneliness [Relative risk ratios (RRR) 0.70, 95% CI: 0.58–0.85] and severe social/emotional loneliness (RRR = 0.76, 95% CI: 0.63–0.91) in adulthood. Workplace satisfaction was a protective factor of severe social/emotional loneliness in employed adults.

Conclusion

Adolescents who perceived peer relationships in middle school as positive were less likely to report social and emotional loneliness during adulthood. Satisfaction in the workplace characteristics was also associated with lower risk of loneliness in adulthood. Theoretical and policy implications are discussed.

Eating Disorders and Intimate Partner Violence: The Influence of Fear of Loneliness and Social Withdrawal

Eating disorders are vulnerability factors that increase the likelihood of intimate partner violence. However, the mechanisms underlying this relationship are unclear. Although eating disorders have been associated with increased perception and fear of loneliness, they have also been associated with increased social withdrawal resulting from decreased enjoyment of social situations and poorer social functioning. The purpose of the present study was to examine the mediating role of fear of loneliness in the relationship between the behavioural characteristics of eating disorders and intimate partner violence, as well as to explore the moderating role of social withdrawal in the relationship between fear of loneliness and intimate partner violence. The sample comprised 683 participants (78% female and 22% male) with a mean age of 21.14 years (SD = 2.72). The psychometric scales used were Eating Disorders Inventory (EDI 2), Emotional Dependency Questionnaire (EDQ), Coping Strategies Inventory (CSI) and the Violence Received, Exercised and Perceived in Youth and Adolescent Dating Relationships Scale (VREPS). The hypothesised model was tested by path analysis using maximum likelihood. The path analysis of the hypothesised model showed that inefficacy, fear of maturity, and impulsivity were the behavioural characteristics of eating disorders predominantly related to fear of loneliness. Fear of loneliness had no direct significant effect on any of the received violence variables. However, interaction effects indicated that there was a moderately significant effect of fear of loneliness on physical, psychological, and social violence received as a function of levels of social withdrawal. These findings show the need to take into account and work on fear of loneliness and social withdrawal among individuals with an eating disorder to decrease the likelihood of establishing violent intimate partner relationships. Improving interpersonal functioning and social support is key to recovery from eating disorders.

Neurological and Psychological Characteristics of Young Nitrous Oxide Abusers and Its Underlying Causes During the COVID-19 Lockdown

Background

The COVID-19 pandemic has a serious impact on the mental health of the public due to its economic and social impact. And psychological effects have led to drug and alcohol abuse. After the city lifted the lockdown, we consecutively encountered several young nitrous oxide abusers admitted to hospital for neurological treatment.

Purpose

To inform physician decisions and social intervention, this observational study aimed at investigating the neurological and psychological characteristics of nitrous oxide abusers and its underlying causes during the COVID-19 lockdown.

Methods

The nitrous oxide abusers who sought neurological treatment at our hospital between May 2020 and June 2020 were enrolled. Clinical data including socio-demographic, physical examination, laboratory examination, electromyography and neuroimaging were collected. Their motivations for inhaling nitrous oxide, knowledge about the nitrous oxide abuse and the accompanying of family were investigated face to face. Psychological status was assessed by the Symptom Checklist 90 (SCL-90) psychological evaluation.

Results

Six nitrous oxide abusers were enrolled and the age was 22 ± 4.3. Clinical presentations included varying degrees of limb numbness and an ataxic gait. Laboratory examination revealed that all the patients did not have pernicious anemia, 4 patients had decreased vitamin B12 while 3 patients exhibited elevated homocysteine levels. MR of the spinal cord revealed that 4 patients had abnormal signals in the cervical spinal cord of high symmetry with splayed or inverted V sign after T2WI. Electromyogram (EMG) test showed 5 patients had peripheral nerve damage. The SCL-90 psychological evaluation results indicated that all patients had severe anxiety, depression and psychosis and they had severer psychological problems than ordinary citizens. Their motives for inhaling nitrous oxide are to relieve boredom, curiosity and buddy pressure. Their family spent <1 day per week to stay with them during city lockdown.

Conclusion

The enrolled patients caused by abuse of nitrous oxide presented with symptoms of subacute combined with spinal degeneration. They had more serious psychological problems related to the COVID-19 pandemic. These cases make us value the psychological problems of young people under the outbreak and take multi-layered measures from families, schools (companies), hospitals, and governments to address it.

Loneliness and mental health in children and adolescents with pre-existing mental health problems: A rapid systematic review

OBJECTIVES

Periods of social isolation are associated with loneliness in children and young people, and loneliness is associated with poor mental and physical health. Children and young people with pre-existing mental health difficulties may be prone to loneliness. Containment of COVID-19 has necessitated widespread social isolation, with unprecedented school closures and restrictions imposed on social interactions. This rapid review aimed to establish what is known about the relationship between loneliness and mental health problems in children and young people with pre-existing mental health problems.

METHODS

We sought to identify all primary research that examined the cross-sectional and longitudinal associations between loneliness/perceived social isolation and mental health in children and young people with pre-existing mental health problems. We also aimed to identify effective interventions that reduce the adverse impact of loneliness. A rapid systematic search was conducted using MEDLINE, PsycINFO, and Web of Science.

RESULTS

Of 4,531 papers screened, 15 included children and young people with pre-existing mental health conditions. These 15 studies included 1,536 children and young people aged between 6 and 23 years with social phobia, anxiety and/or depression, and neurodevelopmental disorders. Loneliness was associated with anxiety and depression both cross-sectionally and prospectively in children and young people with mental health problems and neurodevelopmental conditions. We found preliminary evidence that psychological treatments can help to reduce feelings of loneliness in this population.

CONCLUSIONS

Loneliness is associated with depression and anxiety in children and young people with pre-existing mental health conditions, and this relationship may be bidirectional. Existing interventions to address loneliness and/or mental health difficulties in other contexts may be applied to this population, although they may need adaptation and testing in younger children and adolescents.

PRACTITIONER POINTS

Loneliness is common in children and young people, and during periods of enforced social isolation such as during COVID-19, children and young people report high levels of loneliness (or increased rates of loneliness). The review showed that loneliness is associated, both cross-sectionally and prospectively, in children and young people with mental health problems and also in children and young people with neurodevelopmental conditions, such as autism spectrum disorder. Thus, loneliness is a possible risk factor of which mental health providers should be aware. Maintaining social contact both by direct and by indirect means, especially through the Internet, could be important in mitigating loneliness. Interventions to address loneliness should be further developed and tested to help children and young people with pre-existing mental health problems who are lonely by preventing exacerbation of their mental health difficulties, in particular anxiety and depression.

Loneliness and mental well-being in the Polish population during the COVID-19 pandemic: a cross-sectional study

OBJECTIVE

There is a growing concern that the restrictions imposed due to the COVID-19 pandemic could lead to increased loneliness and mental disorders, which are considered a major public health problem. The aim of the study was to assess loneliness, anxiety, depression and irritability in the Polish population during the COVID-19 pandemic.

DESIGN

A cross-sectional study. The study participants completed an online questionnaire using the computer-assisted web interview technique. Data were collected using Revised UCLA Loneliness Scale and Hospital Anxiety and Depression Scale.

SETTING

Poland.

PARTICIPANTS

This study was conducted between 6 October and 12 October 2020, in a representative sample of 890 Polish residents.

PRIMARY OUTCOME MEASURES

Self-reported loneliness; sociodemographic and COVID-19 pandemic factors associated with loneliness, anxiety, depression and irritability.

RESULTS

The analyses showed a moderately high degree of loneliness in 22%, symptoms of anxiety in 27%, depression in 14% and irritability in 33% of the respondents. The increasing severity of anxiety, depression and irritation in the study group was accompanied by higher loneliness. Generally, younger people, both tested positive for SARS-CoV-2 and those who experienced home quarantine, scored higher in both scales.

CONCLUSIONS

It is necessary to identify those most vulnerable to loneliness, anxiety and depression during a crisis to assess health needs and proactively allocate resources during and after the pandemic. Loneliness, anxiety, depression and irritability are important factors to consider in a population of younger, disadvantaged people, who tested positive for SARS-CoV-2, people who were quarantined at home, and people who believe that their physical and mental health is worse than in the pre-pandemic period. It is important to cater for the mental health of individuals during the COVID-19 pandemic and to promote psychological interventions to improve mental well-being in potentially vulnerable social groups.

Processes and structures in intergenerational programs: a comparison across different types of programs

OBJECTIVES

Given the widely acknowledged benefits of intergenerational programs (IGPs), we compared processes and structures across different IGP types and explored potential areas for improvement.

DESIGN

Thirteen IGPs were classified into three types: arts, learning, and assistance programs. Data were collected through direct structured interviews and analyzed quantitatively and qualitatively.

SETTING

Participants were recruited from community-based IGPs in the greater Tel Aviv area of Israel.

PARTICIPANTS

Eighty-four older participants (OPs), 97 younger participants (YPs), and 21 organizers were interviewed.

MEASUREMENTS

Questions included participant demographics as well as closed- and open-ended questions regarding processes based on the Impact of Intergenerational Programs Questionnaire (IIPQ).

ANALYSIS

Responses to closed-ended questions were compared among IGP types and age groups using two-way ANOVAs for ordinal data, and chi-squares for nominal data. Responses to open-ended questions by OP, YP, and program organizers about potential areas for improvement were analyzed using thematic analysis.

RESULTS

Processes in need of improvement were preparation and guidance, length of program participation, and monitoring of activities, which differed across IGP types and age groups. These processes were related to broader structural problems such as lack of resources, organizers' poor employment conditions, and inadequate public services for older persons in Israel.

CONCLUSIONS

Our study highlights the complex relationships between IGP types, processes, and structures. IGP processes and goals can be hindered by structural variables such as insufficient funding, infrastructure, and public services for older adults.

Linking childhood emotional neglect to adolescents' parent-related loneliness: Self-other differentiation and emotional detachment from parents as mediators

BACKGROUND

The detrimental role of childhood emotional neglect (CEN) on long-term affective and social development has received increasing attention in the literature. Individuals who were emotionally neglected during their childhood are more prone to feeling isolated and excluded by their parent during adolescence. However, little is known about the mediating processes underlying this association.

OBJECTIVE

This study investigated whether self-other differentiation (SOD) and emotional detachment from parents mediate the link between CEN and parent-related loneliness.

METHOD AND PARTICIPANTS

A sample of 535 high school students aged 13-18 years (63.6% female; M_age = 16.21; SD = 1.40) completed questionnaires regarding demographics, CEN, SOD, emotional detachment, and parent-related loneliness.

RESULTS

After controlling for demographic covariates, structural equation modeling (SEM) showed that (a) CEN was positively associated with parent-related loneliness (β = 0.64, p < .001), (b) SOD did not mediate the relationship between CEN and parent-related loneliness (β = -0.01, p = .142), (c) emotional detachment partially mediated the relationship between CEN and parent-related loneliness (β = 0.16, p < .001), and (d) SOD and emotional detachment partially and sequentially mediated the link between CEN and parent-related loneliness, albeit with a small effect size (β = 0.02, p = .027).

CONCLUSIONS

The findings underscore the significance of the link between CEN and parent-related loneliness in adolescence. Moreover, our results suggest that some adolescents with a history of CEN have difficulties in establishing clear boundaries between "self" and "other" and tend to engage in emotionally detached relationships with their parents, which may lead them to feel more parent-related loneliness. Clinical implications and directions for future research are discussed.

Interventions to address loneliness and social isolation in young people: A systematic review of the evidence on acceptability and effectiveness

INTRODUCTION

Loneliness is prevalent and associated with negative health outcomes in young people. Our understanding of how it can be best addressed is limited. This systematic review aims to assess the acceptability and effectiveness of interventions to reduce and prevent loneliness and social isolation in young people.

METHODS

Six bibliographic databases were searched; references of included studies were screened for relevant literature. A pre-defined framework was used for data extraction. Quality appraisal was performed using the Mixed Method Appraisal Tool. Data were synthesised narratively.

RESULTS

9,358 unique references were identified; 28 publications from 16 interventions met the inclusion criteria. The majority of interventions were high intensity, individual or small group interventions, often targeted at specific 'at risk' populations. While 14 interventions were associated with a statistically significant reduction in loneliness or social isolation, the heterogeneous measures of loneliness, small sample sizes, short periods of follow-up and high attrition rates limit evidence on effectiveness. Interventions implemented in more general populations of young people appeared more acceptable than those in specific 'at risk' populations.

CONCLUSION

High intensity interventions are unlikely to be feasible at a population level. Further work is required to develop and evaluate theoretically-informed loneliness interventions for young people that reach wider audiences.

The Patterns and Predictors of Loneliness for the Chinese Medical Students Since Post-Lockdown to New Normal With COVID-19

Background: The coronavirus disease 2019 (COVID-19)-related quarantine has had unique psychological challenges for medical students, particularly loneliness. In this study, we demonstrated the patterns and predictors of loneliness in medical students since post-lockdown to new normal with COVID-19.

Methods: A convenience sampling method was used in this study. Face-to-face online questionnaires of UCLA Loneliness Scale and psychological characteristics scales were completed by 1,478 participants. Latent profile analysis and multinominal logistic regressions were performed.

Results: Three latent profile models were identified in this study: low loneliness (52.3%), interpersonal sensitivity loneliness (3.5%), and high loneliness (44.1%). Sophomore (Est = 1.937; p < 0.05) and junior students (Est = 2.939; p < 0.05), neuroticism (Est = 2.475; p < 0.05), high arousal symptoms (Est = 2.618; p < 0.01), and the quality of support from friends (Est = 2.264; p < 0.05) were the risk factors for high loneliness profile. In addition, sophomore (Est = 2.065; p < 0.05) and junior students (Est = 2.702; p < 0.01), openness (Est = 2.303; p < 0.05), and conscientiousness personality (Est = −2.348; p < 0.05) were the predictors of an interpersonal sensitive loneliness profile. Good peer relationship (Est = −2.266; p < 0.05) and other support (Est = −2.247; p < 0.05) were protective factors for low loneliness profile.

Limitations: Participants were selected from one medical university; the generalizability is limited.

Conclusions: Timely loneliness-focused interventions should be targeted on the different profiles and predictors of loneliness in medical students.

Perceived Health Problems of Young Single-Person Households in Housing Poverty Living in Seoul, South Korea: A Qualitative Study

There is an increased prevalence of housing poverty among urban young adults; however, research on housing poverty and health is lacking. This study examined the effects of housing poverty on the health concepts of young people living alone. In-depth interviews were conducted with 20 single-person households, with individuals aged 19–39 years, living in Seoul, the demographic group with the highest housing poverty rate in South Korea. Data were analyzed using the constant comparison method. Based on the health concepts of the respondents, housing poverty negatively affected health in terms of “the occurrence and continuation of anxiety,” “the increase and continuation of lethargy,” “the difficulty in managing daily life and taking care of health,” “the lack of a dependable support person,” and “the difficulty in preventing and treating disease.” The majority of young people experienced difficulties responding to their situations, and their housing poverty was hard to overcome. This study suggests the need to expand healthy housing policies, strengthen housing safety nets, and enhance access to public resources needed for a healthy living.

A prefrontal-paraventricular thalamus circuit requires juvenile social experience to regulate adult sociability in mice

Juvenile social isolation reduces sociability in adulthood, but the neural circuit mechanisms are poorly understood. We found that, in male mice, 2 weeks of social isolation immediately following weaning leads to a failure to activate medial prefrontal cortex (mPFC) neurons projecting to the posterior paraventricular thalamus (pPVT) during social exposure in adulthood. Chemogenetic or optogenetic suppression of mPFC->pPVT activity in adulthood was sufficient to induce sociability deficits without affecting anxiety-related behaviors or preference toward rewarding food. Juvenile isolation led to both reduced excitability of mPFC->pPVT neurons and increased inhibitory input drive from low-threshold spiking somatostatin interneurons in adulthood, suggesting a circuit mechanism underlying sociability deficits. Chemogenetic or optogenetic stimulation of mPFC->pPVT neurons in adulthood could rescue the sociability deficits caused by juvenile isolation. Our study identifies a pair of specific mPFC excitatory and inhibitory neuron populations required for sociability that are profoundly affected by juvenile social experience.

The experience of loneliness among young people with depression: a qualitative meta-synthesis of the literature

BACKGROUND

Young people have a higher prevalence of loneliness than other age groups, and they are also at risk of depression. Quantitative studies describe a bidirectional association between loneliness and depression, but there is limited understanding of how these influence each other. Little is known about the experience of loneliness among young people with depression. Qualitative approaches may help understand the relationship between loneliness and depression among young people, and how to intervene to improve outcomes. We aimed to conduct a meta-synthesis to understand the complex inter-relationship between loneliness and depression among young depressed people by synthesising evidence from a systematic review of qualitative studies.

METHODS

We conducted a meta-synthesis of qualitative studies capturing experiences of loneliness among young people with depression. We systematically searched six electronic databases for selected search terms, critically appraised eligible studies, and analysed the data from included studies using the approach of thematic synthesis. We used feedback from an inter-disciplinary research workshop to improve reflexivity.

RESULTS

Our inclusion criteria identified fourteen studies. Our analysis identified four themes: (1) social withdrawal due to poor mental health, (2) non-disclosure of depression contributing to social distance, (3) the desire to connect, and (4) paradoxes of loneliness and depression. These themes illustrated a range of pathways between depression and loneliness, and a sense of how these might be mutually reinforcing. Our findings suggest that where depressed individuals engage in certain behaviours (withdrawing; not confiding) for a range of reasons, this can lead to feelings of loneliness, an awareness of which worsens their mood, thus perpetuating their depression.

CONCLUSIONS

Young people with depression experience loneliness as an insurmountable distance between themselves and others. Our findings identified non-disclosure of depression, and the debilitating nature of the depressive symptomatology, as factors perpetuating a vicious cycle of loneliness and depression. They suggest that approaches to tackling the problem might include helping young people communicate about their depression to trusted friends and educating their social networks in how to support them. The wider research literature suggests that cognitive interventions may have a role in shifting maladaptive cognitions about their social world.

Adverse adolescence experiences, feeling lonely across life stages and loneliness in adulthood

Loneliness is a mental health issue emerging over the life course. This study examines the latent structure of adult loneliness in a non-Western society and its association with adverse adolescence experiences (AAEs) as well as feeling lonely during middle school, high school, and college. Method: A cohort sample living in Northern Taiwan (N = 2,289) was analyzed from adolescence to adulthood. The de Jong Gierveld Loneliness Scale operationalized loneliness by a three-cluster model to present the latent structure of loneliness: emotional, serious emotional, and severe emotional/social loners. AAEs (e.g., abuse, neglect, and dysfunctional family) were measured by seven items. Multivariate multinomial logistic regression models were used to explore the longitudinal effects of AAEs and feeling lonely reported during middle school, high school, and college on adult loneliness. Results: AAEs and feeling lonely during adolescence were significantly associated with serious emotional loneliness and severe emotional/social loneliness during adulthood, even after adjusting for the individual’s characteristics. Attendance at a 4-year college was associated with decreased odds of serious emotional loneliness and severe emotional/social loneliness. Conclusions: Adults with AAEs and feelings of loneliness over life stages are more likely to report loneliness in the emotional and social domains.

The association of loneliness after sudden bereavement with risk of suicide attempt: a nationwide survey of bereaved adults

PURPOSE

We aimed to test the hypothesis that among people who experience sudden bereavement, loneliness is associated with post-bereavement suicide attempt and post-bereavement suicidal ideation, even when adjusting for network size.

METHODS

We analysed cross-sectional data collected in the 2010 UCL Bereavement Study, to identify 3193 respondents who had experienced sudden bereavement. We used multivariable logistic regression to test for an association between loneliness (using a newly-developed eight-item loneliness measure) and post-bereavement suicide attempt and suicidal ideation, adjusting for socio-demographic factors, pre-bereavement depression and self-harm, and network size.

RESULTS

Among bereaved adults, loneliness was significantly associated with probability of post-bereavement suicide attempt (AOR 1.19; 95% CI 1.14-1.25) and of post-bereavement suicidal ideation (AOR 1.24; 95% CI 1.20-1.28), with estimates unchanged by adding perceived stigma of the bereavement to adjusted models. There was no association between suicide bereavement and loneliness (adjusted coefficient 0.22; 95% CI - 0.12 to 0.45; p = 0.063). The association of loneliness and suicide attempt risk was similar whether participants were bereaved by suicide or not.

CONCLUSIONS

People who report feeling lonely after sudden bereavement are more likely to make a suicide attempt after their loss, even when taking into account their network size and the perceived stigma of the sudden bereavement. There is no evidence that the effects of loneliness on suicidality are specific to suicide bereavement. This work identifies loneliness as a potential target for suicide prevention interventions among bereaved people. It also fuels interest in longitudinal research investigating loneliness as a putative mediator of suicide risk.

Project Synergy: co-designing technology-enabled solutions for Australian mental health services reform

Project Synergy aims to test the potential of new and emerging technologies to enhance the quality of mental health care provided by traditional face-to-face services. Specifically, it seeks to ensure that consumers get the right care, first time (delivery of effective mental health care early in the course of illness). Using co-design with affected individuals, Project Synergy has built, implemented and evaluated an online platform to assist the assessment, feedback, management and monitoring of people with mental disorders. It also promotes the maintenance of wellbeing by collating health and social information from consumers, their supportive others and health professionals. This information is reported back openly to consumers and their service providers to promote genuine collaborative care. The online platform does not provide stand-alone medical or health advice, risk assessment, clinical diagnosis or treatment; instead, it supports users to decide what may be suitable care options. Using an iterative cycle of research and development, the first four studies of Project Synergy (2014-2016) involved the development of different types of online prototypes for young people (i) attending university; (ii) in three disadvantaged communities in New South Wales; (iii) at risk of suicide; and (iv) attending five headspace centres. These contributed valuable information concerning the co-design, build, user testing and evaluation of prototypes, as well as staff experiences during development and service quality improvements following implementation. Through ongoing research and development (2017-2020), these prototypes underpin one online platform that aims to support better multidimensional mental health outcomes for consumers; more efficient, effective and appropriate use of health professional knowledge and clinical skills; and quality improvements in mental health service delivery.

Loneliness in young adulthood: Its intersecting forms and its association with psychological well-being and family characteristics in Northern Taiwan

Objectives

Most researchers have examined forms of loneliness as discrete and emotional distress. The approach proposed in this study captures the reality that many persons experience more than one dimension of loneliness—varying degrees coupled with their psychological well-being in a family context. This study explores the latent structure of loneliness during young adulthood and its association with psychological well-being, as well as how these are related to their family characteristics in adolescence.

Methods

Data are from 2,748 young people, a cohort sample from the Taiwan Youth Project (TYP). Loneliness was assessed by a 6-item de Jong-Gierveld short scale with emotional and social loneliness domains. We describe the clustering between loneliness domains and psychological well-being, namely depressive symptoms, self-esteem, suicidal thoughts, and alcohol use using latent class cluster analysis. In addition to incorporating the Taiwanese family context, multivariate multinomial logistic regression models included data on family cohesion and parental guan (parental control) in adolescence. This might be associated with choices in partnership and childbearing, and influence loneliness in young adulthood.

Results

Our results demonstrate a three-cluster model of loneliness involving emotional loners, serious emotional loners, and severe emotional/social loners. We also found that a feeling of serious emotional loneliness and severe emotional/social loneliness were significantly associated with psychological well-being, even adjusting for individual characteristics. Among young adults who had a partner, the married adults were significantly less likely to feel serious emotional loneliness than those who were living alone. Furthermore, young adults with stronger family cohesion during early adolescence were less likely to suffer from serious emotional loneliness (Relative risk ratios [RRR] 0.77, 95% CI 0.65–0.91) and severe emotional/social loneliness (RRR 0.54, 95% CI 0.34–0.85) in young adulthood.

Discussion

This measurement strategy provides a foundation for future research into how experts can address loneliness clusters in order to better understand psychological well-being during young adulthood and family context in adolescence. This is important because our results suggest that the various loneliness domains do not occur independently, but rather are embedded in patterns and are associated with family characteristics.
