The developmental course of loneliness in adolescence: Implications for mental health, educational attainment, and psychosocial functioning

Detecting loneliness among late adolescents: Validation and testing of a detection tool based on the UCLA Loneliness Scale

The high prevalence of loneliness among adolescents, combined with their tendency to conceal it, highlights the need for strategies that identify and support those youth who experience loneliness. This study aimed to validate and test a detection tool for late adolescents within educational settings in Denmark. The tool, which was based on nine items from the UCLA Loneliness Scale (UCLA-9), underwent a three-stage refinement and testing process. In Stage 1, psychometric analyses and cognitive interviews investigated the reliability, validity, and usability of the tool among adolescents ages 16-20 years; potential cut-off scores for identification of cases on the three-dimensional scale were explored. Stage 2 involved a feasibility test in three educational institutions. Field observations and qualitative interviews with participants offered insights and recommendations for implementation of the tool in educational settings. Stage 3 involved 1728 students engaged in the Danish Lift program run in three municipalities. Among those youth, the refined UCLA-9 demonstrated robust psychometric properties, identifying 9% of adolescents as cases with a cut-off score of ≥10 on each subscale. The UCLA-9 showed promise in identifying adolescents experiencing loneliness, which often co-occurred with poor mental health. Challenges remain in determining appropriate cut-off scores for the identification of cases.

Loneliness trajectories and psychological distress in youth: Longitudinal evidence from a population-based sample

This pre-registered secondary analysis aimed to examine distinct longitudinal loneliness trajectories in youth and whether these trajectories were associated with psychological distress at final follow-up in the UK Household Longitudinal Study. Participants (N = 827, 55.1% female, Time 1: M ± SD = 16.50 ± 0.50 years) provided data during Waves 9, 10 and 11. K-means longitudinal clustering analysis was used to identify clusters of participants with distinct loneliness trajectories across measurement waves. We identified four clusters demonstrating distinct trajectories of loneliness: stable low (40.7%), stable high (20.6%), moderate decreasing (19.6%) and low increasing (19.1%). Compared to 'stable low loneliness', 'stable high' and 'low increasing' loneliness clusters were significantly associated with psychological distress at Wave 11 following adjustment for sex, ethnicity, parent's highest educational achievement and Wave 9 psychological distress. The current study offers an important contribution to the literature on patterns of youth loneliness and mental health consequences.

A framework for understanding adverse adolescent experiences

Adolescence (ages 10-24) is characterized by cognitive, behavioural and social development. Childhood environments are typically centred on home and care settings, whereas adolescents increasingly engage with peer and community environments. These changing environments confer risks of experiencing specific adversities at different ages. Despite the unique characteristics of adversities in adolescence and potential associations with lifespan outcomes, few frameworks exist to systematize adversities in adolescents. Here we review current research and propose an approach specific to this developmental period: the adverse adolescent experiences (AAEs) framework. Building on existing models (for example, the adverse childhood experiences framework), the AAEs focus on potentially traumatizing experiences during adolescence. The framework builds on Bronfenbrenner's ecological systems theory to conceptualize adversities at intrapersonal, interpersonal, community and societal levels. We argue that this approach can enhance our understanding of adolescent adversity, facilitate the study of its potential effects, and guide prevention and intervention efforts.

Parental smoking is associated with adolescent loneliness: evidence from 71 low- and middle-income countries

Introduction

The association between parental smoking and adolescent mental health is not well understood. We aimed to examine the association between parental smoking and adolescent loneliness using global data collected from the Global School-based Student Health Survey (GSHS) between 2009 and 2019.

Methods

A total of 187,552 adolescents aged 12-15 years in 71 low- and middle-income countries (LMIC) from the GSHS with cross-sectional design were included in this study. Loneliness was defined as feeling lonely sometimes or more frequently in the past 12 months. Parental smoking, reported by the adolescent, was defined as the use of any form of tobacco by the father and/or mother. Logistic regression models were used to examine the odds ratio (OR) of adolescent loneliness according to parental smoking status.

Results

Compared with neither parent smoking, parental smoking was associated with adolescent loneliness (father only: OR = 1.18, 95% CI = 1.10-1.26; mother only: OR = 1.39, 95% CI = 1.15-1.67; both: OR = 1.65, 95% CI = 1.41-1.93) after adjustment for potential covariates. Subgroup analyses stratified by sex, age, and WHO region showed similar results (except not in the African and Western Pacific regions).

Discussion

Parental smoking is associated with loneliness in adolescents from LMIC. Our finding expands the well-known physical damage of parental smoking in adolescents to the psychological damage. Strict policies and strategies should be established to encourage smoking cessation for parents who are current smokers.

Social exclusion as a major outcome domain of psychotic disorders: early predictors, and associations with non-recovery and clinical staging 21 years after a first episode of psychosis

PURPOSE

People with psychotic disorders have high levels of social exclusion; however, little is known about its early predictors. We present a long-term observational cohort study aimed at examining early risk factors for later social exclusion.

METHODS

A total of 243 subjects were assessed at their first psychotic episode for early risk factors including sociodemographic variables, familial risk of major mental disorders, perinatal complications, childhood factors, and adolescent factors and re-assessed after a mean follow-up of 21 years for 12 social exclusion domains: leisure activities, housing, work, income, neighborhood deprivation, educational attainment, physical and mental health, family and social support, legal competence, and discrimination. The ability of risk factors to predict social exclusion was examined using hierarchical linear regression.

RESULTS

Overall social exclusion was independently predicted by low parental socio-economic status, length of follow-up, familial risk of schizophrenia, obstetric complications, neurodevelopmental delay, poor childhood adjustment, childhood adversity, poor adolescent social networks, poor adolescent adjustment, and low premorbid IQ. The model explained 58.2% of the variance in total social exclusion score. Each social exclusion domain was predicted by a different set of variables, which explained between 17.8 and 57.0% of their variance, although low socio-economic status, familial risk of schizophrenia, obstetric complications, childhood adversity, and poor social networks predicted most of the social exclusion domains.

CONCLUSION

Early risk factors strongly predicted later social exclusion. A multifaceted approach to preventing later social exclusion is crucial in people with a first episode of psychosis and early risk factors of social exclusion.

The changing impacts of social determinants on youth mental health in Australia

AIMS

Most lifetime mental health disorders begin by age 25 years, and the prevalence among young people has been increasing over recent years. We sought to understand what impact, if any, social determinants have had on this increase through the analysis of an Australian longitudinal dataset (with data from 2007 to 2021).

METHODS

The analysis focused on five social determinants: loneliness and lack of social support, family relationships, participation in education and employment, receipt of government benefits and relative socio-economic status. We analysed cross-sectional changes in self-reported psychological distress between 2007 and 2021 (using the Kessler-10 item; K10 scores) and examined the effects of these five social determinants on psychological distress using weighted linear regression models.

RESULTS

We identified a significant increase in psychological distress among Australians from 2007 to 2021, with the sharpest rise among those aged 15 to 25 years, who saw more than doubling in the percentage of high and very high K10. This period also saw an increase in the prevalence of social determinants such as loneliness and lack of social support, as well as poor family relationships, particularly in 2021 post COVID-19 pandemic. Regression models suggest loneliness and lack of social support had the most pronounced and increasing impact on psychological distress, followed by poor family relationships.

DISCUSSION

The observed significant and steady increases in psychological distress and related social determinant factors, particularly loneliness and lack of social support among young people, highlight the urgent need for comprehensive actions. Coordinated research and community-based initiatives are needed to deliver intrapersonal, interpersonal and socially-focused interventions with a holistic approach to support psychosocial wellbeing. Policymakers must adopt a comprehensive shift in political commitment and a whole-of-government approach to address these challenges.

Meaning mindset theory: a transdiagnostic approach to mental health promotion and intervention for children

A transdiagnostic approach is increasingly recognized as crucial in the prevention or treatment of child internalizing and externalizing mental health concerns. There is substantial overlap and comorbidity among various mental health concerns and the onset of one mental illness elevates the risk of others, underscoring the potential limitations of singular-focused mental health education or treatment. Meaning Mindset Theory (MMT) is a transdiagnostic framework developed and evaluated over the past decade in Canada as a promising new approach. MMT emphasizes agency over thoughts and behaviors, empathy and social competence skills, and meaningful engagement to enhance resilience for both internalizing and externalizing symptoms. The DREAM Program-Developing Resilience through Emotions, Attitudes, and Meaning is a mental health education program grounded in MMT principles. This program has enhanced meaning mindset-agency over thoughts and behaviors, hope for a future that is good, positive self-concept, and openness to learning, new experiences, and feelings-as well as both internalizing and externalizing mental health. To date, the DREAM program, as well as MMT more broadly, has been tested in diverse populations with school-aged children, families, neurodiverse and intellectually gifted young people, homeless men, and Black families, among others. Future research should explore the efficacy of an MMT in therapeutic settings compared to standard treatments, potentially enhancing mental health intervention strategies for Canadian children and families.

The Risks of Being a Wallflower: Exploring Links Between Introversion, Aspects of Solitude, and Indices of Well-Being in Adolescence

The aim of the current study was to examine the unique relations between introversion and indices of well-being while accounting for aspects of solitude (i.e., time spent alone, shyness, affinity for solitude, and negative thinking while alone). Participants were n = 1036 adolescents (15-19 years of age, M = 16.19 years, SD = 0.58; 67% girls) who completed a series of self-report measures assessing introversion, time spent alone, negative thinking while alone, motivations for solitude (shyness, affinity for solitude), and indices of well-being (i.e., loneliness, positive/negative affect, general well-being). Overall, results from correlational analyses indicated that introversion was associated with poorer functioning across all indices of well-being. However, when controlling for aspects of solitude, results from hierarchical regression analyses indicated a complex set of associations that varied across indices of well-being. Introversion remained associated significantly and negatively with well-being and positive affect, was no longer related significantly to loneliness, and became related significantly and negatively to negative affect. Findings are discussed in terms of how personality characteristics and aspects of solitude can impact the well-being of adolescents.

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.

Risky behaviors in Ethiopian university students and its relationship with loneliness and coping self-efficacy

Research shows that risky behavior peaks in young adulthood, endangering young adult's mental health and making it difficult for them to grow up to be responsible members of society. As a result, this study aimed to adapt the Risk Behavior Scale into Amharic and examine the relationships between risky behaviors, loneliness, and coping self-efficacy. A cross-sectional research design was used and convenience sampling was employed to gather data from a total of 242 Ethiopian university students. Confirmatory Factor Analysis (CFA) was carried out to test the factor structures of the Risky Behaviors Scale. The CFA results validated the scale's four-factor structures (χ2 = 435, df = 183, (p < .001), CFI = 0.94, TLI = 0.91, RMSEA = 0.08, and SRMR =0.05). This would make it possible for mental health experts to research the psychological impacts of risky behaviors (alcohol use, suicidality, drug use, and khat use) in Ethiopian young adults. The findings of hierarchical regression analysis revealed that male gender and loneliness were predictors of risky behavior. This research holds significant implications for interventions that attempt to reduce loneliness in young adults to alter their vulnerabilities to risky behaviors.

Loneliness and teacher-student relationships in children and adolescents: Multilevel cross-cultural meta-analyses of cross-sectional and longitudinal studies

This study synthesized the literature from international and Chinese databases regarding the associations between loneliness and the quality of affective teacher-student relationships (TSRs) among children and adolescents ages 5.34-17.09 years. Forty-seven studies published between 2005 and 2023 were included in a cross-sectional meta-analysis using a multi-level approach. Moderators of the relationship, including culture, study, sample, and measurement characteristics, were also examined. Findings indicated a significant medium effect size (r = -0.226) between loneliness and TSRs with effects moderated by students' gender and national cultural background (i.e., Hofstede's Power Distance and Long-term/Short-term Orientation Dimensions). Longitudinal meta-analyses were performed with six studies by using cross-lagged regression to investigate the prospective effects between these two variables. Results showed that loneliness predicted subsequent TSRs (β = -0.1661) and TSRs predicted subsequent loneliness (β = -0.0917), indicating a reciprocal prospective relationship over time. The findings emphasize not only the role of teachers in students' experiences of loneliness, but also the role that loneliness has on an individual's relationships with others. Recommendations for intervention include (a) increasing teacher awareness of student loneliness and (b) ensuring that any school-based work considers the specific social-cultural perspective.

"It's Time to see What I Can Do": A Mixed-Methods Investigation into Trajectories of Resilience in Adolescents during the COVID-19 Pandemic

There is a concern that adolescent mental well-being and resilience has been adversely affected by the COVID-19 pandemic. Consequently, the aim of the current investigation was to track adolescents' resilience from the initial months of the pandemic (T1) to approximately two years later (T2) using both qualitative and quantitative methods. Through interviews, thirty-one adolescents narrated their COVID-19 experiences and reflected on their mental well-being across this timespan. Using these accounts, we identified four groups of adolescents exhibiting one of the following trajectories of resilience: (1) Enduring resilience, (2) Reaching resilience, (3) Declining resilience and (4) Enduring non-resilience. Our findings revealed that most adolescents were able to maintain or develop good resilience on prolonged exposure to COVID-19 adversity (trajectories 1 and 2). This finding is contrary to the prevailing notion that the majority of adolescents' mental well-being and hence resilience was adversely impacted by COVID-19 in the short and long term. Further qualitative analysis identified key factors that contributed to maintaining and developing greater levels of resilience during the pandemic: quality of friendships, quality of family relationships and regaining a sense of control. Lastly, we found a lack of congruence between quantitative and qualitative measures of mental well-being and resilience, suggesting that they might tap into different constructs/experiences. Significantly, our findings highlight that the majority of teens showed adaptive resilience during the pandemic and highlight the need for further longitudinal qualitative and quantitative research to assess both adaptive and maladaptive impacts of adversity on the adolescents' mental well-being and resilience.

Predictors of loneliness among middle childhood and adolescence during the COVID-19 pandemic

Social contexts (e.g., family, friends) are important in predicting and preventing loneliness in middle childhood (MC) and adolescence; however, these social contexts were disrupted during the COVID-19 pandemic. Comparison of social context factors that may differentially contribute to loneliness at each developmental stage (MC vs. adolescence) during the COVID-19 pandemic have been overlooked. This study examined longitudinal predictors of loneliness, including social contexts and COVID-19 impact, within MC (8-12y) and adolescence (13-17y). Parents reported on demographic information, and their children completed surveys on COVID-19 impact, loneliness, and family functioning using the COVID-19 Exposure and Family Impact Survey (CEFIS), the NIH Toolbox Loneliness (Ages 8-17) measure, and the PROMIS Family Relationships Short Form 4a measure, respectively. Regression models examined time one (T1; May-June 2020) predictors of time two (T2; November 2020-January 2021) MC child (n=92, Mage=10.03) and adolescent (n=56, Mage=14.66) loneliness. For the MC child model, significant predictors of higher loneliness included worse family functioning as well as higher COVID-19 impact and lower family income. On the other hand, higher adolescent loneliness was significantly predicted by not having married/partnered parents and was marginally significantly predicted by higher COVID-19 impact. The regression model with the full sample and interaction terms revealed no significant interactions, but that lower family functioning and higher COVID-19 impact were significant predictors of higher loneliness. Lower family income and lower in-person communication were marginally significant predictors of higher loneliness in the combined interaction model. Lastly, further exploratory mediation analyses displayed that family functioning significantly mediated the relationship between COVID-19 impact and T2 loneliness only for MC children and the full sample. Results support future interventions focused on optimizing family functioning to help mitigate MC loneliness in the context of adversity, such as a global pandemic.

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.

COVID-19 Pandemic Quarantines and Mental Health Among Adolescents in Norway

Importance

Adolescence is a critical developmental phase when mental health disorders, such as anxiety and depression, often emerge. Stringent public health measures and quarantine mandates during the COVID-19 pandemic could threaten adolescent mental health.

Objective

To investigate the associations of public health measures and quarantine experiences with mental distress among Norwegian adolescents and to explore if certain vulnerability factors moderate these associations.

Design, Setting, and Participants

This longitudinal cohort study used repeated measures to capture variations in mental distress explained by the stringency of public health measures and quarantine experiences. Data from the Norwegian Mother, Father, and Child cohort study were linked to national health registries and a national stringency index from April 1, 2020, to February 17, 2021. Participant included 7787 Norwegian adolescents aged 16 to 18 years. Data were analyzed from October 2022 to October 2023.

Exposures

Stringency index of public health measures and quarantine experiences including recent quarantine (within the last 2 weeks) and quarantine frequency (cumulative number of quarantine episodes).

Main Outcome and Measures

Mental distress was measured using the Hopkins Symptom Checklist across 6 data collection waves.

Results

In this study, 7787 participants were included in the analysis (4473 female [57%]; mean [SD] age, 17.0 [0.6] years). Stringent public health measures (β = 0.18; SE, 0.02; P < .001), recent quarantine (β = 0.11; SE, 0.02; P < .001), and frequent quarantine (β = 0.08; SE, 0.01; P < .001) were associated with higher levels of mental distress. The associations between public health measures and mental distress were not moderated by sex, age, prepandemic anxiety or depression, or genetic liability for mental health conditions. Frequency of quarantine appeared to be more strongly associated with mental distress among younger adolescents (β = -0.04; SE, 0.01; P = .008), those with parents with lower education (β = -0.04; SE, 0.01; P = .007), and those with lower genetic risk for depression (β = -0.03; SE, 0.01; P = .006).

Conclusions and Relevance

In this study, younger adolescents, those with parents with lower education, or those with low genetic liability for depression appeared more vulnerable when being quarantined several times. These findings emphasize the need for targeted support strategies to better protect adolescent well-being during future crises. Adolescents who experienced increased mental distress during the COVID-19 pandemic may be at risk of continued mental health problems and in need of ongoing support.

On the Edge of Psychopathology: Strong Relations Between Reversed Self-compassion and Symptoms of Anxiety and Depression in Young People

Self-compassion is assumed to have a protective role in the etiology of emotional problems in adolescents. This assumption is primarily based on correlational data revealing negative correlations between the total score on the Self-Compassion Scale (SCS) and symptom measures of anxiety and depression. Recently, however, the SCS has been criticized because this scale not only consists of items measuring compassionate self-responding (i.e., self-kindness, common humanity, and mindfulness), but also includes 'reversed' items measuring uncompassionate self-responding (i.e., self-criticism, isolation, and overidentification), which would undermine the validity of the scale as an index of a protective construct. The present article used two methods to demonstrate that compassionate (positive) and uncompassionate (negative) self-responding have differential effects on emotional problems in youths. In the first part, a meta-analysis based on 16 relevant studies demonstrated a modest protective effect of positive self-compassion on anxiety/depression and a large (and significantly stronger) vulnerability effect of negative self-compassion on such emotional symptoms. In the second part, network analyses were conducted on three previously collected data sets and these analyses again showed that negative self-compassion is more closely connected to young people's symptoms of anxiety and depression than positive self-compassion. It is argued that the observed differential effects should not be discarded as a subversive fallacy, but rather offer an opportunity for studying the role of self-compassion in adolescents' emotional psychopathology in a more sophisticated way, taking into account both protection and vulnerability.

Trajectories of Loneliness During Adolescence Predict Subsequent Symptoms of Depression and Positive Wellbeing

There is a need to identify the outcomes of changes in loneliness during adolescence, and to consider this within a multidimensional framework of loneliness. This study considered the effects of different trajectories of change in Isolation Loneliness and in Friendship Loneliness upon both positive wellbeing and symptoms of depression. To achieve this, 1782 (43% female; 12.92 years old at the start of the study, SD = 1.60) young people took part in a longitudinal study with four data points across 2 years. Four Isolation Loneliness trajectories and five Friendship Loneliness trajectories were identified. Youth who experienced low levels of Isolation Loneliness that subsequently increased appear to be at particular risk for poor outcomes. Similarly, initially high levels of Friendship Loneliness that decreased rapidly, or which began at a low level and only increased marginally, seem to also be a risk. Loneliness is a multi-dimensional construct and its development during adolescence impacts upon young people's depressive symptomatology and positive mental wellbeing.

Social isolation from childhood to mid-adulthood: is there an association with older brain age?

BACKGROUND

Older brain age - as estimated from structural MRI data - is known to be associated with detrimental mental and physical health outcomes in older adults. Social isolation, which has similar detrimental effects on health, may be associated with accelerated brain aging though little is known about how different trajectories of social isolation across the life course moderate this association. We examined the associations between social isolation trajectories from age 5 to age 38 and brain age assessed at age 45.

METHODS

We previously created a typology of social isolation based on onset during the life course and persistence into adulthood, using group-based trajectory analysis of longitudinal data from a New Zealand birth cohort. The typology comprises four groups: 'never-isolated', 'adult-only', 'child-only', and persistent 'child-adult' isolation. A brain age gap estimate (brainAGE) - the difference between predicted age from structural MRI date and chronological age - was derived at age 45. We undertook analyses of brainAGE with trajectory group as the predictor, adjusting for sex, family socio-economic status, and a range of familial and child-behavioral factors.

RESULTS

Older brain age in mid-adulthood was associated with trajectories of social isolation after adjustment for family and child confounders, particularly for the 'adult-only' group compared to the 'never-isolated' group.

CONCLUSIONS

Although our findings are associational, they indicate that preventing social isolation, particularly in mid-adulthood, may help to avert accelerated brain aging associated with negative health outcomes later in life.

Adolescent loneliness across the world and its relation to school climate, national culture and academic performance

BACKGROUND

Loneliness during adolescence has adverse consequences for mental health, education and employment outcomes. Yet, we know little about common correlates of loneliness among adolescents, making intervention work difficult.

AIMS

In this study, we (1) explore individual-, school- and country-level correlates of loneliness to help identify potential intervention targets, and (2) examine the influence of loneliness on academic performance.

SAMPLE

A total of 518,210 students aged 15 years from 75 countries provided self-reported loneliness data.

RESULTS

Using multilevel modelling, we found individual-, school- and country-level correlates of self-reported school-based loneliness, and showed that loneliness negatively influenced academic performance.

CONCLUSIONS

Based on the findings, interventions that focus on enhancing social and emotional skills, increasing trust between teachers and students and changing school climate to be more inclusive are likely to be the most effective for adolescents; they should also be culturally sensitive.

A cross-lagged twin study of emotional symptoms, social isolation and peer victimisation from early adolescence to emerging adulthood

BACKGROUND

Emotional symptoms, such as anxiety and depressive symptoms, are common during adolescence, often persist over time, and can precede the emergence of severe anxiety and depressive disorders. Studies suggest that a vicious cycle of reciprocal influences between emotional symptoms and interpersonal difficulties may explain why some adolescents suffer from persisting emotional symptoms. However, the role of different types of interpersonal difficulties, such as social isolation and peer victimisation, in these reciprocal associations is still unclear. In addition, the lack of longitudinal twin studies conducted on emotional symptoms during adolescence means that the genetic and environmental contributions to these relationships during adolescence remain unknown.

METHODS

Participants (N = 15,869) from the Twins Early Development Study completed self-reports of emotional symptoms, social isolation and peer victimisation at 12, 16 and 21 years old. A phenotypic cross-lagged model examined reciprocal associations between variables over time, and a genetic extension of this model examined the aetiology of the relationships between variables at each timepoint.

RESULTS

First, emotional symptoms were reciprocally and independently associated with both social isolation and peer victimisation over time, indicating that different forms of interpersonal difficulties uniquely contributed to emotional symptoms during adolescence and vice versa. Second, early peer victimisation predicted later emotional symptoms via social isolation in mid-adolescence, indicating that social isolation may constitute an intermediate pathway through which peer victimisation predicts longer-term emotional symptoms. Finally, individual differences in emotional symptoms were mostly accounted for by non-shared environmental factors at each timepoint, and both gene-environment and individual-specific environmental mechanisms were involved in the relationships between emotional symptoms and interpersonal difficulties.

CONCLUSIONS

Our study highlights the necessity to intervene early in adolescence to prevent the escalation of emotional symptoms over time and to consider social isolation and peer victimisation as important risk factors for the long-term persistence of emotional symptoms.

Developing an interpretation bias modification training task for alleviating loneliness in young people

OBJECTIVE

Loneliness is common among young people and is associated with negative health outcomes. Because loneliness is associated with a bias for interpreting social situations as threatening, cognitive bias modification for interpretation (CBM-I) training is a potential early intervention tool. We developed and delivered a single session of mental imagery enhanced digital CBM-I training, assessing feasibility, acceptability, and magnitude of change in interpretational style and loneliness.

METHOD

CBM-I training materials were developed using a co-creation approach with 18-25-year-olds with experience of loneliness. Another group of 18-25-year-olds with high loneliness received either online CBM-I (n = 29) or control (n = 27) training.

RESULTS

CBM-I training uptake and retention rates were 88% and 92%, respectively. Participants found the training acceptable. The CBM-I group showed a reduction in social threat interpretations (d = 0.77), an increase in social benign interpretations (d = 0.84), and a decrease in loneliness (d = 0.56). The control group showed a small reduction in social threat interpretations (d = 0.21), no change in social benign interpretations (d = 0.04), and an increase in loneliness (d = 0.41).

CONCLUSIONS

Interpretation biases relevant to youth loneliness may be modifiable, and CBM-I training could reduce feelings of loneliness. This informs psychological models of loneliness, and the development of CBM-I interventions targeting loneliness in young people.

The prevalence of chronic and episodic loneliness and social isolation from a longitudinal survey

Loneliness and social isolation, experienced more long-term, has been shown to increase mortality and lead to poorer health outcomes in specific cohorts. However, it is unclear what the prevalence of chronic loneliness and social isolation is, and which demographic groups are most at risk of reporting more chronic forms. A psychometrically validated classification system was used to identify people who met criteria for episodic and chronic loneliness and social isolation using the Household Income and Labour Dynamics in Australia (HILDA) survey waves 14-18. The prevalence of loneliness (overall 34%; 21% episodic, 13% chronic) far exceeded that of social isolation (overall 17%; 13% episodic, 4% chronic). There was consistency in the demographic characteristics (from age, sex, household type, income) of those who experienced loneliness and social isolation. However, people with a long-term health condition had an elevated risk of episodic loneliness (AOR 1.24, 95% CI 1.11-1.39) and a markedly higher risk of chronic loneliness (AOR 2.01, 95% CI 1.76-2.29), compared with those without a long-term health condition. Loneliness, both episodic and chronic subtypes, is more prevalent than social isolation. However, both chronic loneliness and social isolation remains neglected and poorly targeted within current practice and policy.

Loneliness During the School Years: How It Affects Learning and How Schools Can Help. THE JOURNAL OF SCHOOL HEALTH 2023;93:428-435. [PMID: 36861756 DOI: 10.1111/josh.13306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

BACKGROUND

Substantial evidence links loneliness to poor academic outcomes and poor employment prospects. Schools have been shown to be places that mitigate or aggravate loneliness, suggesting a need to consider how schools can better support youth experiencing loneliness.

METHODS

We conducted a narrative review on loneliness in childhood and adolescence to examine the literature on how loneliness changes over the school years and how it influences learning. We also examined whether there were increases in loneliness because of the COVID-19 pandemic and associated school closures, and whether schools can be places for loneliness interventions/prevention.

FINDINGS

Studies describe how loneliness becomes more prevalent during the adolescent years and why that is the case. Loneliness is associated with poor academic outcomes and poor health behaviors that impact learning or turn students away from education. Research shows that loneliness increased during the COVID-19 pandemic. Evidence suggests that creating positive social classroom environments, where teacher and classmate support are available, is crucial in combatting youth loneliness.

CONCLUSIONS

Adaptations to the school climate can be made to meet the needs of all students, reducing loneliness. Investigation of the impacts of school-based loneliness prevention/intervention is crucial.

How (Not) to Measure Loneliness: A Review of the Eight Most Commonly Used Scales

Loneliness affects well-being and has long-term negative impacts on physical and mental health, educational outcomes, and employability. Because of those current and long-term impacts, loneliness is a significant issue for which we need reliable and appropriate measurement scales. In the current paper, psychometric properties of the eight most commonly used loneliness scales are reviewed both descriptively and meta-analytically. Results suggest that for many of the scales, the psychometric properties are promising. However, for some psychometric features, especially test-retest reliability and measurement invariance, evidence is rather scarce. Most striking, however, is the fact that all of the scales included items that do not measure loneliness. Surprisingly, for many (sub)scales, this was even the case for about half of the items. Because our measures are the foundation of our research work, it is crucial to improve the way loneliness is being measured.
