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.

Identifying characteristics of adolescents with persistent loneliness during COVID-19: A multi-country eight-wave longitudinal study.

Background: Elevated loneliness experiences characterise young people. While loneliness at this developmental juncture may emerge from age-typical upheaval in social relationships, there is little data on the extent to which young people experience high and persistent levels of loneliness, and importantly, who is most vulnerable to these experiences. Using the widespread social restrictions associated with the COVID-19 pandemic, which precipitated loneliness in many, we aimed to examine adolescents' loneliness profiles across time and the demographic predictors (age, sex, and country) of more severe trajectories. Methods: Participants aged 12-18 years, recruited into a multi-wave study (N = 1039) across three sites (UK, Israel, and India) completed a 3-item loneliness measure fortnightly across 8 timepoints during the pandemic. Results: Latent class growth analysis suggested 5 distinct trajectories: (1) low stable (33%), (2) low increasing (19%), (3) moderate decreasing (17%), (4) moderate stable (23%), and (5) high increasing (8%). Females and older adolescents were more likely to experience persistently high loneliness. Conclusions: These findings indicate a need for interventions to reduce loneliness in adolescents as we emerge from the pandemic, particularly for those groups identified as being at highest risk.

Sport Participation for Academic Success: Evidence From the Longitudinal Study of Australian Children.

BACKGROUND: We aimed to identify long-term patterns of sport participation (overall, team, and individual sport) from childhood into adolescence, and to examine the association between these patterns and academic outcomes. METHODS: This cohort study used data from the Longitudinal Study of Australian Children in wave 3 (4-5 y) to wave 9 (20-21 y). The participants were a nationally representative sample of 4241 children. We conducted latent class analyses to identify sport participation trajectories and assessed the association between these trajectories and academic outcomes. RESULTS: Continued sport participation was associated with lower odds of being absent from school (OR = 0.44; 95% confidence intervals [CIs], 0.26 to 0.74), better performance on attention (B = -0.010; 95% CIs, -0.019 to -0.002) and working memory (B = -0.013; 95% CIs, -0.023 to -0.003), higher numeracy (B = 20.21; 95% CIs, 14.56 to 25.86) and literacy scores (B = 9.42; 95% CIs, 2.82 to 16.02), higher end of school academic performance (B = 3.28; 95% CIs, 1.47 to 5.09), and higher odds of studying at university (OR = 1.78; 95% CIs, 1.32 to 2.40). Team sport participation was associated with reduced absenteeism, better performance on attention and working memory, and being awarded the Higher School Certificate. Whereas individual sport participation was associated with higher literacy scores and end of school academic performance. CONCLUSIONS: Team and individual sport participation both benefit academic outcomes, but differently. Given the decline in sport participation during adolescence, these findings highlight the need to develop educational policies to establish an environment that promotes sport participation, which in turn could improve academic outcomes.

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.

Examining the impact of a universal social and emotional learning intervention (Passport) on internalising symptoms and other outcomes among children, compared to the usual school curriculum: study protocol for a school-based cluster randomised trial.

BACKGROUND: School-based universal social and emotional learning (SEL) interventions implemented during the transition to adolescence may be efficacious in preventing the development of mental health difficulties. This protocol describes a two-arm parallel cluster randomised controlled trial to investigate the impact of a universal SEL intervention (Passport, compared to usual provision) on internalising symptoms (primary outcome), emotion regulation, well-being, loneliness, social support, bullying, academic attainment, and health-related quality of life in English primary school pupils aged 9-11 years. A developer-led trial demonstrated the feasibility, acceptability, and utility of Passport; this will be the first independent trial. METHODS: Sixty primary schools will be recruited across the Greater Manchester city region and surrounding areas, involving 2400 pupils aged 8-9 at baseline. Schools will be allocated to the intervention arm to implement Passport over 18 weekly sessions or to the control arm to implement the usual school curriculum. Random allocation will be at school level following completion of baseline measures, with minimisation to ensure balance across trial arms in school size and free school meal eligibility. Measures will be collected at baseline, post-intervention (12 months post-baseline), and at 12 months follow-up (24 months post-baseline). The primary outcome analysis (intervention effects on internalising symptoms at post-intervention) will comprise a two-level (school, child) hierarchical linear model, following the intention-to-treat principle. Additional analyses will be undertaken to assess intervention effects on secondary outcomes, maintenance effects for all outcomes, intervention compliance moderator effects, subgroup moderator effects, and mechanisms underpinning intervention effects on the primary outcome. A mixed-methods implementation and process evaluation will examine factors that influence implementation, and a health economic evaluation will assess the cost-effectiveness of the intervention. DISCUSSION: Findings will provide educators with crucial knowledge of whether and how increasing emotion regulation through a universal intervention impacts internalising symptoms and a range of related outcomes. Findings will also inform policy related to the promotion of mental health among children and young people. If the intervention is found to be efficacious in reducing internalising symptoms and is also cost-effective, it may offer high potential as a preventative intervention for widespread implementation.

Reducing loneliness in the community. More Together ('Flere i Fællesskaber')-a complex intervention in Denmark.

The mounting evidence that loneliness is a determinant of poor health and well-being underpins the need for effective interventions and community action. 'More Together' (MoTo) is a large-scale, complex, multi-component and multi-level intervention for community change that addresses loneliness among young people and older adults in Silkeborg Municipality, Denmark. The intervention is inspired by the Collective Impact framework, and it is practice driven and rooted in an extensive cross-sector partnership. This article outlines (i) the organization of the cross-sector partnership, (ii) the structure of the intervention programme, (iii) the key components and activities of the programme and, finally, (iv) the intervention setting and target population. MoTo aims to create new ways to develop, implement and evaluate loneliness interventions. Experiences gained from MoTo hold the potential to transform our understanding of loneliness interventions and may inform and guide future interventions.

Advancing loneliness and social isolation as global health challenges: taking three priority actions.

Loneliness and social isolation have been identified as critical global health issues in the aftermath of the coronavirus disease 2019 (COVID-19) crisis. While there is robust scientific evidence demonstrating the impact of loneliness and social isolation on health outcomes and mortality, there are fundamental issues to resolve so that health authorities, decision makers, and practitioners worldwide are informed and aligned with the latest evidence. Three priority actions are posited to achieve a wider and more substantial impact on loneliness and social isolation. They are 1) strengthening the evidence base; 2) adopting a whole-of-systems approach; 3) developing policy support for governments worldwide. These priority actions are essential to reduce the pervasive impact of loneliness and social isolation as social determinants of health.

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.

A shared love: reciprocity and hopefulness in romantic relationships of young adults with chronic pain.

Introduction: Chronic pain (≥3 months) creates pain-related challenges that may negatively affect how young adults perceive themselves, and, indeed, they often report feeling different compared to peers and prospective romantic partners. Most studies of romantic relationships in young adults living with a long-term condition (including pain), do not consider the perspective of their partner. We present the findings of a qualitative, exploratory interview study (Phase 2 of a mixed methods study). This qualitative phase aimed to explore how young adults with chronic pain and their partners navigate romantic relationships. We focused on how young adults perceive and experience their romantic relationships and the impact, challenges, and benefits associated with living with chronic pain. Methods: This study used remote (videoconferencing) photo-elicitation interviews with a convenience sample of young adults with chronic pain (aged 18-25 years, UK and Canada) and their partners. Recruitment occurred via social media, pain-related websites and organizations, and professional networks. Five young adults with chronic pain from the UK and Canada formed the e-Advisory Group and provided detailed advice throughout the study. Data analysis used the principles of inductive reflexive thematic analysis to explore the dimensions and meaning of romantic relationships from the views of young adults with chronic pain and their romantic partners. Findings: Sixteen young adults participated (seven couples plus two young adults with pain who were interviewed without their partner). The young adults with chronic pain were ages 18-24 years (mean 21.88 years, SD 2.23). Four major interpretive themes were generated: Kindred spirits-we just sort of work; Loving in everyday acts-it's not above and beyond, it's concerned supportiveness; It's OK to be vulnerable with each other-we can talk it through; and You can't see over the horizon-hopes and fears for the future. Discussion: Hopefulness and reciprocity were key to the stories shared by the young adults in the current study. Despite the challenges and limitations imposed by chronic pain, their relationships were characterized by partnership and reciprocity, and they were able to be vulnerable with each other and offer each other support.

A Rose by any Other Name? Using Core Components to Categorize Social and Emotional Learning Provision.

Although social and emotional learning (SEL) benefits children and youth worldwide, classifying a program as SEL is insufficient to capture its variability of content. There is currently little to aid in identifying specific program content so that foci may be identified (e.g., self-management skills vs. social skills). This gap poses a difficulty for researchers attempting to address heterogeneity in SEL research and practitioners who want to select programs best suited for their contexts. This paper begins to address these concerns by extracting and contrasting 'core components' of interventions within an identified shortlist of 13 universal, elementary evidence-based programs through a distillation method using the often cited 'five core competency' model from CASEL (Collaborative for Academic, Social, and Emotional Learning). Results showed that CASEL's core competencies are represented across short-listed programs. However, almost all programs had identifiable foci, targeting a subset of skills. Accordingly, the use of 'core components' is recommended as a method for offering more nuance in SEL classification for programs beyond the current study, with implications for program implementation and the design of future research in SEL evaluation.

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.

Neighbourhood effects on loneliness among adolescents.

BACKGROUND: Loneliness is a growing public health concern, but little is known about how place affects loneliness, especially during adolescence. This is the first study to examine the influence of neighbourhoods on loneliness in early-to-mid adolescence. METHODS: Baseline data from the #BeeWell cohort study in Greater Manchester (England), including 36 141 adolescents (aged 12-15 years) across 1590 neighbourhoods, were linked to neighbourhood characteristics using administrative data at the level of lower super output areas and analysed using multilevel regression. RESULTS: Neighbourhood differences explained 1.18% of the variation in loneliness. Ethnic, gender and sexual orientation inequalities in loneliness varied across neighbourhoods. Several neighbourhood characteristics predicted loneliness at the individual level, including skills deprivation among children and young people, lower population density and perceptions of the local area (feeling safe; trust in local people; feeling supported by local people; seeing neighbours as helpful; the availability of good places to spend free time). Finally, a longer distance from home to school was associated with significantly higher loneliness. CONCLUSIONS: Neighbourhoods account for a small but significant proportion of the variation in adolescent loneliness, with some neighbourhood characteristics predicting loneliness at the individual level, and loneliness disparities for some groups differing across neighbourhoods.

Reformed child and adolescent mental health services in a devolved healthcare system: a mixed-methods case study of an implementation site.

Background: Efforts are being made to reform and reconceptualise children and young people's (CYP) mental health services. This is in response to a rapid increase in mental health difficulties in this population, and the shortcomings of current service provision. The present study seeks to comprehensively evaluate the local implementation of the THRIVE Framework for System Change in Greater Manchester, UK (GM i-THRIVE) from 2018 to 2021. The framework was designed to change the way mental health is perceived, and subsequently how support is allocated. The current study focusses on the implementation of the framework's principles into CYP mental health support in the region. Methods: The study comprised three methodological components, beginning with examination of the GM i-THRIVE implementation plan and self-assessment questionnaire measure using the Quality Implementation Tool. This was to provide a wider backdrop of implementation method adequacy to the rest of the study's findings. Subsequently, evaluation measures completed by professionals across Greater Manchester were examined to establish implementation progress, before corroborating key items from this measure with thematically analysed interview data from six CYP (13-22 years) who recently received mental health support in the region. Levels of agreement between staff and CYP were examined. Results: GM i-THRIVE's implementation plan and self-assessment measure were respectively deemed a strong guiding foundation, and a suitable way of evaluating implementation progress. Every principle within the self-assessment measure demonstrated closer alignment with the THRIVE Framework as time progressed. Two themes were developed from the qualitative interview data, each overarching four subthemes: (1) Qualities of the service: information and decision sharing; communication and continuity; needs-based support; compassion and trust, and (2) The mental health journey: beginnings; endings; waiting; satisfaction with support. A good level of agreement between CYP testimony and staff progress reports was found. Conclusions: Findings suggested that the experiences of the CYP in the sample, who were interviewed in the spring to summer period of 2022, were overwhelmingly positive. The rich insights into mental health support offered by the young participants lead us to recommend continued qualitative research with service-users as GM i-THRIVE's embedding period continues, with focus on representing a wide range of experiences in future research samples. Methodological limitations were explored, including the extent to which true cross-references could be made between professional and CYP accounts.

Child and adolescent mental health services in a devolved healthcare system: a qualitative exploration of sustainable practices.

BACKGROUND: The transference of research evidence into routine healthcare practice remains poorly understood. This includes understanding the prerequisites of longer-term viability. The present study investigated the sustainable practices of GM i-THRIVE, a programme which reconceptualizes mental health services for children and young people (CYP) in Greater Manchester, United Kingdom. We aimed to establish whether a sustainable future was likely, and to identify areas of focus to improve that likelihood. METHODS: The NHS Sustainability Model, typically completed as a questionnaire measure, was converted into interview questions. The responses of nine professionals, from a variety of roles across the CYP mental health workforce, were explored using inductive thematic framework analysis. Selected participants completed the original questionnaire. RESULTS: Five themes (communication; support; barriers to implementation; past, present, and future: the implementation journey; and the nuances of GM i-THRIVE) and 21 subthemes formed the final thematic framework. Relationships with senior leaders and with colleagues across the workforce were seen as important. Leaders' roles in providing meaning and fit were emphasized. Whilst training delivered the programme's aims well, monitoring its dissemination was challenging. Widespread issues with dedicating sufficient time to implementation were raised. The flexibility of the programme, which can be applied in multiple ways, was discussed positively. This flexibility links to the idea of GM i-THRIVE as a mindset change, and the uniqueness of this style of intervention was discussed. To varying degrees, themes were supported by responses to the quantitative measure, although several limitations to the use of the questionnaire were discovered. Consequently, they were used to infer conclusions to a lesser degree than originally intended. CONCLUSIONS: Professionals involved with GM i-THRIVE reported many elements that indicate a positive future for the programme. However, they suggested that more attention should be given to embedding the core concepts of the model at the current stage of implementation. Limitations relating to its use within our study are discussed, but we conclude that the NHS Sustainability Model is a suitable way of guiding qualitative implementation research. It is especially valuable for localized interventions. The constraints of our small sample size on transferability are considered.

Barriers and facilitators to training delivery and subsequent implementation of a localised child and adolescent mental health initiative: a qualitative content analysis.

BACKGROUND: Ensuring that children and young people (CYP) can obtain mental health support from a broad variety of sources is of upmost importance. This is especially true given the increasing prevalence of mental health difficulties in this population, and the associated challenges with receiving support from specialised healthcare services. Equipping professionals, from a wide range of sectors, with the skills needed to provide this support is a vital starting point. This study explored the experiences of professionals who had participated in CYP mental health training modules that related directly to the local implementation of the THRIVE Framework for System Change in Greater Manchester, UK (GM i-THRIVE) to establish the perceived barriers and facilitators behind the implementation of this training programme. METHODS: Directed qualitative content analysis of semi-structured interview data from nine CYP-facing professionals was conducted. Both the interview schedule and initial deductive coding strategy were developed using the findings of a systematic literature review by the authors, that was conducted to explore wider CYP mental health training experiences. This methodology was used to establish the presence or absence of these findings within GM i-THRIVE, before generating tailored recommendations for their training programme. RESULTS: When the interview data were coded and analysed, a strong level of thematic similarity with the authors' review was found. However, we deduced that the emergence of additional themes might reflect the contextual uniqueness of GM i-THRIVE, that is likely to be further compounded by the COVID-19 pandemic. Six recommendations were made for further improvement. These included the facilitation of unstructured peer interaction during training, and ensuring that jargon and key words are fully clarified. CONCLUSIONS: Methodological limitations, guidance for usage, and potential applications of the study's findings are explored. Whilst the findings were largely akin to those of the review, subtle yet important differences were found. These are likely to reflect the nuances of the training programme discussed, however, we tentatively suggest that our findings are transferable to similar training interventions. This study provides a valuable example of how qualitative evidence syntheses can be used to aid study design and analysis: an underused approach.

School Feeding to Improve Cognitive Performance in Disadvantaged Children: A 3-Arm Parallel Controlled Trial in Northwest Pakistan.

Malnutrition is associated with reduced learning aptitude and growth during childhood. We examined the impact of providing two school lunch variants, a standard school meal (school feeding, n = 70), or the standard meal with additional micronutrients (school feeding + micronutrient powder (MNP), n = 70), in children attending two schools in northwest Pakistan. A third local government school, where no lunch was provided (no school feeding, n = 70), served as the control. The primary outcome, cognitive function, was assessed using the Raven's Coloured Progressive Matrices (RCPM) test, alongside haemoglobin, at three-time points: T1 (baseline, before the initiation of the school lunch programme), T2 and T3 (5 and 12 months, respectively, after the introduction of the school lunch). Data were analysed using linear mixed-effects models to contrast between trial groups, the changes from T1 to T2 and T3. Adjusted for T1 and other co-variates, improvements in the RCPM scores were significantly greater in the school feeding group at T2 (b = 1.61, (95% CI = 0.71-2.52), t = 3.52, p = 0.001) and T3 (b = 1.28, (95% CI = 0.22-2.35), t = 2.38, p = 0.019) compared with no school feeding. In addition, at T2 (b = 1.63, (95% CI = -0.10-3.37), t = 1.86, p = 0.065), there were no significant differences between school feeding + MNP and no school feeding groups. However, improvements in the RCPM scores were significantly greater in the school feeding + MNP group at T3 (b = 2.35, (95% CI = 0.51-4.20), t = 2.53, p = 0.013) compared with no school feeding. The findings indicate an improvement in cognitive performance in children who received a school meal with and without MNP, over a 12-month period. Currently there is no operational school feeding programme at the national or provincial level in Pakistan. Our findings, therefore, highlight the need for school feeding programmes to improve learning opportunities for children from underprivileged communities.

Getting the pieces to fit: NHS and third sector collaboration to enhance crisis mental health service provision for young people.

BACKGROUND: The increase in demand for young people's mental health services has been met by a growth of co-located mental health service provision in the NHS and third sector. This research explores the benefits and challenges of the NHS collaborating with a charity to provide a step-down crisis mental health service for young people in Greater Manchester, and suggests how the collaboration between the NHS and third sector may be improved for future projects. METHODS: Working from a critical realist paradigm, this qualitative case study utilised thematic analysis of 9 in-depth interviews with operational stakeholders from 3 operational layers, to explore insiders' perspectives of the benefits and challenges of collaboration between the NHS and third sector in the context of the 'Safe Zones' initiative. RESULTS: Themes relating to perceived benefits of collaboration were: doing things differently, flexibility, a hybrid approach, shared expertise, and shared learning. These were counterbalanced by perceived challenges: getting the pieces to fit, obtaining a shared vision, geography, lack of referrals, and timing. The importance of effective communication (e.g. of shared vision, standard operating procedures, key performance indicators) was noted as central to addressing challenges and reaping benefits. CONCLUSIONS: NHS and third sector collaboration can yield a range of benefits, some of which can mitigate against the perceived inflexibility and restrictive nature of usual mental health service provision, thereby providing a vehicle for innovation in step-down crisis care for young people.

Loneliness During the School Years: How It Affects Learning and How Schools Can Help.

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.
