Abstract Background Adolescent mental wellbeing has been declining in the United Kingdom for over a decade. Expansion of services to support the mental wellbeing of young people is a public health priority and a core component of the National Health Service’s Long-Term Plan. In this paper, we leverage secondary analysis of a very large longitudinal dataset (#BeeWell) to generate insights regarding different patterns of health behaviour, their covariates, and consequences for mental wellbeing one year later. Methods A Latent Class Analysis was conducted using data on physical activity, sleep, and eating habits collected in 2021 from 18,478 Year 8 pupils from Greater Manchester (United Kingdom) to (1) identify distinct latent classes of adolescent health behaviour; (2) establish factors likely to be associated with latent class membership; and (3) determine whether latent class membership contributes to variance in self-reported mental wellbeing one year later. Results A three-class solution was identified as an excellent fit to the data, discriminating between: the Wellness Weary (n = 2,717; 15%); the Balanced Bunch (n = 7,377; 40%); and the Green and Dream Team (n = 8,384; 45%). Several factors significantly influenced class membership. Most notably, socio-economic disadvantage and social media use were linked with less favourable health behaviour patterns, whilst cisgender heterosexual girls were likely to endorse healthier patterns. After adjusting for covariates, the Green and Dream Team reported significantly greater mental wellbeing than the Balanced Bunch one year later. However, there was no difference between the Balanced Bunch and the Wellness Weary, signalling that health behaviours may support mental wellbeing, but only among the healthiest young people. Conclusions Beyond advancements in fundamental understanding, our findings yield significant translation opportunities through their use and application in health, education, and allied professional settings designed to support young people.

Abstract Introduction The residuals approach, in which residual scores from regression models are used as a proxy for resilient functioning, offers great potential to increase understanding of resilience processes. However, its application in child and adolescent wellbeing research is limited to date. We use this approach to examine how adversity exposure impacts later wellbeing (life satisfaction, and internalising mental health difficulties) in the early-to-middle adolescence transition; whether gender and ethnic differences in resilience exist; which internal and external factors confer protective effects for resilience; and, whether the protective effect of these factors differs by gender and level of adversity exposure. Method Secondary analysis of the #BeeWell longitudinal data set (N = 12,130 adolescents, aged 12/13 at T1 and 13/14 at T2, representative of Greater Manchester, England) was undertaken, using a series of linear regressions to establish adversity indices for later wellbeing, before assessing the protective effects of internal and external factors on resilience. Results Multiple adversity factors (e.g., home material deprivation, sexuality discrimination, bullying) were found to impact later wellbeing. Girls and white adolescents presented lower levels of resilience than their peers. Internal psychological factors (self-esteem, emotional regulation, optimism) consistently conferred the strongest protective effects, but behavioural/activity factors (physical activity, sleep) also contributed to resilience. Among external factors, friendships and peer support were the most salient. Physical activity yielded stronger protective effects among boys (compared to girls). Effects of protective factors were stronger among those at lower (compared to higher) levels of adversity exposure. Conclusion The residuals approach can make a considerable contribution to our understanding of the interplay between adversity exposure and access to protective factors in determining adolescent wellbeing outcomes. Moreover, its application provides clear implications for policy and practice in terms of prevention (of adversity exposure) and intervention (to facilitate resilience).

Abstract Background Gender and sexual minority adolescents experience greater symptoms of psychological distress than their peers, but little is known about broader aspects of their wellbeing. This study examines wellbeing inequalities relating to gender and sexual identity among adolescents from Greater Manchester in the United Kingdom. Method 37,978 adolescents (aged 12–15, attending 165 secondary schools) completed surveys of life satisfaction, positive and negative affect (hedonic framework); autonomy, self-esteem, optimism, and positive relationships (eudaimonic framework); and, symptoms of distress and mental wellbeing (complete state framework). Structural correlated factors models were used to assess gender and sexual identity wellbeing inequalities. Results The magnitude of wellbeing inequalities pertaining to gender and sexual identity were routinely substantially greater than those concerning other characteristics (e.g., socio-economic disadvantage). Gender identity wellbeing inequalities followed a consistent pattern, with the largest disparities evident between gender diverse adolescents and boys. Sexual identity wellbeing inequalities also followed a consistent pattern, with the largest disparities evident between sexual minority youth (both gay/lesbian and bi/pansexual) and their heterosexual peers. Finally, variation was evident across wellbeing domains. For example, observed gender identity (boys vs. girls) and sexual identity (heterosexual vs. sexual minority) disparities were substantially greater for symptoms of distress than for mental wellbeing in the complete state model. Conclusions LGBTQ + adolescents experience lower wellbeing than their peers, and this is evident across a range of wellbeing domains. Accordingly, there is an urgent need for the prioritisation of improved prevention and intervention efforts that can better meet the needs of gender diverse and sexual minority youth, and future research should be conducted to improve understanding of the mechanisms underpinning the wellbeing inequalities observed.

Abstract 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.

BackgroundSuicide is the leading cause of death of children and young people under 35 in the UK, and suicide rates are rising in this age group. Schools are considered an appropriate and logical setting for youth suicide prevention activities, with universal, selective, and indicated approaches all demonstrating efficacy. Given that international best practice recommends suicide prevention programmes combine these approaches, and that to date this has not been done in school settings in the UK, this study aims to evaluate the feasibility of delivering a suicide prevention programme incorporating universal, selective, and indicated components in UK schools.MethodsThis study is a feasibility cluster-randomised controlled trial (RCT) of an adapted version of the Multimodal Approach to Preventing Suicide in Schools (MAPSS) programme. The programme, initially developed in Australia, involves delivering universal psychoeducation to all pupils, screening them for suicide risk, and delivering Internet-based Cognitive Behavioural Therapy (Reframe IT-UK) to those students identified as being at high-risk for suicide. The programme will be trialled in six secondary schools in Northwest England and will target Year 10 students (14- and 15-year-olds). The primary aims are to assess: 1) the acceptability and safety of delivering MAPSS in a school setting in the UK; 2) the social validity of the MAPSS programme; and 3) the feasibility of delivering a large-scale, appropriately powered, cluster-RCT and economic evaluation of this intervention in the future. Secondary aims are to assess changes over time in mental health and wellbeing outcomes.DiscussionThis study is the first to evaluate a suicide prevention programme comprising universal, selective, and indicated components in UK schools. If the programme is found to be feasible, it could be more widely tested in schools and may ultimately lead to reduced rates of suicide and suicidal behaviour in young people.

Abstract 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.

Abstract 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.

Abstract 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.

Abstract There are increasing rates of internalising difficulties, particularly anxiety and depression, being reported in children and young people in England. School-based universal prevention programmes are thought to be one way of helping tackle such difficulties. This paper describes an update to a four-arm cluster randomised controlled trial ( http://www.isrctn.com/ISRCTN16386254 ), investigating the effectiveness of three different interventions when compared to usual provision, in English primary and secondary pupils. Due to the COVID-19 pandemic, the trial was put on hold and subsequently prolonged. Data collection will now run until 2024. The key changes to the trial outlined here include clarification of the inclusion and exclusion criteria, an amended timeline reflecting changes to the recruitment period of the trial due to the COVID-19 pandemic and clarification of the data that will be included in the statistical analysis, since the second wave of the trial was disrupted due to COVID-19.

BackgroundHelp-seeking is intrinsic to efforts to manage the onset, maintenance, or escalation of mental health difficulties during adolescence. However, our understanding of adolescent help-seeking remains somewhat nebulous. A greater comprehension of help-seeking behavior from the perspective of adolescents is needed. It is also prudent to explore help-seeking behavior in the context of perceived cause for emotional distress, particularly as causal beliefs have been found to influence help-seeking behavior in adults.ObjectivesThe present study sought to categorize adolescents' experiences of help-seeking, and to examine the extent to which these categories (or “types”) of help-seeking behavior are associated with their perceptions of causal factors for emotional distress.MethodsThe data for this study were drawn from interviews conducted as part of the HeadStart Learning Programme. The sample comprised of 32 young people aged 11–12 years. Ideal-type analysis, a qualitative form of person-centered analysis, was used to construct a typology of adolescent help-seeking. Participants' help-seeking “type” was then compared with their perceived cause for emotional distress “type.”FindingsWe developed four distinct categories of help-seeking: (1) guided by others who have taken notice; (2) skeptical with unmet needs; (3) motivated and solution focused; and (4) preference for self-regulation. Simultaneously, we identified principal associations between perceived cause of emotional distress—(1) perceived lack of control; (2) unfair treatment; (3) others: their actions and judgements as the catalyst; (4) concern for self and others; and (5) self as cause—and help-seeking approaches. “Perceived lack of control” was most likely to be associated with “others who have taken notice”; “Unfair treatment” with “skeptical with unmet needs”; “others: their actions and judgements as the catalyst” with “motivated and solution focused”; “concern for self and others' with ‘guided by others who have taken notice”; finally, “self as cause” was most likely to be associated with “preference for self-regulation.”ConclusionsThis study demonstrates meaningful and distinct categories of adolescent help-seeking and offers empirical evidence to support the assertion that perceived cause for emotional distress may influence the help-seeking approaches of adolescents.

Abstract Aim Stress measurement in adolescent males is in its relative infancy, which is likely to influence the effectiveness of mental health services for this heterogeneous population. Although evidence suggests the prevalence of mental health difficulties increases during adolescence, the relationship between gender and stress measurement is less explored or understood. This review summarizes findings on gender operationalisation and stress measurement in research with adolescent males. Methods For this scoping review, six electronic databases across social and life sciences were searched using terms linked to adolescence, male, stress and research design. Articles were screened, data were extracted, and a narrative synthesis used to characterise studies by research design, adaptation of method for participants’ cultural context, operationalisation of gender, and measurement of stress. Results Searches identified 3259 citations, 95 met inclusion criteria and were reviewed. Findings suggest that research on psychological stress in adolescence is a developing field, but one that is currently dominated by Western studies. Furthermore, the results indicate that stress measurement research with adolescent males tends not to make adaptations relative to participants' gender, age, or context. Conclusions Stress research with adolescent males is lacking in scope. This review highlights the need for researchers to consider stress responses as more than a biological response, as it has been conceptualised historically. Recommendations for researchers to report research design and protocol more clearly are made to support readers to understand how stress and gender have been operationalised and measured and how this may influence research methodology. Future research should avoid conflating biological differences with gendered experience and demonstrate greater sensitivity to how gender identity may intersect with age and location to perpetuate gendered inequalities.

Trans and gender-diverse (TGD) adolescents are likely to experience poorer mental health and wellbeing than their cisgender peers. Minority stress theory has developed as a possible explanation for some of this disadvantage: factors such as increased bullying and discrimination lead to excess stress and reduced wellbeing. However, the evidence base remains limited. This study drew on secondary data analysis of the #BeeWell longitudinal cohort over 2 years (N = 26 042, aged 12–13 at time one, T1). We report two unregistered hypotheses relating to T1 (autumn 2021) data which was available at the time of stage-one submission: H1, mean differences in T1 wellbeing; H2, mean differences in T1 minority-related stressors. These are followed by two registered hypotheses relating to T2 (autumn 2022) data: H3, replication of T1 mean differences in T2 wellbeing; H4, predictions were made about the strength of the association between T1 minority-related stressors, controlling for sexuality and T2 wellbeing across T1 gender identity groups. At both time points cis-females, TGD and those who preferred not to say their gender had lower wellbeing than cis-males (CM), with the largest effect evident for the TGD group. TGD adolescents also showed the largest disadvantage (mean difference) compared with CM for minority stressors. Counter to H4 and minority stress theory, gender was not found to moderate the effect of minority stressors on later wellbeing. Our findings highlight the vulnerability of the TGD group in terms of wellbeing and minority stressors and are discussed with relevance for policy and future research.

Objectives We assess different approaches to seeking consent in research in secondary schools.Design We review evidence on seeking active versus passive parent/carer consent on participant response rates and profiles. We explore the legal and regulatory requirements governing student and parent/carer consent in the UK.Results Evidence demonstrates that requiring parent/carer active consent reduces response rates and introduces selection biases, which impact the rigour of research and hence its usefulness for assessing young people’s needs. There is no evidence on the impacts of seeking active versus passive student consent but this is likely to be marginal when researchers are directly in communication with students in schools. There is no legal requirement to seek active parent/carer consent for children’s involvement in research on non-medicinal intervention or observational studies. Such research is instead covered by common law, which indicates that it is acceptable to seek students’ own active consent when they are judged competent. General data protection regulation legislation does not change this. It is generally accepted that most secondary school students age 11+ are competent to provide their own consent for interventions though this should be assessed individually.Conclusion Allowing parent/carer opt-out rights recognises their autonomy while giving primacy to student autonomy. In the case of intervention research, most interventions are delivered at the level of the school so consent can only practically be sought from head teachers. Where interventions are individually targeted, seeking student active consent for these should be considered where feasible.

Abstract Background Adolescent mental health is a major concern and brief general self‐report measures can facilitate insight into intervention response and epidemiology via large samples. However, measures' relative content and psychometrics are unclear. Method A systematic search of systematic reviews was conducted to identify relevant measures. We searched PsycINFO, MEDLINE, EMBASE, COSMIN, Web of Science, and Google Scholar. Theoretical domains were described, and item content was coded and analysed, including via the Jaccard index to determine measure similarity. Psychometric properties were extracted and rated using the COSMIN system. Results We identified 22 measures from 19 reviews, which considered general mental health (GMH) (positive and negative aspects together), life satisfaction, quality of life (mental health subscales only), symptoms, and wellbeing. Measures were often classified inconsistently within domains at the review level. Only 25 unique indicators were found and several indicators were found across the majority of measures and domains. Most measure pairs had low Jaccard indexes, but 6.06% of measure pairs had >50% similarity (most across two domains). Measures consistently tapped mostly emotional content but tended to show thematic heterogeneity (included more than one of emotional, cognitive, behavioural, physical and social themes). Psychometric quality was generally low. Conclusions Brief adolescent GMH measures have not been developed to sufficient standards, likely limiting robust inferences. Researchers and practitioners should attend carefully to specific items included, particularly when deploying multiple measures. Key considerations, more promising measures, and future directions are highlighted. PROSPERO registration: CRD42020184350 https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020184350.

Surface speeds in Greenland's ablation zone undergo substantial variability on an annual basis which are presumed to mainly be driven by changes in sliding. Yet, meltwater-forced changes in ice–bed coupling can also produce variable deformation motion, which impacts the magnitude of sliding changes inferred from surface measurements and provides important context to flow dynamics. We examine spatiotemporal changes in deformation, sliding and surface velocities over a 2-year period using GPS and a dense network of inclinometers installed in borehole grid drilled in western Greenland's ablation zone. We find time variations in deformation motion track sliding changes through the summer and entire measurement period. A distinct spatial deformation and sliding pattern is also observed within the borehole grid which remains similar during winter and summer flow. We suggest that positively covarying sliding and deformation across seasonal timescales is characteristic of passive areas that are coupled to regions undergoing transient forcing, and the spatial patterns are consistent with variations in the local bed topography. The covarying deformation and sliding result in a 1.5–17% overestimate of sliding changes during summer compared to that inferred from surface velocity changes alone. This suggests that summer sliding increases are likely overestimated in many locations across Greenland.

Abstract Background From early adolescence, girls and women report the highest rates of emotional symptoms, and there is evidence of increased prevalence in recent years. We investigate risk factors and cumulative risk exposure (CRE) in relation to emotional symptoms among early adolescent girls. Methods We used secondary data analysis, drawing on data capturing demographic information and self-reported emotional symptoms from 8327 girls aged 11–12 years from the 2017 baseline data collection phase of the HeadStart evaluation. We used structural equation modelling to identify risk factors in relation to self-reported emotional symptoms, and collated this into a CRE index to investigate associations between CRE and emotional symptoms. Results Four risk factors were found to have a statistically significant relationship with emotional symptoms among early adolescent girls: low academic attainment, special educational needs, low family income, and caregiving responsibilities. CRE was positively associated with emotional symptoms, with a small effect size. Conclusions Results identify risk factors (outlined above) that are associated with emotional symptoms among early adolescent girls, and highlight that early adolescent girls experiencing a greater number of risk factors in their lives are likely to also experience greater emotional distress. Findings highlight the need for identification and targeted mental health intervention (e.g., individual or group counselling, approaches targeting specific symptoms), for those facing greater risk and/or with emergent symptoms.

The individualization of Not in Education, Employment, or Training (NEET) status has contributed to a culture of blame that frames adolescent boys’ transition into employment and economic independence. Drawing on Urie Bronfenbrenner’s ecological systems theory, we explored how adolescent boys categorized as “at risk” of becoming NEET engage with a school-based work-readiness intervention. We interviewed five adolescent boys aged 13–14 years about their experiences of the intervention. Using reflexive thematic analysis, three main themes were constructed: (1) challenge mediated by choice; (2) access to supportive relationships; and (3) recognizing personal development. The findings illustrate the interrelatedness of adolescent boys’ engagement with, and within, their environment; findings support a push to consider engagement as an ecological concept. We end with considerations for more ecologically sensitive approaches to work-related intervention and the assessment of adolescent boys’ “at risk” status.

The intermixed thermal and structural framework of cold firn, water-saturated firn and ice layers in Greenland's percolation zone can be challenging to penetrate with core drills. Here, we present our experiences using a hot water drill for research on the firn layer of the percolation zone. We built and deployed a lightweight and easily transportable system for drilling a transect of ~15 cm diameter boreholes through the full firn column thickness, to depths exceeding 100 m. An instrumented drill stem provides a scientific measurement of the firn properties while drilling. The system was successful at gaining rapid access to the firn column with mixed wet and cold conditions, was easily transported to the site and across the glacier surface, and required a small field crew to operate. The boreholes are well suited for in situ investigations of firn processes in Greenland percolation zone.

Abstract Background The increasing prevalence of mental health difficulties among children and young people (CYP) suggests that early intervention is vital. A comprehensive system of care and support requires the involvement of mental health professionals, including psychologists and psychiatrists, and allied professionals, including teachers, police, and youth workers. A critical starting point is the provision of effective training, in order that these professionals can better support the mental health needs of the CYP that they encounter. Objectives Given the primacy of training in the CYP mental health support system, understanding the factors that maximise potential gains and facilitate uptake is pertinent. The current review therefore located and explored qualitative research evidence, to identify the barriers and facilitators underpinning successful delivery and implementation of training focussed on the mental health of CYP, for both mental health and allied professionals. Methods A systematic review and qualitative meta-aggregation were conducted. Systematic searches were carried out using ASSIA, EMBASE, MEDLINE, NICE Evidence, PsycINFO, and Scopus databases, for papers published between 2000 and 2020. Twelve thousand four hundred forty-eight records were identified, of which 39 were eligible for review. The records were appraised for quality using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and synthesised using the qualitative meta-aggregation method. Results One hundred eighty-two raw findings were extracted from the 39 papers, which were condensed into 47 sub-categories, 19 categories, and finally 5 synthesis statements. These synthesis statements reflected the barriers and facilitators influencing the training delivery process (“support”; “content, design, and planning”), and the implementation of training into the workplace (“context”; “perceived value”; “organisational factors”). Conclusions The synthesis statements and underlying categories provide practical recommendations for those designing, delivering, or implementing CYP mental health training. Recommendations ranged from facilitating peer support during training, to the idea that training will be better implemented when perceived need is high. The review provides a robust evidence-based foundation to “common-sense” principles, drawing them into a coherent and organised framework using a synthesis method grounded in pragmatism.

Background: Universal, school-based behaviour management interventions can produce meaningful improvements in children’s behaviour and other outcomes. However, the UK evidence base for these remains limited. Objective: The objective of this trial was to investigate the impact, value for money and longer-term outcomes of the Good Behaviour Game. Study hypotheses centred on immediate impact (hypothesis 1); subgroup effects (at-risk boys, hypothesis 2); implementation effects (dosage, hypothesis 3); maintenance/sleeper effects (12- and 24-month post-intervention follow-ups, hypothesis 4); the temporal association between mental health and academic attainment (hypothesis 5); and the health economic impact of the Good Behaviour Game (hypothesis 6). Design: This was a two-group, parallel, cluster-randomised controlled trial. Primary schools (n = 77) were randomly assigned to implement the Good Behaviour Game for 2 years or continue their usual practice, after which there was a 2-year follow-up period. Setting: The trial was set in primary schools across 23 local authorities in England. Participants: Participants were children (n = 3084) aged 7–8 years attending participating schools. Intervention: The Good Behaviour Game is a universal behaviour management intervention. Its core components are classroom rules, team membership, monitoring behaviour and positive reinforcement. It is played alongside a normal classroom activity for a set time, during which children work in teams to win the game to access the agreed rewards. The Good Behaviour Game is a manualised intervention delivered by teachers who receive initial training and ongoing coaching. Main outcome measures: The measures were conduct problems (primary outcome; teacher-rated Strengths and Difficulties Questionnaire scores); emotional symptoms (teacher-rated Strengths and Difficulties Questionnaire scores); psychological well-being, peer and social support, bullying (i.e. social acceptance) and school environment (self-report Kidscreen survey results); and school absence and exclusion from school (measured using National Pupil Database records). Measures of academic attainment (reading, standardised tests), disruptive behaviour, concentration problems and prosocial behaviour (Teacher Observation of Child Adaptation Checklist scores) were also collected during the 2-year follow-up period. Results: There was no evidence that the Good Behaviour Game improved any outcomes (hypothesis 1). The only significant subgroup moderator effect identified was contrary to expectations: at-risk boys in Good Behaviour Game schools reported higher rates of bullying (hypothesis 2). The moderating effect of the amount of time spent playing the Good Behaviour Game was unclear; in the context of both moderate (≥ 1030 minutes over 2 years) and high (≥ 1348 minutes over 2 years) intervention compliance, there were significant reductions in children’s psychological well-being, but also significant reductions in their school absence (hypothesis 3). The only medium-term intervention effect was for peer and social support at 24 months, but this was in a negative direction (hypothesis 4). After disaggregating within- and between-individual effects, we found no temporal within-individual associations between children’s mental health and their academic attainment (hypothesis 5). Last, our cost–consequences analysis indicated that the Good Behaviour Game does not provide value for money (hypothesis 6). Limitations: Limitations included the post-test-only design for several secondary outcomes; suboptimal implementation dosage (mitigated by complier-average causal effect estimation); and moderate child-level attrition (18.5% for the primary outcome analysis), particularly in the post-trial follow-up period (mitigated by the use of full information maximum likelihood procedures). Future work: Questions remain regarding programme differentiation (e.g. how distinct is the Good Behaviour Game from existing behaviour management practices, and does this makes a difference in terms of its impact?) and if the Good Behaviour Game is impactful when combined with a complementary preventative intervention (as has been the case in several earlier trials). Conclusion: The Good Behaviour Game cannot be recommended based on the findings reported here. Trial registration: This trial is registered as ISRCTN64152096.

Background: Prior evidence suggests that behaviours closely related to the intervention delivered for autism are amenable to change, but it becomes more difficult when generalising treatment effects beyond that immediate context. Objectives: The objectives were (1) to test an early autism social communication intervention designed to promote child social communication change in the naturalistic contexts of both home and education, with an additive effect on overall child symptom outcomes, and (2) to conduct a mechanistic study investigating the transmission of treatment effects within and across contexts to an overall treatment effect. Design: The trial was a three-site, parallel-group, randomised controlled trial of the experimental treatment plus treatment as usual and treatment as usual alone. The primary intention-to-treat analysis used analysis of covariance. The mechanism analysis used regression models to test mediation of the primary outcome by parent–child and education staff (learning support assistant)–child social interactions. Setting: The study took place in three urban/semiurban regions in Manchester, Newcastle upon Tyne and London. Participants: Children aged 2–11 years who met the criteria for severe autism. Interventions: The Preschool Autism Communication Trial was adapted to parallel components within home and educational settings using in-person and remote delivery. Treatment as usual was the control condition. Main outcome measures: The primary outcome was autism symptoms on the Autism Diagnostic Observation schedule-2. The secondary outcomes were Brief Observation of Social Communication Change, dyadic social interaction between child and parent or learning support assistant, reported language, functional outcome and reduction in child disruptive behaviour. Outcomes were measured at baseline and at the 12-month end point in all settings; interim mechanism measurements were taken at 7 months. Results: Participants (n = 249; 122 in the PACT-G group and 127 in the treatment-as-usual group; 51 were female and 197 were male) received a median of 10 (interquartile range 8–12) sessions at home and 8 (interquartile range 5–10) sessions in an educational setting. We found no significant treatment effects on the end-point Autism Diagnostic Observation Schedule-2 primary outcome (–0.04, 95% confidence interval –0.26 to 0.18; p = 0.734), on the end-point Brief Observation of Social Communication Change secondary outcome (–0.03, 95% confidence interval –0.31 to 0.25; p = 0.85) or on language, repetitive behaviour, adaptive behaviour and child well-being. We did find significant treatment effects on dyadic interactions (increased parent synchronous response 0.54, 95% confidence interval 0.39 to 0.69; p = 0.001); child initiations with a parent (0.27, 95% confidence interval 0.12 to 0.41; p = 0.001); learning support assistant synchronous response (0.32, 95% confidence interval 0.14 to 0.49; p = 0.001); child initiations with a learning support assistant (0.21, 95% confidence interval 0.06 to 0.36; p = 0.005); and unblinded measures of improved parental well-being and child disruptive behaviour across home and educational settings. Adult (parent/learning support assistant) synchronous responsiveness in a home/education setting improved child dyadic social initiation. The child dyadic social initiation was also associated with child symptoms on researcher Brief Observation of Social Communication Change. Limitations: The delivered sessional dosage was 83% of that planned in the home setting and 67% in the educational setting, with 5.5% of home sessions and 5% of educational sessions deemed ‘unacceptable’, particularly for remote delivery. A change of therapy learning support assistant was experienced by over one-third of children by the mid-point of the trial, by another third by the end point, and by one-fifth at both points. Conclusions: The multicomponent Paediatric Autism Communication Trial – Generalised (PACT-G) treatment for a child in a home or educational setting did not produce the hypothesised improvement in child autism symptomatology or adaptive behaviour, but did produce significant improvements in proximal adult–child reciprocal dyadic communication. Future work: Future work will involve building on these results towards a further understanding of delivery options, dosage and multicomponent extension of social communication interventions for young children with autism in naturalistic settings.

Abstract Background With an increased political interest in school-based mental health education, the dominant understanding and measurement of mental health literacy (MHL) in adolescent research should be critically appraised. This systematic literature review aimed to investigate the conceptualisation and measurement of MHL in adolescent research and the extent of methodological homogeneity in the field for meta-analyses. Methods Databases (PsycINFO, EMBASE, MEDLINE, ASSIA and ERIC) and grey literature were searched (1997–2017). Included articles used the term ‘mental health literacy’ and presented self-report data for at least one MHL domain with an adolescent sample (10–19 years). Definitions, methodological and contextual data were extracted and synthesised. Results Ninety-one articles were identified. There was evidence of conceptual confusion, methodological inconsistency and a lack of measures developed and psychometrically tested with adolescents. The most commonly assessed domains were mental illness stigma and help-seeking beliefs; however, frequency of assessment varied by definition usage and study design. Recognition and knowledge of mental illnesses were assessed more frequently than help-seeking knowledge. A mental-ill health approach continues to dominate the field, with few articles assessing knowledge of mental health promotion. Conclusions MHL research with adolescent samples is increasing. Results suggest that a better understanding of what MHL means for this population is needed in order to develop reliable, valid and feasible adolescent measures, and explore mechanisms for change in improving adolescent mental health. We recommend a move away from ‘mental disorder literacy’ and towards critical ‘mental health literacy’. Future MHL research should apply integrated, culturally sensitive models of health literacy that account for life stage and acknowledge the interaction between individuals’ ability and social and contextual demands.

Research suggests that loneliness during childhood is associated with poor well-being and mental ill-health. There is a growing social and educational imperative to explore how school-based interventions can support young children’s social development. The Promoting Alternative Thinking Strategies (PATHS) curriculum is a universal school intervention focused on social and emotional learning, and it has a significant evidence based supporting its positive impact on children’s social-emotional and mental health outcomes. Yet the impact on children’s reported loneliness has not been explored. This paper presents the first large scale analyses of the impact of PATHS on reducing children’s loneliness in England. A cluster randomized controlled trial (RCT) with two arms: intervention (PATHS—23 schools) and control (usual practice—22 schools) assessed the impact of PATHS on children’s loneliness from baseline to 2-year follow-up. Two-level (school, child) multi-nomial regression models were used to assess “intention-to-treat” effects, controlling for important demographic co-variates such as gender, age, free school meal eligibility, ethnicity, and special educational needs. These analyses revealed a significant positive effect of PATHS on children’s loneliness. Furthermore, sensitivity analyses, treating loneliness as a dichotomous variable and using different cut-offs for loneliness, revealed the positive effect of PATHS was maintained and, thus, robust. This is the first RCT to demonstrate that a school-based universal social-emotional learning intervention such as PATHS can reduce loneliness in children.

Schools are increasingly encouraged to adopt evidence-based or evidence informed interventions and implement them using insights from implementation science. The literature relating to implementation of interventions in schools has focused largely on universal interventions, particularly for social and emotional learning (SEL), which are designed for all children and young people. In contrast, targeted interventions provide additional support for those pupils who may require small group or individual support over and above that provided at the universal level. To date there has been limited consideration of factors which are important for the implementation of targeted SEL interventions. Data from an exploratory case study with two schools implementing Lego therapy are used to illustrate the implementation factors relevant to this targeted intervention. Findings indicate similarities in universal and targeted intervention core components and factors but also a number of distinct elements that are important to consider when implementing Lego therapy and potentially other targeted SEL interventions. Key considerations include the interaction with the wider school system, the pivotal role of the intervention champion, and the importance of external support for problem solving and sustainability. The resulting model may inform further development of implementation frameworks for Lego therapy and other targeted SEL interventions.

Abstract Background There are increasing rates of internalising difficulties, particularly anxiety and depression, being reported in children and young people in England. School-based, universal prevention programmes are thought to be one way of helping tackle such difficulties. This protocol describes a four-arm cluster randomised controlled trial, investigating the effectiveness of three different interventions when compared to usual provision, in English primary and secondary pupils. The primary outcome for Mindfulness and Relaxation interventions is a measure of internalising difficulties, while Strategies for Safety and Wellbeing will be examined in relation to intended help-seeking. In addition to the effectiveness analysis, a process and implementation evaluation and a cost-effectiveness evaluation will be undertaken. Methods and analysis Overall, 160 primary schools and 64 secondary schools will be recruited across England. This corresponds to 17,600 participants. Measures will be collected online at baseline, 3–6 months later, and 9–12 months after the commencement of the intervention. An economic evaluation will assess the cost-effectiveness of the interventions. Moreover, a process and implementation evaluation (including a qualitative research component) will explore several aspects of implementation (fidelity, quality, dosage, reach, participant responsiveness, adaptations), social validity (acceptability, appropriateness and feasibility), and their moderating effects on the outcomes of interest, and perceived impact. Discussion This trial aims to address important questions about whether schools’ practices around the promotion of mental wellbeing and the prevention of mental health problems can: (1) be formalised into feasible and effective models of school-based support and (2) whether these practices and their effects can be sustained over time. Given the focus of these interventions on mirroring popular practice in schools and on prioritising approaches that present low-burden, high-acceptability to schools, if proved effective, and cost-effective, the findings will indicate models that are not only empirically tested but also offer high potential for widespread use and, therefore, potentially widespread benefits beyond the life of the trial.

Background: There is increased interest in early intervention and prevention of mental health difficulties during adolescence; thus, we are seeing increased efforts to optimize well-being during this epoch. Positive emotional experiences are a central component of overall well-being. However, research exploring what adolescents perceive to be the cause(s) of their emotional difficulties is lacking. Improving understanding of this issue within non-clinical adolescent groups may provide useful insight into how to develop strategies to support young people as they navigate emotional difficulties.Objectives: The aim of this research was to explore if meaningful categories of perceived cause(s) for emotional distress exist for non-clinical adolescent groups.Methods: The data for this study were drawn from interviews across 6 sites in England conducted as part of the 5-year national evaluation of the HeadStart Learning Programme. The sample comprised of 32 young people aged 11–12 years from the first annual wave of qualitative data collection in 2017. Ideal type analysis—a qualitative form of person-centered analysis—was used to construct a typology of adolescents perceived cause(s) for emotional distress.Findings: We identified five distinct categories of perceived cause: (1) perceived lack of control; (2) unfair treatment; (3) others, their actions and judgements as the catalyst; (4) concerns for self and others; and, (5) self as cause.Conclusions: Our findings illustrate that distinct categories for perceived cause of emotional distress exist among adolescents considered to be “at risk” of developing mental health difficulties, which provides a foundation for future necessary work seeking to investigate the possible link between perceived cause for emotional distress and help-seeking behavior among sub-clinical groups.

Abstract Background School-based mental health literacy (MHL) interventions are increasingly trialled outside of the country in which they were developed. However, there is a lack of published studies that qualitatively explore their cultural adaptation. This study investigated the reasons for adaptations made and suggested to a Canadian MHL curriculum (The Guide) within the English school context. Method Semi-structured interviews were conducted with 11 school staff responsible for the planning and/or implementation of The Guide across three schools in the South East of England, as part of the Education for Wellbeing (EfW) feasibility study. Transcripts were analysed using a hybrid, deductive-inductive thematic analysis. Results Adaptations made and suggested included dropping and emphasising content, and adapting language, examples and references. Most adaptations were proactive and related to The Guide's implementation methods, including developing more interactive and student-led approaches. Staff Capacity and Expertise, Timetabling, and Accessibility of Resources were identified as logistical reasons for adaptations. Philosophical reasons included Consistency of Messages, Student Characteristics, Reducing Stigma and Empowering Students, National and Local Context, and Appropriate Pedagogic Practices. Conclusion Overall, recommendations were for immediately implementable lesson plans informed by teachers' knowledge about best pedagogic practices in England. Adequate training, attended by both senior leadership and those implementing, was also emphasised. While ensuring that the core components are clear, MHL interventions should be developed with a necessary level of flexibility to accommodate contextual characteristics. Future research should ensure that adaptations are captured through process and implementation evaluations conducted alongside efficacy trials.

Abstract Background Prior evidence shows that behaviours closely related to the intervention delivered for autism are amenable to change, but it is more difficult to generalise treatment effects beyond the intervention context. We test an early autism intervention designed to promote generalisation of therapy-acquired skills into home and school contexts to improve adaptive function and reduce symptoms. A detailed mechanism study will address the process of such generalisation. Objective 1 will be to test if the PACT-G intervention improves autism symptom outcome in the home and school context of the intervention as well as in the primary outcome research setting. Objective 2 will use the mechanism analysis to test for evidence of acquired skills from intervention generalizing across contexts and producing additive effects on primary outcome. Methods/design This is a three-site, two-parallel-group, randomised controlled trial of the experimental treatment plus treatment as usual (TAU) versus TAU alone. Children aged 2–11 years (n = 244 (122 intervention/122 TAU; ~ 82/site) meeting criteria for core autism will be eligible. The experimental intervention builds on a clinic-based Pre-school Autism Communication Treatment model (PACT), delivered with the primary caregiver, combined with additional theory- and evidence-based strategies designed to enhance the generalisation of effects into naturalistic home and education contexts. The control intervention will be TAU. Primary outcome: autism symptom outcome, researcher-assessed using a standardised protocol. Secondary outcomes: autism symptoms, child interaction with parent or teacher, language and reported functional outcomes in home and school settings. Outcomes measured at baseline and 12-month endpoint in all settings with interim interaction measurements (7 months) to test treatment effect mechanisms. Primary analysis will estimate between-group difference in primary outcome using analysis of covariance with test of homogeneity of effect across age group. Mechanism analysis will use regression models to test for mediation on primary outcome by parent-child and teaching staff-child social interaction. Discussion This is an efficacy and mechanism trial of generalising evidence-based autism treatment into home and school settings. It will provide data on whether extending treatment across naturalistic contexts enhances overall effect and data on the mechanism in autism development of the generalisation of acquired developmental skills across contexts.

Introduction The prevalence of emotional difficulties in young people is increasing. This upward trend is largely accounted for by escalating symptoms of anxiety and depression. As part of a public health response, there is increasing emphasis on universal prevention programmes delivered in school settings. This protocol describes a three-arm, parallel group cluster randomised controlled trial, investigating the effectiveness and cost-effectiveness of two interventions, alongside a process and implementation evaluation, to improve mental health and well-being of Year 9 pupils in English secondary schools.Method A three-arm, parallel group cluster randomised controlled trial comparing two different interventions, the Youth Aware of Mental Health (YAM) or the Mental Health and High School Curriculum Guide (The Guide), to Usual Provision. Overall, 144 secondary schools in England will be recruited, involving 8600 Year 9 pupils. The primary outcome for YAM is depressive symptoms, and for The Guide it is intended help-seeking. These will be measured at baseline, 3–6 months and 9–12 months after the intervention commenced. Secondary outcomes measured concurrently include changes to: positive well-being, behavioural difficulties, support from school staff, stigma-related knowledge, attitudes and behaviours, and mental health first aid. An economic evaluation will assess the cost-effectiveness of the interventions, and a process and implementation evaluation (including a qualitative research component) will explore several aspects of implementation (fidelity, quality, dosage, reach, participant responsiveness, adaptations), social validity (acceptability, feasibility, utility), and their moderating effects on the outcomes of interest, and perceived impact.Ethics and dissemination This trial has been approved by the University College London Research Ethics Committee. Findings will be published in a report to the Department for Education, in peer-reviewed journals and at conferences.Trial registration number ISRCTN17631228.Protocol V1 3 January 2019. Substantial changes to the protocol will be communicated to the trials manager to relevant parties (eg, ISRCTN).

Background: Latent class analysis (LCA) can be used to identify subgroups of children with similar patterns of mental health symptoms and/or strengths. The method is becoming more commonly used in child mental health research, but there are reservations about the replicability, reliability, and validity of findings.Objective: A systematic literature review was conducted to investigate the extent to which LCA has been used to study population mental health in children, and whether replicable, reliable and valid findings have been demonstrated.Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A search of literature, published between January 1998 and December 2017, was carried out using MEDLINE, EMBASE, PsycInfo, Scopus, ERIC, ASSIA, and Google Scholar. A total of 2,748 studies were initially identified, of which 23 were eligible for review. The review examined the methods which studies had used to choose the number of mental health classes, the classes that they found, and whether there was evidence for the validity and reliability of the classes.Results: Reviewed studies used LCA to investigate both disparate mental health symptoms, and those associated with specific disorders. The corpus of studies using similar indicators was small. Differences in the criteria used to select the final LCA model were found between studies. All studies found meaningful or useful subgroups, but there were differences in the extent to which the validity and reliability of classes were explicitly demonstrated.Conclusions : LCA is a useful tool for studying and classifying child mental health at the population level. Recommendations are made to improve the application and reporting of LCA and to increase confidence in findings in the future, including use of a range of indices and criteria when enumerating classes, clear reporting of methods for replicability, and making efforts to establish the validity and reliability of identified classes.

Research with adults and older adolescents suggests a general factor may underlie both mental health difficulties and wellbeing. However, the classical bifactor model commonly used to demonstrate this general trait has recently been criticised when a unidimensional structure is not supported. Furthermore, research is lacking in this area with children and early adolescents. We present confirmatory factor analysis models to explore the structure of psychopathology and wellbeing in early adolescents, using secondary data from a large U.K. sample (N = 1982). A simple correlated factors structure fitted the data well and revealed that wellbeing was just as related to internalising as this was to externalising symptoms. The classical bifactor solution also fitted the data well but was rejected as the general factor explained only 55% of the total common variance. S-1 models were therefore used to explore general covariance in a more robust way, and revealed that a general internalising distress factor could play an important role in all item responses. Gender and income differences in mental health were also explored through invariance testing and correlations. Our findings demonstrate the importance of considering mental health difficulties and wellbeing items together, and suggestions are made for how their correspondence could be controlled for.

Although Social and Emotional Learning (SEL) is seen to benefit children and youth, evidence is largely built on summative trials of programmes, with little comparative insight into the specific approaches that underpin SEL. The current study sought to highlight a hitherto underutilized approach in identifying common SEL practices through the identification of "core components". Both instructional ("how" SEL is taught) and practice-based ("what" SEL is taught) elements were examined across 13 elementary level evidence-based programmes through a method of distillation of skills and practices. Findings showed a discrepancy between theorized SEL and identified components, consistent with emergent literature. Further, the study is the first to cross-examine practice and instruction elements, linking prevalent pedagogical approaches to specific SEL skills. The implications for core components as an approach are discussed in respect to a refinement of theory, considerations for teaching practices, and recommendations for the design of future research in SEL evaluation.

Background: Universal social and emotional learning interventions can produce significant practical improvements in children’s social skills and other outcomes. However, the UK evidence base remains limited. Objectives: To investigate the implementation, impact and cost-effectiveness of the Promoting Alternative THinking Strategies (PATHS) curriculum. Design: Cluster randomised controlled trial. Primary schools (n = 45) were randomly assigned to implement PATHS or to continue with their usual provision for 2 years. Setting: Primary schools in seven local authorities in Greater Manchester. Participants: Children (n = 5218) in Years 3–5 (aged 7–9 years) attending participating schools. Intervention: PATHS aims to promote children’s social skills via a taught curriculum, which is delivered by the class teacher, generalisation activities and techniques, and supplementary materials for parents. Schools in the usual provision group delivered the Social and Emotional Aspects of Learning programme and related interventions. Main outcome measures: Children’s social skills (primary outcome, assessed by the Social Skills Improvement System); pro-social behaviour and mental health difficulties (Strengths and Difficulties Questionnaire); psychological well-being, perceptions of peer and social support, and school environment (Kidscreen-27); exclusions, attendance and attainment (National Pupil Database records); and quality-adjusted life-years (QALYs) (Child Health Utility 9 Dimensions). A comprehensive implementation and process evaluation was undertaken, involving usual provision surveys, structured observations of PATHS lessons, interviews with school staff and parents, and focus groups with children. Results: There was tentative evidence (at a p-value of

The aims of the current study were to examine the factors affecting implementation of social and emotional aspects of learning (SEAL) small group interventions in primary schools and to explore the role of support from Local Authorities (LAs) in the implementation process. Telephone interviews were conducted with lead SEAL staff in 12 LAs across England as part of a larger national evaluation of this educational initiative. Data were transcribed and subjected to qualitative content analysis. Subsequently, a tentative model was developed to document the relationship between the nature of support provided by LAs (e.g. training events, developing/providing additional materials), factors affecting implementation at school level (e.g. school readiness, the profile of SEAL) and perceived barriers to success (e.g. misconceptions about the purpose of small group interventions). These findings are discussed in relation to the existing literature on the implementation of social-emotional initiatives and interventions in education.

This paper considers some of the major challenges facing key stakeholders, including teachers, professionals working in support services, parents and pupils, as they strive to improve services for children with social, emotional and behavioural difficulties (SEBD). For each of these challenges (working with families, low educational attainments, including pupils with SEBD in mainstream schools, transition from school to college or employment, early intervention and prevention) we review research evidence, mainly from the UK and USA, and discuss possible solutions. A key theme in the paper, discussed in the concluding section, is that governments, local authorities and schools, should use the research evidence to develop carefully planned and evidence based interventions that will lead to sustained improvements being made in the education of these vulnerable young people.
