What treatment outcomes matter in adolescent depression? A Q-study of priority profiles among mental health practitioners in the UK and Chile.

Evidence-based and person-centred care requires the measurement of treatment outcomes that matter to youth and mental health practitioners. Priorities, however, may vary not just between but also within stakeholder groups. This study used Q-methodology to explore differences in outcome priorities among mental health practitioners from two countries in relation to youth depression. Practitioners from the United Kingdom (UK) (n = 27) and Chile (n = 15) sorted 35 outcome descriptions by importance and completed brief semi-structured interviews about their sorting rationale. By-person principal component analysis (PCA) served to identify distinct priority profiles within each country sample; second-order PCA examined whether these profiles could be further reduced into cross-cultural "super profiles". We identified three UK outcome priority profiles (Reduced symptoms and enhanced well-being; improved individual coping and self-management; improved family coping and support), and two Chilean profiles (Strengthened identity and enhanced insight; symptom reduction and self-management). These could be further reduced into two cross-cultural super profiles: one prioritized outcomes related to reduced depressive symptoms and enhanced well-being; the other prioritized outcomes related to improved resilience resources within youth and families. A practitioner focus on symptom reduction aligns with a long-standing focus on symptomatic change in youth depression treatment studies, and with recent measurement recommendations. Less data and guidance are available to those practitioners who prioritize resilience outcomes. To raise the chances that such practitioners will engage in evidence-based practice and measurement-based care, measurement guidance for a broader set of outcomes may be needed.

What Should Personalised Mental Health Support Involve? Views of Young People with Lived Experience and Professionals from Eight Countries.

Research demonstrates that young people value mental health support that is tailored to their needs and preferences, rather than a "one size fits all" offer, which is often not equitably accessible (National Children's Bureau, 2021). Understanding young people's lived experiences across different sociocultural contexts is important. The aim of this research was to conduct an international qualitative study on the views of young people with lived experience and professionals, on proposed aspects of personalised support for anxiety and/or depression. Participatory action focus groups were conducted with N = 120 young people with lived experience of anxiety and/or depression (14-24 years) and with N = 63 professionals in Brazil, India, Kenya, Pakistan, Portugal, South Africa, Turkey, and the United Kingdom. Data were analysed using the rigorous and accelerated data reduction (RADaR) technique. Overall, although some country-specific differences were found in terms of what aspects of support young people found to be most important, individual preferences were considered stronger, furthering the view that support should be personalised to the needs of the individual young person. Young people experiencing anxiety and/or depression should be able to choose for themselves which aspects of support they would prefer in their own care and support plans, with families and mental health professionals providing guidance where appropriate, rather than removing the young person from the decision-making process altogether. It should also be ensured that the aspects of personalised support can be understood by young people and professionals from different contexts, including marginalised and minoritised groups and communities.

Using Progress Feedback to Enhance Treatment Outcomes: A Narrative Review.

We face increasing demand for greater access to effective routine mental health services, including telehealth. However, treatment outcomes in routine clinical practice are only about half the size of those reported in controlled trials. Progress feedback, defined as the ongoing monitoring of patients' treatment response with standardized measures, is an evidence-based practice that continues to be under-utilized in routine care. The aim of the current review is to provide a summary of the current evidence base for the use of progress feedback, its mechanisms of action and considerations for successful implementation. We reviewed ten available meta-analyses, which report small to medium overall effect sizes. The results suggest that adding feedback to a wide range of psychological and psychiatric interventions (ranging from primary care to hospitalization and crisis care) tends to enhance the effectiveness of these interventions. The strongest evidence is for patients with common mental health problems compared to those with very severe disorders. Effect sizes for not-on-track cases, a subgroup of cases that are not progressing well, are found to be somewhat stronger, especially when clinical support tools are added to the feedback. Systematic reviews and recent studies suggest potential mechanisms of action for progress feedback include focusing the clinician's attention, altering clinician expectations, providing new information, and enhancing patient-centered communication. Promising approaches to strengthen progress feedback interventions include advanced systems with signaling technology, clinical problem-solving tools, and a broader spectrum of outcome and progress measures. An overview of methodological and implementation challenges is provided, as well as suggestions for addressing these issues in future studies. We conclude that while feedback has modest effects, it is a small and affordable intervention that can potentially improve outcomes in psychological interventions. Further research into mechanisms of action and effective implementation strategies is needed.

What treatment outcomes matter most? A Q-study of outcome priority profiles among youth with lived experience of depression.

Interest in youth perspectives on what constitutes an important outcome in the treatment of depression has been growing, but limited attention has been given to heterogeneity in outcome priorities, and minority viewpoints. These are important to consider for person-centred outcome tracking in clinical practice, or when conducting clinical trials targeting specific populations. This study used Q-methodology to identify outcome priority profiles among youth with lived experience of service use for depression. A purposive sample of 28 youth (aged 16-21 years) rank-ordered 35 outcome statements by importance and completed brief semi-structured interviews eliciting their sorting rationales. By-person principal component analysis was used to identify outcome priority profiles based on all Q-sort configurations. Priority profiles were described and interpreted with reference to the qualitative interview data. Four distinct outcome priority profiles were identified: "Relieving distress and experiencing a happier emotional state"; "Learning to cope with cyclical distressing emotional states"; "Understanding and processing distressing emotional states"; and "Reduced interference of ongoing distressing emotional states with daily life". All four profiles prioritised improvements in mood and the ability to feel pleasure but differed in the level of importance assigned to learning coping skills, processing experiences, and the reduced interference of depression with life and identity. As part of a person-centered approach to care delivery, care providers should routinely engage young people in conversation and shared decision-making about the types of change they would like to prioritise and track during treatment, beyond a common core of consensus outcomes.

A systematic review of shared decision making interventions in child and youth mental health: synthesising the use of theory, intervention functions, and behaviour change techniques.

Reviews around interventions to improve shared decision making (SDM) for child and youth mental health have produced inconclusive findings on what approaches increase participation. Importantly, the previous reviews did not explore the use of theory, as well as mechanisms of change (intervention functions) and active units of change (behaviour change techniques). The aim of this review was to explore these factors and ascertain how, if at all, these contribute to SDM. Five databases were searched up until April 2020. Studies met inclusion criteria if they were: (a) an intervention to facilitate SDM; (b) aimed at children, adolescence, or young people aged up to 25, with a mental health difficulty, or their parents/guardians; and (c) included a control group. Data were extracted on patient characteristics, study design, intervention, theoretical background, intervention functions, behaviour change techniques, and SDM. Quality assessment of the studies was undertaken using the Effective Public Health Practice Project (EPHPP) quality assessment tool. Eight different interventions met inclusion criteria. The role of theory to increase SDM remains unclear. Specific intervention functions, such as 'education' on SDM and treatment options and 'environmental restructuring' using decision aids, are being used in SDM interventions, as well as 'training' for clinicians. Similarly, behaviour change techniques linked to these, such as 'adding objects to the environment', 'discussing pros/cons', and clinicians engaging in 'behavioural practice/rehearsal'. However, as most studies scored low on the quality assessment criteria, as well as a small number of studies included and a low number of behaviour change techniques utilised, links between behaviour change techniques, intervention functions and increased participation remain tentative. Intervention developers and clinicians may wish to consider specific intervention functions and behaviour change techniques to facilitate SDM.

Predictors of amounts of child and adolescent mental health service use.

The aim of this study was to build evidence about how to tailor services to meet the individual needs of young people by identifying predictors of amounts of child and adolescent mental health service use. We conducted a secondary analysis of a large administrative dataset from services in England was conducted using the Mental Health Services Data Set (years 2016-17 and 2017-18). The final sample included N = 27,362 episodes of care (periods of service use consisting of at least two attended care contacts and less than 180 days between care contacts) from 39 services. There were 50-10,855 episodes per service. The descriptive statistics for episodes of care were: Mage = 13 years, SDage = 4.71, range = 0-25 years; 13,785 or 50% male. Overall, there were high levels of heterogeneity in number of care contacts within episodes of care: M = 11.12, SD = 28.28, range = 2-1529. Certain characteristics predicted differential patterns of service use. For example, young people with substance use (beta = 6.29, 95% CI = 5.06-7.53) or eating disorders (beta = 4.30, 95% CI = 3.29-5.30) were particularly more likely to have higher levels of service use. To build on this, evidence is needed about predictors of child and adolescent mental health treatment outcome and whether the same characteristics predict levels of improvement as well as levels of service use.

Defining young people's mental health self-care: a systematic review and co-development approach.

Self-care is among the emerging types of mental health support which operate outside traditional services, although the meaning and practice of self-care for young people with mental health difficulties are currently unclear. This systematic review was pre-registered with PROSPERO (CRD42021282510) and investigated conceptualizations of self-care in academic publications which investigated or discussed self-care for young people's mental health or wellbeing. A Patient and Public Involvement (PPI) workshop facilitated young people with experience of mental health difficulties to respond to the identified concepts and co-develop a definition of self-care. Searches in PsycINFO, MEDLINE, Embase, CINAHL Plus, Scopus, Cochrane Library of Systematic Reviews, and gray literature sources resulted in 90 included publications. Content analysis indicated little conceptual consistency, with health and wellness promotion most commonly used to define self-care. The PPI workshop co-developed a definition of mental health self-care, which attendees felt should emphasize an individual process of self-awareness, self-compassion, and specific strategies to work toward emotional balance. This study highlights the gap between current academic understandings of young people's mental health self-care and young people's experience. The presented definition will enable future research to begin from an understanding of self-care which is relevant to young people with experience of mental health difficulties.

Characteristics of young people accessing recently implemented Community Forensic Child and Adolescent Mental Health Services (F:CAMHS) in England: insights from national service activity data.

Children and young people in contact with forensic child and adolescent mental health services present with more complex needs than young people in the general population. Recent policy in child and adolescent mental health has led to the implementation of new workstreams and programmes to improve service provision. This research examines the characteristics of children and young people referred to recently commissioned Community Forensic Child and Adolescent Services (F:CAMHS) and service activity during the first 24 months of service. The study is a national cohort study to describe the population and investigate service provision and access across England. Secondary data on 1311 advice cases and 1406 referrals are included in analysis. Findings show that 71.9% of the sample had accessed mainstream CAMHS before their referral, 50.9% had experienced/witnessed multiple traumatic events and 58.4% of young people presented with multiple difficulties. The results of the study highlight the complexity of the cohort and a need for interagency trauma-informed working. This is the first study to describe the characteristics of children and young people referred to Community F:CAMHS and provides valuable information on pathways and needs to inform service policy and provision.

Notes from the youth mental health field: Using movement towards goals as a potential indicator of service change and quality improvement.

The aim of this paper is to report our notes from the field on using movement toward goals at an aggregate level as an inference of service effectiveness. Analysis of routinely collected data from UK youth mental health services was conducted (N = 8,172, age M = 13.8, 67% female, 32% male) to explore the impact of including goal-based outcome data in combined calculations of standardized measures based on the principles of reliable change ("measurable change"). Due to the broad nature of standardized measures, inferred validity becomes diluted in any team or service level aggregate analysis. To make inferences that are closer to the person's interpretation of their difficulties, we argue that Idiographic Patient Reported Outcome Measures (I-PROMs) counterbalance these limitations. This is supported by our findings. The measurable change metric is the first step towards enabling national analysis of aggregated I-PROMs. I-PROMs, supplemented by standardized measures should be used to consider service evaluation.

Idiographic patient reported outcome measures (I-PROMs) for routine outcome monitoring in psychological therapies: Position paper.

Idiographic patient-reported outcome measures (I-PROMs) are a growing set of individualized tools for use in routine outcome monitoring (ROM) in psychological therapies. This paper presents a position statement on their conceptualization, use, and analysis, based on contemporary evidence and clinical practice. Four problem-based, and seven goal-based, I-PROMs, with some evidence of psychometric evaluation and use in psychotherapy, were identified. I-PROMs may be particularly valuable to the evaluation of psychological therapies because of their clinical utility and their alignment with a patient-centered approach. However, there are several challenges for I-PROMs: how to generate items in a robust manner, their measurement model, methods for establishing their reliability and validity, and the meaning of an aggregated I-PROM score. Based on the current state of the literature, we recommend that I-PROMs are used to complement nomothetic measures. Research recommendations are also made regarding the most appropriate methods for analyzing I-PROM data.

Unpacking the active ingredients of internet-based psychodynamic therapy for adolescents.

Internet-based psychodynamic psychotherapy (iPDT) for adolescents has been found to be effective for treating depression, but not much is known about its active ingredients. OBJECTIVE: To explore the techniques used in chat sessions in an iPDT program for depressed adolescents, and to investigate whether they predicted improvement in depression symptoms. METHOD: The study uses data collected from a pilot study. The iPDT consisted of 8 modules delivered over 10 weeks that included text, video, exercises, and a weekly text-based chat session with a therapeutic support worker (TSW). The participants were 23 adolescents meeting criteria for depression. The TSWs were 9 psychology master's students. A depression inventory QIDS-A17-SR was filled weekly by the participants, and a self-rated techniques inventory (MULTI-30) was filled by the TSWs after each chat session. RESULTS: Common factor techniques were the most widely used techniques in the chat sessions. Both common factors and psychodynamic techniques predicted improvement in depression, with psychodynamic techniques predicting improvement at the following week. CBT techniques were also used but did not predict improvement in depression. CONCLUSION: iPDT seem to work in line with theory, where the mechanisms thought to be important for change in treatment were predictive of outcome.

Predictors of child and adolescent mental health treatment outcome.

BACKGROUND: To examine the predictors of treatment outcome or improvement in mental health difficulties for young people accessing child and adolescent mental health services. METHODS: We conducted a secondary analysis of routinely collected data from services in England using the Mental Health Services Data Set. We conducted multilevel regressions on N = 5907 episodes from 14 services (Mage = 13.76 years, SDage = 2.45, range = 8-25 years; 3540 or 59.93% female) with complete information on mental health difficulties at baseline. We conduct similar analyses on N = 1805 episodes from 10 services (Mage = 13.59 years, SDage = 2.33, range = 8-24 years; 1120 or 62.05% female) also with complete information on mental health difficulties at follow up. RESULTS: Girls had higher levels of mental health difficulties at baseline than boys (ß = 0.28, 95% CI = 0.24-0.32). Young people with higher levels of mental health difficulties at baseline also had higher levels of deterioration in mental health difficulties at follow up (ß = 0.72, 95% CI = 0.67-0.76), and girls had higher levels of deterioration in mental health difficulties at follow up than boys (ß = 0.09, 95% CI = 0.03-0.16). Young people with social anxiety, panic disorder, low mood, or self-harm had higher levels of mental health difficulties at baseline and of deterioration in mental health difficulties at follow up compared to young people without these presenting problems. CONCLUSIONS: Services seeing higher proportions of young people with higher levels of mental health difficulties at baseline, social anxiety, panic disorder, low mood, or self-harm may be expected to show lower levels of improvement in mental health difficulties at follow up.

Applying behaviour change theory to understand the barriers to implementing routine outcome monitoring.

BACKGROUND: Routine outcome monitoring (ROM) is a valuable tool for monitoring client progress and pre-empting deterioration, however, there is considerable variation in how data are collected and recorded and uptake in clinical practice remains low. The aim of this study was to develop a self-report measure of practitioner attitudes to ROM in order to better understand the barriers to successful implementation in Child and Adolescent Mental Health Services (CAMHS). METHODS: An anonymous survey was completed by 184 CAMHS practitioners in the United Kingdom. The survey was designed using the Capability, Opportunity, and Motivation Model of Behaviour (COM-B). Practitioners who reported using ROM frequently in their clinical work (53%) were compared to those who used ROM infrequently (47%) across dimensions of the COM-B survey subscales. RESULTS: Confirmatory factor analysis confirmed the proposed four-factor structure, showing acceptable model fit, with high factor loadings and good reliability for all subscales. Frequent users of ROM exhibited significantly higher psychological capability, physical opportunity, social opportunity, and motivation, compared to infrequent users F (4, 140) = 14.76, p < .0001; Pillai's Trace = .297, partial η2 = .30. Results highlight several barriers to ROM, including the belief that there is not a strong evidence base for ROM, not receiving external training, and not discussing feedback and outcome data in supervision. IMPLICATIONS: In the hope of improving the successful implementation of ROM, this research provides an evidence-based tool for assessing practitioners' attitudes to ROM, which map on to intervention functions and represent targets for future implementation efforts. PRACTITIONER POINTS: The value of routine outcome monitoring (ROM) as a means to measure client progress and to elevate the efficiency and quality of mental health care is well-documented in the research literature, however, uptake in practice remains relatively low. This study applied behaviour change theory to develop a psychometrically sound self-report measure of practitioners' perspectives and practices to understand the barriers to implementation in child and adolescent mental health services in the United Kingdom. The complex and multifaceted nature of the barriers to implementation requires multilevel behaviour change strategies at the client, clinician, and organisational level. Recommendations for practice include the need for integrated, multilevel strategies aimed at improving practitioners' capabilities and motivations, strong organisational leadership and a culture of data gathering and sharing, and implementation interventions, which are tailored to target local barriers.

Are We Comparing Apples with Oranges? Assessing Improvement Across Symptoms, Functioning, and Goal Progress for Adolescent Anxiety and Depression.

Strategies for comparing routinely collected outcome data across services or systems include focusing on a common indicator (e.g., symptom change) or aggregating results from different measures or outcomes into a comparable core metric. The implications of either approach for judging treatment success are not fully understood. This study drew on naturalistic outcome data from 1641 adolescents with moderate or severe anxiety and/or depression symptoms who received routine specialist care across 60 mental health services in England. The study compared rates of meaningful improvement between the domains of internalizing symptoms, functioning, and progress towards self-defined goals. Consistent cross-domain improvement was observed in only 15.6% of cases. Close to one in four (24.0%) young people with reliably improved symptoms reported no reliable improvement in functioning. Inversely, one in three (34.8%) young people reported meaningful goal progress but no reliable symptom improvement. Monitoring systems that focus exclusively on symptom change risk over- or under-estimating actual impact, while aggregating different outcomes into a single metric can mask informative differences in the number and type of outcomes showing improvement. A move towards harmonized outcome measurement approaches across multiple domains is needed to ensure fair and meaningful comparisons.

How to manage endings in unsuccessful therapy: A qualitative comparison of youth and clinician perspectives.

Background: Approximately half of those who access child and adolescent mental health services do not show measurable improvement in symptoms. This study aimed to provide practice recommendations for managing treatment endings, particularly when outcomes have not improved. Method: Semi-structured interviews were carried out with 26 young people with a history of anxiety and/or depression along with 7 roundtable sessions with 52 mental health clinicians. Data were analyzed using Framework Analysis. Results: A common experience for young people when outcomes did not improve was a poor experience of the treatment ending, which often resulted in setbacks in their mental health and feelings of loss and abandonment. Clinicians agreed that ending was hard for young people and reported that they found managing ending hard on a personal and professional level. This was compounded by unrealistically high public expectations about the impact of therapy on outcomes and trying to strike a balance between fostering hope and managing expectations, within a context of inflexible service structures and resource constraint. Implications: Recommendations include establishing expectations from the outset and a shared understanding of what outcomes matter most to the young person. This can be achieved through communicating honestly about likely outcomes, while also providing hope.

Youth and professional perspectives of mental health resources across eight countries.

Introduction: Youth mental health support and services vary across sociocultural contexts. It is important to capture the perspectives of youth with lived experiences for planning needs-led interventions and services, especially in Global South Countries (GSC), with limited specialist resources and representative literature. Methods: The aim was to establish how youth with lived experiences of anxiety and depression viewed external support in different countries, and how these views were juxtaposed with those of professionals. We involved 121 youth aged 14-24 years and 62 professionals from different disciplines in eight countries, predominantly from the Global South. Two youth and one professional focus group was facilitated in each country. The data were analysed through a codebook thematic approach. Results: Youth across all countries largely valued informal support from family, peers and community, whilst those from GSC had limited access to structural support. They related lived experiences to therapeutic engagement and processes, in contrast with professionals who focused on outcomes and service delivery. Mental health awareness and integration of interventions with social support were considered essential by both youth and professionals, especially in disadvantaged communities. Conclusion: The mental health needs of youth in disadvantaged GSC communities can be best met through multi-modal interventions addressing these needs across their socioecology and positioned within a stepped care model. Youth with lived experiences should be involved in service planning, implementation and monitoring.

The role of mental health symptomology and quality of life in predicting referrals to special child and adolescent mental health services.

BACKGROUND: Children and adolescents' mental health problems have been largely assessed with conventional symptom scales, for example, Strengths and Difficulties Questionnaire (SDQ) given that it is one of the mostly widely used measures in specialist Child and Adolescent Mental Health Services (CAMHS). However, this emphasis on symptom scales might have missed some important features of the mental health challenges that children and young people experience including day to day functioning and life satisfaction aspect (i.e. qualify of life). METHOD: The study examined longitudinal association between a young person's self-perceptions of quality of life and mental health difficulties and referral to specialist CAMHS service using a population cohort study (Targeted Mental Health in Schools service data) nested within a large-scale linkage between school (National Pupil Data base) and child mental health service administrative data (South London and Maudsley NHS Foundation Trust children and adolescent mental health services health records). Cox proportional hazard regression to estimate crude and adjusted hazard ratios (HRs) for the association between participant psychopathology, and incidence of CAMHS referral. RESULTS: Pupils experiencing more behavioural difficulties, had an increased incidence of CAMHS referral (adjusted hazard ratio 1.1, 95% confidence interval 1.0-1.2). However, pupils who reported higher health related quality of life had a lower incidence of CAMHS referral over the follow-up period (adjusted hazard hario 0.94, 95% confidence interval 0.9-0.98). CONCLUSION: Children and young people's perception of their quality of life should be considered at the stages of a clinical needs assessment.

Early impacts of the COVID-19 pandemic on mental health care and on people with mental health conditions: framework synthesis of international experiences and responses.

PURPOSE: The COVID-19 pandemic has many potential impacts on people with mental health conditions and on mental health care, including direct consequences of infection, effects of infection control measures and subsequent societal changes. We aimed to map early impacts of the pandemic on people with pre-existing mental health conditions and services they use, and to identify individual and service-level strategies adopted to manage these. METHODS: We searched for relevant material in the public domain published before 30 April 2020, including papers in scientific and professional journals, published first person accounts, media articles, and publications by governments, charities and professional associations. Search languages were English, French, German, Italian, Spanish, and Mandarin Chinese. Relevant content was retrieved and summarised via a rapid qualitative framework synthesis approach. RESULTS: We found 872 eligible sources from 28 countries. Most documented observations and experiences rather than reporting research data. We found many reports of deteriorations in symptoms, and of impacts of loneliness and social isolation and of lack of access to services and resources, but sometimes also of resilience, effective self-management and peer support. Immediate service challenges related to controlling infection, especially in inpatient and residential settings, and establishing remote working, especially in the community. We summarise reports of swiftly implemented adaptations and innovations, but also of pressing ethical challenges and concerns for the future. CONCLUSION: Our analysis captures the range of stakeholder perspectives and experiences publicly reported in the early stages of the COVID-19 pandemic in several countries. We identify potential foci for service planning and research.

A scoping review and assessment of essential elements of shared decision-making of parent-involved interventions in child and adolescent mental health.

Parents play a critical role in child and adolescent mental health care and treatment. With the increasing implementation of shared decision-making (SDM) across health settings, there is a growing need to understand the decision support interventions used to promote SDM in child and adolescent mental health services (CAMHS). The overall aim of this review is to identify and examine the existing decision support interventions available for parents. A broad search was conducted using the key concepts "shared decision-making", "parents" and "child and adolescent mental health". Five electronic databases were searched: PsycInfo, Embase, Medline, Web of Science and the Cochrane Library. In addition to these relevant databases, we searched the Ottawa's Inventory of Decision Aids, Children's Hospital of Eastern Ontario website, Google, Google Play and known CAMHS' websites. The search identified 23 interventions available for use with parents. These interventions targeted parents providing care for children with ADHD, ASD, emotional and behavioural problems including depression (EBD), self-harm or universal mental health care. Various modalities including face-to-face, digital and paper-based versions were adopted. The majority of the interventions were able to "present options" (87%) and "discuss the pros and cons" (83%) of treatment. Time, accessibility and appropriateness of the intervention emerged as factors influencing usage and implementation of interventions. Our findings suggest that SDM interventions involving parents have been implemented differently across various presenting mental health difficulties in CAMHS. This review brings awareness of existing parent-involved interventions and has implications for the development, implementation and usage of new interventions.

Effectiveness of current psychological interventions to improve emotion regulation in youth: a meta-analysis.

BACKGROUND: Research investigating the role of emotion regulation (ER) in the development and treatment of psychopathology has increased in recent years. Evidence suggests that an increased focus on ER in treatment can improve existing interventions. Most ER research has neglected young people, therefore the present meta-analysis summarizes the evidence for existing psychosocial intervention and their effectiveness to improve ER in youth. A systematic review and meta-analysis was conducted according to the PRISMA guidelines. Twenty-one randomized-control-trials (RCTs) assessed changes in ER following a psychological intervention in youth exhibiting various psychopathological symptoms. We found moderate effect sizes for current interventions to decrease emotion dysregulation in youth (g = - 0.46) and small effect sizes to improve emotion regulation (g = 0.36). Significant differences between studies including intervention components, ER measures and populations studied resulted in large heterogeneity. This is the first meta-analysis that summarizes the effectiveness for existing interventions to improve ER in youth. The results suggest that interventions can enhance ER in youth, and that these improvements correlate with improvements in psychopathology. More RCTs including larger sample sizes, different age groups and psychopathologies are needed to increase our understanding of what works for who and when.
