Emotional competence self-help mobile phone app versus cognitive behavioural self-help app versus self-monitoring app to promote mental wellbeing in healthy young adults (ECoWeB PROMOTE): an international, multicentre, parallel, open-label, randomised controlled trial.

BACKGROUND: Based on evidence that mental health is more than an absence of mental disorders, there have been calls to find ways to promote flourishing at a population level, especially in young people, which requires effective and scalable interventions. Despite their potential for scalability, few mental wellbeing apps have been rigorously tested in high-powered trials, derived from models of healthy emotional functioning, or tailored to individual profiles. We aimed to test a personalised emotional competence self-help app versus a cognitive behavioural therapy (CBT) self-help app versus a self-monitoring app to promote mental wellbeing in healthy young people. METHODS: This international, multicentre, parallel, open-label, randomised controlled trial within a cohort multiple randomised trial (including a parallel trial of depression prevention) was done at four university trial sites in four countries (the UK, Germany, Spain, and Belgium). Participants were recruited from schools and universities and via social media from the four respective countries. Eligible participants were aged 16-22 years with well adjusted emotional competence profiles and no current or past diagnosis of major depression. Participants were randomised (1:1:1) to usual practice plus either the emotional competence app, the CBT app or the self-monitoring app, by an independent computerised system, minimised by country, age, and self-reported gender, and followed up for 12 months post-randomisation. The primary outcome was mental wellbeing (indexed by the Warwick-Edinburgh Mental Well Being Scale [WEMWBS]) at 3-month follow-up, analysed in participants who completed the 3-month follow-up assessment. Outcome assessors were masked to group allocation. The study is registered with ClinicalTrials.gov, NCT04148508, and is closed. FINDINGS: Between Oct 15, 2020, and Aug 3, 2021, 2532 participants were enrolled, and 847 were randomly assigned to the emotional competence app, 841 to the CBT app, and 844 to the self-monitoring app. Mean age was 19·2 years (SD 1·8). Of 2532 participants self-reporting gender, 1896 (74·9%) were female, 613 (24·2%) were male, 16 (0·6%) were neither, and seven (0·3%) were both. 425 participants in the emotional competence app group, 443 in the CT app group, and 447 in the self-monitoring app group completed the follow-up assessment at 3 months. There was no difference in mental wellbeing between the groups at 3 months (global p=0·47). The emotional competence app did not differ from the CBT app (mean difference in WEMWBS -0·21 [95% CI -1·08 to 0·66]) or the self-monitoring app (0·32 [-0·54 to 1·19]) and the CBT app did not differ from the self-monitoring app (0·53 [-0·33 to 1·39]). 14 of 1315 participants were admitted to or treated in hospital (or both) for mental health-related reasons, which were considered unrelated to the interventions (five participants in the emotional competence app group, eight in the CBT app group, and one in the self-monitoring app group). No deaths occurred. INTERPRETATION: The emotional competence app and the CBT app provided limited benefit in promoting mental wellbeing in healthy young people. This finding might reflect the low intensity of these interventions and the difficulty improving mental wellbeing via universal digital interventions implemented in low-risk populations.

Emotional competence self-help app versus cognitive behavioural self-help app versus self-monitoring app to prevent depression in young adults with elevated risk (ECoWeB PREVENT): an international, multicentre, parallel, open-label, randomised controlled trial.

BACKGROUND: Effective, scalable interventions are needed to prevent poor mental health in young people. Although mental health apps can provide scalable prevention, few have been rigorously tested in high-powered trials built on models of healthy emotional functioning or tailored to individual profiles. We aimed to test a personalised emotional competence app versus a cognitive behavioural therapy (CBT) self-help app versus a self-monitoring app to prevent an increase in depression symptoms in young people. METHODS: This multicentre, parallel, open-label, randomised controlled trial, within a cohort multiple randomised trial (including a parallel trial of wellbeing promotion) was done at four university trial sites in the UK, Germany, Spain, and Belgium. Participants were recruited from schools, universities, and social media from the four respective countries. Eligible participants were aged 16-22 years with increased vulnerability indexed by baseline emotional competence profile, without current or past diagnosis of major depression. Participants were randomly assigned (1:1:1) to usual practice plus either the personalised emotional competence self-help app, the generic CBT self-help app, or the self-monitoring app by an independent computerised system, minimised by country, age, and self-reported gender, and followed up for 12 months post-randomisation. Outcome assessors were masked to group allocation. The primary outcome was depression symptoms (according to Patient Health Questionnaire-9 [PHQ-9]) at 3-month follow-up, analysed in participants who completed the 3-month follow-up assessment. The study is registered with ClinicalTrials.gov, NCT04148508, and is closed. FINDINGS: Between Oct 15, 2020, and Aug 3, 2021, 1262 participants were enrolled, including 417 to the emotional competence app, 423 to the CBT app, and 422 to the self-monitoring app. Mean age was 18·8 years (SD 2·0). Of 1262 participants self-reporting gender, 984 (78·0%) were female, 253 (20·0%) were male, 15 (1·2%) were neither, and ten (0·8%) were both. 178 participants in the emotional competence app group, 191 in the CBT app group, and 199 in the self-monitoring app group completed the follow-up assessment at 3 months. At 3 months, depression symptoms were lower with the CBT app than the self-monitoring app (mean difference in PHQ-9 -1·18 [95% CI -2·01 to -0·34]; p=0·006), but depression symptoms did not differ between the emotional competence app and the CBT app (0·63 [-0·22 to 1·49]; p=0·15) or the self-monitoring app and emotional competence app (-0·54 [-1·39 to 0·31]; p=0·21). 31 of the 541 participants who completed any of the follow-up assessments received treatment in hospital or were admitted to hospital for mental health-related reasons considered unrelated to interventions (eight in the emotional competence app group, 15 in the CBT app group, and eight in the self-monitoring app group). No deaths occurred. INTERPRETATION: The CBT app delayed increases in depression symptoms in at-risk young people relative to the self-monitoring app, although this benefit faded by 12 months. Against hypotheses, the emotional competence app was not more effective at reducing depression symptoms than the self-monitoring app. CBT self-help apps might be valuable public mental health interventions for young people given their scalability, non-consumable nature, and affordability.

The Acceptability, Engagement, and Feasibility of Mental Health Apps for Marginalized and Underserved Young People: Systematic Review and Qualitative Study.

BACKGROUND: Smartphone apps may provide an opportunity to deliver mental health resources and interventions in a scalable and cost-effective manner. However, young people from marginalized and underserved groups face numerous and unique challenges to accessing, engaging with, and benefiting from these apps. OBJECTIVE: This study aims to better understand the acceptability (ie, perceived usefulness and satisfaction with an app) and feasibility (ie, the extent to which an app was successfully used) of mental health apps for underserved young people. A secondary aim was to establish whether adaptations can be made to increase the accessibility and inclusivity of apps for these groups. METHODS: We conducted 2 sequential studies, consisting of a systematic literature review of mental health apps for underserved populations followed by a qualitative study with underserved young male participants (n=20; age: mean 19). Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, an electronic search of 5 databases was conducted in 2021. The search yielded 18,687 results, of which 14 articles met the eligibility criteria. RESULTS: The included studies comprised a range of groups, including those affected by homelessness, having physical health conditions, living in low- and middle-income countries, and those with sexual and gender minority identities. Establishing and maintaining user engagement was a pervasive challenge across mental health apps and populations, and dropout was a reported problem among nearly all the included studies. Positive subjective reports of usability, satisfaction, and acceptability were insufficient to determine users' objective engagement. CONCLUSIONS: Despite the significant amount of funding directed to the development of mental health apps, juxtaposed with only limited empirical evidence to support their effectiveness, few apps have been deliberately developed or adapted to meet the heterogeneous needs of marginalized and underserved young people. Before mental health apps are scaled up, a greater understanding is needed of the types of services that more at-risk young people and those in limited-resource settings prefer (eg, standard vs digital) followed by more rigorous and consistent demonstrations of acceptability, effectiveness, and cost-effectiveness. Adopting an iterative participatory approach by involving young people in the development and evaluation process is an essential step in enhancing the adoption of any intervention, including apps, in "real-world" settings and will support future implementation and sustainability efforts to ensure that marginalized and underserved groups are reached.

Barriers and facilitators of implementation of evidence-based interventions in children and young people's mental health care - a systematic review.

BACKGROUND: Effective evidence-based practices (EBP) for children and young people's (CYP) mental health exist, however, there is low uptake in clinical practice and interventions do not always reach those in need. This review aimed to comprehensively identify and synthesise the barriers and facilitators to implementing EBP in CYP mental health care, mapped according to an implementation framework in order to make pragmatic recommendations for practitioners, commissioners and researchers. METHODS: Following the PRISMA guidelines, an electronic search of PsycINFO, MEDLINE, CINAHL and Embase in 2021 yielded 1830 results. In total, 107 abstracts were screened, 57 of which were included for full-text review and 26 were included for data extraction and analysis. RESULTS: We identified a number of organisational and clinician-level barriers which impede the implementation of evidence in 'real world' practice. Barriers included lack of access to funding; poor access to resources; clinician attitudes and flexibility of EBP. Facilitators included targeted funding and access to resources; supportive staff and leadership committed to innovation and skills in the EBP. CONCLUSIONS: Although the process of translating research into practice is challenging and the solutions are not straightforward, we have identified a set of practical recommendations for ways in which implementation practices can improve. Researchers, commissioners, funders and practitioners can work together to improve the implementation of EBP in CYP mental health settings by ensuring funding is available, prioritise implementation beyond the end of trials, upskill staff on integrating EBP into care, ensure EBPs are flexible and are co-produced with service users. REGISTRATION: This review was registered on PROSPERO international prospective register of systematic reviews (CRD42021252995).

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.

Determination of Markers of Successful Implementation of Mental Health Apps for Young People: Systematic Review.

BACKGROUND: Smartphone apps have the potential to address some of the current issues facing service provision for young people's mental health by improving the scalability of evidence-based mental health interventions. However, very few apps have been successfully implemented, and consensus on implementation measurement is lacking. OBJECTIVE: This review aims to determine the proportion of evidence-based mental health and well-being apps that have been successfully adopted and sustained in real-world settings. A secondary aim is to establish if key implementation determinants such as coproduction, acceptability, feasibility, appropriateness, and engagement contribute toward successful implementation and longevity. METHODS: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, an electronic search of 5 databases in 2021 yielded 18,660 results. After full-text screening, 34 articles met the full eligibility criteria, providing data on 29 smartphone apps studied with individuals aged 15 to 25 years. RESULTS: Of 34 studies, only 10 (29%) studies were identified that were evaluating the effectiveness of 8 existing, commercially available mental health apps, and the remaining 24 (71%) studies reported the development and evaluation of 21 newly developed apps, of which 43% (9/21) were available, commercially or otherwise (eg, in mental health services), at the time of enquiry. Most studies addressed some implementation components including adoption, acceptability, appropriateness, feasibility, and engagement. Factors including high cost, funding constraints, and lengthy research processes impeded implementation. CONCLUSIONS: Without addressing common implementation drivers, there is considerable redundancy in the translation of mobile mental health research findings into practice. Studies should embed implementation strategies from the outset of the planned research, build collaborations with partners already working in the field (academic and commercial) to capitalize on existing interventions and platforms, and modify and evaluate them for local contexts or target problems and populations.

A Transdiagnostic, Emotion Regulation App (Eda) for Children: Design, Development, and Lessons Learned.

BACKGROUND: Digital interventions, including mobile apps, represent a promising means of providing effective mental health support to children and young people. Despite the increased availability of mental health apps, there is a significant gap for this age group, especially for children (aged 10-12 years). Research investigating the effectiveness and development process of child mental health apps is limited, and the field faces persistent issues in relation to low user uptake and engagement, which is assumed to be a result of limited user involvement in the design process. OBJECTIVE: This study aims to present the development and design process of a new mental health app for children that targets their emotion regulation abilities. We describe the creation of a new interdisciplinary development framework to guide the design process and explain how each activity informed different app features. METHODS: The first 2 stages of the framework used a variety of methods, including weekly classroom observations over a 6-month period (20 in total); public engagement events with the target group (N=21); synthesis of the existing evidence as part of a meta-analysis; a series of co-design and participatory workshops with young users (N=33), clinicians (N=7), researchers (N=12), app developers (N=1), and designers (N=2); and finally, testing of the first high-tech prototype (N=15). RESULTS: For the interdisciplinary framework, we drew on methods derived from the Medical Research Council framework for complex interventions, the patient-clinician framework, and the Druin cooperative inquiry. The classroom observations, public engagement events, and synthesis of the existing evidence informed the first key pillars of the app and wireframes. Subsequently, a series of workshops shaped and reshaped the content and app features, including games, psychoeducational films, and practice modules. On the basis of the prototype testing sessions, we made further adjustments to improve the app. CONCLUSIONS: Although mobile apps could be highly suitable to support children's mental health on a wider scale, there is little guidance on how these interventions could be designed and developed. The involvement of young users across different design activities is very valuable. We hope that our interdisciplinary framework and description of the used methods will be helpful to others who are hoping to develop mental health apps for children and young people.

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.

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.

Understanding the illness representations of young people with anxiety and depression: A qualitative study.

BACKGROUND: Many young people with anxiety or depression drop out of treatment early, and/or leave treatment without showing measurably improved symptom levels. To enhance treatment engagement and effectiveness, it is critical to better understand how young people's perceptions of the symptoms, causes, consequences, treatability, and course of their anxiety and depression influence engagement. AIM: This study aimed to provide a qualitative account of illness perceptions among youth with anxiety and depression by applying the Common Sense Model of Self-Regulation (CSM), which was developed in physical health contexts. METHODS: Semi-structured interviews were conducted with 26 young people (aged 16-24, 73% female) with a history of anxiety and/or depression. Interviews were analysed using a combination of theory- and data-driven analysis techniques, consisting primarily of deductive thematic analysis. RESULTS: The five themes broadly mapped onto the dimensions of the CSM, suggesting parallels in how mental and physical health problems are perceived. Anxiety and depression were viewed as non-linear, relapsing and remitting, but lifelong conditions, with a fluctuating and complex path to recovery and coping. Youth described pervasive negative impacts on their lives, but also described some positive aspects. IMPLICATIONS: Better understanding of young people's illness beliefs has the potential to open a range of intervention possibilities by prioritizing young people's illness perceptions over the clinician's understanding and the supposed objective condition severity and trajectory. Although this study supported a common structure of illness beliefs, the content of these beliefs was idiosyncratic and specific to anxiety and depression, suggesting the need to develop a valid tool to measure illness perceptions in this group. PRACTITIONER POINTS: Our findings suggest that illness perceptions are complex, highly idiosyncratic, and specific to youth anxiety and depression. Given the complexity of these beliefs and the known association with important treatment- and health-related outcomes, it is important that clinical formulation incorporates young people's illness belief models, including their perceptions of symptoms, cause, timeline to recovery, consequences, and personal and treatment control. To increase help-seeking, treatment engagement and adaptive coping strategies, therapy should work to a shared understanding of illness beliefs. Increasing congruence between the belief models of young people, families, and clinicians may serve to improve treatment benefits and address the unmet mental health needs of young people.

Systematic Review and Meta-analysis: Outcomes of Routine Specialist Mental Health Care for Young People With Depression and/or Anxiety.

OBJECTIVE: Depression and anxiety are the most prevalent mental health problems in youth, yet almost nothing is known about what outcomes are to be expected at the individual level following routine treatment. This paper sets out to address this gap by undertaking a systematic review of outcomes following treatment as usual (TAU) with a particular focus on individual-level outcomes. METHOD: MEDLINE, Embase and PsycInfo were searched for articles published between 1980 and January 2019 that assessed TAU outcomes for youth depression and anxiety accessing specialist mental health care. Meta-analysis considered change at both group-level pre-post effect size (ES) and individual-level recovery, reliable change, and reliable recovery. Temporal analysis considered stability of primary and secondary outcomes over time. Subgroup analysis considered the moderating effect of informant; presenting problem; study design; study year; mean age of youth; use of medication; intervention dosage and type of treatment offered on outcomes. A protocol was preregistered on PROSPERO (CRD42017063914). RESULTS: Initial screening of 6,350 publications resulted in 38 that met the inclusion criteria, and that were subsequently included in meta-analyses. This resulted in a final full pooled sample of 11,739 young people (61% of whom were female, mean age 13.8 years). The pre-post ES (Hedges' g) at first/final outcome (13/26 weeks) was -0.74/-0.87. The individual-level change on measures of self-report was 38% reliable improvement, 44% no reliable change, and 6% reliable deterioration. Outcomes varied according to moderators, informant, problem type and dosage. CONCLUSION: Poor data quantity and quality are limitations, but this is the first study that indicates likely rates of reliable improvement for those accessing TAU. We propose the need for improved reporting of both individual-level metrics and details of TAU to enable greater understanding of likely current outcomes from routine care for youths with depression and anxiety in order to allow the potential for further improvement of impact.

Review: What Outcomes Count? A Review of Outcomes Measured for Adolescent Depression Between 2007 and 2017.

OBJECTIVE: Measurement of treatment outcomes in childhood depression has traditionally focused on assessing symptoms from the clinician's perspective, without exploring other outcome domains or considering young people's perspectives. This systematic review explored the extent to which multidimensional and multi-informant outcome measurements have been used in clinical research for adolescent depression in the past decade and how patterns have evolved over time. METHOD: Embase, Medline, and PsycINFO were searched, and studies that were published from 2007 through 2017 and assessed the effectiveness of treatments or service provision for adolescent depression were included. Of 7,483 studies screened, 95 met the inclusion criteria and were included for data extraction and analysis. RESULTS: Ten outcomes domains were identified, 2 of which were assessed on average using 4 outcome measures. Most studies (94%) measured symptoms, followed by functioning (52%). Other domains such as personal growth, relationships, quality of life, and service satisfaction were each considered by less than 1 in 10 studies. Youth self-report was considered by 54% but tended to focus on secondary outcomes. Multidimensional and multi-informant measurements were more frequent in studies published since 2015. CONCLUSION: Recent clinical research continues to prioritize symptoms measurement based on clinician report and has not yet fully embraced multidimensional and multi-informant approaches. In the context of significant policy shifts toward patient-centered and evidence-based care, measuring what matters most to patients has become a priority, but this is not yet widely reflected in clinical research.

Adolescent and parent factors related to fatigue in paediatric multiple sclerosis and chronic fatigue syndrome: A comparative study.

BACKGROUND: Fatigue is a disabling, poorly understood symptom in children and adolescents with multiple sclerosis (caMS), for which effective treatments are lacking. In paediatric Chronic Fatigue Syndrome (CFS), effective psychological interventions have been developed based on psychosocial factors associated with fatigue. This study aimed to identify potentially modifiable factors of fatigue in caMS by comparing caMS, adolescents with CFS, healthy adolescents and their parents on measures of fatigue, psychosocial factors, and neurocognitive functioning. METHODS: 175 participants including 30 caMS (15 fatigued, 15 non-fatigued), 30 adolescents with CFS, 30 healthy controls, and their parents were compared on measures of self- and parent-reported fatigue, adolescent and parent cognitive behavioural responses to symptoms, sleep, psychological difficulties, parental distress and objectively measured neurocognitive functioning. RESULTS: Fatigue severity, functional impairment and cognitive behavioural responses to symptoms were equivalent in fatigued caMS and adolescents with CFS, and were significantly higher than in healthy controls and non-fatigued caMS. Neurocognitive functioning was impaired in both caMS groups, but was normal in adolescents with CFS and healthy controls. No between-group differences were identified in adolescent sleep behaviour or psychological difficulties. Parents of all illness groups had more unhelpful cognitions than parents of healthy controls. Psychological distress was elevated in parents of both fatigued groups. CONCLUSIONS: Fifty percent of caMS reported clinically significant fatigue. Similarities between adolescent and parent cognitive behavioural factors in fatigued caMS and adolescents with CFS suggest important potential targets for intervention. Both fatigued and non-fatigued caMS had cognitive difficulties, suggesting that fatigue may need targeted intervention.

Evaluation of reliable improvement rates in depression and anxiety at the end of treatment in adolescents.

BACKGROUND: Literature has focused on effect sizes rather than individual-level improvement rates to determine how effectively services address burgeoning numbers of adolescents with anxiety and depression.AimsTo consider how many adolescents report reliable improvement in anxiety, depression and comorbid depression and anxiety by end of treatment. METHOD: The primary outcome was reliable improvement (i.e. change greater than likely the result of measurement error) in self-reported anxiety and depression for N = 4464 adolescents (mean age 14.5 years, s.d. = 1.9; 75% female; 61% White) seen in specialist mental health services in England. RESULTS: In total, 53% of those with anxiety, 44% with depression, and 35% with comorbid depression and anxiety showed reliable improvement. CONCLUSIONS: Improvement rates were higher than previously reported, but lower than generally used in advice to the public. There may be a need to set more realistic expectations, including with young people who seek help.Declaration of interestAll authors were involved in the programme of service transformation that this report draws on.
