Comparing Strategies for Providing Child and Youth Mental Health Care Services in Canada, the United States, and The Netherlands

Beyond the mean: Distributional differences in earnings and mental health in young adulthood by childhood health histories

Research on the long-term effects of health in early life has predominantly relied on parametric methods to assess differences between groups of children. However, this approach leaves a wealth of distributional information untapped. The objective of this study was to assess distributional differences in earnings and mental health in young adulthood between individuals who suffered a chronic illness in childhood compared to those who did not using the non-parametric relative distributions framework. Using data from the Panel Study of Income Dynamics, we find that young adults who suffered a chronic illness in childhood fare worse in terms of earnings and mental health scores in adulthood, particularly for individuals reporting a childhood mental health/developmental disorder. Covariate decompositions suggest that chronic conditions in childhood may indirectly affect later outcomes through educational attainment: had the two groups had similar levels of educational attainment, the proportion of individuals with a report of a chronic condition in childhood in the lower decile of the relative earnings distribution would have been reduced by about 20 percentage points. Findings may inform policy aimed at mitigating longer run effects of health conditions in childhood and may generate hypotheses to be explored in parametric analyses.

The "Long-arm" of chronic conditions in childhood: Evidence from Canada using linked survey-administrative data

The objective of this study was to investigate the relationship between health conditions in childhood (ages 4-11), and health and socioeconomic outcomes in adulthood (ages 21-33). This study takes advantage of a new linkage between the National Longitudinal Survey of Children and Youth (NLSCY) and administrative tax data from the T1 Family File (T1FF) from Statistics Canada. The NLSCY includes rich longitudinal information on child development, while the T1FF includes administrative tax information on each child in adulthood (e.g., income, social assistance). The primary measures of child health relate to the diagnosis of a chronic condition, affecting the child's physical or mental/developmental health. The results suggest that mental/developmental health conditions in childhood more negatively influence adult health and socioeconomic conditions, compared to physical health conditions. Interaction models reveal modest heterogenous effects; for example, there is some evidence of a cushioning effect from higher household income in childhood, as well as an exacerbating negative effect from lower birth weight for mental/developmental health conditions. Using a covariate decomposition approach to explore underlying pathways, the results reveal that associations between health in early life and outcomes in adulthood are partially explained by differences in cognitive skills (i.e., mathematics test scores) in adolescence (ages 16-17). Results may encourage policy investments to mitigate the occurrence of health conditions in childhood and to ensure timely access to educational supports and health services for children with chronic conditions.

Access to mental health and addiction services for youth and their families in Ontario: perspectives of parents, youth, and service providers

BACKGROUND

Canadian youth (aged 16-24) have the highest rates of mental health and addiction concerns across all age groups and the most unmet health care needs. There are many structural barriers that contribute to the unmet mental health care needs of youth including lack of available and appropriate services, high costs, long wait times, fragmented and siloed services, lack of smooth transition between child and adult services, stigma, racism, and discrimination, as well as lack of culturally appropriate treatments. Levesque et al. (2013) developed a framework to better understand health care access and this framework conceptualizes accessibility across five dimensions: (1) approachability, (2) availability, (3) affordability, (4) appropriateness, and (5) acceptability. The purpose of this study was to explore access to addiction and mental health services for youth in Ontario, Canada from the perspectives of youth, parents, and service providers.

METHODS

This qualitative study was a university-community partnership exploring the experiences of youth with mental health concerns and their families from the perspectives of youth, caregivers, and service providers. We conducted semi-structured interviews and used thematic analysis to analyze data.

RESULTS

The study involved 25 participants (n = 11 parents, n = 4 youth, n = 10 service providers). We identified six themes related to structural barriers impacting access to youth mental health and services: (1) "The biggest barrier in accessing mental health support is where to look," (2) "There's always going to be a waitlist," (3) "I have to have money to be healthy," (4) "They weren't really listening to my issues," (5) "Having more of a welcoming and inclusive system," and (6) "Health laws aren't doing what they need to do."

CONCLUSION

Our study identified five structural barriers that map onto the Levesque et al. healthcare access conceptual framework and a sixth structural barrier that is not adequately captured by this model which focuses on policies, procedures, and laws. The findings have implications for policies and service provisions, and underline the urgent need for a mental health strategy that will increase access to care, improve mental health in youth, decrease burden on parents, and reduce inequities in mental health policies and services.

Digital interventions for substance use disorders in young people: rapid review

BACKGROUND

Young people are disproportionately more likely than other age groups to use substances. The rise in substance use and related harms, including overdose, during the Covid-19 pandemic has created a critical need for more innovative and accessible substance use interventions. Digital interventions have shown effectiveness and can provide more engaging, less stigmatizing, and accessible interventions that meet the needs of young people. This review provides an overview of recent literature on the nature of recently published digital interventions for young people in terms of technologies used, substances targeted, intended outcomes and theoretical or therapeutic models employed.

METHODS

Rapid review methodology was used to identify and assess the literature on digital interventions for young people. An initial keyword search was conducted using MEDLINE the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database (HTA) and PROSPERO for the years 2015-2020, and later updated to December 2021. Following a title/abstract and full-text screening of articles, and consensus decision on study inclusion, the data extraction process proceeded using an extraction grid developed for the study. Data synthesis relied on an adapted conceptual framework by Stockings, et al. that involved a three-level treatment spectrum for youth substance use (prevention, early intervention, and treatment) for any type of substance.

RESULTS

In total, the review identified 43 articles describing 39 different digital interventions. Most were early interventions (n = 28), followed by prevention interventions (n = 6) and treatment interventions (n = 5). The identified digital technologies included web-based (n = 14), game-based (n = 10), mobile-based (n = 7), and computer-based (n = 5) technologies, and virtual reality (n = 3). Most interventions targeted alcohol use (n = 20) followed by tobacco/nicotine (n = 5), cannabis (n = 2), opioids (n = 2), ketamine (1) and multiple, or any substances (n = 9). Most interventions used a personalized or normative feedback approach and aimed to effect behaviour change as the intended outcome. Interestingly, a harm reduction approach guided only one of the 39 interventions.

CONCLUSIONS

While web-based interventions represented the most common type of technology, more recently developed immersive and interactive technologies such as virtual reality and game-based interventions call for further exploration. Digital interventions focused mainly on alcohol use, reflecting less concern for tobacco, cannabis, co-occurring substance use, and illicit drug use. Specifically, the recent exacerbation in the opioid crisis throughout North American underlines the urgent need for more prevention-oriented digital interventions for opioid use. The uptake of digital interventions among youth also depends on the incorporation of harm reduction approaches.

Determinants of e-Mental Health Use During COVID-19: Cross-sectional Canadian Study

Background

Access to mental health treatment across Canada remains a challenge, with many reporting unmet care needs. National and provincial e-Mental health (eMH) programs have been developed over the past decade across Canada, with many more emerging during COVID-19 in an attempt to reduce barriers related to geography, isolation, transportation, physical disability, and availability.

Objective

The aim of this study was to identify factors associated with the utilization of eMH services across Canada during the COVID-19 pandemic using Andersen and Newman’s framework of health service utilization.

Methods

This study used data gathered from the 2021 Canadian Digital Health Survey, a cross-sectional, web-based survey of 12,052 Canadians aged 16 years and older with internet access. Bivariate associations between the use of eMH services and health service utilization factors (predisposing, enabling, illness level) of survey respondents were assessed using χ2 tests for categorical variables and t tests for the continuous variable. Logistic regression was used to predict the probability of using eMH services given the respondents’ predisposing, enabling, and illness-level factors while adjusting for respondents’ age and gender.

Results

The proportion of eMH service users among survey respondents was small (883/12,052, 7.33%). Results from the logistic regression suggest that users of eMH services were likely to be those with regular family physician access (odds ratio [OR] 1.57, P=.02), living in nonrural communities (OR 1.08, P<.001), having undergraduate (OR 1.40, P=.001) or postgraduate (OR 1.48, P=.003) education, and being eHealth literate (OR 1.05, P<.001). Those with lower eMH usage were less likely to speak English at home (OR 0.06, P<.001).

Conclusions

Our study provides empirical evidence on the impact of individual health utilization factors on the use of eMH among Canadians during the COVID-19 pandemic. Given the opportunities and promise of eMH services in increasing access to care, future digital interventions should both tailor themselves toward users of these services and consider awareness campaigns to reach nonusers. Future research should also focus on understanding the reasons behind the use and nonuse of eMH services.

Comparison of antipsychotic drug use among Dutch Youth before and after implementation of the Youth Act (2010-2019)

OBJECTIVE

The Dutch law on youth care (the Youth Act) was implemented from 2015 onwards. One of the government's aims by implementing this new policy was de-medicalization of youths by separating youth mental healthcare from the rest of the healthcare system. A previous study conducted by our research group showed that prevalence rates of antipsychotic drug prescriptions stabilized among Dutch youth in the period 2005-2015, just before the introduction of the Youth Act. In our study, we aimed to describe antipsychotic drug use among Dutch children aged 0-19 years old before and after implementation of the Youth Act (2010-2019).

METHODS

We analyzed prescription data of 7405 youths aged 0-19 years using antipsychotic drugs between 2010 and 2019, derived from a large Dutch community pharmacy-based prescription database (IADB.nl).

RESULTS

Prevalence rates of antipsychotic drug use per thousand youths decreased significantly in youths aged 7-12 years old in 2019 compared to 2015 (7.9 vs 9.0 p < 0.05). By contrast, prevalence rates increased in adolescent females in 2019 compared to 2015 (11.8 vs 9.5 p < 0.05). Incidence rates increased significantly in adolescent youths in 2019 compared to 2015 (3.9 vs 3.0 p < 0.05), specifically among adolescent girls (4.2 per thousand in 2019 compared to 3.0 per thousand in 2015). Dosages in milligram declined for the most commonly prescribed antipsychotic drugs during the study period. The mean duration of antipsychotic drug use in the study period was 5.7 (95% CI 5.2-6.2) months.

CONCLUSION

Despite the aim of the Youth Act to achieve de-medicalization of youths, no clear reduction was observed in prevalence rates of antipsychotic drugs or treatment duration in all subgroups. Prevalence rates even increased in adolescent females.

Sociodemographic and clinical characteristics in child and youth mental health; comparison of routine outcome measurements of an Australian and Dutch outpatient cohort

AIMS

Although of great value to understand the treatment results for mental health problems obtained in clinical practice, studies using naturalistic data from children and adolescents seeking clinical care because of complex mental health problems are limited. Cross-national comparison of naturalistic outcomes in this population is seldomly done. Although careful consideration is needed, such comparisons are likely to contribute to an open dialogue about cross-national differences and may stimulate service improvement. The aim of this observational study is to investigate clinical characteristics and outcomes in naturalistic cohorts of specialized child and adolescent mental health outpatient care in two different countries.

METHODS

Routinely collected data from 2013 to 2018 of 2715 outpatients in the Greater Area of Brisbane, Australia (CYMHS) and 1158 outpatients in Leiden, the Netherlands (LUMC-Curium) were analysed. Demographics, clinical characteristics and severity of problems at start and end of treatment were described, using Children's Global Assessment Scale (CGAS), Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) and the parental Strength and Difficulties Questionnaire (SDQ-P).

RESULTS

Routine outcome measures (CGAS, HoNOSCA, SDQ-P) showed moderate to severe mental health problems at start of treatment, which improved significantly over time in both cohorts. Effect sizes ranged between 0.73-0.90 (CYMHS) and 0.57-0.76 (LUMC-Curium). While internalizing problems (mood disorder, anxiety disorder and stress-related disorder) were more prevalent at CYMHS, externalizing developmental problems (ADHD, autism) prevailed at LUMC-Curium. Comorbidity (>1 diagnosis on ICD10/DSM-IV) was relatively similar: 45% at CYMHS and 39 % at LUMC-Curium. In both countries, improvement of functioning was lowest for conduct disorder and highest for somatoform/conversion disorders and obsessive-compulsive disorders (OCD). Overall, 20-40% showed clinically significant improvement (shift from clinical-range at start to a non-clinical-range at the end of treatment), but nearly half of patients still experienced significant symptoms at discharge.

CONCLUSIONS

This large-scale outcome study showed both cohorts from Australia and the Netherlands improve during the course of treatment on clinician- and parent-reported measures. Although samples were situated within different contexts and differed in patient profiles, they showed similar trends in improvement per diagnostic group. While 20-40% showed clinically significant change, many patients experienced residual symptoms reflecting increased risk for negative outcome into adulthood. We emphasize cross-national comparison of naturalistic outcomes faces challenges, although it can similarly reveal trends in treatment outcome providing direction for future research: what factors determine discharge from specialized services; and how to improve current treatments in this severely affected population.

Youths' Perceived Impact of Invalidation and Validation on Their Mental Health Treatment Journeys

Youths' experiences in seeking and accessing help for mental health problems can have pervasive and lasting effects on personal and interpersonal functioning. In particular, youth who experience validating experiences presumably persevere in seeking help and generally have positive treatment outcomes, whereas youth who experience invalidation are also likely to experience, at least in the short term, ruptures in therapeutic relationships, shame, and reluctance to seek services. The goal of the current study was to expand on previous research assessing youths' interactions with mental health providers, allied professionals, family members, and peers, with a focus on subjective experiences of validation and invalidation. The current study investigated both validating and invalidating experiences in seeking, accessing, and maintaining professional services among 31 Canadian youth (n = 20 girls, n = 11 boys; 12 to 21 years old [M = 16.97, SD = 2.01]) who were diagnosed or self-identified with at least one of five conditions: depression (n = 26), anxiety (n = 22), eating disorders (n = 9), autism spectrum disorder (n = 2), or conduct disorder or oppositional defiant disorder (n = 2). Youth were recruited using convenience (e.g., posted advertisements in mental health clinics) and snowball sampling methods. Journey mapping methodology (i.e., participants created visual representations of milestones of their mental health journeys) was employed accompanied by semi-structured interviews to prompt youth to expand on their experiences (e.g., "Could you describe what was happening in your life when you first felt you would need support for your mental health?"). Four themes emerged using inductive thematic analysis, marked by the presence (validation) or lack (invalidation) of: feeling heard, feeling seen, feeling understood, and receiving helpful actions. Participants also reported key consequences of validation and invalidation. Findings broaden a conceptualization of validation across supportive relationships and an understanding of factors that enhance or impede the formation or maintenance of therapeutic relationships with youth. Clinical implications and limitations are discussed.

Following the Epidemic Waves: Child and Youth Mental Health Assessments in Ontario Through Multiple Pandemic Waves

Emerging studies across the globe are reporting the impact of COVID-19 and its related virus containment measures, such as school closures and social distancing, on the mental health presentations and service utilization of children and youth during the early stages of lockdowns in their respective countries. However, there remains a need for studies which examine the impact of COVID-19 on children and youth's mental health needs and service utilization across multiple waves of the pandemic. The present study used data from 35,162 interRAI Child and Youth Mental Health (ChYMH) assessments across 53 participating mental health agencies in Ontario, Canada, to assess the mental health presentations and referral trends of children and youth across the first two waves of the COVID-19 pandemic in the province. Wave 1 consisted of data from March to June 2020, with Wave 2 consisting of data from September 2020 to January 2021. Data from each wave were compared to each other and to the equivalent period one year prior. While assessment volumes declined during both pandemic waves, during the second wave, child and youth assessments in low-income neighborhoods declined more than those within high-income neighborhoods. There were changes in family stressors noted in both waves. Notably, the proportion of children exposed to domestic violence and recent parental stressors increased in both waves of the pandemic, whereas there were decreases noted in the proportion of parents expressing feelings of distress, anger, or depression and reporting recent family involvement with child protection services. When comparing the two waves, while depressive symptoms and recent self-injurious attempts were more prevalent in the second wave of the pandemic when compared to the first, a decrease was noted in the prevalence of disruptive/aggressive behaviors and risk of injury to others from Wave 1 to Wave 2. These findings highlight the multifaceted impact of multiple pandemic waves on children and youth's mental health needs and underscore the need for future research into factors impacting children and youth's access to mental health agencies during this time.

Using epidemiological evidence to forecast population need for early treatment programmes in mental health: a generalisable Bayesian prediction methodology applied to and validated for first-episode psychosis in England

BACKGROUND

Mental health policy makers require evidence-based information to optimise effective care provision based on local need, but tools are unavailable.

AIMS

To develop and validate a population-level prediction model for need for early intervention in psychosis (EIP) care for first-episode psychosis (FEP) in England up to 2025, based on epidemiological evidence and demographic projections.

METHOD

We used Bayesian Poisson regression to model small-area-level variation in FEP incidence for people aged 16-64 years. We compared six candidate models, validated against observed National Health Service FEP data in 2017. Our best-fitting model predicted annual incidence case-loads for EIP services in England up to 2025, for probable FEP, treatment in EIP services, initial assessment by EIP services and referral to EIP services for 'suspected psychosis'. Forecasts were stratified by gender, age and ethnicity, at national and Clinical Commissioning Group levels.

RESULTS

A model with age, gender, ethnicity, small-area-level deprivation, social fragmentation and regional cannabis use provided best fit to observed new FEP cases at national and Clinical Commissioning Group levels in 2017 (predicted 8112, 95% CI 7623-8597; observed 8038, difference of 74 [0.92%]). By 2025, the model forecasted 11 067 new treated cases per annum (95% CI 10383-11740). For every 10 new treated cases, 21 and 23 people would be assessed by and referred to EIP services for suspected psychosis, respectively.

CONCLUSIONS

Our evidence-based methodology provides an accurate, validated tool to inform clinical provision of EIP services about future population need for care, based on local variation of major social determinants of psychosis.

The Impact of Demographic, Clinical, and Institutional Factors on Psychiatric Inpatient Length-of-Stay

The average length of inpatient stay (LOS) for psychiatric care has declined substantially across Canada and the United States during the past two decades. Although LOS is based presumably on patient, hospital, and community factors, there is little understanding of how such factors are linked with LOS. The purpose of this study was to explore potential individual and systemic factors associated with LOS in a large-scale, longitudinal dataset. Study participants consisted of individuals 11 years of age and older admitted for psychiatric conditions to a New Brunswick hospital between April 1, 2003 and March 31, 2014 (N = 51,865). The study used a retrospective cohort design examining data from the New Brunswick Discharge Abstract Database, administrative data comprised of all inpatient admissions across provincial hospitals. Hierarchical regression analysis was used to estimate the association of individual, facility, and system-level factors with psychiatric LOS. Results indicated that hospital-level factors and individual-level characteristics (i.e., discharge disposition, aftercare referral, socioeconomic status (SES)) account for significant variability in LOS. Consistent with extant literature, our results found that hospital, clinical, and individual factors together are associated with LOS. Furthermore, our results highlight demographic factors surrounding living situation and available financial supports, as well as the match or mismatch between preferred language and language in which services are offered.

Longitudinal examination of youth readmission to mental health inpatient units

OBJECTIVE

Significant barriers exist for youth in obtaining mental health services. These barriers are exacerbated by growing demand, attributed partially to children and adolescents who have repeat hospital admissions. The purpose of this study was to identify demographic, socioeconomic and clinical predictors of readmission to inpatient psychiatric services in New Brunswick, Canada.

METHOD

Key demographic, support and clinical predictors of readmission were identified. The New Brunswick Discharge Abstract Database (DAD) was used to compile a cohort of all children and adolescents ages 3-19 years with psychiatric hospital admissions between 1 April 2003 and 31 March 2014 (N = 3825). Primary analyses consisted of Kaplan-Meier survival methods with log-rank tests to assess time-to-readmission variability, and Cox regression to identify significant predictors of readmission.

RESULTS

In total, 27.8% of admitted children and adolescents experienced at least one readmission within the 10-year period, with 57.3% readmitted to hospital within 90 days following discharge. Bivariate results indicated that male, upper-middle socioeconomic status (SES) youths aged 11-15 years from nonrural communities were most likely to be readmitted. Notable predictors of increased readmission likelihood were older age, being male, higher SES, referral to care by medical practitioner, discharge to another health facility, psychosis, and previous psychiatric admission.

CONCLUSION

A significant portion of the variance in readmission was accounted for by youth demographic characteristics (i.e. age, SES, geographic location) and various support structures, including referrals to inpatient care and aftercare support services.

KEY PRACTITIONER MESSAGE

Readmission to inpatient psychiatric care among youth is affected by a number of multifaceted risk factors across individual, environmental and clinical domains. This study used provincial population-scale longitudinal administrative data to demonstrate the influence of various individual and demographic factors on likelihood of readmission, which is notably absent from the majority of studies that make use of smaller, short-term data samples. Ensuring that multiple factors outside of the clinical context are considered when examining readmission among youth may contribute to a more thorough understanding of youth hospitalization patterns.

Ontario's response to COVID-19 shows that mental health providers must be integrated into provincial public health insurance systems

The fear, grief, social isolation, and financial and occupational losses from COVID-19 have created a mental health crisis. Ontario’s response highlights the shortcomings of its physician-only public healthcare system that limits public access to appropriate and sustainable mental healthcare. Specifically, Ontario’s attempt to rapidly expand mental healthcare access in response to COVID-19 includes new Ontario Health Insurance Program (OHIP) billing codes that enable physicians to provide telephonic trauma counselling and patient self-serve online tools while psychologist and other registered mental health provider services have been largely left out of the provincial response. Why? Non-physician mental health providers operate outside of the provincial healthcare infrastructure, including the provincial payer (i.e., OHIP) that facilitated the provincial physician response. A physician-centric mental healthcare system limits public access to quality, sustainable, evidence-based mental health services because most physicians do not have the capacity, training, or desire to provide mental health services. To improve public access to needed mental health services, provinces should integrate psychologists and other registered mental health providers directly into their public health insurance systems. Integrated providers can be strategically and sustainably mobilized to respond to COVID-19 and future mental health crises.

The Use of Text Messaging to Improve Clinical Engagement for Individuals With Psychosis: Systematic Review

BACKGROUND

Individuals experiencing psychosis are at a disproportionate risk for premature disengagement from clinical treatment. Barriers to clinical engagement typically result from funding constraints causing limited access to and flexibility in services. Digital strategies, such as SMS text messaging, offer a low-cost alternative to potentially improve engagement. However, little is known about the efficacy of SMS text messaging in psychosis.

OBJECTIVE

This review aimed to address this gap, providing insights into the relationship between SMS text messaging and clinical engagement in the treatment of psychosis.

METHODS

Studies examining SMS text messaging as an engagement strategy in the treatment of psychosis were reviewed. Included studies were published from the year 2000 onward in the English language, with no methodological restrictions, and were identified using 3 core databases and gray literature sources.

RESULTS

Of the 233 studies extracted, 15 were eligible for inclusion. Most studies demonstrated the positive effects of SMS text messaging on dimensions of engagement such as medication adherence, clinic attendance, and therapeutic alliance. Studies examining the feasibility of SMS text messaging interventions found that they are safe, easy to use, and positively received.

CONCLUSIONS

Overall, SMS text messaging is a low-cost, practical method of improving engagement in the treatment of psychosis, although efficacy may vary by symptomology and personal characteristics. Cost-effectiveness and safety considerations were not adequately examined in the studies included. Future studies should consider personalizing SMS text messaging interventions and include cost and safety analyses to appraise readiness for implementation.

Integrated Mental Health Services for the Developmental Period (0 to 25 Years): A Critical Review of the Evidence

Background: The developmental period from 0 to 25 years is a vulnerable time during which children and young people experience many psychosocial and neurobiological changes and an increased incidence of mental illness. New clinical services for children and young people aged 0 to 25 years may represent a radical transformation of mental healthcare. Method: Critical, non-systematic review of the PubMed literature up to 3rd January 2019. Results: Rationale: the youngest age group has an increased risk of developing mental disorders and 75% of mental disorders begin by the age of 24 and prodromal features may start even earlier. Most of the risk factors for mental disorders exert their role before the age of 25, profound maturational brain changes occur from mid-childhood through puberty to the mid-20s, and mental disorders that persist in adulthood have poor long-term outcomes. The optimal window of opportunity to improve the outcomes of mental disorders is the prevention or early treatment in individuals aged 0 to 25 within a clinical staging model framework. Unmet needs: children and young people face barriers to primary and secondary care access, delays in receiving appropriate treatments, poor engagement, cracks between child and adult mental health services, poor involvement in the design of mental health services, and lack of evidence-based treatments. Evidence: the most established paradigm for reforming youth mental services focuses on people aged 12-25 who experienced early stages of psychosis. Future advancements may include early stages of depression and bipolar disorders. Broader youth mental health services have been implemented worldwide, but no single example constitutes best practice. These services seem to improve access, symptomatic and functional outcomes, and satisfaction of children and young people aged 12-25. However, there are no robust controlled trials demonstrating their impact. Very limited evidence is available for integrated mental health services that focus on people aged 0-12. Conclusions: Children and young people aged 12-25 need youth-friendly mental health services that are sensitive to their unique stage of clinical, neurobiological, and psychosocial development. Early intervention for psychosis services may represent the starting platform to refine the next generation of integrated youth mental health services.
