This chapter explores the transformative potential of early intervention in schizophrenia, emphasizing its role in improving clinical, functional, and social outcomes. Through the poignant case of “Roger,” a man whose life was marked by untreated psychosis, homelessness, and missed opportunities for care, the chapter illustrates the consequences of delayed treatment and fragmented systems. It reviews epidemiological data, the importance of reducing the duration of untreated psychosis (DUP), and the neurobiological rationale for early-phase treatment. Models such as Coordinated Specialty Care (CSC), EPPIC, and Assertive Community Treatment (ACT) are discussed as effective frameworks for delivering comprehensive, multidisciplinary care. The chapter also addresses barriers to early intervention—including stigma, misdiagnosis, access limitations, and systemic inequities—and advocates for integrated, culturally responsive, and person-centered approaches. Ultimately, it calls for a shift in healthcare systems to prioritize early identification and treatment as a moral and clinical imperative.
Restrictive interventions are used in the treatment of some people with severe mental disorders such as psychosis – including psychiatric intensive care unit (PICU) admission, seclusion and restraint. Early Intervention in Psychosis (EIP) service input may improve outcomes in psychosis, but it is unclear whether specific components of EIP care reduce the need for restrictive practice.
Aims
To examine associations between EIP care components, demographic characteristics and restrictive interventions.
Method
We conducted a retrospective cohort study of 14 874 people who used EIP services in England, using linked data from the National Clinical Audit of Psychosis and the Mental Health Services Data Set. We examined associations between EIP components and time to PICU admission (primary outcome) alongside seclusion/physical restraint/injected chemical restraint/requests for police assistance (secondary outcomes), using multilevel Cox regression, adjusting for demographic factors and clustering by service.
Results
Higher hazards of restrictive interventions were observed among men, younger people and several minority ethnic groups. Individuals eligible for clozapine who were not offered it (hazard ratio 1.51, 95% CI 1.20–1.91) or refused it (hazard ratio 1.46, 95% CI 1.02–2.10) had higher hazards of PICU admission than those not eligible, whereas those who were eligible for clozapine and received it did not. There was weaker evidence of similar effects on hazards of physical restraint and seclusion. Receipt of CBT for psychosis was associated with reduced hazards of PICU admission (hazard ratio 0.80, 95% CI 0.67–0.95) and physical restraint (hazard ratio 0.68, 95% CI 0.47–0.98). Substance use was associated with increased hazards of PICU admission and requests for police assistance, although substance use interventions appeared to partially mitigate this.
Conclusions
Marked demographic disparities exist in the use of restrictive practice. Specific EIP care components may be associated with reductions. Strengthening evidence-based EIP provision and addressing structural inequalities may support progress towards less coercive and more equitable care.
Research suggests that well-developed parent engagement programs can boost early learning and reduce socioeconomic disparities in subsequent school adjustment. Yet few follow-up studies exist. To address this gap, we followed participants in the Research-based, Developmentally Informed-Parent [REDI-P] intervention study for 8 years to evaluate adolescent outcomes. Participants included 200 4-year-old children (55% White, 26% Black, 19% Latinx; 56% male, 44% female; Mage at study entry = 4.45 years) attending Head Start. Families were randomly assigned to REDI-P home learning materials and coaching or an attention control group. Multi-method measures tracked child literacy skills, learning behaviors, social competence, and conduct problems through grade 7. GLM analyses revealed significant preschool intervention effects on grade 7 working memory, β = 0.35, 95% CI 0.08, 0.62, p = .01; perceived social competence, β = 0.30, 95% CI 0.02, .58, p = .04; deviant peer affiliation, β = −0.33, 95% CI −0.60, −0.06, p = .02; and teacher-rated conduct problems, β = −0.30, 95% CI −0.58, −0.01, p = .04. Serial path models identified developmental progressions linking initial intervention effects to adolescent outcomes. Results highlight the long-term value of empowering parents to support the early social-emotional and pre-academic learning of their preschool children.
Infants with single ventricle CHD commonly experience gross motor delays due to physiological and environmental factors, including increased risk for white matter injury, reduced aerobic capacity, restrictive post-operative protocols, and limited movement opportunities. These delays persist in adolescence, affecting physical and social development. This study examines a quality improvement initiative within the National Pediatric Cardiology Quality Improvement Collaborative to enhance gross motor development.
Methods:
Fifteen centres participated. Gross motor skills were assessed using the Ages and Stages Questionnaires, Third Edition, at 6 and 12 months. A key driver diagram, Plan-Do-Study-Act cycles, baseline data, and ongoing process measures were collected. Interventions were implemented, including education, therapy support, and mobilisation protocols. Control charts were used to evaluate the data.
Results:
Scores from the Ages and Stages Questionnaires indicated delays in gross motor skills at baseline, with improvement over time. Participating centres showed a centerline shift from 41% to 89% of infants achieving on-target or improved motor scores, compared with 54% to 68% of infants at non-participating centres. Establishment of customised infant developmental plans increased from 62% to 74% for participating centres and from 53% to 61% for non-participating centres. Interventions included establishing processes for consistent screening, developmental plan administration, review of prone positioning, access to therapies, and early intervention referrals.
Conclusion:
This targeted quality improvement project increased the use of inpatient practices to support gross motor development for infants with single ventricle CHD. Collaborative, interdisciplinary efforts remain critical for addressing neurodevelopmental challenges in this high-risk population.
Individuals at clinical high risk (CHR) for psychosis exhibit both baseline and progressive brain structural abnormalities. However, the extent to which these changes reflect neurobiological trajectories of illness progression versus iatrogenic effects of antipsychotic (AP) treatment remains unresolved. A total of 148 AP-naïve CHRs and 65 healthy controls (HCs) underwent baseline structural magnetic resonance imaging (MRI) scans. One hundred thirty CHRs received second-generation AP treatment and completed 2-month follow-up scans. HCs also completed the follow-up scans. We compared baseline and longitudinal brain volume changes between CHRs and HCs and explored the relationship between AP treatment and brain structural changes in CHR. At baseline, CHRs showed enlarged third and inferior lateral ventricles compared to HCs. Within CHRs, larger ventricular, as well as smaller hippocampus and amygdala volumes, were associated with more severe symptoms and poorer functioning. No cortical volume differences were observed between groups at baseline, nor were cortical volumes related to clinical symptoms. After 2-month AP treatment, CHRs exhibited continued ventricular enlargement, reduced accumbens volume, and widespread cortical volume loss relative to HCs. Notably, cortical volume reductions were dose-dependent, with higher AP dose correlating with more pronounced cortical reductions. Additionally, cortical volume changes were linked to treatment response, with high-dose responders showing more significant HC-referenced changes compared to high-dose non-responders, low-dose responders, and low-dose non-responders. Our findings underscore the complex, region-specific, and clinically relevant neuroanatomical changes in CHR individuals, emphasizing the critical need to account for AP exposure in CHR neuroimaging studies.
This systematic review evaluates specialized psychosocial and complex interventions for early bipolar disorder (BD), early borderline personality disorder (BPD), early depression, early psychosis, and first-episode mental illness in general (FEMI).
Methods
We included systematic reviews and randomized controlled trials (RCTs) of interventions with psychosocial components, excluding trials that focused on pharmacological-only interventions and stand-alone psychotherapies. Searches were conducted in January 2023 across five databases. Review quality was assessed using AMSTAR-2 and risk of bias for RCTs using the Cochrane tool.
Results
Ten studies met the inclusion criteria: seven reviews and three RCTs. High-to moderate-quality evidence supports complex psychosocial interventions combined with pharmacotherapy for early psychosis. The most robust effects were reductions in relapse and improvements in psychosocial functioning; additional benefits were observed for symptom burden, remission, treatment discontinuation, and hospital admissions. Benefits were most sustained in longer-duration, community-based programs. For early BD, limited evidence suggests that combining pharmacotherapy with family-focused therapy or structured psychoeducation may improve the course of illness and treatment satisfaction. One RCT in early BPD reported improved engagement with a developmentally tailored program. Two FEMI RCTs found that nurse-led psychoeducation and psychosocial programs improved in-patient duration, symptoms, insight, self-efficacy, quality of life, and engagement. No eligible studies addressed early-stage depression, indicating a notable evidence gap for multimodal psychosocial interventions.
Conclusions
Complex psychosocial interventions are strongly supported for early psychosis. Preliminary data in BD, BPD, and FEMI suggest consistent benefits for engagement, but further rigorous trials – especially in early depression – focusing on different outcomes – are required.
Psychiatric comorbidities are common in first-episode psychosis (FEP) and hinder recovery. Problem gambling (PBG), despite potentially serious clinical consequences, remains under-investigated in this population. This study aimed to estimate the incidence of PBG in FEP and identify predictive factors.
Methods
This prospective cohort study was conducted at two FEP programmes in Quebec, Canada. Individuals aged 18–35 years diagnosed with FEP between November-1-2019 and January-31-2023 were screened for PBG using the Problem Gambling Severity Index through May-1-2023. The primary outcome was incident PBG. Time-varying Cox regression models were used to estimate hazard ratios (HRs) for candidate predictors.
Results
Among 520 individuals without prior PBG (mean age = 24.6±4.0 years; 28.8% women), 18 developed PBG during a mean follow-up of 478 days, yielding an incidence rate of 2.6 cases/ 100 person-years. In site-adjusted analyses, white ethnicity (HR = 9.7; 95%CI = 1.3–74.8), incomplete high school education (HR = 2.8; 95%CI = 1.1–7.2), stimulant use disorder (HR=2.8; 95%CI = 1.0–7.3), use of D2/D3-5-HT1A partial agonists (HR = 4.6; 95%CI = 1.5–14.1), and prior non-problematic gambling (HR = 3.1; 95%CI = 1.1–8.4) predicted increased risk. Thirteen cases occurred during aripiprazole treatment, which remained associated with increased PBG risk after multivariable adjustment (adjusted HR = 4.7; 95%CI = 1.6–13.9).
Conclusions
Despite the limited number of incident cases, these results suggest that PBG is relatively common PBG and is associated with potential risk factors, including white ethnicity, incomplete high school education, stimulant use disorder, prior non-problematic gambling, and treatment with D2/D3-5-HT1A partial agonists, particularly aripiprazole. These findings underscore the importance of routine screening for PBG and risk-informed antipsychotic prescribing in FEP.
Demand currently greatly outweighs supply in teenage mental health, with statutory services and the third sector struggling to cope with the number of referrals. There is increasing interest in the possibility of using schools to provide mental health interventions. This pilot study looked at the feasibility of developing a version of an existing evidence-based transdiagnostic large-class didactic approach widely used in NHS adult services – ‘Stress Control’ – for use with teenagers as a universal early intervention/prevention approach taught by teachers within the Personal and Social Education (PSE) curriculum in a high school in a highly deprived area. PSE teachers were trained, over five hours, to deliver each of the eight sessions in single weekly periods. Measures of anxiety and depression (RCADS) and wellbeing (WEMBWS) were administered at pre- and post-intervention and at 9-month follow-up. Results suggest that teachers reported few problems in delivering the approach, seen as relevant by pupils and showed significant reduction in anxiety and depression and significant gains in wellbeing at post-intervention. These gains were maintained at 9-month follow-up. There appears to be potential in this model. One of its strengths appears to be the positive collaboration between the psychologist, teachers and pupils, which resulted in changes being made to the original model. Limitations of the study and suggestions for future research are given.
Key learning aims
(1) To learn if an evidence-based adult psychoeducational approach can be adapted to meet the needs of teenage pupils in a school in a deprived neighbourhood.
(2) To learn if teachers, with no training in mental health, can deliver this approach.
(3) To test the viability of the approach with an aim of creating a sustainable intervention.
Gaming disorder (GD) is increasingly recognized as a clinically significant condition, yet its implications in first-episode psychosis (FEP) remain largely unexplored. This perspective article focuses on the intersection of GD and FEP, highlighting key diagnostic and treatment challenges, including symptom overlap that complicates differential diagnosis, the absence of validated screening tools, and difficulties in sustained patient engagement. Drawing insights from substance use disorder management in FEP, we propose a preliminary clinical framework for integrating GD assessment and intervention into early intervention in psychosis programs. This approach prioritizes comprehensive evaluation, patient-centered care, and a harm-reduction model that supports digital well-being. Addressing GD inFEP populations is crucial for optimizing functional recovery and promoting a holistic, recovery-oriented approach to psychiatric care. Further research is needed to refine screening tools and validate tailored interventions in this population.
In the ultra-high risk for psychosis (UHR) field, it is unknown whether understanding symptom relationships, beyond symptom severity alone, may hold prognostic value and inform preventive care. In this study, network analysis was performed to examine the interconnections between baseline symptoms in UHR youth who did and did not transition to psychosis over three years.
Methods
In a sample selected from the UHR1000+ cohort, positive and basic symptoms were assessed using the Comprehensive Assessment of At-Risk Mental States. Network analyses and network comparison tests were performed.
Results
195 UHR youth transitioned to psychosis within three years and 346 did not. The two groups did not differ in the network structure, global strength (i.e., the overall level of connectivity between symptoms), or centrality of symptoms (i.e., their importance within networks). The transitioned group was characterized by unusual thought content not being connected to other symptoms; however, its centrality between networks was comparable. Across networks, impaired cognitive functioning connected disorganized speech to impaired emotional functioning, motor functioning, and tolerance to normal stress. Impaired bodily sensation connected perceptual abnormalities to other symptoms.
Conclusions
The networks of youth who transitioned and who did not transition were similar, indicating similar baseline symptom relationships. Across groups, unusual thought content, despite being traditionally associated with transition, had little to no interactions with other symptoms. Clinical manifestations that may need attention include impaired cognitive functioning, which connected several symptoms, and impaired bodily sensation. Future research using time series data may support progress toward individualized care.
Early intervention (EI) for first-episode psychosis (FEP) mainly focuses on adolescents and young adults. Previous evaluation demonstrated superiority of 2-year EI program (EASY) over standard care in outcome improvement in young people (15–25 years) with FEP in Hong-Kong. However, effectiveness of territory-wide extended EASY, which provides 3-year EI service also to adult patients aged ≥26 years, has not been systematically examined.
Methods
This study adopted historical control–case design, comparing patients aged 26–55 years who had received extended EI (EI-group, n = 160) with those managed by standard psychiatric care (SC-group, n = 160) prior to an implementation of extended EI service on a comprehensive range of outcomes encompassing duration of untreated psychosis (DUP), pathway to care, symptom severity, psychosocial functioning, subjective quality of life and service utilization over 3 years of psychiatric follow-up, using systematic medical-record review and follow-up interview assessment.
Results
Our results showed that EI-group had significantly shorter DUP than SC-group. Additionally, EI-group displayed fewer average positive symptoms in the first and second year of follow-up, lower levels of negative and depressive symptoms, better global and social functioning, and higher quality of life on physical domain than SC-group at 3 years of follow-up. Our findings indicate that adult FEP patients receiving 3-year extended EI service had better clinical and functional outcomes than those managed by standard psychiatric care.
Conclusions
Our results thus provide real-world evidence supporting the superiority and implementation of 3-year extended EASY program for adult FEP patients in shortening of treatment delay and improvement of symptom and functional outcomes.
Early-onset psychosis (EOP) is a severe mental disorder with a significant impact on affected children, young people and their families. Its assessment and diagnosis may be challenging, treatment approaches may not always lead to full remission of symptoms, and it is frequently associated with recurrent episodes and long-term disability. A comprehensive evaluation of psychotic symptoms, co-morbidities, physical health and environmental risk factors is likely to contribute to the holistic understanding of the child or adolescent with psychosis and provide the best possible management framework. A systematic approach to treatment with antipsychotic medication and psychosocial interventions should incorporate regular reviews of its effectiveness and adverse effects. Early intervention seems to lead to optimal outcomes through reducing the duration of untreated psychosis and providing input during the critical period after its onset when treatment can be most effective. Further research aiming to advance our understanding of the complex aetiology of psychotic disorders, effectiveness of management strategies, and necessary service provision is urgently needed.
The concept of prevention in health and welfare has long been recognised as crucial, yet its practical implementation remains complex. This chapter delves into the significance of prevention as a fundamental principle in addressing societal challenges and individual health outcomes. With a focus on the links between adversity, societal issues and health burdens, the economic rationale for preventive measures becomes apparent. Recent attention has been drawn to prevention and early intervention, particularly in light of the long-term consequences of early adversity on physical and mental health. Government initiatives in the UK, such as the establishment of Health and Wellbeing Boards and emphasis on prevention in health services, underscore the growing importance of prevention strategies. The impact of the Covid-19 pandemic has further highlighted the need for proactive prevention measures in health and welfare policies. This chapter explores the meaning of prevention, theoretical considerations, practical clinical strategies and the role of senior health professionals in promoting prevention in children’s mental health services.
The chapter will help you to be able to describe NICE recommendations for responding immediately after trauma, utilise guidelines in your clinical practice and developing service policy, offer pragmatic and compassionate responses to individuals presenting with very recent trauma exposure

Chapter 50 covers the topic of child and adolescent mental health services. Through a case vignette with topical MCQs for consolidation of learning, readers are brought through the management of young patients with psychiatric disorders from first presentation to subsequent complications of the conditions and its treatment. Things covered include the general principles of prescribing in children and adolescent patients with psychiatric disorders, the use of antidepressants, the use of mood stabilisers, the use of antipsychotics, treatment of anxiety disorders.
Psychological therapy (PT) along with antipsychotic medication is the recommended first line of treatment for first-episode psychosis (FEP). We investigated whether ethnicity, clinical, pathways to care (PtC) characteristics, and access to early intervention service (EIS) influenced the offer, uptake, and type of PT in an FEP sample.
Methods
We used data from the Clinical Record Interactive Search-First Episode Psychosis study. Inferential statistics determined associations between ethnicity, clinical, PtC, and PT offer/uptake. Multivariable logistic regression estimated the odds of being offered a PT and type of PT by ethnicity, clinical and PtC characteristics adjusting for confounders.
Results
Of the 558 patients included, 195 (34.6%) were offered a PT, and 193 accepted. Cognitive behavioral therapy (CBT) (n = 165 of 195; 84.1%) was commonly offered than group therapy (n = 30 of 195; 13.3%). Patients who presented via an EIS (adj. OR = 2.24; 95%CI 1.39–3.59) were more likely to be offered a PT compared with those in non-EIS. Among the patients eligible for an EIS, Black African (adj. OR = 0.49; 95%CI = 0.25–0.94), Black Caribbean (adj. OR = 0.45; 95%CI = 0.21–0.97) patients were less likely to be offered CBT compared with their White British counterparts. Patients with a moderate onset of psychosis (adj. OR = 0.34; 95%CI = 0.15–0.73) had a reduced likelihood of receiving CBT compared with an acute onset.
Conclusions
Accessing EIS during FEP increased the likelihood of being offered a PT. However, treatment inequalities remain by ethnicity and clinical characteristics.
Dissociative experiences are common transdiagnostically, and particularly prevalent in psychosis. Such experiences have long been under-recognised in routine clinical practice, despite evidence that dissociation is related to clinical complexity and increased risk of self-harm and suicidality. Adopting a symptom-specific, targeted approach to conceptualisation and intervention for dissociation may help improve outcomes.
Aims:
The evidence base for psychological treatments targeting dissociation is building, but training and guidance for clinicians remains sparse. This review outlines a preliminary approach to the treatment of a subtype of dissociative experience (felt sense of anomaly dissociation), based on emerging research evidence and clinical practice. The guidance is tailored to the context of psychosis, and may also have broader clinical relevance.
Method:
We present symptom-specific guidance for clinicians, including factors to consider in the assessment, formulation, and intervention for felt sense of anomaly dissociation in the context of psychosis, and reflections on process issues. We present a cognitive behavioural model, where affect-related changes are interpreted as an internal threat, driving a maintenance cycle of catastrophic appraisals and safety behaviours. Using this formulation, evidence-based therapy techniques familiar to most readers can then be applied.
Conclusions:
It is important for clinicians to consider dissociation. As well as generating new avenues for translational intervention research, we anticipate that the novel insights and specific advice outlined here will be of use to professionals working with dissociation in psychosis (and beyond). Encouragingly, we demonstrate that widely used, evidence-based skills and techniques can be employed to address distress arising from dissociation.
Brain tumors are associated with negative changes in sense of self and increased distress early in the illness trajectory. Dignity Therapy (DT) is a brief 2-session therapeutic intervention for patients at end-of-life (EOL) that helps conserve a patient’s sense of dignity or self. DT has shown positive results for patients at EOL including increased meaning, improved quality of life (QOL), and reduced distress, with limited research to date on patients early in their illness trajectory (non-EOL). This pre-post design pilot study investigated the benefits and feasibility of DT for 2 groups of patients with incurable brain tumors.
Methods
A total of 51 participants were recruited, of whom 39 participated. Participants were grouped as EOL (prognosis < 1 year, n = 21) and non-EOL (prognosis > 1 year, n = 18). Participants completed self-report measures to determine changes in QOL, psychosocial well-being (i.e., spiritual well-being, connection, and posttraumatic growth), and death anxiety, at baseline, 1 week, and 5 weeks post-intervention.
Results
The intervention had a high completion rate, with 37 of 39 participants (95%) completing DT. Linear regression models fitted with generalized estimating equations (GEEs) showed within- and between-group significant changes in all domains for both groups, but were particularly beneficial for non-EOL participants.
Significance of results
This study demonstrated that DT effectively enhanced psychosocial well-being in patients with brain tumors, including reductions in death anxiety and dignity-related distress. Non-EOL participants benefited most and had higher completion rates, highlighting the intervention’s feasibility and the need for further research in earlier stages of terminal illness.
Preclinical evidence suggests that diazepam enhances hippocampal γ-aminobutyric acid (GABA) signalling and normalises a psychosis-relevant cortico-limbic-striatal circuit. Hippocampal network dysconnectivity, particularly from the CA1 subfield, is evident in people at clinical high-risk for psychosis (CHR-P), representing a potential treatment target. This study aimed to forward-translate this preclinical evidence.
Methods
In this randomised, double-blind, placebo-controlled study, 18 CHR-P individuals underwent resting-state functional magnetic resonance imaging twice, once following a 5 mg dose of diazepam and once following a placebo. They were compared to 20 healthy controls (HC) who did not receive diazepam/placebo. Functional connectivity (FC) between the hippocampal CA1 subfield and the nucleus accumbens (NAc), amygdala, and ventromedial prefrontal cortex (vmPFC) was calculated. Mixed-effects models investigated the effect of group (CHR-P placebo/diazepam vs. HC) and condition (CHR-P diazepam vs. placebo) on CA1-to-region FC.
Results
In the placebo condition, CHR-P individuals showed significantly lower CA1-vmPFC (Z = 3.17, PFWE = 0.002) and CA1-NAc (Z = 2.94, PFWE = 0.005) FC compared to HC. In the diazepam condition, CA1-vmPFC FC was significantly increased (Z = 4.13, PFWE = 0.008) compared to placebo in CHR-P individuals, and both CA1-vmPFC and CA1-NAc FC were normalised to HC levels. In contrast, compared to HC, CA1-amygdala FC was significantly lower contralaterally and higher ipsilaterally in CHR-P individuals in both the placebo and diazepam conditions (lower: placebo Z = 3.46, PFWE = 0.002, diazepam Z = 3.33, PFWE = 0.003; higher: placebo Z = 4.48, PFWE < 0.001, diazepam Z = 4.22, PFWE < 0.001).
Conclusions
This study demonstrates that diazepam can partially restore hippocampal CA1 dysconnectivity in CHR-P individuals, suggesting that modulation of GABAergic function might be useful in the treatment of this clinical group.
Roger was a 60-year-old man living with both HIV and schizophrenia who was admitted to the hospital for treatment of a chronic obstructive pulmonary disease exacerbation. He was referred to the psychiatry consultation-liaison team due to persistent psychotic symptoms that had not responded to multiple antipsychotic trials. Roger’s psychiatric history revealed a diagnosis of schizophrenia in early adulthood, marked by hallucinations and delusions of grandeur. Over the next 4 decades, he cycled through jails, prisons, shelters, and periods of homelessness. Though intermittently connected with outpatient care, his illness remained poorly controlled.
