Investigating expressed emotion in individuals at-risk of developing psychosis and their families over 12 months.

High levels of expressed emotion (EE) are present in families of individuals with an at-risk mental state (ARMS) of psychosis and can negatively impact on service users' functioning and symptoms, as well as relatives' psychological wellbeing. OBJECTIVES: This is the first longitudinal study to assess EE from the family/carers' perspective, as well as the service users' perceptions of the family/carers' EE. We explored the effects of EE on transition risk and outcomes of depression, worry, and anxiety. METHODS: Questionnaires were completed by 70 ARMS individuals and 70 family/carers at three time points: baseline, 6 and 12 months. All participants completed measures of anxiety, depression, and worry, plus a version of the Family Questionnaire to assess EE. RESULTS: EE scores reduced over time for both service users and family/carers. High EE perceived by service users at 6 months was associated with higher transition to psychosis at 12 months. High-EE levels at baseline were associated with higher levels of service user depression and family/carer anxiety at 12 months. Higher family/carer total EE scores were associated with less contact with the service user and higher levels of worry. CONCLUSIONS: Novel implications suggest that interventions to reduce high EE in families of people with ARMS would benefit service users by protecting them from higher levels of depression and transition to psychosis. Reducing high-EE attitudes would also benefit the family/carers by reducing levels of anxiety and worry. Family interventions focussing on multiple perceptions of the home environment could help to direct services and prevent negative psychological outcomes for all family members.

"I don't think I took her fears seriously": Exploring the experiences of family members of individuals at-risk of developing psychosis over 12 months.

Individuals with an at-risk mental state (ARMS) of psychosis experience high levels of distress, anxiety, low mood, and suicidal ideation. Families of ARMS individuals provide significant support but are often neglected by services. This study is the first of its kind to use a novel longitudinal qualitative methodology to directly compare family/carers' earlier experiences supporting ARMS individuals to 12 months later. This provides a more ecologically valid insight into how perceptions change over time and how family/carers adapt. Semistructured interviews were conducted with 10 family/carers at two points within a 12-month period. This study was embedded within a randomized control trial, the Individual and Family Cognitive Behavioural Therapy trial. Interview transcripts were analysed using thematic analysis, with a focus on how experiences and reactions for family/carers changed over time. Over 12 months, four factors were important for family/carers to facilitate their caring role. These were summarized in the thematic map (LACE model): Looking after your own well-being; Accessing additional support from family intervention; Communicating openly with the individual; and Engaging with services for the individual. All four aspects of the model were important in improving family communication, meeting family/carers' unmet needs, and helping them to feel more confident and less isolated in their carer role. Novel implications suggest that when feasible, services should involve family/carers of ARMS individuals in sessions and explore family/carer support strategies in managing their own distress. The most significant insight was the need to develop family/carer resources to educate, normalize, and validate their own experiences.

What does recovery mean to young people with mental health difficulties? - "It's not this magical unspoken thing, it's just recovery".

Background: There is extensive literature documenting the nature of recovery in mental health in adult populations, but there is very little exploring its nature and meaning for young people.Aims: To gain a detailed understanding from the perspective of young people about the concept of recovery in young people's mental health.Method: Semi structured interviews were conducted with 23 young people. Interviews were transcribed verbatim and analysed using thematic analysis.Results: Themes emerging from the interviews included young people's dynamic conceptualisations of recovery, awareness of others views of recovery, polarised goals of recovery, and facilitators and barriers of recovery.Conclusions: To be relevant for young people, the mental health recovery model must incorporate individual needs, developmental considerations and fluctuations in goals. It must also be embedded within the young person's ecological system such as family, friends and school, and be focussed around an explicit and collaborative recovery discussion with the young person.

Delivery of cognitive-behaviour therapy for psychosis: a service user preference trial.

BACKGROUND: Clinical guidelines recommend cognitive behaviour therapy (CBT) for people with psychosis, however, implementation is poor and not everyone wishes to engage with therapy. Understanding service user (SU) preferences for receiving such treatments is a priority for services. AIMS: To explore SU preferences and outcomes of different methods of delivering CBT for psychosis. METHOD: SUs experiencing psychosis could choose between treatment as usual (TAU); TAU plus telephone-delivered CBT with self-help, CBT recovery manual (TS); high support CBT (HS - TAU plus TS plus group sessions) or randomisation. Participants received their option of choice and were followed-up on several outcomes over 9 and 15 months. RESULTS: Of 89 people recruited, three chose to be randomised and 86 expressed a treatment preference (32 chose TAU, 34 chose TS, 23 chose HS). There were few differences between those who chose therapy compared to those who chose TAU. Those who had more positive impacts from their symptoms were significantly more likely to choose TAU. CONCLUSIONS: Most people had strong preferences about treatment delivery and a substantial number did not wish to receive additional therapy. These findings have to be considered when planning and allocating resources for people with psychosis.

Longitudinal predictors of subjective recovery in psychosis.

BACKGROUND: Research has highlighted the importance of recovery as defined by the service user, and suggests a link to negative emotion, although little is known about the role of negative emotion in predicting subjective recovery. AIMS: To investigate longitudinal predictors of variability in recovery scores with a focus on the role of negative emotion. METHOD: Participants (n = 110) with experience of psychosis completed measures of psychiatric symptoms, social functioning, subjective recovery, depression, hopelessness and self-esteem at baseline and 6 months later. Path analysis was used to examine predictive factors for recovery and negative emotion. RESULTS: Subjective recovery scores were predicted by negative emotion, positive self-esteem and hopelessness, and to a lesser extent by symptoms and functioning. Current recovery score was not predicted by past recovery score after accounting for past symptoms, current hopelessness and current positive self-esteem. CONCLUSIONS: Psychosocial factors and negative emotion appear to be the strongest longitudinal predictors of variation in subjective recovery, rather than psychiatric symptoms.

Experiential avoidance and appraisals of voices as predictors of voice-related distress.

OBJECTIVES: Research has suggested that the extent to which voices (i.e., auditory verbal hallucinations) are experienced as distressing might be influenced by negative beliefs about voices as well as maladaptive metacognitive styles involving the negative appraisal and maladaptive control of mental experiences. This cross-sectional study examined the contribution of both specific appraisals of voices and a metacognitive factor (i.e., experiential avoidance) to voice-related distress. METHODS: Self-report measurers of voice characteristics (voice frequency, duration as well as amount and intensity of voice-related distress), experiential avoidance, and appraisals of voices were collected in a sample of 101 voice-hearers. RESULTS: Experiential avoidance and negative beliefs about voices were associated with higher levels of voice-related distress, but not to measures of voice frequency and duration. Experiential avoidance and negative 'metaphysical' beliefs about voices were significant predictors of voice-related distress even after accounting for the effect of frequency and duration of voices, and explained similar proportions of unique variance in distress. CONCLUSIONS: These findings suggest that the appraisals of voices and experiential avoidance are predictive of voice-related distress and that cognitive-behavioural interventions targeting both voice-specific appraisals and general maladaptive metacognitive processes could prove useful treatment approaches for clients with distressing voices. PRACTITIONER POINTS: Experiential avoidance (EA) and negative appraisals predict voice-related distress caused by voices, but not their frequency and duration. Interventions for voices should consider targeting EA and negative appraisals (e.g., cognitive-behavioural therapy, Acceptance and Commitment Therapy) to ameliorate distress.

Recovery-focused cognitive-behavioural therapy for recent-onset bipolar disorder: randomised controlled pilot trial.

BACKGROUND: Despite evidence for the effectiveness of structured psychological therapies for bipolar disorder no psychological interventions have been specifically designed to enhance personal recovery for individuals with recent-onset bipolar disorder. AIMS: A pilot study to assess the feasibility and effectiveness of a new intervention, recovery-focused cognitive-behavioural therapy (CBT), designed in collaboration with individuals with recent-onset bipolar disorder intended to improve clinical and personal recovery outcomes. METHOD: A single, blind randomised controlled trial compared treatment as usual (TAU) with recovery-focused CBT plus TAU (n = 67). RESULTS: Recruitment and follow-up rates within 10% of pre-planned targets to 12-month follow-up were achieved. An average of 14.15 h (s.d. = 4.21) of recovery-focused CBT were attended out of a potential maximum of 18 h. Compared with TAU, recovery-focused CBT significantly improved personal recovery up to 12-month follow-up (Bipolar Recovery Questionnaire mean score 310.87, 95% CI 75.00-546.74 (s.e. = 120.34), P = 0.010, d = 0.62) and increased time to any mood relapse during up to 15 months follow-up (χ2 = 7.64, P<0.006, estimated hazard ratio (HR) = 0.38, 95% CI 0.18-0.78). Groups did not differ with respect to medication adherence. CONCLUSIONS: Recovery-focused CBT seems promising with respect to feasibility and potential clinical effectiveness. Clinical- and cost-effectiveness now need to be reliably estimated in a definitive trial.

Motiv8: a study protocol for a cluster-randomised feasibility trial of a weight management intervention for adults with severe mental illness in secure forensic services.

INTRODUCTION: People with severe mental illness have physical comorbidities which result in significant reductions in quality of life and premature mortality. Effective interventions are required that are suitable for people in secure forensic mental health services. We conducted pilot work of a multidisciplinary weight management intervention (Motiv8) which showed improvements in physical and mental health and high levels of satisfaction. We aim to test the feasibility of Motiv8 under cluster randomised conditions, with an aim to investigate the acceptability, feasibility and potential effectiveness of this intervention to supplement standard secure care. METHODS AND ANALYSIS: A randomised waitlist-controlled feasibility trial of a lifestyle intervention (Motiv8) + TAU compared with TAU (+ Motiv8 waitlist) for adults on secure mental health units will be conducted. Thirty-two people (4 cohorts) will be recruited from secure services in Greater Manchester Mental Health NHS Foundation Trust. Participants will be randomly allocated to Motiv8 or TAU + Motiv8 waitlist. All participants will receive Motiv8 during the trial. Assessor-blinded physical/mental health and lifestyle assessments will be conducted at baseline, 10 weeks (post-intervention/waitlist), and after 12 weeks (post-waitlist intervention/follow-up). Motiv8 is a multidisciplinary intervention including exercise sessions, cooking/nutrition classes, physical health education, psychology sessions, sleep hygiene, peer support and medication review by pharmacy. A nested qualitative study will be conducted with a subsample of participants (n = 10) to explore their experiences of taking part. The analysis will focus on feasibility outcomes and tabulated success indicators of the study (e.g. Recruitment rates, retention rates, follow-up retention and response rates, attendance at sessions, the experience of involvement in the trial and delivery of the intervention, assessment of safety, development of a manualised intervention). Thematic analysis will be conducted through qualitative interviews. The analysis will aim to inform the development of a definitive trial. ETHICS AND DISSEMINATION: The trial has been granted ethical approval from the NHS Health Research Authority and adopted onto the UK Clinical Research Network Portfolio. Findings will be disseminated via peer-reviewed publications, professional and public networks, conferences and clinical services. TRIAL REGISTRATION: ISRCTN13539285.

A randomised controlled trial of recovery focused CBT for individuals with early bipolar disorder.

BACKGROUND: There is increasing evidence for the effectiveness of structured psychological therapies for bipolar disorder. To date however there have been no psychological interventions specifically designed for individuals with early bipolar disorder. The primary objective of this trial is to establish the acceptability and feasibility of a new CBT based intervention (Recovery focused CBT; RfCBT) designed in collaboration with individuals with early bipolar disorder intended to improve clinical and personal recovery outcomes. METHODS AND DESIGN: This article describes a single blind randomised controlled trial to assess the feasibility and acceptability of RfCBT compared with treatment as usual. Participants will be recruited from across the North West of England from specialist mental health services and through primary care and self referral. The primary outcome of the study is the feasibility and acceptability of RfCBT as indicated by recruitment to target and retention to follow-up as well as absence of untoward incidents associated with RfCBT. We also intend to estimate the effect size of the impact of the intervention on recovery and mood outcomes and explore potential process measures (self appraisal, stigma, hope and self esteem). DISCUSSION: This is the first trial of recovery informed CBT for early bipolar disorder and will therefore be of interest to researchers in this area as well as indicating the wider potential for evaluating approaches to the recovery informed treatment of recent onset severe mental illness in general. TRIAL REGISTRATION NUMBER: ISRCTN43062149.

Six years on: a prospective cohort study of male juvenile offenders in secure care.

Longitudinal studies are helpful in understanding developmental trajectories and recognising opportunities for early intervention. This paper describes the long-term needs and mental health of an initial sample of male juvenile offenders, now adults 6 years after their index admission to secure care. In this prospective cohort study of 97 male juvenile offenders admitted to secure, offenders were assessed initially on admission, 2 and 6 years later. Interviews were conducted with 54 offenders at the 6-year follow-up and included an assessment of psychosocial need, mental health and psychopathy. Outcome data on offending behaviour were collected on a total of 71 offenders. Persistent offenders have needs in multiple domains as they transition into adulthood. The majority of offenders were single and about a half were in neither employment nor training. Almost nine out of ten offenders had a substance misuse disorder and a similar number met the criteria for a diagnosis of antisocial personality disorder. Substance misuse in adolescence was strongly correlated with later substance misuse in adulthood, emphasising the importance of early intervention. A diagnosis of antisocial personality disorder and living with friends and family were both significantly associated with persistent offending behaviour. Many offenders continued to reoffend despite receiving offence-related interventions and custodial care. Interventions currently aimed at reducing recidivism in more severe offenders appear to be ineffective. Persistent offenders would benefit from a multi-modal approach based on individual needs, rather than receiving generic interventions.

Recovery from psychosis: a user informed review of self-report instruments for measuring recovery.

BACKGROUND: Mental health services are being encouraged to adopt a recovery approach, creating a requirement for standardised measures of recovery to be developed and embedded within services. Measurement of this unique concept is inherently difficult, but it is feasible and valid provided that service users and clinicians work collaboratively. AIMS: To evaluate which measures of recovery have clinical utility and are acceptable to service users. METHOD: Instruments included in this review are (1) quantitative self-report measures, (2) published in a peer reviewed English language journal and (3) designed to measure personal recovery. The review team included two service-user researchers to allow evaluation of acceptability to service users. RESULTS: Twenty-five measures of recovery were identified; six of these met the inclusion criteria. A summary table of the measures is included to enable readers to make an informed choice of measure for their specific needs, along with an overview of each measure. CONCLUSIONS: The Recovery Assessment Scale appears to be the most acceptable and valid measure currently available. No "gold-standard" measure of recovery has been developed to date. Further research is required to examine the longitudinal reliability of existing tools, and their utility within clinical services and as outcome measures.

Subjective judgements of perceived recovery from psychosis.

BACKGROUND: Recent conceptualisations of recovery from psychosis have recognised the importance of psychosocial aspects as well as the presence or absence of symptoms. Qualitative research and personal accounts of recovery highlight its subjective and idiosyncratic nature. This study aims to explore subjective judgements of recovery from the perspective of service users, and examine the agreement and consistency in such judgements across different measures of recovery. It also aims to investigate the relationships between subjective judgements of recovery and psychosocial factors. METHODS: A total of 122 participants with experience of psychosis completed three self-report measures of recovery judgements, as well as measures of psychological functioning (including self-esteem, optimism, anxiety and depression) and socio-demographic measures. RESULTS: Judgements about recovery from psychosis across the three measures, while showing a trend, also show within-person variability. Recovery judgements were significantly correlated with each other and with all psychological variables, but were not associated with socio-demographic variables except for age. Regression analyses showed that recovery judgements were predicted by mood, optimism and self-esteem. CONCLUSIONS: Subjective judgements of recovery were seen to be idiosyncratic, with people appearing to have different thresholds for perceived recovery. The conclusions of the existing qualitative research and first-person accounts appear generalisable to larger samples.

'If he feels better I'll feel better' relationships with individuals at high-risk of developing psychosis.

AIM: A large proportion of individuals with an at-risk mental state (ARMS) live at home and are supported by their families. Recommended treatment includes family intervention (FI), and therefore, understanding relationships between individuals with an ARMS and their family members is key. This study aimed to provide a more holistic exploration of relationships within families of individuals with an ARMS by reporting the perceived impact of the condition on other family members including sibling and romantic relationships. METHOD: Fourteen semi-structured interviews with family members were analysed using thematic analysis. RESULTS: Parents wanted to maintain a safe family environment for all family members. This can result in spending less time with siblings who impacted on siblings' relationships with the service user and other family members. Romantic relationships were negatively impacted when there was unclear communication between the couple, as well as the partner's response and understanding of the ARMS condition. Clear communication across sibling and romantic relationships facilitated helpful family/carer's behaviour and understanding of the individuals' mental distress. CONCLUSION: FI should explore and support families with changes in sibling and romantic relationships. More research is needed to understand siblings' perspectives in families with individuals experiencing an ARMS and to develop resources to support partners and families in changes within their sexual and romantic relationships.

Therapeutic relationships in child and adolescent mental health services: A Delphi study with young people, carers and clinicians.

Therapeutic relationships have been widely recognized as crucial to good outcomes in psychotherapy. However, there is comparatively little research on what constitutes and impacts therapeutic relationships in the context of child and adolescent mental health services (CAMHS). Relationships within CAMHS are inherently complex, with multiple relationships taking place between young people, parents or carers and staff members of various disciplines. The Delphi method was used to gain consensus regarding the definition of therapeutic relationships, what helps to build and what hinders the formation of a good relationship in the context of CAMHS. Three expert groups (young people, carers and staff) totalling 88 participants were invited to complete an online Delphi survey across three rounds. Consensus was reached to define the therapeutic relationship as trust, reliability and absence of judgemental attitudes (n = 19 statements). Factors that help build good relationships predominantly referred to staff behaviours of setting up open communication channels, showing acceptance of the young person's difficulties and being consistent (n = 88 consensus agreement statements). Factors that hindered a good relationship were inconsistencies and lack of clear communication between all groups (n = 18 consensus agreement statements). Effective therapeutic relationships require key behaviours and approaches from clinicians. It is essential that staff members are open and honest in facilitating discussions about parental involvement within the relationship and that staff provide consistent and trusting support to young people and family members. Our findings demonstrate that key stakeholders agree on important aspects and that these could be a catalyst for renewed training and support structures.

Physical health interventions on adolescent mental health inpatient units: A systematic review and call to action.

AIM: Physical health inequalities experienced by people with mental health conditions are labelled an international scandal; due to the 15 to 30-year gap in life expectancy, driven mostly by physical health conditions. Lifestyle interventions are recommended to prevent the onset of poor physical health in people with mental illness. Yet, there is less high-quality evidence for adolescents, particularly those in inpatient settings. We aimed to assess existing literature reporting physical health or lifestyle interventions conducted on adolescent mental health inpatient units. METHOD: An electronic search of MEDLINE, PsycINFO, Embase, the Cochrane Central Register of Controlled Trials and AMED was conducted on 13th June 2019. Eligible studies included peer-reviewed English language research articles of physical health interventions delivered within child and adolescent mental health inpatient services. A narrative synthesis was conducted on the data. RESULTS: Only three studies were identified implementing health interventions for adolescent inpatients. The interventions consisted of two physical health interventions aiming to increase activity levels within routine care (one gym-based, one sports led) and a yoga intervention. Outcome measurements varied and benefits were observed in relation to overall health (HONOSCA), physical health (waist, hip and chest circumference) and behaviour. CONCLUSIONS: Although preliminary results suggest lifestyle interventions may be feasible and beneficial for this group, more work is needed to fully understand the best way to implement these interventions within adolescent clinical settings. Adolescent inpatients are an important target for such interventions, affording the opportunity to prevent the onset of physical comorbidities.

The clinical and behavioral cardiometabolic risk of children and young people on mental health inpatient units: A systematic review and meta-analysis.

OBJECTIVE: Serious mental illness is associated with physical health comorbidities, however most research has focused on adults. We aimed to synthesise existing literature on clinical and behavioral cardiometabolic risk factors of young people on mental health inpatient units. METHODS: A systematic review and meta-analysis was conducted, using electronic searches of PsycINFO, EMBASE, AMED, Cochrane Central Register of Controlled Trials, and Ovid MEDLINE. Eligible studies included child/adolescent mental health inpatient units for <25 years, reporting clinical/behavioral cardiometabolic risk factors. Studies containing adult samples, case-studies, or eating disorder populations were excluded. The main clinical outcome was weight, and main behavioral outcome was tobacco use. RESULTS: Thirty-nine studies were identified (n = 809,185). Pooled prevalence rates of young people who were overweight (BMI > 25) was 32.4% (95% CI 26.1%-39.5%; n = 2789), and who were obese (BMI > 30) was 15.5% (95% CI 4.5%-41.6%; n = 2612). Pooled prevalence rates for tobacco use was 51.5% (95% CI 32.2-70.2; N = 804,018). Early signs of metabolic risk were observed; elevated blood cholesterol, presence of physical health conditions, and behavioral risk factors (e.g. physical inactivity). CONCLUSIONS: This review highlights the vulnerability of young people admitted to inpatient units and emphasises the opportunity to efficiently monitor, treat and intervene to target physical and mental health.

"It felt very special, it felt customised to me"-A qualitative investigation of the experiences of participating in a clinical trial of CBT for young people at risk of bipolar disorder.

OBJECTIVES: The Bipolar at Risk Trial (BART) was a feasibility randomized controlled trial investigating cognitive behavioral therapy (CBT) compared with treatment as usual (TAU) in young people at high risk of developing bipolar disorder (BD). This qualitative study aimed to investigate participants' experiences of trial involvement, and the acceptability of CBT for this population. DESIGN: Participants were those identified as being at risk of bipolar disorder, determined by current symptoms or family history. A purposive sample of twenty-one participants from both the intervention and TAU arms of the trial was recruited. METHODS: Twenty-one semi-structured interviews were conducted by service user researchers (13 participants had received therapy and 8 TAU). Interviews were audio recorded with consent from participants and transcribed verbatim. NVivo 11 Pro software was used to conduct an inductive thematic analysis. RESULTS: Super-ordinate themes were "adaptability and flexibility," "feeling understood and valued," and "relevance of study and intervention" which had two sub-themes-"value of the trial therapy" and "acceptability of trial processes." Participating in the trial and having therapy enabled participants to feel understood and valued by research assistants (RAs) and therapists. Participants viewed therapy as relevant to their current concerns and valued adaptability and flexibility of RAs and therapists. CONCLUSIONS: Findings highlight the importance and value of flexibility, adaptability, and understanding in relationships between participants and trial staff. Findings also indicate that the trial processes and CBT focusing on mood swings are acceptable and relevant to participants from this at risk population. PRACTITIONER POINTS: Young people at risk of bipolar disorder value a flexible approach to assessments and therapy, developing a rapport with research assistants and therapists and opening up to them when they feel comfortable to do so. CBT focusing on coping with mood swings was acceptable to the majority of participants who received it and it was perceived as helpful in ways that were personal to each participant.

Combined individual and family therapy in comparison to treatment as usual for people at-risk of psychosis: A feasibility study (IF CBT): Trial rationale, methodology and baseline characteristics.

AIMS: Current National Institute for Health and Care Excellence (NICE) guidelines for psychosis recommend psychological therapy with or without family intervention for individuals at-risk of developing psychosis. NICE guidelines have a specific research recommendation to investigate the clinical and cost effectiveness of combined individual and family intervention. We report the rationale, design and baseline characteristics of a feasibility study which aimed to investigate combined Individual and Family Cognitive Behavioural Therapy (IFCBT) for those at-risk of developing psychosis. METHODS: The IFCBT study was a single blind, pilot randomized controlled trial (RCT) to compare a combined individual and family Cognitive Behavioural Therapy (CBT) intervention to treatment as usual. Participants were assessed using the Comprehensive Assessment of the At-risk Mental State (CAARMS) and randomly allocated to either therapy or enhanced treatment as usual (ETAU). All participants were followed up at 6 and 12 months. Primary feasibility outcomes were recruitment and retention of participants. Secondary outcomes included transition to psychosis and assessment of mood, anxiety and the relationship of the individual and nominated family member. RESULTS: We report data showing entry into the study from initial enquiry to randomization. We report the characteristics of the recruited sample of individuals (n = 70) and family members (n = 70) at baseline. CONCLUSIONS: The study recruited to 92% of target demonstrating it is feasible to identify and recruit participants. Our study aimed to add to the current evidence base regarding the utility of family interventions for people at-risk of psychosis.

The Early Youth Engagement in first episode psychosis (EYE-2) study: pragmatic cluster randomised controlled trial of implementation, effectiveness and cost-effectiveness of a team-based motivational engagement intervention to improve engagement.

BACKGROUND: Early Intervention in Psychosis (EIP) services improve health outcomes for young people with psychosis in the medium-long term, but 25% of young people disengage in the first 12 months with costs to their mental health, families, society and the NHS. This study will evaluate the effectiveness, cost-effectiveness and implementation of a team-based motivational Early Youth Engagement (EYE-2) intervention. METHOD: The study design is a cluster randomised controlled trial (RCT) with economic evaluation, comparing the EYE-2 intervention + standardised EIP service to standardised EIP service alone, with randomisation at the team level. A process evaluation will evaluate the delivery of the intervention qualitatively and quantitatively across contexts. The setting is 20 EIP teams in 5 sites: Manchester, South London, East Anglia, Thames Valley and Hampshire. Participants are young people (14-35 years) with first episode psychosis, and EIP staff. The intervention is the team-based motivational engagement (EYE-2) intervention, delivered alongside standardised EIP services, and supported by additional training, website, booklets and social groups. The comparator is the standardised EIP service. Both interventions are delivered by EIP clinicians. The primary outcome is time to disengagement (time in days from date of allocation to care coordinator to date of last contact following refusal to engage with EIP service, or lack of response to EIP contact for a consecutive 3-month period). Secondary outcomes include mental and physical health, deaths, social and occupational function, recovery, satisfaction and service use at 6, 12, 18 and 24 months. A 12-month within-trial economic evaluation will investigate cost-effectiveness from a societal perspective and from an NHS perspective. DISCUSSION: The trial will provide the first test of an engagement intervention in standardised care, with the potential for significant impact on the mental health and wellbeing of young people and their families, and economic benefits for services. The intervention will be highly scalable, supported by the toolkit including manuals, commissioning guide, training and resources, adapted to meet the needs of the diverse EIP population, and based on an in-depth process evaluation.
