The poor health of unpaid carers is well-documented. Evidence also highlights that carers can experience high levels of domestic violence and abuse (DVA). However, links between DVA victimisation and health outcomes in carers remains largely overlooked. We examined DVA prevalence in carers and non-carers, and the relationship between carers’ DVA experience and health morbidities. We analysed data from a general population probability sample survey of 6,971 adults (aged ≥ 16 years) in England. Multivariable logistic regression models examined associations between caregiving, DVA experience, and mental and physical health morbidities (i.e., common mental disorders (CMD), probable post-traumatic stress disorder (PTSD), harmful alcohol use and chronic physical health conditions), adjusting for demographic and socioeconomic factors. One person in five reported caring responsibilities. Caring was associated with higher odds of CMD and chronic physical health conditions. One in three carers reported experiencing DVA in adulthood, and carers were more likely to be victims of DVA than non-carers. In carers who experienced DVA, compared to carers reporting no DVA, adjusted odds of CMD (aOR 2.88, 95

Background Recent network models propose that mutual interaction between symptoms has an important bearing on the onset of schizophrenic disorder. In particular, cross-sectional studies suggest that affective symptoms may influence the emergence of psychotic symptoms. However, longitudinal analysis offers a more compelling test for causation: the European Schizophrenia Cohort (EuroSC) provides data suitable for this purpose. We predicted that the persistence of psychotic symptoms would be driven by the continuing presence of affective disturbance. Methods EuroSC included 1208 patients randomly sampled from outpatient services in France, Germany and the UK. Initial measures of psychotic and affective symptoms were repeated four times at 6-month intervals, thereby furnishing five time-points. To examine interactions between symptoms both within and between time-slices, we adopted a novel technique for modelling longitudinal data in psychiatry. This was a form of Bayesian network analysis that involved learning dynamic directed acyclic graphs (DAGs). Results Our DAG analysis suggests that the main drivers of symptoms in this long-term sample were delusions and paranoid thinking. These led to affective disturbance, not vice versa as we initially predicted. The enduring relationship between symptoms was unaffected by whether patients were receiving first- or second-generation antipsychotic medication. Conclusions In this cohort of people with chronic schizophrenia treated with medication, symptoms were essentially stable over long periods. However, affective symptoms appeared driven by the persistence of delusions and persecutory thinking, a finding not previously reported. Although our findings as ever remain hostage to unmeasured confounders, these enduring psychotic symptoms might nevertheless be appropriate candidates for directly targeted psychological interventions.

BACKGROUND:Sexual abuse and bullying are associated with poor mental health in adulthood. We previously established a clear relationship between bullying and symptoms of psychosis. Similarly, we would expect sexual abuse to be linked to the emergence of psychotic symptoms, through effects on negative affect. METHOD:We analysed English data from the Adult Psychiatric Morbidity Surveys, carried out in 2007 (N = 5954) and 2014 (N = 5946), based on representative national samples living in private households. We used probabilistic graphical models represented by directed acyclic graphs (DAGs). We obtained measures of persecutory ideation and auditory hallucinosis from the Psychosis Screening Questionnaire, and identified affective symptoms using the Clinical Interview Schedule. We included cannabis consumption and sex as they may determine the relationship between symptoms. We constrained incoming edges to sexual abuse and bullying to respect temporality. RESULTS:In the DAG analyses, contrary to our expectations, paranoia appeared early in the cascade of relationships, close to the abuse variables, and generally lying upstream of affective symptoms. Paranoia was consistently directly antecedent to hallucinations, but also indirectly so, via non-psychotic symptoms. Hallucinosis was also the endpoint of pathways involving non-psychotic symptoms. CONCLUSIONS:Via worry, sexual abuse and bullying appear to drive a range of affective symptoms, and in some people, these may encourage the emergence of hallucinations. The link between adverse experiences and paranoia is much more direct. These findings have implications for managing distressing outcomes. In particular, worry may be a salient target for intervention in psychosis.

INTRODUCTION:Violence perpetration by adults with severe mental illness (SMI) specifically towards their relatives is a sensitive topic and a largely neglected area that has consequences and implications for different stakeholders, including healthcare providers. This paper sought to systematically review the relevant literature, to identify the types and rates of violence by people with SMI against their relatives, and to develop a detailed understanding of its reported impacts. METHODS:A systematic review, registered with PROSPERO (registration number CRD42019150784), was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The review comprised searches of Medline, Embase, PsycInfo and CINAHL databases, supplemented by manual searches. Data from 38 papers using mixed methodologies were reviewed. RESULTS:Key findings highlighted that relatives experienced different types of violence, including physical, verbal, psychological, financial violence, and violence directed towards property. Different types often co-occurred. Mothers were the group most likely to report being victims, compared with other relatives. Reported impacts of violence on relatives included mental ill health (e.g., psychological distress, post-traumatic stress symptoms) and the deterioration, and in some cases the permanent breakdown, of family relationships and the family unit. However, relatives often continued to provide a framework of support for patients, despite risks to their own safety. CONCLUSION:Findings speak to the importance of future research extending the focus beyond the identified victimised relative or perpetrator, to also consider the impacts of violence at the family-wide level, and to improve the outcomes of families exposed to and dealing with violence by individuals living with SMI.

Background Marginalized groups are more likely to experience problems with technology-related access, motivation, and skills. This is known as the “digital divide.” Technology-related exclusion is a potential barrier to the equitable implementation of digital health. SlowMo therapy was developed with an inclusive, human-centered design to optimize accessibility and bridge the “digital divide.” SlowMo is an effective, blended digital psychological therapy for paranoia in psychosis. Objective This study explores the “digital divide” and mobile app engagement in the SlowMo randomized controlled trial. Methods Digital literacy was assessed at baseline, and a multidimensional assessment of engagement (ie, adherence [via system analytics and self-report] and self-reported user experience) was conducted at 12 weeks after therapy. Engagement was investigated in relation to demographics (ie, gender, age, ethnicity, and paranoia severity). Results Digital literacy data demonstrated that technology use and confidence were lower in Black people and older people (n=168). The engagement findings indicated that 80.7% (96/119) of therapy completers met the a priori analytics adherence criteria. However, analytics adherence did not differ by demographics. High rates of user experience were reported overall (overall score: mean 75%, SD 17.1%; n=82). No differences in user experience were found for ethnicity, age, or paranoia severity, although self-reported app use, enjoyment, and usefulness were higher in women than in men. Conclusions This study identified technology-related inequalities related to age and ethnicity, which did not influence engagement with SlowMo, suggesting that the therapy design bridged the “digital divide.” Intervention design may moderate the influence of individual differences on engagement. We recommend the adoption of inclusive, human-centered design to reduce the impact of the “digital divide” on therapy outcomes.

AbstractObjectivesSlowMo therapy is a pioneering blended digital therapy for paranoia, augmenting face‐to‐face therapy with an interactive ‘webapp’ and a mobile app. A recent large‐scale trial demonstrated small–moderate effects on paranoia alongside improvements in self‐esteem, worry, well‐being and quality of life. This paper provides a comprehensive account of therapy personalisation within this targeted approach.DesignCase examples illustrate therapy delivery and descriptive data are presented on personalised thought content.MethodThought content was extracted from the webapp (n = 140 participants) and coded using newly devised categories: Worries: (1) Persecutory, (2) Negative social evaluation, (3) Negative self‐concept, (4) Loss/life stresses, (5) Sensory‐perceptual experiences and (6) Health anxieties. Safer thoughts: (1) Safer alternative (specific alternatives to worries), (2) Second‐wave (generalised) coping, (3) Positive self‐concept, (4) Positive activities and (5) Third‐wave (mindfulness‐based) coping. Data on therapy fidelity are also presented.ResultsWorries: ‘Persecutory’ (92.9% of people) and ‘Negative social evaluation’ (74.3%) were most common. ‘General worries/ life stresses’ (31.4%) and ‘Negative self‐concept’ (22.1%) were present in a significant minority; ‘Health anxieties’ (10%) and ‘Sensory‐perceptual’ (10%) were less common. Safer thoughts: ‘Second‐wave (general) coping’ (85%), ‘Safer alternatives’ (76.4%), ‘Positive self‐concept’ (65.7%) and ‘Positive activities’ (64.3%) were common with ‘Third‐wave’ (mindfulness) coping observed for 30%. Fidelity: Only three therapy withdrawals were therapy related. Session adherence was excellent (mean = 15.2/16; SD = 0.9). Behavioural work was conducted with 71% of people (119/168).ConclusionSlowMo therapy delivers a targeted yet personalised approach. Potential mechanisms of action extend beyond reasoning. Implications for cognitive models of paranoia and causal interventionist approaches are discussed.

Abstract Background People with psychosis have high rates of trauma, with a post-traumatic stress disorder (PTSD) prevalence rate of approximately 15%, which exacerbates psychotic symptoms such as delusions and hallucinations. Pilot studies have shown that trauma-focused (TF) psychological therapies can be safe and effective in such individuals. This trial, the largest to date, will evaluate the clinical effectiveness of a TF therapy integrated with cognitive behaviour therapy for psychosis (TF-CBTp) on post-traumatic stress symptoms in people with psychosis. The secondary aims are to compare groups on cost-effectiveness; ascertain whether TF-CBTp impacts on a range of other meaningful outcomes; determine whether therapy effects endure; and determine acceptability of the therapy in participants and therapists. Methods Rater-blind, parallel arm, pragmatic randomised controlled trial comparing TF-CBTp + treatment as usual (TAU) to TAU only. Adults (N = 300) with distressing post-traumatic stress and psychosis symptoms from five mental health Trusts (60 per site) will be randomised to the two groups. Therapy will be manualised, lasting 9 months (m) with trained therapists. We will assess PTSD symptom severity (primary outcome); percentage who show loss of PTSD diagnosis and clinically significant change; psychosis symptoms; emotional well-being; substance use; suicidal ideation; psychological recovery; social functioning; health-related quality of life; service use, a total of four times: before randomisation; 4 m (mid-therapy); 9 m (end of therapy; primary end point); 24 m (15 m after end of therapy) post-randomisation. Four 3-monthly phone calls will be made between 9 m and 24 m assessment points, to collect service use over the previous 3 months. Therapy acceptability will be assessed through qualitative interviews with participants (N = 35) and therapists (N = 5–10). An internal pilot will ensure integrity of trial recruitment and outcome data, as well as therapy protocol safety and adherence. Data will be analysed following intention-to-treat principles using generalised linear mixed models and reported according to Consolidated Standards of Reporting Trials-Social and Psychological Interventions Statement. Discussion The proposed intervention has the potential to provide significant patient benefit in terms of reductions in distressing symptoms of post-traumatic stress, psychosis, and emotional problems; enable clinicians to implement trauma-focused therapy confidently in this population; and be cost-effective compared to TAU through reduced service use.

Informal caregivers of individuals affected by psychotic disorder can play a key role in the recovery process. However, little research has been conducted on the lived experiences of carers and family members. We conducted a bottom-up (from lived experience to theory) review of first-person accounts, co-written between academics and experts by experience, to identify key experiential themes. First-person accounts of carers, relatives, and individuals with psychosis were screened and discussed in collaborative workshops involving individuals with lived experiences of psychosis, family members, and carers, representing various organizations. The lived experiences of family members and carers were characterized by experiential themes related to dealing with the unexpected news, the search for a reason behind the disorder, living with difficult and negative emotions, dealing with loss, feeling lost in fragmented healthcare systems, feeling invisible and wanting to be active partners in care, struggling to communicate with the affected person, fighting stigma and isolation, dealing with an uncertain future, and learning from one’s mistakes and building resilience and hope. Our findings bring forth the voices of relatives and informal carers of people with psychosis, by highlighting some of the common themes of their lived experiences from the time of the initial diagnosis and throughout the different clinical stages of the disorder. Informal carers are key stakeholders who can play a strategic role, and their contributions in the recovery process merit recognition and active support by mental health professionals.

Introduction Compared to the general population, people living with schizophrenia spectrum disorders (SSD) are more likely to perpetrate acts of violence. When this happens, family members (informal carers) are most commonly the victims. However, family violence by people with SSD is often a taboo topic and largely neglected within public discourse, research, and clinical domains. Consequently, our understanding of families’ experiences and support needs are limited. Objectives To develop a detailed understanding of the subjective experiences, and impact, of patient violence towards family carers. Methods Individual semi-structured interviews were held with family carers of adults with SSD and a history of violence perpetration towards their family carer. Interview data were subject to thematic analyses using NVivo software. Results Twenty-one UK based carers that were predominately White British (90%) and female (81%) were interviewed. Key themes highlight the range of physical and mental injuries endured by carers following patient violence, and speak to carers’ experiences of suffering, living in a constant state of hypervigilance, as well as social isolation in the context of shame, stigma, and an absence of professional and informal support. Conclusions Family violence by people living with SSD can and does happen. Yet, too often, carers are left with no option but to continue supporting their relative in the absence of support, even in contexts where this compromises their own safety. The devastating impact of violence is far-reaching, across all levels of the family-system. The findings highlight the danger of neglecting family violence by people with SSD in research and clinical fields. Disclosure No significant relationships.

Abstract Objectives SlowMo is the first blended digital therapy for paranoia, showing significant small‐moderate reductions in paranoia in a recent large‐scale randomized controlled trial (RCT). This study explored the subjective service‐user experience of the SlowMo therapy content and design; the experience of the blended therapy approach, including the triangle of the therapeutic alliance; and the experience of the digital aspects of the intervention. Design Qualitative co‐produced sub‐study of an RCT. Methods Participants were 22 adult service users with schizophrenia‐spectrum psychosis and persistent distressing paranoia, who completed at least one SlowMo therapy session and a 24‐week follow‐up, at one of 3 sites in Oxford, London, and Sussex, UK. They were interviewed by peer researchers, using a topic guide co‐produced by the Patient and Public Involvement (PPI) team. The transcribed data were analysed thematically. Multiple coding and triangulation, and lay peer researcher validation were used to reach a consensus on the final theme structure. Results Six core themes were identified: (i) starting the SlowMo journey; (ii) the central role of the supportive therapist; (iii) slowing things down; (iv) value and learning from social connections; (v) approaches and challenges of technology; and (vi) improvements in paranoia and well‐being. Conclusions For these service users, slowing down for a moment was helpful, and integrated into thinking over time. Learning from social connections reflected reduced isolation, and enhanced learning through videos, vignettes, and peers. The central role of the supportive therapist and the triangle of alliance between service user, therapist, and digital platform were effective in promoting positive therapeutic outcomes.

On 11th March 2020, the World Health Organisation (WHO) announced that the COVID-19 virus was a pandemic. Subsequently, a wave of dedicated measures was implemented by countries around the world in an effort to slow its spread. Closure of schools and universities, remote working, travel restrictions, home confinement and ‘social’ (i.e. physical) distancing were among the key preventative measures that were adopted within the United Kingdom (UK) and many other countries. Mounting concern about how the pandemic, and the corresponding public health measures, might affect the mental health of the general population, prompted rapid research into the potential effects of COVID-19 on mental health. In the UK general population, evidence covering the period from October 2019 to April 2020 suggests that, when compared to data from the final quarter of 2019, adults have reported significantly greater levels of anxiety and lower levels of positive mental wellbeing in the first quarter of 2020 (ONS, 2020). Evidence further suggests that the largest deterioration can be observed in clinical populations; those with the poorest mental health prior to the pandemic (Xu & Banks, 2020). However, compared to the general population, the needs of clinical populations such as those with severe mental illness (SMI) have received less attention (The Lancet Psychiatry, 2020). Since COVID-19 and the measures introduced to slow its spread have been shown to be associated with higher stress and an observable deterioration in the mental health of the general population (Xu & Banks, 2020), it is possible that these effects are likely to be even greater or more challenging in populations with SMI.

Background Reasoning may play a causal role in paranoid delusions in psychosis. SlowMo, a new digitally supported cognitive–behavioural therapy, targets reasoning to reduce paranoia. Objectives To examine the effectiveness of SlowMo therapy in reducing paranoia and in improving reasoning, quality of life and well-being, and to examine its mechanisms of action, moderators of effects and acceptability. Design A parallel-arm, assessor-blind, randomised controlled trial comparing SlowMo plus treatment as usual with treatment as usual alone. An online independent system randomised eligible participants (1 : 1) using randomly varying permuted blocks, stratified by site and paranoia severity. Setting Community mental health services in three NHS mental health trusts in England, plus patient identification centres. Participants A total of 362 participants with schizophrenia-spectrum psychosis. Eligibility criteria comprised distressing and persistent (≥ 3 months) paranoia. Interventions Eight face-to-face SlowMo sessions over 12 weeks plus treatment as usual, or treatment as usual alone (control group). Main outcome measures The primary outcome measure was paranoia measured by the Green Paranoid Thoughts Scale and its revised version, together with observer-rated measures of persecutory delusions (The Psychotic Symptom Rating Scales delusion scale and delusion items from the Scale for the Assessment of Positive Symptoms). The secondary outcome measures were reasoning (measures of belief flexibility, jumping to conclusions, and fast and slow thinking), well-being, quality of life, schemas, service use and worry. Results A total of 362 participants were recruited between 1 May 2017 and 14 May 2019: 181 in the SlowMo intervention group and 181 in the treatment-as-usual (control) group. One control participant subsequently withdrew. In total, 325 (90%) participants provided primary Green Paranoid Thoughts Scale outcome data at 12 weeks (SlowMo, n = 162; treatment as usual, n = 163). A total of 145 (80%) participants in the SlowMo group completed all eight therapy sessions. SlowMo was superior to treatment as usual in reducing paranoia on all three measures used: Green Paranoid Thoughts Scale total at 12 weeks (Cohen’s d = 0.30, 95% confidence interval 0.09 to 0.51; p = 0.005) and 24 weeks (Cohen’s d = 0.20, 95% confidence interval –0.02 to 0.40; p = 0.063); Psychotic Symptom Rating Scales delusions at 12 weeks (Cohen’s d = 0.47, 95% confidence interval 0.17 to 0.78; p = 0.002) and 24 weeks (Cohen’s d = 0.50, 95% confidence interval 0.20 to 0.80; p = 0.001); and Scale for the Assessment of Positive Symptoms persecutory delusions at 12 weeks (Cohen’s d = 0.43, 95% confidence interval 0.03 to 0.84; p = 0.035) and 24 weeks (Cohen’s d = 0.54, 95% confidence interval 0.14 to 0.94; p = 0.009). Reasoning (belief flexibility, possibility of being mistaken and Fast and Slow Thinking Questionnaire measure) improved, but jumping to conclusions did not improve. Worry, quality of life, well-being and self-concept also improved, improving most strongly at 24 weeks. Baseline characteristics did not moderate treatment effects. Changes in belief flexibility and worry mediated changes in paranoia. Peer researcher-led qualitative interviews confirmed positive experiences of the therapy and technology. Nineteen participants in the SlowMo group and 21 participants in the treatment-as-usual group reported 54 adverse events (51 serious events, no deaths). Limitations The trial included treatment as usual as the comparator and, thus, the trial design did not control for the effects of time with a therapist. Conclusions To the best of our knowledge, this is the largest trial of a psychological therapy for paranoia in people with psychosis and the first trial using a brief targeted digitally supported therapy. High rates of therapy uptake demonstrated acceptability. It was effective for paranoia, comparable to longer therapy, and equally effective for people with different levels of negative symptoms and working memory. Mediators were improvements in belief flexibility and worry. Our results suggest that targeting reasoning helps paranoia.

Background Informal (unpaid) carers represent a core component of health and social care systems. However, their experiences, health impacts and care needs during Covid-19 have been largely overlooked. This study aimed to explore the health and wellbeing impacts of Covid-19 on carers and the contribution of hopefulness.Methods Data were collected from an online survey hosted on the Qualtrics platform.Results Three hundred and sixty-nine participants consented to the survey. Data are reported on 186 participants with an 80% or higher completion rate. Most participants (> 80%) reported poor sleep quality, while nearly half the sample met case threshold for anxiety (46.2%) and 29% for depression. Mood disturbance in carers was associated with higher levels of sleep disturbances. Positive wellbeing in carers was best predicted by having a more hopeful outlook and fewer symptoms of depression.Limitations A cross-sectional survey-based design that is unable to offer no definitive conclusions about the direction of the results. The study was also limited by having carer participants as the only informants.Conclusions Though informal carers are found in all areas of society, their experiences and health correlates during Covid-19 have not attracted much research attention. The additional and unique challenges of the pandemic for the health and wellbeing needs of carers must not be overlooked as is sadly so often the case. Instead, the experiences of carers and their needs should be prioritised, publicised, and matched by needs-led interventions. Identifying carers and enquiring about their wellbeing would be a laudable first step.

Neurocognitive difficulties and early childhood speech/motor delays are well documented amongst older adolescents and young adults considered at risk for psychosis-spectrum diagnoses. We aimed to test associations between unusual or psychotic-like experiences (PLEs), co-occurring distress/emotional symptoms, current cognitive functioning and developmental delays/difficulties in young people (aged 8–18 years) referred to Child and Adolescent Mental Health Services in South London, UK. Study 1 examined receptive language, verbal learning and caregiver-reported speech and motor delays/difficulties in a sample of 101 clinically-referred children aged 8–14 years, comparing those reporting no PLEs (n = 19), PLEs without distress (n = 16), and PLEs with distress (n = 66). Study 2 tested associations of severity of distressing PLEs with vocabulary, perceptual reasoning, word reading and developmental delays/difficulties in a second sample of 122 adolescents aged 12–18 years with distressing PLEs. In Study 1, children with distressing PLEs had lower receptive language and delayed recall and higher rates of developmental delays/difficulties than the no-PLE and non-distressing PLE groups (F values: 2.3–2.8; p values: < 0.005). Receptive language (β = 0.24, p = 0.03) and delayed recall (β = − 0.17, p = 0.02) predicted PLE distress severity. In Study 2, the cognitive-developmental variables did not significantly predict PLE distress severity (β values = 0.01–0.22, p values: > 0.05). Findings may be consistent with a cognitive-developmental model relating distressing PLEs in youth with difficulties in cognitive functioning. This highlights the potential utility of adjunctive cognitive strategies which target mechanisms associated with PLE distress. These could be included in cognitive-behavioural interventions offered prior to the development of an at-risk mental state in mental health, educational or public health settings.

BACKGROUND SlowMo is a digitally supported therapy for paranoia that was developed using inclusive, human-centred design to improve outcomes and address barriers to implementation. SlowMo significantly improved paranoia and wellbeing compared to treatment as usual in a recent randomised controlled trial of 362 people with psychosis. OBJECTIVE This study evaluates whether the design was effective in optimising the user experience of the SlowMo mobile app for a diverse range of people. METHODS Digital literacy, adherence (via system analytics and self-report) and user experience were assessed, and investigated in relation to demographics (i.e. gender, age, ethnicity, paranoia severity). RESULTS 81% of therapy completers met the a priori analytics adherence criteria. Technology use and confidence was lower in Black people and older people. However, analytics adherence did not differ by demographics. High rates of user experience were reported overall (75%, SD = 17.06), although self-reported app use, enjoyment and usefulness were higher in women than men. No differences were found for ethnicity, age or paranoia severity. CONCLUSIONS The SlowMo therapy design overcame the ‘digital divide’ in the user experience of psychosis therapies, validating the importance of employing human-centred design when developing therapeutics. SlowMo may address implementation barriers for minoritised groups of people with psychosis. It should be further developed and tested in the NHS. CLINICALTRIAL ISRCTN32448671

Informal (unpaid) carers are an integral part of all societies and the health and social care systems in the UK depend on them. Despite the valuable contributions and key worker status of informal carers, their lived experiences, wellbeing, and needs have been neglected during the COVID-19 pandemic. In this Health Policy, we bring together a broad range of clinicians, researchers, and people with lived experience as informal carers to share their thoughts on the impact of the COVID-19 pandemic on UK carers, many of whom have felt abandoned as services closed. We focus on the carers of children and young people and adults and older adults with mental health diagnoses, and carers of people with intellectual disability or neurodevelopmental conditions across different care settings over the lifespan. We provide policy recommendations with the aim of improving outcomes for all carers.

Key Points Question Can a brief blended digital therapy targeting reasoning (SlowMo) improve paranoia for adults with psychosis when added to usual care? Findings This randomized clinical trial of 361 individuals with clinical paranoia did not demonstrate that SlowMo therapy reduced the primary outcome of self-reported paranoia at 24 weeks compared with usual care only, although secondary beneficial effects were found on this measure at 12 weeks. Self-reported persecution and observer-rated paranoia were improved at both points. Meaning SlowMo, a digitally supported reasoning intervention, indicated a beneficial effect on paranoia; further work to optimize the effects of SlowMo is warranted.

The original CHoice of Outcome In Cbt for psychosEs (CHOICE) measure was designed in collaboration with experts by experience as a patient-reported "Psychological Recovery" outcome measure for cognitive-behavioral therapy for psychosis (CBTp). A short version (CHOICE-SF) was developed to use as a brief outcome measure, with a focus on sensitivity to change, for use in future research and practice. CHOICE-SF was developed and validated using 3 separate samples, comprising 640 service users attending 1 of 2 transdiagnostic clinics for (1) CBTp or (2) therapies for voice hearing or (3) who took part in the treatment as usual arm of a trial. In the initial subsample of 69 participants, items from the original CHOICE measure with medium to large effect sizes for change pre- to post-CBTp were retained to form the CHOICE-SF. Internal consistency, construct validity, and sensitivity to change were confirmed, and the factor structure was examined in 242 participants. Specificity was confirmed by comparison with 44 participants who completed CHOICE at 2 time points but did not receive therapy. Validation of CHOICE-SF was carried out by confirming factor structure and sensitivity to change in a new sample of 354 and a subsample of 51 participants, respectively. The CHOICE-SF comprised 11 items and 1 additional personal goal item. A single-factor structure was confirmed, with high internal consistency, construct validity, and sensitivity to change. The CHOICE-SF is a brief, psychometrically robust measure to assess change following psychological therapies in research and clinical practice for people with psychosis and severe mental illness.
