RESUMEN

Hallucinations are a common feature of psychosis, yet access to effective psychological treatment is limited. The Managing Unusual Sensory Experiences for First-Episode-Psychosis (MUSE-FEP) trial aimed to establish the feasibility and acceptability of a brief, hallucination-specific, digitally provided treatment, delivered by a non-specialist workforce for people with psychosis. MUSE uses psychoeducation about the causal mechanisms of hallucinations and tailored interventions to help a person understand and manage their experiences. We undertook a two-site, single-blind (rater) Randomised Controlled Trial and recruited 82 participants who were allocated 1:1 to MUSE and treatment as usual (TAU) (n = 40) or TAU alone (n = 42). Participants completed assessments before and after treatment (2 months), and at follow up (3-4 months). Information on recruitment rates, adherence, and completion of outcome assessments was collected. Analyses focussed on feasibility outcomes and initial estimates of intervention effects to inform a future trial. The trial is registered with the ISRCTN registry 16793301. Criteria for the feasibility of trial methodology and intervention delivery were met. The trial exceeded the recruitment target, had high retention rates (87.8%) at end of treatment, and at follow up (86.6%), with good acceptability of treatment. There were 3 serious adverse events in the therapy group, and 5 in the TAU group. Improvements were evident in both groups at the end of treatment and follow up, with a particular benefit in perceived recovery in the MUSE group. We showed it was feasible to increase access to psychological intervention but a definitive trial requires further changes to the trial design or treatment.

RESUMEN

BACKGROUND: The National Institute for Health and Care Excellence (NICE) recommends that cognitive behaviour therapy (CBT) is offered to all patients with a psychosis diagnosis. However, only a minority of psychosis patients in England and Wales are offered CBT. This is attributable, in part, to the resource-intensive nature of CBT. One response to this problem has been the development of CBT in brief formats that are targeted at a single symptom and are deliverable by briefly trained therapists. We have developed Guided self-help CBT (the GiVE intervention) as a brief form of CBT for distressing voices and reported evidence for the feasibility of a randomised controlled trial (RCT) when the intervention was delivered by briefly trained therapists (assistant psychologists). This study will investigate the clinical and cost-effectiveness of the GiVE intervention when delivered by assistant psychologists following a brief training. METHODS: This study is a pragmatic, two-arm, parallel group, superiority RCT comparing the GiVE intervention (delivered by assistant psychologists) and treatment as usual to treatment as usual alone, recruiting across three sites, using 1:1 allocation and blind post-treatment and follow-up assessments. A nested qualitative study will develop a model for implementation. DISCUSSION: If the GiVE intervention is found to be effective when delivered by assistant psychologists, this intervention could significantly contribute to increasing access to evidence-based psychological interventions for psychosis patients. Furthermore, implementation across secondary care services within the UK's National Health Service may pave the way for other symptom-specific and less resource-intensive CBT-informed interventions for psychosis patients to be developed and evaluated. TRIAL REGISTRATION: Current Controlled Trials ISRCTN registration number: 12748453. Registered on 28 September 2022.

RESUMEN

INTRODUCTION: Individuals who access at-risk mental state (ARMS) services often have unusual sensory experiences and levels of distress that lead them to seek help. The Managing Unusual Sensory Experiences (MUSE) treatment is a brief symptom targeted intervention that draws on psychological explanations to help account for unusual experiences. Practitioners use formulation and behavioural experiments to support individuals to make sense of their experiences and enhance coping strategies. The primary objective of this feasibility trial is to resolve key uncertainties before a definitive trial and inform parameters of a future fully powered trial. METHODS AND ANALYSIS: 88 participants aged 14-35 accepted into ARMS services, experiencing hallucinations/unusual sensory experiences which are considered by the patient to be a key target problem will be recruited from UK National Health Service (NHS) sites and randomised using 1:1 allocation (stratified by site, gender, and age) to either 6-8 sessions of MUSE or time-matched treatment as usual. Participants and therapists will be unblinded, research assessors are blinded. Blinded assessment will occur at baseline, 12 weeks and 20 weeks postrandomisation. Data will be reported in line with Consolidated Standards of Reporting Trials. Primary trial outcomes are feasibility outcomes, primary participant outcomes are functioning and hallucinations. Additional analysis will investigate potential psychological mechanisms and secondary mental well-being outcomes. Trial progression criteria follows signal of efficacy and uses an analytical framework with a traffic-light system to determine viability of a future trial. Subsequent analysis of the NHS England Mental Health Services Data Set 3 years postrandomisation will assess long-term transition to psychosis. ETHICS AND DISSEMINATION: This trial has received Research Ethics Committee approval (Newcastle North Tyneside 1 REC; 23/NE/0032). Participants provide written informed consent; young people provide assent with parental consent. Dissemination will be to ARMS Services, participants, public and patient forums, peer-reviewed publications and conferences. TRIAL REGISTRATION NUMBER: ISRCTN58558617.

RESUMEN

Hallucinations can occur in single or multiple sensory modalities. Greater attention has been paid to single sensory experiences with a comparative neglect of hallucinations that occur across two or more sensory modalities (multisensory hallucinations). This study explored how common these experiences were in people at risk of transition to psychosis (n=105) and considered whether a greater number of hallucinatory experiences increased delusional ideation and reduced functioning, both of which are associated with a greater risk of transition to psychosis. Participants reported a range of unusual sensory experiences, with two or three being common. However, when a strict definition of hallucinations was applied, in which the experience has the quality of a real perception and in which the person believes them to be real experiences, then multisensory experiences were rare and when reported, single sensory hallucinations in the auditory domain were most common. The number of unusual sensory experiences or hallucinations was not significantly associated with greater delusional ideation or poorer functioning. Theoretical and clinical implications are discussed.

RESUMEN

Hallucinations can occur in single or multiple sensory modalities. This study explored how common these experiences were in people with first episode of psychosis (n = 82). Particular attention was paid to the number of modalities reported and whether the experiences were seen to be linked temporally and thematically. It was predicted that those people reporting a greater number of hallucinations would report more delusional ideation, greater levels of distress generally and lower functioning. All participants reported hallucinations in the auditory domain, given the nature of the recruitment. The participants also reported a range of other unusual sensory experiences, with visual and tactile hallucinations being reported by over half. Moreover, single sensory experiences or unimodal hallucinations were less common than two or more hallucination modalities which was reported by 78% of the participants. The number of hallucinations was significantly associated with greater delusional ideation and higher levels of general distress, but not with reduced functioning. It is clear there is a need to refine psychological treatments so that they are better matched to the actual experiences reported by people with psychosis. Theoretical implications are also considered.

RESUMEN

Auditory verbal hallucinations (AVHs) are typically associated with schizophrenia but also occur in individuals without any need for care (nonclinical voice hearers [NCVHs]). Cognitive models of AVHs posit potential biases in source monitoring, top-down processes, or a failure to inhibit intrusive memories. However, research across clinical/nonclinical groups is limited, and the extent to which there may be continuity in cognitive mechanism across groups, as predicted by the psychosis-continuum hypothesis, is unclear. We report two studies in which voice hearers with psychosis (n = 31) and NCVH participants reporting regular spiritual voices (n = 26) completed a battery of cognitive tasks. Compared with non-voice-hearing groups (ns = 33 and 28), voice hearers with psychosis showed atypical performance on signal detection, dichotic listening, and memory-inhibition tasks but intact performance on the source-monitoring task. NCVH participants, however, showed only atypical signal detection, which suggests differences between clinical and nonclinical voice hearers potentially related to attentional control and inhibition. These findings suggest that at the level of cognition, continuum models of hallucinations may need to take into account continuity but also discontinuity between clinical and nonclinical groups.

RESUMEN

INTRODUCTION: Hallucinations (hearing or seeing things that others do not) are a common feature of psychosis, causing significant distress and disability. Existing treatments such as cognitive-behavioural therapy for psychosis (CBTp) have modest benefits, and there is a lack of CBTp-trained staff. Shorter, targeted treatments that focus on specific symptoms delivered by a non-specialist workforce could substantially increase access to treatment.Managing Unusual Sensory Experiences (MUSE) explains why people have hallucinations and helps the person to develop and use coping strategies to reduce distress. MUSE focuses only on hallucinations, and treatment is short (four to six, 1-hour sessions per week). It is a digital intervention, run on National Health Service (NHS) laptops, which provides information about hallucinations in an engaging way, using audio, video and animated content. Crucially, it is designed for use by non-specialist staff like community psychiatric nurses. METHODS AND ANALYSIS: The study is a two-arm feasibility randomised controlled trial comparing MUSE and treatment as usual (TAU) (n=40) to TAU alone (n=40), recruiting across two NHS Trusts, using 1:1 allocation and blind assessments before and after treatment (2 months) and at follow-up (3 months). Quantitative information on recruitment rates, adherence and completion of outcome assessments will be collected. Qualitative interviews will capture service users' experience of therapy and clinicians' experiences of the training and supervision in MUSE. Clinicians will also be asked about factors affecting uptake, adherence and facilitators/barriers to implementation. Analyses will focus on feasibility outcomes and provide initial estimates of intervention effects. Thematic analysis of the qualitative interviews will assess the acceptability of the training, intervention and trial procedures. ETHICS AND DISSEMINATION: The trial has received NHS Ethical and Health Research Authority approval. Findings will be disseminated directly to participants and services, as well as through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: ISRCTN16793301.

RESUMEN

OBJECTIVES: Making sense of voice-hearing-exploring the purpose, cause, and relationship with voices-is seen as therapeutically valuable for adults, but there is a paucity of research with adolescents. Family intervention is recommended for young people, yet little is known about families' perspectives on, or role in, a child's voice-hearing. This study therefore aimed to explore how both young people and parents had made sense of voice-hearing in the family context. METHOD: Semi-structured interviews were conducted with seven young people who hear voices (six females, one male, age M = 17 years) and six parents of young people who hear voices (five females, one male). Data were analysed using interpretative phenomenological analysis. RESULTS: The young people struggled to reconcile their voice-hearing experiences within themselves, wanted control, 'normality', and not to let their mental health hold them back. Parents saw the voices as separate to their child, who they were protective of, and came to an acceptance and hope for the future amidst continued uncertainty. Pragmatism, and shame, ran through parents' and young people's accounts. Tensions between them, such as autonomy versus involvement, were also apparent. CONCLUSIONS: Few participants had made sense of their experiences in any concrete form, yet hope, control, and getting on with their lives were not conditional on having done so. Young people valued the family as a safe, non-enquiring space to be 'normal' and not to talk about their experiences. While all had been challenged by their experiences, an energy and strength ran through their accounts.

RESUMEN

BACKGROUND: Bipolar disorder is a chronic mental health condition, which can result in functional impairment despite medication. A large evidence base supports use of psychological therapies and structured care in the treatment of mood disorders, but these are rarely implemented. e-Pathways are digital structures that inform and record patient progress through a healthcare system, although these have not yet been used for bipolar disorder. AIMS: To assess the perceived benefits and costs associated with implementing a collaborative NICE-informed e-pathway for bipolar disorder. METHOD: Healthcare professionals and people with bipolar disorder attended a workshop to share feedback on e-pathways. Data were collected through questionnaires (n = 26) and transcription of a focus group, analysed qualitatively by a framework analysis. RESULTS: Patients and healthcare professionals welcomed the development of an e-pathway for bipolar disorder. There were five elements to the framework: quality and delivery of care, patient-clinician collaboration, flexibility and adaptability, impact on staff and impact on healthcare services. CONCLUSIONS: Identification of benefits and costs ensures that future development of e-pathways addresses concerns of healthcare professionals and people with bipolar disorder, which would be essential for successful implementation. Recommendations for this development include making e-pathways less complicated for patients, ensuring sufficient training and ensuring clinicians do not feel their skills become invalidated. Limitations of the study, and directions for future research, are discussed.

RESUMEN

Recent therapeutic approaches to auditory verbal hallucinations (AVH) exploit the person-like qualities of voices. Little is known, however, about how, why, and when AVH become personified. We aimed to investigate personification in individuals' early voice-hearing experiences. We invited Early Intervention in Psychosis (EIP) service users aged 16-65 to participate in a semistructured interview on AVH phenomenology. Forty voice-hearers (M = 114.13 days in EIP) were recruited through 2 National Health Service trusts in northern England. We used content and thematic analysis to code the interviews and then statistically examined key associations with personification. Some participants had heard voices intermittently for multiple years prior to clinical involvement (M = 74.38 months), although distressing voice onset was typically more recent (median = 12 months). Participants reported a range of negative emotions (predominantly fear, 60%, 24/40, and anxiety, 62.5%, 26/40), visual hallucinations (75%, 30/40), bodily states (65%, 25/40), and "felt presences" (52.5%, 21/40) in relation to voices. Complex personification, reported by a sizeable minority (16/40, 40%), was associated with experiencing voices as conversational (odds ratio [OR] = 2.56) and companionable (OR = 3.19) but not as commanding or trauma-related. Neither age of AVH onset nor time since onset related to personification. Our findings highlight significant personification of AVH even at first clinical presentation. Personified voices appear to be distinguished less by their intrinsic properties, commanding qualities, or connection with trauma than by their affordances for conversation and companionship.

RESUMEN

OBJECTIVES: To conduct a feasibility study on a new, tablet-delivered treatment for unusual sensory experiences in service-users with an At Risk Mental States for psychosis. DESIGN: A mixed method design was employed, using content analysis to investigate whether service-users and therapists found the new treatment acceptable and helpful. We also collected data on the impact of treatment, but without a control group could not make any claims about effectiveness. METHODS: Eligible participants were contacted before starting treatment and offered the chance to participate. Assessments were conducted before and after the treatment, which typically was completed in 4-6 sessions by an accredited CBT therapist. A structured interview was used to collect qualitative feedback. RESULTS: Qualitative feedback suggested that the treatment was acceptable to service-users and therapists, and the progression criteria were met for recruitment, retention, and adherence to treatment. CONCLUSIONS: The new treatment targeting subtypes of auditory and visual hallucinations was acceptable to service-users and the benefits of addressing psychological mechanisms thought to contribute to hallucinations was supported by qualitative feedback. PRACTITIONER POINTS: A novel treatment has been developed for unusual sensory experiences based on subtyping voices and using technology to help explain psychological mechanisms that may be linked to hallucinations. The treatment was acceptable to service users and therapists in At Risk Mental States for psychosis services with qualitative feedback supporting the approach. The treatment may be particularly useful in preventing the progressions of psychosis as people who have not developed fixed ideas about the origin of the experiences may be more open to alternative explanations.

RESUMEN

BACKGROUND: Cognitive behavioural therapy for psychosis (CBTp) is a recommended treatment for psychotic experiences, but its effectiveness has been questioned. One way of addressing this may be to tailor therapy materials to the phenomenology of specific psychotic experiences. AIM: In this study, we investigated the acceptability of a novel treatment manual for subtypes of 'voice-hearing' experiences (i.e. auditory verbal hallucinations). An uncontrolled, single-arm design was used to assess feasibility and acceptability of using the manual in routine care for people with frequent voice-hearing experiences. METHOD: The manual was delivered on a smart tablet and incorporated recent research evidence and theory into its psychoeducation materials. In total, 24 participants completed a baseline assessment; 19 started treatment, 15 completed treatment and 12 participants completed a follow-up assessment (after 10 sessions of using the manual). RESULTS: Satisfaction with therapy scores and acceptability ratings were high, while completion rates suggested that the manual may be more appropriate for help with participants from Early Intervention in Psychosis services rather than Community Mental Health Teams. CONCLUSION: Within-group changes in symptom scores suggested that overall symptom severity of hallucinations - but not other psychosis features, or beliefs about voices - are likely to be the most appropriate primary outcome for further evaluation in a full randomised controlled trial.

RESUMEN

A recently popular framework in the cognitive sciences takes the human nervous system to be a hierarchically arranged Bayesian prediction machine. In this paper, we examine psychological trauma through the lens of this framework. We suggest that this can help us to understand the nature of trauma, and the different effects that different kinds of trauma can have. We end by exploring synergies between our approach and current theories of PTSD, and gesture toward future directions.

RESUMEN

Cognitive behavioral therapy (CBT) for voice-hearing (i.e., auditory verbal hallucinations; AVH) has, at best, small to moderate effects. One possible reason for this limited efficacy is that current CBT approaches tend to conceptualize voice-hearing as a homogenous experience in terms of the cognitive processes involved in AVH. However, the highly heterogeneous nature of voice-hearing suggests that many different cognitive processes may be involved in the etiology of AVH. These heterogeneous voice-hearing experiences do, however, appear to cluster into a set of subtypes, opening up the possibility of tailoring treatment to the subtype of AVH that a voice-hearer reports. In this paper, we (a) outline our rationale for tailoring CBT to subtypes of voice-hearing, (b) describe CBT for three putative subtypes of AVH (inner speech-based AVH, memory-based AVH, and hypervigilance AVH), and (c) discuss potential limitations and problems with such an approach. We conclude by arguing that tailoring CBT to subtypes of voice-hearing could prove to be a valuable therapeutic development, which may be especially effective when used in early intervention in psychosis services.

RESUMEN

BACKGROUND: The phenomenological heterogeneity of auditory hallucinations (AHs) means individual models struggle to account for all aspects of the experience. One alternative is that distinct subtypes of AHs exist, with each requiring their own unique explanatory model and tailored cognitive behavioural intervention strategies. AIMS: This exploratory study tested for the presence of one specific potential AH-subtype, hypervigilance hallucinations (HV-AHs). METHOD: Four specific aspects of the phenomenology of AHs (chosen on the basis of the predicted phenomenology of HV-AHs) were assessed using a semi-structured interview in 32 individual AHs taken from reports from 15 patients with psychosis. RESULTS: Cluster analysis (at the level of the individual AH-experience) offered support for the existence of a distinct HV-AH subtype, characterized by hearing threatening, externally-located voices when attention was externally-focused. Other clusters identified all shared the contrasting properties of occurring in quiet contexts when patients' attention was internally focused. CONCLUSIONS: The results offered tentative support for the existence of an HV-AH subcategorization and justifies future research in larger samples. Potential implications for models of AHs are also considered.

RESUMEN

This report from the International Consortium on Hallucinations Research considers the current status and future directions in research on psychological therapies targeting auditory hallucinations (hearing voices). Therapy approaches have evolved from behavioral and coping-focused interventions, through formulation-driven interventions using methods from cognitive therapy, to a number of contemporary developments. Recent developments include the application of acceptance- and mindfulness-based approaches, and consolidation of methods for working with connections between voices and views of self, others, relationships and personal history. In this article, we discuss the development of therapies for voices and review the empirical findings. This review shows that psychological therapies are broadly effective for people with positive symptoms, but that more research is required to understand the specific application of therapies to voices. Six key research directions are identified: (1) moving beyond the focus on overall efficacy to understand specific therapeutic processes targeting voices, (2) better targeting psychological processes associated with voices such as trauma, cognitive mechanisms, and personal recovery, (3) more focused measurement of the intended outcomes of therapy, (4) understanding individual differences among voice hearers, (5) extending beyond a focus on voices and schizophrenia into other populations and sensory modalities, and (6) shaping interventions for service implementation.

RESUMEN

The phenomenological diversity of auditory verbal hallucinations (AVH) is not currently accounted for by any model based around a single mechanism. This has led to the proposal that there may be distinct AVH subtypes, which each possess unique (as well as shared) underpinning mechanisms. This could have important implications both for research design and clinical interventions because different subtypes may be responsive to different types of treatment. This article explores how AVH subtypes may be identified at the levels of phenomenology, cognition, neurology, etiology, treatment response, diagnosis, and voice hearer's own interpretations. Five subtypes are proposed; hypervigilance, autobiographical memory (subdivided into dissociative and nondissociative), inner speech (subdivided into obsessional, own thought, and novel), epileptic and deafferentation. We suggest other facets of AVH, including negative content and form (eg, commands), may be best treated as dimensional constructs that vary across subtypes. After considering the limitations and challenges of AVH subtyping, we highlight future research directions, including the need for a subtype assessment tool.

RESUMEN

BACKGROUND AND OBJECTIVES: A recent model of a subtype of auditory verbal hallucinations (AVHs) has proposed such experiences may result from increased arousal altering auditory threat perception. METHODS: This study considered this theory using undergraduate students who undertook a new experimental paradigm, the Auditory Threat Discrimination Task (ATDT). This examined the effects of arousal on auditory threat perception (Study 1), and its relation to hallucination-proneness (Study 2). RESULTS: Study 1 (n = 66) found evidence that the high, as compared to low-arousal condition, was associated with a higher level of accurate and false threat detection (as measured by both number of hits and false-alarms). Study 2 addressed some methodological limitations of Study 1 and also found that the high as compared to low-arousal condition, was associated with a higher level of threat detection. Study 2 also found that high hallucination prone participants (n = 20) reported a higher level of perceived threat (as measured by both number of hits and false-alarms), compared to low hallucination prone participants (n = 20). LIMITATIONS: Overall limitations of the work included use of a non-clinical group. Also the increased arousal induced by the experiment was modest and may not fully represent the processes in operation in clinical participants. CONCLUSIONS: These findings provide some initial evidence that auditory threat detection increases under conditions of arousal, and are consistent with the proposal that some AVHs may result from hypervigilance to auditory threat.

RESUMEN

AIM: To investigate the effectiveness of an early intervention in psychosis (EIP) service on engagement and hospital bed usage, post-discharge. A secondary aim was to identify if there was a subgroup of patients with 'poor outcomes'. METHOD: A naturalistic study comparing engagement and hospital bed day usage of individuals who received treatment from an EIP service (n = 75) with those who presented before the service was established (n = 113). RESULTS: The EIP service demonstrated better engagement with service users in year 5 (P = 0.001). No significant differences were observed on hospital bed day usage. When 'poor outcome' cases were removed, a trend towards lower bed usage in EIP services emerged (P = 0.139). CONCLUSION: EIP services improve engagement with service users. There was not a significant reduction in hospital bed usage. However, advantages could be masked by a relatively small number of individuals with 'poor outcomes'.

RESUMEN

A number of studies have demonstrated that Early Intervention in Psychosis (EIP) services can produce improved outcomes for service users. However, the essential elements that produce these results remain elusive. This paper considers a number of hypotheses, with a particular focus on one service in the UK, which was designed according to policy guidance. It concludes that the structure of EIP services allows for the effective implementation of evidence based psychosocial interventions, which often fail to be implemented successfully within standard mental health services.
