Managing unusual sensory experiences: A feasibility trial in an At Risk Mental States for psychosis group

Personal Recovery Among People at Risk for Developing Serious Mental Health Problems: A Qualitative Systematic Review

OBJECTIVE

Personal recovery refers to a person's pursuit of a full, meaningful life despite the potentially debilitating impact of a mental illness. An evidence base describing personal recovery among people at risk for developing a mental illness is lacking, limiting the potential for mental health services to support personal recovery. To address this gap, the authors synthesized the extant research describing personal recovery among people at risk for developing a mental illness.

METHODS

A systematic search of several literature databases (MEDLINE, Embase, APA PsycInfo, Web of Science Core Collection, and Cochrane Library) was conducted to retrieve qualitative and case studies and first-person accounts. The Joanna Briggs Institute guidelines for systematic reviews were followed. Included studies reported on participants at variable risk for developing a schizophrenia spectrum, bipolar, major depressive, or borderline personality disorder. Articles were retrieved through a librarian-assisted search and through use of additional strategies (e.g., expert consultation). Abstracts were screened by the research team, and themes were developed by using thematic synthesis.

RESULTS

The 36 included articles were synthesized, and six themes were generated: difficulties and challenges; establishing an understanding of, and finding ways to cope with, one's mental health challenges; reestablishing a sense of agency and personhood; receiving support from people and services, as well as restoring relationships; reestablishing hope, meaning, and purpose; and overcoming stigma and destigmatizing mental illness in others.

CONCLUSIONS

These findings provide a conceptual foundation that can guide future research on personal recovery and clinical interventions that foster it among people at risk for mental illness.

Effects of a novel, brief psychological therapy (Managing Unusual Sensory Experiences) for hallucinations in first episode psychosis (MUSE FEP): Findings from an exploratory randomised controlled trial

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.

Understanding unusual sensory experiences: a randomised experimental study of a school-based intervention for adolescents

BACKGROUND

One in ten young people experience unusual sensory experiences (USE), such as hallucinations. From a cognitive perspective, the appraisal of USE determines the impact of these experiences. Negative appraisal, as well as other psychological processes (e.g. thinking flexibility, maladaptive schemas, anxiety/depression), is associated with more distress. Our aim was to (a) develop a universal single-session school-based intervention on USE for adolescents and (b) evaluate the effect of the intervention on appraisals of and help seeking intentions for USE.

METHODS

A randomised controlled experimental design with a one-month follow-up was used to test the effectiveness of the intervention in one school. Students (n = 223) aged 12-13 were randomised by class to a single-session intervention on USE or a control intervention (generic mental wellbeing). Participants completed measures of appraisals of and help-seeking intentions for USE at pre- and postintervention and at one-month follow-up. They also completed measures of schemas, thinking flexibility and anxiety/depression at preintervention.

RESULTS

Overall, 190 adolescents completed the main outcome measures at all three points. The intervention on USE led to a significant (p < .05) increase of positive appraisals of USE compared with the control, with effects sustained at one-month follow-up. The intervention on USE did not lead to significantly greater help-seeking intentions for USE (p = .26). Adolescents' schemas were associated with appraisals and slow thinking and anxiety/depressive symptoms with help-seeking behaviour for USE.

CONCLUSIONS

A single-session universal school-based intervention shows promise by improving appraisals of USE. Further research is required across different school populations.

What can neurodiversity tell us about inner speech, and vice versa? A theoretical perspective

Inner speech refers to the experience of talking to oneself in one's head. While notoriously challenging to investigate, it has also been central to a range of questions concerning mind, brain, and behaviour. Posited as a key component in executive function and self-regulation, inner speech has been claimed to be crucial in higher cognitive operations, self-knowledge and self-awareness. Such arguments have traditionally been supported with examples of atypical development. But variations in inner speech - and in some cases, significant diversity - in fact pose several key challenges to such claims, and raises many more questions for, language, thought and mental health more generally. In this review, we will summarise evidence on the experience and operation of inner speech in child and adult neurotypical populations, autistic people and other neurodivergent groups, and people with diverse experiences of linguistic and sensory development, including deafness. We will demonstrate that the relationship between inner speech and cognitive operations may be more complex than first assumed when explored through the lens of cognitive and neurological diversity, and the implications of that for understanding the developing brain in all populations. We discuss why and how the experience of inner speech in neurodivergent groups has often been assumed rather than investigated, making it an important opportunity for researchers to develop innovative future work that integrates participatory insights with cognitive methodology. Finally, we will outline why variations in inner speech - in neurotypical and neurodivergent populations alike - nevertheless have a range of important implications for mental health vulnerability and unmet need. In this sense, the example of inner speech offers us both a way of looking back at the logic of developmental psychology and neuropsychology, and a clue to its future in a neurodiverse world.

Prevalence of multisensory hallucinations in people at risk of transition to psychosis

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.

Managing Unusual Sensory Experiences in People with First-Episode Psychosis (MUSE FEP): a study protocol for a single-blind parallel-group randomised controlled feasibility trial

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.

The feeling, embodiment and emotion of hallucinations in first episode psychosis: A prospective phenomenological visual-ecological study using novel multimodal unusual sensory experience (MUSE) maps

BACKGROUND

Research and practice typically focus upon unimodal hallucinations, especially auditory verbal hallucinations. Contemporary research has however indicated that voice-hearing may co-occur within a broader milieu of feelings, and multimodal hallucinations may be more common than previously thought.

METHODS

An observational design asked participants to prospectively document the feeling and modality of hallucinations for one week prior to an interview. Novel visual diary methods involving drawing, writing and body-mapping generated 42 MUSE maps (multimodal unusual sensory experience), analysed with a participatory qualitative method. Twelve people took part: all experiencing hallucinations daily, accessing early intervention in psychosis services, given psychotic-spectrum diagnoses, and living in the community. The study took place during a seven-month period in 2018 at Leicestershire and Rutland's Psychosis Intervention and Early Recovery service (UK).

FINDINGS

All documented hallucinations co-occurred with bodily feelings. Feelings were localised to specific body areas, generalised across the body and extended beyond the body into peripersonal space. Co-occurring emotional feelings most commonly related to confusion, fear and frustration.

INTERPRETATION

Hallucinations were characterised by numerous feelings arising at once, often including multimodal, emotional, and embodied features. Within this study, the immediate feeling of hallucination experiences were readily communicated through prospective, visual, and ecological information gathering methods and particularly those which offer multiple modes of communication (e.g. body-map, visual, written, oral). Uptake of visual, ecological and prospective methods may enhance understandings of lived experiences of hallucinations.Funding: University of Leicester.
