A case series to test the acceptability, feasibility and preliminary efficacy of AVATAR therapy in anorexia nervosa.

BACKGROUND: Patients with anorexia nervosa tend to experience an inner "eating disorder" voice. They struggle to recognise and assert their own identity over the illness's identity and relate to it from a powerless and subordinate position. AVATAR therapy was developed to help patients with psychosis to gain greater power and control over distressing voices. The goal of this study was to test the feasibility, acceptability, safety and preliminary efficacy of an adaptation of AVATAR therapy for anorexia nervosa. METHODS: Twelve adult patients with anorexia nervosa were recruited. Ten completed an assessment session and between five to seven therapy sessions. The assessment session consisted in the creation of an avatar to represent the "eating disorder". This was accomplished by manipulating auditory and visual characteristics through a specialist computer software. During the therapy sessions, patients interacted with the avatar to assert their own desires and will. Patients completed baseline, end of intervention and follow-up (4-week) online questionnaires. A non-concurrent multiple baselines single case experimental design (SCED) was used (A1BA2). Feasibility, acceptability, safety and preliminary efficacy of the intervention were assessed. RESULTS: The therapy met pre-specified criteria relating to (1) Feasibility: sample recruited within three months; retention rate at the end of the treatment phase = 81.9%; therapy completion rate = 90.1%. (2) Safety: no serious adverse events associated with the intervention. (3) Acceptability: mean ratings = 7.5 (SD = 2.61) out of ten, on a 0-10 scale of acceptability (10 = complete satisfaction). With regards to efficacy, participants reported significantly lower levels of distress associated with the eating disorder voice and higher levels of self-compassion at the end of treatment. No other significant changes were observed in frequency of the eating disorder voice, voice's characteristics, such as omnipotence and malevolence, eating disorder symptoms and symptoms of anxiety, depression and stress. Patients' feedback indicated that the therapy had helped with their ability to stand up to the illness, make positive changes around eating, and increase their motivation to recover and self-compassion. CONCLUSION: AVATAR therapy for anorexia nervosa is feasible, acceptable and safe for patients. Larger studies are needed to test clinical efficacy. TRIAL REGISTRATION: The study was pre-registered on the clinicaltrials.gov registry (https://clinicaltrials.gov/ct2/show/NCT04778423).

People with anorexia nervosa often struggle with connecting to their identity beyond the illness. They tend to relate to the eating disorder from a powerless and submissive position. The aim of this study was to test AVATAR therapy for anorexia nervosa. The goal of the intervention was to help patients to assert themselves, their identity, will, power and desires, when confronted with the "voice" of the illness. Twelve patients with anorexia nervosa were recruited and 10 completed one assessment session and five to seven therapy sessions. During the assessment session, patients were guided by the therapist to create a representation of their illness ("the avatar") by manipulating visual and auditory characteristics through a computer software. During treatment, they were supported by the therapist to assert themselves over the illness, responding to the abusive and critical comments of the eating disorder delivered by "the avatar". Patients' qualitative feedback indicated that the therapy was meaningful to them, and that it helped to recognise their own voice as distinct from the illness. The distress perceived in relation to the eating disorder voice decreased over time, and feelings of self-compassion increased at the end of therapy. Findings point towards the acceptability and usefulness of AVATAR therapy for anorexia nervosa. Larger studies are needed expand these results.

The voice characterisation checklist: psychometric properties of a brief clinical assessment of voices as social agents.

Aim: There is growing interest in tailoring psychological interventions for distressing voices and a need for reliable tools to assess phenomenological features which might influence treatment response. This study examines the reliability and internal consistency of the Voice Characterisation Checklist (VoCC), a novel 10-item tool which assesses degree of voice characterisation, identified as relevant to a new wave of relational approaches. Methods: The sample comprised participants experiencing distressing voices, recruited at baseline on the AVATAR2 trial between January 2021 and July 2022 (n = 170). Inter-rater reliability (IRR) and internal consistency analyses (Cronbach's alpha) were conducted. Results: The majority of participants reported some degree of voice personification (94%) with high endorsement of voices as distinct auditory experiences (87%) with basic attributes of gender and age (82%). While most identified a voice intention (75%) and personality (76%), attribution of mental states (35%) to the voice ('What are they thinking?') and a known historical relationship (36%) were less common. The internal consistency of the VoCC was acceptable (10 items, α = 0.71). IRR analysis indicated acceptable to excellent reliability at the item-level for 9/10 items and moderate agreement between raters' global (binary) classification of more vs. less highly characterised voices, κ = 0.549 (95% CI, 0.240-0.859), p < 0.05. Conclusion: The VoCC is a reliable and internally consistent tool for assessing voice characterisation and will be used to test whether voice characterisation moderates treatment outcome to AVATAR therapy. There is potential wider utility within clinical trials of other relational therapies as well as routine clinical practice.

Shared Decision Making With Young People at Ultra High Risk of Psychotic Disorder.

Introduction: While the majority of young people who meet the criteria for being considered at increased risk of psychosis do not go on to develop a psychotic disorder, young people are currently being identified and treated in early intervention services. Ethical concerns have been raised concerning the decision about whether or not to provide treatment, and if so, what type of treatment. This study sought to support young people themselves to make these decisions with support from their clinician through a shared decision-making approach, facilitated by an online decision aid. Methods: This project used the International Patient Decision Aid Standards (IPDAS) to guide the development and piloting of an online decision aid across two phases: (1) qualitative, semi-structured focus groups with young people who were past clients and clinicians from an early psychosis service; and (2) pilot testing of the decision aid with clinicians and young people who were current clients to finalize the development. Results: Issues discussed by clinicians in the focus group were grouped into three main areas: (1) engagement phase; (2) assessment and priorities for treatment; and (3) initial and ongoing decision making. Clients focused on the context in which the decisions were made, including as they experienced initial feelings of resistance, and then acceptance of efforts made to describe and treat their mental health challenges. Clients highlighted the need for collaboration between themselves and their clinician, and the need to be equipped with the knowledge and tools to take care of themselves. These focus group data were used to refine the online decision aid. Pilot testing revealed that while it was overall useful and relevant, important limitations were noted by both clients and clinicians. Discussion: The use of a decision aid to facilitate shared decision making (SDM) in this area is feasible and has utility for both clients and clinicians. Use of such a tool can help to address the need to uphold the rights of young people as decision makers about their own care. Future efforts should embed decision aids within complex SDM interventions, and research to understand issues relating to implementation of these interventions.

The Experiences of Youth Mental Health Peer Workers over Time: A Qualitative Study with Longitudinal Analysis.

Peer work is a rapidly growing part of the mental health workforce, yet few studies explore the implementation of peer work in youth mental health. Qualitative focus groups were conducted with eight youth peer workers at the commencement of their employment, then at 3-months and 6-months after this time. Data were transcribed verbatim and analysed using thematic and trajectory analysis. The three main findings included: (1) there was a trajectory from fear to hope; (2) there was an improved understanding of benefits and role definition over time; and (3) there was an evolving concept of understanding shared experiences as a primary asset. Known barriers to implementing peer work are likely to occur in youth mental health settings as well. Ensuring that adequate training, change management and tailored support strategies are important to maximise the chances of successful youth peer work programs.

Open-access evidence database of controlled trials and systematic reviews in youth mental health.

AIM: To present an update to an evidence-mapping project that consolidates the evidence base of interventions in youth mental health. To promote dissemination of this resource, the evidence map has been translated into a free online database (https://orygen.org.au/Campus/Expert-Network/Evidence-Finder or https://headspace.org.au/research-database/). Included studies are extensively indexed to facilitate searching. METHODS: A systematic search for prevention and treatment studies in young people (mean age 6-25 years) is conducted annually using Embase, MEDLINE, PsycINFO and the Cochrane Library. Included studies are restricted to controlled trials and systematic reviews published since 1980. RESULTS: To date, 221 866 publications have been screened, of which 2680 have been included in the database. Updates are conducted annually. CONCLUSIONS: This shared resource can be utilized to substantially reduce the amount of time involved with conducting literature searches. It is designed to promote the uptake of evidence-based practice and facilitate research to address gaps in youth mental health.

Sulcogyral patterns and morphological abnormalities of the orbitofrontal cortex in psychosis.

Three types of OFC sulcogyral patterns have been identified in the general population. The distribution of these three types has been found altered in individuals at genetic risk of psychosis, first episode psychosis (FEP) and chronic schizophrenia. The aim of this study was to replicate and extend previous research by additionally investigating: intermediate and posterior orbital sulci, cortical thickness, and degree of gyrification/folding of the OFC, in a large sample of FEP patients and healthy controls. OFC pattern type was classified based on a method previously devised, using T1-weighted magnetic resonance images. Cortical thickness and local gyrification indices were calculated using FreeSurfer. Occurrence of Type I pattern was decreased and Type II pattern was increased in FEP patients for the right hemisphere. Interestingly, controls displayed an OFC pattern type distribution that was disparate to that previously reported. Significantly fewer intermediate orbital sulci were observed in the left hemisphere of patients. Grey matter thickness of orbitofrontal sulci was reduced bilaterally, and left hemisphere reductions were related to OFC pattern type in patients. There was no relationship between pattern type and degree of OFC gyrification. An interaction was found between the number of intermediate orbital sulci and OFC gyrification; however this group difference was specific to only the small subsample of people with three intermediate orbital sulci. Given that cortical folding is largely determined by birth, our findings suggest that Type II pattern may be a neurodevelopmental risk marker while Type I pattern may be somewhat protective. This finding, along with compromised orbitofrontal sulci thickness, may reflect early abnormalities in cortical development and point toward a possible endophenotypic risk marker of schizophrenia-spectrum disorders.
