Virtual reality in the assessment and treatment of psychosis: a systematic review of its utility, acceptability and effectiveness

Using Virtual Reality Social Environments to Promote Outcomes' Generalization of AVATAR Therapy for Distressing Voices: A Case Study

AVATAR therapy (AT) works by facilitating a 'face-to-face' dialog between the person and a digital representation (avatar) of their persecutory voice. Although there is cumulative evidence of this way of working with voices, enhancing the therapeutic focus on improved confidence and a sense of control of the voices in social situations represents a promising way to boost the generalization of therapy gains into social contexts. This paper presents a descriptive clinical case example of AVATAR_VRSocial therapy, a new augmented version of AT incorporating immersive Virtual Reality to help the person deal better with their voices in daily situations. "Laura" is a woman who was hearing a very distressing, threatening voice. She felt anxious and distressed when anticipating hearing it and would engage in safety-seeking behaviors to prevent hearing the voice. Laura was supported to stand up to her avatar and regain power over it by using assertive responses, both in active avatar dialog and when exposed to the avatar voice in VR scenarios, which turned into reduced distress when hearing the voice in her everyday life. Laura's dialog with her avatar evolved into a more explicit exploration of the meaning and the purpose of the voice in relation to previous trauma and personal relationships. The additional work in VR appeared to facilitate exposure to social situations while hearing the distressing voice, without performing seeking-safety behaviors, and to allow for practicing strategies to reduce the voice's interference, which evolved from the dialogic sessions with the personalized avatar.

Virtual reality therapy targeting ideas of reference in patients with psychosis: a single-blind parallel-group randomized controlled trial

BACKGROUND

No studies have investigated the effects of virtual reality (VR) on the persecutory idea of reference (IOR) or delusions of reference (DOR) in patients with psychosis. This study examined the efficacy and safety of VR therapy in stable outpatients with psychosis and explored relationships between primary outcomes and psychological factors using path analysis.

METHODS

Seventy-eight patients were randomly assigned to either the VR-treatment (VR-T) or VR-control (VR-C) group. The VR-T group viewed three 360° 3D videos or four animated videos; the VR-C group viewed the same seven videos with muted voices or 11 360° 3D videos of natural scenes. Pre- and post-assessments were performed using the Psychotic Symptom Rating Scale-Delusions (PSYRATS-D) and Revised Green et al. Paranoid Thought Scale (R-GPTS) as a primary outcome measure. Several self-rating scales measuring schema, depression, brooding, negative evaluation, attribution bias, and self-esteem were administered. Safety was assessed after sessions 1 and 10, and path models were constructed.

RESULTS

Between-group analysis showed a significant improvement in PSYRATS-D scores in the VR-T group compared with the VR-C group. Regarding self-rating scales, the between-group analysis revealed a significant group × time interaction only for the Social and Occupational Functioning Assessment Scale (SOFAS) score. The frequency of VR sickness was high, but its severity was mild. Fear of Negative Evaluation Scale and Beck Depression Inventory scores were found to have mediating roles.

CONCLUSIONS

VR therapy effectively reduced delusions in young, stable psychosis patients with mild and tolerable side effects. Future studies should develop diverse VR content for older populations.

AVATAR Virtual Reality Social therapy (AVATAR_VRSocial) for distressing voices and their interference in social everyday life in early psychosis: protocol of a single-blind parallel group randomised controlled feasibility study

INTRODUCTION

Around 70% of people with psychosis experience auditory verbal hallucinations (AVHs), which can cause distress and impair the social functioning of the individual. AVATAR therapy works by facilitating a 'face-to-face' dialogue between the person and a digital representation (avatar) of their persecutory voice. Although there is cumulative evidence of this way of working with voices, enhancing the therapeutic focus on improved confidence and sense of control of the voices in social situations represents a promising way to boost generalisation of therapy gains into social contexts. We aim to enhance AVATAR therapy by incorporating immersive Virtual Reality (VR) social environments aiming to help the person to deal better with their voices in daily situations.

METHODS AND ANALYSIS

A randomised controlled feasibility trial will be conducted. 40 patients aged 18 or above who are at early stages of psychosis (first episode of psychosis in the last five years) and report distressing and interfering voices will be recruited. Participants will be randomised to receive either a novel, enhanced version of AVATAR therapy (AVATAR_VRSocial) in addition to usual care or usual care alone. Assessor-blinded assessments will be conducted at baseline, 3 months (post-intervention) and 6 months (follow--up). Key therapeutic targets of AVATAR_VRSocial will be those established by the previous evidence of this approach (ie, power and control, self-esteem and future focus), while introducing exposure and management of distressing voices during social interactions. Analyses will focus on feasibility outcomes (recruitment, retention and completion rates) and preliminary estimates of intervention effects. Qualitative interviews will be carried out with participants allocated to AVATAR_VRSocial to gain a comprehensive understanding of participants' views on the acceptability of the intervention and research procedures. Thematic analysis of the qualitative interviews will assess the acceptability of the intervention, trial procedures and the new VR technology and software involved.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Ethics Commission at the Faculty of Psychology (Ruhr-Universität Bochum), and there is an independent Trial Steering Committee and Lived Experience Advisory Panel also supporting it. Findings will be disseminated through peer--reviewed publications, conference presentations and science dissemination events.

Acceptability, Usability, and Insights Into Cybersickness Levels of a Novel Virtual Reality Environment for the Evaluation of Depressive Symptoms: Exploratory Observational Study

BACKGROUND

There is a clear need for enhanced mental health assessment, depressive symptom (DS) evaluation being no exception. A promising approach to this aim is using virtual reality (VR), which entails the potential of adding a wider set of assessment domains with enhanced ecological validity. However, whilst several studies have used VR for both diagnostic and treatment purposes, its acceptance, in particular how exposure to virtual environments affects populations with psychiatric conditions remains unknown.

OBJECTIVE

This study aims to report on the acceptability, usability, and cybersickness levels of a pilot VR environment designed for the purpose of differentiating between individuals with DSs.

METHODS

The exploratory study, conducted in Italy, included 50 healthy controls and 50 young adults with mild-to-moderate DSs (without the need for a formal diagnosis). The study used an observational design with approximately 30 minutes of VR exposure followed by a self-report questionnaire battery. The battery included a questionnaire based on the Theoretical Framework of Acceptability, the System Usability Scale as well as the Simulator Sickness Questionnaire.

RESULTS

Results indicate that the majority found VR acceptable for the purposes of mental health screening and treatment. However, for diagnostics, there was a clear preference for VR to be used by mental health professionals as a supplementary tool, as opposed to a stand-alone solution. In practice, following exposure to the pilot VR environment, generally, good levels of acceptability and usability were reported, but areas in need of improvement were identified (such as self-efficacy). Self-reported cybersickness levels were comparable to literature averages but were considerably higher among those with DSs.

CONCLUSIONS

These findings raise questions about the potential interplay between underlying somatic symptoms of depression and VR-induced cybersickness and call for more attention from the scientific community both in terms of methodology as well as potential clinical and theoretical implications. Conclusively, user support indicates a potential for VR to aid mental health assessment, but further research is needed to understand how exposure to virtual environments might affect populations with varying severity and other forms of psychiatric symptoms.

Study protocol for the EYEdentify project: An examination of gaze behaviour in autistic adults using a virtual reality-based paradigm

INTRODUCTION

Autism Spectrum Condition (ASC) is characterised by difficulties in social communication and interaction, which may pose significant challenges to daily functioning throughout life. While current diagnostic methods for ASC often rely on measures based on subjective reports, there is a growing need for objective, quantifiable measures to support current clinical assessment of ASC. Eye-tracking technology records eye and gaze movements in real time and provides a direct and objective method for assessing social attention. Integrating eye-tracking within virtual reality (VR) environments presents a novel approach for capturing gaze behaviour in dynamic, ecologically valid social scenarios. This study aims to investigate whether VR-based eye information can reveal group differences in gaze behaviour between autistic adults and neurotypical controls in simulated social interactions.

METHODS

This case-control study will include 140 adults diagnosed with ASC and 50 neurotypical controls, matched by age and gender. Participants will engage in six VR-based social scenarios, which vary in social complexity and the presence of non-social distractors. Eye information will be measured using eye-tracking technology integrated into a head-mounted display. Gaze behaviour will be analysed through fixation-based metrics on parameters including number of fixations, mean fixation time, and dwell time, on predetermined Areas of Interest.

ANALYSIS

Statistical analyses will assess between-group differences in gaze behaviour as well as correlations between gaze metrics and clinical measures of social functioning, social cognition and symptom severity.

DISCUSSION

This study utilises VR-based eye-tracking to investigate novel paradigms for assessing gaze behaviour in ASC in immersive, interactive environments and aims to advance the current understanding of visual social attention in ASC. Positive outcomes from this study may support further research into VR-based eye-tracking to supplement existing clinical assessment methods.

Virtual Reality experiments in the field

Virtual Reality (VR) has paved its way into experimental psychology due to its capacity to realistically simulate real-world experiences in a controlled way. Theoretically, this technology opens the possibility to conduct experiments anywhere in the world using consumer hardware (e.g. mobile-VR). This would allow researchers to access large scale, heterogeneous samples and to conduct experiments in the field in cases where social distancing is required - e.g. during the COVID-19 pandemic. Here, we investigate the feasibility of carrying VR experiments in the field using mobile-VR through a stress inductive (public speaking task) and a relaxation (nature) task and contrast them with results in the laboratory (HTC Vive and mobile-VR). The first experiment employed a 2 (device: HTC Vive Pro (HMD) versus Wearality Sky VR smartphone adapter) x 3 (audience: 'none', 'attentive', 'inattentive') between-subjects design. Thirty-four participants took part in the experiment and completed a public speaking task. No significant difference was detected in participants' sense of presence, cybersickness, or stress levels. In the second experiment, using an inexpensive Google Cardboard smartphone adapter a 3 (between: device setting) x 2 (within: task) mixed-design was employed. Sixty participants joined the experiment, and completed a public speaking and a nature observation task. No significant difference in participants' sense of presence, cybersickness, perceived stress and relaxation were detected. Taken together, our results provide initial evidence supporting the feasibility and validity of using mobile VR in specific psychological field experiments, such as stress induction and relaxation tasks, conducted in the field. We discuss challenges and concrete recommendations for using VR in field experiments. Future research is needed to evaluate its applicability across a broader range of experimental paradigms.

Current limitations in technology-based cognitive assessment for severe mental illnesses: a focus on feasibility, reliability, and ecological validity

Cognitive impairments are frequently observed in subjects with severe mental illnesses (SMI), leading to a remarkable impact in their real-world functioning. Well-validated and gold standard instruments are available for the assessment of cognitive deficits, but different limitations should be considered, such as the need for specific training, lengthy administration times, practice effects, or reliance on subjective reports. Recent advances in digital technologies, such as ecological momentary assessments (EMA), virtual reality (VR), and passive digital phenotyping (DP), offer promising complementary approaches for capturing real-world cognitive functioning. In the current mini-review, we examine current research gaps that limit the application of these technologies, with a specific focus on feasibility, reliability and ecological validity. EMA may capture real-world functioning by increasing the number of evaluations throughout the day, but its use might be hindered by high participant burden and missing data. Furthermore, to achieve an accurate interpretation of EMA, studies should account for sampling and moment selection biases and the presence of several confounding factors. DP faces significant ethical and logistical challenges, including privacy and informed consent concerns, as well as challenges in data interpretation. VR could serve as a platform for both more ecologically valid cognitive assessments and rehabilitation interventions, but current barriers include technological and psychometric limitations, underdeveloped theoretical frameworks, and ethical considerations. Addressing these issues is crucial for ensuring that these novel technologies can effectively serve as valuable complements to traditional neuropsychological cognitive batteries.

Integrating Virtual Reality, Neurofeedback, and Cognitive Behavioral Therapy for Auditory Verbal Hallucinations (Hybrid): Protocol of a Pilot, Unblinded, Single-Arm Interventional Study

BACKGROUND

Current treatments for schizophrenia and other psychotic disorders have limited efficacy, with high rates of nonresponse to "gold standard" treatments. New approaches are therefore urgently required.

OBJECTIVE

The aims of this pilot study are to investigate the feasibility, acceptability, safety, and usability of Hybrid treatment (primary aim); and to explore Hybrid's treatment efficacy and engagement of treatment targets (secondary aim). The primary aim will be assessed via face-to-face user experience surveys on a (self-assessed) 5-point Likert scale (and qualitative open-ended questions) examining: (1) acceptability, (2) helpfulness, (3) engagement, and (4) perceived safety. We will also examine consent and completion rates, and the number of sessions attended. Our threshold for moving on to efficacy trials will be at least 70% of our participants to rate 3 and above (which corresponds to agree or strongly agree) that the intervention package was acceptable, feasible, and safe. The secondary aims will be assessed by observing whether individuals achieve self-directed modulation of high-β neurophysiological activity (neural target) and progression upwards through the VR-based exposure hierarchy (psychological target), and by assessing symptom change scores. This study developed a new treatment approach for auditory verbal hallucinations, a major symptom of psychotic disorders, that integrates advances in psychological therapy (cognitive behavioral therapy for psychosis), technology (virtual reality, VR), and neuroscience (electroencephalography-based neurofeedback).

METHODS

Hybrid takes a "symptom capture" approach using individually tailored VR-based exposure exercises. Participants (N=10) will receive the intervention package weekly over 12 face-to-face sessions. Here, participants will be progressively exposed to symptom triggers and develop methods of downregulating neural activity associated with these symptoms (neurofeedback component) while concurrently receiving clinician-delivered cognitive behavioral therapy for psychosis.

RESULTS

As of February 2025, Hybrid has commenced (unblinded) recruitment activities from Orygen clinical services in Northwestern Melbourne, Australia. A total of 75 individuals have been approached and 64 individuals have been prescreened (41 individuals were deemed eligible, 15 individuals were ineligible, and 8 individuals declined or did not respond to contact attempts) and 5 individuals have been included in the study. Of the 5 individuals who have commenced the Hybrid treatment, 4 are actively engaged in the program and 1 individual has withdrawn. We expect recruitment to conclude in July 2025 and for the results to be published in 2026.

CONCLUSIONS

The Hybrid study is piloting a novel approach that has the potential to address the shortcomings of current treatments for psychotic symptoms. If there is favorable evidence for the acceptability, feasibility, safety and usability of Hybrid, the study team will move on to efficacy trials.

Exploring the association between adolescent psychotic-like experiences and components of social performance using a multi-level virtual reality paradigm

BACKGROUND

Despite evidence linking psychotic-like experiences (PLEs) and social functioning deficits in youth at the risk of transitioning to psychosis, this association remains poorly understood. To address this, we explored the association between components of social performance and PLEs in adolescents aged 13-18 using a novel virtual reality (VR) paradigm for real-time assessment.

METHODS

Adolescents (N = 146) aged 13-18 were recruited as part of a larger cohort study conducted by the same research group (YVORI_PRO) and invited to participate via the following criteria: those reporting highly indicative positive PLEs (HIP, N = 88) and those reporting no or less indicative PLEs (no-HIP, N = 58). Self-report, behavioural and physiological components of social performance were collected using a portable VR headset and a medical wristband. Participants entered a virtual recreational area with three levels of social ambiguity and were encouraged to interact with avatars. MANOVA was performed to check for overall group differences and repeated measures ANOVAs were conducted to examine the effects of group and level of ambiguity, as well as their interaction, on daily social performance.

RESULTS

During virtual social interactions, adolescents with HIP reported higher levels of anxiety, fear of negative evaluation (FNE) and avoidance than the no-HIP group. No significant difference between groups was found for self-confidence. With increasing social ambiguity in VR, anxiety, FNE and avoidance increased in both groups, while self-confidence decreased. No significant group differences were found in behavioural or physiological components of social performance. Interpersonal distance and pulse rate increased significantly with increasing level of ambiguity, but pulse rate variability and skin conductance did not.

CONCLUSION

The results suggest that adolescents with HIP may present specific difficulties related to social performance, which may carry additional psychosis risk. The new VR social scenario appears to be an acceptable, safe and effective tool to measure social performance in adolescents experiencing PLEs.

Advances in the ecological validity of research on social cognition in schizophrenia: A systematic review of the literature

Introduction

Ecologically valid assessments need to require tasks representative of real, everyday interactions between people in a social environment (i.e., verisimilitude) and to predict aspects of real-life performance in those same interactions (i.e., veridicality). To determine how researchers interested in social cognition among people with schizophrenia currently understand and apply ecological validity in their work, we conducted a systematic review of studies that had the ecological validity of their results as an explicit objective.

Methods

We performed the described systematic review following PRISMA guidelines.

Results

Of the 18 studies reviewed, only two defined ecological validity, 15 incorporated modifications to improve their verisimilitude, eight proposed analyses to examine their veridicality, and seven aimed to achieve both objectives.

Conclusions

Our systematic review suggests that very few published studies on social cognition among people with schizophrenia have explicitly defined ecological validity, and most have focused only on the verisimilitude of the tasks required while neglecting the veridicality of the results.

Use of virtual reality to remotely train healthcare professionals in paediatric emergency tracheostomy skills: protocol for a multi-centre, non-inferiority educational interventional study with historical controls

BACKGROUND

The insertion of a tracheostomy is an established technique used to wean patients off ventilatory support, manage secretions in complex conditions, and as a potentially life-saving procedure to bypass upper airway obstruction. Life-threatening complications during aftercare are not uncommon and may be influenced by a lack of education of carers or healthcare providers of children and young people living with a tracheostomy. Education programmes designed and supported by the National Tracheostomy Safety Project are effective, but resources are not available to educate the workforce at scale. With the overarching aim of widening access to paediatric tracheostomy skills training, we present the protocol for the development and evaluation of a novel virtual reality (VR) training tool designed to simulate the emergency management of paediatric tracheostomy complications.

METHODS AND DISCUSSION

A multi-centre, non-inferiority educational interventional study with historical controls will be used to evaluate the novel VR training package. A group of 69 healthcare staff and students will have one week to use the educational intervention as often as necessary to learn paediatric emergency tracheostomy skills. The primary outcome measure is skill performance in simulation in a pre- and post-intervention structure within subjects. Participant performance will also be assessed using non-inferiority metrics against historical traditional educational control data. Secondary outcomes include knowledge gain, knowledge retention, usability, side effects, and participant satisfaction. To minimise the risk of cybersickness, teleportation was the preferred locomotion method for the user navigation within the VR environment.

TRIAL REGISTRATION

Full registration of this study was completed at ClinicalTrials.gov. The registration number is NCT06350708 and was accepted on the 4th April 2024.

Virtual reality tolerability, sense of presence and usability in Huntington disease: a pilot study

INTRODUCTION

Several studies demonstrated the utility of immersive virtual reality (VR) as a complementary approach to conventional therapy for improving motor, psychological and cognitive impairment in some pathological conditions. Our pilot study aims to evaluate for the first time: 1) sense of presence, tolerability and usability of VR immersive experience in patients with early stages of Huntington disease (eHDp) compared to healthy controls (HC); 2) correlation between the use of technology/cybersickness and the variables of presence/usability; 3) correlation between clinical characteristics (genetic, motor, functional and cognitive) and VR's variables.

METHOD

We recruited 10 eHDp and 10 age, gender and education matched HC. Participants completed questionnaires about sense of presence, usability, tolerability and technology use profile. Subjects were exposed to different VR scenarios from a first-person perspective through a standalone VR headset.

RESULTS

Our results showed no significant statistical difference between eHDp and HC for the sense of presence (p=0.910), usability (p=0.744) and tolerability (p=0.730) during the VR experience. Familiarity with the use of technology was also comparable between groups (p=0.676). Regarding correlations in eHDp group, our results showed no correlations between use of technology/tolerability and the sense of presence/usability. Moreover, clinical characteristics of eHDp (genetic, motor, functional and cognitive scores) did not influence the sense of presence, tolerability and usability.

CONCLUSION

Our research presents preliminary evidence for the applicability of VR in eHDp. These results open up the possibility to explore future applications of this methodology in rehabilitation (i.e., cognitive training, physiotherapy), diagnosis and psychological support in Huntington disease patients.

Alcohol treatment preferences and the acceptability of virtual reality therapy for treating alcohol misuse in adult drinkers

Alcohol misuse affects a large part of the population worldwide, with high relapse rates reported even post-treatment. Treatments are also not always available, for example during the COVID-19 pandemic when social distancing measures affected the availability of in-person approaches. Novel treatments like Virtual Reality Therapy (VRT), delivered via a standard VR headset or a mobile device, may offer a flexible alternative for reducing drinking and assisting relapse prevention, but little is known about their acceptability. We therefore explored the acceptability of VRT alongside the treatment preferences of adult drinkers in an online survey. Participants were asked to consider and rank order a range of treatments typically offered by healthcare services alongside standard and mobile VRT in order to determine their relative preferences. Acceptability of each treatment was also established. Additional questions addressed potential predictors of VRT's acceptability including familiarity with each treatment option presented, prior experience of VR, hazardous drinking, perceived stigma, treatment uptake attitudes, gender, ethnicity, and mental health. Of 259 participants, more than half (52.9%) were drinking at hazardous levels. The majority of respondents (86.9%) expressed a preference for in-person treatments. Cognitive Behavioral Therapy, Counseling, and 12-Step Facilitation Therapy were considered the most acceptable treatments, whereas VRT, and particularly mobile VRT, were perceived as less acceptable than traditional treatments. Treatment familiarity and preferences, prior VR experience, mental health, treatment uptake attitudes, and perceived stigma were all associated with the acceptability of VRT. Psychoeducation and familiarization processes in delivery protocols, and in-person delivery of VRT, could increase the acceptability of VRT, particularly for people who are not regular technology users, or who require concurrent mental health support.

Virtual Reality Interventions and Psychosocial Functioning in Schizophrenia Spectrum Disorders: A Systematic Review

OBJECTIVE

The objective of this study is to evaluate the effectiveness of virtual reality (VR) intervention programs that aim to improve psychosocial functioning in schizophrenia spectrum disorders and evaluate the quality assessment of these studies.

METHODS

PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline was followed to conduct this systematic review. The literature search was performed in Web of Science (WoS) and PubMed, by two independent researchers on two occasions, on 1 March 2023 and 20 August 2023. Risk of bias of the studies was evaluated by The Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies.

RESULTS

Fifteen studies met inclusion criteria, targeting social skills (n = 5), social cognitive skills (n = 7) and vocational training (n = 3). In these studies, a total of 292 participants enrolled in VR interventions and a total of 258 participants enrolled in control groups. In this systematic review, there were eight cohort studies, where seven were with a single-group pretreatment and posttreatment evaluation and one was with a control group, and one controlled trial and six randomized controlled trials were included. Several studies reported significant improvements in both psychosocial functioning and clinical symptoms, whereas others found improvements only in either psychosocial functioning or clinical symptoms, and still others found no improvements at all. The limitations of the studies include small sample sizes and standardized intervention methods. There is a very high variability in session duration, frequency and total treatment period.

CONCLUSION

Although VR intervention programs offer unique opportunities for psychosocial improvement, heterogeneity in methodologies and mixed results highlight the need for further research.

Feasibility and safety of interactive virtual reality upper limb rehabilitation in patients with prolonged critical illness

OBJECTIVES

This study investigated the feasibility and safety of interactive virtual reality rehabilitation (VRR) for patients with a critical illness and a long stay in the intensive care unit (ICU), as a motivational tool for rehabilitation.

DESIGN

Single-centre, non-randomised proof-of-concept clinical trial.

PARTICIPANTS

Adult, calm, and alert critically ill patients with a prolonged stay (≥8 days) in the ICU.

METHODS

Patients received interactive VRR therapy for upper limb rehabilitation with a VR-app designed specifically for use in bedridden patients in the supine position. Feasibility was assessed by time registrations, questionnaires for patients and physiotherapists, as well as recording of all perceived barriers. Safety was assessed by recording (changes in) vital clinical parameters, as well as minor and major adverse events.

RESULTS

Twenty patients participated in 79 VRR sessions. Median durations of different session components were 2 minutes (interquartile range [IQR] = 2min, 3min) for set-up and explanation to the patient, 10 minutes (IQR = 10min, 15min) for training time, and 2 minutes (IQR = 2min, 2min) for ending the session and cleaning. The median fun score given by the patients after each session was 9 (IQR = 8, 10) out of 10. Physiotherapists reported no barriers other than a few time-consuming technical problems. Reported problems by patients were all minor and mostly technical. No major and no minor adverse events occurred.

CONCLUSIONS

Interactive upper limb VRR is a feasible, safe, and appreciated tool to use in rehabilitation of critically ill patients during their prolonged ICU stay. Subsequent future studies should focus on the effects of VRR on neuromuscular and cognitive function and the socioeconomic impact of exergaming for rehabilitation purposes of ICU patients.

The Suite for the Assessment of Low-Level cues on Orientation (SALLO): The psychophysics of spatial orientation in virtual reality

Spatial orientation is a complex ability that emerges from the interaction of several systems in a way that is still unclear. One of the reasons limiting the research on the topic is the lack of methodologies aimed at studying multimodal psychophysics in an ecological manner and with affordable settings. Virtual reality can provide a workaround to this impasse by using virtual stimuli rather than real ones. However, the available virtual reality development platforms are not meant for psychophysical testing; therefore, using them as such can be very difficult for newcomers, especially the ones new to coding. For this reason, we developed SALLO, the Suite for the Assessment of Low-Level cues on Orientation, which is a suite of utilities that simplifies assessing the psychophysics of multimodal spatial orientation in virtual reality. The tools in it cover all the fundamental steps to design a psychophysical experiment. Plus, dedicated tracks guide the users in extending the suite components to simplify developing new experiments. An experimental use-case used SALLO and virtual reality to show that the head posture affects both the egocentric and the allocentric mental representations of spatial orientation. Such a use-case demonstrated how SALLO and virtual reality can be used to accelerate hypothesis testing concerning the psychophysics of spatial orientation and, more broadly, how the community of researchers in the field may benefit from such a tool to carry out their investigations.

Use of virtual reality in bipolar disorder: a systematic review

Virtual reality (VR) is a technology that allows to interact with recreated digital environments and situations with enhanced realism. VR has shown good acceptability and promise in different mental health conditions. No systematic review has evaluated the use of VR in Bipolar Disorder (BD). This PRISMA-compliant systematic review searched PubMed and Web of Science databases (PROSPERO: CRD42023467737) to identify studies conducted in individuals with BD in which VR was used. Results were systematically synthesized around four categories (cognitive and functional evaluation, clinical assessment, response to VR and safety/acceptability). Eleven studies were included (267 individuals, mean age = 36.6 years, 60.7% females). Six studies using VR to carry out a cognitive evaluation detected impairments in neuropsychological performance and delayed reaction times. VR was used to assess emotional regulation. No differences in well-being between VR-based and physical calm rooms were found. A VR-based stress management program reduced subjective stress, depression, and anxiety levels. VR-based cognitive remediation improved cognition, depressive symptoms, and emotional awareness. 48.7% of the individuals with BD considered VR-based cognitive remediation 'excellent', whereas 28.2% considered it 'great'. 87.2% of individuals did not report any side effects. 81.8% of studies received a global quality rating of moderate. Emerging data point towards a promising use of VR in BD as an acceptable assessment/intervention tool. However, multiple unstudied domains as comorbidity, relapse and prodromal symptoms should be investigated. Research on children and adolescents is also recommended. Further research and replication of findings are required to disentangle which VR-interventions for which populations and outcomes are effective.

Virtual reality in functional neurological disorder: a theoretical framework and research agenda for use in the real world

Functional neurological disorder (FND) is a common and disabling condition at the intersection of neurology and psychiatry. Despite remarkable progress over recent decades, the mechanisms of FND are still poorly understood and there are limited diagnostic tools and effective treatments. One potentially promising treatment modality for FND is virtual reality (VR), which has been increasingly applied to a broad range of conditions, including neuropsychiatric disorders. FND has unique features, many of which suggest the particular relevance for, and potential efficacy of, VR in both better understanding and managing the disorder. In this review, we describe how VR might be leveraged in the treatment and diagnosis of FND (with a primary focus on motor FND and persistent perceptual-postural dizziness given their prominence in the literature), as well as the elucidation of neurocognitive mechanisms and symptom phenomenology. First, we review what has been published to date on the applications of VR in FND and related neuropsychiatric disorders. We then discuss the hypothesised mechanism(s) underlying FND, focusing on the features that are most relevant to VR applications. Finally, we discuss the potential of VR in (1) advancing mechanistic understanding, focusing specifically on sense of agency, attention and suggestibility, (2) overcoming diagnostic challenges and (3) developing novel treatment modalities. This review aims to develop a theoretical foundation and research agenda for the use of VR in FND that might be applicable or adaptable to other related disorders.

Umbrella Review: Atlas of the Meta-Analytical Evidence of Early-Onset Psychosis

OBJECTIVE

Early-onset psychosis (EOP) refers to the development of psychosis before the age of 18 years. We aimed to summarize, for the first time, the meta-analytical evidence in the field of this vulnerable population and to provide evidence-based recommendations.

METHOD

We performed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant, pre-registered (PROSPERO: CRD42022350868) systematic review of several databases and registers to identify meta-analyses of studies conducted in EOP individuals to conduct an umbrella review. Literature search, screening, data extraction, and quality assessment were carried out independently. Results were narratively reported, clustered across core domains. Quality assessment was performed with the Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) tool.

RESULTS

A total of 30 meta-analyses were included (373 individual studies, 25,983 participants, mean age 15.1 years, 38.3% female). Individuals with EOP showed more cognitive impairments compared with controls and individuals with adult/late-onset psychosis. Abnormalities were observed meta-analytically in neuroimaging markers but not in oxidative stress and inflammatory response markers. In all, 60.1% of EOP individuals had a poor prognosis. Clozapine was the antipsychotic with the highest efficacy for overall, positive, and negative symptoms. Tolerance to medication varied among the evaluated antipsychotics. The risk of discontinuation of antipsychotics for any reason or side effects was low or equal compared to placebo.

CONCLUSION

EOP is associated with cognitive impairment, involuntary admissions, and poor prognosis. Antipsychotics can be efficacious in EOP, but tolerability and safety need to be taken into consideration. Clozapine should be considered in EOP individuals who are resistant to 2 non-clozapine antipsychotics. Further meta-analytical research is needed on response to psychological interventions and other prognostic factors.

PLAIN LANGUAGE SUMMARY

This umbrella review summarized the meta-analytical knowledge from 30 meta-analyses on early-onset psychosis. Early-onset psychosis refers to the development of psychosis before the age of 18 years and is associated with cognitive impairment, hospitalization, and poor prognosis. Individuals with early-onset psychosis show more cognitive impairments and abnormalities compared with controls. Clozapine was the antipsychotic with the highest efficacy for positive, negative, and overall symptoms and should be considered in individuals with early-onset psychosis.

Digitally Enhanced Psychological Assessment and Treatment of Paranoia: A Systematic Review

BACKGROUND

Paranoia is relatively common but can lead to significant distress, impairment and need for care. Digital technologies offer a valuable extension to service provision and are increasingly being integrated into healthcare. This systematic review evaluated feasibility, acceptability, and effectiveness of digitally enhanced psychological assessments and treatments for paranoia across the paranoia continuum (PROSPERO: CRD42023393257).

METHODS

Databases PsychINFO, EMBASE, MEDLINE and Web of Science were searched until 12 June 2023; the Effective Public Health Practice Project (EPHPP) quality assessment tool evaluated studies; and a narrative synthesis was conducted.

RESULTS

Twenty-seven studies met inclusion criteria (n = 3457, 23 assessment and 4 treatment, 2005-2023, most in Europe). Technologies included virtual reality (VR, n = 23), experience sampling methodology (ESM, n = 2), an app (n = 1) and a combination of VR and ESM (n = 1). Assessments involved monitoring paranoia under various virtual conditions or in everyday life. Treatments were generally integrated with Cognitive Behaviour Therapy (CBT), which involved using VR to test out threat beliefs and drop safety behaviours or using an app to support slowing down paranoid thinking. EPHPP ratings were strong (n = 8), moderate (n = 12) and weak (n = 7).

CONCLUSIONS

Digitally enhanced assessments and treatments showed promising acceptability, feasibility and treatment effectiveness. Limitations of studies include small sample sizes, lack of comparison groups and long-term data and limited randomised controlled trials. Results support the potential future integration of VR in the assessment of paranoia and show promise for treatments such as CBT, although further clinical trials are required. Investigation of other technologies is limited.

A novel psychosocial virtual reality intervention (BMT-VR) for patients undergoing hematopoietic stem cell transplantation: Pilot randomized clinical trial design and methods

BACKGROUND

Although patients undergoing hematopoietic stem cell transplantation (HSCT) must cope with psychological distress and isolation during an extended transplant hospitalization, psychosocial interventions to address these unmet needs are lacking. Virtual reality offers an innovative modality to deliver a patient-centered psychosocial intervention to address psychosocial needs of patients undergoing HSCT. However, there are currently no supportive care interventions leveraging virtual reality in patients undergoing HSCT.

OBJECTIVE

To describe the methods of a randomized clinical trial (RCT) to assess the feasibility and preliminary efficacy of a self-administered, virtual reality-delivered psychosocial intervention (BMT-VR) to improve psychological distress and quality of life (QOL) for patients hospitalized for HSCT.

METHODS

This study entails a single-center RCT of BMT-VR compared to usual transplant care in 80 patients hospitalized for HSCT. Adult patients with hematologic malignancies hospitalized for autologous or allogeneic HSCT are eligible. BMT-VR includes psychoeducation about the HSCT process, psychosocial skill building to promote effective coping and acceptance, and self-care and positive psychology skills to promote post-HSCT recovery. The primary aim is to assess the feasibility defined a priori as ≥60% of eligible patients enrolling in the study, and of those enrolled and randomized to the BMT-VR, ≥ 60% completing 4/6 BMT-VR modules. Secondary objectives include assessing the preliminary effects on psychological distress and QOL.

DISCUSSION

This is the first RCT of a virtual reality-delivered psychosocial intervention for the HSCT population. If deemed feasible, a future larger multi-site clinical trial can evaluate the efficacy of BMT-VR on outcomes for patients hospitalized for HSCT.

Using virtual reality to improve verbal episodic memory in schizophrenia: A proof-of-concept trial

Background

Schizophrenia is associated with impairments in verbal episodic memory. Strategy for Semantic Association Memory (SESAME) training represents a promising cognitive remediation program to improve verbal episodic memory. Virtual reality (VR) may be a novel tool to increase the ecological validity and transfer of learned skills of traditional cognitive remediation programs. The present proof-of-concept study aimed to assess the feasibility, acceptability, and preliminary efficacy of a VR-based cognitive remediation module inspired by SESAME principles to improve the use of verbal episodic memory strategies in schizophrenia.

Methods

Thirty individuals with schizophrenia/schizoaffective disorder completed this study. Participants were randomized to either a VR-based verbal episodic memory training condition inspired by SESAME principles (intervention group) or an active control condition (control group). In the training condition, a coach taught semantic encoding strategies (active rehearsal and semantic clustering) to help participants remember restaurant orders in VR. In the active control condition, participants completed visuospatial puzzles in VR. Attrition rate, participant experience ratings, and cybersickness questionnaires were used to assess feasibility and acceptability. Trial 1 of the Hopkins Verbal Learning Test - Revised was administered pre- and post-intervention to assess preliminary efficacy.

Results

Feasibility was demonstrated by a low attrition rate (5.88 %), and acceptability was demonstrated by limited cybersickness and high levels of enjoyment. Although the increase in the number of semantic clusters used following the module did not reach conventional levels of statistical significance in the intervention group, it demonstrated a notable trend with a medium effect size (t = 1.48, p = 0.15, d = 0.54), in contrast to the control group where it remained stable (t = 0.36, p = 0.72, d = 0.13). These findings were similar for the semantic clustering ratio in the intervention (t = 1.61, p = 0.12, d = 0.59) and control (t = 0.36, p = 0.72, d = 0.13) groups. There was no significant change in the number of recalled words in either group following VR immersion.

Discussion

This VR intervention was feasible, acceptable, and may be useful for improving the use of semantic encoding strategies. These findings support the use of more ecological approaches for the treatment of cognitive impairments in schizophrenia, such as VR-based cognitive remediation.

Effectiveness of applied and casual games for young people's mental health: A systematic review of randomised controlled studies

Many youth experience mental health problems and digital games hold potential as mental health interventions. This systematic review provides an overview of randomised controlled studies assessing the effectiveness of digital applied and casual games for improving mental health in youth aged 6-24 years. A systematic search of PsycINFO, Web of Science and Pubmed yielded 145 eligible studies. Studies on (sub)clinical participant samples (n = 75) most often focused on attention-deficit/hyperactivity disorder (ADHD), autism and anxiety. Applied games were found most effective for improving social skills, verbal memory and anxiety, whereas casual games were found most effective for improving depression, anxiety and ADHD. Studies involving healthy youth (n = 70) were grouped into papers examining anxiety in medical settings, momentary effects on positive and negative affect, and papers employing a longitudinal design measuring mental health trait outcomes. Promising results were found for the use of games as distraction tools in medical settings, and for applied and casual games for improving momentary affect. Overall, our findings demonstrate the potential of digital games for improving mental health. Implications and recommendations for future research are discussed, such as developing evaluation guidelines, clearly defining applied games, harmonising outcome measures, including positive outcomes, and examining nonspecific factors that may influence symptom improvement as well.

Effectiveness and User Experience of Virtual Reality for Social Anxiety Disorder: Systematic Review

BACKGROUND

Social anxiety disorder (SAD) is a debilitating psychiatric disorder that affects occupational and social functioning. Virtual reality (VR) therapies can provide effective treatment for people with SAD. However, with rapid innovations in immersive VR technology, more contemporary research is required to examine the effectiveness and concomitant user experience outcomes (ie, safety, usability, acceptability, and attrition) of emerging VR interventions for SAD.

OBJECTIVE

The aim of this systematic review was to examine the effectiveness and user experience of contemporary VR interventions among people with SAD.

METHODS

The Cochrane Library, Emcare, PsycINFO, PubMed, ScienceDirect, Scopus, and Web of Science databases were searched between January 1, 2012, and April 26, 2022. Deduplicated search results were screened based on title and abstract information. Full-text examination was conducted on 71 articles. Studies of all designs and comparator groups were included if they appraised the effectiveness and user experience outcomes of any immersive VR intervention among people with SAD. A standardized coding sheet was used to extract data on key participant, intervention, comparator, outcome, and study design items.

RESULTS

The findings were tabulated and discussed using a narrative synthesis. A total of 18 studies met the inclusion criteria.

CONCLUSIONS

The findings showed that VR exposure therapy-based interventions can generally provide effective, safe, usable, and acceptable treatments for adults with SAD. The average attrition rate from VR treatment was low (11.36%) despite some reported user experience difficulties, including potential simulator sickness, exposure-based emotional distress, and problems with managing treatment delivered in a synchronous group setting. This review also revealed several research gaps, including a lack of VR treatment studies on children and adolescents with SAD as well as a paucity of standardized assessments of VR user experience interactions. More studies are required to address these issues.

Gambling and virtual reality: unraveling the illusion of near-misses effect

Introduction

Studying gambling behavior is a crucial element in reducing the impact of problem gambling. Nevertheless, most current research is carried out in controlled laboratory settings rather than real-life situations, which raises concerns about how applicable the findings are in the broader context. Virtual reality (VR) has proven to be a valuable tool and has been utilized in various experimental scenarios. A limited number of studies have employed VR to investigate gambling behaviors, and few have explored them in an older adolescent context.

Methods

This study examined the behavioral and physiological effects of gambling behavior, including problem gambling, gaming addiction, and risk-taking decision-making in a sample of 36 high-school students aged between 18 to 20 years using an ad-hoc constructed VR scenario designed to simulate a slot-machine platform.

Results

The behavioral results highlighted that participants reporting more problem gambling were sensitive to near-misses: i.e., they bet more after near-misses than after losses. This result may reflect the false belief that gamblers, after near-misses, are closer to winning. Physiological data showed that participants exhibited heart rate deceleration during the anticipation of the outcome, which has been suggested to represent a marker of feedback anticipation processing and hyposensitivity to losses.

Discussion

Overall, this study provides evidence for a new VR tool to assess gambling behaviors and new insights into gambling-related behavioral and physiological factors. Implications for the treatment of problem gambling are discussed.

Advanced Visualization Engineering for Vision Disorders: A Clinically Focused Guide to Current Technology and Future Applications

Head-mounted visualization technology, often in the form of virtual, augmented, and mixed reality (VAMR), has revolutionized how visual disorders may be approached clinically. In this manuscript, we review the available literature on VAMR for visual disorders and provide a clinically oriented guide to how VAMR technology has been deployed for visual impairments. The chief areas of clinical investigation with VAMR are divided include (1) vision assessment, (2) vision simulation, and (3) vision rehabilitation. We discuss in-depth the current literature of these areas in VAMR and upcoming/future applications to combat the detrimental impact of visual impairment worldwide.

How institutional logics shape the adoption of virtual reality in mental health care: A qualitative study

Objective

To analyse institutional logics' role in adopting virtual reality in mental health care.

Methods

Data were collected via qualitative, semi-structured interviews with four frontline staff and seven administrative and service staff, two focus group interviews with three frontline staff and four administrative and service staff, and via participant observation in meetings between stakeholders working on virtual reality. Data were collected from May 2021 to February 2022, analysed using thematic analysis, and theoretically driven by the framework of Institutional logics.

Results

We identified two different forms of institutional logics being drawn upon by frontline staff and administrative and service staff, respectively, when working with the adoption of virtual reality in mental health care. Frontline staff drew mainly on a Professional logic; administrative and service staff drew on a Diffusion logic. Each logic defined a unique focal point, causal pathway, and perceptions of a meaningful adoption process for virtual reality.

Conclusions

By taking institutional logics as our theoretical and analytical point of departure, this study demonstrates how the meaning of virtual reality and its adoption in mental health care is grounded in multiple and sometimes conflicting institutional logics. Acknowledging the existence and influence of often multiple institutional logics in the adoption process is crucial to guide the future adoption of virtual reality in mental health care. Organising collaborative venues for stakeholders where their multiple institutional logics are made the subject of joint reflection is essential to counter frictions.

Virtual reality-assisted assessment of paranoid ideation in forensic psychiatric inpatients: A mixed-methods pilot study

Background

Reliable and valid assessment of paranoia is important in forensic psychiatry for providing adequate care. VR technology may add to current assessment procedures, as it enables observation within realistic (social) situations resembling the complexity of everyday life. VR constitutes a promising tool within forensics, due to the restricted nature of forensic psychiatric hospitals and ethical challenges arising from observing potentially dangerous behaviors in real life.

Objective

To investigate the feasibility of VR assessment for paranoid ideation in forensic psychiatric inpatients qualitatively by assessing the experiences of patients and a clinician, and to explore how the VR measures relate to established clinical measures.

Methods

One clinician (experienced psychiatrist) and 10 forensic psychiatric inpatients with a history or suspicion of paranoid ideation were included. Patients participated in two immersive VR scenarios (bus and supermarket) during which paranoia was assessed by the clinician. Qualitative interviews were performed with patients and the clinician performing the assessment to investigate experiences and feasibility. Further, measures of paranoia, social anxiety, and positive symptoms were obtained.

Results

Nine out of 10 participants with varying levels of paranoid ideation completed the assessment. Manifest inductive content analyses of the interviews revealed general experiences, advantages such as enabling observing participants from a different perspective, and challenges of the VR assessment, such as a lack of objectivity and the laboriousness of the assessment for the clinician. Although more paranoia was experienced during the supermarket scenario, correlates with classical measures were only significant for the bus scenario.

Discussion

The VR assessment was appreciated by most patients and the clinician. Based on our results short, standardized VR assessment scenarios are feasible, however, they do not appear reliable or objective for assessing paranoia. The clinical usefulness is most likely as a collaborative tool and add-on measure to existing methods.

Integrating a virtual reality relaxation clinic within acute psychiatric services: A pilot study

People with acute psychiatric conditions experience heightened stress, which is associated with worsened symptoms and increased violence on psychiatric wards. Traditional stress management techniques can be challenging for patients. Virtual reality (VR) relaxation appears promising to reduce stress; however, research on VR for psychiatric wards is limited. This mixed-methods study investigated feasibility and acceptability of integrating a VR relaxation clinic within acute psychiatric services. The study evaluated a VR relaxation session for inpatients and outpatients with acute psychiatric conditions (N = 42) and therapists' (N = 6) experience facilitating VR sessions for patients. Self-report assessments of psychological wellbeing were completed by patients pre- and post-VR. Patients and therapists provided qualitative feedback. The number of violent incidents and restrictive practices on the wards in the 12 weeks before VR implementation was compared to the first 12 weeks of VR. Post-VR, there were statistically significant increases in patients' relaxation, happiness, and connectedness to nature, and decreases in stress, anxiety, and sadness. Qualitative findings indicate patients found sessions enjoyable, relaxing, and helpful. Therapists provided positive feedback but highlighted practical challenges. Violent incidents and restrictive practices halved during VR implementation. VR relaxation appears feasible and acceptable in acute services. Larger studies should evaluate potential impact on psychiatric wards.

Beyond the Asylum Walls: Tracing the Tapestry of Mental Health Interventions Across Eras and Cultures

This article offers an extensive review of the changing field of mental health therapies, charting a transformational path from traditional methods to modern breakthroughs and speculating on potential future developments. The story develops by investigating historical viewpoints while reflecting on the present and highlighting the lessons learned and their impact on contemporary practices. We have advanced from the stigmatized constraints of asylums to a paradigm that puts human rights, dignity, and individualized, culturally sensitive treatment first. Modern methods are much more varied and evidence-based, from cutting-edge technical advancements to evidence-based psychotherapies. The ethical considerations arising from the delicate balance of pharmacological therapies underline the responsibility of administering drugs that significantly affect mental health. Cultural factors become a pillar, highlighting how crucial cultural sensitivity is to promoting tolerance. By acknowledging how many facets of the human experience are interrelated, holistic methods help close the gap between the mind and body. Integrative medicine and alternative therapies represent a shift away from reductionist approaches and toward a holistic viewpoint. The delivery of mental health treatment is being reimagined by technological advancements, with virtual and digital environments opening up new access and support channels. These developments cut beyond regional boundaries, reinventing conventional therapy dynamics and paving the way for individualized therapies. Cultural concerns highlight the significance of cultural competency in navigating the complex mental health treatment system and adapting interventions to fit the particular requirements of various cultural contexts. With telepsychiatry, virtual reality, and artificial intelligence among the new technologies that promise to further revolutionize mental health therapies, the essay looks to the future. This review concludes by imagining a day when mental health is prioritized, therapies are available, and the diversity of human experience is valued. The path to a society that values, nurtures, and celebrates mental health continues.

Study protocol for virtual leisure investigating the effect of virtual reality-delivered stress reduction, entertainment and distraction on the use of coercion and need-based medication and patient satisfaction at a closed psychiatric intensive care unit - a mixed-methods pilot clinical trial

INTRODUCTION

The environment at a psychiatric inpatient ward can lead to emotional distress and behavioural deviations in vulnerable individuals potentially resulting in conflicts, increased use of need-based medication and coercive actions, along with low satisfaction with treatment. To accommodate these challenges, recreational and entertaining interventions are recommended. The tested interventions have, however, shown varying effects and demand a high degree of planning and staff involvement while being difficult to adapt to individual needs. Virtual reality (VR) may help overcome these challenges.

METHODS AND ANALYSIS

The study is a mixed-methods clinical trial with a target sample of 124 patients hospitalised at a closed psychiatric ward in the capital region of Denmark. Outcomes (eg, coercion, need-based medication and perceived stress) for a 12-month period where all patients are offered VR-based recreational experiences during their hospitalisation will be compared with outcomes for a 12-month period where VR is not offered. Feasibility and acceptability will be explored with qualitative interviews supplemented with non-participant observations and focus groups. The study began on 1 January 2023, and we expect to complete data collection by 31 December 2024.

ETHICS AND DISSEMINATION

The study is registered at Danish Data Protection Agency (j.no P-2022-466) and is approved by the Committee on Health Research Ethics of the capital region of Denmark (j.no 22013313). All patients will be required to provide informed consent. Results from this study will be disseminated via peer-reviewed journals and congress/consortium presentations.

TRIAL REGISTRATION NUMBER

NCT05654740.

Examination of gaze behaviour in social anxiety disorder using a virtual reality eye-tracking paradigm: protocol for a casecontrol study

INTRODUCTION

Social anxiety disorder (SAD) has an early onset, a high lifetime prevalence, and may be a risk factor for developing other mental disorders. Gaze behaviour is considered an aberrant feature of SAD. Eye-tracking, a novel technology device, enables recording eye movements in real time, making it a direct and objective measure of gaze behaviour. Virtual reality (VR) is a promising tool for assessment and diagnostic purposes. Developing an objective screening tool based on examination of gaze behaviour in SAD may potentially aid early detection. The objective of this current study is, therefore to examine gaze behaviour in SAD utilising VR.

METHODS AND ANALYSIS

A case-control study design is employed in which a clinical sample of 29 individuals with SAD will be compared with a matched healthy control group of 29 individuals. In the VR-based eye-tracking paradigm, participants will be presented to stimuli consisting of high-res 360° 3D stereoscopic videos of three social-evaluative tasks designed to elicit social anxiety. The study will investigate between-group gaze behaviour differences during stimuli presentation.

ETHICS AND DISSEMINATION

The study has been approved by the National Committee on Health Research Ethics for the Capital Region of Denmark (H-22041443). The study has been preregistered on OSF registries: https://doi.org/10.17605/OSF.IO/XCTAKAll participants will be provided with written and oral information. Informed consent is required for all the participants. Participation is voluntarily, and the participants can at any time terminate their participation without any consequences. Study results; positive, negative or inconclusive will be published in relevant scientific journals.

Using virtual reality to assess gesture performance deficits in schizophrenia patients

Introduction

Gesture performance deficits are prevalent in schizophrenia patients and are strongly associated with poor social communication skills and community functioning, affecting their overall quality of life. Currently, video-recording technology is widely used in clinical settings to assess gesture production deficits in schizophrenia patients. Nevertheless, the subjective evaluation of video-recordings can encumber task assessment. The present study will aim to use virtual reality to examine its potential use as an alternative tool to objectively measure gesture performance accuracy in schizophrenia patients and healthy controls.

Methods

Gesture performance in the virtual reality setting will be based on the well-established Test of Upper Limb Apraxia. Participants will be immersed in a virtual environment where they will experience themselves being embodied in a collocated virtual body seen from a first-person perspective. Motion trackers will be placed on participants' hands and elbows to track upper body movements in real-time, and to record gesture movement for later analysis. Participants will see a virtual agent sitting across from them, with a virtual table in between. The agent will perform various types of gestures and the participants' task will be to imitate those gestures as accurately as possible. Measurements from the tracking devices will be stored and analyzed to address gesture performance accuracy across groups.

Discussion

This study aims to provide objective measurements of gesture performance accuracy in schizophrenia patients. If successful, the results will provide new knowledge to the gesture literature and offer the potential for novel therapeutic interventions using virtual reality technologies. Such interventions can improve gesturing and thus advance social communication skills in schizophrenia patients.

Factors associated with the outcomes of a novel virtual reality therapy for military veterans with PTSD: Theory development using a mixed methods analysis

BACKGROUND

Multi-modular motion-assisted memory desensitization and reconsolidation therapy (3MDR) is a new psychological intervention for people with post-traumatic stress disorder (PTSD). 3MDR is immersive, delivered in a virtual reality environment, and emphasises engagement, recollection and reprocessing.

OBJECTIVE

Through a theory-driven examination of data relating to 10 out of 42 UK military veterans taking part in a trial of 3MDR, the principal objective was to explore the complex interrelationships between people, interventions and context and to investigate how factors within these domains interacted in specific outcome typologies.

METHOD

Quantitative and qualitative data relating to 10 trial participants were derived from: researcher-assessed and self-report clinical measures; interviews; physiological recordings; words describing thoughts and feelings during therapy; and subjective unit of distress scores. Using a convergent mixed methods approach, data were tabulated using a person, intervention and context model. Participant summaries were grouped into outcome typologies, followed by an analysis of data convergence and divergence within each and an interpretation of identified patterns.

RESULTS

Three outcome response typologies were identified: dramatic improvement, moderate improvement and minimal improvement. Within the person domain, factors associated with outcomes included walking capacity, commitment and ability to complete therapy, and levels of subjective distress. Within the intervention domain, factors associated with outcomes related to image selection and use, therapeutic alliance and orientations towards the tailoring of sessions. Within the context domain, factors associated with outcomes included reactions to the therapy environment. The patterning of secondary outcomes broadly corresponded with primary outcomes within each typology. Alongside patterned data differentiating aspects of the person, intervention and context domains, within the three response typologies data also existed where no obvious patterning was detected.

CONCLUSIONS

The model developed here may have novel value in evaluating a range of personalised interventions, but further work is needed before confident assertions can be made of who is likely to benefit from 3MDR specifically.

Integrating digital interventions with clinical practice in youth mental health services

OBJECTIVE

Integrating digital technologies with clinical practice promises to improve access and enhance care in the context of high service demand and constrained capacity.

METHOD

We outline the emerging research in the integration of digital tools in clinical care, known as blended care, and provide case examples of mental health technology platforms currently in use, summarise findings regarding novel technologies such as virtual reality, and outline real-world implementation challenges and potential solutions.

RESULTS

Recent evidence shows that blended care approaches are clinically effective and improve service efficiency. Youth-specific technologies such as moderated online social therapy (MOST) are achieving a range of positive clinical and functional outcomes, while emerging technologies like virtual reality have strong evidence in anxiety disorder, and accumulating evidence in psychotic conditions. Implementation science frameworks show promise in helping overcome the common challenges faced in real-world adoption and ongoing use.

CONCLUSION

The integrated, blended use of digital mental health technologies with face-to-face clinical care has the potential to improve care quality for young people while helping overcome the growing challenges faced by youth mental health service providers.

VR-SOAP, a modular virtual reality treatment for improving social activities and participation of young people with psychosis: a study protocol for a single-blind multi-centre randomized controlled trial

BACKGROUND

Young people with a psychotic disorder have the same social goals as their healthy peers, but their social networks are smaller, they participate less often in leisure activities and are less successful in work and education. Causes of these problems are multifaceted, but culminate in difficulties with interacting in daily life social situations. Current treatments have only moderate effects on social functioning and often target one specific domain. Virtual reality (VR) has the potential to improve the treatment of social interaction difficulties. We developed a modular VR treatment for social functioning and participation (VR-SOAP). In this study, the effect of this intervention will be investigated in a randomized controlled trial (RCT).

METHODS

A total of 116 participants (age 18-40) with a DSM-5 diagnosis of schizophrenia spectrum or other psychotic disorder and problems with social functioning will be recruited from mental healthcare institutes in the Netherlands. Participants will be randomized to the experimental condition (VR-SOAP) or active VR control condition (VRelax). VR-SOAP consists of 14 sessions and 5 modules addressing causes of impaired social functioning: four optional modules (1-4) and one fixed module (5). Vrelax consists of 14 sessions that entail psychoeducation, stress management, relaxation techniques, and the exploration of relaxing environments in VR. Primary outcomes are quantity and quality of social contacts, leisure activities and social participation, measured with the experience sampling method (ESM). Secondary outcomes are psychiatric symptoms, social behaviour, social cognition, self-esteem, self-stigma and paranoid thoughts. Treatment effects will be compared at pre-treatment (baseline), post-treatment and at 6-month follow-up.

DISCUSSION

If VR-SOAP proves to be effective, it provides therapists with a much-needed tool to improve social functioning of young adults with a psychotic disorder. Additionally, since the treatment consists of multiple modules targeting different transdiagnostic factors, this trial might provide input for new treatments to improve social functioning in a range of symptoms and disorders, e.g. mood, autism spectrum and anxiety disorders.

TRIAL REGISTRATION

On the 10th of November 2021, this trial was registered prospectively in the Dutch Trial Register as NL9784 .

Co-design of a Virtual Reality Cognitive Remediation Program for Depression (bWell-D) With Patient End Users and Clinicians: Qualitative Interview Study Among Patients and Clinicians

BACKGROUND

Major depressive disorder (MDD) is the leading cause of global disability; however, the existing treatments do not always address cognitive dysfunction-a core feature of MDD. Immersive virtual reality (VR) has emerged as a promising modality to enhance the real-world effectiveness of cognitive remediation.

OBJECTIVE

This study aimed to develop the first prototype VR cognitive remediation program for MDD ("bWell-D"). This study gathered qualitative data from end users early in the design process to enhance its efficacy and feasibility in clinical settings.

METHODS

Semistructured end-user interviews were conducted remotely (n=15 patients and n=12 clinicians), assessing the participants' perceptions and goals for a VR cognitive remediation program. Video samples of bWell-D were also shared to obtain feedback regarding the program. The interviews were transcribed, coded, and analyzed via thematic analysis.

RESULTS

End users showed an optimistic outlook toward VR as a treatment modality, and perceived it as a novel approach with the potential of having multiple applications. The participants expressed a need for an engaging VR treatment that included realistic and multisensorial settings and activities, as well as customizable features. Some skepticism regarding its effectiveness was also reported, especially when the real-world applications of the practiced skills were not made explicit, as well as some concerns regarding equipment accessibility. A home-based or hybrid (ie, home and clinic) treatment modality was preferred.

CONCLUSIONS

Patients and clinicians considered bWell-D interesting, acceptable, and potentially feasible, and provided suggestions to enhance its real-world applicability. The inclusion of end-user feedback is encouraged when developing future VR programs for clinical purposes.

Application of Immersive Virtual Reality for Assessment and Intervention in Psychosis: A Systematic Review

Virtual reality (VR) has emerged as a safe and non-invasive technology for the assessment of psychotic symptoms, social and cognitive impairments, and psychosocial intervention in improving outcomes in psychosis. This study systematically reviewed the current state of evidence in applying semi- and fully immersive VR for assessing and treating patients with psychosis. A systematic review was conducted adhering to the PRISMA statement and was conducted in Embase, PsycINFO, and PubMed databases for articles published between January 2013 and April 2022, which identified 28 eligible studies, including 12 for assessment and 16 for intervention. In the assessment studies, not all VR tasks could distinguish the differences between patients and healthy controls regarding their physiological responses, paranoid ideation, and certain aspects of cognitive functioning such as memory bias on the object tasks. Comparatively, VR-based interventions are more promising, especially for improving cognitive impairments, social skills, agoraphobic avoidance, negative and positive affective states, auditory verbal hallucination, paranoid ideation and persecutory delusions, and other psychiatric symptoms in patients. We conclude that more rigorous studies are needed to confirm treatment effectiveness and to understand the underlying mechanism of VR-based intervention for psychotic disorders. Future studies should also improve the reliability and validity of VR-based assessments for psychotic disorders.

Using 360-degree immersive videos to assess multiple transdiagnostic symptoms: A study focusing on fear of negative evaluation, paranoid thoughts, negative automatic thoughts, and craving

Over the last 20 years, virtual reality (VR) has gained a great interest for both assessment and treatment of various psychopathologies. However, due to high costs and material specificity, VR remains disadvantageous for clinicians. Adopting a multiple transdiagnostic approach, this study aims at testing the validity of a 360-degree immersive video (360IV) for the assessment of five common psychological symptoms (fear of negative evaluation, paranoid thoughts, negative automatic thoughts, craving for alcohol and for nicotine). A 360IV was constructed in the Darius Café and included actors behaving naturally. One hundred and fifty-eight adults from the general population were assessed in terms of their proneness towards the five symptoms, were then exposed to the 360IV and completed measures for the five state symptoms, four dimensions of presence (place, plausibility, copresence and social presence illusions) and cybersickness. Results revealed that the five symptoms occurred during the immersion and were predicted by the participants' proneness towards these symptoms. The 360IV was also able to elicit various levels of the four dimensions of presence while producing few cybersickness. The present study provides evidence supporting the use of the 360IV as a new accessible, ecological, and standardized tool to assess multiple transdiagnostic symptoms.

Using the Theoretical Domains Framework to Inform the Implementation of Therapeutic Virtual Reality into Mental Healthcare

Evidence supporting the efficacy of therapeutic virtual reality (VR) for mental health conditions is rapidly growing. However, little is known about how best to implement VR, or the challenges perceived by treatment providers. This study aimed to (1) synthesis perspectives of staff working in private mental healthcare and (2) use the Theoretical Domains Framework (TDF) and Behaviour Change Wheel (BCW) to identify mechanisms of change targets and intervention functions to facilitate its clinical implementation. Semi-structured interviews were conducted with clinicians (n = 14) and service managers (n = 5) working in a major private mental health hospital in Victoria, Australia. Transcripts were coded using framework analysis to identify relevant TDF domains. Specific belief statements were generated and coded as a barrier and/or facilitator and thematically organised within domains. Domains were ranked for importance based on frequency, elaboration, and evidence of conflicting beliefs. Using the BCW, domains were mapped to their respective COM-B components and indicated intervention functions. A total of 11 TDF domains were identified as relevant to early-stage implementation of therapeutic VR. Three domains were judged as highly important (beliefs about consequences; environmental context and resources; knowledge), while seven domains were judged as moderately important (social/professional role and identity; emotions; skills; memory, attention, and decision processes; intentions; beliefs about capabilities; social influences). Based on current data, we propose a theory-informed roadmap to promote VR uptake in mental healthcare services. A priority for intervention development should be addressing knowledge gaps and attitudinal barriers (e.g., safety concerns) with education and training.

Technology in psychology: a bibliometric analysis of technology-based interventions in clinical and health psychology

This study aimed to identify, synthesize, and evaluate the current state of research on the use of technology-based interventions in clinical psychology through 2017 as a recent innovative area of study. It was intended to provide a critical overview of trends in different tools and populations and identify future areas of interest. This paper focuses on studies published in psychological interventions in childhood, adolescents, adults, and geriatric populations using new technologies, including web-based intervention, virtual reality, augmented reality, mobile applications, and robotics, with particular attention to methodology. To achieve this aim, a systematic search was made in the ISI Web of Science for intervention, psychology, and the technological tools previously mentioned. The results of the study show that the use of information and communication technologies in psychology has been an innovative and growing field of study for the last 10 years. In total, 743 were included in this study. A growing trend has been observed in publications related to psychology and the use of technologies since 2007. Resea0rch topics were focused mainly on interventions on specific problems or disorders such as depression. The largest number of publications were found for the web-based intervention, in randomized clinical trials and applied to adults.

A dual-task-embedded virtual reality system for intelligent quantitative assessment of cognitive processing speed

Introduction

Processing speed is defined as the ability to quickly process information, which is generally considered as one of the affected cognitive functions of multiple sclerosis and schizophrenia. Paper-pencil type tests are traditionally used in the assessment of processing speed. However, these tests generally need to be conducted under the guidance of clinicians in a specific environment, which limits their application in cognitive assessment or training in daily life. Therefore, this paper proposed an intelligent evaluation method of processing speed to assist clinicians in diagnosis.

Methods

We created an immersive virtual street embedded with Stroop task (VR-Street). The behavior and performance information was obtained by performing the dual-task of street-crossing and Stroop, and a 50-participant dataset was established with the label of standard scale. Utilizing Pearson correlation coefficient to find the relationship between the dual-task features and the cognitive test results, and an intelligent evaluation model was developed using machine learning.

Results

Statistical analysis showed that all Stroop task features were correlated with cognitive test results, and some behavior features also showed correlation. The estimated results showed that the proposed method can estimate the processing speed score with an adequate accuracy (mean absolute error of 0.800, relative accuracy of 0.916 and correlation coefficient of 0.804). The combination of Stroop features and behavior features showed better performance than single task features.

Discussion

The results of this work indicates that the dual-task design in this study better mobilizes participants' attention and cognitive resources, and more fully reflects participants' cognitive processing speed. The proposed method provides a new opportunity for accurate quantitative evaluation of cognitive function through virtual reality.

The use of virtual reality and augmented reality in psychosocial rehabilitation for adults with neurodevelopmental disorders: A systematic review

Objectives

Virtual reality and augmented reality have been used in psychosocial rehabilitation for adults with neurodevelopmental disorders in recent years, to provide functional training in a scaffolded and appealing manner. This systematic review attempted to evaluate (1) how virtual reality or augmented reality technology was deployed, when used as an intervention for adults with neurodevelopmental disorders; and (2) how virtual or augmented reality-assisted psychosocial rehabilitation programs impacted on the functional domains of community living, employment and social participation.

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was adopted and a search of publications between June 2012 and June 2022 was carried out. The target groups were adults with schizophrenia/schizoaffective disorders, autism spectrum disorder, intellectual disabilities and attention deficit hyperactivity disorder. Interventions that targeted at least one functional domain were included.

Results

The database search generated 1,267 records and 38 studies met the inclusion criteria. Three studies utilized augmented reality while the rest utilized virtual reality. The virtual scenarios were displayed in various ways, such as head-mounted displays, computer screens, mobile devices and cave rooms. A few studies also used features such as speech recognition, eye tracking and motion-capture device to provide real-time feedback to participants during rehabilitation. Eleven studies reported interventions that addressed community living, 15 studies addressed vocational skills and nine studies trained participants in social skills or social cognition. Three studies sought to improve quality of life using virtual scenarios to expose participants to various situations. Majority of these studies reported preliminary promising results, with improvement in the functional domains addressed. However, several studies had small sample sizes and many single-arm pretest-posttest studies were assessed to be of serious or critical risk of bias.

Conclusion

Virtual reality and augmented reality are deployed in various ways to augment psychosocial rehabilitation for adults with neurodevelopmental disorders. Most interventions target skills training or strategy learning in the areas of community living, work and social participation. Preliminary positive findings of their effects on functional performance were reported. Larger and robust studies using ecologically valid outcome measures will be needed to establish their effects on real-world functional outcomes.

Virtual reality in the diagnostic and therapy for mental disorders: A systematic review

BACKGROUND

Virtual reality (VR) technologies are playing an increasingly important role in the diagnostics and treatment of mental disorders.

OBJECTIVE

To systematically review the current evidence regarding the use of VR in the diagnostics and treatment of mental disorders.

DATA SOURCE

Systematic literature searches via PubMed (last literature update: 9^th of May 2022) were conducted for the following areas of psychopathology: Specific phobias, panic disorder and agoraphobia, social anxiety disorder, generalized anxiety disorder, posttraumatic stress disorder (PTSD), obsessive-compulsive disorder, eating disorders, dementia disorders, attention-deficit/hyperactivity disorder, depression, autism spectrum disorder, schizophrenia spectrum disorders, and addiction disorders.

ELIGIBILITY CRITERIA

To be eligible, studies had to be published in English, to be peer-reviewed, to report original research data, to be VR-related, and to deal with one of the above-mentioned areas of psychopathology.

STUDY EVALUATION

For each study included, various study characteristics (including interventions and conditions, comparators, major outcomes and study designs) were retrieved and a risk of bias score was calculated based on predefined study quality criteria.

RESULTS

Across all areas of psychopathology, k = 9315 studies were inspected, of which k = 721 studies met the eligibility criteria. From these studies, 43.97% were considered assessment-related, 55.48% therapy-related, and 0.55% were mixed. The highest research activity was found for VR exposure therapy in anxiety disorders, PTSD and addiction disorders, where the most convincing evidence was found, as well as for cognitive trainings in dementia and social skill trainings in autism spectrum disorder.

CONCLUSION

While VR exposure therapy will likely find its way successively into regular patient care, there are also many other promising approaches, but most are not yet mature enough for clinical application.

Effects of virtual reality working memory training on event-based prospective memory in patients with major depressive disorder

BACKGROUND

Event-based prospective memory (EBPM) refers to remembering to perform delayed intention when specific events occur. EBPM deficit is present in patients with major depressive disorder (MDD) and hinders recovery from the illness. Working memory training (WMT) has been reported to enhance EBPM but its effect on EBPM in MDD remains unclear. We investigated whether virtual reality (VR)-based WMT can improve EBPM in MDD patients.

METHODS

Forty-six MDD patients and 41 healthy controls (HC) were recruited. Among the former ones, the first 23 consecutive patients were allocated to the experimental group (MDD-VR) and the next 23 consecutive patients to the waitlist control group (MDD-W). EBPM accuracy was used to assess EBPM performance. Hamilton Depression Rating Scale (HDRS) and Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ) were employed to assess the cognitive functions and the depressive symptoms.

RESULTS

At baseline, EBPM accuracy did not significantly differ between MDD-VR and MDD-W but was lower in both of these two groups than in HC (both p < 0.001). Group-by-time interactions on EBPM accuracy (F = 4.614, p = 0.031) and CPFQ score (F = 5.754, p = 0.021) were present, whereas no significant group-by-time interaction or group effects were observed for HDRS score (both p > 0.05). After VR intervention, MDD-VR showed an increase in EBPM accuracy (Cohen's d = 1.20 [95% CI: 0.53, 1.86], p = 0.001).

CONCLUSIONS

Our results demonstrated that VR-based WMT could improve EBPM deficits in MDD patients. Large-scale studies of a VR-based WMT program are indicated.

Behavioral intention of mental health practitioners toward the adoption of virtual humans in affect recognition training

This paper explores the key factors influencing mental health professionals' behavioral intention to adopt virtual humans as a means of affect recognition training. Therapies targeting social cognition deficits are in high demand given that these deficits are related to a loss of functioning and quality of life in several neuropsychiatric conditions such as schizophrenia, autism spectrum disorders, affective disorders, and acquired brain injury. Therefore, developing new therapies would greatly improve the quality of life of this large cohort of patients. A questionnaire based on the second revision of the Unified Theory of Acceptance and Use of Technology (UTAUT2) questionnaire was used for this study. One hundred and twenty-four mental health professionals responded to the questionnaire after viewing a video presentation of the system. The results confirmed that mental health professionals showed a positive intention to use virtual reality tools to train affect recognition, as they allow manipulation of social interaction with patients. Further studies should be conducted with therapists from other countries to reach more conclusions.

Virtual Reality Therapy for the Negative Symptoms of Schizophrenia (V-NeST): A pilot randomised feasibility trial

BACKGROUND

Negative symptoms are typically observed in people with schizophrenia and indicate a loss or reduction of normal function (e.g. reduced motivation and affect display). Despite obstructing people's recovery, intervention development has received limited attention. This study tests the feasibility and acceptability of a novel Virtual Reality Supported Therapy for the Negative Symptoms of Schizophrenia (V-NeST).

METHOD

A single (rater) blind randomised study with two conditions; V-NeST plus treatment as-usual (TAU) vs. TAU alone, recruiting people with schizophrenia experiencing debilitating negative symptoms. Assessment was at baseline and 3-month post-randomisation. The pre-specified primary outcome was participants' goal attainment, secondary outcomes were negative symptoms and functioning. The study assessed feasibility and acceptability parameters including recruitment, eligibility, treatment adherence and retention. Acceptability was also evaluated qualitatively using a post-therapy feedback interview. Explorative therapy effect on outcomes was estimated.

RESULTS

The study recruited to its pre-specified target of 30 participants (15 randomised to V-Nest). Two participants in each trial arm disengaged and did not complete the study. Therapy engagement for those randomised to V-NeST was appropriate and research procedures were feasible. The experience with therapy and VR was described as positive and useful. Preliminary analysis suggested the therapy may have a large effect on participants goals and a possible effect on negative symptoms.

CONCLUSION

V-NeST is a feasible and acceptable intervention. This therapy has the potential to support people with schizophrenia achieving their recovery goals and may reduce negative symptoms. The efficacy results need to be evaluated in an appropriately powered efficacy study.

The CHALLENGE trial: the effects of a virtual reality-assisted exposure therapy for persistent auditory hallucinations versus supportive counselling in people with psychosis: study protocol for a randomised clinical trial

Background

Many patients suffering from schizophrenia spectrum disorders continue having distressing auditory hallucinations in spite of treatment with antipsychotic medication. The aim of this trial is to examine the effect of a targeted virtual reality therapy for persistent auditory hallucinations in individuals with psychosis. The trial explores whether this type of therapy can decrease the severity, frequency and distress of auditory hallucinations and, additionally, whether it can reduce clinical symptoms and enhance daily functioning in individuals with psychosis.

Methods

The study is a randomised, assessor-blinded parallel-group superiority clinical trial, allocating a total of 266 patients to either the experimental intervention or supportive counselling. The participants will be randomised to either (1) seven sessions of virtual reality therapy or (2) seven sessions of supportive counselling to be delivered within the first 12 weeks after inclusion in the study. All participants will be assessed at baseline and 12 and 24 weeks post-baseline. Independent assessors blinded to the treatment allocation will evaluate the outcome. The primary outcome is the level of auditory hallucinations measured with the Psychotic Symptoms Rating Scales (PSYRATS-AH) total score at the cessation of treatment at 12 weeks. Secondary outcomes are frequency of auditory hallucinations, the distress caused by auditory hallucinations, perceived voice power, patient acceptance of voices, patients’ ability to respond to voices in an assertive way and social and daily function.

Discussion

Promising evidence of the efficacy of this immersive virtual reality-based therapy for auditory hallucinations exist, but evidence needs to be established in a large, methodological rigorous trial. If the therapy proves to be beneficial in reducing the severity of refractory auditory hallucinations, a large group of patients with schizophrenia and related disorders could be the target group of this short-term psychotherapeutic intervention.

Enhancing future-directed thinking in people with first-episode psychosis using a guided imagery intervention

BACKGROUND AND OBJECTIVES

Future-directed thinking (FDT) is associated with goal directed behaviour and may differ in people with psychosis compared to non-clinical controls. This study investigated whether guided imagery could enhance positive FDT in people with psychosis.

METHOD

Participants were 44 people experiencing a first episode of psychosis. They were assessed for negative and positive symptoms, FDT on the Future Thinking Task (FTT), depression, anxiety, autobiographical memory, verbal fluency and spontaneous use of imagery. They were randomised to either a positive or neutral imagery condition, before being retested on the FTT. Outcomes on the FTT were number of events generated, anticipated likelihood, anticipated affect and a composite score.

RESULTS

Participants in the positive imagery condition generated significantly more positive events on the FTT compared with those in the neutral (F (1, 42) = 19.916, p < .001, η_p² = 0.322). In both imagery conditions, likelihood ratings of positive events increased post-intervention. Positive and negative events were both perceived as less likely to occur the further into the future they were, and positive events were anticipated to be more positive and negative events more negative, the further into the future they were.

LIMITATIONS

The participants in this study experienced relatively low levels of symptoms, and therefore caution should be used when applying these results to people with greater symptomatology.

CONCLUSIONS

Positive guided imagery shows promise for enhancing positive FDT in people with first-episode psychosis. This intervention may offer a simple and effective method of enhancing engagement with the future, with potential implications for goal-directed behaviour.
