An interventional study of Virtual Reality Exposure Therapy in Emotion Regulation Disorders, sponsored by Psychiatric University Hospital, Zurich. Enrolling by invitation at 1 site in Switzerland. Open to participants aged 11 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-16.
Sponsored by Psychiatric University Hospital, Zurich · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to evaluate whether a therapist-guided virtual reality (VR)-based intervention can improve emotion regulation in adolescents receiving inpatient psychiatric treatment. The study will also assess the feasibility, acceptability, and safety of the intervention, as well as explore factors that may predict treatment response.
The main questions it aims to answer are:
Does the VR-based intervention improve emotion regulation compared with a VR relaxation control intervention? Does the intervention reduce sensory sensitivities, anxiety, and related psychological symptoms? Which behavioral, physiological, and speech-based measures are associated with treatment response?
Researchers will compare a personalized VR exposure intervention with a VR relaxation control intervention. Both groups will receive treatment as usual during their inpatient stay.
Participants will:
Be randomly assigned to either the VR exposure or the VR relaxation group. Complete questionnaires, behavioral tasks, and clinical assessments before and after the intervention, with a follow-up assessment approximately three months later.
Participate in weekly therapist-guided VR sessions throughout their inpatient treatment.
Complete additional assessments including speech recordings and standardized behavioral tasks to investigate predictors and mechanisms of treatment response.
Throughout the study, participants will be monitored for adverse events and tolerability of the VR intervention.
This study is a prospective, monocentric, randomized controlled trial evaluating a therapist-guided virtual reality (VR)-based intervention designed to improve emotion regulation in adolescents receiving inpatient psychiatric treatment. Participants will be randomly assigned in a 2:1 ratio to either a personalized VR exposure intervention or a VR relaxation control intervention. Both groups will continue to receive treatment as usual throughout the study period.
The intervention has been developed as an adjunct to standard inpatient care and is tailored to each participant's individual emotional and environmental triggers. Prior to treatment, therapists identify situations that are personally relevant and emotionally challenging for each participant. These situations are then translated into individualized VR session templates based on a standardized library of immersive 360° environments. Throughout the intervention, therapists gradually adjust the intensity and complexity of the exposure according to the participant's progress while maintaining a structured therapeutic framework.
Participants assigned to the control group receive therapist-guided VR relaxation sessions of comparable frequency and duration using immersive natural environments. The control intervention is designed to match the experimental condition with respect to therapist contact, VR exposure, and session length while omitting exposure-based therapeutic components.
Study assessments are conducted at baseline before the intervention, immediately after completion of the intervention, and approximately three months after discharge. Assessments include self-report and caregiver-report questionnaires, standardized behavioral tasks, clinical ratings, and speech-based assessments. In addition to evaluating changes in emotion regulation and related psychological functioning, the study investigates potential predictors and mechanisms of treatment response. These include behavioral performance, physiological responses, eye-tracking measures, and speech characteristics collected during standardized assessment procedures.
Physiological and behavioral data are recorded using non-invasive sensors integrated into the VR system and additional research equipment. Depending on the assessment, these may include heart rate, eye-tracking, head and controller movement, and VR interaction data. Speech recordings obtained during standardized interviews and selected VR scenarios will be analyzed for linguistic and acoustic characteristics. Multimodal data from the same assessment session can be linked using pseudonymized study identifiers and timestamps to investigate relationships between behavioral, physiological, and speech-based measures.
The study will also evaluate the feasibility, acceptability, and safety of implementing personalized VR interventions within an inpatient child and adolescent psychiatric setting. Adverse events, tolerability, session completion, and participant adherence will be documented throughout the intervention. The findings are intended to inform the future implementation and optimization of individualized VR-assisted psychological interventions for adolescents with emotion regulation difficulties across a range of psychiatric diagnoses.

Participants receive individualized therapist-guided virtual reality exposure sessions in addition to treatment as usual (TAU) during their inpatient stay. VR scenarios are selected and adapted according to each participant's individual emotional and environmental triggers using standardized 360° environments. Therapists gradually increase the intensity and complexity of exposure across sessions while applying cognitive behavioral therapy principles. Participants also complete all scheduled study assessments before the intervention, after completion of the intervention, and at follow-up.
Device: Virtual Reality Exposure Therapy
Participants receive treatment as usual (TAU) provided as part of routine inpatient psychiatric care. TAU may include individual psychotherapy, group therapy, pharmacological treatment, occupational and recreational therapy, psychoeducation, and other clinical services according to individual treatment needs. Participants complete the same study assessments as the experimental group at baseline, post-intervention, and follow-up but do not receive the study-specific VR intervention.
The intervention consists of therapist-guided, individualized virtual reality (VR) exposure sessions delivered as an adjunct to treatment as usual during inpatient psychiatric care. Personalized VR scenarios are created using standardized 360° environments based on each participant's individual emotional and environmental triggers. Sessions include graded exposure, with therapists adapting the intensity and complexity of the scenarios according to treatment progress and individual needs. The intervention is delivered several times a week throughout the inpatient stay by trained therapists. The VR intervention is intended to improve emotion regulation by providing repeated, controlled exposure to clinically relevant situations within a safe and structured therapeutic environment.
Questionnaire-based measure assessing emotion regulation skills
The "Selbsteinschätzung Emotionaler Kompetenzen" (SEK-27; Emotion Regulation Skills Questionnaire) is a 27-item self-report questionnaire assessing adaptive emotion-regulation skills. Items are rated from 0 to 4. The mean total score is calculated as the average of all 27 items and ranges from 0 to 4. Higher scores indicate better emotion-regulation skills.

Time frame: From enrollment to the end of treatment at 5-8 weeks.
Change in Speech-in-Noise Perception Accuracy From Baseline to Post-intervention
Speech-in-noise perception is assessed using a computerised task in which participants listen to short sentences presented with auditory noise or competing speech and identify the corresponding number-colour combination. Performance is calculated as the percentage of correctly identified combinations across trials, ranging from 0% to 100%. Higher percentages indicate better speech perception and functional performance under sensory load and are interpreted as a better outcome. Change is calculated as post-intervention accuracy minus baseline accuracy; positive values indicate improvement.
Time frame: From enrollment to the end of treatment at 5-8 weeks.
Change in Differential Threat-Expectancy Ratings During Fear Extinction From Baseline to Post-intervention
Fear learning and extinction are assessed using a computerised conditioning task involving a conditioned threat stimulus (CS+) that is paired with an aversive auditory stimulus during acquisition and a safety stimulus (CS-) that is never paired with the aversive stimulus. Participants rate the expected likelihood of the aversive stimulus following each conditioned stimulus. A differential threat-expectancy score is calculated by subtracting the expectancy rating for the CS- from the expectancy rating for the CS+. Higher positive scores indicate stronger differential threat expectancy. A greater reduction in the differential score during extinction indicates more effective safety updating and is interpreted as a better outcome. Change is calculated by comparing the task-derived differential expectancy measure at baseline and post-intervention.
Time frame: From enrollment to the end of treatment at 5-8 weeks.
Change in Rule-Inference Accuracy on the Object Manipulation Task From Baseline to Post-intervention
Learning under uncertainty and adaptive rule inference are assessed using the Object Manipulation Task. Participants explore and manipulate virtual objects and receive positive or negative feedback based on their actions. Through repeated trials, participants must infer the hidden rules governing successful performance. Rule-inference accuracy is calculated as the percentage of actions that are consistent with the correct hidden rule, ranging from 0% to 100%. Higher percentages indicate more accurate rule inference, more efficient learning, and better behavioural adaptation and are interpreted as a better outcome. Change is calculated as post-intervention accuracy minus baseline accuracy; positive values indicate improvement.
Time frame: From enrollment to the end of treatment at 5-8 weeks.
Change in Speech- and Language-Based Markers Derived From the Emotion Expression Interview From Baseline to Post-intervention
The Emotion Expression Interview is a structured, approximately 15-minute audio-recorded assessment designed to elicit speech relating to emotional processing and emotion regulation. The interview includes neutral speech, sentence reading, open-ended questions about emotions, descriptions of emotionally salient pictures, and sentence-completion prompts. Exploratory measures derived from the recordings include content-based indicators of emotional clarity, emotional insight, and articulated regulation strategies, as well as speech- and language-based features such as pitch, intensity, speech rate, lexical diversity, syntactic complexity, and discourse-level organisation. The measures have different units and ranges, and higher values do not uniformly indicate a better or worse outcome. Changes in the prespecified features from baseline to post-intervention will be examined exploratorily.
Time frame: From enrollment to the end of treatment at 5-8 weeks.
Mean Heart Rate During Virtual Reality Exposure Across the Treatment Period
Heart rate is recorded continuously during virtual reality exposure sessions using a Polar H10 heart-rate sensor. Mean heart rate is calculated in beats per minute for each session and used as an exploratory indicator of autonomic arousal during exposure. Higher values indicate greater physiological arousal but are not inherently interpreted as a better or worse outcome. Changes in mean heart rate across treatment sessions and associations with intervention progress and symptom change will be examined exploratorily.
Time frame: From enrollment to the end of treatment at 5-8 weeks.
