Self-management of Stress and Sleep Disturbances With Virtual Reality Relaxation

Study Overview
=================
Brief Summary
-----------------
Stress is a well-established factor in the onset and continuation of burn-out anxiety, mood and psychotic disorders. Furthermore, sleep disturbances predispose and exacerbate mental health symptoms of the condition. In people with mental health problems, higher (social) stress-reactivity and impaired stress-recovery are present which is further aggravated by sleep disturbances and sleep deprivation. Relaxation reduces the stress, which in turn may reduce mental health symptoms, improve daily life functioning and quality of life. The burden of burn-out and psychiatric illness can be decreased by stress-reducing interventions which have been shown to improve quality of life and social and occupational functioning. Although current stress-reducing interventions appear to be efficacious, it must be taken into account that they require mental effort (i.e. attention and concentration of patients) which is often impaired in patients. To bridge this gap, a new e-Health application was developed called VRelax. VRelax is a virtual reality self-management stress-reduction tool (VRelax). This tool requires far less effort than traditional relaxation exercises due to its immersive properties, and has an immediate effect on perceived stress and emotional mental states. In this study, the short-, medium- and long term effect of VRelax + treatment as usual (TAU) compared to TAU and relaxation exercises on symptomatic recovery, level of social functioning, healthcare consumption and societal costs will be investigated.

Detailed Description
-----------------
Once participants consent, they will complete the first assessment (T0). T0 starts with a physical assessment that consist of measuring weight, height, and waist circumference, a blood pressure test and a blood test. Furthermore, they will complete an assessment of physiological parameters during the use of VRelax. Then participants will complete a couple demographic questions, the Symptom Checklist-90-revised (SCL-90-R), the WHO Disability Assessment Schedule (WHO-DAS), the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), the Hamilton Rating Scale for Depression (HRSD), and the Psychotic Symptom Rating Scales (Psyrats). Participants will then be informed to wear to different wearables for two weeks (Empatica E4 and MotionWatch 8). The instruction is to wear the Empatica E4 during the day to measure their Heart Rate (HR), Heart Rate Variability (HRV), and Skin Conductance (SC). The MotionWatch 8 will be worn during the night to measure their sleep. Participants also receive the instruction to complete the following online questionnaires at home: Burn-out Assessment Tool (BAT), Beck Anxiety Inventory (BAI), Inventory of Depressive Symptomatology Self Reported (IDS-SR), Mood Disorder Questionnaire (MDQ), Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI), Manchester Short Assessment of Quality of Life (MANSA), Recovery Assessment Scale - domains and stages (RAS-DS), Treatment Inventory of Costs in Patients (TiC-P), 36-item Short Form Survey (SF-36), and EQ-5D-5L. Participants receive from their healthcare professional either VRelax or relaxation exercises with the instruction to use this for at least 20 minutes a day, at least five days a week, for six weeks. During those six weeks, participants will wear the wearables (Empatica E4 and MotionWatch 8) the first and the last week. After six weeks after the first assessment, participants will complete the second assessment (T1). T1 is identical to T0 plus the System Usability Scale (SUS) for the participants who used VRelax. After 26 weeks after the first assessment, participants will complete the third assessment (T2). T2 consists of SCL-90-R, WHO-DAS, ASSIST, HRSD, Psyrats, BAT, BAI, IDS-SR, MDQ, PSS, PSQI, MANSA, TiC-P, SF-36, and EQ-5D-5L. The fourth and final assessment (T3) is 52 weeks after the first assessment. T3 is identical to T2.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

| Experimental: VRelax<br>Participants will be using Virtual Reality relaxation (VRelax) in addition to treatment as usual | Device: VRelax<br>* Virtual Relaxation relaxation, VRelax, includes a collection of high quality 360° degrees videos of nature environments with 3D audio and interactive elements, created for relaxation, stress-reduction and improving sleep. When activated, the participant can choose specific 360° videos from a menu. The 360° videos include among other things a coral reef with an interactive game element of popping air bubbles, a scuba diving experience with dolphins, a mountain meadow with cows, and a session of Tibetan sound bowls.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Symptom Checklist Scale - 90 - R | The SCL-90-R is used to evaluate a broad range of psychological problems and symptoms of psychopathology during the last week.The SCL-90-R consists of 90 items scored on a five-point Likert scale. | Between T0 and T1 (six weeks) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in burn-out symptoms and stress | The BAT is being used to evaluate the changes in burn-out symptoms and the PSS is being used to evaluate the changes in perceived stress. Both questionnaires have a five-point scale ranging from never to always | Assessment at baseline, six weeks, 26 weeks, and 52 weeks | 
| Changes in anxiety | The BAI is is a self-report measure of anxiety. Each answer is being scored on a scale value of 0 (not at all) to 3 (severly). A higher total score indicate more severe anxiety | Assessment at baseline, six weeks, 26 weeks, and 52 weeks | 
| Changes in health and health-related quality of life | The EQ-5D-5L is tool to measure health and health-related quality of life. The first 25 items of this questionnaires are based on five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The patient is asked to indicate their health status by choosing the most appropriate level: no problems, slight problems, moderate problems, severe problems, and extreme problems. The last question is to indicate their current health status on a scale from 0 to 100. | Assessment at baseline, six weeks, 26 weeks, and 52 weeks | 
| Changes in depression | The HRSD is a structured interview to assess the severity of depression. The HRSD contains 17 items pertaining to symptoms of depression experienced over the past week. The instruction for the researcher is to select the most appropriate answer which charaterizes the participant the best, ranging from absent to clearly present. | Assessment at baseline, six weeks, 26 weeks, and 52 weeks | 
| Changes in self-reported depressive symptoms | The IDS-SR is a 3-item questionnaire measuring depressive symptoms. Each item has four statements that reflect various degrees of symptom severity, scored on a four-point scale from 0 to 3. | Assessment at baseline, six weeks, 26 weeks, and 52 weeks | 
| Changes in mood | The MDQ is standard a 13-item self-report screening questionnaire with two optional questions that assesses symptoms of mania, hypomania, and depression.
