Participants: Clinical staff affiliated within South London and Maudsley NHS Trust (SLaM) and working in inpatient and outpatient mental health settings will be recruited. The investigators anticipate recruiting 20-25 participants to the study. This number is based on recruiting a big-enough sample to assess the feasibility of the study and of the resources available.

Procedure: The study will be advertised to prospective participants via a general email to staff via the clinical team leader and email circulars. Posters will be displayed in staff rooms with a request that anyone interested in taking part contact the research team. Staff who display an interest in the study will be emailed a participant information sheet with study details. Once participants have provided online written informed consent to take part, they will be asked to undergo baseline assessments. Baseline assessments will be conducted online using Qualtrics and include: a socio-demographic questionnaire (age, gender, ethnicity, occupation, clinical setting, years of experience, highest level of education), measures of stress, worry, sleep, and burnout. All together, the baseline assessments will take approximately 15 mins to complete.

Following completion of baseline measures, participants will undergo a 5-week course of 20-min sessions of VR relaxation. The VR device used will be the Oculus Quest wireless head mounted display (HMD) with two handheld controllers. The HMD and software have been provided by a Germany based company called Magic Horizons. Participants will be asked to wear the HMD and will wear headphones to hear audio. Each session will involve participants experiencing two virtual environments designed to promote relaxation, at least one of which will have a small interactive component to aid engagement. Environments will focus on nature and will be paired with soothing music or guided meditation. For example, scenes might include dolphins dancing underwater, a beach with rock pools, waterfalls, a rainforest, green meadows with flowers, mountains with lakes and/or a sandy desert. Participants will be seated throughout all sessions. Sessions and assessments will be scheduled in working hours around the participant's clinical duties.

Before and after each session participants will be asked to complete state-measures of psychological wellbeing, and they will be asked to rate satisfaction with each session at session completion and complete a measure of sense of presence. Following completion of the 5-week VR relaxation course, participants will repeat baseline measures of stress, worry, burnout and sleep. Participants who drop out of the intervention will be invited to complete these measures providing they attend a minimum of one VR session. The investigators endeavour to complete pre-assessment measures within one week prior to the first VR session and end of intervention measures within one-week of participants finishing the course of VR. Study measures will be presented using the online survey platform Qualtrics. Participants will enter data independently with a member of the research time present to assist.

Follow-up Qualitative Interviews: Participants will be invited to participate in follow-up interviews and feedback regarding their experiences of the VR relaxation intervention will be sought. It is expected that 20 participants will attend a follow-up interview. Each interview will take approximately 30 minutes to complete. A series of simple open-ended questions will be asked, and participants will answer verbally. The questions will address staff's opinions regarding the acceptability and feasibility of conducting VR relaxation sessions in the workplace, aspects they enjoyed and barriers to implementation. An audio-recording will record responses to these questions when permission has been granted. The qualitative data gained from these questions will be analysed using thematic analysis to understand the main themes.
