Over 28% of people with epilepsy (PwE) struggle from at least one anxiety disorder, making anxiety the most common psychiatric comorbidity in this population. Despite the importance of treating anxiety in PwE, it has not received much research attention and is often unrecognized and untreated. Research has suggested that including exposure therapy (ET) as a part of an anxiety treatment may be helpful for decreasing anxiety in PwE. Research has also shown that Virtual Reality (VR) is an effective and helpful tool for delivering ET in a number of different types of anxiety disorders, such as posttraumatic stress disorder, panic disorder, and social anxiety disorder.
To the investigators' knowledge, no research has been conducted to-date on using VR to deliver ET (VR-ET) in PwE. People with epilepsy have commonly been excluded from VR studies due to the concern that it may trigger seizures in people with photosensitive epilepsy. Although limited research is available on the use of VR in PwE, hesitations regarding the use of VR in this population have not been substantiated and clinicians and researchers are increasingly considering VR for use in this population.
The use of an immersive VR head-mounted display to deliver ET in this population offers several benefits. For example, studies suggest that VR-ET is an especially useful method for customized treatment when it is not safe or practical to do exposures. This is important to consider as it may not be practical to do exposures in-person during times of pandemic, such as the COVID-19 pandemic. Even outside of the pandemic, VR reduces the need for travel, which is difficult for PwE in normal circumstances as driver's licences are typically suspended after a confirmed seizure. Using VR for ET as opposed to traditional ET can also save money and time, and allow for more equitable access to healthcare resources for those who may not live in urban centers.
The investigators designed and will be rigorously evaluating a VR-ET program administered in private residences specific for PwE that focuses on decreasing anxiety that is specifically related to their epilepsy or seizures. This study would be among the first to evaluate VR-ET in this population. This study will also contribute to the limited body of research that currently exists managing comorbid anxiety in PwE as well as the minimal existing literature about fears specifically related to epilepsy or seizures.
The overall primary objective of this study is to report on the feasibility and appropriateness of the protocol and evaluation instruments for use in the subsequent larger clinical trial. The secondary objective is to evaluate whether VR-ET reduces epilepsy- or seizure-related anxiety in PwE. It is hypothesized that PwE will experience decreased levels of epilepsy-related anxiety after undergoing VR-ET. These findings will be used to inform a future randomized controlled trial.

Experimental: Participants Receiving VR-Exposure Therapy Treatment
All participants will be receiving the experimental VR-exposure therapy treatment.
Device: Participants Receiving VR-Exposure Therapy Treatment
In the baseline interview with an exposure therapy specialist and a member of the research team, participants will be presented with approximately three sets of possible exposure scenarios, each associated with approximately three different scenes that increase in severity level. Through discussion with the exposure therapy specialist, the participant will choose the exposure scenario (out of the three options) that most closely resembles their own epilepsy- or seizure-related fears. As the treatment, the participant will be exposed to the scenes that are associated with their chosen exposure set in a hierarchical manner using an immersive head-mounted display. The participant will work through the three levels of the chosen exposure scenario for approximately two weeks, ideally on each level for four days.
- Change in baseline scores using the Epilepsy Anxiety Survey Instrument (EASI) [ Time Frame: Baseline and post-intervention (i.e., one week after completing the VR-ET intervention) ]
The EASI is validated for assessing epilepsy-related anxiety features and severity. The EASI is an 18-item questionnaire and employs a 4-point scale ranging from 0 to 3. Scores range from 0 to 54, where higher scores suggest more severe anxiety.
Note that by using the EASI, the investigators are simultaneously using the brEASI (brief Epilepsy Anxiety Survey Instrument), which is a validated screening tool for anxiety disorders in PwE. The brEASI is made up of eight items that are already asked in the EASI, also employing a 4-point scale ranging from 0 to 3. Scores range from 0 to 24, where a score greater than or equal to 7 suggests that the participant likely has an anxiety disorder.
- Change in baseline scores using the Perceived Stress Scale (PSS) [ Time Frame: Baseline and post-intervention (i.e., one week after completing the VR-ET intervention) ]The PSS assesses how one perceives their own stress levels. The PSS is a 14-item questionnaire and employs a 5-point scale with a range of 0 to 4. Scores range from 0 to 56. Higher scores indicate greater perceived stress levels.
- Feasibility and appropriateness of the study procedures and evaluation instruments [ Time Frame: One week after completing the VR-ET intervention ]Questions during a semi-structured interview at T2 will assess opinions on the device and VR-therapy program experience including: (1) Ease of using the device; (2) Participants' experience with learning how to use the device; (3) Realism of the 360-degree videos; (4) Subjective remarks on whether or not they experience less fear about the scenario that they were exposed to and their avoidance behaviours in relation to that scenario over the past week in the real world; (5) Subjective remarks on how their epilepsy- or seizure- related anxiety in general compares to before they started the VR-exposure therapy program; (5) Aspects of the program that they thought were particularly helpful or unhelpful; and (6) Experience completing the exposure over a video-call with a member of the research team from their home.
- Anxiety levels after each VR-exposure therapy session [ Time Frame: Each day of the VR-ET intervention (approximately two weeks) ]
Participants will fill out the "Subjective Units of Distress Survey" (SUDS) at the following time points each day in the program that an exposure is completed:
- Before the exposure
- Immediately after completing the exposure
- Ten minutes after completing the exposure
The SUDS assesses the participant's anxiety levels on a scale of 0-100. The purpose of using the SUDS will be to assess if: the SUDS scores (i.e., levels of anxiety) that are recorded before completing the exposure are lower compared to the SUDS scores that are recorded immediately after completing the exposure; the SUDS scores decrease over the 10-minute post-exposure SUDS; and if participants' overall anxiety progressively decreases over the course of each exposure level.
- Changes in safety-seeking behaviours after completing the VR-ET intervention [ Time Frame: One week after completing the VR-ET intervention ]The investigators will evaluate if participants' responses in the post-intervention interview suggest that they are engaging in less safety-seeking behaviours after completing VR-ET.
