The goal of this clinical trial is to determine the acceptability, feasibility, and validity of the bWell Cognitive Care Platform for Depression (bWell-D), a novel Virtual Reality (VR) cognitive assessment and remediation tool, in depressed populations. The main questions are: * Do patients with Major Depressive Disorder (MDD) find the bWell-D cognitive assessment battery and protocol feasible, tolerable, and acceptable? * Do patients with Major Depressive Disorder (MDD) find the 8 week bWell-D remediation protocol feasible, tolerable, and acceptable? Following initial cognitive assessment, researchers will assess feasibility outcomes in the bWell remediation arm to a VR scenes experience arm to learn more about the feasibility of bWell for cognitive assessment and remediation. Patients will: * Complete an initial bWell cognitive assessment session * Randomized to either receive bWell cognitive remediation or a VR scenes experience twice a week for eight weeks * Complete cognitive/functional/clinical assessments and EEG at baseline, midpoint and endpoint of the remediation protocol, as well as measures of tolerability, engagement, and enjoyment
Patients with a diagnosis of major depressive disorder, who are currently either euthymic or mildly depressed, will be recruited for this study. 40 participants (ages 19-55) will be recruited from the community from two outpatient sites and 30 participants will be recruited from an inpatient site. For the outpatient sample, 20 patients will be recruited at University of British Columbia (UBC) and 20 patients will be recruited at Simon Fraser University (SFU), and for the inpatient sample, 30 patients will be recruited in collaboration with the John Volken Academy (JVA). Patients will complete an initial virtual assessment to assess eligibility, after which patients will complete the bWell cognitive assessment session. This session will include rating scales for current symptoms of depression/anxiety, subjective cognitive functioning, global/occupational functioning and a validated computerized neuropsychological test battery to assess objective cognitive functioning. Participants will complete a brief VR training session with the VR equipment. Subsequently, the bWell cognitive assessment program will be administered, followed by scales assessing tolerability and enjoyability/engagement. Patients will then be randomized in a 1:1 ratio to receive bWell cognitive remediation or to a control group in which they passively experience various VR scenes. Randomization will occur separately in inpatient and outpatient groups. Patients are told that either method is hypothesized to have effects on their cognition and are therefore blinded to whether they are in the 'active' treatment group. Assessors for outcomes that are not self-reported or self-administered will also be blinded to group assignment. Participants randomized to the bWell cognitive remediation program will complete 40-minute remediation sessions using bWell twice a week for 8 weeks; the other group will view VR scenes in bWell without any instructed cognitive tasks. EEG recordings will be administered at baseline, at midpoint, and after completing the 8 weeks. At the end of the 8 weeks, measures of subjective cognitive functioning, global/occupational functioning and the computerized objective cognitive testing battery will also be repeated. Patients will also complete tolerability and enjoyment/engagement scales during the remediation procedure. Patients will be debriefed at the end of their participation about their treatment groups.

Patients will take part in the bWell cognitive remediation protocol, consisting of 40-minute sessions of bWell, administered 2 times a week for 8 weeks. These sessions consist of tasks that target various cognitive domains and increase in complexity and difficulty as training progresses. The tasks are as follows: 1. Lab Exercise: participant alternates between two different, increasingly complex 'recipes', targeting executive functioning and divided attention. 2. Egg Exercise: In an office environment, participants must seek out and maintain their gaze on certain objects in order to collect them in the presence of visual distractors, targeting sustained attention. 3. Mole Exercise: participants must strike moles with the matching coloured hammer as fast as possible, targeting selective attention. 4. Theatre Exercise: participants must remember objects presented on stage and recreate the sequence after the curtains close, targeting working memory.
Patients will take part in the viewing of VR scenes which contain no instructed cognitive tasks. This consists of 40-minute sessions of viewing VR scenes, administered 2 times a week for 8 weeks.
Recruitment rates
Measured separately in inpatient and outpatient settings, target of 2/month total from both sites. Will be assessed every 6 months and appropriate action taken if target not met.
Time frame: 8 weeks
Session completion rates
Measured separately in inpatient and outpatient settings, target of 80% completion of all studies. Will be assessed after the 5th and 10th participants to complete bWell-D assessment and mid-point of bWell-D remediation, with appropriate action taken if not met.
Time frame: 8 weeks
Study drop out rates
Measured separately in inpatient and outpatient settings, target 20% or less participant dropouts. Will be assessed after the 5th and 10th participants to complete bWell-D assessment and mid-point of bWell-D remediation, with appropriate action taken if not met.
Time frame: 8 weeks
Change in cognitive functioning in active vs. control groups
Assessed using the Neurocognitive Index (NCI) score generated by the Central Nervous System Vital Signs (CNS-VS), an index of global cognitive functioning
Time frame: 8 weeks
Change in global psychosocial functioning in active vs. control groups
Assessed through self-report using the Sheehan Disability Scale (SDS) and Quality of Life Enjoyment and Satisfaction Questionnaire. When self-reporting scores on the SDS, patients are asked to rank on a 10-point scale the level of disruption they have experienced at work/school, in their social life and home responsibilities over the past week. Total scores range from a minimum of 0 to a maximum of 30, where higher scores represent increased functional impairment.
Time frame: 8 weeks
Change in individual cognitive domains in active vs. control groups
Assessed via the individual domain scores generated by the CNS-VS computerized battery
Time frame: 8 weeks
Change in subjective perceived cognitive functioning in active vs. control groups
Assessed via the Perceived Deficits Questionnaire for Depression (PDQ-D), a self-report scale assessing patients' perceived functioning in four domains: attention/concentration, planning/organization, retrospective memory and prospective memory. Total score ranges from 0 to 80, where higher scores represent increased cognitive impairment.
Time frame: 8 weeks
Measure of video game satisfaction/enjoyability of bWell-D remediation in active vs. control groups
Assessed using the The Game User Experience Satisfaction Scale-18 (GUESS-18). Total score ranges from a minimum value of 9 to a maximum value of 63, where higher scores represent increased satisfaction.
Time frame: 8 weeks
Change in occupational psychosocial functioning in active vs. control groups
Assessed through self-report using the Lam Employment Absence and Productivity Scale (LEAPS). When self-reporting on LEAPS, patients rate the degree to which problems with low energy/motivation, anxiety/irritability, poor concentration, decreased productivity/mistakes and interpersonal problems have impacted their occupational performance over the past 2 weeks. Total scores range from a minimum of 0 to a maximum of 28, where higher total scores represent increasingly impaired professional functioning.
Time frame: 8 weeks
Change in subjective everyday cognitive functioning in active vs. control groups
Assessed via the Cognitive Failures Questionnaire (CFQ), which assesses lapses of attention, perception and memory in real-life. Total score ranges from a minimum of 0 to a maximum of 100, where higher scores represent increased everyday cognitive failures.
Time frame: 8 weeks
Measure of engagement with bWell-D remediation in active vs. control groups
Assessed using the User Engagement Scale (UES). There is a minimum score of 0 and a maximum score of 235.62, where higher scores represent increased engagement.
Time frame: 8 weeks
Measure of tolerability of bWell-D remediation in active vs. control groups
Assessed using Simulator Sickness Questionnaire (SSQ). Patients rate the presence and severity of various symptoms of cybersickness, including nausea and ocular discomfort. There is a minimum score of 4 and a maximum score of 20, where higher scores represent increased simulator sickness.
Time frame: 8 weeks
