VR-KET: Using Virtual Reality to Control the Audio-visual Inputs During Ketamine/Esketamine Treatment
Study Details
Study Description
Brief Summary
Investigators aim to examine the role of audiovisual inputs during treatment with ketamine/esketamine in affecting tolerability and effectiveness of treatment of depressive episodes, by providing patients with a relaxing environment using virtual reality goggles and noise cancelling headphones, and assessing whether these tools can improve the tolerability and effectiveness of treatment with ketamine/esketamine

Outcome Measures
Primary Outcome Measures
- Tolerability of VR treatment assessed by qualitative report [baseline and Immediately post-VR treatment]
Tolerability of VR treatment will be assessed by qualitative report, an open-ended question where the participant is allowed to describe any concerns not covered by SAFTEE assessment.
- Safety of VR treatment assessed by Systematic Assessment of Treatment Emergent Events (SAFTEE) assessment [baseline, during VR treatment and Immediately post-VR treatment]
The SAFTEE assessment will be used to assess adverse events during the trial by the number of participants that had any adverse events while on study.
- Change in overall treatment experience satisfaction between the pre-VR and VR treatment sessions [Baseline and immediately post VR treatment session]
Efficacy will be assessed by the difference in overall treatment experience satisfaction (via Likert scale) between the pre-VR and VR treatment sessions. Total scores range from 0 to 10 with higher scores indicating higher satisfaction with the treatment experience.
Secondary Outcome Measures
- Change in 5-Dimensional Altered States of Consciousness Questionnaire (5D-ASC) subscale scores [baseline, during VR treatment and Immediately post-VR treatment]
The 5D-ASC measures altered states of consciousness and contains 94 items using visual analogue scales. Score for each will be calculated from 0 to 100 based on measurement of where the participant has drawn the line. Then each subscale is the median score from a pre-defined list of items (eg subscale 2 is median of items 9,81,94). Higher scores means more altered state of consciousness.
- Change in 5D-ASC total score [baseline, during VR treatment and Immediately post-VR treatment]
The 5D-ASC measures altered states of consciousness and contains 94 items (visual analogue scales. Score for each will be calculated from 0 to 100 based on measurement of where the participant has drawn the line. Total score is the median of all items. Higher scores means more altered state of consciousness.
- Change in The Clinician-Administered Dissociative States Scale (CADSS) [baseline, 40 minutes and immediately post VR treatment]
The CADSS is a 23 item structured clinical interview to assess state dissociation rated by clinicians. Each item is scored from 0 (not at all) to 4 (extreme). Total score range from 0-92 with higher scores indicating greater severity of dissociative experiences.
- Change in participant experience [baseline, during VR treatment and Immediately post-VR treatment]
Participant experience will be assessed by self report on whether it was a "pleasant vs unpleasant experience"using a Likert scale. Scores from 0-11 with higher scores indicating a more pleasant experience.
- Change in level of relaxation [baseline, during VR treatment and Immediately post-VR treatment]
The "level of relaxation" will be scored using a Likert scale with total score range from 0 to 11. Higher scores indicate a higher level of relaxation.
