Arm && Interventions

Group	Intervention	Description
Sham VeNS	Sham VeNS Device	The sham device looks identical to the active device and interacts with the app in a similar manner to the active device. The device will be placed on the head in a manner analogous to headphones with hydrogel electrodes placed over the mastoid processes. Participants will be advised to use the device at home for 30 minutes per day.
Active VeNS	Active VeNS Device	The active device utilizes a technology termed vestibular nerve stimulation (VeNS). The device will be placed on the head in a manner analogous to headphones and will deliver a small electrical current to the skin behind the ears, over the mastoid processes. Participants will be advised to use the device at home for 30 minutes per day.

Primary Outcome Measures

Name	Time	Method
Hamilton Depression Rating Scale (HDRS-17)	6 weeks	The HDRS (also known as the HAM-D) is the most widely used clinician-administered depression assessment scale. The original version contains 17 items (HDRS-17) pertaining to symptoms of depression experienced over the past week. Scoring is based on the 17-item scale and scores of 0-7 are considered as being normal, 8-16 suggest mild depression, 17-23 moderate depression and scores over 24 are indicative of severe depression; the maximum score being 52 on the 17-point scale. The HDRS-17 scoring shall be the Primary Outcome of the study and will be completed at baseline and each study visit. The proportion (%) of participants achieving the HDRS-17 minimal clinically important difference (≥3 point reduction) by the 6-week time point between the active and sham groups.

Secondary Outcome Measures

Name	Time	Method
Hamilton Depression Rating Scale (HDRS-17)	Change in score at 4 week post-intervention timepoint	The HDRS (also known as the HAM-D) is the most widely used clinician-administered depression assessment scale. The original version contains 17 items (HDRS-17) pertaining to symptoms of depression experienced over the past week. Scoring is based on the 17-item scale and scores of 0-7 are considered as being normal, 8-16 suggest mild depression, 17-23 moderate depression and scores over 24 are indicative of severe depression; the maximum score being 52 on the 17-point scale.
Quality of Life (EQ-5D-5L)	Change in score from baseline to 6 weeks	The EQ-5D-5L is a self-assessed, health related, quality of life questionnaire. The scale measures quality of life on a 5-component scale including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each level is rated on scale that describes the degree of problems in that area. The tool also has an overall health scale where the rater selects a number between 1-100 to describe the condition of their health, 100 being the best imaginable. The EQ-5L-5D shall be completed at baseline and at 6 weeks. The EQ-5L-5D has previously been tested for reliability and validity.
WHO Disability Assessment Schedule 2.0 (WHODAS2)	Change in score at 4 week post-intervention timepoint	The WHO Disability Assessment Schedule 2.0 is a standardized assessment tool developed by the World Health Organization (WHO) to measure general health, disability levels and impairment across various domains of functioning, including mental and neurological disorders. It is designed to assess the impact of health conditions and disabilities on an individual's ability to participate in various life activities. The WHODAS 2.0 shall be a secondary outcome of this study, and will be completed at the baseline visit and repeated at each visit
Insomnia Severity Index (ISI)	Change in score from baseline to 6 weeks	The Insomnia Severity Index (ISI) is a validated short, self-report screening assessment tool designed to evaluate insomnia by measuring an individual's perception of both day and night symptoms of insomnia. The Index consists of seven items which are each assessed in terms of perceived difficulty: falling sleep, staying asleep, and time of awakening, satisfaction with current sleep pattern, interference with daily functioning, noticeability by others of impact of lack of sleep, and degree of perceived distress or concern caused by the sleep problem. The ISI shall be a secondary outcome of the study and be completed at baseline and 6 weeks.
