Identification of Physiological Data by a Wearable Monitor in Subjects Suffering From Major Depression Disorders

Study Overview
=================
Brief Summary
-----------------
To evaluate, over a period of six months, the links between physiological data collected such as electrodermal activity (or Galvanic Skin Response), motor activity measured by accelerometer, heartbeat measured by photoplestimograph and the clinical evaluation performed by the physician, in patients suffering from major depression disorder.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Wearable monitor collected phydiological measurements<br>This is a single arm study with a wearable monitor that collects physiological measures (falling in the categories physical activity, heart rate, heart rate variability, breathing rate and sleep) 24/7 in ambulatory. | Behavioral: Patient follow-up of depression<br>* All patients who agree to participate in the study are diagnosed by their GP/Psychiatrist with a diagnostic assessment instrument called DSM-5. Participants visit their GPs/Psychiatrists at baseline, month 1, month 2, month 3, month 4, month 5 and month 6. At each visit, the GPs/Psychiatrists: assess the depression severity by using MADRS scale assess the severity of illness at time of assessment compared with start of treatment by using CGI-S measures the patient complete the self-administered questionnaire of HAD scale that measures the symptoms of anxiety and depression.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Comparison of change in MADRS ( Montgomery-Asberg Depression Rating Scale) total score with physiological measurements. | Change in central rater Montgomery-Asberg Depression Rating Scale (MADRS) total score and comparison with changes in physiological measurements such as activity, emotional arousal, heart rate, heart rate variability, breathing rate and sleep. The Montgomery-Åsberg Depression Rating Scale (MADRS) is a 10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms. Each of the 10 items is rated on a scale of 0 to 6, with differing descriptors for each item. These individual item scores are added together to form a total score, which can range between 0 (low severity of depressive symptoms) and 60 points (high severity of depressive symptoms), higher score indicating poorer health outcomes. The MADRS provides a measure of the overall level of depression. | Baseline, Month1, Month 2, Month 3, Month 4, Month 5, Month 6 | 
| Comparison of change in HAD (Hospital Anxiety and Depression) total score with physiological measurements. | Change in Hospital Anxiety and Depression total score and comparison with changes in physiological measurements such as activity, emotional arousal, heart rate, heart rate variability, breathing rate and sleep. The Hospital Anxiety and Depression Scale used for measuring anxiety Scored on a scale of 0-21 (higher score more anxiety) and for measuring depression Scored on a scale of 0-21 (higher score more depression). | Baseline, Month1, Month 2, Month 3, Month 4, Month 5, Month 6 | 
| Comparison of change in CGI (Clinical Global Impression) scale with physiological measurements. | Change in CGI scale and comparison with changes in physiological measurements such as activity, emotional arousal, heart rate, heart rate variability, breathing rate and sleep. The Clinical Global Impression Scale (CGI-s), is a widely administered clinician rated scale that assesses the subject overall illness severity and the degree of improvement from the initial assessment. Illness severity is rated on a 1-7 scale where 1 corresponds to Normal, Not at All Ill, 2 is Borderline Mentally Ill, the anchor for 3 is Mildly Ill, the anchor for 4 is Moderately Ill, 5 is Markedly Ill, 6 is Severely Ill, and 7 is Among the Most Extremely Ill Patients.The degree of improvement is rated on a 1-7 scale where 1 corresponds to Very Much Improved, 2 is Much Improved, the anchor for 3 is Minimally Improved, the anchor for 4 is No Change, 5 is Minimally Worse, 6 is Much Worse, and 7 is Very Much Worse. | Baseline, Month1, Month 2, Month 3, Month 4, Month 5, Month 6 |
