evaluation of the concordance between measures obtained by a medical device for emotional monitoring (emocare) and the patient health questionnaire (phq-9) score in patients with mild to moderate depressive episode

Conditions: Major Depressive Disorder (MDD)

Summary: the aim of this clinical investigation is to find out whether the emocare emotional monitoring software provides consistent results compared with the tools available for assessing the emotional state of patients suffering from mild to moderately severe depressive episod. it will also provide information on how patients feel about the use of passive monitoring software (without the active involvement of patient). the main questions it aims to answer are as follows: does emocare provide consistent results compared with tools already used in current practice? what are the medical problems encountered by participants when using emocare? the researchers will compare emcocare to various questionnaires usually used in the management of patients suffering from depression (phq-9, madrs, gad-7, bdi-ii, eq-5d-5l). participants who agree to take part in the study, during a selection visit, will be able to: 1. install the software on a digital interface (smartphone, computer, etc.) and activate or deactivate it whenever they wish during the 6-week follow-up period. 2. attend 2 scheduled appointments at the centre (a first appointment then a second 6 weeks later) to complete a series of questionnaires, being questioned by the doctor, and fill in other questionnaires on their own. 3. at home, answer questionnaires independently, 2 weeks and 4 weeks after the first appointment. 4. receive a telephone call from the doctor 3 weeks after the first appointment to find out how the participants are feeling. 5. keep a diary with the symptoms they have experienced, any medical consultations they have made, or changes in drug treatment.
