Mental health disorders, with a 30% annual prevalence rate, are a leading cause of disability and reduced life expectancy. Despite their impact, patient-reported experience measures (PREMs) and outcome measures (PROMs) are underutilized in psychiatry. MonPsy&Moi®, a digital platform funded by ATIH and DGOS, addresses this gap by providing a user-friendly tool to assess patient experiences and outcomes in real-time, aiming to improve the quality of psychiatric care across France.

The study consists of two stages:

Stage 1 (No Feedback): MonPsy&Moi® is deployed across 12 psychiatric facilities, collecting patient data without feedback to clinicians. Objectives include assessing implementation feasibility, validating adaptive questionnaires (PREMIUM), and identifying predictors of patient outcomes, such as relapse and healthcare utilization.

Stage 2 (With Feedback): Focuses on patients with severe mental illnesses (schizophrenia, bipolar disorders, and major depressive disorders). This stage evaluates the impact of providing PREMs/PROMs feedback to clinicians on relapse rates, healthcare costs, and overall patient outcomes.

MonPsy&Moi® uses adaptive questionnaires tailored to psychiatric care, covering key domains such as dignity, information, interpersonal relationships, care environment, and treatment. It also evaluates health-related quality of life, including psychological well-being, autonomy, self-esteem, and social relationships. The platform integrates with national healthcare databases (SNDS) to enhance data analysis and predict patient trajectories.

The study will involve over 22,000 participants in Stage 1 and 1,100 participants in Stage 2, using a quasi-experimental design to compare feedback and non-feedback strategies. Results aim to demonstrate the feasibility, acceptability, and efficacy of MonPsy&Moi® in improving mental health outcomes and guiding national psychiatric care policies.

By empowering patients and clinicians with actionable insights, MonPsy&Moi® aspires to set a new standard for patient-centered mental healthcare in real-world settings
