[The principle of secularism and religious practices in psychiatry].

While French legislation guarantees patients' religious freedom and imposes neutrality on professionals, tensions arise in the interpretation of these principles. In psychiatry, religion can provide comfort and support, or be deleterious depending on the context. Caregivers lack scientific knowledge on this subject, which they are reluctant to broach, and have heterogeneous approaches, sometimes perceived as unfair by patients. Patients report a lack of understanding and support, which can affect their relationship with the teams and their mental health. Deploying training and research on these issues would enable us to better support people in their recovery journey.
