This article focuses on the new model for prescribing psychotherapy provided by psychologists that has been in effect in Switzerland since July 1, 2022. Psychologists can now practice as independent providers with a prescription from a primary care physician for a given number of sessions. This new law, which should facilitate access to mental health care, introduces new administrative issues for general practitioners and transforms their relationship with their patients and psychologists. This phenomenon is part of a broader system of care that is changing and requires a great deal of adaptation on the part of front-line workers. Close collaboration between prescribing physicians, psychologists, psychiatrists and patients is therefore essential.
