Milieu therapy is a scientific approach to structuring the environment to effect behavioral changes and improve psychological health. It involves manipulating aspects of a client's surroundings, like their hospital experience, to be therapeutic. The goal is for clients to learn adaptive coping skills, interpersonal skills, and stress management techniques that can generalize to other areas of their lives, ultimately achieving autonomy. Nurses play an important role in milieu therapy by helping design therapeutic physical environments, coordinating teams, and facilitating trust-building discussions.
