Most patients treated by psychiatrists are often ambivalent about their treatment and are unlikely to have a stable desire to be treated. For such patients, "desire formation support" reported by Koichiro Kokubun is considered necessary for the preliminary stage of "supported decision making", and it is the responsibility of the therapist. Open Dialogue (OD), a method/system/thought of dialogical practice developed in Finland, involves the entire process of restoration of the patient's subjectivity through dialogue, the discovery of his or her own desires, and making decisions. It is considered inadvisable to actively show the treatment plan to the patient, and arguing, persuading, interrogating, and advising are inappropriate for OD. These behaviors suppress the patient's autonomy and "disempower" them. In contrast, the seven principles of OD are those for respecting the patient's autonomy, initiative, or desire. It is important in OD practice to be flexible and responsive to patients'needs, and to engage in their social network restoratively.
 In a safe and secure environment, we should listen to patients and their families, and respond to them through dialogical practice. Many voices are derived, creating a polyphonic space where no opinion is denied. If the patient's autonomy and subjectivity are restored in such a space, they will be led to the formation of desires. By carefully working together in the process up to this point, the patient's decision making will become automatic.
