(b) A “patient” is a person who consults, or is interviewed by, a psychotherapist for purposes of diagnosis or treatment of a mental or emotional condition, including alcoholism and other drug addiction.

1. Those persons present to further the interest of the patient in the consultation, examination, or interview.
2. Those persons necessary for the transmission of the communication.
3. Those persons who are participating in the diagnosis and treatment under the direction of the psychotherapist.
(2) A patient has a privilege to refuse to disclose, and to prevent any other person from disclosing, confidential communications or records made for the purpose of diagnosis or treatment of the patient’s mental or emotional condition, including alcoholism and other drug addiction, between the patient and the psychotherapist, or persons who are participating in the diagnosis or treatment under the direction of the psychotherapist.
