The psychiatric interview aims to establish a therapeutic relationship to collect information, formulate a diagnosis, and develop a treatment plan. It requires establishing trust and open communication while being sensitive to the personal nature of the topics discussed. The interview involves gathering the patient's narrative, conducting a behavioral observation and mental status exam, and obtaining collateral information when possible to understand the patient's history and current state. Building rapport and maintaining an empathic and non-judgmental approach are essential for a successful psychiatric evaluation.
