As a part-time psychiatrist, you work fewer than 35 hours per week, though your duties and responsibilities are no different than those of a psychiatrist working full time. You assess the mental health of patients, diagnose mental illnesses if present, and use your assessment to develop a medicinal or behavioral treatment plan. Part-time psychiatrists may work in an office or remotely via phone or video chat, or you may make house calls and hospital visits to patients. If not engaged in patient treatment, you may instead focus on academia and research to locate new treatments or understanding.
