This document outlines the components of a psychiatric history taking. It includes gathering demographic data, chief complaints, history of presenting issues, past psychiatric and medical history, family history, substance use, social circumstances, personal history, and assessment of premorbid personality. The goal is to obtain a holistic understanding of the patient's condition, including precipitating stressors, through interviews of the patient and other informants while establishing rapport. Thorough evaluation of personal and family history helps identify any prior conditions or vulnerabilities.
