Full Definition
In psychiatric terminology, affect refers to the externally observable emotional state of a patient as assessed by the clinician during examination. It encompasses facial expressions, tone of voice, body language, and overall emotional presentation. Affect is distinguished from mood, which is the patient's subjective internal emotional state. Common descriptors include flat, blunted, restricted, labile, appropriate, or inappropriate affect. Assessment of affect is a crucial component of the mental status examination and helps inform diagnostic and treatment decisions.
