Affect

Observable emotional expression and mood state as assessed by clinician during examination.

Full Definition

In clinical documentation, affect refers to the outward, observable expression of emotion, while mood describes the patient's subjective internal emotional state. Affect is described using terms like flat, blunted, restricted, appropriate, inappropriate, labile, or euthymic. This distinction is crucial in psychiatric assessment and differs from the general English usage of 'affect' as a verb meaning to influence.

Usage

Usage note: Clinical term distinct from 'effect'; lowercase unless beginning sentence.
