Facial Affective Scale

**Semantic type:** Intellectual Product

**Definition:** A pain measurement tool that uses drawn representations of cartoon faces (of the "smiley face" variety) that range from frowning and grimacing to smiling heartily. These scales can be used objectively by the practitioner or a family member to evaluate the pain expression on the patient's face, or subjectively by having the patient point to the representation that most closely resembles his or her current level of pain. This scale is often used in pediatrics and geriatrics.

**Synonyms:** - FAS - Faces Scale
