Which domain of the mental status examination assesses outwardly observable emotional reactions?

• A. Appearance
• B. Affect
• C. Mood
• D. Speech

Answer: (B)

The main idea here is understanding how the clinician notes emotional expression during the mental status exam. Outwardly observable emotional reactions are known as affect. It’s what you can see and hear in a person’s facial expressions, eye contact, voice tone, and overall responsiveness as they express emotions. Clinicians describe affect along dimensions like range (full vs. restricted), intensity, and whether it’s appropriate or congruent with what the person says they feel. For example, a person might describe sadness but show a flat, constricted affect, or laugh inappropriately in a serious moment.

Mood, by contrast, is the person’s subjective emotional state as they report it, not what is visibly displayed. Appearance refers to how the person looks and presents themselves, including grooming and clothing, not their emotional expression. Speech pertains to how they talk—rate, volume, fluency—not the actual emotional display. So the domain that specifically captures outward emotional reactions is affect.
