AF-ekt (stress on the first syllable) noun

What it means

What others can see of a person's feelings. Mood is how the person says they feel; affect is what the nurse observes. Affect is described as appropriate or inappropriate to the situation, and by its range: broad, restricted, blunted or flat (almost no expression), or labile (changing quickly). In everyday English, "affect" is usually a verb meaning to influence, said with the stress on the second syllable.

For the nurse

Describe the affect in a mental status exam, and note whether it matches what the client says. "Says she is fine, affect flat, poor eye contact" is a useful note.

In a chart

"Affect flat; speech slow and soft; reports mood as 'empty.'"
