One of the tools that a case manager might use to assess a client is the Mental Status Exam (MSE). The MSE has several domains. Let's discuss the "Mood and Affect" domain:

A. Mood - a symptom as reported by the individual describing how they feel emotionally, such as: normal, euphoric, elevated, depressed, irritable, anxious, angry.

B. Affect - observed reaction or expressions. The range of affect includes: broad, restricted, blunted, flat, inappropriate, labile, mood-congruent, mood incongruent.
