Conducting a mental status examination

“Conduct mental status examination” (NBCC, 2027 task 2B.5)

The mental status examination (MSE) is a structured description of a client's appearance, behavior and mental functioning at the time of the interview. It is a snapshot, recorded in objective terms, that supports diagnosis and risk assessment. The exam tests MSE categories and how to describe findings accurately.

Key points

Standard categories: appearance, behavior and psychomotor activity, attitude toward the interviewer, speech, mood, affect, thought process, thought content, perception, cognition (orientation, attention, memory), insight and judgment.
Mood is the client's reported emotional state, ideally in their own words; affect is the counselor's observation of emotional expression, described by range, intensity, stability and congruence with mood.
Thought process describes how thoughts are organized (for example linear, tangential, circumstantial, loose associations, flight of ideas); thought content describes what the client thinks about (for example delusions, obsessions, suicidal or homicidal ideation).
Perceptual disturbances include hallucinations (perception without stimulus) and illusions (misinterpretation of a real stimulus).
Orientation is commonly assessed to person, place, time and situation.
Describe observations objectively, for example 'speech rapid and pressured, difficult to interrupt' rather than 'manic speech'.
The MSE reflects one point in time and should be repeated when the client's state changes.

In practice

A counselor records: 'Client appeared disheveled, wearing the same clothing as last week. Psychomotor slowing. Speech soft and slow. Mood described as "empty". Affect constricted and congruent. Thought process linear. Denies suicidal ideation. Oriented to person, place, time and situation. Insight fair, judgment fair.'

A client jumps rapidly between topics linked only by rhymes and talks over the counselor. The counselor notes flight of ideas and pressured speech, and assesses sleep and risk because of the possibility of a manic episode.

What is the difference between mood and affect on the MSE?

Mood is the client's self-reported emotional state, while affect is the counselor's observation of emotional expression.

Is a delusion recorded under thought process or thought content?

Thought content, because it concerns what the client believes rather than how thoughts are organized.

Why describe MSE findings in observable terms rather than labels?

Objective descriptions are more accurate, defensible and useful to other providers than diagnostic labels.
