Mental Status Examination (MSE): Descriptors and Examples
A clinician guide to the mental status examination (MSE) — the domains to cover, descriptor vocabulary, and examples of how to document each.
The mental status examination (MSE) is the psychiatric equivalent of a physical exam: a structured snapshot of a client's mental functioning at a given moment. Documented consistently, it becomes one of the most useful longitudinal tools in a chart, revealing change (or stability) across sessions.
The domains of the MSE
A complete MSE covers roughly the following domains:
- Appearance and behavior: grooming, posture, eye contact, psychomotor activity, cooperation.
- Speech: rate, rhythm, volume, fluency.
- Mood and affect: the client's stated mood versus the observed affect (range, appropriateness, congruence, intensity).
- Thought process: how thoughts are connected (logical, circumstantial, tangential, flight of ideas).
- Thought content: what the thoughts are about (preoccupations, suicidal/homicidal ideation, obsessions, delusions).
- Perception: hallucinations or illusions, in any modality.
- Cognition: orientation, attention, memory, abstraction, judgment.
- Insight and judgment: awareness of illness and the quality of decision-making.
Useful descriptor vocabulary
Precise descriptors make an MSE readable and defensible:
- Affect: full, constricted, blunted, flat, labile; congruent or incongruent with mood.
- Thought process: goal-directed, circumstantial, tangential, perseverative, loose associations.
- Psychomotor: normal, agitated, retarded, with tremor or tics.
Avoid vague terms like "weird" or "fine" — they document nothing useful.
Documenting risk
The MSE is where acute risk is recorded. Always document the presence or absence of suicidal and homicidal ideation, intent, plan, and means, and the protective factors weighed. A suicide risk assessment template keeps this consistent.
Putting it in the note
The MSE fits naturally into the Objective section of a SOAP note or the Data section of a DAP note. Keep it observational rather than interpretive; state what you saw and heard, then offer your formulation separately.
