Mental Status Exam (MSE): A Structured Template Covering Appearance to Judgment

About this tool

The mental status examination (MSE) is the psychological equivalent of the physical exam: a structured, systematic description of a client's presentation at a single point in time. Where the history tells you what the client reports, the MSE documents what you observe and elicit during the interview. It is a core part of assessment, supports diagnosis, establishes a baseline against which change can be measured, and is a standard component of clinical documentation.

The exam covers a consistent set of domains. Appearance and behavior describe grooming, dress, psychomotor activity, and attitude. Speech captures rate, volume, and fluency. Mood is the client's stated emotional state, while affect is your observation of its range, intensity, and congruence. Thought process describes the form and flow of thinking (linear, tangential, disorganized), while thought content covers what the client is thinking about, including any delusions, obsessions, or suicidal or homicidal ideation. Perception covers hallucinations and other disturbances.

Cognition is assessed through orientation, attention, memory, and, where indicated, abstraction and fund of knowledge. Insight is the client's awareness of their own condition, and judgment is their capacity to make sound decisions. Together these domains give a precise, shareable snapshot. Good MSE documentation uses specific descriptive language: 'affect constricted and incongruent with stated euthymic mood' tells another clinician far more than 'affect normal.'

The MSE is a description, not a diagnosis, and it reflects only the moment of the exam. Record findings even when they are unremarkable, since a documented normal exam is clinically meaningful. Repeat the MSE over time to track change, and always document any safety-relevant findings, such as suicidal ideation or command hallucinations, and the action taken.

One way to hold all the domains in mind during an interview is the mnemonic ASEPTIC: Appearance, Speech, Emotion (mood and affect), Perception, Thought, Insight and judgment, and Cognition. It is a memory aid, not a scoring system, and the order you actually work through the domains does not need to match it. The MSE is also distinct from brief cognitive screens like the Mini-Mental State Exam or the Montreal Cognitive Assessment, which score only the cognition domain in more depth and are typically used alongside the full MSE rather than in place of it.

The most common documentation mistakes are using conclusory labels instead of specific behavioral description, conflating mood with affect, and skipping a domain because nothing stood out rather than recording that it was unremarkable. This template is built for clinicians, supervisees, and students across settings, from an intake session to an inpatient unit, and it complements rather than replaces a full Intake / Biopsychosocial Assessment Template or a Suicide Risk Assessment Tool when safety concerns are present.
