What Is a Mental Status Examination?
The mental status examination (MSE) is a structured description of a client's current mental functioning, based on what the clinician observes and asks during the interview. It is the psychiatric equivalent of a physical examination: a systematic snapshot of functioning at one point in time.
This page is the complete guide to the exam itself. It covers the components of an MSE, how to do and document one, a blank template, and two completed sample write-ups: a client with moderate depression and an unremarkable exam. For descriptor vocabulary with definitions and example sentences for every component, see the companion MSE terminology bank.
The MSE combines direct observation with the client's answers to targeted questions about current experience, such as mood, suicidal thoughts and perceptions. It describes the present encounter rather than history; keep reported experiences distinct from observed findings. These findings form a critical component of diagnostic assessment, risk evaluation, treatment planning, and monitoring of clinical change over time.
Every mental health professional — psychologists, psychiatrists, social workers, counselors, and psychiatric nurse practitioners — should be proficient in conducting and documenting a thorough MSE.
When You Need It
- During initial intake or diagnostic evaluation as part of a comprehensive assessment
- When conducting a psychiatric evaluation for medication management
- During crisis assessments or emergency psychiatric evaluations
- When a client's presentation changes significantly from baseline
- For forensic evaluations, competency assessments, or court-ordered evaluations
- When documenting justification for a change in level of care (e.g., inpatient admission)
- At reassessment intervals as required by agency policy or insurance
Mental Status Exam Components at a Glance
Use this table as a checklist. Every component should appear in a complete MSE, even when the finding is unremarkable.
| Component | What you document | How it is usually assessed | Unremarkable example |
|---|---|---|---|
| Appearance | Apparent vs. stated age, grooming, hygiene, dress, build, notable features | Observation from first contact | "Appears stated age; well-groomed, casually dressed." |
| Behavior / psychomotor | Cooperation, eye contact, activity level, abnormal movements | Observation throughout | "Cooperative, good eye contact, no abnormal movements." |
| Speech | Rate, rhythm, volume, articulation, spontaneity | Listening to natural conversation | "Speech normal in rate, rhythm, and volume." |
| Mood | The client's own description of how they feel | Direct question; quote the answer | Mood: "pretty good this week." |
| Affect | Observed emotional expression: quality, range, congruence, reactivity | Observation throughout | "Affect euthymic, full range, congruent with mood." |
| Thought process | Organization and flow of thinking | Inferred from how the client answers | "Linear and goal-directed." |
| Thought content | Preoccupations, delusions, obsessions, suicidal and homicidal ideation | Spontaneous content plus direct questions | "Denies SI and HI on direct inquiry; no delusions elicited." |
| Perception | Hallucinations, illusions, depersonalization, derealization | Direct questions plus observation | "Denies hallucinations; not responding to internal stimuli." |
| Cognition | Alertness, orientation, attention, concentration, memory | Informal screening; formal instrument if indicated | "Alert, oriented to person, place, time, and situation; attention intact." |
| Insight | Understanding of own symptoms and need for treatment | Inferred from the whole interview | "Insight good; describes symptoms and treatment goals." |
| Judgment | Quality of recent decisions and awareness of consequences | Reported and observed decision-making | "Judgment good based on recent decisions." |

What to Document in Each Component
Appearance
Document the client's physical presentation as observable to the clinician. This includes estimated age relative to stated age, body habitus, grooming, hygiene, clothing, distinguishing features, and any notable physical characteristics.
Common descriptors: Well-groomed, disheveled, unkempt, age-appropriate dress, overdressed, underdressed, malodorous, thin, obese, well-nourished, appears stated age, appears older/younger than stated age, visible tattoos/piercings, wearing sunglasses indoors, hospital gown.
Behavior and Psychomotor Activity
Document observable behavior including level of activity, cooperativeness, eye contact, and any abnormal movements.
Common descriptors: Cooperative, guarded, hostile, uncooperative, agitated, restless, psychomotor retardation, psychomotor agitation, fidgeting, pacing, tremor, tics, stereotypies, catatonic features, good eye contact, poor eye contact, avoidant of eye contact, appropriate, calm, hypervigilant, withdrawn, engaged, distractible.
Speech
Document the qualities of the client's speech as observed, distinct from the content of what they say (which falls under thought process and thought content).
Common descriptors: Normal rate/rhythm/volume, pressured, rapid, slow, soft, loud, monotone, dysarthric, slurred, impoverished (poverty of speech), tangential, circumstantial, spontaneous, guarded, hesitant, stuttering, latency of response (delayed before answering), mute, talkative, verbose.
Mood
The client's subjectively reported emotional state — what they say they are feeling. This is typically captured in the client's own words and placed in quotation marks.
Common descriptors: Use client's own words when possible — "depressed," "anxious," "fine," "angry," "hopeless," "numb," "okay I guess," "stressed out." If the client cannot articulate mood, note this: "Client had difficulty identifying current mood."
Affect
The clinician's observation of the client's emotional expression. Affect is described along several dimensions: quality (the predominant emotion displayed), range (the variety of emotional expression), congruence (whether affect matches stated mood and topic of conversation), reactivity (whether affect changes appropriately with content), and intensity.
Common descriptors:
- Quality: Euthymic, sad, tearful, anxious, irritable, euphoric, angry, fearful, suspicious
- Range: Full, restricted, constricted, flat, blunted, labile
- Congruence: Congruent with mood, incongruent (e.g., smiling while discussing a loss), mood-congruent, mood-incongruent
- Reactivity: Reactive, nonreactive (does not change with conversation content)
- Intensity: Normal intensity, heightened, diminished
Thought Process
How the client thinks — the organization, flow, and logic of their thinking as reflected in their speech patterns.
Common descriptors: Linear, logical, goal-directed, coherent, circumstantial (overly detailed but eventually reaches the point), tangential (veers off topic and does not return), loose associations (ideas shift between unrelated topics), flight of ideas (rapid shifting with some connection), thought blocking (abrupt cessation mid-thought), perseverative (returning to the same topic repeatedly), disorganized, concrete, abstract.
Thought Content
What the client is thinking about — the subjects, preoccupations, and beliefs that emerge during the interview. This is one of the most clinically important MSE domains because it includes risk assessment.
Include: Suicidal ideation (active or passive, with or without plan/intent), homicidal ideation, delusions (paranoid, grandiose, somatic, referential, erotomanic), obsessions, compulsions, phobias, preoccupations, overvalued ideas, ideas of reference, thought insertion/withdrawal/broadcasting, feelings of guilt or worthlessness.
Common descriptors: No suicidal or homicidal ideation, passive death wish without plan or intent, active suicidal ideation with plan but no intent, paranoid delusions, grandiose delusions, somatic preoccupation, obsessive thoughts about contamination, ruminations about past failures, ideas of reference.
Perception
Whether the client is experiencing any abnormalities in sensory perception.
Common descriptors: No perceptual disturbances, auditory hallucinations (command, conversational, mumbling), visual hallucinations, tactile hallucinations, olfactory hallucinations, illusions, derealization, depersonalization, hypnagogic hallucinations (at sleep onset — generally benign), hypnopompic hallucinations (upon waking).
Cognition
Assess orientation, attention, concentration, and memory. For a brief MSE, informal assessment through the interview is often sufficient. For cognitive concerns, formal instruments such as the Montreal Cognitive Assessment (MoCA) or Mini-Mental State Examination (MMSE) may be administered.
Many clinicians record orientation in four spheres (person, place, time, situation); others record three. Whichever convention you use, name any sphere that is impaired rather than relying on the count alone. For a fuller cognitive work-up, see the cognitive assessment guide.
Common descriptors: Alert and oriented x4 (person, place, time, situation), oriented x3, attention intact, attention impaired, concentration impaired, immediate recall intact, recent memory intact/impaired, remote memory intact/impaired, fund of knowledge average/above average/below average.
Insight
The degree to which the client understands their own condition and the need for treatment.
Common descriptors: Good (recognizes illness and need for treatment), fair (partially acknowledges symptoms but minimizes or externalizes), poor (denies illness or need for treatment), absent (no recognition of illness).
Judgment
The client's capacity to make sound decisions and understand the consequences of their actions. This is assessed through the client's reported decision-making and their behavior during the interview.
Common descriptors: Good, fair, poor, impaired. Base the rating on the client's recent real-world decisions, behavior observed in the interview, and how they describe the likely consequences of their choices.
Mental Status Exam Example (Completed Sample Write-Up)
The following filled-in example shows a complete narrative MSE for a fictional client presenting with moderate depression. Note how each domain uses specific, observable language rather than conclusory labels.
Mental Status Examination — Client with Moderate Depression
Client: A.K., 42-year-old female | Date: 03/19/2026 Setting: Outpatient psychiatric evaluation | Clinician: [Name], PsyD
Appearance: Client is a 42-year-old female who appears her stated age. She presented in casual clothing (sweatshirt and jeans) that was clean but wrinkled. Hair was pulled back in an unkempt ponytail. Hygiene was adequate. No makeup, which she noted was unusual for her. Body habitus is average. No visible scars, tattoos, or distinguishing marks noted.
Behavior/Psychomotor Activity: Client was cooperative with the examination though notably slow to respond throughout the interview. Psychomotor retardation was observed — movements were slow and deliberate, and she shifted positions infrequently. Eye contact was intermittent, predominantly directed downward. She sat slumped in the chair with arms folded across her midsection. No abnormal movements, tics, or tremors observed. Client became tearful twice during the interview when discussing her divorce and her relationship with her teenage daughter.
Speech: Speech was soft in volume and decreased in spontaneity — client provided brief responses and required frequent prompting for elaboration. Rate was slow. Rhythm was normal. No pressured speech, dysarthria, or latency of response beyond what was consistent with psychomotor slowing. Language was coherent and vocabulary suggested average to above-average intellectual functioning.
Mood: "Empty... like I'm just going through the motions."
Affect: Predominantly sad and constricted. Range was restricted — client displayed sadness and brief tearfulness but did not exhibit full-range emotional expression (no smiling, laughing, or anger observed during the 60-minute interview). Affect was congruent with stated mood and with topics discussed. Reactivity was diminished — affective display changed little even when discussing her daughter's recent school achievement, which she described as something that "should make me happy but doesn't." Intensity was diminished overall.
Thought Process: Linear, logical, and goal-directed throughout the examination. Client's thinking was coherent and organized. She was able to follow the interview structure and respond relevantly to questions. No circumstantiality, tangentiality, loose associations, or flight of ideas. Mild poverty of thought content was noted — responses were sparse and lacked the elaboration typical of conversational speech.
Thought Content: Client endorsed persistent feelings of worthlessness, stating, "I've messed up everything that mattered." Endorsed pervasive guilt about her divorce's impact on her daughter. Reports passive suicidal ideation: "Sometimes I think everyone would be better off without me," but denied any active suicidal ideation, plan, intent, or means. Denied history of suicide attempts. Denied homicidal ideation. Full suicide risk assessment and safety planning are documented in the risk assessment section of this evaluation. No delusions, obsessions, compulsions, or phobias elicited. Preoccupied with themes of personal failure and loss.
Perception: Client denied auditory, visual, tactile, or olfactory hallucinations. Denied derealization and depersonalization. No evidence of perceptual disturbance observed during the interview.
Cognition: Client was alert and oriented to person, place, time, and situation. Attention was mildly impaired — she asked for one question to be repeated and lost her train of thought once during the interview. Concentration appeared mildly impaired, consistent with her self-reported difficulty reading and following conversations. Immediate, recent, and remote memory appeared grossly intact based on informal assessment during the clinical interview. Fund of knowledge was consistent with educational and occupational background.
Insight: Fair. Client recognizes that her mood is "not normal" and that her functioning has declined. She acknowledges the need for treatment, stating, "I know I can't keep going like this." However, she attributes her depression primarily to external circumstances (divorce, conflict with daughter) without recognizing the role of cognitive patterns such as self-blame and catastrophizing. She minimizes the severity of her symptoms: "I'm not that bad — some people have it way worse."
Judgment: Fair. Client is maintaining employment and basic self-care despite significant depressive symptoms, suggesting adequate functional judgment. She voluntarily sought psychiatric evaluation, indicating appropriate help-seeking behavior. However, she has been declining social invitations and isolating for several weeks, and she reports making impulsive online purchases "because nothing else makes me feel anything," suggesting some impairment in judgment under emotional distress.

Normal Mental Status Exam Example (Unremarkable Findings)
An unremarkable exam still documents every component. This fictional example shows a brief, complete MSE for an adult seen for an outpatient intake for work-related stress.
Mental Status Examination — Unremarkable Adult Outpatient Exam
Client: R.T., 29-year-old male | Date: 10/12/2026 Setting: Outpatient intake, in person | Clinician: [Name], LCSW
Appearance: Appears stated age. Well-groomed, dressed in business-casual clothing appropriate to the weather. Average build. No notable physical features.
Behavior/Psychomotor Activity: Cooperative and engaged. Eye contact appropriate. Sat comfortably; no psychomotor agitation or retardation, tremor, or abnormal movements.
Speech: Normal rate, rhythm, and volume. Clearly articulated, spontaneous, and conversational.
Mood: "A little stressed about work, but okay overall."
Affect: Euthymic with mild anxiety when discussing deadlines. Full range, including appropriate humor. Congruent with stated mood and reactive to topic.
Thought Process: Linear, logical, and goal-directed. Answered questions directly.
Thought Content: Content focused on workload and a recent change in manager. On direct inquiry, denied suicidal ideation, plan, or intent, and denied homicidal ideation. No delusions, obsessions, or compulsions elicited.
Perception: Denied auditory and visual hallucinations. No evidence of responding to internal stimuli.
Cognition: Alert. Oriented to person, place, time, and situation. Attention and concentration intact throughout the interview. Recent and remote memory grossly intact on informal assessment. Formal cognitive screening not indicated.
Insight: Good. Links his sleep difficulty to work stress and identified specific goals for treatment.
Judgment: Good. Sought help on his own initiative and has been using leave time appropriately.

Brief MSE for a Progress Note
Routine session notes rarely need the full narrative. A one-paragraph version that touches each component is usually enough, with more detail on anything that has changed:
Try this template in My Clinical WriterDownload Blank MSE Template (.docx)MSE: Appears stated age, adequately groomed. Cooperative, good eye contact, no psychomotor changes. Speech normal rate and volume. Mood "tired but better." Affect mildly constricted, brighter than last session, congruent. Thought process linear. Denies SI/HI on direct inquiry; no delusions. Denies hallucinations. Alert and oriented x4. Insight and judgment fair.
How to Do and Document a Mental Status Exam Step by Step
Step 1: Observe from the moment the client enters. Your MSE begins before the formal interview. Note how the client enters the room — gait, posture, grooming, and demeanor. These initial observations inform the Appearance and Psychomotor Activity sections.
Step 2: Assess mood early in the interview. Ask the client directly: "How would you describe your mood today?" or "How have you been feeling emotionally?" Record their response in their own words. This establishes the subjective baseline against which you compare your objective observations of affect.
Step 3: Observe affect throughout the entire interview. Affect is not assessed at a single moment — it is observed across the full session. Note the range, quality, congruence, reactivity, and intensity of emotional expression. Pay particular attention to affect when discussing emotionally charged topics — does the client's expression match the content?
Step 4: Assess speech passively. You do not need to administer a speech test. Simply listen to the client's natural speech and note rate, rhythm, volume, spontaneity, and any abnormalities. Most speech observations can be documented from the natural flow of conversation.
Step 5: Evaluate thought process through the client's verbal responses. Is the client's thinking organized, logical, and goal-directed? Do they answer questions relevantly? Do they go off on tangents? Do they suddenly stop mid-sentence? Thought process is inferred from how the client communicates.
Step 6: Assess thought content through direct inquiry and observation. Some thought content emerges spontaneously (preoccupations, themes of guilt or worthlessness). Other elements require direct questioning — you must ask about suicidal ideation, homicidal ideation, hallucinations, and delusions. Never assume the absence of these without asking.
Step 7: Screen cognition. At minimum, confirm orientation to person, place, time, and situation. Assess attention and concentration through the interview. If cognitive impairment is suspected, administer a formal screening tool (such as the MoCA or MMSE) and document the instrument name and score. Check the instrument's licensing and training requirements before use.
Step 8: Assess insight and judgment last. By the end of the interview, you have enough data to evaluate insight (does the client understand their condition and need for treatment?) and judgment (is the client making reasonable decisions?). These assessments draw on the totality of the interview, not a single question.
Step 9: Write it up in a consistent order. Document each component in the same sequence every time (the components table above works as a checklist), using specific descriptors from the MSE terminology bank. Note the modality, anything you could not assess, and any change from the previous exam.
Common Mistakes
-
Confusing mood and affect. Mood is what the client reports ("I feel depressed"). Affect is what you observe (constricted, tearful, sad). These may be congruent or incongruent — a client who reports feeling "fine" while presenting with flat affect and tearfulness shows incongruence, which is clinically significant and should be documented as such.
-
Documenting only the presence of abnormalities. A complete MSE documents both normal and abnormal findings. Writing "no hallucinations" and "denies suicidal ideation" is just as important as documenting their presence. An omitted domain looks like it was never assessed.
-
Using vague or subjective language. "Client seemed kind of off" is not a clinical observation. Use precise descriptive terminology: "Affect was blunted with diminished reactivity; psychomotor retardation was observed." Specific language improves communication between providers and strengthens the defensibility of your documentation.
-
Conducting the MSE as a checklist interrogation. The MSE should be woven into the clinical interview, not administered as a series of rapid-fire questions. Most MSE domains can be assessed through skilled observation during a conversational interview. Direct questioning is necessary for thought content (suicidality, homicidality, hallucinations) and cognition (orientation), but other domains should emerge naturally.
-
Failing to note changes from previous MSEs. When you have prior MSE data, documenting change is critical. "Affect was brighter and more reactive compared to the initial evaluation on 02/15/2026, when it was described as flat" provides far more clinical value than documenting the current MSE in isolation.
