The Short Portable Mental Status Questionnaire (SPMSQ) is a 10-item oral cognitive screen developed by Eric Pfeiffer in 1975. It assesses orientation to time and place, personal information recall, and serial calculation. Scoring is based on number of errors (0–10), with higher error counts indicating greater cognitive impairment.

How is the SPMSQ interpreted?

SPMSQ error bands: 0–2 errors = intact cognitive function; 3–4 errors = mild cognitive impairment; 5–7 errors = moderate cognitive impairment; 8–10 errors = severe cognitive impairment. These bands are applied after education adjustment (allow 1 additional error for less than grade school; subtract 1 error for post-high school education).

What is the education adjustment for SPMSQ?

Pfeiffer's original scoring includes an education adjustment: allow 1 additional error if the patient did not complete grade school education; subtract 1 allowable error if the patient has post-high school education. This adjustment reduces misclassification due to educational rather than pathological cognitive differences.

What are the 10 SPMSQ questions?

The 10 questions cover: (1) today's date, (2) day of week, (3) name of this place, (4) phone number or address, (5) age, (6) date of birth, (7) current president, (8) former president, (9) mother's maiden name, (10) count backward from 20 by threes. Each incorrect answer counts as one error.

How does SPMSQ compare to MMSE and MoCA?

SPMSQ is faster (3–5 minutes, no paper or pencil needed) but less sensitive for mild cognitive impairment than the MMSE (30 items, 10–15 minutes) or MoCA (30 items, 10–15 minutes). MMSE and MoCA assess additional cognitive domains not captured by SPMSQ. SPMSQ is best for rapid triage; MMSE or MoCA should be used when detailed cognitive profiling is needed.

Can SPMSQ diagnose dementia?

No. SPMSQ is a screening tool, not a diagnostic instrument. A positive screen (3+ adjusted errors) supports further evaluation but cannot confirm a dementia diagnosis. Dementia diagnosis requires comprehensive cognitive testing, functional assessment, history from collateral informants, medical workup, and in some cases neuroimaging.

How long does SPMSQ take to administer?

The SPMSQ typically takes 3 to 5 minutes to administer. No paper, pencils, or props are required. It can be administered by physicians, nurses, or trained allied health workers in any clinical setting, making it one of the most time-efficient structured cognitive screens available.

What clinical actions should follow a positive SPMSQ?

A positive SPMSQ (3+ adjusted errors) should prompt: laboratory workup for reversible causes (TSH, B12, folate, CBC, metabolic panel); more detailed cognitive screening with MoCA or SLUMS; assessment for delirium and depression; functional status evaluation; collateral history from caregivers; and referral to geriatrics or a memory clinic if impairment is confirmed.

Can SPMSQ be used for serial monitoring of cognitive decline?

Yes. Tracking SPMSQ error counts over months to years provides a simple longitudinal cognitive trajectory. A change of 2 or more errors between assessments is generally considered clinically meaningful and warrants re-evaluation.

What are the main limitations of SPMSQ?

Key limitations include: low sensitivity for mild cognitive impairment; susceptibility to education, language, and cultural biases; president items are culturally specific to US political figures; SPMSQ does not assess executive function, visuospatial ability, or language; and performance may be transiently affected by acute illness, pain, fatigue, or anxiety.

SPMSQ

The Short Portable Mental Status Questionnaire (SPMSQ), also known as Pfeiffer's questionnaire, is a brief cognitive screen based on number of errors across orientation and calculation-type items. It is commonly interpreted with education-adjusted error thresholds.

Formula: SPMSQ is interpreted by total error count (0-10), with optional education-based adjustment.

How It Works

Administer the 10-Question Oral Interview

The SPMSQ consists of 10 orally administered questions covering orientation and recall: (1) What is today's date — month, day, year? (2) What day of the week is it? (3) What is the name of this place? (4) What is your telephone number or street address? (5) How old are you? (6) When were you born — month, day, year? (7) Who is the current president? (8) Who was the president before? (9) What was your mother's maiden name? (10) Subtract 3 from 20 and keep subtracting 3 from each new number. No writing or paper is required. The entire test typically takes 3 to 5 minutes. Each incorrect answer is counted as one error.

Apply Education-Based Adjustment to the Error Count

After scoring, apply Pfeiffer's education adjustment before interpreting the result. Allow one additional error for patients who did not complete grade school education. Subtract one error for patients with post-high school education (college or beyond). This adjustment reflects the well-established relationship between educational attainment and performance on orientation and recall tasks. Document the education level used for adjustment so that future assessors can reproduce the interpretation and track cognitive changes accurately.

Classify Cognitive Status From Four Error Bands

After education adjustment, apply the four Pfeiffer error bands: 0–2 errors = intact cognitive function (normal screen); 3–4 errors = mild cognitive impairment — indicates need for further evaluation; 5–7 errors = moderate cognitive impairment — strongly supports referral for comprehensive cognitive and functional assessment; 8–10 errors = severe cognitive impairment — requires urgent further evaluation and care planning. A positive screen (3+ errors adjusted) should trigger formal cognitive evaluation, delirium assessment, functional assessment, laboratory workup (thyroid, B12, metabolic panel), and neuroimaging if indicated.

Who Uses the SPMSQ

Rapid Cognitive Triage in Primary Care

Family physicians, internists, nurse practitioners

The SPMSQ is one of the fastest structured cognitive screens available, requiring no paper, no props, and typically under 5 minutes to administer. In primary care, it serves as a first-line cognitive triage tool for patients presenting with memory complaints, caregiver concerns, or functional decline. The error-count format is immediately interpretable without scoring tables. For patients who score 3+ errors, the SPMSQ provides objective documentation of cognitive concern to support referral for comprehensive neuropsychological testing, geriatric consultation, or dementia workup.

Annual Cognitive Surveillance in Older Adults

Geriatric primary care, memory clinic nurses, community health workers

The SPMSQ is well-suited to annual or periodic cognitive surveillance in older adults because it is brief, does not require equipment, and produces a quantitative error count that facilitates longitudinal tracking. A patient who scores 1 error at age 72, 2 errors at age 74, and 4 errors at age 76 shows a clear trajectory of increasing cognitive vulnerability that warrants earlier intervention than if the clinician relied on clinical impression alone. In community health settings, the SPMSQ can be administered by non-physician health workers with minimal training.

Pre-Admission Cognitive Baseline for Hospital and Long-Term Care

Hospitalists, admitting nurses, long-term care teams

Documenting SPMSQ error count at hospital admission or long-term care intake establishes a quantitative cognitive baseline for monitoring post-admission delirium, tracking functional decline, and informing care-planning discussions. When a hospitalized patient's cognitive status deteriorates during admission, the admission SPMSQ score establishes whether the change represents acute-on-chronic impairment or new acute decline — a distinction with major implications for delirium workup, family communication, and discharge planning.

Delirium Screening Support in Medical Wards

Ward nurses, hospitalists, consultation-liaison psychiatry

Although the SPMSQ is primarily a dementia-range cognitive screen rather than a dedicated delirium instrument, significantly elevated error counts in a patient with a previously documented normal SPMSQ can signal acute cognitive deterioration consistent with delirium. Paired with dedicated delirium tools such as the [4AT](/tools/4at-delirium) or [CAM](/tools/cam-delirium), the SPMSQ provides complementary information about the patient's cognitive baseline before the current hospitalization.

Cognitive Impairment Documentation for Capacity Assessment

Physicians, social workers, legal and ethics consultants

The SPMSQ provides a brief, standardized, and documented cognitive measurement that can support — but does not replace — formal capacity assessments. In situations where clinical decisions require documentation of cognitive status (surgery consent, discharge planning, financial decision-making concerns), an SPMSQ error count provides a standardized, reproducible data point. Scores in the moderate-to-severe range (5–10 errors) raise concerns about decision-making capacity and should trigger formal capacity assessment and, if indicated, ethics or legal consultation.

Pro Tips

Ask for Phone Number, Not Address, When Possible

Question 4 asks for either a phone number or a street address. Phone numbers are generally easier for older adults to recall accurately and are less subject to recent environmental change — patients who have recently moved may not yet know their new address. Asking for the phone number first reduces erroneous scoring of genuine memory impairment versus recency of relocation.

Administer in a Quiet, Distraction-Free Environment

SPMSQ performance can be confounded by environmental noise, interruptions, pain, and anxiety. Administer the questionnaire in a calm, distraction-free setting and allow the patient adequate time to respond. Rushing the patient or administering SPMSQ in a chaotic environment may inflate error counts reflecting situational stress rather than intrinsic cognitive impairment.

Serial Subtraction Errors Require Careful Scoring

The serial subtraction item (subtract 3 from 20 repeatedly) has nuanced scoring: if the patient makes one error but then continues correctly from the wrong number, count only 1 error. Do not count multiple errors for a single cascade of incorrect numbers flowing from one initial mistake — count only the number of discrete individual subtraction errors. This distinction can shift the total error count by 1–2 points and change the impairment classification.

Document the Education Level Used for the Adjustment

When applying the education adjustment, document in the medical record not only the raw SPMSQ error count but also the education level and the adjusted interpretation band used. This ensures that providers reviewing the chart at a later date can reproduce the interpretation and track cognitive changes accurately against the same adjusted baseline.

A Perfect Score Does Not Rule Out Mild Cognitive Impairment

The SPMSQ is designed as a cognitive screen for moderate-to-severe impairment, not a sensitive MCI detector. A patient with 0 SPMSQ errors may still have mild cognitive impairment that affects complex functional tasks. If clinical concern for MCI persists despite a normal SPMSQ, supplement with [MoCA](/tools/moca-score) or formal neuropsychological testing, which assess additional domains including visuospatial function and executive function.

Use With CAM or 4AT When Delirium Is Suspected

When a patient presents with acute confusion, the SPMSQ alone is insufficient — it does not assess the fluctuating attention and acute onset features that define delirium. Pair SPMSQ with the [4AT](/tools/4at-delirium) or [CAM](/tools/cam-delirium) to differentiate delirium from chronic cognitive impairment. A previously normal SPMSQ suddenly showing 5+ errors strongly supports acute-onset cognitive change consistent with delirium.

Consider Hearing and Vision Impairment Before Scoring

Hearing impairment in older adults can cause question misunderstanding that mimics cognitive failure. Before administering, ensure the patient can hear the questions clearly — speak slowly, face the patient, and use hearing aids if available. Document any accommodations made in the medical record.

Pair With Collateral History When Score and Family Report Conflict

When SPMSQ results conflict with family observations, administer a collateral-history instrument like the [AD8 Dementia Screen](/tools/ad8-dementia-screen) directly to the family member to clarify whether day-to-day functioning has changed. Family observations in familiar home environments may miss impairment that SPMSQ's standardized probing reveals.

Common Questions About Your Results

A score of 3–4 errors (mild cognitive impairment band, adjusted for education) warrants a structured follow-up approach. First, assess whether this represents a change from prior cognitive status. Perform baseline laboratory work (CBC, metabolic panel, TSH, B12, folate) to rule out reversible causes. Administer a more sensitive cognitive screen such as [MoCA](/tools/moca-score) or [SLUMS](/tools/slums-score). Assess for delirium and depression, which can mimic cognitive impairment on SPMSQ recall items. Schedule a follow-up visit in 3–6 months with repeat SPMSQ.

Families may observe the patient in familiar, supportive home environments where compensatory strategies mask true impairment. Conversely, the testing environment may have introduced anxiety or fatigue that transiently elevated the error count. Administer a collateral-history instrument like the [AD8 Dementia Screen](/tools/ad8-dementia-screen) directly to the family member, and consider formal neuropsychological evaluation if the discrepancy persists on serial testing.

Refusal to answer a SPMSQ question is typically scored as an error in formal administration because the test requires an accurate response. Document the refusal rather than the error type in the medical record to preserve clinical context. If cultural or political factors are likely to affect multiple items, consider a supplementary cognitive screen with more neutral content alongside the formal SPMSQ.

Questions 7 and 8 assume familiarity with local political leadership. Recent immigrants may score 1–2 errors on these items purely due to unfamiliarity rather than cognitive impairment. Document the cultural context and supplement with a culturally adjusted alternative such as [MMSE](/tools/mmse-score) or [MoCA](/tools/moca-score), which have been adapted and validated in multilingual populations.
