Prospective and Retrospective Memory Questionnaire
Also known as: PRMQ, Prospective Retrospective Memory Questionnaire
The Prospective and Retrospective Memory Questionnaire (PRMQ) is a 16-item self-report instrument designed to measure subjective memory complaints across two distinct memory domains: prospective memory (remembering to do things in the future) and retrospective memory (remembering past events and information). Developed by Crawford and colleagues at the University of Edinburgh in 2003, the PRMQ provides a brief, validated tool for assessing everyday memory lapses and their impact on functional well-being in both clinical and non-clinical populations.

When to use it
The PRMQ is appropriate for assessing subjective memory complaints in primary care, geriatric clinics, neuropsychology, occupational health, and research contexts. It is useful for understanding patients' functional concerns and the impact of memory on daily activities. The PRMQ can help clinicians decide whether formal neuropsychological testing is warranted and can track subjective memory-related distress over time. However, the PRMQ is not diagnostic for dementia, mild cognitive impairment, or other memory disorders and should be integrated with objective testing and clinical judgment.
Strengths & limitations
- Distinct measurement of prospective and retrospective memory — separates two fundamental memory types, providing more nuanced assessment than instruments measuring only retrospective memory.
- Brief and self-administered — takes 5–10 minutes; no clinician training required; can be completed in clinical settings or remotely.
- Strong psychometric properties — good internal consistency (α ≈ 0.80), test–retest reliability (r ≈ 0.75–0.80), and validity across age groups and clinical populations.
- Captures functional impact — emphasizes everyday memory experience relevant to daily activities (remembering appointments, forgetting conversations).
- Weak correlation with objective memory tests — high PRMQ scores do not necessarily indicate cognitive impairment; the instrument measures subjective complaint burden rather than objective memory ability.
- Vulnerable to mood and situational factors — depression, anxiety, stress, fatigue, and life changes substantially inflate PRMQ scores independent of true memory ability.
- Not diagnostic — the PRMQ does not diagnose dementia or memory disorders; it is a screening or descriptive tool only.
- Limited longitudinal data — fewer published studies examining PRMQ change as a predictor of cognitive decline or dementia conversion compared to instruments like the MMSE.
Frequently asked
What is the difference between prospective and retrospective memory in the PRMQ?
Prospective memory (PRMQ subscale 1) involves remembering to do things in the future (remembering an appointment, taking medication). Retrospective memory (PRMQ subscale 2) involves recalling past information (names, conversations, where you put things). Both are assessed separately on the PRMQ, allowing clinicians to identify which type of memory is more problematic.
If a patient scores high on the PRMQ but has normal objective memory tests, what does that mean?
Discordance between subjective complaints (PRMQ) and objective test performance is common and often reflects mood (depression, anxiety), stress, sleep deprivation, or attentional fatigue rather than true memory impairment. However, some patients with early cognitive decline report high subjective complaints before objective deficits emerge. Assessment of mood and stress is essential; if concern persists, repeat testing in 6–12 months.
Can the PRMQ be used to diagnose mild cognitive impairment or dementia?
No. The PRMQ is a subjective complaint instrument and cannot diagnose cognitive disorders. Diagnosis requires comprehensive cognitive assessment, clinical evaluation, imaging, biomarkers, and functional assessment. However, PRMQ can be a component of a broader cognitive workup.
What PRMQ score should prompt referral for formal neuropsychology?
There is no absolute cutoff. A PRMQ score of 40+ is elevated relative to normative data and may warrant consideration of formal testing, especially if accompanied by functional decline or concern on clinical interview. Always integrate PRMQ with clinical judgment, mood assessment, and functional history.
