Montreal Cognitive Assessment Citation: How to Properly Reference the MoCA in Research and Clinical Practice

The montreal cognitive assessment citation is one of the most frequently searched topics among researchers, clinicians, and students who use the MoCA in academic work. Properly crediting Ziad Nasreddine and colleagues for developing this widely-used screening tool is not just a matter of academic integrity — it ensures that readers can trace the original validation study, understand the tool's psychometric foundations, and appreciate the clinical context in which it was designed. Whether you are writing a journal article, completing a clinical report, or submitting a thesis, getting the citation exactly right matters more than you might think.

The MoCA was first published in 2005 in the Journal of the American Geriatrics Society, and that original paper remains the primary reference for the instrument to this day. The citation is distinctive because the tool has evolved significantly since its introduction — with updated scoring criteria, alternative versions, and a growing library of normative data — yet most style guides and journals still expect a reference to the founding validation study.

Understanding which version of the MoCA you administered, which year's norms you applied, and whether you used a supplementary adaptation all affects how your reference list should be constructed. A thorough cognitive functions test citation supports the reproducibility of your research.

Many clinicians confuse the MoCA with the Mini Mental Status Exam, often called the MMSE or mini mental status exam in shorthand. While both instruments screen for cognitive impairment, they differ substantially in sensitivity, item composition, and the populations for which they are validated. The MoCA was specifically designed to detect mild cognitive impairment that the MMSE routinely misses, and this distinction is important when you are deciding which citation to include in your methods section. Referencing the wrong instrument, or conflating the two in your prose, can undermine the credibility of an otherwise rigorous study.

Citation formats vary depending on the style guide your publication or institution requires. APA, AMA, Vancouver, and Chicago styles each handle author names, journal abbreviations, volume numbers, and page ranges slightly differently. For a tool as widely cited as the MoCA, minor formatting errors are immediately visible to peer reviewers who have seen the reference dozens of times. This article walks you through every major citation style with annotated examples, explains how to handle adapted or translated versions, and addresses the most common mistakes researchers make when referencing this instrument in their work.

Beyond the core citation, you may also need to reference the MoCA's official website, its training and certification resources, or the specific normative tables published by Nasreddine and collaborators over the years. Each of these sources has its own preferred format, and some publishers have begun requiring digital object identifiers (DOIs) for all electronic resources, which adds another layer of complexity. Knowing where to locate verified DOIs and how to integrate them into different citation formats will save you significant time during manuscript preparation and reduce the likelihood of citation-related revisions from peer reviewers.

This guide is designed for US-based audiences including neuropsychologists, geriatricians, occupational therapists, speech-language pathologists, and graduate students who encounter the MoCA regularly in clinical or research settings. The information here applies to standard cognitive screening contexts, not to specialized pediatric assessments — the mini mental health status examination used in pediatric populations follows different referencing conventions covered elsewhere on this site. By the end of this article, you will have a complete toolkit for citing the MoCA accurately, efficiently, and in compliance with the most commonly requested style guides.

It is also worth noting that citation practices around the MoCA have attracted renewed attention in recent years as debates about cognitive screening in public figures — including discussions about trump cognitive decline assessments — have brought the instrument into mainstream media coverage. When citing the MoCA in clinical documentation or public-facing materials, clinicians must balance scientific precision with accessible language, and understanding the original source helps anchor both goals.

Understanding how to format the MoCA citation across different style guides is essential for any researcher who publishes across multiple journals or submits work to institutions with varying requirements. The three most commonly required styles in US clinical and research settings are APA (American Psychological Association), AMA (American Medical Association), and Vancouver. Each handles the same source material differently, and confusing their conventions is a leading cause of citation corrections during peer review. Let us walk through each format with a complete, annotated example you can copy directly into your reference manager.

In APA 7th Edition, the MoCA citation reads: Nasreddine, Z. S., Phillips, N. A., Bédirian, V., Charbonneau, S., Whitehead, V., Collin, I., Cummings, J. L., & Chertkow, H. (2005). The Montreal Cognitive Assessment, MoCA: A brief screening tool for mild cognitive impairment. Journal of the American Geriatrics Society, 53(4), 695–699. https://doi.org/10.1111/j.1532-5415.2005.53221.x. Note that APA 7 includes all authors up to 20 before using an ellipsis, so the full author list should be spelled out here. The journal name is italicized, as is the volume number, but the issue number in parentheses is not.

In AMA style — the standard for most medical journals in the United States — the same source appears as: Nasreddine ZS, Phillips NA, Bédirian V, et al. The Montreal Cognitive Assessment, MoCA: a brief screening tool for mild cognitive impairment. J Am Geriatr Soc. 2005;53(4):695-699. doi:10.1111/j.1532-5415.2005.53221.x. Key differences from APA include the use of abbreviated journal names, the absence of the Oxford comma, and the placement of the year immediately after the author list rather than at the end. The title uses sentence case rather than title case in AMA style.

The Vancouver style, widely used in biomedical journals outside the United States but also required by some US journals including JAMA-affiliated publications, formats the citation as: Nasreddine ZS, Phillips NA, Bédirian V, Charbonneau S, Whitehead V, Collin I, et al. The Montreal Cognitive Assessment, MoCA: a brief screening tool for mild cognitive impairment. J Am Geriatr Soc. 2005 Apr;53(4):695-9. In Vancouver, citations are numbered in order of appearance in the text and listed numerically rather than alphabetically, which completely changes how you manage in-text references compared to APA or AMA.

Reference manager software such as Zotero, Mendeley, and EndNote all carry the MoCA citation in their databases, but the auto-populated entries frequently contain errors — most commonly a misspelled author name, missing co-authors, or an incorrect DOI. Before relying on any auto-imported citation, manually verify each field against the original published article. The DOI 10.1111/j.1532-5415.2005.53221.x is the most reliable lookup key and should resolve correctly via doi.org. If you are using Google Scholar's citation export feature, be aware that it often formats author initials inconsistently across style guides.

When citing the MoCA's official website for protocols, scoring sheets, or training materials, the reference format differs from a journal article citation. For APA 7, a web page citation looks like: MoCA Cognition. (2023). Montreal Cognitive Assessment (MoCA). https://www.mocacognition.com. Accessed [date]. Because the website is maintained by the MoCA organization rather than a single author, treat it as a group author entry.

For AMA and Vancouver styles, the format shifts slightly to place the organization name in the author position and abbreviate the access statement differently. Always double-check current institutional guidance, as some journals have begun treating websites as grey literature and requiring additional justification for their inclusion in reference lists.

Researchers conducting systematic reviews or meta-analyses involving the MoCA often need to cite dozens of individual validation studies alongside the original Nasreddine paper. In these contexts, using a reference manager that supports style-switching is critical — manually reformatting 40 citations from APA to Vancouver is both time-consuming and error-prone. Building a shared Zotero library for your research team, tagged with the specific MoCA version each study used, dramatically reduces formatting errors and makes the montreal cognitive assessment citation process replicable across future projects. Proper citation hygiene from the start of a project saves significant revision time before submission.

Chicago style, used primarily in humanities and social science publications, is rarely required for MoCA-focused research but does appear in interdisciplinary public health and policy work. In Chicago author-date format, the citation reads: Nasreddine, Ziad S., Natalie A. Phillips, Valérie Bédirian, Simon Charbonneau, Victor Whitehead, Isabelle Collin, Jeffrey L. Cummings, and Howard Chertkow. 2005. "The Montreal Cognitive Assessment, MoCA: A Brief Screening Tool for Mild Cognitive Impairment." Journal of the American Geriatrics Society 53 (4): 695–699.

Note that Chicago spells out all author first names in full, which is the most labour-intensive format to produce manually and the one most likely to contain errors when auto-imported from databases.

Adapted and translated versions of the MoCA present some of the most complex citation challenges researchers encounter. As of 2024, the MoCA has been officially translated and validated in more than 90 languages and cultural contexts, from Mandarin and Arabic to Brazilian Portuguese and Swahili.

Each of these adaptations involved a distinct research team, a separate validation study, and an independent publication — all of which require their own citation if you administered that specific version. Simply citing the original English-language Nasreddine paper is insufficient when your participants completed a Hindi or Spanish MoCA, and peer reviewers with expertise in cross-cultural assessment will expect the adaptation study to appear in your reference list.

Finding the correct citation for a specific MoCA adaptation requires navigating both the official MoCA organization's published list of validated translations and independent literature searches in PubMed or PsycINFO. The MoCA organization's website lists official adaptations with links to their validation publications, but not all entries include complete citation details — you may need to trace the original journal article yourself. For commonly used adaptations like the Spanish MoCA or the Chinese MoCA (MoCA-CC), multiple competing validation studies exist, and you should cite the one that most closely matches the normative population your study enrolled.

The MoCA-Basic is a variant specifically designed for individuals with limited formal education or low literacy, developed by Nasreddine and colleagues and published separately from the original instrument. If you administered the MoCA-Basic rather than the standard version, your citation must reference the MoCA-Basic validation study, not just the 2005 original.

Similarly, the telephone-administered MoCA (T-MoCA) — which gained significant traction during the COVID-19 pandemic as in-person assessments became impractical — has its own validation literature that must be cited when this administration format was used. Conflating administration format citations is among the top five citation errors flagged by peer reviewers in clinical neuropsychology journals.

In systematic reviews and meta-analyses, citation requirements for MoCA-related research become even more complex. Researchers must not only cite each included study correctly but also describe the version of the MoCA used in each included study in their data extraction tables.

When pooling sensitivity and specificity data across studies, differences in MoCA version, cutoff score, and normative reference must be clearly documented — and the citations for each normative source must appear in the reference list even if those normative papers are not directly quoted in the text. This level of citation granularity is standard in high-quality systematic reviews and is increasingly required by journals indexed in the Cochrane Database and PROSPERO registry.

Researchers working in telemedicine and digital health are encountering a new category of MoCA citations related to remote and app-based administration. Several technology companies have developed MoCA-licensed digital versions, and the licensing agreements themselves sometimes specify required citation language that goes beyond standard academic referencing norms.

If you are publishing findings from a digitally administered MoCA, check the licensing terms of the specific platform you used — some require acknowledgment of the platform developer in addition to the standard academic citation for the instrument itself. Failing to include required acknowledgments can raise intellectual property issues that extend well beyond peer review.

Normative data for specific age groups and clinical populations represent another layer of citation complexity. Researchers who applied normative adjustments for adults aged 85 and older, for example, may need to cite population-specific normative studies published by groups in Canada, Europe, or the United States that are distinct from the original Nasreddine validation cohort.

The growing field of normative data collection for the MoCA means that the citation landscape continues to expand year over year, and a literature search conducted in 2020 may be outdated by the time a manuscript reaches publication in 2024 or 2025. Building a habit of running updated searches immediately before manuscript submission reduces this risk substantially.

Graduate students and early-career researchers often ask whether they need to cite the MoCA when it appears only as a screening tool to establish eligibility rather than as a primary outcome measure. The answer is yes — whenever you administered the MoCA for any purpose in a published study, you must cite it.

This applies even when the MoCA score was used solely to confirm normal cognition in control participants or to establish minimum cognitive capacity for informed consent. The citation requirement follows the instrument, not the centrality of the instrument to the study's primary aims. Reviewers and readers need to be able to verify the tool's psychometric properties regardless of how prominently it features in your analysis.

Common citation mistakes with the MoCA fall into several predictable categories, and understanding them in advance allows researchers to audit their reference lists systematically before submission. The single most frequent error is an incomplete author list — many researchers list only Nasreddine as the author and add et al., even in styles like APA 7 that require all authors up to 20 to be listed in full.

The original MoCA paper has seven authors, all of whom must appear in APA-style reference lists: Nasreddine, Phillips, Bédirian, Charbonneau, Whitehead, Collin, Cummings, and Chertkow. Dropping any of these names is both inaccurate and a courteous breach toward co-investigators who contributed to the instrument's development.

A second common error involves the journal name abbreviation. In AMA and Vancouver styles, the Journal of the American Geriatrics Society is abbreviated as J Am Geriatr Soc — not JAGS, not J. Amer. Ger. Soc., and not Journal Amer Geriatrics Soc. Using non-standard abbreviations can prevent automated citation matching in bibliometric databases and may trigger style corrections from copy editors at the target journal. Most reference managers default to full journal names rather than abbreviations, so researchers using AMA or Vancouver styles must typically edit auto-imported citations manually to apply the correct abbreviation.

Incorrect page number ranges represent a third common mistake. The original MoCA article spans pages 695 through 699 in volume 53, issue 4 of the Journal of the American Geriatrics Society. Some citation databases list the page range as 695-700 due to an off-by-one counting error in how electronic pages are indexed. Always verify the closing page number — it is 699, not 700.

This type of error is invisible to readers but flags immediately in systematic literature searches that rely on precise bibliographic data for deduplication and retrieval. For researchers concerned about the accuracy of cognitive screening references — including those investigating issues like trump cognitive decline assessments in public discourse — precision in citation details matters at every level.

Missing the DOI is a fourth frequent oversight. While the MoCA's 2005 publication predates widespread DOI adoption, the article was assigned the DOI 10.1111/j.1532-5415.2005.53221.x retroactively, and this identifier is now expected in most modern citation styles including APA 7, AMA, and Vancouver. Some older style guide templates in reference managers still generate MoCA citations without the DOI because the entry was originally catalogued before DOI inclusion became standard. Manually adding the DOI to any auto-generated citation is a simple step that brings the reference into compliance with current expectations across virtually all major biomedical journals.

A fifth class of error involves year confusion. Some researchers cite the MoCA using years other than 2005 — most commonly 2004 (the year the paper was accepted or first published online) or 2010 (when the MoCA website was relaunched). The correct publication year for the original validation paper is 2005, and this is the year that should appear in your reference list and in-text citations regardless of when you personally accessed the article.

Online-first publication dates and DOI registration dates are not the same as the journal publication date and should not be used in formal citations unless your style guide specifically instructs you to provide an Epub ahead of print date.

Researchers who use the MoCA in longitudinal studies face an additional citation complexity: if the instrument's normative standards changed between data collection waves, should you cite the normative paper applicable to the first wave or the most current norms? Standard practice is to cite the normative reference that was used to score and interpret the data, and to disclose in your methods section when different normative standards were applied across waves.

This level of methodological transparency is increasingly expected by high-impact journals in aging research and neuropsychology, and your citation list should reflect each set of norms separately. Consistent citation practice supports the reproducibility of your findings across research groups working with similar populations.

Finally, clinicians who document MoCA results in electronic health records and clinical notes often ask whether formal citations are required in that context. While EHR documentation does not follow academic citation standards, it is considered best practice to note the instrument name, version, date of administration, and total score clearly.

Some institutions have developed standardized MoCA documentation templates that include a brief reference to the Nasreddine et al. source — this practice is particularly valuable in medicolegal contexts where the psychometric properties of the screening tool may need to be established for a court or insurance proceeding. Familiarity with formal citation requirements deepens your understanding of the tool's evidentiary foundations even when full citations are not technically required in the clinical document itself.

Practical tips for managing MoCA citations efficiently begin with setting up your reference manager correctly before you start writing rather than retroactively adding citations during revision. Creating a dedicated MoCA folder or tag in Zotero or Mendeley that contains the verified original citation, the 2019 normative paper, and any adaptation studies relevant to your research allows you to insert citations with a single click and dramatically reduces the risk of version-related errors.

Many research teams conducting ongoing cognitive assessment work maintain a shared group library in Zotero that is curated and verified centrally, so individual lab members do not each need to maintain their own citation files — a practice that also prevents divergent citation formats across a multi-paper research program.

When preparing a manuscript that uses the MoCA, run a final citation audit as a distinct step in your pre-submission checklist, separate from proofreading and statistical verification. This audit should involve pulling up the original PubMed entry for Nasreddine et al. 2005 (PMID 15817019) and comparing each field — authors, title, journal, volume, issue, pages, year, and DOI — against what appears in your reference list.

If you used any MoCA variants or adaptations, open the specific validation paper for each and perform the same field-by-field comparison. This process takes less than ten minutes for most papers and reliably catches the formatting and completeness errors described throughout this article.

For researchers who publish frequently in journals with different style requirements, creating style-specific citation templates for the MoCA in your reference manager saves considerable time over the course of a research career. Rather than reformatting from scratch each time, you can maintain APA, AMA, Vancouver, and Chicago versions of the MoCA citation as separate records in your library, clearly labeled by style.

Some reference managers allow you to store style-specific notes within a single record, which is an alternative approach. The initial time investment in building these templates pays off exponentially over a career that may involve hundreds of papers referencing this widely used instrument.

Graduate students writing theses and dissertations face a particular challenge because institutional formatting requirements sometimes differ from standard journal style guides. Some US universities require all dissertations to follow APA 7, while others allow students to follow the style of their target journal — meaning a psychology PhD student writing a clinically focused dissertation might correctly use AMA style with numbered citations. Always check with your thesis supervisor and institutional graduate school formatting office before committing to a citation style, as retrofitting 200 citations from APA to Vancouver at the dissertation defense stage is an experience best avoided entirely.

Citation management is also increasingly important for researchers preparing grant applications, where preliminary data sections routinely cite the MoCA as a primary or secondary outcome measure. Grant reviewers, particularly those on NIH study sections focused on aging, Alzheimer's disease, or neurological disorders, are deeply familiar with the MoCA literature and will notice citation errors.

In a competitive funding environment where every detail contributes to the overall impression of rigor and attention to scientific detail, a correctly formatted and complete MoCA citation is a small but meaningful signal of methodological competence. Conversely, a sloppy citation in a preliminary data section can inadvertently raise questions about the quality of your record-keeping in the proposed study itself.

Interdisciplinary research teams — combining neuropsychologists, occupational therapists, speech-language pathologists, and biostatisticians — often struggle with citation consistency because team members may work from different style guides in their primary disciplines. Establishing a single agreed-upon citation standard at the beginning of a project, documented in the team's research protocol, prevents the situation where different sections of the same manuscript are formatted in different styles.

Designating one team member as the citation curator — responsible for maintaining the shared reference library and performing the pre-submission citation audit — is a simple organizational strategy that pays substantial dividends in manuscript quality and submission efficiency.

Ultimately, the montreal cognitive assessment citation is both a technical bibliographic task and a gesture of professional respect toward the researchers who invested years in developing, validating, and refining one of clinical neuroscience's most valuable screening tools. Getting it right matters not just for peer review compliance but for the integrity of the scientific record.

As cognitive screening tools like the MoCA become increasingly central to clinical care, policy decisions, and public discourse, the accuracy and completeness of the literature that supports them takes on heightened importance. Treating citation accuracy as a non-negotiable standard in your own work contributes to a cumulative scientific record that other researchers, clinicians, and ultimately patients can genuinely rely upon.
