This poses a challenge for people who live in areas with inadequate primary care services and those who have economic, insurance, or other transient hardships (transportation, time, etc.) that limit their access to healthcare services. Digital cognitive assessments (DCAs) with remote testing capabilities have emerged as an efficient and cost-effective solution. The aim of this study was to validate the reliability of BrainCheck, a platform for DCAs, when self-administered remotely.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 46 participants (60.9% female; age range 52\u201376) remotely completed a battery of six BrainCheck cognitive assessments twice on the same device (iPad\u2009=\u20098, iPhone\u2009=\u20095, laptop\u2009=\u200933): the participants self-administered in one session and were administered by a research coordinator (RC) in the other session. Thirty participants completed the self-administered session first, while 16 completed it second. The inter-session interval (ISI) varied across participants, from within the same day to 21 days apart. Testing outcomes, including the duration of time needed to complete the battery, the raw score from each assessment, and the raw overall score, were compared between the two sessions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found moderate or good agreement between self- and RC-administered performance, with intraclass correlation ranging from 0.59 to 0.83. Results from mixed-effects modeling further confirm the non-significant difference between self- vs. RC-administered testing performance, which is independent of other factors including testing order, ISI, device, and participants\u2019 demographic characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These results demonstrate the feasibility of remote self-administration using BrainCheck.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fdgth.2025.1571053","type":"journal-article","created":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T05:27:30Z","timestamp":1751520450000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Reliability of remote self-administered digital cognitive assessments: preliminary validation study"],"prefix":"10.3389","volume":"7","author":[{"given":"Duong","family":"Huynh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siao","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Hosseini Ghomi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary","family":"Patterson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"729","DOI":"10.7326\/M15-0381","article-title":"The burden of health care costs for patients with dementia in the last 5 years of life","volume":"163","author":"Kelley","year":"2015","journal-title":"Ann Intern Med"},{"key":"B2","doi-asserted-by":"publisher","first-page":"459","DOI":"10.1016\/j.jalz.2016.03.001","article-title":"2016 Alzheimer\u2019s disease facts and figures","volume":"12","year":"2016","journal-title":"Alzheimers Dement"},{"key":"B3","doi-asserted-by":"publisher","first-page":"2717","DOI":"10.3390\/ijerph18052717","article-title":"The economic burden of dementia: evidence from a survey of households of people with dementia and their caregivers","volume":"18","author":"Oba","year":"2021","journal-title":"Int J Environ Res Public Health"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1326","DOI":"10.1056\/NEJMsa1204629","article-title":"Monetary costs of dementia in the United States","volume":"368","author":"Hurd","year":"2013","journal-title":"N Engl J Med"},{"key":"B5","article-title":"World Alzheimer Report 2011: The benefits of early diagnosis and intervention","author":"Prince","year":""},{"key":"B6","article-title":"Shortage areas","year":""},{"key":"B7","article-title":"Primary Care Health Professional Shortage Areas (HPSAs).
