“…However, the remote, self-paced nature of smartphone-based research can make it more representative in other respects, compared to in-person lab-based studies. 78 Therefore, convergence across a variety of research methods is key. Fourth, we cannot exclude the possibility that domain differences contributed to the differences between subjective and objective assessment.…”

INTRODUCTION: Early detection of both objective and subjective cognitive impairment is important. Subjective complaints in healthy individuals can precede objective deficits. However, the differential associations of objective and subjective cognition with modifiable dementia risk factors are unclear.METHODS: We gathered a large cross-sectional sample (N=3,376, age 18–86) via smartphone app and quantified the associations of 13 risk factors with subjective memory problems and three objective measures of executive function (visual working memory, cognitive flexibility, model-based planning).RESULTS: Depression, socioeconomic status, hearing handicap, loneliness, education, smoking, tinnitus, less exercise, smaller social network, stroke, diabetes, and hypertension were all associated with impairments in at least one cognitive measure. Subjective memory had the strongest link to most factors; these associations persisted after controlling for depression. Age mostly did not moderate these associations.DISCUSSION: Subjective cognition was more sensitive to self-report risk factors than objective cognition. Smartphones could facilitate detecting earliest cognitive impairments.

“…Under sub-theme 2 (low-cost and efficient solutions), Watermeyer & Calia [16], Parra et al [14], Muniz-Terrera et al [17], and Danso et al [18] offer exciting insights into how new advances in neuropsychology, mobile technology, and data sciences (eg, speech and text analysis) can overcome language, educational, and cultural biases as well as problems with repeated measures embedded within established cognitive measures. These emerging tests and technologies also improve precision and sensitivity in the detection of pre-symptomatic Alzheimer’s disease.…”

“…These emerging tests and technologies also improve precision and sensitivity in the detection of pre-symptomatic Alzheimer’s disease. These advances offer “a new paradigm for cognitive testing” that opens up possibilities for the creation of harmonised longitudinal data on cognitive ageing across diverse populations globally [17]. As many of these emerging tools and technologies are designed with affordability and ease of administration in mind, they offer important opportunities for disease prevention as well as bridging the gap in knowledge generation between high income countries and their LMIC counterparts.…”

“…Furthermore, these tasks were designed for use on large, touchscreen tablet devices and have not yet been adapted for use on smaller, more mobile devices, such as smartphones, which are used by an increasing number of older people [ 23 ]. Therefore, there is an impetus to adapt such tasks for use on smartphone devices and meet the needs of those living with clinical conditions that affect their cognitive abilities [ 24 ].…”

Background The benefits of involving those with lived experience in the design and development of health technology are well recognized, and the reporting of co-design best practices has increased over the past decade. However, it is important to recognize that the methods and protocols behind patient and public involvement and co-design vary depending on the patient population accessed. This is especially important when considering individuals living with cognitive impairments, such as dementia, who are likely to have needs and experiences unique to their cognitive capabilities. We worked alongside individuals living with dementia and their care partners to co-design a mobile health app. This app aimed to address a gap in our knowledge of how cognition fluctuates over short, microlongitudinal timescales. The app requires users to interact with built-in memory tests multiple times per day, meaning that co-designing a platform that is easy to use, accessible, and appealing is particularly important. Here, we discuss our use of Agile methodology to enable those living with dementia and their care partners to be actively involved in the co-design of a mobile health app. Objective The aim of this study is to explore the benefits of co-design in the development of smartphone apps. Here, we share our co-design methodology and reflections on how this benefited the completed product. Methods Our app was developed using Agile methodology, which allowed for patient and care partner input to be incorporated iteratively throughout the design and development process. Our co-design approach comprised 3 core elements, aligned with the values of patient co-design and adapted to meaningfully involve those living with cognitive impairments: end-user representation at research and software development meetings via a patient proxy; equal decision-making power for all stakeholders based on their expertise; and continuous user consultation, user-testing, and feedback. Results This co-design approach resulted in multiple patient and care partner–led software alterations, which, without consultation, would not have been anticipated by the research team. This included 13 software design alterations, renaming of the product, and removal of a cognitive test deemed to be too challenging for the target demographic. Conclusions We found patient and care partner input to be critical throughout the development process for early identification of design and usability issues and for identifying solutions not previously considered by our research team. As issues addressed in early co-design workshops did not reoccur subsequently, we believe this process made our product more user-friendly and acceptable, and we will formally test this assumption through future pilot-testing.
