Bottom Line: Four participants assessed the usability of the smartphone application (phase 4) using a think aloud procedure and a questionnaire measuring ease and efficiency of use (scale 1-7; higher scores indicated better usability).Despite minor technical errors, iVitality was considered easy and efficient to use (mean score 5.50, standard deviation 1.71).The formulated requirements will be embedded to optimize iVitality.

ABSTRACT

Background: The iVitality online research platform has been developed to gain insight into the relationship between early risk factors (ie, poorly controlled hypertension, physical or mental inactivity) and onset and possibly prevention of dementia. iVitality consists of a website, a smartphone application, and sensors that can monitor these indicators at home. Before iVitality can be implemented, it should fit the needs and preferences of users, ie, offspring of patients with dementia. This study aimed to explore users' motivation to participate in home-based health monitoring research, to formulate requirements based on users' preferences to optimize iVitality, and to test usability of the smartphone application of iVitality.

Methods: We recruited 13 participants (aged 42-64 years, 85% female), who were offspring of patients with dementia. A user-centered methodology consisting of four iterative phases was used. Three semistructured interviews provided insight into motivation and acceptance of using iVitality (phase 1). A focus group with six participants elaborated on expectations and preferences regarding iVitality (phase 2). Findings from phase 1 and 2 were triangulated by two semistructured interviews (phase 3). Four participants assessed the usability of the smartphone application (phase 4) using a think aloud procedure and a questionnaire measuring ease and efficiency of use (scale 1-7; higher scores indicated better usability).

Results: All participants were highly motivated to contribute to dementia research. However, the frequency of home-based health monitoring should not be too high. Participants preferred to receive feedback about their measurements and information regarding the relationship between these measurements and dementia. Despite minor technical errors, iVitality was considered easy and efficient to use (mean score 5.50, standard deviation 1.71).

Conclusion: Offspring of patients with dementia are motivated to contribute to home-based monitoring research by using iVitality and are able to use the smartphone application. The formulated requirements will be embedded to optimize iVitality.

Mentions: The session further elaborated on the mentioned factors regarding self-monitoring and also on how the relationship between high blood pressure and the risk for developing dementia could be explained better. When monitoring blood pressure at home, the current literature and guidelines recommend that blood pressure should be monitored twice per day (morning and evening) by performing two consecutive measurements for 4 days a week. Participants considered it impractical to follow these guidelines for a lengthy period of time (eg, 6 months) due to work or exceptional circumstances such as vacations. In addition, not all participants preferred receiving daily questions about their lifestyle. This would remind them and keep them too preoccupied with the idea of being at risk for dementia. Further, participants preferred some adjustments in the graphical representation of their measured data. A graphical output of the first version of the smartphone application is shown in Figure 2A. Some participants mentioned preferring a reference line in the graph reflecting blood pressure values indicating the accepted range of blood pressure according to their age group. Therefore, during phase 4, the usefulness of a new graphical design was tested, representing the measured blood pressure values along with a reference line as shown in Figure 2B. In addition, participants indicated that they would like to receive information about blood pressure and lifestyle regarding dementia alongside their data. This could increase their awareness of the relationship between health, lifestyle, and dementia.
