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.

f1-ppa-9-857: Schematic presentation of the iterative phases.

Mentions: We used an iterative approach consisting of four phases (Figure 1) to determine users’ motivation to use iVitality (phases 1 and 2), formulate requirements to optimize iVitality (phases 2 and 3), and test the usability of the smartphone application as part of the online platform (phase 4). This approach was chosen because multiple iterative phases continuously elicit, test, and evaluate users’ expectations and preferences.9 In this way, triangulation will take place; multiple methods are used to collect and interpret data to ensure an accurate representation of these data. The goals and rationale for applying qualitative methods during the various phases are described in more detail below. In this study, a first prototype of the smartphone application was used in which blood pressure could be monitored using a wireless blood pressure monitoring device that forward measurements to the smartphone application via Bluetooth. Besides blood pressure monitoring, the smartphone application contained the following functionalities: graphical feedback about blood pressure values, cognition tests (measuring reaction time), physical activity monitoring (using a sensor built-in the smartphone), and lifestyle monitoring (by providing short questions about lifestyle patterns). The study took place between October 2012 and April 2013.
