Older adults' perceptions of using iPads for improving fruit and vegetable intake: an exploratory study.
Fruit and vegetable (FV) consumption can improve older adults' health outcomes, but conventional interventions can be resource demanding and make it difficult to provide just-in-time intervention content. iPad-based interventions may help overcome these limitations, but little is known about how older adults might perceive and use iPads for FV consumption. To address this gap in the literature, we conducted a qualitative study to explore older adults' perceptions and use of iPads for improving FV consumption between February and August of 2012. Five focus group sessions each lasting 120 min were conducted with 22 older adult participants. During each session, participants received guided exposure and instruction on iPad use and then explored three iPad applications targeting FV consumption (MyFood, FiveADay Lite, and Whole Foods Market Recipes). Detailed notes from focus group interviews were analyzed with a grounded theory approach that applied a constant comparative method to enable themes to emerge from the data. Three themes were identified from the data regarding participants' baseline perceptions of iPads. These included (a) limited knowledge on iPad's functions, (b) iPads were intended for younger users, and (c) iPads were too expensive. Themes identified regarding participants' perceptions of iPads after guided exposure included (a) the touchscreen was easier to use than a computer mouse, (b) tapping the interface required practice, (c) portability was an asset in conjunction with functionality, (d) portability and functionality supported personal interests, (e) the difficulty of learning an iPad's functions varied, and (f) practice and instruction helped overcome fear of the iPad. Finally, participants recommended iPad app features that could help them overcome barriers to their FV intake. These included (a) locating inexpensive FV from nearby sources, (b) providing tailored food and recipe suggestions, and (c) tracking and communicating FV intake with a doctor. These findings have important implications for future research on mobile app-based eHealth interventions to improve older adults' FV intake.
