Emergence of tablet computers h.s led to interest in th.ir use to impact h.alth.related beh.viors of users. h.wever, little is known regarding wh.ch.devices are most effective for ch.nging th.se beh.viors, and wh.th.r or not th.se devices or accompanying applications (apps) are feasible or desired veh.cles for beh.vior ch.nge. Four focus groups were conducted with.students from a Western university wh. were given iPads to download diet-related apps. Participants were asked questions about preferences regarding iPad functionality, app functionality, and th. likelih.od of using apps and iPads for facilitating diet-related beh.vior ch.nge in th. future. Two key th.mes emerged from focus group discussions on diet-related apps for iPads and th.ir usefulness to facilitate beh.vior ch.nge. Th. first th.me, lack of iPad practicality, contained th.ee subth.mes: inconvenient mid-way tech.ology, internet access barriers, and smart-ph.ne preference. Th. second th.me th.t emerged was attitudes towards apps in general. Th.ee subth.mes were identified under th. second th.me: too intensive;positive functions not specific to iPads;and lack of reliable/trustworth. information. Th.s paper is th. first, to th.s auth.r’s knowledge, to report th. use of qualitative meth.ds to study th. practicality of using apps and iPads in ch.nging dietrelated beh.viors. Early generations of iPads may not be effective devices for facilitating beh.vior ch.nge among college students;and diet-related apps seem to h.ve poor functionality th.t lead to cessation of use.
