Abstract
Increasingly popular touch-screen electronic tablets offer clinics a new medium for collecting adolescent health screening data in the waiting area before visits, but there has been limited evaluation of interactive response modes. This study investigated the clarity, comprehensibility, and utility of icon-driven and gestural response functions employed in one such screening tool, TickiT. We conducted cognitive processing interviews with 30 adolescents from Vancouver (aged 14-20 years, 60% female, 30% English as a second language) as they completed the TickiT survey. Participants used seven different interactive functions to respond to questions across 30 slides, while being prompted to articulate their thoughts and reactions. The audio-recorded, transcribed interviews were analyzed for evidence of comprehension, nuances in response choices, and youth interest in the modes. Participants were quite receptive to the icon response modes. Across demographics and cultural backgrounds, they indicated question prompts were clear, response choices appropriate, and response modes intuitive. Most said they found the format engaging and would be more inclined to fill out such a screening tool than a paper-and-pencil form in a clinical setting. Given the positive responses and ready understanding of these modes among youth, clinicians may want to consider interactive icon-driven approaches for screening.
