    Formative evaluation of a mobile liquid portion size estimation interface for people with varying literacy skills
    (Springer Berlin Heidelberg, 2013-12) Chaudry, Beenish Moalla; Connelly, Kay; Siek, Katie A.; Welch, Janet L.; IU School of Nursing
    Chronically ill people, especially those with low literacy skills, often have difficulty estimating portion sizes of liquids to help them stay within their recommended fluid limits. There is a plethora of mobile applications that can help people monitor their nutritional intake but unfortunately these applications require the user to have high literacy and numeracy skills for portion size recording. In this paper, we present two studies in which the low- and the high-fidelity versions of a portion size estimation interface, designed using the cognitive strategies adults employ for portion size estimation during diet recall studies, was evaluated by a chronically ill population with varying literacy skills. The low fidelity interface was evaluated by ten patients who were all able to accurately estimate portion sizes of various liquids with the interface. Eighteen participants did an in situ evaluation of the high-fidelity version incorporated in a diet and fluid monitoring mobile application for 6 weeks. Although the accuracy of the estimation cannot be confirmed in the second study but the participants who actively interacted with the interface showed better health outcomes by the end of the study. Based on these findings, we provide recommendations for designing the next iteration of an accurate and low literacy- accessible liquid portion size estimation mobile interface.

    Using a Mobile Application to Self-Monitor Diet and Fluid Intake among Adults Receiving Hemodialysis
    (Wiley, 2013) Welch, Janet L.; Schafer Astroth, Kim; Perkins, Susan M.; Johnson, Cynthia S., III; Connelly, Kay; Siek, Katie; Jones, Josette; LaRue Scott, Linda; School of Nursing
    Hemodialysis patients have difficulty self-managing a complex dietary and fluid regimen. The purpose of this feasibility study was to pilot test an electronic self-monitoring intervention based on social cognitive theory. During a six-week intervention, 24 participants self-monitored diet and fluid intake using the Dietary Intake Monitoring Application (DIMA), and 20 participants served as controls by monitoring their activity using the Daily Activity Monitor Application (DAMA). Results from this pilot study suggest the intervention is feasible and acceptable, although few significant effects on outcomes were found in this small sample. The DIMA has potential to facilitate dietary and fluid self-monitoring but requires additional refinement and further testing.
