    HamkeRun: Mobile infoVis app towards sustainable motivation in a context of running
    (2015-05) Moon, Sung Pil; Bolchini, Davide; Pfaff, Mark; Rand, Kevin; Voida, Stephen
    According to the US Centers for Disease Control and Prevention, less than half of all adults in the US meet basic physical activity guidelines. Physical activity can help not just improve physical and mental health but also reduce the risk of heart disease and some cancers. Researchers and companies have tried to investigate the use of modern technologies to motivate people to increase and maintain physical activities. However, in spite of these efforts, there are criticisms. Those include low dietary effectiveness of the tools, lack of sustainable effects in the long-term, and proof of effectiveness only shown in laboratory settings. To overcome these limitations, first, the author developed a framework of overarching motivation theories and HCI factors and contextualized it within the running domain. Second, the author has developed a mobile application called HamkeRun within this framework, using the concepts of information visualization, gamification, and social grouping to increase a user’s motivation to run more frequently. Third, the HamkeRun application was empirically tested through a two-month-long longitudinal experiment and follow-up interviews. The results showed that the single runner type showed significant increases in the levels of their external motivation (motivational effect of the HamkeRun application), internal motivation and satisfaction, while the team runner type showed significant increases only in internal motivation. In addition, motivational effects were also different depending on the runners’ behavior change stage. Runners at the maintenance stage showed significant increases in external motivation, internal motivation, satisfaction, and total number of running activities performed during the study. Although action stage runners showed significant increase in internal motivation, female runners at the action stage showed significant decrease in their external motivation. Gamification greatly influenced increases of external motivation, internal motivation and total number of actual activities. Although both male and female runners showed increased internal motivation, significant increase in external motivation was only found in male runners. The dissertation closes with a series of design guidelines for application developers and designers which may help develop motivational tools in other health-related domains.

    The Impact of Stationary and Mobile Fetal Monitors
    (2018-04-29) McKinney, Jay; Christe, Barbara
    The work describes the utilization of stationary and mobile fetal monitoring. The work emphasizes the important uses of stationary and mobile fetal monitoring based off data collected to summarize the best utilization method. The work is intended to study the effects of stationary and mobile fetal monitors at two similar facilities.

    Nutrition Enhancement in Early Psychosis (Neep): A Feasibility Trial of Enhanced Nutrition with Text Messaging and a Dietary Tracking Mobile Application
    (2022-08) Fischer, Melanie W.; Salyers, Michelle; Minor, Kyle; Stewart, Jesse; Rivera, Rebecca; Leonhardt, Bethany
    Background. People with psychotic disorders tend to die earlier than the general population, primarily due to preventable cardiovascular disease. Behavioral risk factors, such as poor diet, have been identified as major contributors. Given the importance of prevention, the early stages of psychosis have been described as a “critical” time to intervene on health behaviors. As such, a mobile-based intervention, Nutrition Enhancement in Early Psychosis (NEEP) was created to improve diet quality in persons with early psychosis. This study has three aims: (1) assess the feasibility of the intervention, (2) examine preliminary outcomes, and (3) investigate mechanisms associated with dietary change. Methods. NEEP incorporates a combination of nutrition education, goal setting, and mobile technology (i.e., a mobile application for dietary tracking, as well both automated and personalized text-messages). Given the pilot nature of the study, all participants (N=15) received the intervention. Feasibility was assessed through different metrics related to recruitment and adherence to the dietary tracking application, as well as self-report responses regarding acceptability. Preliminary outcomes (i.e., two measures of diet quality) and potential mechanisms of change (i.e., self-efficacy and motivation) were also evaluated using paired sample t-tests. Qualitative interviews were conducted following study participation. Given the emphasis on feasibility with a small sample, all significance tests were set at p <.10, and Hedges g was used to examine effects over time. Results. 15 participants were enrolled in the study and 12 participants completed follow-up assessments. Evaluative measures of feasibility suggest that the majority of those who were screened enrolled in this intervention and regularly engaged with the mobile tracking device to record their dietary consumption. In addition, participants enjoyed the intervention and found it to be useful in improving their diet. Preliminary evidence also suggests this intervention may improve diet quality. As such, one indicator of improvement in diet quality was considered significant (Rapid Eating Assessment for Participants- Shortened; p=.084), and both measures of diet quality suggested improvement in diet at the end of the 28-day intervention with small to medium effect sizes (REAP-S g=.44; Heathy Eating Index-2015 g=.69). Contrary to hypotheses, self-efficacy significantly decreased after the intervention (p=.028) and motivation remained relatively stable. Conclusion. Results suggest that NEEP is feasible as a low-cost, low-resource mobile intervention that is well-tolerated and may improve diet quality in people with early psychosis; however, mechanisms of change require further exploration.
