OBJECTIVE With the advent of personal health records and other patient-focused health technologies, there is a growing need to better understand factors that contribute to acceptance and use of such innovations. In this study, we employed the Unified Theory of Acceptance and Use of Technology as the basis for determining what predicts patients' acceptance(More)
The common sense model (CSM) shows how people process information to construct representations, or mental models, that guide responses to health threats. We applied the CSM to understand how people responded to information about arsenic-contaminated well water. Constructs included external information (arsenic level and information use), experience(More)
This research employed a participatory approach to explore environmental health (EH) concerns among Lac Courte Oreilles (LCO) Ojibwa Indians in Sawyer County, Wisconsin. The project was grounded in a broad ecological conceptualization of EH and in principles of health promotion and community participation. Community participation was accomplished through a(More)
Lay people have difficulty understanding the meaning of environmental health risk information. Visual images can use features that leverage visual perception capabilities and semiotic conventions to promote meaningful comprehension. Such evidence-based features were employed to develop two images of a color-coded visual scale to convey drinking water test(More)
OBJECTIVES The purpose of this paper is to describe biomedical informatics training at the University of Wisconsin-Madison (UW-Madison). METHODS We reviewed biomedical informatics training, research, and faculty/trainee participation at UW-Madison. RESULTS There are three primary approaches to training 1) The Computation & Informatics in Biology &(More)
Theory-based research is needed to understand how people respond to environmental health risk information. Both the common sense model (CSM) of self-regulation and the mental models approach propose that information shapes individuals' personal understandings that, in turn, influence their decisions and actions. We compare these frameworks and explain how(More)
Because lead exposure is a health-related condition that precedes elevated blood lead levels, the aims of this study were to examine the prevalence of lead exposure among children attending lead screening clinics in two Wisconsin counties and to explore its relationship to demographic variables. Based on data obtained from parents, significant relationships(More)
Theory-based research is needed to understand how maps of environmental health risk information influence risk beliefs and protective behavior. Using theoretical concepts from multiple fields of study including visual cognition, semiotics, health behavior, and learning and memory supports a comprehensive assessment of this influence. The authors report(More)
To test a theoretical explanation of how attributes of mapped environmental health hazards influence health-related behavioral intentions and how beliefs and emotion mediate the influences of attributes, 24 maps were developed that varied by four attributes of a residential drinking water hazard: level, proximity, prevalence, and density. In a factorial(More)
Successful field evaluation of informatics initiatives designed to create technology-enhanced professional practice relies on adequate training of experimental participants. However, such training presents design, implementation and evaluation challenges. A macroergonomic approach, focusing on an organizational view of people, technology, task and(More)
