A Tool That Supports the Psychologically Based Design of Health-Related Interventions

This paper offers a holistic and psychologically oriented perspective on health recommender systems and introduces a tool— CHUSAPEDIA—that is designed to support researchers and practitioners in putting this perspective into practice. One component of CHUSAPEDIA is a semantic wiki in which a wide range of knowledge is formalized about how people make choices and how these choices can be supported. The second component is a web application that accesses the knowledge in the semantic wiki to help designers to create choice support interventions of various types. In the paper, a starting point is a consideration of the strengths and limitations of the most advanced existing comparable resource, the Behavior Change Technique Taxonomy of Michie et al. An example of an analysis performed with CHUSAPEDIA then briefly illustrates the benefits offered by the tool, which will be demonstrated at the workshop and made available to all workshop participants.
