International audience; Running long-term field studies is a valuable yet slow and costly approach to test the efficacy of interaction designs on people's everyday decision making and behavior. In this position paper we describe the rationale behind an interdisciplinary approach to designing and evaluating data-driven interactive experiences for sustainable decision-making. We are a group consisting of HCI and visualization researchers, energy-economy modeling experts who work on mitigation pathways, and behavioral economists who run controlled experiments to study how people make decisions in an incentivized context. The intent of this collaboration is twofold: (1) we study how to design efficient data-driven experiences to help people build an intuition concerning the sustainability of daily choices and actions; (2) we explore the mutual benefit of working across disciplinary boundaries to go beyond the limits of our respective methodological toolboxes. We illustrate our approach through an example of a work-in-progress.

The project aims at examining whether people are more likely to lie when facing a shared resource whose level can vary. There are many examples of individuals facing a shared resource (fishes school, water for irrigation...). When facing a shared resource, it is important that people take into account the remaining level of the resource before exploiting it if not the resource can be destroyed. Sometimes people engage in dishonest and illegal activities to derive more benefits from the resource at the expense of other people (fishing more than authorized...). We aim at examining whether dishonesty is modulated by the remaining level of the resource. Are people more likely to misbehave when facing a very limited shared resource? a resource whose level can guarantee benefits for every member?

Objectives: Because of the fluctuating and occasional character of Crohn’s disease (CD), patients have to cope with a changeable condition of health. Personal perceived control is known to be an important element of adaptation to their medical condition. The objectives of this work are to determine if perceived personal control is predictive of the clinical activity of the disease and of psychological distress (depression, anxiety). Methods: The Hospital Anxiety Depression Scale (HADS), the causal dimension scale and the Clinical Global Impression (CGI; assessing perceived severity) were administered to 160 patients affected by Crohn’s disease. Indicators of inflammation (CRP), disease duration and clinical activity of the disease were also asessed. Results: Globally, CD patients perceive their disease as being personally neither controllable nor uncontrollable. Whereas psychological distress is significantly higher when the disease is active, the relationship between the variables appears complex. The feeling of personal control is explained by the clinical activity of the disease (p=.0001) and by the perception that CD is unstable (p, GMS Psycho-Social-Medicine; 10:Doc08; ISSN 1860-5214
