Applying information visualization techniques to capture and explore the course of cognitive behavioral therapy

Tracking and especially comparing psychotherapeutic processes is a complex task involving a large number of individual and complexly related parameters. Therefore, descriptive and classical statistical methods are only suited for partial analyses. To overcome these limitations we introduce LinkVis, a new Information Visualization (InfoVis) tool used to visualize and evaluate psychotherapeutic processes. LinkVis is developed and clinically tested on the basis of Cognitive Behavioral Therapy treating anorectic girls. The user gets new insight into the data under investigation due to the combination of three different visualization techniques: scatterplots, Chernoff faces, and parallel coordinates. LinkVis supports exploring of complex time-dependent data in order to gain more information about the psychotherapeutic process, especially when comparing different patients and groups.
