Abstract

An important factor in the eectiveness of virtual health
agents is the extent to which they are perceived as human-like. This perceived human-likeness (anthropomorphism) could create expectations about the agent's abilities. However, the concept anthropomorphism is interpreted in dierent ways, leading to dierent operationalizations. This paper discusses dierences between those interpretations and proposes a measuring instrument for anthropomorphism based on the Rasch model. This instrument tests whether or not certain human-like characteristics are attributed to a virtual agent. Data from a number of studies are presented to show the reliability and validity of using this method. Finally, the paper discusses the method's added value in the measurement of
anthropomorphism, as well as future steps to be taken.
