An important factor in the effectiveness 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 different ways, leading to different operationalizations. This paper discusses differences 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.
