This article presents a methodological study in which an assessment procedure of translational creativity is tested. The study was conducted in the context of an empirical investigation into the development of translational creativity (Bayer-Hohenwarter 2012). The creativity assessment procedure on which this empirical investigation relied used product data and process data (“combined approach”). Some of the process data were think-aloud (TA) data. The article discusses the ways in which TA can influence the results of this assessment procedure and which alternatives could have been used. As a purely product-oriented approach is considered to be largely free from TA influence, the combined approach is compared with the purely product-oriented approach. This is to find out whether the results from creativity assessments according to the two approaches match. The results indicate convergent creativity scores, certain methodological risks, but also several benefits of the combined approach.
