Content validity: The development and pre-testing of this questionnaire covered pre-defined phases collecting empirical data. Phase 1: A first version of the questionnaire was constructed and pre-tested by collecting qualitative data from 8 students. In a face-to-face setting; the students were observed and interviewed with a focus on their understanding of the questions and the response formats. Phase 2: After revising the test according to the results of the first phase, a quantitative field test was performed. This first field test aimed at getting information about the fit of the Rasch model to this kind of competency data and the appropriateness of the facet design of the test. Additionally, the response format, distractors, item difficulties and discriminations were analyzed, and the test instrument has been revised accordingly. Phase 3: A second field test was performed in order to control the improvement of the test instrument and the fit of the Rasch model. The development process was completed by the time the Rasch model was the best fitting model.
