Abstract

With the motivation of investigating the replicability and transferability of the findings employing the Facilitative Interpersonal Skills (FIS) performance task beyond Anglophone countries, a set of Dutch FIS clips have been scripted and recorded. In this study the psychometric properties of the Dutch clips was tested. Furthermore, an additional set of FIS clips portraying a non-challenging client-therapist interaction was tested. 369 psychology students rated the interpersonal impact (IMI-C) and the affect (positive and negative affect schedule) displayed by the hypothetical client. Thirteen out of sixteen FIS clips were located in the same IMI-C quadrant as the US clips, indicating good content validity for all sets of FIS clips. Inter-rater reliability was reasonable for one set of Dutch language FIS clips (k=0.416). Visual inspection of quadrants showed the different character of the non-challenging set of FIS clips. The Dutch FIS clips are directly applicable for educational and research purposes.
