It is increasingly understood how fun is an essential aspect in interaction for children in or beyond game play, as well as supporting learning and other activities involving children, e.g., for participatory design. While it is often proclaimed that such activities are fun for children participants, empirical evidence is hard to come by as measuring fun is not straightforward. Currently available assessment tools suitable for adolescents are scarce. FunQ is a recently developed measurement tool specifically designed for adolescents for the assessment of the experienced fun. Here we discuss ongoing work for adapting FunQ - to Spanish and Dutch. We report on the process followed to adapt the questionnaire; the reliability measures based on the initial results (ωoverall-SP= 0.876 and ωpartial-SP= 0.859; ωoverall-NL= 0.819 and ωpartial-NL= 0.804); and discuss our findings in reflection of the current state of the adaptation procedure.
