Reliability and Validity of the Dutch Language Version of the CFCS-NL and the VSS-NL in Flanders, Belgium

An appointment will be made at home, first one of the parents will be interviewed using the 'Social Functioning' subdomain of the PEDI-NL (Ostensjo, Bjorbaekmo, Brogren Carlberg, \& Vollestad, 2006) to determine the validity of the CFCS-NL and the VSS NL . This section contains some aspects that question the communication skills. The PEDI-NL was chosen as there is no gold standard to investigate functional communication in people with CP. Most standardized test and observational instruments only investigate language comprehension and / or language production and are furthermore developed for normally developing children. On the other hand, a video recording will be made in which the child interacts with a relative and an unknown person (the researcher) so that the CFCS-NL and VSS-score can be determined by the student and the speech therapists of the CP reference center.
