Reliability and Validity of the Dutch Language Version of the CFCS-NL and the VSS-NL in Flanders, Belgium
An observational study of Cerebral Palsy and Communication, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.
Trial summary
The study aims to determine the reliability and validity of the CFCS-NL and VSS-NL (both speech and language-related classification scales for children with cerebral palsy) for Flanders so they can be implemented within the CP-referencecentre at UZ Leuven, amongst the classification scales that are already being used.

About this study
Official title: Reliability and Validity of the Dutch Language Version of the Communication Function Classification System (CFCS-NL) and the Viking Speech Scale (VSS-NL) in Flanders, Belgium
The study aims to determine the reliability and validity of the CFCS-NL and VSS-NL (both speech and language-related classification scales for children with cerebral palsy) for Flanders so they can be implemented within the CP-referencecentre at UZ Leuven, amongst the classification scales that are already being used.
Read the detailed description
Within the CP-referencecentre, the gross motor (GMFCS), fine motor (MACS) and swallowing (EDACS) skills have of children witch cerebral palsy (CP) have long been classified. In the speech and language pathology field, the Communication Function Classification Scale (CFCS) and the Viking Speech Scale (VSS) were recently developed. The CFCS maps communication as a whole and is a five-point scale. The CFCS is analogous to the aforementioned scales. The VSS focuses on speech intelligibility and is a four-point scale.
This research is based on determining the reliability and validity of the above scales for Flanders so that they can be implemented within the CP-referencecentre. In addition, the mutual relationship between the scales and the relationship between the CFCS-NL and the other classification scales for CP (GMFCS, MACS \& EDACS) will be determined. The VSS will also be translated into Dutch beforehand, this is a collaboration with the VU University Amsterdam (dr. Joke Geytenbeek).
The study is a cross-sectional study. The patients (n = 20) will be recruited during the consultations at the CP-referencecentre between February 1, 2019 and April 30, 2019. The selection criteria consist of: diagnosis of CP, age of 4 t.e.m. 10 years, single language education in Dutch, no diagnosis of ASD and a signed Informed Consent Form.
A questionnaire bundle will be given to the parents of the participating patients (completion time approx. 30 to 45 minutes). This includes a few questionnaires about characteristics of the child / filler, two questionnaires about the social communication skills and the social interaction skills of the child, and the CFCS and VSS scales which the parents have to score. This questionnaire bundle (with the exception of the questionnaires concerning social communication skills and social interaction skills) will also be given to the child's teacher and a treating paramedic. In addition, an appointment will also be made at the patients house where a video recording (2x15min) will be made in which the child interacts with a trusted person and an untrusted person (the researcher) so that the CFCS- NL and the VSS-NL scores of the child can be determined by the student and the speech therapists of the CP-referencecentre. During that appointment one of the parents will also be interviewed using the subdomain "Social Functioning" of the PEDI-NL.
After data collection, a quantitative data analysis is performed to obtain an answer to the research questions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Observation at home.Other
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Reliability and validity of the CFCS-NL and the VSS-NL
The inter-rater-reliability of the CFCS-NL and the VSS-NL (which are described above in the descriptive section) will be measured by comparing the classification scores given by the different groups of people who classified the child, using Cohen's Kappa.
The validity of the CFCS-NL and the VSS-NL will be measured by comparing the scores with the total score on the section 'Social Functioning' of the PEDI-NL, using a Spearmans rho.
Measured: The scores will be collected over a timeframe of 5 months (may - september).
Secondary outcomes (2)
Correlation between CFCS-NL and the VSS-NL

Questions about this trial
What is this clinical trial studying?
An observational study of Cerebral Palsy and Communication, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Reliability and validity of the CFCS-NL and the VSS-NL (time frame: The scores will be collected over a timeframe of 5 months (may - september).). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04500782, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Aug 2020; AzTrials last refreshed its copy on 6 Nov 2026.
