Bringing the Computer-Based Instrument for Low Motor Language Testing to Canada: A Survey of Caregiver and Clinician Perspectives.

PMID 41456947WHAT IT FOUND
Canadian caregivers and clinicians say current language comprehension assessments for children with cerebral palsy lack accuracy, creating a critical gap.
Both groups view the new C-BiLLT-CAN tool as highly promising, but flag that it currently lacks the response methods, like auditory access and specific switches, that many children need to actually complete the test.
Key findings
01Clinicians rely almost entirely on non-standardized tools like observation and parent interviews because they have little confidence in standardized tests for this population.
02Caregivers and clinicians anticipate the C-BiLLT-CAN would significantly improve assessment accuracy and service provision, though clinicians worry about costs and the need for prior proficiency with access methods.
03Participants identified several response methods currently missing from the C-BiLLT-CAN that are essential for participation, including auditory access, mechanical switches with joysticks, and contact access.

What it does not show
The sample was small and demographically homogeneous, mostly consisting of Caucasian, postsecondary-educated participants in Ontario, which may not represent all Canadian families or clinicians. The study relied on self-reported perceptions and hypothetical impacts rather than measuring actual clinical outcomes or test performance with children. Response bias is possible because the survey was anonymous and non-respondents were not followed up, potentially skewing results toward those already optimistic about the new tool.
Declared interests
One author is a co-creator of the C-BiLLT and chairs the foundation that develops it. Another author provides training for the Norwegian version. The research was funded by the Canadian Institutes of Health Research.
The easy way to misread this
Do not assume the C-BiLLT-CAN is ready for widespread clinical use in its current form. The survey reveals that a significant portion of children with CP and SSPI cannot complete the test because it lacks necessary response methods like auditory access or specific switch compatibility, meaning a null result might reflect an access barrier rather than a lack of comprehension.
