In terms of terminology, whe rest of the world outside the UK and Ireland use CAS as their preferred term. At present, UK therapist generally use ‘features of DVD’ in line with the RCSLT policy statement on DVD. However, the Child Speech Disorder Research Network (CSDRN) are trying to discuss this with RCSLT, as the statement really needs an update as it is now 10 years old, and lots of new evidence has recently emerged. We also with to reconsider the guidance re terminology. Pam Williams and myself were the main authors of the original policy statement and are members of CSDRN, so are leading the push for the update. Clinically, I now use both terms – typically saying ‘in the UK we use DVD as the term, but hopefully we will soon align with the rest of the world who use CAS’. This then enables colleagues and families to access the most recent recearch which is being conducted in the USA and Australia. Interestingly, this is also a discussion that IASLT (Irish association) are also having. I suspect we will feature something in RCSLT Bulletin in the (hopefully) near future. Do bear in mind that DVD/CAS is often overdiagnosed, since less than 0.1% of kids with speech difficulties from no known cause have DVD/CAS. In contrast, 10% will have inconsistent phonological disorder, along with 10% articulation, 20% consistent phonological disorder and 60% phonological delay.
Best of luck!
