Method for Developing Communication Skills in Autism - DHACA: appearance and content validation.
Ana Cristina de Albuquerque Montenegro, Amanda Gabrielly de Santana Silva, Bianca Queiroga and 2 others
PMID 38126457WHAT IT FOUND
Ten speech-language-hearing judges rated the DHACA autism communication book suitable in appearance and content.
They suggested colored pictogram backgrounds and replacing this and that with my and your. This checks design, not patient outcomes.
Key findings
01The book's appearance was rated representative by five judges and very representative by five in both rounds.
02The whole instrument reached 99% agreement, above the 90% threshold.
03Experts changed the book to color core pictogram backgrounds by part of speech and replace 'this' and 'that' with 'my' and 'your'.

What it does not show
Only ten speech-language-hearing judges took part. The study checks expert ratings of appearance and content, not communication outcomes in children with autism. The method is not indicated for children without minimum shared attention, good fine motor coordination, normal eye-hand coordination, or without intellectual or visual disability. The paper does not report funding or conflicts of interest.
The easy way to misread this
Do not read this as evidence that DHACA improves communication in children with autism. It reports only that ten speech-language-hearing judges found the method's appearance and content suitable.
