PMID 37276459WHAT IT FOUND
The PPVT and ROWPVT did not differ in standard scores or age equivalents in preschoolers with and without hearing loss.
Either test can be used, but children with hearing loss scored lower than children with normal hearing.
Key findings
01The PPVT and ROWPVT did not differ in standard scores or age equivalents.
02Children with normal hearing had higher standard scores and higher age equivalents than children with hearing loss.
03Standard scores and age equivalents were higher at the second assessment than at the first.

What it does not show
Socioeconomic information was provided by only about half of families, so the sample may not represent all families. Hearing thresholds were not obtained, so the exact degree of hearing loss was not known. The tests were normed on children with normal hearing, which may not fully represent vocabulary development in children with hearing loss. Only the first and second assessments were analyzed, so the study cannot determine longer-term vocabulary growth or catch-up. The sample was not racially, ethnically, or socioeconomically diverse enough to examine how those factors relate to vocabulary. The hearing-aid and cochlear-implant comparison included 17 children with hearing aids and 11 children with cochlear implants, so it does not cover all children with hearing loss.

The easy way to misread this
Do not read the lack of test differences as evidence that hearing loss does not affect vocabulary. The children with hearing loss scored lower than the children with normal hearing on both tests, and the study cannot show which test is more accurate for children with hearing loss.
