BESA: Content validity

Last month I posted saying I was working on the validity analyses for the Bilingual English Spanish Assessment (BESA) that is hopefully soon to be published and available for clinicians. Today, I’ll tell you a little about the results. As many of you know, a number of years ago we (Vera Gutierrez-Clellen, Aquiles Iglesias, and I) got an NIH contract to explore typical and atypical speech and language development in Spanish-English bilingual children. Brian Goldstein and Lisa Bedore joined our team about a year later. The results of the 7 year project were to have a measure that would identify bilingual children with language impairment and phonological impairment.

Testing bilinguals in English: Do we get any useful information?

I think the title says it all, and it’s an important question. There’s no doubt that the best way to determine if a child has a language impairment is to test them in their language. For bilinguals, that usually means two languages– in the US context, their home language and English. But, there aren’t enough bilingual speech-language pathologists available nationally; and bilingual speech-language pathologists don’t speak every language represented by the clients in their area. So, one of the questions we’ve had is whether we can get any useful information from testing children who are bilingual in English only. The quick answer is yes, no, and it depends. The longer answer follows.
