3 Simple View of Reading R= D X C R = Reading comprehension D = decoding words C = linguistic competence

4 What abilities are important during early reading? Phonological Awareness Language Literacy

5 Research questions 1.What are the components of DHH children’s early reading skills? 2.Are our assessments valid and reliable indicators of our proposed constructs? 3.Does the structure depend on what language acquiring? (ASL, Spoken English, both)

6 Sample Eligibility criteria – Kindergarten through second grade – At least a 45 DB loss BE-PTA or a cochlear implant – No severe disabilities as reported by teacher Variety of settings—state schools for the deaf, private schools, public schools Schools-Sample of convenience Children representative of school populations

7 Sample

8 Diverse sample N = 318 children 39% have a cochlear implant 27% have at least one deaf parent 53% white,15.5% African-American, 7% Asian, 3% Native American or Alaskan Native Ethnically---34% Hispanic 53% girls

9 Teacher report Type of class 68 % self-contained (DHH only) classrooms 15% inclusion (with hearing students) 14% taught a resource class N = 128 teachers

10 Language used in Classroom Spoken English41% ASL and spoken English20% ASL17% ASL, spoken, and signed English12% Spoken and signed English7% ASL, signed English2% Signed English0

11 Sample n =318 Mode/Languagen Sign136 Spoken English106 Spoken and Sign75

12 Assessment Protocol Details available from www.clad.gsu.edu Children were assessed on a large battery of tests in the fall Assessments were primarily adapted for those used with hearing children

13 Language Battery Vocabulary – Expressive One Word Picture Vocabulary Test – WJ Expressive Vocabulary Language comprehension – CASL passage comprehension (done in “best language) English Syntax Tests spoken or signed – Test of Auditory Comprehension of Language-3 --receptive – Clinical Evaluation of Language Functions-4 Word structure-productive ASL Syntax – Schick ASL Receptive Test

14 Language Do these assessments that measure very different aspects of language measure one underlying construct? Does this construct differ for children who use spoken language, signed language, or both?

15 Statistical Methods Confirmatory factor analysis using Mplus Examined model fit for each of the latent constructs – For whole sample – For three subsamples defined by mode/language Model fit determined by CFI, TLI, SRMR

16 Signing Children CELF- word structure did not load on factor

17 Bilingual Children CELF- word structure did not load on factor

18 Spoken language children

19 Phonological Awareness Spoken Phonological Awareness – Comprehensive Test of Phonological Processing Blending Elision Sound Matching – WJ Word attack Fingerspelling PA Schick FS-PA Test – Imitation – Blending – Elision

20 Spoken and bilingual children

21 Signing Children

22 Literacy battery Woodcock Johnson-III Letter word ID Passage Comprehension Writing Fluency Reading Fluency Spelling

23 Whole Sample

24 Structure of Early Reading Literacy Phonological Awareness Language Code- Related Skills or Language

25 Spoken and bilingual

26 Signing Children

27 Conclusions Assessments good measures of underlying constructs Structure of early literacy skills resemble those of hearing children But nature of sublexical skills and language unique to DHH children, especially those who sign Is PA more important than language? Wrong question—given high intercorrelations
