Subclaims¶

q3 i? 68% achieved a CELF-4 Language Content Index within or above 1 SD of hearing age-mates; 71% scored in range on PPVT in SC administration (66% OC) and 74% on the EOWPVT. → Geers Ann E. 2011

Results section reports the standardized language battery for the CI-HS sample (n = 112): CELF-4 Language Content Index mean 92.1 with 68% within normal limits; PPVT mean 90.3 (OC) and 93 (SC); EOWPVT mean 91.4 with 74% in range. In a normal distribution 84% would be expected in this range.

"Sixty-eight percent of the sample achieved a Language Content Index within or above 1 standard deviation of NS-TD age-mates. The most challenging subtest was Understanding Spoken Paragraphs (Mean scaled score = 7.6)"
