The study examined 448 children with bilateral hearing loss, ages 8 to 39 months, across 12 states, and is the first multi-state study to assess EHDI 1-3-6 guidelines (hearing screening by 1 month, diagnosis of hearing loss by 3 months and intervention by 6 months). Researchers found that the children who had met all three benchmarks developed significantly higher vocabulary quotients.
Those with hearing loss who had met the guidelines and had no additional disabilities had an average vocabulary quotient (VQ) score of 82, which is considered the low end of normal range. The expected mean score of hearing children is a VQ of 100. Children who had not met all the guidelines scored less than 70, falling below the 10th percentile.

Researchers found that the children who had met all three components of the EHDI guidelines developed significantly higher vocabulary quotients.

“Because the brain is so pliable in those early months, the sooner we can get them diagnosed and get them access to language, the more likely they will be able to develop on track with their peers,” says lead study author Christine Yoshinaga-Itano, an audiologist and research professor in the Institute of Cognitive Science at the University of Colorado Boulder.
However, the study authors also note that only 58 percent of the children in the study had met the 1-3-6 guidelines. “Policymakers need to do whatever they can to make transitions from one step to another as seamless as possible, so parents can meet the 1-3-6,” says Yoshinaga-Itano.
