More about the Outcomes of Children with Hearing Loss study

The OCHL study was funded in 2008 by the NIH-NIDCD. The principal investigators, Mary Pat Moeller, PhD, and J. Bruce Tomblin, PhD, recruited a multi-disciplinary team of professionals from the University of Iowa, Boys Town National Research Hospital, and the University of North Carolina in the fields of audiology, speech-language, psychology, linguistics, and biostatistics to help support the project. The OCHL study focused on examining the impact of newborn hearing screening, early intervention, and advances in hearing technology on a wide range of developmental outcomes for children who are hard of hearing. This work has been a huge success, thanks to all involved, and our published findings will continue to be posted on the Publications page.

OCHL Study Assessments

Age-appropriate test batteries were developed for each age range from 6 months to 9 years. Domains of measures included:

  • Speech and language skills, including articulation, expressive and receptive language, narrative development, and theory of mind (social cognition).
  • Hearing, including an audiogram, speech perception, and hearing aid verification.
  • Academics, including pre-literacy and literacy skills, math, and nonverbal and verbal ability.
  • Psychosocial, including parental questionnaires of child behavior and temperament.
