The LittlEARS Auditory Questionnaire is designed to assess the development of the auditory behavior in children during the first two (hearing) years. The questionnaire has been validated on children with normal hearing whose native language is German. A comparison was made between North American English speaking children with normal hearing and found that it was consistent with the German data. This study is to validate the questionnaire in children with cochlear implants.

Further study details as provided by Med-El Corporation:

Primary Outcome Measures:
  • To validate the LittlEARS Auditory Questionnaire in hearing impaired children. The item analyses, scale analysis, analysis of expected values and minimal values have to be calculated, as it was performed with the US validation study. [ Time Frame: 24 months ]

Secondary Outcome Measures:
  • To determine if there are differences in statistical parameters between normal hearing children and hearing impaired children [ Time Frame: 24 months ]
  • Longitudinal assessment of cochlear implanted children over 24 months after first CI fitting [ Time Frame: 24 months ]
  • To establish the first words understood by a child with a cochlear implant [ Time Frame: 24 months ]
  • To establish the first words spoken by a child with a cochlear implant [ Time Frame: 24 months ]
  • To establish a sequence of word development [ Time Frame: 24 months ]
  • To compare words and word categories in different languages [ Time Frame: 24 months ]
