Recruiting for Infant Study

The UNC Craniofacial Center is conducting a longitudinal research study on infant speech development following cleft palate repair. We are currently seeking infants without cleft lip or palate and without a history of ear tubes or frequent ear infections to serve as a comparison group.

To be eligible for the study, infants must:

  • be between 9  and 12 months of age
  • be learning English as a first and only language
  • not have developmental delays
  • not have known syndromes
  • not have known sensory-neural hearing loss
  • pass a screening procedure

The study will occur at the UNC Craniofacial Center. If your infant passes the screening we will video tape you and your child during play activities, record his/her speech (babbling), monitor his/her nasal breathing using a simple technique, and screen middle ear function and hearing. For visits 4 and 7 we will also ask you to complete an inventory of the words and phrases that you hear your child saying. The study may require as few as 4 visits or up to 7 visits during the first year (approximately every two months) and a single visit at 36 and 48 months of age. Each visit will take approximately 1 to 2 hours. We will compensate you from $310 to $510 over the 3 years of the study depending on the number of visits and procedures completed. We will also reimburse you for parking and mileage if greater than 10 miles roundtrip.   

This study is funded by the NIDCR and has been approved by the University of North Carolina at Chapel Hill Institutional Review Board (Study # 12-2252, approval date 6/12/13). Dr. David Zajac is the principal investigator.
