The purpose of this study was to examine the involvement of grandparents during hearing detection and intervention. Data were collected and analyzed from survey responses of 50 parents and 35 grandparents of children of varying ages who have hearing loss. Parents described important types of support that grandparents provided including frequent emotional support, nurturing, and spending time together. Grandparents reported that they frequently implemented therapy strategies with their grandchild, but did not attend therapy sessions. Results of this study provide recommendations for service providers and information about the supportive role of grandparents in hearing detection and intervention. (Contains 4 tables.)
