Effects of an Intervention Designed to Increase Toddlers' Hearing Aid Use.

The purpose of this study was to examine the effectiveness of Ears On, an intervention designed to increase toddlers' use of hearing devices. A single-case, multiple-baseline design across participants was used with three parent-child dyads who demonstrated low hearing aid use despite enrollment in traditional early intervention services. Data logging technology was used to objectively measure hearing aid use. A functional relationship was identified between participation in the intervention and the number of hours children utilized their hearing aids. Two dyads met the criterion set for completing the intervention: an average of 8 hr of daily hearing aid use. One dyad did not reach this criterion but did meet the parent's goal of full-time use in the child's educational setting. For all dyads, increases in use were maintained 1 month after completion of the intervention. Findings support use of this short-term, intensive, individualized intervention to improve hearing aid use for toddlers with hearing loss.
