Note. Part I of the GHADP (Gatehouse, 1999) assessed self-reported use (“What proportion of time do you use your hearing aid?”) and residual disability (“With your hearing aid, how much difficulty do you have?”) with participants' existing conventional hearing aids. Higher percentage scores are indicative of greater use/residual disability. GHADP = Glasgow Hearing Aid Difference Profile.
