Do experienced hearing aid users know how to use their hearing aids correctly?

Purpose: To assess experienced hearing aid users' ability to use their hearing aids correctly. Method: In this study, we developed the Practical Hearing Aid Skills Test (PHAST) to objectively test a hearing aid user's ability to manipulate his or her hearing aids. The PHAST requires hearing aid users to perform 8 hearing aid care and use tasks that are basic skills typically taught to new hearing aid users at the time of their hearing aid fitting. The PHAST was administered to a group of 50 experienced hearing aid users. In addition, participants were administered questionnaires about hearing aid satisfaction (i.e., Satisfaction With Amplification in Daily Life; R. M. Cox & G. C. Alexander, 1999), benefit (i.e., Abbreviated Profile of Hearing Aid Benefit; R. M. Cox & G. C. Alexander, 1995), and use. Results: Participants' performance on the PHAST ranged from 48% to 100%, and the scores were normally distributed around the mean (78.56%). No significant relationship was observed between the PHAST and any of the other tests administered in this study. The only variable significantly associated with participants' performance on the PHAST was age. Conclusions: Results from this study suggest that experienced hearing aid users range from having an excellent understanding of how to use their hearing aids to a poor understanding. The variability in performance among experienced hearing aid users highlights the importance of directly assessing a client's ability to use his or her hearing aids.
