Measuring hearing aid outcomes using the Satisfaction with Amplification in Daily Life (SADL) questionnaire: Australian data.

The aims of this study were to investigate hearing aid satisfaction for a group of older Australians fitted with government-funded hearing aids using the Satisfaction with Amplification in Daily Life (SADL) questionnaire; to compare the Australian data gathered with the provisional normative data reported by Cox and Alexander (1999); and to investigate the relationship between SADL satisfaction and several participant variables, hearing aid variables, and other outcome measures. The SADL questionnaire and a Client Satisfaction Survey (CSS) were distributed by mail to 1284 adults fitted with government-funded hearing aids three to six months previously. 1014 surveys were returned.
