What is it?
The DOSO questionnaire was developed to measure hearing aid outcomes in a manner that is relatively independent of wearer personality. In most of the items, patients choose from several responses to indicate how well the hearing aids work to accomplish specific goals. The DOSO produces scores for 6 sub-scales: Speech Cues, Listening Effort, Pleasantness, Quietness, Convenience, and Use. There are two short forms [DOSOs(a), DOSOss(b)] and one long form (DOSO) available for use. DOSOs (a) and DOSOs(b) each consist of 28 items. The difference between DOSOs(a) and DOSOs(b) is the items in the Speech Cues and Listening Effort sub-scales. DOSOs(a) and DOSOs(b) are equivalent forms and both produce scores for all 6 sub-scales. The long form DOSO comprises all 40 items and produces scores for all 6 sub-scales. DOSOs(a) and DOSOs(b) have been revised in order to keep up with changes in rechargeable technology.
