This study focussed on self-report outcome in new hearing-aid users. The objectives of the experiment were changes in self-report outcome over time, and relationships between different subjective measures of benefit and satisfaction. Four outcome inventories and a questionnaire on auditory lifestyle were administered to 25 hearing-aid users repeatedly after hearing-aid fitting, and assessments took place one week, four weeks, and 13 weeks after hearing-aid provision. The results showed that, for first-time users who used their hearing aids more than four hours per day, self-reported outcome increased over 13 weeks in some scales, although there was no change in amplification during this time. Furthermore, it was found that, for data collected immediately post-fitting, some subscales were much less face valid than for data collected later. This result indicates that the way in which hearing-aid users assess outcome changes over time. The practical consequence of the results is that early self-report outcome assessment may be misleading for some self-report outcome schemes.
