En granskning av det internationellt använda frågeformuläret International Outcome Inventory for Hearing Aids (IOI-HA).

Abstract

Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.

The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.

The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures. In all the studies the results showed two factors according to the seven questions.

The four studies and the pilot study showed that IOI-HA was good to discern satisfied and non-satisfied patients. The result of the pilot study indicates a high score which means that the patients are satisfied with their hearing aids.
