Psychometric properties of a revised Danish translation of the international outcome inventory for hearing aids (IOI-HA).

Objective: The original Danish translation of the international outcome inventory for hearing aids (IOI-HA) proved problematic as the wording of item 5 was not semantically clear, rendering the questionnaire internally inconsistent. The objective of this study was to examine data collected with a revised Danish translation of the IOI-HA in order to: (1) evaluate the effect of the revision, and (2) to examine if the psychometric properties of the revised translation of the IOI-HA are equivalent to those of previously validated translations.

Design: Psychometric properties were evaluated performing inter-item correlation analysis, principal component analysis, and item-total correlation.
