This article is from International Journal of Audiology, volume 53.AbstractObjective: 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. Study sample: Three hundred forty-one adult hearing-impaired participants—all of whom were voluntary hearing aid testers attached to the Global Audiology Group in GN ReSound A-S on a non-payment basis — were mailed a revised Danish IOI-HA questionnaire. Results: Statistical analysis revealed good internal consistency along with a clear division of items into two distinct factors. Conclusions: The revised Danish translation of the IOI-HA proves internally consistent. Furthermore, it possesses psychometric properties equivalent to those reported in several corresponding studies of other translations. Data obtained from it can therefore validly be considered comparable to data obtained from previously validated translations of the IOI-HA.
