ioiha_c.gif  International Outcome Inventory for Hearing Aids (IOI-HA)




The IOI-HA covers a minimal set of seven core outcome items which are sufficiently general to apply to many different types of investigations carried out in different countries in the world. The items are practically oriented and comprise a mini-profile more than a scale. It was developed at an international workshop on "Measuring Outcomes in Audiological Rehabilitation Using Hearing Aids" in Eriksholm in Denmark. The IOI-HA was not intended to replace existing outcome measures but to serve as a useful addendum to existing measures in a research context. It might potentially function as a stand alone tool for quality assessment.

Tips: For scoring purposes, responses from left to right on the page are assigned a value from 1 to 5. The values are then added. Higher scores indicate a more favorable outcome.
