Translation of the international outcome inventory for hearing aids into Portuguese from Portugal.

Objective: To translate the International Outcome Inventory for Hearing Aids (IOI-HA) Questionnaire from English to Portuguese (from Portugal) and to validate this instrument of study on the Portuguese population.

Design: In this prospective study, a translation from English into Portuguese of the IOI-HA was performed, and linguistic adaptation and counter translation were also accomplished. The data were analysed for internal consistency testing for correlations between each individual item and the total score of the IOI-HA, assessing the Cronbach α and performing test-retest analysis.

Validity and Reliability of the Hearing Handicap Inventory for Elderly: Version Adapted for Use on the Portuguese Population.

Background: The use of the Hearing Handicap Inventory for the Elderly (HHIE) questionnaire enables us to measure self-perceived psychosocial handicaps of hearing impairment in the elderly as a supplement to pure-tone audiometry. This screening instrument is widely used and it has been going through adaptations and validations for many languages; all of these versions have kept the validity and reliability of the original version.

Purpose: To validate the HHIE questionnaire, translated into Portuguese of Portugal, on the Portuguese population.
