Propriedades psicométricas do questionário internacional: aparelho de amplificação sonora individual

Abstract

Summary It is paramount to assess the psychometric properties of self-assessment tools in order to check the tests' reliability and validity, also to enable proper outcome interpretation. Aim to check the psychometric properties of the IOI-HA (International Outcome Inventory for Hearing Aids) in its Portuguese version, called QI-AASI (International Questionnaire - Individual Sound Amplification Device), in terms of internal uniformity, correlation between the items and reproducibility. Study design: descriptive, observational and cross-sectional. Materials and Methods the questionnaire was deployed to 53 hearing aid users, 34 females and 19 males, with ages between 19 and 92 years - from incomplete basic education to complete higher education, encompassing subjects with monoaural and binaural sound amplification. Results the QI-AASI had a Cronbach Alpha of 0.69. In the correlation among the items, there were numerous significant correlations. The instrument was properly reproducible, except for item # 6, which presented a significant difference in comparing test and the retest. Conclusions the QI-AASI is suggested in the rehabilitation process of users of hearing aides; nonetheless, the questionnaire can be difficult for subjects with low social and economic status when self-employed.

“…Moreover, it is possible to verify through analyzes that there was no difference of answer among questions (p=1.191). In a study also developed in the south region of the country, in 2010, the mean values verified through the seven questions varied in 3.42 to 4.67 points, these results are very similar to this study 18 . A different study developed in the north region of the country, also found mean values similar to scores which varied in 3.7 to 4.4 points.…”

Self-reported outcomes after hearing aid fitting in Minas Gerais, Brazil

“…IOI-HA has been translated into different languages and facilitates comparisons between different investigations and clinical service models. In assessing the psychometric properties of the IOI-HA translated into Portuguese, the questionnaire showed moderate internal consistency of 0.69, measured by Cronbach's α coefficient, and reliability in 6 questions (12) . The value of Cronbach's αfor the questionnaire in English was 0.78 (10) .…”

“…The questionnaire was translated for different countries. However, this questionnaire, in Brazil, was considered difficult to understand for people with low social-cultural level (11) , who may not be able to answer it without the help of a professional service. This situation can lead to responses induced by the researcher (12) .…”
