PURPOSE: assess satisfaction with hearing aids (HA) by applying the self-assessment questionnaire IOI-HA (International Outcome Inventory for Hearing Aids) and to correlate the characteristics of hearing loss and HA fitting process. METHOD: 98 patients from a healthy public service were assessed, of both genders, with sensorineural hearing loss, and using the HA in a systematic way for at least 3 months. The IOI-HA questionnaire was used as a guide directed structured interview with the patient. Correlated these variables with the level of user satisfaction analyzed by IOI-HA by a factor (which reflects the interaction of the patient with his HA), the second factor (related to the patient's experience with other people in their environment), and the total score for each patient. RESULTS: there was no significant correlation between these variables and user satisfaction. However, it is important to note that the averages obtained were positive and therefore the analyzes of the total sum of the IOI-HA, Factors 1 and 2, were also positive and approached the maximum score for each factor. CONCLUSION: this study found that in the studied group of HA users were satisfied with the adaptation of their HA and there were no correlations between variables and the degree of satisfaction with HA through the IOI-HA questionnaire.
