PURPOSE: To analyze the hearing aid satisfaction after one, three and six months of use. METHODS: Longitudinal study with 22 elderly individuals who participated in a selection and adaptation process for sound amplification devices in a high complexity health service. The study was carried out at the institution on the day of hearing aid fitting and on the follow-up appointments after one, three and six months of fitting. The data is part of the application of the Satisfaction with Amplification in Daily Life (SADL) questionnaire. In order to assess the consistency of the items composing the positive effects category of the SADL survey after one, three and six months of hearing aid use, the Cronbach's coefficient alpha was used. RESULTS: There were improvements to the SADL scores in the period between the first use of the hearing aid and the following six months. Cronbach's coefficient alpha was calculated excluding questions 9 and 10, simultaneously. The coefficient values were 0.75 after a month, 0.69 after three months, and 0.81 after six months. Questions 9 (Do you feel more confident when you use hearing aids?) and 10 (The sounds that you hear with your hearing aids are normal?) created inconsistency in the assessment after one and three months of amplification use. CONCLUSION: The results obtained with the SADL indicate a high level of satisfaction. The averages for positive effects, negative effects, and global score were different after one, three and six months of hearing aid use.
