There were 30 ISAD users older than 18 years of age participating in the study (mean: 66.36 years); 19 men (63%); 11 women (37%).ResultsThe participants reported greater satisfaction (mean) for questions: 1 (6.35); 3 (6.85); 5 (6.10); 6 (6.80); 8 (6.33); 9 (6.80); 11 (6.16); 12 (6.93) and 15 (6.52). Less satisfaction: question 4 (3.16); 7 (3.41) and 13 (2.83). The comparison of each question with the first and second application of the questionnaire did not present statistically significant results, thus yielding good reproducibility.
