Measuring Satisfaction with Amplification in Daily Life: The SADL Scale

Abstract

The SADL scale is both brief enough to be clinically acceptable and comprehensive enough to provide a valid assessment of an inherently multidimensional variable. Additional assessment is necessary to refine understanding of its test-retest properties, explore validity issues, and determine clinical, research, and administrative applications of the data.

“…Regarding validity of questionnaire, upon comparing satisfaction with hearing aids in daily life between NorthAmerican standard (Cox and Alexander, 1999) and the present study, we detected similar results, with slightly better response among Brazilian subjects. Percentiles 20 and 80 were equivalent with small difference in subscale of negative factors.…”

“…Results of overall score and subscales were equivalent to those of the original study (Cox and Alexander, 1999), reaching the same configuration in percentiles and in scales of higher or lower satisfaction levels.…”

“…The patients that acquired the hearing aids at that time but did not effectively use them (24 patients, which amounted to 7.6% of the total), did not join the study because the variable of interest that is part of the satisfaction rate depends on the point of view of the patient about systematic use of amplification (Cox and Alexander, 1999; Hosford-Dunn and Halpern, 2000) ( Figure 1). We excluded from the study subjects who were aged less than 18 years, who had acquired hearing aids within less than 6 weeks, because satisfaction should be measured only after one month post-fitting to ensure reliability of results (Humes, 2002-a); people with severe limitation of understanding and expressing to respond the questionnaire, and those that did not agree to participate.…”

“…The satisfaction rate with use of hearing aids in daily life was conducted using the questionnaire Satisfaction With Amplification in Daily Life -SADL, developed by Cox and Alexander (1999), with a sample of 257 subjects, mean age of 72 years, originated from an American medical center of the veterans, a community center for speech and hearing and a private clinic of hearing. SADL was validated by the authors in 2001.…”

“…Satisfaction is the measurement of auditory rehabilitation outcome that represents the most comprehensive combination of factors required to define final outcomes, given that the variable of interest represents the point of view of the patient and it is not related only with performance of hearing aid (Cox and Alexander, 1999), depending exclusively on people's perceptions and attitudes (Hosford-Dunn and Halpern, 2000).…”
