Resumen
This study had the objective to analyze some of the
aspects involved in the process of
selecting and fitting hearing aids, order to verify
the possible influence on the expectations of
elderly patients as to the results with the use of
amplification, as well as the relationship of
these expectations with the success of auditory reh
abilitation. Were considered as criteria for
inclusion in the sample: elderly individuals, patie
nts with bilateral sensorineural hearing loss,
symmetric, mild to moderately severe degree, with i
ndication of using hearing aids bilaterally,
without previous experience as a user of it and abs
ence of any cognitive impairment. The
sample was constituted of 16 subjects, aged between
64 and 94 years old. The evaluation
was performed at two different times: 15 days befor
e and 15 days after the fitting of hearing
aids. Subjects responded, firstly, to an anamnesis,
which provided information regarding age,
occupation and educational level of subjects studie
d, beyond the motivation for the use of
hearing aids and presence or absence of a companion
. For analysis of the expectations, was
applied the Questionnaire for expectations evaluat
ion of the adult / elderly, new user of the
hearing aids , followed by the Hearing Handicap Inv
entory for the Elderly - Screening Version
HHIE/S, to measure the individual's participation
constraint with and without the use of
hearing aids. The overall benefit with the use of h
earing aids was evaluated using the
International Outcome Inventory for Hearing Aids
IOI-HA. The communicative performance
was evaluated by determining the Percentage Index S
entence Recognition in Quiet (PISRQ),
using the Portuguese Sentences Lists test PSL, wi
th and without the use of hearing aids.
The data were analyzed using parametric tests and n
onparametric, with p≤0,05. Were obtained positive expectations about the results wi
th the use of hearing aids to all individuals
in the sample. The restriction of participation was
classified as moderate for 14 individuals
(87.5%) and below this level for the remaining indi
viduals (12.5%). The average of overall
benefit obtained was 84%, showing a correlation sta
tistically significant and negative, with
the results of the assessment expectations. The sub
jective evaluation of the benefit, by
comparing the results of HHIE/S pre and post-adapta
tion, showed satisfactory results for the
entire sample. The same was not observed in the obj
ective assessment, comparing the
PISRQs under the same conditions. It was concluded
that: the expectation about the results
with the use of hearing aids has been positive for
the entire sample, independent of other
variables considered. Also, the more positive expec
tations presented, smaller were the
chances of the individual to report the overall ben
efit with the use of hearing aids.
Nevertheless, there was some benefit in this regard
. Objectively, the benefit was not
observed in all individuals evaluated considering t
he speech tests, however, subjectively, it
was observed throughout the sample. Thus, the expec
tations were not influenced by aspects
of the process of selection and fitting of hearing
aids. Already the influence of expectations
on the success of the process occurred only in rela
tion to the overall benefit evaluated.
