Abstract :
Background: One of the common problems of those who refer to audiology
clinics, is difficulty of hearing in noisy conditions. Different tests have been
developed for diagnosis and quantification of reduced ability of speech perception
in noise and the Quick Speech-in-Noise test is one of the most appropriate of
them. The goal of the present study was to develop and validate the Persian
version of the Quick Speech-in-Noise Test in normal, Persian speaking, 18-25
year-old participants.
Methods: This study had two main stages: first, developing the test materials and
determining the content validity and the second, determining the equivalency
of the test material lists, and assessing the reliability of them.
In the first stage, sentences having content validity were developed and recorded.
In the second stage,in order to determine list equivalency, the lists were presented
to 60 Persian-speaking (gender balanced), 18-25 year-old students and the
average SNR-50 for each list was calculated using the Spearman-Kärber formula.
In order to determine the reliability of the test, the test was again administered
to15of the primary participants, two weeks later.
Results: among80 sentences developed, 60 received enough credits from
audiologists and speech therapists. Average SNR-50 in the Persian language was
calculated as -0.25 dB. Thirty six content valid sentences, according to special
criteria, were divided into six lists each containing 6sentences. The SNR-50 for
each list revealed that lists number 2,3, 4and 5 were equivalent. Examination of
test-retest reliability indicated that lists number 1,2,3,4 and 6 were reliable (P<0.05).
Conclusion: Present study was developing three equivalent and reliable lists
(number 2,3,4) for the Persian version of the Q-SIN test which are useful for
diagnosing and selecting the best rehabilitation method for people with reduced
speech perception in noise
