the reliability and equivalency of the persian version of quick speech-in-noise test in 7-12-year-old

Background and aim: in a noisy environment, children struggle more than adults to understand speech. various tests at different levels of cognition are available to evaluate children’s speech perception abilities in a noisy environment. the present study aimed at determining the reliability and equivalency of the persian version of the quick speech-in-noise (p-q-sin) test in 7-12 years old school-aged children. methods: a total of 120 (60 girls) students with normal hearing were chosen from primary schools in district 2 of kerman city, iran. they were in five age groups ranging from 7 to 12 years (24 children per age group). pure tone audiometry test was performed on the samples, then nine lists of p-q-sin of previous studies (khalili et al. and shayanmehr et al.) were administered on these participants. to obtain the test-retest reliability, three weeks later, the re-test was performed. results: in the test-retest reliability, lists 1 and 4 of khalili et al. and list 2 of shayanmehr et al. were highly correlated (p<0.05). there were no significant differences between the scores of girls and boys (p>0.05). the participant’s performance improves as the age increases. conclusion: none of the lists of shayanmehr et al. was reliable and equivalent. list 1 and 4 of khalili et al. were reliable and equivalent; therefore, they can be used in clinical application for children in the age range of 7 to 12 years by considering the norm of signal-to-noise ratio loss.
