[Content validity of Tavana: a test for evaluation of auditory skills of 3-4 year-old hearing-impaired Persian children]

ABSTRACT

Evaluation of hearing-impaired children's auditory skills by a valid test is very important before starting auditory training. There are many different tests available for languages other than Persian, and some limited Persian tests for children above 5 year of age as well. Accordingly considering the importance of early intervention, we aimed to design a test for evaluating auditory skill of 3-4 year-old hearing-impaired Persian [Farsi] children, which is not available to date. The study method was test [scale] construction. The test named Tavana includes four subtests detection, discrimination, identification and sentence comprehension. For determining content validity of the test, the vocabulary of 3-4 year-old normal-hearing and hearing-impaired children and also the comments of seven specialists were applied. We classified 10, 10, 8 and 6 sub skills for 1[st] to 4[th] subtests, respectively. The content validity of Tavana test's subskills were 100%, 83%, 96% and 95%, respectively [mean=94%]. Mean time for test performance was 82 minutes. Content validity of Tavana test was 94% which was statistically valid compared to Modarres test [97%] and Mazaheryazdi test [88%]
