Abstract:   (493 Views)
Objectives: Since there is no reliable and valid tool in order to assess all the features of the phonological skills of children whose first language is Azeri, Speech-Language Pathologists usually use informal or Persian instruments. So, it is important to develop a tool in Azeri language for assessing of articulation and phonological skills. For this reason, this study aimed to develop an Azeri Phonological Test (APT), and to assess the validity and reliability of this test for children from 4 to 6 years old whose first language is Azeri.
Methods: Participants were 77 typically developing children from 4 to 6 years old (41 boys and 36 girls). The method used for sampling in the present study was cluster sampling. Firstly, Tabriz city was geographically separated into three sections, namely south, north, and, center, and then the kindergartens of each area were randomly selected for sampling. Participants were divided into 2 groups: 48–60 months (n=38) and 61–72 months (n=39). In order to assess the phonological skills, nine stories were designed. An expert panel which were fifteen speech-language pathologists investigated the content validity of the stories. Then the psychometric characteristics of the Azeri Phonological Test including reliability (test-retest reliability, inter-rater, and internal consistency) and validity (construct –known group validity) were assessed. The used statistical tests were Intra-class Correlation Coefficient (intra-rater reliability and test-retest), Kuder-Richardson 21 (internal consistency) and the independent-samples t-test (known-groups validity).
Results: The content validity of the whole test was 0.91. Construct validity evaluation showed that age affects the test scores but not gender. There was a significant correlation between the results of test–retest and inter-rater reliability and also, the test had a high internal consistency.
Discussion: Based on the findings, Azeri Phonological Test (APT) is a reliable and valid test for the assessment of the abilities of 4-6-year-old children in terms of the production of sounds in the context of re-telling stories
