چکیده: (2044 مشاهده)
Objectives: The present study aimed to develop and validate a quick repetition test using familiar and culture-based words for assessing Persian-speaking children with Speech Sound Disorders (SSDs).
Methods: The study sample was divided into two groups, including 419 participants without any clinical signs of speech impairment and 36 cases with SSD. The psychometric properties of the single word quick repetition test, including reliability (inter-rater and test-retest reliability) and validity (construct, discriminant, convergent, clinical and concurrent validity) were examined. Moreover, the descriptive data for children without SSD were reported.
Results: The obtained test-retest and inter-rater reliability data were satisfactory with Intraclass correlation coefficient (ICC): >0.7. There was a positive correlation between the results of the quick repetition test and phonetic test, indicating the scale’s acceptable convergence validity. Using inflated beta-binomial regression, statistically significant improvement in test score was found with age (discriminant validity). Comparing the correct responses of the control and case groups (clinical validity) revealed a significant difference in responses between the study groups. Results of Bland–Altman plot suggested an acceptable agreement between quick repetition test and phonetic test (construct validity).
Discussion: The Persian quick repetition test is a valid and reliable instrument facilitating the screening of speech sound abilities in 3-8-year-olds. Moreover, this test’s conciseness makes it easily applicable in clinical practice and epidemiologic investigations. Establishing descriptive data from a large sample facilitated comparing children’s speech ability to the speech development standards.
