Background and Aim: Assessment of auditory processing in children is performed via special tests with confirmed sensitivity. For any adapted or developed test, there should be evidences to demonstrate acceptable test-retest reliability. Recently, two dichotic listening and two recognition of speech-in-noise tests of auditory processing have been developed in Persian language. The present study aimed to assess test-retest reliability of these tests in normal children.
MaterialsandMethods: The present observational and analytic study was performed on 40 children, aged 6-12 years old, selected from two elementary schools in Tehran. Inclusion criteria were right-handedness, normal peripheral hearing sensitivity (< 20 dB HL in frequencies of 500-4000 Hz), and normal school performance. Farsi Auditory Recognition of Digits-in-Noise (FARDIN), Persian Auditory Recognition of Words-in-Noise (PARWIN), Persian Pediatric Competing Words (PPCW), and Persian Pediatric Competing Sentences (PPCS) tests were administered in two sessions with the same conditions 45 days apart. Both relative and absolute reliability indices were calculated.
Results: The mean score of FARDIN and PARWIN did not show a significant difference between tests and retest sessions. Dichotic listening tests scores showed a significant improvement in retest session. Intra-class correlations for tests of recognition of speech-in-noise and dichotic listening tests were 0.6-0.65 and 0.6-0.9, respectively. FARDIN and PPCW showed higher absolute reliability compared with PARWIN and PPCS tests, respectively.
Conclusion:Although children' performance for dichotic tests in retest session was slightly better, it seems that auditory processing tests used in the current study have adequate test-retest reliability in normal children.
