Reliability of the TIP and DIP speech-hearing tests for children

Area of Science:

• Pediatric Audiology
• Speech-Language Pathology
• Hearing Science

Background:

• Adult speech test reliability is established, but data for children are limited.
• Speech Recognition Threshold (SRT) and speech intelligibility tests are crucial for diagnosing hearing impairments.

Purpose of the Study:

• To evaluate the test-retest reliability of the Tone Identification (TIP) and Discrimination (DIP) tests in children.
• To compare pediatric speech test reliability with existing adult data.

Main Methods:

• Administered TIP and DIP tests to 295 normal-hearing and 138 hypacusic children (ages 3-12).
• Retested subjects within one week to assess reliability.
• Calculated test-retest reliability coefficients and standard errors of estimate.

Main Results:

• TIP test showed good reliability (0.72 for normals, 0.89-0.99 for hypacusics).
• DIP test demonstrated moderate to good reliability (0.46-0.51 for normals, 0.60-0.93 for hypacusics).
• Standard errors were approximately 3 dB for TIP and 10% for DIP, similar to adult values.

Conclusions:

• The TIP and DIP tests exhibit reliable performance in children across different age groups and hearing statuses.
• Findings support the use of these speech tests for pediatric audiological evaluations.
• Pediatric speech test reliability is comparable to that observed in adults.
