Summary
The Mandarin Tone Identification Test (MTIT) effectively assesses tone identification in children with hearing impairment (HI). It demonstrates strong known-groups and concurrent validity, making it a reliable tool for evaluating Mandarin-speaking children with HI.
Area of Science:
- Audiology
- Speech-Language Pathology
- Developmental Psychology
Background:
- Accurate assessment of auditory skills is crucial for children with hearing impairment (HI).
- The Mandarin Tone Identification Test (MTIT) is a novel tool designed to evaluate tone identification in this population.
- Previous research has established the reliability and sensitivity of the MTIT.
Purpose of the Study:
- To evaluate the known-groups validity of the MTIT by comparing performance across different levels of hearing loss.
- To assess the concurrent validity of the MTIT using the Mandarin Pediatric Speech Intelligibility test (MPSI).
Main Methods:
- The MTIT and MPSI were administered to 81 Mandarin-speaking children with HI (profound HI, n=41; moderate to severe HI, n=40).
- Testing was conducted in both quiet and noise conditions.
- Known-groups validity was assessed by comparing MTIT scores between the two HI severity groups.
Main Results:
- Significant differences in MTIT scores were observed between children with profound HI and those with moderate to severe HI, supporting known-groups validity.
- A strong correlation between MTIT performance and Mandarin Pediatric Speech Intelligibility test scores was found in both quiet and noise, indicating concurrent validity.
Conclusions:
- The Mandarin Tone Identification Test (MTIT) demonstrates good known-groups validity, differentiating between varying degrees of hearing impairment.
- Preliminary evidence supports the concurrent validity of the MTIT, suggesting it accurately reflects overall speech perception abilities.
- The MTIT can be confidently utilized to assess tone identification skills in children with hearing impairment.
