Summary
The Craig Lipreading Inventory shows high reliability and validity for evaluating lipreading skills in children aged 3-8. This study provides crucial normative data for accurate assessment.
Area of Science:
- Audiology
- Speech and Language Pathology
- Developmental Psychology
Background:
- The Craig Lipreading Inventory (CLI) is used for assessing lipreading abilities in children.
- Previous evaluations lacked rigorous statistical analysis and normative data.
- This necessitates establishing the psychometric properties and age-specific standards for the CLI.
Purpose of the Study:
- To evaluate the internal validity and test-retest reliability of the CLI.
- To collect normative data for children aged 3 to 8 years.
- To establish age-specific scoring standards for the CLI.
Main Methods:
- Administered the CLI to 150 children aged 3 to 8 years.
- Analyzed internal consistency for each subtest.
- Examined correlations among subtests and score differences across age groups.
Main Results:
- Demonstrated very high internal consistency for all CLI subtests.
- Found significant correlations between subtests, supporting construct validity.
- Identified significant score variations across the three age cohorts, confirming the need for age-specific norms.
Conclusions:
- The Craig Lipreading Inventory is a valuable and reliable tool for assessing lipreading skills in children.
- The study provides preliminary Z-scores and percentile ranks for each age group.
- Established normative data and validated psychometric properties support the CLI's clinical utility.
