Evaluation of the localization auditory screening test in children 6-18 months of age
Insights
This study developed an automated auditory screening test for infants aged six to 18 months. The test effectively identifies infants with potential hearing issues, suitable for public health programs.
Area of Science:
- Pediatric Audiology
- Public Health Interventions
- Infant Development
Background:
- Early identification of hearing loss in infants is crucial for development.
- Existing auditory screening methods may require refinement for large-scale application.
- Developmental and child health programs necessitate efficient screening tools.
Purpose of the Study:
- To develop and evaluate an automated auditory screening test for infants aged 6–18 months.
- To assess the test's efficacy in identifying infants with potential hearing impairments.
- To determine the feasibility of integrating this screening tool into public health settings.
Main Methods:
- Development of specialized equipment and testing protocols over two years.
- Auditory screening of 250 infants within a county health department child development clinic.
- Evaluation of screening results via physical/developmental examinations and historical case reviews.
Main Results:
- The automated procedure successfully differentiated infants with normal hearing from those with potential hearing problems.
- The screening test demonstrated a high degree of effectiveness in the target age group.
- The methodology proved adaptable for use in public health programs.
Conclusions:
- The developed automated auditory screening test is effective for infants aged 6–18 months.
- The procedure can be successfully integrated into existing public health initiatives like child development clinics.
- This tool aids in the early detection of hearing deficits in infants, supporting timely intervention.
Abstract:
The present paper is a report of a project to develop an automated auditory screening test for infants six to 18 months of age. The first year of the project was devoted to developing equipment and test procedures; the second year was concerned with testing the effectiveness of the equipment and procedures on an actual population of six to 18 month old infants. Two-hundred and fifty infants were screened auditorily as part of a county health department child development clinic. The pass/fail results of the screening test were evaluated in terms of physical and developmental examination following the screening and by means of a case review of the child's previous history. The results indicate that the procedure under investigation can be used to differentiate the normal hearing infant from the infant with possible hearing problems. It is shown by the test environment in which this study was conducted that the procedure reported can be successfully incorporated into a public health program, i.e., child development clinics or EPSDT programs.
