Test-Retest Reliability of Virtual Acoustic Space Identification Test in School-Going Children

Area of Science:

• Audiology
• Neuroscience
• Developmental Psychology

Background:

• Spatial hearing acuity is crucial for auditory processing and development.
• The virtual acoustic space identification (VASI) test offers a novel method for assessing spatial hearing.
• Evaluating the VASI test's reliability in children is essential for its clinical application.

Purpose of the Study:

• To assess the test-retest reliability of the VASI test in typically developing school-aged children.
• To determine if VASI scores are consistent across multiple measurement sessions.
• To establish the VASI test's utility for evaluating spatial-hearing acuity in pediatric populations.

Main Methods:

• The VASI test was administered to 40 children (aged 7-13 years) across three sessions (baseline, intrasession, intersession).
• Participants completed assessments of virtual sound location perception under headphones.
• Accuracy scores were analyzed using intraclass correlation coefficient and Bland-Altman analysis.

Main Results:

• The VASI test exhibited excellent test-retest reliability for overall accuracy scores.
• Moderate-to-high reliability was found for location-specific accuracy scores.
• Low response variability and minimal bias were observed across measurement sessions.

Conclusions:

• The VASI test is a reliable tool for assessing spatial-hearing acuity in school-aged children.
• High test-retest reliability and portability support its use in classroom settings.
• The VASI test can aid in the early diagnosis and intervention of spatial deficits, impacting academic success.
