[Auditory Processing Disorder: Is The Diagnosis Already Possible In First Graders?]

Area of Science:

• Audiology
• Developmental Psychology
• Pediatric Medicine

Background:

• Auditory Processing Disorders (APD) significantly affect academic performance in school-aged children.
• Previous studies identified performance differences in older primary school students (2nd-4th grade) with APD.
• The diagnostic utility of auditory tests for first graders with APD remained underexplored.

Purpose of the Study:

• To investigate auditory processing abilities in first-grade children.
• To determine if first graders with APD exhibit performance deficits comparable to older students.
• To assess the effectiveness of current auditory tests for diagnosing APD in early elementary school.

Main Methods:

• A behavioral test battery comprising 14 auditory tests was administered.
• Participants included 41 first graders diagnosed with APD and 37 typically developing controls (aged 6-8 years).
• Performance metrics were statistically compared between the APD and control groups.

Main Results:

• Significant group differences were observed in 12 out of 14 auditory tests.
• Children with APD consistently scored lower than controls, except on tests of sound frequencies and intensities.
• Monaural threshold values approached statistical significance after Bonferroni correction.

Conclusions:

• First graders with APD can be reliably distinguished from their typically developing peers using auditory tests.
• A trend of reduced auditory performance in first graders with APD mirrors findings in older children.
• The clinical applicability of nonverbal auditory tests for diagnosing APD in this young age group warrants further consideration.
