[Test Diagnosis of Processing Disorders (APD) in Primary School - a factor analytical study].

Objective: Our eclectic test battery for diagnosing Auditory Processing Disorders (APD) was applied in some pre-studies. Now, its underlying content structure should be examined by a factor analytic study.

Material And Methods: Test results from 143 children with APD with an average age of 8.

[Development of Auditory Processing and Perception Skills with and without APD in Primary School Age].

Background: We examined two student age groups (1 and 4 class) in a control-group comparison whether the maturation processes of the central hearing system in typically developing children are also present in children with Central Auditory Processing Disorders (CAPD) at primary-school age.

Materials And Methods: The analyses included results of a behavioral test battery from 82 first graders (40 with CAPD; 42 healthy controls) and 65 fourth graders (35 with CAPD; 30 healthy controls). An ANOVA with the total value of the following 7 standardized examinations, and subsequently a MANOVA with the detailed test results were carried out: Speech (words) in Noise Recognition (Göttinger Sprachaudiometrie II); Dichotic Word Pair Understanding (Uttenweiler-Test); Heidelberger Phoneme Discrimination Subtests: Phoneme Discrimination, Phoneme Identification, Phoneme Analysis; the Subtest Auditory Sequential Memory for Digits of the Illinois Test of Psycholinguistic Abilities (German version); Mottier's Nonword Repetition Test.

Despite normal hearing thresholds in pure-tone audiometry, 0.5-1% of children have difficulty understanding what they hear. An auditory processing disorder (APD) can be assumed, which should be clarified and treated.

As a prerequisite for diagnosing auditory processing disorders (APD), differential diagnostic considerations are essential, especially with regard to language comprehension disorders, attention deficit hyperactivity disorder, specific cognitive impairments (e. g., in memory or multi-modal perception performance), specific learning disorders affecting reading and/or spelling, and autistic-type diseases.

[Guideline: Auditory Processing and Perception Disorders: Diagnostics : S1-Guideline of The German Society of Phoniatrics and Pediatric Audiology].

In accordance with international consensus papers, auditory processing disorders (APD) are defined as disorders of central processes of hearing. Following the establishment of a commission of experts from the German Society for Phoniatrics and Pediatric Audiology, the existing S1 guideline was revised and updated. In this chapter, a position is taken on the clinical diagnostics of APD as well as on the delimitation of similar disorders.
