Comments: This study is included on ICPSR's Periodic Release CD-ROM 96005. The Periodic Release CD-ROM is a product designed for use on a Windows- or DOS-based personal computer and is intended for use as a means of data distribution. It may also be used within the Macintosh environment utilizing either system 7.0 and above or system 6.08 and the appropriate PC emulation software. The CD-ROM does not contain software for text or data searches, extraction or analyses.

The files with the .EXE extension are self-extracting files that were generated using Info-ZIP's ZIP compressor/archiver and PKWARE's ZIP2EXE utility for generating self-extracting files. Self extracting files allow PC users to easily and quickly decompress and transfer the files to their equipment, usually a hard disk, without the need to install any extraction software locally.

Users should consult the study files listing (S0000LST.TXT) of the appropriate study to determine the storage requirements for the uncompressed files.

Abstract: The purpose of this survey and follow-up case-control study was to assess the prevalence of minimal hearing loss in third-, sixth-, ninth-, and twelfth-grade children and to determine whether children with minimal hearing loss experienced any psychoeducational or functional complications. Children were evaluated for hearing threshold levels and type of hearing loss, middle ear function and associated abnormalities, acoustic otoscope results, diagnostic immittance, and GSI-37 auto tymp results. Case-control assessments included comprehensive tests of basic skills scores (reading-vocabulary and comprehension, language-mechanics and expression, math, spelling, and science), and behavior problems reported by the teacher. Other variables covered age and grade in school. Parts 1-12 contain survey data which are consolidated, together with additional recodes, in Parts 13 and 14. Parts 15 and 16 contain the case-control data.
