Auditory disablements: an update.
In 1999, the World Health Organization issued a document (Beta-2 ICIDH-2) that outlines proposed revisions to the original International Classification of Impairments, Disabilities, and Handicaps. The document, issued for trial purposes, is significant in that it redefines the theoretical context in which audiological research into hearing disability has operated since 1980 and will develop in the future. The purpose of this article is threefold. First, it provides an introductory descriptive overview of the primary disablement dimensions outlined in the Beta-2 version of the ICIDH-2 framework. Second, in discussing the implications of the revised framework for audiology, the article highlights particular classification issues that require clarification if the framework is to be applied effectively in audiological research and practice. Third, the article evaluates the revised framework in the context of recent conceptual developments in audiological research and raises a number of issues for further discussion and investigation. The article concludes that the Beta-2 ICIDH-2 represents a significant advance on the original ICIDH classification framework on three counts. First, much of the rationale underpinning the revised framework, particularly its redefinition of the primary disablement dimensions, is consistent with recent conceptual developments in audiological research into hearing disablements. Second, the framework offers specific pointers for the development of current audiological research and practice. One potential line of enquiry focuses attention on specific ICIDH-2 dimensions that are currently under-represented in audiological literature, namely, the participation and contextual factors dimensions. Another potential line of enquiry focuses attention on issues pertaining to the measurement of function, specifically the inclusion of "positive" outcome indicators in assessment. Finally, the publication of the revised ICIDH-2 framework offers a standard frame of reference from which to conduct larger debates in the audiological literature about the nature and purpose of audiological rehabilitation and the influence of the ecological perspective on the rehabilitative process.
