Abstract
A questionnaire of handicap was developed to assess the psychosocial disadvantages attributable to noise-induced hearing loss (temporary or permanent). Sixty-five workers in a metal product plant completed the questionnaire with their nearest relative. A principal-component analysis was applied to the answers. Results show that the disadvantages can be grouped under three dimensions, that is, (1) quality of life at home and at work; (2) isolation and self-esteem, and (3) telephone use and leisure activities. Variables that could influence the disadvantages were tested by multiple-regression analyses. Results indicate that the variable most predictive of the disadvantages is self-acknowledgement of having a moderate or severe hearing problem. These findings are discussed in terms of perspectives for rehabilitation.
