EFFECTIVENESS OF COMPUTER-BASED HEARING TEST & TRAINING

噪声性听力损失(NIHL)是人类最常见的职业病 美国(NIOSH，1996a)，是一种不可逆转的听力障碍，导致 巨大的金钱和个人成本。持续使用听力保护器 设备(HPD)减少了噪声暴露和后续的NIHL。不幸的是， 工人们并没有始终如一地佩戴HPD。注意力需要被引导到 找出最有效的方法来帮助工人采用 使用HPD。 该项目的目的是防止操作工程师(OE)中的NIHL， 操作重型设备的建筑工人，通过测试其有效性 一种创新的量身定做的干预措施，以增加他们对HPD的使用。四 这项研究的具体目标是：(1)设计和测试 一种创新的干预措施对OES增加其使用的有效性 HPD；(2)确定OES听力损失的患病率；(3)证明 提供计算机自主管理测听的可行性 建筑中的筛查测试(SAAST)和听力保护干预 工人培训中心；和(4)测试和细化使用的预测因子 听力保护模型(PUHPM)，一个因果模型，旨在解释使用 OES的头盔显示器。 为了实现这些目标，这项拟议的项目将分三个阶段进行 阶段，(I)干预研究前的发展，(Ii)干预研究， (3)干预措施的研究后评价。在第一阶段，定性数据 将获得OES对使用HPD的看法、意见和态度 通过焦点小组指导制定和细化干预措施。 这一干预措施和SAAST将进行试点测试，并根据需要进行修订。 第二阶段将测试个人定制、交互、 多媒体干预与SAAST相结合，通过计算机和 将其与对照干预进行对比。第三阶段将获得工人的 对SAAST的反馈和指导修订的实验干预 该节目正在为全国发行做准备。 这项拟议的研究将以一种创新的形式提供干预， 基于最近关于以下方面的研究结果： 个别定制的干预措施。此外，这一拟议项目将 评估培训中心提供基于计算机的SAAST的可行性。 拟议项目的结果将为未来的干预提供一个模型 在职业安全和健康领域进行研究并帮助减少严重的 可预防的损害，NIHL。

Noise-induced hearing loss (NIHL), the most common occupational disease in the U. S. (NIOSH, 1996a), is an irreversible hearing impairment, causing significant monetary and personal costs. Consistent use of hearing protective devices (HPDs) reduces noise exposure and subsequent NIHL. Unfortunately, workers are not consistently wearing HPDs. Attention needs to be directed toward identifying the most effective ways to assist workers in adopting the use of HPDs. The purpose of this project is to prevent NIHL in operating engineers (OEs), construction workers who operate heavy equipment, by testing the effectiveness of an innovative tailored intervention to increase their use of HPDs. Four specific aims will be addressed in this study: (1) design and test the effectiveness of an innovative intervention for OEs to increase their use of HPDs; (2) determine prevalence of hearing loss in OEs; (3) demonstrate the feasibility of providing computer-based self-administrated audiometric screening tests (SAAST) and hearing protection interventions at a construction worker training center; and (4) test and refine the Predictors of Use of Hearing Protection Model (PUHPM), a causal model designed to explain use of HPDs by OEs. To achieve these aims, this proposed project will be conducted in three phases, (I) pre-study development of intervention, (II) intervention study, and (III) post-study evaluation of intervention. In Phase I, qualitative data on OEs' perceptions, opinions, and attitudes on use of HPDs will be obtained through focus groups to guide development and refinement of an intervention. This intervention and the SAAST will be pilot tested and revised as needed. Phase II will test the effectiveness of an individually tailored, interactive, multimedia intervention combined with the SAAST and delivered by computer and contrast it with a control intervention. Phase III will obtain workers' feedback on the SAAST and the experimental intervention to guide revisions in the program in preparation for national distribution. This proposed study will deliver the intervention in an innovative format, building on recent research findings regarding the effectiveness of individually tailored interventions. Further, this proposed project will assess the feasibility of providing computer-based SAAST at a training center. Results from the proposed project will provide a model for future intervention research in occupational safety and health area and aid in reducing a serious preventable impairment, NIHL.
