Logical operating model of the hearing conservation program for workers

ABSTRACT Purpose: to validate the contents of an operating model of hearing conservation programs. Methods: this is a documentary and methodological research, in which the operating model was evaluated by ten experts in audiology, through the analysis of the activities developed in the implementation of the hearing conservation program. The components were analyzed according to the formula that determines the content validation index by item, and the operational logical model as a whole, according to the content validation formula by scale level. The items were considered valid when agreement among participants reached more than 80%. Results: the operating model was structured in 4 (four) dimensions, namely: (1) Management; (2) Environmental Control; (3) Attention to Hearing Health; (4) Evaluation of Efficacy and Efficiency. Each dimension corresponds to a set of activities (referred to as processes), and their respective results expected. For the structure of the program, considering its set of dimensions, material, organizational and human resources were listed. Conclusion: the proposed operating model and its components proved to be valid in their relevance and comprehensibility, offering support and applicability in evaluating the effectiveness and efficiency of the program.

摘要 研究目的：验证听力保护项目运行模型的内容效度。
研究方法：本研究为文献与方法学研究，邀请10名听力学专家，通过分析听力保护项目实施过程中开展的各项活动，对该运行模型进行评估。针对模型各组成部分，采用条目层面内容效度指数计算公式进行分析；针对整体运行逻辑模型，则采用量表层面内容效度计算公式进行分析。当专家一致性达标率超过80%时，即认为对应条目具备效度。
研究结果：该运行模型共由4个维度构成，分别为：(1) 管理模块；(2) 环境控制；(3) 听力健康照护；(4) 效能与效率评估。每个维度对应一组活动（亦称流程）及其预期达成的相应结果。结合该模型的维度框架，本研究梳理了项目实施所需的物资、组织及人力资源配置。
研究结论：本研究提出的运行模型及其各组成部分在相关性与可理解性层面均通过效度验证，可为听力保护项目的效能与效率评估提供支撑与实践应用价值。
