Design, building and validation of an instrument to assess occupational dysphonia risk
Objective: to design and validate an instrument that enables self-reported risk assessment
for occupational dysphonia.
Method: transversal design, exploratory type of evaluative nature. Four phases were developed (1) consolidation of the conceptual framework of occupational dysphonia risk; (2) design of the instrument; (3) judge evaluation - content validity; and, (4) application of the instrument, reliability.
Results: The Assessment Instrument for Risk of Occupational Dysphonia - AIROD is composed of 25 items, distributed into 5 categories established by Risk Factors assessed on a Likert scale. The statistical test yielded a modified Lawshe’s index of 0.853 and a Cronbach’s Alpha of 0.809. A review of the literature is provided to support the conceptualization of risk factors related to occupational dysphonia.
Conclusions: AIROD becomes an objective tool designed and validated to measure the risk of occupational dysphonia. It enables a self-reported identification of the risks a person who uses his or her voice as a work tool may be exposed to.
