Research Problem and Specific QuestionsVoice problems are prevalent, especially among women and those in voice-intensive occupations like teaching and call center work. These issues lead to extended sick leave, impacting personal finances, psychosocial well-being, and productivity. The project aims to promote sustainable work ability and voice health by:Identifying individuals at risk of developing work-related voice disorder.Increasing accessibility to preventive voice training.Developing a feasible methodology and process for risk assessment and voice health surveillance.A workplace context where the need is particularly calling is the school/preschool context, since occupational voice problems in teachers are common and also risk affecting children’s education.Data and MethodThe project will conduct three studies:A cross-sectional mixed-method study to identify individuals with work-related voice problems using a Swedish version of the instrument The Work Hoarse.A randomized controlled intervention study to assess the effectiveness of minimally supervised voice training delivered via a digital app or written instructions.A consecutive focus-group study to develop and explore the feasibility of a model for risk assessment and occupational voice health surveillance through stakeholder workshops.Societal Relevance and UtilisationVoice problems in professions reliant on vocal communication lead to significant costs for individuals, employers, and society. By addressing these issues, the project aims to reduce sick leave, improve productivity, and enhance overall public health. The findings will benefit occupational health services and employers by providing tools for better voice health management.Plan for Project RealisationThe project will run over three years, with the first 6 months devoted to preparations (e.g., ethical approval). The three studies will be conducted consecutively, although with some overlap, especially between Study 2 and Study 3. The research group consists of experts in speech-language pathology, voice ergonomics, and occupational health, and a speech-language pathologist specializing in voice as a PhD student. Collaboration with key stakeholders – employers, occupational health services and safety representatives at teachers’ unions – has been initiated. Apart from scientific dissemination at conferences and in journals, results will also be presented in non-academic stakeholder forums, and as guidelines for occupational health.
