Study summary

This study aims to determine the prevalence of hyperacusis and misophonia among teachers and to explore how these auditory sensitivities may relate to occupational stress. By examining teachers' sensory challenges in school environments, the study seeks to contribute to a better understanding of their impact on professional well-being and to inform strategies that can improve working conditions.

Read the detailed description

Misophonia is characterized by reduced tolerance to specific everyday sounds, such as chewing, breathing, or tapping, and may also be triggered by environmental noises from engines, animals, or mechanical sources. Hyperacusis, similarly, involves an increased sensitivity to ordinary sounds and discomfort in response to noises that are typically well tolerated by individuals with normal hearing.

Teachers represent a population potentially at higher risk for these conditions due to daily exposure to varying classroom sounds and occupational noise. Understanding how common these auditory sensitivities may be in this group will help clarify their potential impact on teachers' well-being and occupational functioning. Therefore this study will investigate the prevalence of misophonia and hyperacusis among actively working teachers.

The study will include teachers aged 22-45 without diagnosed hearing loss, chronic illness, or psychological disorders. Participants will complete a sociodemographic form assessing health and work-related characteristics, followed by validated measures: the Khalfa Hyperacusis Scale for hyperacusis and the AMISOS-R for misophonia. Data obtained from these assessments are expected to contribute to a clearer understanding of sensory challenges in educational environments and support future strategies to improve teachers' occupational health.

Study population

The study population will consist of teachers actively working in preschool, elementary, middle, and high schools. Participants will be aged 22 to 45 years, without diagnosed hearing loss, chronic illnesses, or psychological/psychiatric disorders. The study will include teachers from various schools to represent a diverse range of educational environments and experiences. Both male and female teachers will be eligible, and participants must be willing to provide informed consent prior to participation.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Prevalence of Misophonia Among Teachers

    The proportion of teachers identified as having misophonia based on predefined classification criteria using the Amsterdam Misophonia Scale-Revised (AMISOS-R). The AMISOS-R total score ranges from 0 to 40, with higher scores indicating greater misophonia severity. Misophonia severity is classified as none, mild, moderate, or severe according to established cutoff values.

    Time frame: Baseline (single assessment)

  2. Prevalence of Hyperacusis Among Teachers

    The proportion of teachers identified as having hyperacusis based on predefined classification criteria using the Khalfa Hyperacusis Scale. The scale consists of 14 items scored on a 4-point Likert scale, with a total possible score of 0-42. Participants are classified as having "no hyperacusis" (≤15), "suspected hyperacusis" (16-28), or "hyperacusis" (≥29).

    Time frame: Baseline (single assessment)

Secondary outcomes

  1. Severity Levels of Misophonia Symptoms

    Distribution of teachers according to misophonia severity levels (none, mild, moderate, severe) based on the AMISOS-R. The AMISOS-R total score ranges from 0 to 40, with higher scores indicating more severe misophonia symptoms.

    Time frame: Baseline (single assessment)

  2. Severity Levels of Hyperacusis Symptoms

    Distribution of teachers according to hyperacusis severity levels ("no hyperacusis," "suspected hyperacusis," "hyperacusis") based on the Khalfa Hyperacusis Scale. The scale has a total score range of 0-42, with higher scores indicating more severe hyperacusis symptoms.

    Time frame: Baseline (single assessment)

Other outcomes

  1. Association of Misophonia and Hyperacusis with Occupational Stress

    Distribution of misophonia (AMISOS-R) and hyperacusis (Khalfa Hyperacusis Scale) severity levels according to teachers' self-reported occupational stress. Misophonia and hyperacusis severity will be classified using the same criteria as above. This outcome will examine the potential relationship between auditory sensitivity and work-related stress.

    Time frame: Baseline (single assessment)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
