: The Committee for Ethics and Research Integrity of the Faculty of Education of the University of Trnava does not require researchers to apply for ethical approval for studies involving the collection of subjective opinions of adults on a voluntary basis and without the collection of personal data. All studies complied with the 1975 Declaration of Helsinki and its derivatives. Confirmation of this compliance was later reaffirmed by the Chairman of the Committee for Ethics and Research Integrity of the Faculty of Education of the University of Trnava on April 23, 2025.
: Informed consent was obtained from volunteer participants in the quantitative phase of the study via personal/oral form: students were informed about the objectives and verbally agreed to participate (Survey conducted in April – May 2024). Answering the questionnaires by students and their statistical evaluation took place completely anonymously.
: With deepest sadness, we dedicate this work to the memory of the victims of the shooting at the Faculty of Arts of Charles University (December 21, 2023), among whom were several students of communication for the deaf.
