Elaboração e validação de um guia fonoaudiológico para ações de saúde vocal do professor

Abstract

NTRODUCTION: Speech-language pathology has a relevant focus on the voice of the teacher. Both practice and research with this population indicate a high vocal risk of vocal changes and high rates of dysphonia. Currently there are several teacher health vocal actions, including those guaranteed by law. An example of progress in the area occurred in 2018 with the Ministry of Health's official approval of the DVRT Protocol - Work-related Voice Disorder OBJECTIVE: to elaborate and validate a didactic content guide to subsidize the vocal health actions of the teacher, which aims to contribute with research in the field and fill the gap found in the current literature, increasingly encouraging evidence-based practice. METHODOLOGY: this is a cross-sectional qualitative and quantitative study. The chosen instrument was a guide, which covered three stages: parameter selection, elaboration and validation. The first stage was accomplished through a research in the scientific literature of the area, which provided the items that composed the first version of the didactic content guide. After elaboration, the guide was analyzed by an expert bank composed of five speech therapists with experience in the area. At that moment two contents (auditory training and laryngeal diseases) were excluded, leaving 18 items in the consensus version of the guide. Next, the validation stage was carried out, based on psychometrics, searching for evidence of validity through the analysis of a committee of judges composed of another group of five speech therapists with practical and academic experience in the area of the teacher's voice. According to the committee's assessment, the items were considered clear. The statistical analysis consisted of several tests such as the IVC (Content Validity Index) used as criterion for selection or exclusion of didactic contents. In the elaboration stage the Kappa coefficient was calculated in order to verify the agreement between the subjects, and, as a result, the values obtained indicate a low but significant agreement. In the validation stage, the IVC was calculated again and the Cronbach Alpha test, which confirmed the reliability of the guide. RESULTS: Following the proposed methodology, a guide was developed for the validation of a didactic content for vocal health of the teacher that was called the Vocational Health Teacher's Guide (GSVP).
