Presentation and Evaluation of the Teacher's Vocal Health Guide

in order to contribute of the collective actions of the teacher's vocal health, the specific goal was to build a guide gathering the appliable didactic content in these actions. That being, the stages performed in the instrument elaboration of the denominated Teachers' Vocal Health Guide (TVHG) will be presented.

The elaboration process of the guide is composed of three stages: (1) parameter selection to compose the guide based on a literature review; (2) submission to a specialist examining board, with the calculation of the Content Validity Index (CVI) and the Kappa agreement coefficient; (3) content validation - the instrument was submitted to an analysis of a judges committee, and from the results the Cronbach Alfa coefficient and the CVI were calculated.

The elaboration of the TVHG underwent three stages. In the first stage, called parameter selection, 20 didactic contents were found, consisting of 14 theoretical and six practices. In the second stage, an evaluation of the guide was performed by a specialist examining board and two contents were excluded since their CVI was below 8. The result of the Kappa Coefficient Calculation was 0.281. In the third stage, the TVHG underwent evaluation of a new group denominated judges committee, and the items were punctuated as very relevant and completely relevant. The result of the Cronbach Alfa coefficient for the instrument with 18 items was 0.721, and this value categorizes the instrument as valid. It is necessary to continue the process of instrument validation, possibly investigating the applicability of TVHG in the teachers' opinion.

The current study presents the TVHG from the description of the three stages performed to elaborate a systematized instrument denominated TVHG, which suggests a gathering of didactic content that are appliable in collective actions of vocal health with this professional category.
