Interrater reliability in the application of the VPAS-PB: analysis among experienced judges
1Hospital Central Aristarcho Pessoa, Corpo de Bombeiros Militar do Estado do Rio de Janeiro - CBMERJ - Rio de Janeiro (RJ), Brasil.
Purpose:
This study analyzes the interrater reliability of the Brazilian Portuguese version of the Vocal Profile Analysis Scheme (VPAS-PB) applied by experienced judges.
Methods:
Ten adult participants with no vocal or hearing complaints produced a standard sentence and two personal stories, which were recorded and later evaluated independently by three speech-language-hearing pathologists trained in phonetics and experienced with the protocol. Interrater reliability was estimated using internal consistency analysis (Cronbach's Alpha).
Results:
Analysis with Cronbach's alpha indicated good to excellent internal consistency for most vocal settings, with lower agreement for "lip spreading" and "falsetto."
Conclusion:
This study demonstrates that the VPAS-PB has high interrater reliability and excellent internal consistency across most vocal settings, reinforcing its applicability in the Brazilian Portuguese context.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
