Validation method of research instruments for Dental Radiology curriculum study / Método de validação de instrumentos de pesquisa para estudo do currículo de Radiologia Odontológica

ABSTRACT

Dental radiology is an important subject to Dental undergraduate education. Along with other disciplines, it plays a key role in diagnostics, the starting point for patient care. In this way, a specific international guideline for Dental Radiology curriculum was published in 2007. The aim of this study was to develop and validate two distinct instruments, a self-administered online survey, and an interview script, both designed for dental radiology education research. The processes for developing and validating the instruments are described, and the final documents are presented. There were several steps in the validation process of the research instruments in this study, such as translation, cultural adaptation, expert evaluation, read-aloud sessions and pilot testing. This detailed process guarantees control of the variables and helps to avoid bias in regard to the interview and the quantitative/qualitative method analysis (AU).
