Abstract
FLEITES DID, Tania Yanet et al. Validation of evaluative instruments of knowledge on oral health. Rev.Med.Electrón. [online]. 2021, vol.43, n.1, pp. 2808-2821. Epub Feb 28, 2021. ISSN 1684-1824.
Introduction:
the design of measuring instruments is a complex process that requires a rigorous preparation to obtain a test answering the demands generating its construction. Validity is a process that requires reliability, it is currently of great importance since it allows the elaboration of instruments that allow measuring parameters with greater veracity.
Objective:
to validate the content of instruments for evaluating oral health knowledge in preschool children, teaching staff and families.
Materials and methods:
an evaluative study was carried out during the time period 2017 - 2019. Interviews addressed to children and questionnaires to teaching staff and families, both instruments for measuring knowledge on oral health, were assessed: Content validation was performed using the Moriyama method and the Delphi technique.
Results:
the validation of the instruments showed that 100% of the questions were reasonable and understandable, sensitive to variations, with justifiable basic assumptions, with clearly defined components that are derived from data feasible to obtain. In the Delphi validation, 100% of the questions were evaluated with categories of very adequate and quite adequate.
Conclusions:
The evaluated instruments turned out to be reliable through content validity, which increases the rigor of the research process.
