Abstract

The aim of this study was to validate an instrument designed for oral health professionals (dentists, hygienists or assistants) on compliance with measures to combat Covid-19 in dental services according to the guidelines of the Brazilian National Health Surveillance Agency. The methodological study was divided into five stages: 1) face and content validity: carried out by eight experts in the field followed by a pilot study with 35 oral health professionals; and, 2) validation of the psychometric properties measured among oral health professionals working in the states of the Southern Region of Brazil, who answered 37 questions of the instrument (n=1824), with assessment of: a) internal consistency using the Cronbach's Alpha coefficient and the item-total correlation; b) reproducibility measured by test-retest among 52 participants; and, c) construct validity by b means of  divergent and convergent correlation analysis and exploratory factor analysis. In terms of face and content validity, questions were reduced, regrouped and divided, in addition to adaptations of form and content in items and answers. On 34 items, agreement was substantial/almost complete (intraclass correlation coefficient>0.60) Reproducibility was adequate (p=0,45). Reliability analysis indicated exclusion of six items due to item-total correlation <0.20 and one item due to factor loading <0.30. The instrument with 30 items showed good internal consistency (Cronbach's alpha=0.86). Analysis of the main components  showed five dimensions that explained 51.1% of the variance (p<0.001). The convergent criterion validity had a moderate positive correlation (p<0,001). The instrument developed was validated by presenting adequate psychometric properties. In this sense, the instrument can be used for oral health professionals in other locations or at other times of the Covid-19 syndemic in Brazil.
