OBJECTIVES: to develop and validate the content and construct of an instrument for assessing vaccine hesitancy against COVID-19.
METHODS: methodological study, developed in three stages: i) construction of the instrument; ii) content validation by judges; and iii) validation of the construct by the target audience. The Health Beliefs Model was used to develop the instrument.
RESULTS: the instrument was constructed with 45 items. Seven items were excluded because they had a content validity coefficient of less than 0.8. Exploratory and confirmatory factor analyses were carried out to validate the construct. The Kaiser-Meyer-Olkin was 0.801 and Bartlett's test of sphericity showed p<0.001. Six items did not achieve sufficient factor loading to remain in the instrument. The confirmatory factor analysis revealed a valid and reliable instrument.
CONCLUSIONS: the developed instrument shows evidence of validity and is therefore recommended for research aiming to assess the reasons for COVID-19 vaccine hesitancy.
