Development and validation of an instrument to verify vaccination hesitancy against COVID-19.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesto develop and validate the content and construct of an instrument for assessing vaccine hesitancy against COVID-19.
methodsmethodological 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.
resultsthe 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.
conclusionsthe developed instrument shows evidence of validity and is therefore recommended for research aiming to assess the reasons for COVID-19 vaccine hesitancy.
