Development and validation of a COVID-19 risk perception scale in Peru.

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
OBJECTIVES.: Motivation for the study. Risk perception of COVID-19 is a construct that varies according to the characteristics of the population in each geographic area; however, there is no validated scale to measure this construct in the Peruvian population. Main findings. A COVID-19 risk perception scale composed of two dimensions (cognitive and emotional) was designed and validated using qualitative and quantitative techniques. Implications. Having a valid and reliable instrument will help identify the variation of risk perception of COVID-19 according to contextual and psychological factors in the Peruvian population. . To develop and validate a risk perception scale for COVID-19 (PR-COVID-19-PE) in the Peruvian population. MATERIALS AND METHODS.: Psychometric cross-sectional study conducted in 2022. In phase 1, in order to design the scale, we carried out a theoretical review and a documentary review of scales, we also used focus groups as well as an expert panel. Phase 2 included expert judgment and a pilot test. A virtual survey was conducted among 678 Peruvian adults during phase 3. A confirmatory factor analysis was carried out as well. We used a correlational analysis (Pearson's r) with a valid risk perception scale and the COVID-19 fear scale to determine criterion validity. RESULTS.: The PR-COVID-19-PE has two dimensions (cognitive and emotional) and showed good fit during construct validity (x2/gl=2.34, Comparative Fit Index=0.96, Tucker-Lewis Index=0.96, Root Mean Square Error of Approximation= 0.05 and Standardized Root Mean-Square=0.07) and optimal internal consistency (ώ=0.88). Likewise, the PR-COVID-19-PE showed correlation with another COVID-19 risk perception scale (r=0.70, p< 0.001) and a fear of COVID-19 scale (r=0.41, p<0.001). In addition, it presents metric and scalar invariance by both sex and educational level. CONCLUSIONS.: The PR-COVID-19-PE scale showed adequate reliability and content, construct and criterion validity. It is an instrument that can measure COVID-19 risk perception in similar populations. However, further studies are required for different populations.
