Validation of the microbiology literacy instruments in Indonesia: a report of confirmatory factor analysis

Purpose This research aims to validate a microbiology literacy instrument adapted from Jordan. It consists of three main parts, which measure domains of knowledge, attitudes and skills in microbiology. Design/Methodology/Approach A cross-sectional study was conducted on 213 respondents from four universities in Indonesia and analyzed using Confirmatory Factor Analysis with Jeffrey's Amazing Statistics Program software to measure the validity and reliability. Findings The instrument shows quite good validity and reliability and is suitable for use in research. The instrument has good-fit values, confirmed convergent validity and discriminant validity, and quite good internal reliability results. Research limitations/implications The sample used in future research could be increased. Increasing sample feasibility will have an impact on the KMO (Kaiser–Meyer–Olkin) value. Increasing the Kaiser–Meyer–Olkin value aims to increase reliability on a wider scale. Practical implications The validity and reliability report in this study proves that the microbiology literacy instrument tested is feasible and good enough to be used. Future research is expected to increase the number to more than 500 respondents. Social implications The accuracy of measurement, validity and reliability of an instrument is a crucial strategy to increase public literacy in microbiology. Originality/Value This study contributes to providing a microbiology literacy instrument on the theme of the microbiome and its role in the human body by including validation and reliability results. The findings of this research will contribute to the development of microbiology literacy instruments that are useful for the academic community.
