An Indonesian Version of The Instrument for Measuring Knowledge and Attitudes Toward Antibiotic Among the Population in The Whole Country

In Indonesia, programs designed to enhance the precision of antibiotic utilization necessitate specific tools for gauging knowledge and attitudes among the intended population. This research seeks to create a novel instrument customized to suit the specific requirements of the Indonesian populace and evaluate its psychometric characteristics in the context of measuring antibiotic knowledge and attitudes. This study was performed with forward and backward translation, adaptation testing, and a validation phase in which we distributed the instrument link via Google Forms to six major regions in Indonesia. The translation and adaptation phases, any disparities were resolved through consensus. Validity was determined through known group validity, construct validity, and product-moment correlation. Internal consistency among items was assessed using Cronbach's alpha. In the adaptation phase, additional descriptions were added to the 6 items. In the validation phase, 1147 participants were recruited. The a priori hypothesis in the known group validity is supported. We also found three items that did not meet construct validity. Based on the results of exploratory factor analysis, it is better to use four factors with modified domain names based on items that are incorporated in one factor. Based on the results of the validity test using the product-moment correlation for 11 items in the Attitude domain, all items were declared valid. Cronbach's alpha value in the knowledge domain was 0.791 and in the attitude domain was 0.929. Our instrument is valid and reliable for assessing the general public's knowledge and attitudes toward antibiotics in the Indonesian population.
