Abstract

Tuberculosis is a global concern, mainly in Indonesia, which is still one of the top five contributors to the illness. The disease can be avoided by increasing Tuberculosis Literacy among persons living with Tuberculosis (PLWTB) and those around them. However, measures to assess TB literacy are inaccessible and must be created. This study aims to determine the validity and reliability of a tuberculosis literacy test in urban settings. The TB literacy instrument was developed using the MEASURE Approach, a practical guide to instrument development and score validation in the social sciences. Ten young people evaluated the instrument for face validity and expert judgment. The validity analysis included 1411 participants from urban communities. The twenty questions about tuberculosis literacy were created by combining a matrix of four dimensions applied to three health areas. The validity study revealed that all questions are valid and reliable (LF>0.3, CR>0.7, RMSEA≤0.08). Except for the applied domain (L14-L20), all domains have an AVE greater than 0.5. It may be concluded that the instrument is reliable and valid for measuring tuberculosis literacy in urban areas.
