Development and content validation of a mobile application for monitoring latent tuberculosis treatment

BACKGROUND: Non-compliance with latent tuberculosis infection (LTBI) treatment is a reality. The objective of this study was to develop and validate an mobile device application for monitoring the treatment of LTBI. METHODS: We defined the requirements, elaborated on the application's conceptual map, generated implementation and prototyping alternatives, and validated content. RESULTS: Feedback on the validity of content were: “usefulness, consistency, clarity, objectivity, vocabulary, and precision” from professionals, and “clarity” from patients. CONCLUSIONS: The application proved to be easy to understand, according to the assessment of both professionals and people undergoing treatment for LTBI.
