SARA application for treating people with tuberculosis: a methodological study

A methodological study with three phases: preparation of the concept map according to the manuals of the Brazilian Ministry of Health and the World Health Organization; development of the application, with navigation and prototyping design; and based on Pasquale’s method, content validation was performed by health experts in an online environment with semantic validation by the target audience, individuals with tuberculosis treated in a health unit in Natal, Rio Grande do Norte, Brazil, using the Delphi technique, analyzed using the Content Validity Index.

Results

The final version of the application was developed after three rounds of the Delphi technique. In the third Delphi round, the overall Content Validity Index was 0.92, as rated by seven expert evaluators in the North, Northeast, Central-West, South, and Southeast of Brazil, and validated by six patients being treated for tuberculosis, obtaining an overall Content Validity Index of 0.98.

Conclusion

The application was validated regarding content and semantics by expert evaluators working in the area of tuberculosis in more than one region of Brazil, from a multidisciplinary perspective, and by the target audience for which it is intended. It was considered an important tool to contribute to control strategies for the treatment of tuberculosis.
