[Design and semantic validation of a new instrument to assess policy transfer of directly observed treatment for tuberculosis].

Objective: To design and semantically validate an instrument to evaluate the transfer of directly observed therapy (DOT) as a policy for tuberculosis control taking into consideration the experience of mid- and higher level health care workers.
Methods: This methodological investigation was developed in two stages: literature review to design the first draft of the instrument; and semantic validation of the first draft using questionnaires adapted from the DISABKIDS® project. The information obtained was analyzed using quantitative (descriptive statistics) or qualitative (content theme analysis) methods.
Results: Twenty-four mid- and higher level health care workers engaged in tuberculosis control participated in the study. The instrument was considered important for the work of study participants. The answers provided by participants led to changes in both the structure and content of the instrument. The process resulted in a final, semantically validated questionnaire.
Conclusions: Semantic validation is important to ensure the applicability of assessment instruments, as shown by the contributions provided by participants. The instrument whose semantic validation was described in this study will now be assessed in terms of psychometric characteristics and usefulness to measure the transfer of DOT to health professionals as a tuberculosis control policy.
