Objective: To determine the agreement between short test of functional health literacy in adults (S-TOFHLA) and short assessment of health literacy for Portuguese-speaking adults (SAHLPA-18) measurement instruments as a strategy to estimate concurrent validity. Methods: Cross-sectional study conducted with users of the Unified Health System. To test concurrent validity, an agreement approach with a weighted Kappa test for qualitative data was applied. Results: 372 individuals participated. It was found that 66% and 62% of these did not have an adequate level of literacy through SAHLPA-18 and S-TOFHLA, respectively. There was a strong correlation between the instruments (p<0.001; r=0.60), however 65.3% agreement, considered weak (Kappa=0.35; p<0.001). Conclusion: SAHLPA-18 and S-TOFHLA instruments have different constructs and poor agreement. The use of different instruments is indicated in research to measure the level of literacy and the development of instruments specific to health conditions that allow obtaining results close to the real context of individuals.
