Abstract
Objective: To investigate the normative data of the Brazilian Portuguese version of the instrument for measuring health literacy European Health Literacy Survey Questionnaire short-short form (HLS-EU-Q6) in Brazilian adults. Methods: This is a methodological study in which the normative data of scores of HLS-EU-Q6 was evaluated in a sample of 783 adult users of the Brazilian public health system (SUS). The normative analysis went through three stages: descriptive analysis of the items and the instrument scores; analysis of the distribution of the score and confirmation that the cutoffs established in the distribution were able to effectively identify the participants in each range. Results: It was observed that all instrument items had a median of 3 and the median of the total score was 17 points. The results suggest that a model with 3 cutting lines and with different scores two proposals by the authors of the original study turned the classification capacity of the instrument more accurate for this population. Conclusion: It is concluded that the classification criteria of the HLS-EU-Q6 to be used in Brazilian adults should be different from those proposed by the authors of the original study, so as not to generate biases in the measurement of health literacy levels in this population.
