Introduction: There are a few tools validated to assess sedentary behavior in Brazilian children and adolescents. Objective: To evaluate the validity of a questionnaire to measure sedentary behavior in 117 students of both sexes, aged 9 to 15 years, attending five public schools in Curitiba/Brazil. Methods: The questionnaire evaluated the time spent in sedentary activities on both weekdays and weekend days of a typical week. The time spent in sedentary activities was validated against the estimates of sedentary time obtained by accelerometers (Actigraph model GT3X). For data analysis, the Spearman correlation coefficient (rho) and the Bland Altman scatter plot were used between the accelerometer read-out and the questionnaire measurement, with a 5% significance level. Results: The correlation coefficient between the accelerometer read-out and the questionnaire measurement was 0.79 (p <0.00). Validity was higher on weekdays (rho = 0.66), in female schoolchildren (rho = 0.80) and in older schoolchildren (rho = 0.87). The mean difference between the two measurements was 148.96 minutes/week (95% CI: -45.50-343.42) with agreement limits ranging from -1975.02 to 2272.94 minutes/week. Conclusion: The questionnaire analyzed in this study had satisfactory levels of validity and agreement and can therefore be used to estimate the sedentary behavior of students aged 9 to 15 years.
