Abstract

The objective of the study was to carry out the concurrent validity of the WebCas questionnaire to evaluate physical activity (PA) in 140 students (10 to 16 years) divided into four groups, instructed to use an accelerometer and answer the WebCas questionnaire daily, which resulted in 213 days of PA monitoring. Statistical analyses were performed using the Mann-Whitney U-test, scatter plots (Bland and Altmann) and correlation coefficients. The correlation between PA (WebCas) measurements compared to acelerometry measurements (one day) showed low-intensity correlation (r = 0.22; p <0.001), moderate intensity (r = 0.48; p <0.04), an average of three days. Increased correlation was observed for the 5-day PA average (r = 0.67; p <0.01). The WebCas questionnaire presented satisfactory validity indicators.
