The objective was to analyze the agreement between the printed version (PV) and electronic version (EV) of a tool to assess physical activity (PA) in children and to check the reliability between two applications of the EV. The sample included 230 seven to ten-year-old children from two schools (public and private). The sample was divided into two groups: a) analysis of agreement (n = 130), two applications of the questionnaire (EV vs. PV); b) reproducibility analysis (n = 127), two applications of the EV (test-retest). There was no significant difference between the PV and PE in the PA domain (48.6 vs. 46.8). The intraclass correlation coefficient (analysis of agreement) was significant for all types of PA (p<0.05). In the reliability analysis, the difference between the scores of PA test-retest was of 2.70. The agreement was over 70% and the intraclass correlation was 0.84 (95% CI = 0.78 to 0.89). The electronic questionnaire (WEBDAFA) presented appropriate psychometric indexes of agreement and reliability when applied to children ages seven to ten years.
