- Abstract
The objective was to analyse the agreement between the printed version (PV) and electronic version (EV) of an instrument to assess PA in children and to verify the reliability between two applications of the EV. The sample included 230 seven to tenyear-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 concordance) 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 concordance was over 70% and the intraclass correlation was 0.84 (95% CI = 0.78 to 0.89). The electronic questionnaire (WEBDAFA) presented appropriate psychometric indices of agreement and reliability when applied to children aged seven to ten years.
