CAMARGO, Diana Marina et al. Reliability of the 3-day physical activity recall (3DPAR) in schoolchildren from 5th and 6th grade. Rev. Univ. Ind. Santander. Salud [online]. 2010, vol.42, n.1, pp.34-47. ISSN 0121-0807.

Purpose: To evaluate the test-retest reliability of the 3-day physical activity recall (3DPAR) in printed and digital format. Material and methods: An evaluation of a diagnostic test study was done; 121 students of 5th and 6th, 36.9 % male gender, average of age 10.7 ± 0.9 years, took part in this study. Reliability was analyzed by the intraclass correlation coefficient (ICC) and the levels of agreement were established with Bland & Altman plot (B&A), based on averages of blocks for each level of intensity and day of week. Results: The printed format showed ICC between 0.2 and 0.5 for very hard physical activity (VHPA), between 0.2 y 0.3 for hard physical activity (HPA); the digital format was answered by 59 students and showed ICC between 0.2 and 0.6 for the VHPA and HPA. We found a good level of agreement between the two formats. Conclusions: SThe results of this work are the beginning of the evaluation of the questionnaires for assessment of physical activity in children and adolescents in our setting. The reliability findings showed the urgency to realize the evaluation in oldest children ages and possibly, asking for usual activities instead of those of three immediately previous days.
