Introduction:
There is a variety of questionnaires to measure the level of physical activity. The International PhysicalActivity Questionnaire (IPAQ) has been widely used; however, this has not been validated in electronic format yet.
Objective:
To identify the correlation between the IPAQ long version in print and electronic versions.
Methods:
Study participants were 218 students at a private university, 109 of each gender (age ≤ 25 and ≥ 26). In the first stage, the participants were given prior information about filling out the form IPAQ-L (printed version); after that they completed the electronic version (WebIpaq).
Results:
No significant difference was found on comparing the print and electronic versions of the IPAQ-L. The same occurred in relation to the Practice of Habitual Physical Activity (PHAF) for the ratios by chi-square (X²). Excellent reproducibility was verified by the intraclass correlation coefficient (ICC), reaching values higher than 0.82 (95% CI: 0.68-0.90, age ≥26 years) and 0.90 (95% CI: 0.87-0.93) in the combined analysis. In the weighted Kappa index agreement was substantial, ranging from 0.62 (95% CI: 0.41 to 0.77, males) to 0.67 (95% CI: 0.53 to 0.81, age ≤ 25 years). This shows high agreement on the Bland and Altman analysis.
Conclusion:
Considering the results of this study, it can be inferred that the electronic format of the IPAQ-L meets the assumptions of reproducibility and agreement, providing modern and effective alternative in the analyzes of Practice of Habitual Physical Activity.
