RESUMO
Abstract Aims: To present to the scientific community the transposition of the printed version to the electronic version of the WebCas questionnaire. Methods: The transposition of the printed version to the electronic version of the WebCas questionnaire was carried out using the service of a computer programming professional. Through a response interface, the students had access to instructions to respond to the questionnaire. The MySQL 5 method was used to store the information, allowing the generation of reports. To record the responses, students were instructed to click on the chosen option. In case of error, they should choose another option, changing the option chosen previously. The "next" arrow indicated that the individuals being evaluated could change the page. Results: The WebCas questionnaire presented several functionalities related to its presentation and filling out process. In the restricted access to maintenance activities, it is possible to visualize 8 icons: 1 - questionnaire (information regarding the completion and development methodology of the questionnaire); 2 - students (registration information, anthropometric data and student code); 3 - activities (name of the activity, the domain such activity is inserted, intensities and values in MET's); 4 - questions (statement and category of the question); 5 - graphs (showing the results of each question in the bar or pie format graphs); 6 - reports (reports export). Conclusion: The WebCas questionnaire is a technological resource that will assist health researchers in the collection, storage, and preliminary processing of information regarding health-related behaviors in schoolchildren.
