This article describes the entire process of validating the data collection instrument of the CAPPLE project. The validation of the instrument (an online survey) aims to ensure the reliability, validity, relevance and functionality of the collection process. Hence, a validation method based on three complementary procedures has been chosen: expert judgement by eight experts in three consecutive rounds; a round of cognitive interviews with 24 subjects on 10 critical items, and a pilot study with 400 invited subjects, of which 224 are considered the final sample. Following the completion of the three methods described, we get an instrument that meets the validation criteria, configured by four basic dimensions (self-perception, information management, management of the learning process and communication) and that could be considered as a very useful tool in the study of Personal Learning Environments of university students.
