This study analyzes the factorial structure and reliability of the motivation and learning strategies questionnaire (MSLQ) in a sample of 409 university students between with an average age of 19.08. An Exploratory Factor Analysis was carried out using the Principal Axis Extracting method (AEP). The results identified 9 factors, three fitting the scale of motivation and six fitting the scale of learning strategies. The MSLQ proves to be a reliable instrument for measuring motivation and learning strategies applicable in the research context, however further research is needed to investigate the discrepancies with the factor model proposed by their authors.
