Academic Motivation Scale: Validity in Portuguese Public Higher Education

Abstract This research aimed to study the psychometric properties and subsequent validation of the Academic Motivation Scale proposed by Guimarães and Bzuneck (2008), in Portugal using two samples, the sample A constituted by 568 students of public higher education and the sample B constituted by 589 public higher education students, with a national scope. SPSS 25 and AMOS 25 software were used for data processing. Two confirmatory factor analyzes were conducted in each sample and a multiple group analysis, and the results pointed to the validity of the re-specified scale of the motivation evaluation in higher education, especially high correlations between the dimensions Extrinsic Motivation by Integrated Regime and Intrinsic Motivation, Extrinsic Motivation by Integrated Regulation and Extrinsic Motivation by Introjected Regulation and by Extrinsic Motivation by External Regulation and Demotivation. It was verified that the proposed scale model is invariant.
