The study aimed to develop and validate academic motivation measures among university students. The study adopted the correlational method. An available sample of university students selected from the Faculty of Education, Suez Canal University. The study sample consisted of 453 people. The scales responded online to the students after they accepted the informed consent and wrote their data online in the same submission file. The study investigated the factor structures of the Academic Motivation Scale (three-, four, five-, and seven-factor models). The seven-factor model, the four-factor model, and the five-factor model were the most appropriate. According to the convergent validity, it was positively associated with the motives of autonomy and measures of cognitive styles, However, the lack of motivation subscale was nonsignificant with the Cognitive Styles scale and the Self-motivation subscale. The study indicates the psychological validity of the academic motivation scale for university students.
