Psychometric Properties of the Student Version of the Academic Motivation Scale

The aim of this study was to investigate the psychometric properties (validity and reliability) of the student version of the Academic Motivation Scale.

This study was a psychometric correlation study. The sample consisted of 400 students of the Islamic Azad University, South Tehran Branch, who were selected by available sampling method and completed the student version of the Vallerand, Pelletier, Blais, and Briere (1992) Academic Motivation Scale. Data were analyzed using expolary factor analysis, confirmatory factor analysis, Cronbach's alpha and retest.

The results of exploratory factor analysis showed 23 items 7 intrinsic motivation factors (with the amount of variance explained 12.85), achievement (with the amount of variance explained 11.89), identified (with the amount of variance explained 10.44), amotivation (with an explained variance of 10.40), extroversion (with an explained variance of 10.19), stimulation (with an explained variance of 7.9), and knowledge (with an explained variance of 6.57). The results of confirmatory factor analysis confirmed the findings of exploratory factor analysis. Fit indices were obtained in both models of confirmatory factor analysis at the appropriate level of 0.001. The overall reliability coefficient of the scale was obtained by Cronbach's alpha (0.88) and retest method (0.86) for the desired level.

The results of the study showed that the student version of the Academic Motivation Scale has good validity and reliability and can be used to measure academic motivation in students.
