Validity & reliability of the Persian version of Grasha-Richmann student learning styles scale

The present study aimed to investigate the psychometric properties of Grasha-Riechmann Student Learning Styles Scale. The participants included 1039 students (421 students in human and 618 students in technical sciences), selected through the stratified sampling method from Tehran University. They answered the Grasha-Riechmann student learning style scale and the data was analyzed with exploratory and confirmatory factor analyses. The findings acquired from exploratory factor analysis (n=561), using principal components analysis with varimax rotation showed that Grasha- Riechmann Student Learning Styles Scale includes six factors: Avoidant, Collaborative, Participative, Dependent, Competitive, and Independent. The factors acquired from confirmatory factor analysis (n=478), as model fit indices indicated, was confirmed by indices in exploratory factor analysis. The internal consistency of each subscale, ranging from 0.58 to 0.80, was at an acceptable level. According to the findings, it seems that Participative Styles Scale to be an instrument qualifying validity and reliability for measuring learning interactive styles.
