Introduction: Expectancy-Value-Cost Model represents three important components for predicting academic motivation. This study endeavored to explore the validity and reliability of the Expectancy-Value-Cost scale among the collegiate students.
Methods: As a descriptive-correlational study and to validate the questionnaire using Krejcie and Morgan's Table, 328 students of Hamedan University of Medical Sciences and Bu-Ali Sina University in the academic year of 2018 were selected through cluster random sampling. After translating the Expectancy-Value-Cost (EVC) Scale of Kosovich et al. to Persian, it was presented to students as a 10-item questionnaire. The gathered data were analyzed through exploratory and confirmatory factor analysis, content validity, internal consistency, and split-half reliability coefficient.
Results: Exploratory factor analysis extracted positive motivation and cost as the two major components of the scale. Moreover, the results of confirmatory factor analysis confirmed the construction. The content validity was 0.79 based on the CVI index. To examine the reliability of the scale, the Cronbach's alpha value for each of the factors was 0.79 and 0.76, respectively. The split-half reliability coefficient was computed 0.76.
Conclusion: Findings revealed that the student Expectancy-Value-Cost scale has good validity and reliability. Therefore, this instruments seems to be applicable for the future studies.
