Developing, Validation, Reliability and Normalization of Expectancy- Value- Benefit- Cost Scale among Bu-Ali Sina University Students

This study was conducted with the aim of developing, validation, reliability, and normalization of Expectancy- Value – Benefit - Cost Scale among students of Bu-Ali Sina University. The research method was descriptive-correlational, and the statistical population included all students of Bu-Ali Sina University in the academic year of 2019-2020. The sample size included 395 students were randomly selected through multi-stage cluster sampling method, and they completed the researcher-made scale. Methods of analysis included: exploratory and confirmatory factor analysis, content validity, and concurrent validity, and Cronbach alpha coefficient. The results of exploratory factor analysis extracted 5 factors named expectation, value, benefit, psychological cost, and situational cost.  Moreover, first and second order confirmatory factor analysis confirmed the results of exploratory factor analysis of the scale. The estimated Cronbach alpha reliability coefficients for the whole scale was 0.848, and for expectation, value, benefit, psychological costs, and situational costs were 0.898, 0.899, 0.793, 0.862, and 0.778 respectively.
