Rasch Model-Based Adversity Quotient: A Potential Instrument for Assessing Madrasah Students’ Literacy

Abstract

Adversity quotient used in measuring a person's ability to respond to difficulty. Sub dimensions of adversity quotient consist of control, ownership, reach and endurance. This study aims to validate the instrument of adversity quotient for Postgraduate students by using the Rasch modelling approach that is believed to have advantages over classical test theory. This study used survey method. The data was obtained from 500 Postgraduate students. The data was analyzed by the Rasch model and assisted by Winstep software Version 3.73. The results of the study showed the instrument reliability index (a = 0.82), with respondent reliability (a = 0.79), and item reliability (a = 0.99). This instrument can show 30.8% of the respondents' variance, which means it can be a guarantee of the construct validity of the instrument (item) as expected, so that it can describe the quotient of Postgraduate students in a good, accurate, and accountable manner and can be used for assessment, as well as research.
