Reliability and validity of Indonesian version of career maturity inventory (CMI) form C

Abstract

Career Maturity Inventory (CMI) Form C is an inventory used to measure high school student’s career maturity. Although several studies have measured the reliability and validity of the 24-item CMI Form C that created by Crites and Savickas, there are only a limited number of researches measuring the psychometric properties of the Indonesian version of the CMI Form C. The present study examines the reliability and validity of the Indonesian version of CMI Form C. The study involved sample comprised of 109 high school students, the age ranging from 16 to 18 years old. Utilizing Rasch Model Analysis, of 24 items assessed, only 10 items were fit. The result showed that the item reliability of CMI is r=0.97. This limitation of fit items indicated that there are cultural differences of how Indonesian students perceived the career maturity. Consequently, further study that considering Indonesian culture of CMI need to be conducted before applying it massively in the Indonesia context.
