Psychometric Assessment of the Short Grit Scale (Grit-S) using the Rasch Model in a Malaysian Polytechnic Students’ Sample

Abstract

The study investigated the psychometric assessment of grit questions in the setting of a technical student using the Rasch model. Random sampling techniques were chosen among 468 polytechnic students. The results showed eight Short Grit Scale (Grit-S) items met the requirements of the Rasch model. These items can measure grit for technical students’ context, but there is ample room for further progress in determining the quality of grit items’ development in different settings. In a nutshell, Grit-S needs to generate more items to cater to people with higher abilities so that they can tested with more complex items.
