ABSTRACT
The Academic Grit Scale (AGS) precisely measures grit in the academic domain. However, the AGS has only been adapted to a limited number of samples, and little evidence of its reliability and validity has been presented. The current study consists of two separate studies addressing the AGS. In Study-1, the 10-item unidimensional structure of the AGS was confirmed by confirmatory factor analysis in a Turkish sample of children aged 8–11 years. Different reliability coefficients supported the high reliability of the AGS. In Study-2, two models addressing the relationship between academic grit, science attitude and school belonging were tested. Structural equation modelling showed that science attitude mediated the relationship between academic grit and school belonging. Adapting AGS to different cultures is valuable in highlighting academic grit’s social and cultural structure. In addition, the present study revealed the relationship between academic grit, science attitude and school belonging for the first time. This indicates that academic grit can be addressed in different contexts across disciplines.
