An evaluative study of reliability and validity of Grit 12 item scale in Indian Context
Background: Grit refers to determination to achieve long term goals of life despite of unfavorable and unavoidable circumstances. It is implicated as the energetic working to challenges, along with preserving efforts and interests over the time, in-spite of facing barriers, hardships, and failures in the way of progress. The construct of grit comprises of two dimensions: consistency of interestsand perseverance of effort. The grit scale by Duckworth, Peterson, Matthews, and Kelly (2007) is originally developed to measure grit among Ivy League undergraduates. In present study researcher made an attempt to explore whether this two-factor model of grit to Indian sample.
Method: The alternative model of grit was tested by employing confirmatory factory analysis (CFA) in AMOS 19.0. For this purpose, maximum likelihood techniques were used. 530 senior secondary school students from Himachal Pradesh, Northern India, completed the 12- item survey of grit.
Results: The confirmatory factor analysis of the grit revealed that the 12 item, two factor model of grit determines a good fit model on the Indian sample. The results revealed that the grit scale possesses a good psychometric property on Indian sample which is evident from calculated internal consistency and composite reliability. The results also revealed that the grit scale have a good construct validity, as calculated AVE of all the factor was 0.50.
Conclusion: From the analysis it is evident that the grit scale possesses adequate psychometric properties in Indian sample. The instrument of grit can be considered as a unitary construct in the developing country like India.
