Standardization of Persian version of persistence questionnaire: Validity and reliability assessment

Perseverance is related to many personality, behavioral and educational variables, and hence the need for a questionnaire in Persian language to measure perseverance is felt. This research was conducted with the aim of standardizing and examining the psychometric properties of the Persian version of the Persistence Questionnaire.

The current research is practical in terms of purpose. In terms of the type of survey data collection and in terms of methodology, it is considered as a test-making study, which has been carried out in the general format of a descriptive research project. The statistical population in this research included all managers and employees of non-governmental organizations in Tehran in 1401. The research sample included 865 managers and employees who were selected by cluster method. The data was collected using Duckworth (2008) perseverance questionnaire. In this research, correlation methods, goodness of fit study, factor analysis and reliability analysis (Cronbach's alpha method) were used. Data were analyzed using LISREL 8.80 and SPSS.22 software.

Based on the data analysis, the current research identified 2 factors (interest and effort) that explain 60.92% of the persistence variable. The results of confirmatory factor analysis showed that the fit indices of the model are in a favorable condition. In addition, Cronbach's alpha coefficient for the subscales was calculated between 0.74 and 0.82.

According to the appropriate statistical analyzes and the results, it seems that the Persian version of the persistence questionnaire (Grit-S) has good validity and reliability and can be considered an efficient tool in this field.
