Results: The results of exploratory factor analysis revealed ten factors which in total, explained 12.43% of the total variance of the questionnaire. The results of exploratory factor analysis revealed ten factors which in total, explained 74/12% of the total variance of the questionnaire. The results of the confirmatory factor analysis, in addition to confirming the results of exploratory factor analysis, showed that these ten factors ultimately affect the two factors of general orientation social- focused and person-focused.  The reliability of the questionnaire was obtained by Cronbach's alpha (α = 0.91) and test-retest test (0.89). Also, the positive relationship between the factors of this questionnaire and the values in action questionnaire confirmed the convergent validity of the questionnaire.
