Abstract
Objective: The present research aims to study the factor structure, reliability, and validity of the Successful Intelligence Scale. Method: Using the multi-stage cluster sampling method, 500 (including 175 female and 325 male) subjects were selected from among public school students in Karaj. Results: The exploratory factor analysis was performed using the principal component method. The results confirmed three factors of successful intelligence (i.e. analytical, creative, and practical intelligence) as well as the principal factor. Reliability of the scale items was examined using Cronbach’s alpha coefficient, and its validity was investigated using factor analysis. Internal consistency of the questionnaire was acceptable, and the Cronbach’s alpha for the subscales was between 0.74 and 0.81. Also, the confirmatory factor analysis results confirmed that the structure of the scale had an acceptable fit to the data, and that the goodness-of-fit index for the model was observed. Conclusion: The results of confirmatory factor analysis were almost close to that of studies done in the original cultural context. Validity and reliability of the scale were also close to that of previous researches. Considering the desirable psychometric property, therefore, this scale is an appropriate instrument for measuring the students’ successful intelligence.
