Investigating the psychometric properties of the San Diego wisdom scale

Wisdom is one of the highest virtues and in the vast range of social activities, it ultimately improves itself and society. this study was aimed to examine the psychometric properties of The San Diego Wisdom Scale (SD-WISE). For this purpose, a sample of 350 students of Allameh Tabatabai University (223 females and 132 males) was selected by Stratified random sampling. and answered the SD-WISE questions, which consists of the six components of Social Advising, Emotional Regulation, Decisiveness, Insight, Pro-Social Behaviors, Tolerance for Divergent Values. The statistical characteristics, item analysis, validity coefficients, and exploratory and confirmatory factor analysis were used to assess the psychometric properties of the scale. The reliability of the questionnaire was calculated based on Cronbach's alpha equal to 0.81. The correlation between this scale and the three-dimensional wisdom scale was 0.56, which indicates the validity of the questionnaire.The results showed that after several runs of factor analysis and extraction of different solutions, five factors were extracted using the varimax method. Percentage of the variance shared by variables for the five factors, overall, can explain 54.236 percent of the total variance of variables. In addition, the model of confirmatory factor analysis was used to confirm the extracted factors, for which two models were compared and evaluated: the factor structure of the original version and the factor structure derived using the LISREL measurement model. The fit indices showed that the derived five-factor model has better fitness to the data than the original model.
