Objective: social well-being is the appraisal of one’s circumstances and functioning in society. The aim of the present study was to develop the short form of one of the most widely used social well-being scales (developed bye Keyes, 1998) to be used in Iranian samples. Short forms are more useful when there are time limits or participants lack patience. The development of the short form of the social well-being scale was intended to be based on the improvement of the factorial validity of the subscales. Method: Four hundred and fifty four students (261 girls and 193 boys) of Tehran University were included. The mean age was 22.18. All students were asked to complete Keyes’ 33-item social well-being scale. Exploratory and confirmatory factor analyses were used to analyze the data. Findings and Results: The use of 18 items of the social well-being scale as the Persian short form of social well-being scale was supported by the analyses. All in all, results of this study indicated that the Persian short form of social well-being scale has an acceptable and clear factor structure and its statistical characteristics are better than the long form
