The purpose of the present study was to investigate the reliability and validity of the Turkish version of the Tromso Social Intelligence Scale (TSIS) developed by Silvera, Martinussen, and Dahl (2001). 719 students from Sakarya University participated in the study. Construct validity and criterion related validity and reliability were assessed. Factor analysis for Turkish university students yielded three factor solutions as the original TSIS. Correlation coefficient of the Social Skills Inventory with the TSIS was 0.51. Cronbach alpha, test-retest and split half reliability coefficients were 0.83, 0.80, and 0.75 respectively. Overall results of this study showed that this scale is capable enough to measure social intelligence among university students in a valid and reliable way.
