The Tromsø Social Intelligence Scale: Factorial Structure and Reliability of the Persian Version of Scale in the Students Population

The purpose of the present study was to investigate the factorial structure and reliability of persian version of the Tromsø Social Intelligence Scale (TSIS). First, the scale was translated into Farsi. Then, it was retranslated into English and compared with the original version to find and correct the gaps between the translated version and the original version. Finally, after the pilot study and resolving the mistakes, the final questionnaire was carried out for sample group including 413 students studying in Humanities in Tabriz Payame Noor University (304 female, 109 male). In this study, Exploratory Factor Analysis (EFA) was conducted on the 21 items of the TSIS, using a Principle Component Analysis, with Varimax Rotation. Investigation of Scree plot showed three factor solutions. As in the original scale, these factors were called Social Information Processing (SIP), Social Skills (SS) and Social Awareness (SA). The reliability of the Tromsø Social Intelligence Scale was calculated by internal consistency (cronbach’s alpha) and test- retest methods. Cronbach's Alpha coefficient was 0.75 for the whole scale and 0.73, 0.66 and 0.64 for SIP, SS and SA, respectively. Also Test- retest reliability coefficient was 0.81 for the whole scale and 0.76, 0.86 and 0.66 for SIP, SS and SA, respectively. Cronbach's Alpha and test- retest coefficient showed that reliability of factors is acceptable.
