The SMTSL was translated into Turkish by Yilmaz & Cavas (2007) and determined to be a valid and reliable tool for Turkish students. In order to confirm the original factor structure of the instrument, a principal component analysis with Equamax rotation was performed. The results of the factor analysis indicated that the factorial structure of SMTSL was the same as that observed by Tuan Chin and Shieh. Two items (items 15 and 21) were deleted from the Turkish instrument because factor loadings were lower than 0.3 so that the final Turkish version consisted of 33 items, in 6 scales. The reliability of the whole instrument and the scales was as shown at Table 2.
