The present study aimed to develop a scale to measure the writing self-efficacy of non-native students of Turkish origin (Uzbek, Kazak etc.) who come from abroad to Turkey for education. Firstly, the distinctiveness of each item in the item pool was examined in the data analysis. Exploratory and confirmatory factor analyses were used in the second phase of the data analysis. As a result of the analysis, a scale with 2 factors and 17 items was obtained. These two factors explain 58.45% of the variance. The factor loads of the items vary between .479 - .867. Consistency index values obtained as a result of CFA were found to be GFI=0,90, AGFI=0,86, CFI=0,99; NFI= 0,97, RMSEA=0,049 and SRMR=0.041; (X2=158.07, df=114, p<.01); and the X2 / df ratio was found to be 158.07/114=1.39. The Cronbach alpha reliability coefficient of the scale was calculated as 0.81 and 0.93 for sub-scales and 0.94 for the entire scale.© 2013 IOJES. All rights reserved
