The Adaptation of the State Self-Compassion Scale Long and Short Form to Turkish Culture: Validity and Reliability Study

Study 1. This study aimed to examine the psychometric properties of the Turkish version of the State Self-Compassion Scale-Long Form (SSCS-L). The research was conducted on 536 individuals. As a result of the linguistic equivalence study, a positive significant correlation ranging from r=.384 to .909 was found between the original and Turkish items of the study. As a result of CFA, fit index values were found as (χ2/sd= 386.886/120=3.224, p=.00), RMSEA=.064, NFI=.915, CFI=.939, IFI=.940, RFI=.892, GFI=.923 and SRMR=.046. The Self-Compassion Scale was used to test the criterion-related validity. Spearman's rank correlation coefficient was found to be .841. The internal consistency coefficient of the factors of the scale was calculated between .742 and .923. The item-total correlations ranged from .39 to .80, while the item discrimination index values of the upper-lower group ranged between 8.22 and 22.3. The research findings demonstrated that the State Self-Compassion Scale-Long Form is a valid and reliable instrument in Turkish culture.Study 2. This study aimed to examine the psychometric properties of the Turkish version of the State Self-Compassion Scale-Short Form (SSCS-S). The research was conducted on 536 individuals. As a result of the linguistic equivalence study, a positive significant correlation ranging from r=.505 to .797 was found between the original and Turkish items of the study. As a result of CFA, fit index values were found as (χ2/sd= 31.660 /9=3.518, p=.00), RMSEA=.075, NFI=.954, CFI=.967, IFI=.967, RFI=.924, GFI=.979 and SRMR=.033. The Self-Compassion Scale was used to test the criterion-related validity. Spearman's rank correlation coefficient was found to be .873. Cronbach's alpha coefficient was calculated .782 for the scale. The item-total correlations ranged from .36 to .64, while the item discrimination index values (t) of the upper-lower group ranged between 12.69 and 21.65. The research findings demonstrated the State Self-Compassion Scale-Short Form is a valid and reliable instrument in Turkish culture.
