The study aims to investigate the psychometric properties of the Turkish version of the Forms of Self-Criticizing/Attacking and Self-Reassuring Scale (FSCRS) in clinical and community samples. A total of 269 depression outpatients (71.7% female; Mean age = 28.28, SDage = 9.11) and 305 participants from the general population (54.5% females; Mean age = 43.11, SDage = 9.60) were recruited. Participants completed the FSCRS, the Levels of Self-Criticism (LOSC) and the Beck Depression Inventory (BDI). A three-factor model of FSCRS (reassured-self, inadequate-self, and hated-self) showed the best-fitting measurement model in both samples. Measurement invariance of the test for clinical and non-clinical samples was also examined, and the findings support the measurement invariance of FSCRS scores across clinical and community sample. The dimensions of self-criticism had positive, and reassured-self had negative correlations with BDI and subscales of LOSC in both groups. Internal consistency was analyzed via Cronbach’s alpha coefficients. The Cronbach’s alpha coefficients for clinical and non-clinical sample were found to be .86 and .78 for inadequate-self, .85 and .74 for reassured-self, and .75 and .65 for hated-self respectively. Our results show that the FSCRS demonstrates good psychometric properties in clinical and non-clinical sample. The Turkish version of FSCRS can be used as a process and outcome scale for clinicians and researchers in clinical and non-clinical sample.
