Objective: Social cognition deficits are well known in schizophrenia patients. This study aims to conduct the validity and reliability study of the Turkish adaptation of the Situational Feature Recognition Test-2 (SFRT-2), which was developed to assess social knowledge, an area of social cognition, in schizophrenia patients. Method: In the study, 100 schizophrenia patients and 60 healthy controls were administered the Reading the Mind in the Eyes Test, the Hinting Task, the Facial Emotion Identification Test, the Facial Emotion Discrimination Test and the SFRT-2. The reliability of the test was analyzed with Intraclass Correlation Coefficient (ICC) and Bland-Altman plots by performing a retest two days later in 16 patients. Divergent validity was examined between the composite scores of the test and other social cognition test scores using the Spearman correlation coefficient. Known-groups validity was evaluated with the Mann-Whitney U test, while discriminant validity was examined using ROC analysis. Results: In the test-retest reliability analyses, the correlations between the pre-test and post-test scores were found to be good and significant for all sub-scores and composite scores (ICC=lowest 0.833-highest 0.941), except for SFRT5 (ICC=0.634). In the divergent validity analyses, positive correlations were found between SFRT-2 hits scores and the Reading the Mind in the Eyes Test (r(s )= 0.338, p<0.001), the Hinting Task (r(s )= 0.225, p=0.001), and the Facial Emotion Identification Test scores (r(s )= 0.270, p<0.001). In contrast, negative correlations were found between SFRT-2 false positive scores and the Reading the Mind in the Eyes Test (r(s )= -0.157, p=0.026) and the Hinting Task scores (r(s )= -0.194, p=0.006). In ROC analysis, the area under the curve was 0.744 (95% CI 0.665-0.823, p<0.001) with 81.0% sensitivity and 61.67% specificity. Conclusion: The Turkish adaptation of the SFRT-2 has been shown to be a reliable and valid instrument for assessing social knowledge deficits in schizophrenia patients.
