Spanish adaptation and validation of the situational feature recognition test 2 (SFRT-2) in patients with schizophrenia and healthy controls.

The main purpose of the present study was to adapt and validate the social perception measure "Situational Feature Recognition Test 2″ (SFRT-2) in Spanish psychiatric and non-psychiatric population. One hundred and one patients with schizophrenia and 100 healthy controls (HC) were assessed. Test's reliability was studied by Cronbach's alpha coefficients. Concurrent validity was assessed using Spearman's correlations. Discriminant validity was studied by comparing schizophrenia and HC groups by means of the ROC curve analysis. Internal consistency indexes of the test ranged from alpha = 0.66 to alpha = 0.90 in both groups. The SFRT-2 scores correlated with scores obtained in other social cognition measures such as Theory of Mind. The ROC curve analysis showed that the composite score including both actions and goals scores of the SFRT-2 discriminate well between patients and HC (AUC = 0.81). The Spanish adaptation and validation of the SFRT-2 showed good psychometric properties in both patients with schizophrenia and HC. To our knowledge, this is the first adaptation and validation of an existing social perception measure in native Spanish-speaking patients with schizophrenia. Results further support the use of the SFRT-2 as social perception measure in clinical practice and research.
