title: Knowledge in schizophrenia: The Portuguese version of KAST (Knowledge About Schizophrenia Test) and analysis of social-demographic and clinical factors' influence.
abstract: Schizophrenia is a complex disorder, and the knowledge about it can have a positive impact. The purpose of this study was to make the translation and cultural adaptation of the Knowledge About Schizophrenia Test (KAST) into Portuguese and determine the influence of clinical and socio-demographic factors on knowledge. The test was applied to 189 caregivers of patients enrolled in Schizophrenia Program of the Federal University of São Paulo, 30 caregivers of clinical patients of the General Outpatient Clinic of the same University, and 30 health professionals. The face and content validity of the test was established. The mean value (SD) obtained with the application of the final version to caregivers of schizophrenic patients was 12.96 (2.45) - maximum 17. Level of knowledge increased considering the following order: caregivers of clinical patients, caregivers of patients with schizophrenia and mental health professionals. The intraclass correlation coefficient (0.592) obtained in the test-retest was statistically significant. An influence of social class, race, gender and education of the caregiver on the test was observed, and the last two factors were more relevant. The KAST translated and adapted into Portuguese is a valid instrument and can be used as an evaluation tool on psychoeducational interventions.
