The assessment of chosen psychometric features of B-CATS test battery in schizophrenia – preliminary report
The assessment of cognitive impairment in schizophrenia proves helpful in the diagnosis of disease, identification of individuals at risk for adverse outcome and choosing the most adequate treatment. It is also a valuable complement of the psychiatric diagnosis. For this reason, there is a great need for a practical well-validated instrument to measure cognitive deficits that can be administered and interpreted easily in a clinical setting. The aim of the study was to verify the reliability, validity and practicality of the Brief Cognitive Assessment Tool for Schizophrenia (B-CATS) in a clinical setting.
68 psychotic patients were included in the study during their stay in a psychiatric ward. A double measurement was conducted. Test-retest assessment included tests of B-CATS battery (TMT part B, Category Fluency, Digit Symbol Test). To evaluate the intensity of psychopathological symptoms the PANSS was performed. SLOF, GAF, GARF, SOFAS were used to assess functioning of the subjects.
The B-CATS is characterized by a satisfactory relative stability. The absolute stability should be seen as sufficient in case of one test: Fluency. The diagnostic validity of the battery is satisfactory. B-CATS is easy to administer and "friendly" for the patient.
B-CATS is a brief and practical instrument that can provide clinicians with meaningful data regarding the global cognitive functioning of the psychotic subjects.
