Successful evaluation of cognitive function and the nature of cognitive deficits among people with schizophrenia in clinical rehabilitation settings

Objectives:Despite possessing considerable relevance for planning and delivery of effective rehabilitation interventions, systematic evaluation of cognitive function is often ignored in clinical practice. This paper describes a successful method for measuring cognitive function and the nature of cognitive deficits (CD) in people with schizophrenia admitted to psychiatric rehabilitation services.Methods:Data on the cognitive functioning of consecutive patients with schizophrenia / schizoaffective disorder admitted during a 5-year period to a public in-patient rehabilitation facility was collated retrospectively and analysed. The Brief Assessment of Cognition in Schizophrenia (BACS) was used to evaluate cognitive function.Results:It was possible to administer the BACS to 122 of 135 consecutive admissions. The mean composite score on the BACS was 1.8 standard deviations below the norm, and 43% had moderate or severe CD. The BACS sub-tests of list learning and symbol coding revealed more severe deficits.Concl...
