Abstract Work and social functioning in schizophrenia are strongly influenced by
cognitive impairment so improving cognition is a priority in the treatment of schizo-
phrenia. Until recently the lack of a widely accepted index of cognitive change for use in
schizophrenia was a major obstacle to the development of cognition enhancing treatments.
The MATRICS (measurement and treatment research to improve cognition in schizo-
phrenia) consensus cognitive battery (MCCB) was developed as a standard cognitive
battery for use in clinical trials of cognition enhancing treatments for schizophrenia and has
attracted worldwide interest. To analyze the reliability and validity of a translated and
adapted Polish approved academic version of the MCCB. Sixty one patients were assessed
at baseline and again after 30 days. The study protocol approximated the MATRICS
psychometric and standardization study; the 10 tests that comprise the MCCB were
administered to participants. Functioning and psychopathological symptoms were also
assessed. Patients and test administrators also assessed the tolerability and practicality of
all the cognitive tests. All tests in the battery were found to have high test-retest reliability.
All the tests were rated as tolerable and practical by patients and administrators. However
practice effects were generally higher in the Polish version of the MCCB than in the
original version. Our analysis corroborates previous evidence that the MCCB represents a
good tool for assessing cognitive deficits in research studies of schizophrenia also in non-
English speaking countries.
