Objectives: The present study is focused on further validation procedure of the CSSS - short screening scale designed for fast detection of persons with cognitive impairment and coexisting psychosocial disorders that demand deeper neuropsychological diagnosis and rehabilitation.

Methods: 67 subjects with schizophrenia and 36 healthy controls were examined with the CSSS, BACS, PANSS, and the Global Assessment of Functioning (GAF). Relationships between the CSSS score, age and education were tested with simple linear regression in groups of 124 subjects with schizophrenia and 36 healthy controls.

Results: Numerous statistically significant (p< 0.05) relationships between the CSSS and the BACS subtests, and the CSSS and the PANSS subscales were observed. The corrected CSSS score differs GAF ? 70 group from GAF >70 group.

Conclusions: The CSSS is a short method with satisfactory validity, that is adequate to the assumed goals and might be promising with respect to further development.
