Cognitive Screening Scale for Schizophrenia (CSSS): diagnostic efficacy in group of subjects with special rehabilitational needs
Abstract
Introduction: The aim of the presented paper is to examine the CSSS scale in terms of criterion validity of the adjusted
score, in relation to various rehabilitationally important aspects of Patients’ functioning.
Material and methods: In the three stages of the study, a total of N = 199 subjects with schizophrenia were examined.
In the first stage of the study N = 89 people were divided into groups: better (HF, high functioning) and worse
(LF, low functioning) functioning and differences were examined between these subgroups. In the second part of the
study N = 60 people were examined, where the relationship between the CSS score and the employment status was
analyzed. In the third stage of the study, N = 50 people were examined, among whom the relationships of the adjusted
score with the subjective assessment of cognitive functions were analyzed.
Results: The HF and LF groups significantly (U Mann-Whitney < 0.001) differed in terms of the CSSS-adjusted score.
The adjusted result 15 points with sensitivity of 81% and specificity of 60% differentiated the mentioned groups. The
adjusted score significantly differentiated people differing in the employment status, with the result of ca. 16 points
and higher, best characterized persons who were employed. There were no statistically significant relationship shown
between the adjusted score with subjective assessment of cognitive functions.
Conclusions: The CSSS adjusted score shows numerous connections with the functioning of Patients, giving hope for
high utility in detecting people with special rehabilitation needs.
