Table 5 Pearson correlations between standard battery domains and BACS measures

From: Cross-cultural adaptation and validation of the Arabic version of the BACS scale (the brief assessment of cognition in schizophrenia) among chronic schizophrenic inpatients

  1. Significant correlation at: *p < 0.05, **p < 0.01, ***p < 0.001.
  2. VM Verbal Memory; DS Digit Sequencing; TM Token Motor Task; VF Verbal Fluency; SC Symbol Coding; TL Tower of London.
  3. The correlation in patients with schizophrenia was controlled for duration of illness, duration of hospitalization and chlorpromazine equivalent dose
