title: Self-perceived cognitive functioning does not correlate with objective measures of cognition in schizophrenia.
abstract: BACKGROUND
  Growing interest in the study of self-perceived cognitive deficits in schizophrenia has been recently observed. The authors validated in a previous study the Subjective Scale To Investigate Cognition into Schizophrenia Tunisian Arabic Version (SSTICS_tun_arab), a self-questionnaire established to collect cognitive complaints in patients with schizophrenia.
  
  
  OBJECTIVE
  The aim of the present study was to explore the relationship between the SSTICS_tun_arab scores and objective cognitive performances.
  
  
  METHODS
  One hundred four patients with schizophrenia spectrum disorders were administered measures of the Positive and Negative Syndrome Scale, the Global Assessment Functioning Scale, and the Calgary Depression Scale as well as measures of the SSTICS_tun_arab and a cognitive battery.
  
  
  RESULTS
  No correlations were found between objective neuropsychologic performances and scores of the SSTICS_tun_arab.
  
  
  CONCLUSIONS
  Our findings support the hypothesis of independence of self-perceived cognitive functioning from objective neuropsychologic deficits in schizophrenia. They also suggest that insight of mental illness seems to be not a unitary concept but more likely to be divided in different aspects including cognitive insight.
