Abstract

Objectives:It was reported that patients with schizophrenia showed subjective complaints about the cognitive dysfunction as well as neuro-cognitive impairments. The aim of this study was to examine the association between the subjective complaints of the cognitive dysfunction and the objective assessments of neuro-cognitive function in patients with schizophrenia.
Methods:Twenty-three patients with schizophrenia and 32 normal controls were recruited. Neuro-cognitive domains of verbal memory, visual memory, attention and working memory, and executive function were measured by neuro-cognitive test batteries. The subjective complaints of cognitive dysfunction were measured by using the Frankfurt Complaints Questionnaires (FCQ), a self-report scale.
Results:There was no significant correlation between subjective cognitive complaints and objective neuro-cognitive impairments, though patients with schizophrenia showed neuro-cognitive impairments across all domains and increased subjective cognitive complaints.
Conclusion:These findings did not support the association between subjective cognitive complaints and objective neuro-cognitive impairments in patients with schizophrenia. (Korean J Schizophr Res 2010;13:20-27)
