Psychopathologic, neuropsychological and functional outcome measures during cognitive rehabilitation in schizophrenia: a prospective controlled study in a real-world setting.
BACKGROUND
Cognitive dysfunction has been demonstrated in patients with schizophrenia, and this may affect patients' functional outcome. The improvement of such dysfunction by means of cognitive remediation interventions has become a relevant target in the care of schizophrenia.


OBJECTIVE
To assess the effectiveness of the cognitive subprograms of Integrated Psychological Therapy (IPT) on symptomatological, neuropsychological and functional outcome variables and to analyze the relationships between cognitive and functional outcome changes in schizophrenia.


METHODS
Thirty-two patients with schizophrenia were assigned to cognitive remediation (IPT-cog) or usual rehabilitative interventions in a naturalistic setting of care. Clinical, neuropsychological and functional outcome variables were assessed at baseline and after 24 weeks of treatment.


RESULTS
The IPT-cog group improved significantly more than the comparison group with respect to psychopathological and functional outcome variables. Moreover, only the IPT-cog group improved significantly in the neuropsychological domains of verbal and working memory, with specific significant correlations between neurocognitive performance and functional outcome changes.


CONCLUSIONS
The results of the study confirm the effectiveness of the cognitive remediation component of IPT in schizophrenia, and indicate that some of the changes in functional outcome may be mediated by improvement in specific cognitive domains.
