Overview
Brief Summary
The purpose of this study is to determine whether computer-assisted cognitive remediation therapy is effective in the treatment of cognitive deficits in schizophrenia.
Detailed Description
Schizophrenia can be considered a chronic illness that affects all aspects of daily life. Cognitive deficits seems to play a key role that interferes directly in the functional adaptation. Cognitive remediation therapy (CRT) emerges as a psychological intervention that target cognitive impairment. But, the use of computerized or papel an pencil procedures for remediation cognitive deficits remains controversial. Nonetheless, computer tasks offer a number of advantages compared to those of paper and pencil. The most noteworthy advantages are to enhance patient's motivation just because the sensory variety that the exercises presented or the possibility to provide immediate feedback. Furthermore, the possibility to present custom-tailored and adapted tasks taking into accounts the patients deficits and their evolution in the process of the psychological therapy is another important feature of computer-assisted cognitive remediation therapy.
