Background:

Computerized cognitive remediation (CCR) shows promise for improving executive function in schizophrenia.
Previous studies reported inconsistent effects of CCR on verbal memory in schizophrenia patients.

Purpose of the Study:

To investigate the effects of a 3-week computerized cognitive training program on neurocognitive functions in schizophrenia patients.
To determine if cognitive remediation extends beyond executive function improvements.

Main Methods:

42 inpatients with schizophrenia were randomized into a CCR group or a treatment-as-usual (TAU) control group.
The CCR group received 15 sessions of computerized cognitive training (Cogpack) over 3 weeks.
Neurocognitive functions were assessed pre- and post-intervention.

Main Results:

The CCR group demonstrated significant improvements in verbal learning, processing speed, and executive function (verbal fluency) compared to the TAU group.
These findings suggest that cognitive remediation can enhance multiple cognitive domains.

Conclusions:

Computerized cognitive remediation is effective in improving executive function, processing speed, and verbal learning in schizophrenia.
Cognitive remediation may offer broader cognitive benefits than previously established for schizophrenia treatment.
