Specific vs general cognitive remediation for executive functioning in schizophrenia: a multicenter randomized trial.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Rehabilitation

Background:

• Cognitive deficits are common in various neurological and psychiatric conditions.
• Cognitive remediation therapy (CRT) aims to improve cognitive functions.
• Individualized therapy approaches may offer tailored benefits over general programs.

Purpose of the Study:

• To compare the efficacy of an individualized therapy program (RECOS) against a general cognitive remediation therapy (CRT).
• To assess the impact of both therapies on cognitive functions and clinical measures.

Main Methods:

• 138 participants were randomized into either the RECOS group (n=73) or the CRT group (n=65).
• RECOS involved tailored training modules based on individual cognitive concerns (memory, attention, reasoning).
• Outcomes included the Behavioural Assessment of Dysexecutive Syndrome (BADS), cognitive tests, and clinical measures, assessed at baseline, post-therapy, and 6-month follow-up.

Main Results:

• No significant difference was observed in the main outcome (total BADS score) between RECOS and CRT.
• Both RECOS and CRT groups showed significant improvements in BADS profile scores and various cognitive functions (executive functions, attention, memory).
• Self-esteem improved in the RECOS group, while working memory improved in the CRT group, with no significant between-group differences in these specific changes.

Conclusions:

• The individualized RECOS program and the general CRT demonstrated comparable overall efficacy in this trial.
• Both cognitive remediation approaches yielded significant improvements in cognitive functions and executive behaviors.
• Further research may explore specific advantages of individualized versus general cognitive remediation for distinct patient populations.
