چکیده انگلیسی
Whereas the efficacy of cognitive rehabilitation in schizophrenia is widely known, studies examining mechanisms for functional improvement are still scarce. The aim of the study was to examine the mediational mechanisms through which cognitive rehabilitation improves functioning in schizophrenia. One hundred and eleven schizophrenia patients were randomly assigned to either a 4-month cognitive rehabilitation group or an active control group. Patients underwent a neurocognitive battery (including processing speed, verbal memory, working memory and executive functioning) and social cognition assessment (emotion perception, theory of mind and social perception). Functioning was assessed by the combined use of a performance-based instrument, the UCSD Performance-based Skills Assessment (UPSA) and an observer-rated instrument, the Global Assessment of Functioning (GAF). The trial was registered in clinicaltrials.gov (NCT02796417). Multiple mediational analyses revealed that the effect of cognitive rehabilitation on functional improvement was partially mediated by changes in processing speed and verbal memory, but not by the domains of social cognition and negative symptoms. More specifically, verbal memory partially mediated the treatment's effect on performance-based functioning (UPSA), whereas processing speed acted as a partial mediator for observer-rated functioning (GAF). The effect of rehabilitation on functioning did not take place through all the domains that showed significant improvement. Verbal memory and processing speed emerged as the most crucial factors. However, these complex interactions need further research.
