Background
Meta-analyses have reported that the effects of cognitive remediation might go beyond improvement in cognition to include unexpected benefits for schizophrenia patients such as negative symptom reduction and improvements in functioning. In addition, some evidence indicated that these potentially beneficial effects are also present in the initial course of schizophrenia, but work in this area is still developing.Method
A RCT compared Cognitive Remediation (CR) to Healthy Behaviors Training (HBT) in 80 patients (78% male) with a mean age of 21.9years and mean education of 12.3years who had a first psychotic episode within two years of study entry. Participants were trained using CR programs or received HBT involving 50 sessions over 6months and then booster sessions over the next 6months. The SANS and BPRS were used to assess symptoms. The UCLA Social Attainment Survey assessed social functioning.Results
Using GLMM, improvements over 12months were found favoring CR for SANS Expressive Symptoms (p<0.01), which was composed of Affective Flattening (p<0.01) and Alogia (p=0.04), and for SANS Experiential Symptoms, composed of Avolition/Apathy (p=0.04) and Anhedonia/Asociality (p<0.01). CR was associated with improvements in social functioning (p=0.05) as compared to HBT.Conclusions
We confirmed that the beneficial effects of CR appear to extend beyond cognition to improvements in negative symptoms and social functioning in early course schizophrenia patients. These results suggest that cognitive remediation might have an impact when the reduction of risk factors for chronicity is most critical for promoting recovery.Many UC-authored scholarly publications are freely available on this site because of the UC's open access policies.
