- Conditions
- Schizophrenia
- Registration Number
- NCT00295048
- Lead Sponsor
- University of Maryland, Baltimore
- Brief Summary
The purpose of this study is to evaluate the efficacy of an innovative, computer driven cognitive rehabilitation program for individuals with schizophrenia and related disorders.
- Detailed Description
Schizophrenia is associated with neurocognitive impairment, diminished life satisfaction, lack of independence, and poor functioning in social, occupational and other desired and expected community roles. The personal, social and economic costs of this illness are enormous. Neurocognitive deficits (e.g., slowed thinking, poor attention and memory, inadequate problem solving) are now recognized as core features of the illness, and primary contributors to functional impairment among patients (Bellack, Gold \& Buchanan; 1999; Green, 1996). While standard antipsychotic medications improve psychotic symptomatology in many patients, their impact on neurocognition is modest, at best, and dramatic functional deficits remain even after adequate pharmacological treatment (Keefe et al., 1999). Hence, there is growing interest in alternative treatment strategies to address cognitive deficits, including computer-assisted cognitive remediation.
The purpose of this project is to assess the efficacy of a computer-assisted cognitive remediation program we have developed: Computer Assisted Cognitive Remediation (CACR). Fifty individuals with schizophrenia and related disorders will be recruited and randomly assigned to one of two conditions: a) 36 sessions of CACR; or b) 36 sessions of a manualized computer control condition (RC). The efficacy of CACR will be assessed on behavioral performance in three dimensions: (1) on the trained learning exercises, (2) on neuropsychological measures, and (3) on role play based assessments of everyday problem solving. We hypothesize that CACR will be more effective than the control treatment in each domain.
