Effectiveness of attention training in schizophrenia.
This study assessed the impact of attention training on information processing in schizophrenia. Fifty-four inpatients with chronic schizophrenia were randomly assigned to two groups after baseline assessment with the Continuous Performance Test (CPT). Patients in the experimental group participated in individual sessions of computerized attention remediation, while patients in the control group participated in individual sessions during which they viewed video documentaries. After 18 sessions, reassessment with the CPT showed that patients in the experimental group had made significantly more improvement than the control group, which made no significant change. Brief Psychiatric Rating Scale assessments before and after the study phase indicated that both groups improved on the total score but the experimental group made significantly more improvement. These results suggest that it is feasible to use practice and behavioral learning to remediate a core attention deficit in chronic schizophrenia.
