Design prerequisites for research on cognitive therapy for schizophrenia

Abstract

The results of various case studies, experiments, and quasi-experimental studies of cognitively oriented treatment interventions for schizophrenia are grounds for optimism. However, there are important methodological pitfalls that must be addressed if large-scale research is to confirm the efficacy of the cognitive approach. The pitfalls involve the heterogeneity of schizophrenia and its cognitive impairments, and the role of specific and nonspecific factors in psychosocial treatments. Special methodological and design strategies are required to address these complications. © 1992 Oxford University Press.
