Cognitive insight as an indicator of competence to consent to treatment in schizophrenia

The processes underlying the ability to make decisions about recommended treatments remain poorly understood in schizophrenia. The aim of this study was to explore the relationships between capacity to consent to medication and cognitive biases in 60 schizophrenia patients. Main measures included the MacArthur Competence Assessment tool for Treatment (MacCAT-T) and the Beck Cognitive Insight Scale (BCIS). After Bonferroni's correction for multiple correlations, the Self-Reflectiveness dimension of the BCIS was significantly associated with the dimension Reasoning of the MacCAT-T. Cognitive therapy, by enhancing patients' Self-Reflectiveness and considering alternative explanations, could lead to better capacity to consent to treatment in schizophrenia. (C) 2012 Elsevier B.V.
