title: The relationship between insight, illness and treatment outcome in schizophrenia.
abstract: Lack of awareness of mental disorder in schizophrenia has been increasingly identified by researchers during recent years due to a resurgence of interest in the subject. In addition, better measurement methods have led to more valid and detailed investigations on insight in schizophrenia. Poor insight has been reported as a common phenomenon which may have both nosological and prognostic value. Specifically, due to recent studies indicating that lack of insight in schizophrenia may lead to poor treatment outcome, research focused on this phenomenon could lead to increasingly effective and efficient treatment strategies. However, many past and present studies reporting a correlation between insight and outcome in schizophrenia demonstrate significant theoretical or methodological limitations which may limit the implications and generalization of findings. This article lists and critically analyzes historical and contemporary research focusing on insight, illness, and outcome in schizophrenia. The role of insight is outlined, as are current methods for assessing awareness of mental disorder in schizophrenia. Cumulative research in this area is then reviewed, in terms of hypotheses, methods, conclusions, and limitations. Finally, suggestions for future research in this area are delineated.
