Insight and social cognition dysfunction in schizophrenia: a review of the literature
Keywords:
Insight, Social cognition, theory of mind, insight, schizophreniaAbstract
Impairment in insight has significant short- and long-term clinical implications for adherence to treatment and psychosocial func-tioning. It is acknowledged that insight should be considered as a multi-dimensional construct, and research on factors specifically related to poor insight may be of crucial importance in understanding dysfunction of psychosocial functioning as well as in developing more effective intervention strategies in the future. The focus of resent research has been on social cognition deficits as a potential factor affecting insight. The purpose of this paper is to present current concepts regarding lack of insight in schizophrenia and research findings linking these concepts to disturbances in social cognition. Inconsistencies in published to date study results may be partly due to various methods used to assess social cognition and in-sight. The studies showing a relationship between the two variables have emphasized a correlation between disturbances in so-called second-order theory of mind and impaired insight. Additionally, poor performance in Theory of Mind tests using indirect instructions have more frequently been associated with lack of insight. Only further research on the discussed relationship that will include the individual dimensions of insight may confirm the hypo-thesis that deficits in social cognition are predictive of impaired insight in subjects with schizophrenia.
