Abstract : Insight is a challenging concept, and it is difficult to give it a clear definition that is acceptable for all experts and theorists [1]. Cognitive insight usually is an awareness of a kind of self-reflective (unusual) and self-certainty judgment in a patient which has been considered by clinical scientists of mental illnesses and improvement of mental health [2,3]. There are assessments of repeatedly ineffective thoughts among schizophrenia patients which have impeded cognitive insight and cognitive insufficiency among these patients is deeper than normal people[4], Also the intensity of cognitive and meta-cognitive lacks among schizophrenia patients are more than other psychotic groups like; psycho affective, mood disorder and anxiety disorder[5- 7,9,11,35,36]. Which means that weakness of insight also has relation with patients other than schizophrenia ones, but among schizophrenia patients it is more intense [10], It is in a way that has an inverse relation with positive symptoms of schizophrenia. Interference in the therapy process of those patients who don't have insight of the symptoms and syndromes of their illnesses comes across with difficulties, because self-awareness and insight have positive effects on the illness [9].
