Relationship of Fluid and Crystallized Intelligence with Cognitive Insight in Persons with Schizophrenia

Cognitive Insight addresses the evaluative and interpretative processes involved in anomalous experiences. Adegree of self-certainty in one's own abnormal thinking is associated with psychotic symptoms and indicates poor insight whereas self-reflection on one's thought processes involved in production of aberrant experiences leads to regulation and corrective experiences. In present study, we examined the role of fluid and crystallized intelligence in cognitive insight in persons with schizophrenia. 30 patients with schizophrenia were sampled from Institute of Mental Health and Hospital, Agra. Following tools were individually administered: (1) Beck Cognitive Insight Scale for measuring cognitive insight (2) Raven's Colored Progressive Matrices as a measure of fluid reasoning (3) Weschler Adult Performance Intelligence Scale-PR for fluid intelligence and (4) Verbal Adult Intelligence Scale of PGI Battery of Brain Dysfunction for Crystallized Intelligence (5) Vocabulary Sub-test of Binet-Kulshresth Test of Intelligence for crystallized intelligence. The correlational analysis revealed that self-reflectiveness dimension of cognitive insight is positively associated with both fluid and crystallized intelligence whereas self-certainty dimension does not have any significant relationship with either of the factors of intelligence.
