Relationship between Executive Function and Cognitive Distortions on Delinquent Juveniles and Non-Delinquent Juveniles

The purpose of this ex-post facto research is study about relationship between executive function and cognitive distortion on delinquent juveniles and non-delinquent juveniles in Tehran. Statistical sample are 62 delinquent juveniles selected by purposeful selection from “the center of modification and training” and 82 people of non-delinquent juveniles selected by method of random sampling from students of middle and high school of Tehran. Irrational test of belief test (IBT) (jones, 1968) is used for studying cognitive distortion and gathering data about executive function used from the Coolidge personality and neuropsychological inventory test (CPNI). Statistical method include: independent t-test, correlation coefficient, one way analyze of variance and multi way analyze of variance. The results showed that the rate of executive function in delinquent juveniles is fewer than the juveniles that aren’t delinquent and also the rate of cognitive distortion in delinquent juveniles is more than non-delinquent juveniles. So there is no relation between executive function and cognitive distortion in the two groups. It seems that one of the determinative variables of delinquency causes the defect in executive function and cognitive distortion.
