Learning disabilities and delinquency: a study of Israeli prison inmates

Research consistently illustrates that several intellectual disabilities--namely, learning disabilities (LD), low intelligence, challenging behavior, and inadequate adaptive behavior, as well as attention deficit hyperactivity disorder (ADHD)--are considered risk factors for antisocial and criminal behavior. Although much attention has been paid to the relationship of LD, ADHD, and criminal behavior, three research topics have been overlooked: the frequency of LD with ADHD among inmates, the relationship between LD and/or ADHD and level of education among prisoners, and the connection between LD and/or ADHD and age of criminal onset. The present study examined the frequency of LD and ADHD in a sample of Israeli-born prisoners, in addition to the frequency of each category by itself, and it investigated the relationship of LD and/or ADHD, school dropout age, and onset of criminal activity.
