A study of 1,300 adolescent boys found that the evidence was insufficient to establish a causal relationship between LD and JD, but that some type of relationship justifying further investigation did exist. A second study found that five intelligence/neurological performance predictors could significantly discriminate between delinquents and nondelinquents; a study of incarcerated delinquents found an LD incidence of 48.9 percent, as compared to a general population average of 5 to 10 percent. A study conducted by the American Institute for Research found that studies of the LD/JD relationship conducted prior to 1976 suffered from so many methodological problems, including an a prior assumption of the relationship, that they could not be used to provide even rough estimates of a possible link between LD and JD. Problems identified by other scholars include difficulties in definition and diagnosis, lack of and/or disagreements about an etiological basis for LD, and some findings of greater JD in non-LD populations. A number of authors have recommended the need for early identification and remediation of LD as appropriate for the affected JD population, and a study of instructional remediation for delinquents indicates that special education programming can reduce recidivism. While the LD/JD relationship remains unclear, it is recommended that efforts be made in the areas of public education and instructional remediation. Included are 19 references.
