The present study compared three commonly used cognitive screeners: the Test of Cognitive Skills – Second Edition (TCS-2), the Kaufman Brief Intelligence Test (K-BIT), the Wide Range Achievement Test – Third editions (WRAT3) and the impact of marijuana use on these screeners in a population of juvenile delinquents. One hundred records (67 males and 33 females) were selected from archival data at the Allen County Juvenile Center. Results from this study found, that as predicted, individuals who tested positive for marijuana performed significantly worse on all subtests of the TCS-2, on the Verbal and Composite Score of the K-BIT, and the Spelling subtest of the WRAT3 than individuals who tested negative for marijuana use. The results of this study support the notion that marijuana can impair cognitive abilities in a group of adolescents. / Department of Psychological Science
