Evaluation of intelligence in youthful offenders: the Kahn Intelligence Tests.

It was hypothesized that there is a correlation between IQs on the Kahn Intelligence Tests and the WAIS. It was predicted that the correlation between the KIT IQs and the WAIS Performance IQs would be significantly higher than those between the KIT IQs and WAIS Verbal and Full Scale IQs. The KIT and WAIS were administered to 30 Negro and 20 white offenders ages 16-0 to 20-11. Pearson rs of .656, .649, and .714 were significant. Contrary to prediction, the r between the KIT IQs and the WAIS Performance was the lowest. Mean IQs were significantly different.
