Profile Analysis of the Universal Nonverbal Intelligence Text Standardization Sample
Brian E. Wilhoit, R. Steve McCallum
Abstract.A normative typology was developed and applied using multivariate profile analysis of subtest scores of the Universal Nonverbal Intelligence Test (UNIT)standardization sample. Multistage cluster analyses were applied to the standardization sample for the UNIT Extended Battery, comprising all six subtests; and the UNIT Standard Battery, comprising four subtests. The results yielded a seven-profile cluster solution for the Extended Battery, and a six-profile cluster solution for the Standard Battery. Tight profile clusters that were separated extremely well from each other were produced. Demographic prevalence trends and replication rates of the resultant clusters are similar to other studies, but help to describe the cluster composition. Additionally, the results lend support to the UNIT’s underlying factor structure. Finally, user-friendly methods of determining whether clinical profiles are unique when compared to the profiles identified in the standardization sample are discussed.
