Abstract

Some have argued that the Wonderlic Personnel Test (WPT) may represent a brief and efficient measure of intellectual functioning (e.g., Dodrill, 1980). The present study investigated the validity of the WPT as such a measure, in individuals with head injury. The findings suggested that, although the WPT showed relatively high agreement with the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in the whole group, it did not have good agreement with WAIS-R scores on an individual case basis. Since clinical practice typically seeks to evaluate individual performance, it is suggested that the WPT is not a suitable tool for psychological assessment of individuals with known or suspected head injury.
