Examining the Utility of the New Raney Vocabulary Measure Alongside the WAIS-III

Abstract

Psychometric tests related to vocabulary assessments are, for the most part, restricted in their use by trained professionals and/or are costly. These restrictions limit their use, especially for research purposes. To circumvent these limitations, the Raney Vocabulary Measure was created for assessing vocabulary proficiency, specifically for research purposes. The measure consists of 30 questions where participants were instructed to choose the best definition of each word. The purpose of the study was to examine the utility of the new measure using the highly standardized but protected Wechsler Adult Intelligence Scale. Results from the linear combination of the subscales revealed the significant prediction of the Raney Vocabulary Measure, with the Vocabulary subtest contributing most to the unique variance. These results support that the test examines vocabulary ability. The current results are promising as the test would allow for greater accessibility for researchers who do not have access to restricted psychometric tests.
