The Peabody Picture Vocabulary Test: What Does it Measure?

Abstract

There has been some question as to what the Peabody Picture Vocabulary Test measures. Although research indicates it has inadequate validity as a test of intelligence, other studies indicate it is an adequate measure of language ability. The present study correlated and factor analyzed the results from the Peabody test with results from a measure of linguistic and intellectual functioning. The analysis indicates that the test is not an adequate measure of either linguistic or intellectual abilities.
