Schematic representation of a vocabulary construct defined by three versions in each of four tests. Vocab refers to WAIS Vocabulary, PVoc to Picture Vocabulary, Synvoc to synonym vocabulary, and Antvoc to antonym vocabulary. V1, V2, and V3 refer to different versions of tests with the same format but involving different items. Relations with ability constructs in the top panel are relevant to discriminant validity and relations of the vocabulary construct to the vocabulary test constructs, and of the test constructs to the test versions in the bottom panel are relevant to convergent validity.
