Independent evaluation of Q‐Interactive: A paper equivalency comparison using the PPVT‐4 with preschoolers

Pearson now uses a technology‐based testing platform, Q‐Interactive, to administer tests previously available in paper versions. The same norms are used for both versions; Pearson's in‐house equivalency studies indicated that both versions are equated. The goal of the current study is to independently evaluate equivalency findings. For the current study, equivalency was measured using the three‐part test set forth by American Psychological Association in 1986. First, the researchers examined rank order similarity; then, they examined mean score similarity; and finally, they examined score‐distribution similarity. One of these equivalency standards (rank order similarity) was not met, and one other standard is debatable (mean score similarity); therefore, the authors noted concerns about the use of Peabody Picture Vocabulary Test, Fourth Edition Q‐Interactive for preschoolers. New normative data should be collected.
