Abstract:
The purpose of this preliminary investigation was to assess the equivalence of Forms L and M of the Peabody Picture Vocabulary Test--Revised for a sample of 15 Hispanic and 12 black children diagnosed as having Acquired Immune Deficiency Syndrome (AIDS). The children (15 boys, 12 girls) were administered PPVT-R Forms L and M in counterbalanced order and in immediate succession. The coefficient of equivalence, r, was .77 and significant. Influential factors, such as the behavioral manifestations of AIDS, are discussed. Limitations of the study are included. Research should focus on the long- and short-term stability of the test for these children as they are evaluated repetitively.
