The relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the McCarthy Screening Test (MST) was investigated with a sample of 39 Caucasian children from a semirural, Northeastern Ohio school district. The sample consisted of 23 males and 16 females, whose mean age was 62.3 months. Pearson product moment correlations were obtained between the measures, and correlated f-tests were completed. All of the subtests of the MST, excluding Numerical Memory and Leg Coordination, correlated positively and significantly with the PPVT-R. Discussion regarding the relationship found between the MST and the PPVT-R and that previously found between the McCarthy Scales of Children's Abilities (MSCA) and the PPVT-R is presented.
The Peabody Picture Vocabulary Test (PPVT) (Dunn, 1959) has been widely used in educational, clinical, and research settings, due in part to its ease of administration and scoring, and to the minimal amount of verbalization required between examiner and examinee. These characteristics, coupled with a more refined, representative standardization sample, are found in the Peabody Picture Vocabulary Test-Revised (PPVT-R) (Dunn & Dunn, 1981), which will most likely lead to a high level of popularity for the Numerous studies concerning the PPVT have been conducted in an attempt to determine the comparability of scores obtained on a variety of diagnostic tests. Hodapp and Hodapp (1980), Vance, Pritchard, and Wallbrown (1978), and Covin (1977) have demonstrated that the PPVT overestimates the intellectual ability of students designated EMR by approximately 6 to 10 IQ points, as measured by the Wechsler Intelligence Scale for Children-Revised (WISC-R) (Wechsler, 1974).
Prasse and Bracken (1981) compared the PPVT-R and WISC-R scores of 61 students classified as EMR. Significant differences were displayed between the PPVT-R mean standard score and higher WISC-R Verbal, Performance, and Full Scale scores. These results suggest that, rather than exceeding an EMR student's general mental ability, the measure of receptive vocabulary obtained through the PPVT-R underestimates the intellectual ability of such children by approximately 5 points. Naglieri (1981) has investigated the relationship among the PPVT-R, the Peabody Individual Achievement Test (PIAT) (Dunn & Markwardt, *1970), and the McCarthy Scales of Children's Abilities (MSCA) (McCarthy, 1972) for 26 primary elementaryaged children. The findings of Naglieri indicated that the PPVT-R correlated positively and significantly with the Verbal, Quantitative, Memory, and General Cognitive Indices of the McCarthy Scale (median r=.76). Mean scores of the PPVT-R and the General Cognitive Index of the MSCA were almost identical (104.5 and 104.4,respectively). However, Naglieri emphasized that the PPVT-R should not be considered interchangeable with the General Cognitive Index of the MSCA. Both Naglieri (1981) and PPVT-R.
