The purpose of this study was to compare PPVT-R age equivalents with language ages from the Test of Early Language Development - TELD 2 (Hresko, Reid, and Hammill, 1981) for a preschool population. This study sought to find the strength of association between the PPVT-R age equivalents and the TELD language ages. The subjects used in the study were 54 preschool children ranging in age from 3-6 through 4-7 years. Normal children were selected for the study based on their chronological age, sex, and socioeconomic status - SES.

"La traduction de toute méthode et de tout instrument de mesure développés par et pour un autre milieu culturel, doit être vérifiée afin d’éliminer l’erreur causée par la contamination des données de départ. La version de langue française des items 40 à 79 de la forme A du test de vocabulaire "P.P.V.T.” a été validée par une procédure multi-technigues. Après une technique de retraduction réalisée par deux groupes de traducteurs, une autre équipe de traducteurs a analysé les différentes versions obtenues pour choisir la meilleure traduction à chacun des items. Deux groupes de sujets anglophone et francophone ont passé ce test ou sa version et, après analyse de leurs résultats, leurs moyennes se sont avérées être comparables. La version en langue française de cette partie du *’P . P . V . T ., comparée au test original, est donc fidèle (selon le coefficient alpha de l’analyse de la fidélité) et valide (selon une analyse de la covariance)." / Québec Université Laval, Bibliothèque 2019

The purpose of this study was to obtain data from the PPVT-R scores of low and middle SES black kindergartners in the Portland area to determine if there is a difference between their scores and the scores reported in the PPVT-R. The primary question to be answered was do the scores of black kindergartners in Portland vary significantly dependent upon SES? The secondary questions this study sought to answer were: what are the means, standard deviations, and ranges of scores for black kindergartners in Portland and what are the means, standard deviations, and ranges for each two-month age group of black kindergartners in Portland?

The purpose of this study was to determine the relationship between the Peabody Picture Vocabulary Test-Revised, (PPVT-R) and receptive subtest of the Preschool Language Scale (PLS), and between the PPVT-R and the Test of Auditory Comprehension of Language-Revised (TACL-R), as well as determine how the tests compare in identifying children in need of further evaluation in the area of receptive language. The reasoning behind the goal of this study was to determine that if the three tests showed a strong, positive correlation and identified the same children as needing further assessment, then perhaps the test which was easier and shorter to administer (the PPVT-R) could be used with more confidence 2 as a quick, reliable screening tool of overall receptive language ability. In other words, if a child does poorly on the PPVT-R, one could assume that the child would most likely score below average on the other two tests also. Based on the results of this study, one cannot make this assumption.

The Model A and Model C Title I evaluation options were compared by using both options to measure the effectiveness of handicap intervention in a Head Start program. Two hundred three children in Jackson County (Oregon) were pretested with the Developmental Indicators of Learning Test (DIAL), the Peabody Picture Vocabulary Test (PPVT), the Visual-Motor Integration Scale (VMI), and the Carrow Elicited Language Inventory (CELI). The 43 children who scored below the predetermined cut-off level were placed in a six-month intervention program. One hundred forty-nine children remaining in the Head Start program in May were posttested with the same tests. Model A analysis of mean scores of the intervention group indicated significant score change on all three testing instruments. Model C analysis indicated no positive score change. It was posited that the Model A effect in this project was large because it combined a positive intervention effect with a positive general program effect. The Model C option showed no effect because the estimated nonintervention scores were very large due to the large positive score change in the nonintervention group.

The purpose of this investigation was to compare the results as recorded in mental ages of the PPVT and TACL when used with developmentally delayed children. One aspect was to observe how well the mean mental age from each test would compare with the mean mental age obtained from psychometric testing (WISC-R or SB-LM results). Another aspect was to determine how well the data from the PPVT and from the TACL would correlate with the psychometric testing results.
