The purpose of this study was to further examine the reliability of the Peabody Picture Vocabulary Test (PPVT), a new instrument to measure hearing vocabulary so that a student's verbal intelligence may be inferred. A group testing procedure was utilized by reproducing the PPVT plates on 35 millimeter transparent slides and projecting them onto a…

The report provides detailed information about the methods and instruments used to evaluate school readiness initiatives, discusses important considerations in selecting instruments, and provides resources and recommendations that may be helpful to those who are designing and implementing school readiness evaluations. Study results indicate that…

While the PPVT is widely used with both typical (i.e., regular classroom students) and atypical (i.e., special class students such as retardates or cerebral palsied) children, there is a dearth of reliability data available for the typical group. (Authors)

The use and validity of the Peabody Picture Vocabulary Test and the Slooson Intelligence Test as screening devices when compared to the Wechsler Intelligence Scale for Children was studied in 36 mentally retarded adolescents. (Author)

The purpose of this study was to determine whether a Mexican version of the Peabody Picture Vocabulary Test could be improved by directly translating both forms of the American test, then using decision procedures to select the better item of each pair. The reliability of the simple translations suffered. (Author/BW)

A study using the Peabody Picture Vocabulary Test (Revised) was conducted to determine whether the increase in reliability when both Forms L and M were employed justified the increase in time required for the longer procedure. Children in grades four, five, and six were involved in the project. (PP)

This report is a review of reliability data on the PPVT obtained from 32 research studies published between 1965 and 1974. For average children in the elementary grades, and for retarded people of all ages, PPVT scores remained relatively stable over time and there was close equivalence between alternate forms. (Author)

Summarizes state-of-the-art approaches for assessing visual stimulus same/different judgments in individuals with severe intellectual disabilities. Methodological investigations indicate that one can obtain reliable same/different judgments with a variety of stimuli in virtually anyone for whom a basal score on the Peabody Picture Vocabulary Test…

This study reports an attempt to improve the administration of the Peabody Picture Vocabulary Test (PPVT) by identifying and modifying aspects of the test which adversely affect disadvantaged preschoolers' performance. The resultant test was called the Modified Peabody Picture Vocabulary Test (M-PPVT). Two samples from the same lower class…

Investigated the relaionships among the Peabody Picture Vocabulary Test Revised (PPVT-R) alternate forms and the relationship of each PPVT-R form with the Wechsler Adult Intelligence Scale-Revised (WAIS-R). All correlations with both forms of the PPVT-R were significant. PPVT-R mean scores did underestimate significantly all WAIS-R mean scores.…

Explored the relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Peabody Individual Achievement Test (PIAT) administered to a sample of 29 mentally retarded children. Findings indicated that the PPVT-R predicted achievement as measured by the PIAT only moderately; and that PPVT-R scores correlated with achievement…

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)
