Abstract: | The validity and reliability for the Peabody Picture Vocabulary Test (PPVT) was estimated with 52 nonpsychotic emotionally disturbed adolescents. Approximately 6 months after an initial administration of the PPVT and the Peabody Individual Achievement Test (PIAT), all children were retested. Significant increases in PPVT IQ and PIAT reading comprehension scores were found upon readministration. The internal consistency estimate for the initial PPVT administration showed considerable consistency in responding. A modest temporal stability estimate indicated a fair amount of fluctuation in scores over time. Concurrent validity coefficients for the PPVT indicated moderate to dependable relationships with PIAT subtests. Predictive validity estimates for the PPVT suggested moderate relationships with future achievement, accounting for some 26% of the variability in total achievement. |
