Description

A researcher-administered, norm-referenced picture-based assessment developed by Dunn and Dunn for measuring receptive vocabulary in children and other examinees.

Components

• PPVT-III as an independent standardized measure of receptive vocabulary: The Peabody Picture Vocabulary Test (PPVT-III; Dunn & Dunn, 1997) served as the vocabulary outcome measure, administered by a researcher at child ages 30, 42, and 54 months. The authors chose it because "the PPVT is a widely used measure of vocabulary skill and, importantly, because it provides data that is independent from the parent-child interaction." This independence allowed the study to test whether caregiver input predicts vocabulary skill measured outside the interaction, avoiding contamination from concurrent caregiver speech. Raw scores were converted to age-appropriate standardized scores based on published norms. (Rowe Meredith L (2012))

Claims

• Input quantity at 18 months predicts child vocabulary at 30 months over and above SES and prior vocabulary skill [+M] (vocabulary measured with the PPVT-III)
• Parent vocabulary diversity at 30 months predicts child PPVT at 42 months with quantity, SES, and prior vocabulary controlled [+M]
• Parent rare word use at 30 months predicts child PPVT at 42 months with quantity, SES, and prior vocabulary controlled [+M]
• Parent narrative utterances at 42 months predict child PPVT at 54 months with quantity, SES, and prior vocabulary controlled [+M]
