Prior to 2000, the child viewed the images on the PPVT easel. After 2000, the Spanish version of the PPVT-R was no longer administered. For this reason, post-1986 assessment results may be less culturally biased than the 1986 version. In 1986, the PPVT assessment was administered only in English. A Spanish version of the PPVT-R, the Test de Vocabulario en Imagenes Peabody or "TVIP," was introduced into the child survey in 1988 and used through the 2000 survey round for a small number of children who preferred to answer the Spanish version. PPVT-R items are numbered in order of increasing difficulty. There are two parallel forms of the PPVT-R Form "L" has been used by the NLSY79 Child at all assessment rounds. Readers who wish to examine more than a single example of the actual images (or "plates") presented to the child, should access the PPVT-R Manual and materials (Dunn and Dunn, 1981) or contact NLS User Services. There are also 5 training words and image plates. Each image plate contains 4 black-and-white drawings, one of which best represents the meaning of the corresponding stimulus word. The PPVT-R consists of 175 stimulus words and 175 corresponding image plates. The last survey round to include the PPVT-R was 2014. The PPVT-R has been administered, with some exceptions, to NLSY79 children between the ages of 3-18 years of age until 1994, when children 15 and older moved into the Young Adult survey. Variations in the patterns of administration are somewhat complex for this assessment so the user is encouraged to examine Table 4 in the Child Assessments-Introduction section in order to understand which samples of children took this test over the various survey years. The child listens to a word uttered by the interviewer and then selects one of four pictures that best describes the word's meaning. The English language version of the PPVT-R consists of 175 vocabulary items of generally increasing difficulty.
The PPVT-R was designed for use with individuals aged 2½ to 40 years. The Peabody Picture Vocabulary Test, revised edition (PPVT-R) "measures an individual's receptive (hearing) vocabulary for Standard American English and provides, at the same time, a quick estimate of verbal ability or scholastic aptitude" (Dunn and Dunn, 1981).
