The PDQ-II is a further revision of the PDQ and the R-PDQ which were based on the original and revised version of the Denver Developmental Screening Test (DDST), respectively. This version uses the norms (90th and 75th percentiles) from the DENVER II. The PDQ-II is a parent-answered prescreen consisting of 91 questions from the DENVER II, although only a subset of questions are asked for each age group. The form may need to be read to parents and caregivers who are less educated.
Four different forms are available and are selected based on age: orange (0 to 9 months), purple (9 to 24 months), cream (2 to 4 years), and white (4 to 6 years). The caregiver answers questions until (1) three "Nos" are circled (they do not have to be consecutive) or (2) all the questions on both sides of the form have been answered. Scoring is based on the number of delays or cautions as defined for the DENVER II.* Children who have no delays or cautions are considered to be developing normally. If a child has one delay or two cautions, the caregiver is provided with age-appropriate developmental activities to pursue with the child, and a rescreen with the PDQ-II is done one month later. If on rescreening, the child has one or more delays, the DENVER II is administered as soon as possible. If a child has two or more delays or three or more cautions on the first screening with the PDQ-II, the DENVER II is administered as soon as possible.
