The major differences between the Denver II and the Denver Developmental Screening Test are: 1) an 86% increase in language items 2) two articulation items 3) a new age scale 4) a new category of item interpretation to identify milder delays 6) a behavior rating scale and 7) new training materials. To facilitate periodic developmental screening of all children, a Prescreening Developmental Questionnaire (PDQ) was created to identify those children who require a more thorough screening with the Denver Developmental Screening Test (DDST). The final selection of the 125 Denver II items was based on the following criteria: ease of administration and scoring, item appeal to child and examiner, item test-retest and inter-rater reliability, minimal 'refusal' scores, minimal 'no opportunity' scores, minimal subgroup differences, and a smooth step-like progression of ages at which 90% of children could perform the tasks.

Using regression analysis, composite norms for the total sample and norms for subgroups (based on gender, ethnicity, maternal education, and place of residence), were used to determine new age norms. The average number of times each item was administered was 540. For the revision, 336 potential items were administered to more than 2000 children. Concerns raised through the years by test users about specific items and features of the Denver Developmental Screening Test, coupled with a need for more current norms, have prompted a major revision and restandardization of the test. The Denver II is not a suitable screening test for use in South African infants, and further research is required.Since the Denver Developmental Screening Test was first published 23 years ago, it has been utilized worldwide and restandardized in more than a dozen countries. There is a slight to moderate agreement between the Denver II and the BSID III tests. The Denver II is not accurate in identifying developmental delay. The agreement between the results of the two tests were represented by a Kappa value of 0.111 for the BSID III assessed as “at risk” (p = 0.014), and 0.423 for the BSID III assessed as “handicapped” (p < 0.000). The Denver II had a specificity greater than 90%.for both BSID III composite cutoff values. 8% and 44.0% for a 14 BSID III composite score cutoff of <85 (“at risk”), and <70 (“handicapped”) respectively. The sensitivity of the Denver II in identifying developmental delay was. The results of infants that had both a Denver II and a BSID III were assessed. The study population consisted of both normal and high 10 risk neonates born between 1 July 2013 and 31 December 2015. This is a retrospective descriptive study. The Bayley Scales of Infant and Toddler Development III (BSID III) is used as a gold standard test, to determine the level of agreement between the two tests. This article aims at assessing the accuracy of the Denver II in identifying developmental delay 6 in high risk newborns. The Denver Developmental Screening Test II (Denver II) is used to assess the development of high risk newborns at a tertiary hospital in Johannesburg.
