'The Denver Developmental Screening Test'. The measure was based on the Denver Developmental Screening Test but can be used with the Denver II. (Positive predictive value meant the probability that a child with a suspect Denver II would be diagnosed as abnormal when evaluated negative predictive value meant the probability that a child with a normal Denver II would be diagnosed as normal when evaluated.)Ī study of 3389 children under five in Brazil has produced a continuous measure of child development for population studies.
The authors concluded that in their program a suspect Denver II should usually result in referral. The authors concluded that a suspect Denver II “should lead to careful monitoring and rescreening unless provider or parental concern suggests the need for immediate referral.” Among children 18–72 months old, the prevalence of abnormality was 0.43 and the positive predictive value of the Denver II was 0.77, negative predictive value of 0.89, sensitivity 0.86, and specificity of 0.81. In children under 18 months the prevalence of abnormality was 0.19 on diagnostic tests, and the Denver II had a positive predictive value of 0.36, a negative predictive value of 0.90, a sensitivity of 0.67, and a specificity of 0.72. In a study of two-stage screening, children were prescreened with Frankenburg’s Revised Prescreening Developmental Questionnaire and 421 with suspect scores were given the Denver II and evaluated by independent examiners. The study showed the value of taking into account other information besides the test result because the screener increased the predictive value from 44% to 56% by using her judgment not to refer some children with minor delays. The predictive value was 56% allowing for children who were referred but not evaluated, it was 72% this compared favorably with two studies using the Ages and Stages Questionnaire in clinics, which found comparable predictive values of 50% and 38%. The success of the screening program was judged in terms of predictive value: the probability that a child, if referred, would be eligible for services. This study included 418 children in all and 64 who needed EI. Here the criterion for abnormality was the eligibility of children for Early Intervention, according to the judgment of speech-language pathologists and other professionals in two suburban school districts. As with all developmental testing, one must follow the instructions in detail.Īnother study evaluated the Denver II in the screening program of a community health center.

Videotapes and two manuals describe 14 hours of structured instruction and recommend testing a dozen children for practice.
The Denver II is available in English and Spanish. A normal score means no delay in any domain and no more than one caution a suspect score means one or more delays or two or more cautions a score of untestable means enough refused items that the score would be suspect if they had been delays. Items that can be completed by 75%-90% of children but are failed are called cautions those that can be completed by 90% of children but are failed are called delays. Each item is scored as pass, fail, or refused. An examiner administers the age-appropriate items to the child, although some can be passed by parental report. There are 125 items over the age range from birth to six years. The Denver Developmental Screening Test was revised in order to increase its detection of language delays, replace items found difficult to use, and address the other concerns listed.
