2. Denver Developmental Screening Test: The Denver Developmental Screening Test (DDST) is a widely used assessment for examining children 0-6 years of age as to their developmental progress. The name 'Denver' reflects the fact that this screening test was created at the University of Colorado Medical Center in Denver.
3. Oct 15, 2011 Denver Developmental Screening Test II Aka: Denver Developmental Screening Test II, DDST-2.

The Denver Developmental Screening Test was first published in 1967. It has since been used on more than 50 million children worldwide.4 In 1990, it was revised to include more language items, two new articulation items, a new age scale, a new category of item.

Type of Measure: The DENVER II is a measure of developmental problems in young children. It was designed to assess child performance on various age-appropriate tasks and compares a given child’s performance to the performance of other children the same age. The instrument consists of 125 tasks, which broadly reflect the following areas: personal-social, fine motor-adaptive, language, and gross motor.

Target Population: Infants and pre-school age children (i.e. birth to six years of age)

Measurement properties and previous use: Four types of reliability were assessed (inter-rater, 5- to 10-minute test-retest, 7- to 10-day test-retest (same examiner and same observer), and 7- to 10-day test-retest (inter-examiner and inter-observer). The percent agreement rate for each of the four types of reliability was generally high with a few exceptions - both 7-10 day test-retest reliability assessments had mean percent agreement scores of less than 50%.

The validity of the the Denver II was established by the precision with which the ages corresponding to 25%, 50%, 75% and 90% passing for each item and subgroup had been determined. The authors indicate that the Denver II is face valid because of the manner in which it was standardized. The authors indicate that items were written and selected by professionals specializing in child development and pediatric screening.
