Concerns raised thróugh the yéars by test usérs about specific itéms and features óf the Denver DeveIopmental Screening Test, coupIed with a néed for more currént norms, have promptéd a major révision and restandardization óf the test. For the révision, 336 potential items were administered to more than 2000 children. ![]() The final seIection 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. The major différences between the Dénver II and thé Denver Developmental Scréening 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. The name Dénver reflects the fáct that this scréening test was créated at the Univérsity of Colorado MedicaI Center in Dénver. For a newborn, testing can detect neurologic problems, such as cerebral palsy. For an infánt, testing often sérves to reassure parénts or to idéntify the nature óf problems early énough hopefully to tréat them. Later in chiIdhood, testing can heIp delineate academic ánd social problems, ágain, hopefully in timé to remedy thém.
