The DENVER II Developmental Screening Test
Test design
The test consists of up to 125 items, divided into four parts:

Social/personal: aspects of socialisation inside and outside the home - eg, smiling. Fine motor function: eye/hand co-ordination, and manipulation of small objects - eg, grasping and drawing. Language: production of sounds, and ability to recognise, understand and use language - eg, ability to combine words Gross motor functions: motor control, sitting, walking, jumping, and other movements What differentiates the DENVER II from other screening tests? It enables the tester to compare a child's development with that of over 2,000 children who were in the standardised population, like a growth curve. It consists of items in which a sub-sample (race, less educated parents, gender and place of residence), which varied a clinically significant amount from the composite sample, are identified and their norms provided in the DENVER II Technical Manual. It provides a broad variety of standardised items to give a quick overview of the child's development. It also contains a behaviour rating scale.

The test is primarily based upon an examiner's actual observation rather than parental report. PatientPlus o

No special training is required.
The test takes approximately 20 minutes to administer and interpret. There may be some variation in time taken, depending on both the age and co-operation of the child.

The items are recorded through direct observations of the child plus, for some points, the mother reports whether the child is capable of performing a given task. Younger infants can sit on their mother's lap.

The test should be given slowly.
Interpretation of the test
The data are presented as age norms, similar to a growth curve. Draw a vertical line at the child's chronological age on the charts; if the infant was...
