Denver II Test Overview

Denver II Test Overview

• Widely used developmental screening test for children aged birth to six years.
• Identifies developmental delays, enabling early intervention.

Test Form Structure

• Comprises four developmental domains: Personal-Social, Fine Motor-Adaptive, Language, and Gross Motor.
• Each of the 125 items represented on a form indicates the age percentage at which children typically pass.

Testing Procedure

• Younger children tested while sitting on a parent’s lap; older children may use a chair.
• Present the testing process as a game to engage toddlers and preschoolers.

Parental Guidance

• Parents informed this is not an IQ test.
• Children are not required to pass all items; performance varies.

Cultural Considerations

• Southeast Asian and native African children may show delays in Personal-Social and Language development due to cultural differences.
• Protective parental attitudes can affect Self-Learning Skills, especially in Southeast Asian contexts.

Age Calculation Method

• Subtract date of birth from the testing date to determine age.
• Adjust for prematurity if necessary, using specific calculations.

Age Calculation Example

• Example: Test date 7/15/13, DOB 3/10/11 yields an age of 2 years, 4 months, and 5 days.

Adjusting for Prematurity

• Convert weeks of prematurity into months and days, using standard conversions.
• Subtract that duration from the child’s current age.

Drawing the Age Line

• Create an "age line" based on provided age scales.
• Use 1-month increments for ages up to 24 months and 3-month increments thereafter.

Testing Order Guidelines

• Start with items that parents can report on, followed by items not requiring verbal responses.
• Praise child's efforts during testing to encourage engagement.

Scoring Items

• Mark "P" for passed, "F" for failed, "N.O." for no opportunity, and "R" for refusal on the scoring sheet.

Item Administration Process

• Begin with three leftmost age-appropriate items; administer until three consecutive items are passed.
• Continue testing until three failures are recorded on the right side of the age line.

Behavior Rating

• Record child’s testing behavior and assess whether it aligns with typical behavior through parental input.

Identifying Delays

• Mark failures or refusals that lie entirely to the left of the age line by shading the bar's right end.

Caution Indicators

• Items where age lines cross at the 75th or 90th percentiles are marked with a large 'C' to indicate caution.

Results Interpretation

• Normal results: No delays and at most one caution; rescreen during the next well-child visit.
• Suspect results: More than one caution or one delay, with a follow-up rescreen in 1-2 weeks.
• Untestable results: Refusal in critical items; rescreen in 1-2 weeks.
