Understanding Sensitivity in Screening Tests

Play an AI-generated podcast conversation about this lesson

What does it mean if a screening tool has low sensitivity?

It correctly identifies all children who require further evaluation
It does not impact the identification of children needing further evaluation
It fails to identify children who require further evaluation (correct)
It overidentifies children who do not require further evaluation

What is the consequence of underidentification in a screening test?

Increased referrals for further evaluation
Higher sensitivity
Missed opportunities for early intervention (correct)
Reduced false positives

If a screening tool has low specificity, what is likely to happen?

There will be no false negatives
The tool will accurately identify all children who don't need further evaluation
Fewer children will be referred for further evaluation than necessary
More children will be referred for further evaluation than necessary (correct)
