There is a broad range of evidence supporting the use of screening tests. While some instruments have been subjected to extensive scientific scrutiny, others have very little evidence to support their use. This guide, available for downloading at right, contains relevant psychometric characteristics of each developmental screening instrument as detailed in their test manual. This guide includes the following information:
- Sensitivity and specificity data for the specific ages recommended for screening by the AAP
- Whether the manual includes the following validity information:
- Sensitivity
- Specificity
- Positive predictive value
- ROC curve analysis
- Concurrent validity
- Predictive validity
- Factor analysis
