Considerations & references
Reliability / validity:
Inter-rater reliability R = 0.9556+; Intra-rater reliability R = 0.8245+
Concurrent validity established by comparison w. BSID & PDMS
Structural validity established through studies of scale with ability to discriminate normal and abnormal
Strengths / weaknesses:
Easy to use, and see the child trajectory of development on graph
Very quick to complete, minimal equipment needed; observational
Highlights areas of “weakness” – effective for care planning and education of parents
Can be repeated monthly to demonstrate progress & effectiveness of input.
Less reliable in infants of very young age (>4 months) and infants approaching independent ambulation (after 12 months)
Not designed for use in infants developing atypically and should be used cautiously with this group.
Time to complete
20-30 minutes on initial assessment. Repeat tests may be quicker.
