Concurrent Validity of the Harris Infant Neuromotor Test and the Alberta Infant Motor Scale

We examined concurrent validity of scores for two infant motor screening tools, the Harris Infant Neuromotor Test (HINT) and the Alberta Infant Motor Scale, in 121 Canadian infants. Relationships between the two tests for the overall sample were as follows: r = -.83 at 4 to 6.5 months (n = 121; p < .01) and r = -.85 at 10 to 12.5 months (n = 109; p < .01), suggesting that the HINT, the newer of the two measures, is valid in determining motor delays. Each test has advantages and disadvantages, and practitioners should determine which one best meets their infant assessment needs.
