Pediatric Evaluation of Disability Inventory (PEDI)
No updates have been make to the PEDI test since the previous blog post on March 15, 2017. Below is a pricing update for the PEDI-CAT.
Costs:
PEDICAT for Windows operating systems is $89.00
PEDICAT for iPad operating systems is $399.00

Article Review:
Dumas, H.M., Fragala-Pinkham, M., et al. Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT) and Alberta Infant Motor Scale (AIMS): Validity and Responsiveness. Phys Ther (2015) 95 (11): 1559 – 1568.
The article aims to look at the concurrent validity of the PEDI-CAT (which is the online version of the PEDI outcome measure) by comparing the mobility domain of the test to the Alberta Infant Motor Scale (AIMS). The researchers noted that previous studies (though limited) have validated the psychometric properties of the test in a general sense, there has been no research up to this point that has looked at more age specific properties. The article looks at 53 infants and young children in a post-acute hospital setting. Several physical therapists were involved with implementing the tests to the children with each child receiving a PEDI-CAT and AIMS examination by the same therapist. The researchers than compared the age percentile calculated for each outcome measures and found that the outcome similarities were statistically significant and had a fair association from the PEDI-CAT to the AIMS. The researchers also noted there is no statistically significant difference between the two outcome measures with identifying motor delay.
Strengths of the article were that: each child had the same therapist perform all of the exams, they compared the PEDI-CAT to a test that has already been shown valid, and they compared the PEDI-CAT to a test that examined similar tasks as the mobility domain of the PEDI-CAT. Weaknesses of the article were that: they did not use one therapist to administer all of the tests and they had a relatively small sample size of participants. Overall, the article demonstrated that the PEDI-CAT is shown to have concurrent validity for the test results, but to use the results cautiously since little research has been done so far to assess this outcome measure.

This seems expensive, especially that the ipad version is 3 times the cost, this is crazy! At least it was proven to be as valid and reliable as the AIMS, I wonder what the cost of the AIMS is? If that test is much cheaper and just as reliable then it seems like it may be a better option and more applicable.
I am not sure of the cost of the AIMS. One thing to consider is use, the AIMS primarily assess motor function whereas the PEDI looks at motor function and other functional domains as well.
Great summary and comments!!
Cost is definitely a factor when considering a measure. The PEDI is also available in a book and score sheets that are pretty low tech and affordable. Matt is correct, the AIMS and the PEDI measure different items/activities in very different populations. Check out the age limits for each of these measures!
