Each of the tests was chosen based on the recommendation of our consultant and certified behavioral analyst, Doreen Granpesheh PhD. These tests are deemed most likely to detect change with treatment intervention and when appropriate (e.g., ADOS) will be administered by ACH Pediatric Psychologists. The ADOS behavior test will be videotaped. A second behavior analyst will evaluate a random set of these video recordings to confirm inter-rater reliability.
