Outcome Measures

Primary Outcomes (2)

  • Autism Diagnostic Observation Schedule, 2nd Edition (ADOS2)

    ADOS2 comparison scores are units on a scale of 0-10. A score of 7-10 was required for enrollment. A score of 7-10 is diagnostic for autism spectrum disorder (ASD). The higher the score, the more severe the core symptoms of autism spectrum disorder. Scores of 6 and below are considered off the ASD spectrum.

    6 weeks compared to baseline

  • Expressive Language

    Expressive One Word Picture Vocabulary Test (EOWPVT) scores are normalized for age. Typical language development produces a mean score of 100 with a standard deviation of 15. Outcomes for EOWPVT were expressed as the mean of the child-specific difference before and 6-weeks after treatment. For example, if the 6-week standard EOWPVT score was 59.6 and the baseline score was 63.8, the difference is -4.2 (= 59.6 - 63.8). A decrease in score at 6 weeks would corresponds to a decrease in language performance, while an increase, a positive difference, would reflect an increase.

Secondary Outcomes (4)

  • Aberrant Behavior Checklist (ABC)

    6 weeks compared to baseline

  • Autism Treatment Evaluation Checklist (ATEC)
