Childhoood Autism Rating Scales-2 (CARS-2)
Time Frame: 24 weeks
|
Two 15-item rating scales completed by the clinician (each designed for a different population); and an unscored Parent/Caregiver Questionnaire
|
24 weeks
|
Secondary Outcome Measures

Measure Description |
Time Frame |
|---|---|---|
|
Aberrant Behavior Checklist-2 (ABC-2)
Time Frame: 55 weeks
|
Scoring scale range from 1-3 for a 58 question, 5 behavior category assessments.
All categories summed for individual total scores (7-48).
Individual total scores determine severity (the higher, the more severe).
|
55 weeks
|
|
Social Responsiveness Scale-2 (SRS-2)
Time Frame: 55 weeks
|
Total Score; Scores for 5 Treatment Subscales; Scores for 2 DSM-5 Compatible Subscales
|
55 weeks
|
|
Parent Global Impressions-III (PGI-III)
Time Frame: 55 weeks
|
19 question assessment evaluating parent observations from "much worse" to "much better".
|
55 weeks
|
|
Gastrointestinal Symptom Rating Scale (GSRS)
Time Frame: 55 weeks
|
Contains 15 items, uses a seven-graded Likert scale, where 1 represents the most positive option and 7 the most negative one.
|
55 weeks
|
|
Gastrointestinal Stool & Symptom Questionnaire for Autism (GSSQA)
Time Frame: 55 weeks
|
17 item assessment evaluating GI symptoms on a scale from "Not at all" to "Almost always".
|
55 weeks
|
|
Reynolds Intellectual Assessment Scales-2-Nonverbal (RIAS-2-NV)
Time Frame: 55 weeks
|
IQ test with 8 sub-categories.
Scores from each category summed, then indexed
|
55 weeks
|
|
Autism Diagnostic Interview-Revised (ADI-R)
Time Frame: 55 weeks
|
The ADI-R provides a diagnostic algorithm for autism as described in both the ICD-10 and DSM-IV.
The instrument focuses on behavior in three main areas: qualities of reciprocal social interaction; communication and language; and restricted and repetitive, stereotyped interests and behaviors.
