Aberrant Behavior Checklist [1] 
[Units: Units on a scale]
Mean (Standard Deviation)
ABC Irritability S   25.3  (5.1) 
ABC Hyperactivity   31.8  (5.8) 
ABC Social Withdrawal   16.6  (11.8) 
ABC Stereotypy   12.7  (5.6) 
ABC Inappropriate Speech   6.8  (5.1) 
[1] The Aberrant Behavior Checklist (ABC) is a 58-item measure of maladaptive behaviors and is used as a measure of drug effects. The ABC has 5 subscales: Social Withdrawal (16 items) ranging from 0 (not at all) to 48 (severe), Irritability (15 items) ranging from 0 (not at all) to 45 (severe), Inappropriate Speech (4 items) ranging from 0 (not at all) to 12 (severe), Hyperactivity (16 items) ranging from 0 (not at all) to 48 (severe), and Stereotypy (7 items) ranging from 0 (not at all) to 21 (severe). Items are rated from 0 (not at all) to 3 (severe).
Clinical Global Impressions - Severity [1] 
[Units: Units on a scale]
Mean (Standard Deviation)
 4.5  (0.5) 
[1] The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill.
Children's Yale-Brown Obsessive Compulsive Scale Modified for PDD [1] 
[Units: Units on a scale]
Mean (Standard Deviation)
 14.2  (4.6) 
[1] The CY-BOCS PDD has been utilized in a largescale clinical treatment study of repetitive behavior in idiopathic ASDs. CYBOCS-PDD scores range from 0 to 20 and measure repetitive/compulsive behavior and not obsessions. Higher score indicate worse outcome.
Social Responsiveness Scale [1] 
[Units: Units on a scale]
Mean (Standard Deviation)
 124.5  (26.7) 
[1] The 65-item SRS is a standardized measure of the core symptoms of autism. Each item is scored on a 4-point Likert scale. The score of each individual item is summed to create a total raw score. A total scores results are as follows: 0-62: Within normal limits 63-79: Mild range of impairment 80-108: Moderate range of impairment 109-149: Severe range of impairment
