The ADHD Rating Scale is an 18-item scale directly derived from DSM-IV criteria for Attention Deficit Hyperactivity Disorder. The ADHD Rating Scale-IV is completed by the parent and scored by a clinician. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). If 3 or more items are skipped, the clinician should use extreme caution in interpreting the scale. The total score can range from 0 to 54, with a higher score indicating greater severity

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

The Peabody Picture Vocabulary Test is one of the most commonly used assessment tests that measure verbal ability in standard American English vocabulary. This test has been nationally standardized using examinees from various age groups, from children to adults. Thus, the raw scores are equated to mental age, using the norms obtained from standardization. The total standard scores range from 40 (worse receptive vocabulary) to 160 (better receptive vocabulary). The scores can also be converted to percentile rank.

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.

ERK activations times, as defined as the time in minutes for ERK phosphorylation to reach the half maximal level.

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).

The Children's Yale-Brown Obsessive Compulsive Scales-Modified (CY-BOCS) is a 5-item, semi-structured clinician rating scale modified designed to rate the current severity of repetitive behavior in children and adolescents with PDD. Once the current repetitive behaviors are identified, they are separately rated on 5 items: Time Spent, Interference, Distress, Resistance, and Control. Each of these items is scored on a 5-point scale form 0 (least symptomatic) to 4 (most symptomatic). The CY-BOCS yields a Total Score from 0 to 20 and is sensitive to change.

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.
