- Hour 4 Swanson, Kotkin, Alger, M-Flynn and Pelham Scale for Deportment (SKAMP-Deportment) [ Time Frame: Hour 4 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of the child's impairment in classroom behavior. The SKAMP-Deportment (SKAMP-D) (range: 0, 36) is a sum of ratings on 6 deportment items (interacting with other children, interacting with adults, remaining quiet, staying seated, complying with the teacher's directions, and following the classroom rules). Each item was rated on a 7-point impairment scale (0=normal, 6=maximum impairment), with higher scores indicating more severe symptoms.
- Hour 4 Swanson, Kotkin, Alger, M-Flynn and Pelham Scale for Attention (SKAMP-Attention) [ Time Frame: Hour 4 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of the child's impairment in classroom behavior. The SKAMP-Attention (SKAMP-A) (range: 0, 42) is a sum of the ratings on 7 attention items (getting started, sticking with tasks, attending to an activity, making activity transitions, completing assigned tasks, performing work accurately, and being neat and careful while writing or drawing). Each item was rated on a 7-point impairment scale (0=normal, 6=maximum impairment), with higher scores indicating more severe symptoms.
- Hour 4 Swanson, Kotkin, Alger, M-Flynn and Pelham Scale for Composite (SKAMP-Composite) [ Time Frame: Hour 4 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of the child's impairment in classroom behavior. A composite score (range: 0, 78) for the SKAMP variable (13 items total) was obtained by summing the SKAMP-D and SKAMP-A subscale scores. A lower score was preferable, as a higher score represented greater behavioral impairment.
- Hour 5.5 Test of Variables of Attention (TOVA) ADHD Composite Cutoff Score [ Time Frame: Hour 5.5 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
The TOVA (range: unbounded) is a computerized, visual continuous performance test providing a measure of attention. The stimulus, presented for 100 milliseconds (ms) at the rate of 30 per minute, is a computer-presented square containing a square hole near the top (target) or bottom (non-target) edge. Higher scores indicate better performance, lower scores indicate worse performance. Clinical interpretation: an ADHD scores of -1.80 or lower (<= -1.80) are considered not within normal limits scores above -1.80 (> -1.80) are considered inconclusive (meaning, neither like-ADHD nor like-normal).

During this test the investigator pointed to a longer and longer series of windows on a card at the rate of 1 location per second, and then the child was asked to reproduce the sequence exactly in reverse order. One point was given for each correctly recalled sequence, and the test was discontinued after 3 consecutive errors.

- Hour 5.5 Wechsler Intelligence Scale for Children - 3rd ed. (WISC-III-PI) Digit Span Backwards [ Time Frame: Hour 5.5 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
Each child individually was given a sequence of numbers with the sequence becoming progressively longer. The child was then asked to repeat the digits in the same sequence, either forwards or backwards. Each sequence length was attempted twice. The test was complete after failure on both trials of any sequence length. One point was awarded if the participant passed only 1 trial of a sequence length. Zero points were given if the participant failed both trials. The maximum raw scores were 16 forwards and 14 backwards. A higher score was indicative of better recall and attention (range: 0, 14).

The test includes subtests: writing from memory or dictation the letters of the alphabet in order, single digit-numbers out of order, selected words, and copying selected letters, words, and sentences. Each subtest was scored from zero (poorly formed letters) to 3 (perfectly formed letters). 100 is the normal mean; scores lower than 100 indicate performance worse than normal, scores above 100 indicate performance better than normal.
- Hour 3.5 Dynamic Indicators of Basic Early Literacy Skills (DIBELS) [ Time Frame: Hour 3.5 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
The DIBELS (range: 0, 376), used to assess reading fluency, consists of standardized, individually administered measures of early literacy development. These short (1 minute) fluency measures were developed based upon essential early literacy domains to assess development of phonological awareness, alphabetic understanding, and automaticity and fluency. Only the paragraph fluency component of an age/grade-appropriate DIBELS was used. A higher score indicated better performance, as it represented that the subject orally read a greater number of words correctly within the time allowed.

- Hour 3.0 Grammar Task [ Time Frame: Hour 3.0 of the Lab School Day During the Double-Blind Assessment Period ] [ Designated as safety issue: No ]
This task, presented once during a laboratory school day, was designed to index "attention to detail" by determining how many grammatical mistakes each child could identify and circle in a brief paragraph. The errors were not difficult to identify and were designed to show attention to task, not comprehension. A higher number of errors identified, of those possible, was indicative of better attention - identification of grammatical errors(range: 0, 1 represents correct responses divided by the number of possible responses).
