CONCERTA Lab School Study

PERMP (range: 0, 400) is a measure of academic productivity. These seatwork math tasks provide an objective measure of attention and accuracy in calculations. The level of difficulty is established on a screening math pretest. The subsequent laboratory school day assessments employed a series of 10-minute math tests (5 pages of 80 math problem each for a total of 400 problems available). Children were graded on the number of attempted problems. A higher number of problems attempted was indicative of greater attention to detail (higher score is preferable.)

The level of difficulty is established on a screening math pretest. The subsequent laboratory school day assessments employed a series of 10-minute math tests (5 pages of 80 math problem each for a total of 400 problems available). Children were graded on the number of correct problems. A higher number of problems correct, of those attempted, was indicative of greater accuracy.

The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of children 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.

The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of children 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.

The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of child 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.

The TOVA is a computerized, visual continuous performance test which provides measures 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. The first half of the TOVA requires that the child sustain attention while the second half requires inhibition of response to a non-target (observed range: -15.2, 5.2). An ADHD score of less than -1.80 is suggestive of ADHD.

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. The first half of the TOVA requires that the child sustain attention while the second half requires inhibition of response to a non-target. Mean response latency in msecs (observed range: -75.4, 129.5). Higher score indicates faster reaction time.

SD of response times (msecs) (observed range: -177.6, 132.9). Higher score indicates less variability.

WRAML-2 (range: 0, 28) is designed to evaluate a child's ability to learn and to memorize information, consists of 9 subtests from which 4 summary indexes can be calculated: verbal memory index, visual memory index, learning index, and general memory index. 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.

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).

Gray Silent Reading Test (GSRT) is a reliable, validated measure of reading comprehension administered in the group setting during the first half hour of the homework session (observed range: 0, 141). A higher score is preferable as it means more questions were answered correctly.

The THS-R is a standardized, untimed assessment designed to evaluate neurosensory integration manifested in manuscript and cursive writing. The test includes the 10 subtests: writing from memory the upper- and lower-case letters of the alphabet in order, writing from dictation the upper and lower-case letters of the alphabet out of 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). A higher score was preferable (observed range: 0, 118).

The DIBELS (observed range: 0, 212), 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. Children read 3 stories and completed the forms. A higher score was preferable and indicated a greater number of words read correctly in the time allowed

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).

Packet Activities: Assessment of ability to organize, listen to instructions, initiate task, complete task, and distractibility, by completing a word search, reading a short story for comprehension on a multiple choice test, reading a longer story for comprehension on a true/false test, decoding a mystery sentence, and completing various vocabulary assessments (word choice, homophones; base/root words, alphabetic order)(range: 0, 1 represents correct responses divided by the number of possible responses).
