Reading ICARD: Interventions for Children With Attention and Reading Disorders

The objective of this randomized clinical trial is to address unanswered questions about the relative effectiveness of treatments for children with both Attention Deficit Hyperactivity Disorder (ADHD) and significant reading difficulties (RD). The study evaluates attentional and word reading outcomes for students with both conditions when provided with either (a) ADHD treatment alone, (b) RD treatment alone, or (c) the combination of ADHD and RD treatment.

Gedetailleerde beschrijving

The objective of this randomized clinical trial is to address unanswered questions about the relative effectiveness of treatments for children with both Attention Deficit Hyperactivity Disorder (ADHD) and significant reading difficulties (RD). The study evaluates attentional and word reading outcomes for students with both conditions when provided with either (a) disorder-specific ADHD treatment (carefully managed medication + parent training), (b) disorder-specific RD treatment (intensive, individualized reading instruction), or (c) the combination of ADHD and RD treatment. The study aims to address the relative benefits of providing either disorder-specific ADHD or RD treatment alone and providing the combined treatment. The investigators hypothesize that the combined treatment approach will result in better outcomes in terms of both word reading/decoding and a reduction in ADHD symptoms than either of the disorder-specific treatments alone. Treatment will last for 16 weeks, with assessment prior to and following treatment and some measures collected regularly throughout the intervention periods.

Experimenteel: Intensive Reading Instruction
Specialized phonologically-based reading instruction provided by well-trained tutors either individually (one-on-one) or to groups of two students for 45 minutes, four days per week, for 16 weeks. The instructional approach includes an individualized combination of published programs targeting word reading and decoding; reading fluency; and reading comprehension.
Gedragsmatig: Intensive reading instruction
Individualized phonologically-based instruction delivered 4 days per week for 45 min. per day by a highly trained tutor.
Experimenteel: ADHD Intervention
Carefully-managed medication and behavioral parent training. Medication treatment begins with a four-week titration period, beginning with a trial of methylphenidate. If benefit is insufficient or side effects are intolerable, the physician may initiate a trial of mixed salt amphetamine, followed by either Atomoxetine or Guanfacine. When the optimum medication and dosage is determined the child returns for monthly medication maintenance visits until the end of the 16-week intervention period. Parent training consists of nine group sessions provided by a psychologist addressing ADHD and its treatment, principals of behavior modification, and evidence-supported practices for managing behavior.

Tijdsspanne
Swanson, Nolan, and Pelham Checklist for DSM-IV (SNAP)- Parent Rating of Inattention
Tijdsspanne: 16 weeks (end of Active Treatment phase), and follow-up
Rating Scale of ADHD symptomology completed by parents and teachers. Raters evaluate how well each DSM-IV (Diagnostic and Statistical Manual) ADHD symptom describes a child on a four-point Likert scale (0=Not at all, 1=Just a little, 2=Quite a bit, 3=Very much). The measure shows adequate internal consistency (.94) and test-retest reliability (Bussing et al., 2008; Gau et al., 2008).

Tijdsspanne
Wechsler Individual Achievement Test-III (WIAT-III) Reading Comprehension Subtest
Tijdsspanne: Week 16, End of Active Treatment Phase
The WIAT-III is an individually-administered test of academic achievement. This subtest involves reading sentences and longer passages and then answering a set of literal and inferential comprehension questions about the text. Scores reported here are standardized scores with a mean of 100 and standard deviation of 15. Higher scores represent a better outcome.
Week 16, End of Active Treatment Phase
Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency Subtest (DIBELS ORF)
Tijdsspanne: Week 16 (End of Active Treatment Phase) and Follow-Up
DIBELS ORF measures oral reading fluency in connected text. Students are presented with a passage on their grade level to read orally, and the score is the number of words of the passage read correctly in a one-minute period. Students in this study read two passages at each test administration, and the mean score for the two passages was the dependent variable analyzed. A research synthesis of studies reporting psychometric properties for DIBELS ORF determined that reliability coefficients in these studies exceeded .80 and that the measure demonstrated moderate to high concurrent and predictive validity across studies (Goffreda & DiPerna, 2010).
Week 16 (End of Active Treatment Phase) and Follow-Up
Test of Word Reading Efficiency (TOWRE) - Sight Word Efficiency
Tijdsspanne: Week 16 (End of Active Treatment Phase) and Follow-Up
The TOWRE Sight Word Efficiency subtest measures fluency of reading words in lists. The raw score is the number of words or nonwords identified correctly in 45 seconds. Standard scores with a mean of 100 and standard deviaion of 15 are reported here. Higher scores represent a better outcome.
Week 16 (End of Active Treatment Phase) and Follow-Up
Test of Word Reading Efficiency (TOWRE) - Phonemic Decoding Efficiency
Tijdsspanne: Week 16 (End of Active Treatment Phase) and Follow-Up
The TOWRE Phonemic Decoding Efficiency measures the student's fluent decoding of nonsense words that follow the spelling rules of the English language. The raw score is the number of nonwords identified correctly in 45 seconds. Standardized scores with a mean of 100 and standard deviaion of 15 are reported here. Higher scores represent a better outcome.
Week 16 (End of Active Treatment Phase) and Follow-Up
Test of Silent Reading Fluency and Comprehension (TOSREC)
Tijdsspanne: Week 16, End of Active Treatment Phase
The TOSREC measures sentence-level comprehension and silent reading fluency. It is a sentence verification task; children are presented with a list of sentences and must tell whether they are true or false. Items are based on common knowledge (e.g., All apples are blue). The raw score is the number of items answered correctly in 3 minutes. Standardized with a mean of 100 and standard deviation of 15 are reported here. Higher scores represent a better outcome.
