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.

About this study

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.

Primary outcomes

  1. Swanson, Nolan, and Pelham Checklist for DSM-IV (SNAP)- Parent Rating of Inattention

    Time frame: 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).

  2. Swanson, Nolan, and Pelham Checklist for DSM-IV (SNAP)- Parent Rating of Hyperactivity-impulsivity

    Time frame: 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).

  3. Swanson, Nolan, and Pelham Checklist for DSM-IV (SNAP)- Teacher Rating of Inattention

    Time frame: Week 16 (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 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).

  4. Swanson, Nolan, and Pelham Checklist for DSM-IV (SNAP)- Teacher Rating of Hyperactivity-impulsivity

    Time frame: Week 16 (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 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).

  5. Wechsler Individual Achievement Test-III (WIAT-III) Word Reading Subtest

    Time frame: Week 16 (End of Active Treatment Phase) and Follow-Up

    The WIAT-III is an individually-administered test of academic achievement. In the Word Reading subtest students read a list of increasingly difficult words. Scores reported here are standardized scores with a mean of 100 and standard deviation of 15.

  6. Wechsler Individual Achievement Test-III (WIAT-III) Pseudoword Decoding Subtest

    Time frame: Week 16 (End of Active Treatment Phase) and Follow-Up

    The WIAT-III is an individually-administered test of academic achievement. In the Pseudoword Decoding subtest students read a list of increasingly difficult nonsense words as a test of their ability to use phonics to decode unknown words. Scores reported here are standardized scores with a mean of 100 and standard deviation of 15. Higher scores represent a better outcome.

Secondary outcomes

  1. Wechsler Individual Achievement Test-III (WIAT-III) Reading Comprehension Subtest

    Time frame: 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.

  2. Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency Subtest (DIBELS ORF)

    Time frame: 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).

  3. Test of Word Reading Efficiency (TOWRE) - Sight Word Efficiency

    Time frame: 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.

  4. Test of Word Reading Efficiency (TOWRE) - Phonemic Decoding Efficiency

    Time frame: 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.

  5. Test of Silent Reading Fluency and Comprehension (TOSREC)

    Time frame: 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.
