The objective of this randomized clinical trial is to address the relative effectiveness of three distinct treatment strategies for children with comorbid ADHD and reading difficulties (RD). Despite the commonly observed overlap of ADHD and RD, little research has been conducted to determine whether established disorder-specific interventions, alone or in combination, are effective for addressing the needs of children with these co-occurring difficulties.
A sample of 216 elementary school children with ADHD and RD will be recruited across two sites and randomly assigned to one of three groups:
- Disorder-specific ADHD treatment (careful medication management + behavioral parent training).
- Disorder-specific RD treatment (highly intensive reading instruction)
- The combination of ADHD and RD treatments
Pre- and post-intervention measures will be used to evaluate a variety of behavioral and academic outcomes including ADHD symptomatology and word reading abilities. We address three specific aims:
- Aim 1 (disorder-specific treatment) involves the examination of the relative benefits of providing either disorder-specific ADHD or RD treatment to children with comorbid ADHD / RD.
- Aim 2 (combined treatment) addresses whether intensive reading intervention + careful medication management and behavioral intervention are more effective than either of these interventions alone for improving word reading and decreasing ADHD symptomatology in children with ADHD and RD.
- Aim 3 (moderators) involves the examination of variables that may moderate disorder specific treatment response in children with comorbid ADHD and RD. We expect that outcomes may be moderated by variables such as demographic variables (e.g., SES) and severity of ADHD and reading impairment.
