Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed childhood disorders, with prevalence rates estimated at 8% (Froehlich et al. 2007). Several of the primary symptoms of ADHD relate to problems with temporal and materials organization (i.e. often has difficulty organizing tasks and activities, often loses things, is often forgetful, and often fails to finish school-work, chores, or duties; APA, 2000). In the school setting, problems with organization manifest as forgetting to complete or losing homework assignments, difficulties planning for the completion of long-term projects and studying for tests, and problems keeping class materials organized. These organizational difficulties become particularly problematic in middle school and can result in considerable academic impairment (Evans, Serpell, & White, 2005). Children with ADHD underachieve academically and are more likely than their peers to receive failing grades, be retained and to drop out of school (Barkley, Fischer, Edelbrock, & Smallish, 1990).
