“…Indeed, reading difficulties and CD were shown to be unrelated except by their common correlation with the attention deficits reported in ADHD (Rapport, Scanlan & Denney, 1999;Carroll, Maughan, Goodman & Meltzer, 2004). Furthermore, despite the well-documented association between ADHD and reading problems (Merrell & Tymms, 2001;Hinshaw, 1992), a growing literature has documented that it is the inattentive subtype of ADHD, when compared with the hyperactive subtype, which correlates more strongly with the reading difficulties of school-aged children (Willcutt & Pennington, 2000a;McGee, Prior, Williams, Smart & Sanson, 2002). Importantly, longitudinal studies have presented evidence that inattentive behavior during kindergarten predicted reading achievement by the end of elementary school (Duncan et al, 2007;Rabiner & Coie, 2000), and that inattention reported at elementary school significantly predicted long-term educational attainment at age 22-23 (Pingault et al, 2011).…”
