“…The late 1990s and early 2000s saw a surge in the publication of studies-clinical trials, large crossover studies, and single-subject designs-investigating the effectiveness of behavior modification for treating ADHD (e.g., Barkley et al, 2000;Chronis, Chacko, Fabiano, Wymbs, & Pelham, 2004;Hupp, Reitman, Northup, O'Callaghan, & LeBlanc, 2002;MTACG, 1999b;Pelham, Burrows-MacLean et al, 2005;SonugaBarke, Daley, Thompson, Laver-Bradbury, & Weeks, 2001). Perhaps the most well-known and widely cited study of treatments for ADHD is the Multimodal Treatment Study of ADHD (MTA; Conners et al, 2001;Jensen, 2001;MTACG, 1999aMTACG, , 1999bSwanson et al, 2001;Wells et al, 2000).…”
