“…Diagnoses in the chronic medical condition group included cancer ( n = 27), diabetes ( n = 40), heart disease ( n = 44), epilepsy ( n = 107), and migraine ( n = 436). These conditions have been noted to have similar impact on school ( Barrett & Sachs, 2006 ; Berg & Linton, 2009 ; Brown, 2004 ; Clay, 2004 ; Delamater, Brady, & Blumberg, 2004 ; Phelps, 2006 ; Powers, Patton, Hommel, & Hershey, 2003 ; Robinson et al, 2010 ; Rovet & Fernandes, 2004 ; Taras & Potts-Datema, 2005 ) and multiple previous studies have used a similar list of diagnoses with the non-categorical approach for research ( Cadman, Boyle, Szaltmari, & Offord, 1987 ; Fowler et al, 1985 ; Maslow et al, 2011 ; Meijer et al, 2000 ; Thies, 1999 ). The healthy group ( N = 897) was randomly chosen from all who identified as having no history of health concerns at the Wave IV data collection point.…”
