“…Several studies conducted in the general education system (i.e., regular education classes and resource rooms) have demonstrated that adolescents with CD frequently present a low level of global self-esteem (Al-Talib & Griffi n, 1994;Barry, Frick, & Killian, 2003;Bynum & Weiner, 2002;Donnelan, Trzesniewski, Robins, Moffi tt, & Capi, 2005;Harter, Whitesell, & Junkin, 1998;Hay, 2000;Levy 1997Levy , 2001Sprott & Doob, 2000) and a similar level of global physical self-perceptions (Al-Talib & Griffi n, 1994;Hay, 2000;Levy, 1997Levy, , 2001 in comparison with normally achieving (NA) students. However, other studies explain that when adolescents with CD are schooled in a segregated education system (i.e., segregated classes in a specialized establishment) they tended to present lower levels of global self-esteem (Al-Talib & Griffi n, 1994;Evans, Levy, Sullenberger, & Vyas, 1991;Levy 1997Levy , 2001Maïano, Ninot, Bilard, & Albernhe, 2002;Sweitzer, 2005), global physical self-perceptions (Al-Talib & Griffi n, 1994;Levy 1997Levy , 2001Maïano et al, 2002;Sweitzer, 2005), and perceived physical condition and sport competence (Maïano et al, 2002) than NA students.…”
