“…Whatever their title and specific goals, or even their theoretical basis, one cannot help but admit that this kind of education has produced impressive outcomes during the past decades concerning the improvement of students' social, emotional, and coping skills, as pointed out by international organizations (UNESCO, 2004;WHO, 2003) and shown by various meta-analyses (Durlak, Weissberg, Dymnicki, Taylor & Schellinger, 2011;Diekstra & Gravesteijn, 2008;Payton et al, 2008;Wilson, Gottfredson & Najaka, 2001;Durlak & Wells, 1997). Such programmes have been found to a) improve self-esteem (O'Mara, Marsh, Craven & Debus, 2006;Haney & Durlac, 1998), b) prevent depression (Merry, McDowell, Hetrick, Bir & Muller, 2004;Forness, Serna, Kavale & Nielsen, 1998) and other mental health problems (Greenberg, Domitrovich, & Bumbarger, 2001), c) prevent drug use (Faggiano et al 2005;Tobler et al, 2000) and alcohol and tobacco use (Botvin, Griffin, Paul, & Macaulay, 2003), d) enhance emotion management and self-control (Gansle, 2005;Barrett, 2004;Kusché & Greenberg, 1994), e) help children resolve interpersonal conflicts (Geller, 1999;Grossman et al, 1997;Kusché & Greenberg, 1994;Shure & Spivack, 1982) and maintain healthy relationships (Beelmann & Lösel, 2006;Englander-Golden, Jackson, Crane, Schwarzkopf & Lyle, 1989) and e) reduce violent behavior (Hahn et al, 2007;Wilson & Lipsey, 2007;Wilson, Lipsey & Derzon, 2003;Catalano, Berglund, Ryan, Lonczak, & Hawkins, 2004).…”
