“…These activities, taking place both at school (extracurricular activities) and in the community, are characterized by the presence of an adult leader, rule-guided engagement, regular participation schedules, and an emphasis on skill-building (Larson, 2000;Mahoney & Stattin, 2000). Several studies have shown that participating in these activities is associated with positive educational trajectories (Darling, 2005;Eccles & Barber, 1999;Mahoney, Cairns, & Farmer, 2003), lower rates of both risky behaviors (Eccles & Barber, 1999;Mahoney, 2000) and internalizing problems (Barber, Eccles, & Stone, 2001;Fredricks & Eccles, 2006b), and higher rates of civic engagement (Fredricks & Eccles, 2006b;Gardner, Roth, & Brooks-Gunn, 2008;Zaff, Moore, Papillo, & Williams, 2003). To explain these benefits, researchers have suggested that organized activities are likely to promote positive developmental experiences, such as identity formation, initiative development, skill building, and relations with activity peers and leaders (Denault & Poulin, 2008;Larson, Hansen, & Moneta, 2006;Lerner, Almegiri, Theokas, & Lerner, 2005;Mahoney, Larson, & Eccles, 2005).…”
