“…Similarly, duration of involvement has been shown to positively influence youth (1) psychological adjustment gained through the formation of high-quality relationships with supportive adult leaders and prosocial peers (Fredricks & Eccles, 2005), (2) physical, cognitive, emotional, and interpersonal skills acquired through continuous practice of these skills in the OST program context (Bohnert et al, 2010), and (3) identity formation shaped through a strengthened commitment to one, or more, OST programs (Fredricks & Eccles, 2005). In all, intensity and duration of involvement increase youth exposure to program curriculum (Eccles & Roeser, 2011;Hansen, Larson & Dworkin, 2003;Larson, Hansen & Moneta, 2006;Lerner, von Eye, Lerner & Lewin-Bizan, 2009), which, in turn, increases the likelihood of the successful transmission of the program's mission to the youth involved in the program.…”
