“…In many studies, the two concepts have been theoretically and operationally integrated into the collective efficacy concept, which highlights both the social bonding and collective functioning of geographically bounded communities (Sampson et al, 1997). In fact, collective efficacy has been linked to a host of important outcomes, such as youth violence (Morenoff, Sampson, & Raudenbush, 2001;Sampson et al, 2005), adolescent development (Browning, Burrington, Leventhal, & Brooks-Gunn, 2008;Emory, Caughy, Harris, & Franzini, 2008), and adult mortality (Wen et al, 2005). However, the current study shows that perhaps, under some circumstances, the two key components of collective efficacy should be separately examined because they may have different impacts on the outcome of interest.…”
