3. 2. Concept of “Collective Efficacy”  Combines notions of trust and cohesion with shared expectations for intervening on behalf of commonly held goals (e.g., supervision/monitoring of children)  Situational rather than global—task-specific construct  Does not assume that strong ties are necessary precondition for social efficacy  Moves beyond stocks of “social capital” by incorporating agency (taking action)
