Collective Efficacy

Collective Efficacy is a 10-item measure of neighborhood social cohesion and trust, and the ability or willingness of neighbors to intervene for the common good of the neighborhood (informal social control). In particular, respondents are asked to consider the quality of their neighborhood and rate the likelihood of different hypothetical situations occurring (e.g., people fighting). This measure of collective efficacy is widely used in criminology and social science research.
