Neighborhood processes have been shown to influence child maltreatment rates, and accordingly neighborhood-based strategies have been suggested as helpful in intervening in and preventing child maltreatment. Although child-welfare workers are at the forefront of child maltreatment work, little is known about the extent to which their perspectives on neighborhood processes related to child maltreatment align with those of neighborhood residents. The current study examined the views of neighborhood residents (n = 400) and neighborhood-based child-welfare workers (n = 260) on 2 neighborhood process measures: social disorder and collective efficacy. Because social disorder is viewed as a risk factor for child maltreatment and collective efficacy is viewed as a protective factor, child-welfare workers and residents of neighborhoods need to reach a common understanding of these factors in order to reach agreement on the safety of children in these neighborhoods. The samples of neighborhood residents and child-welfare workers were nested within 20 neighborhoods in Cleveland, Ohio. Multilevel modeling taking into account individual and neighborhood characteristics indicated that child-welfare workers consistently tended to perceive higher social disorder and lower collective efficacy compared to residents. Neighborhood characteristics were associated with residents' and child-welfare workers' perspectives on social disorder in different ways. Differences between residents and child-welfare workers concerning perceptions of neighborhood processes have implications for better understanding the context and improving the effectiveness of neighborhood-based interventions to prevent child maltreatment.
