"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" presents findings from research examining the influence of collective socialization, concentration of disadvantage, and prevalence of crime on conduct problems among African American youth residing in small cities and towns. Collective socialization is a process by which adults within a community social network influence children who are not their own by developing common behavioral expectations and sharing responsibility to insure conformance. The authors argue that one of the limitations of previous research on conduct problems has been omitted variable bias. Specifically, there has been a failure to examine community level variables as predictors of conduct problems. Results from the current study suggest a strong relationship between collective socialization and conduct problems. The authors acknowledge that although concentrated disadvantaged was not a significant predictor of conduct problems, it is often negatively associated with the existence of strong social networks within communities. Nevertheless, the results of this study can encourage small African American communities concerned with reducing the risk of conduct problems among their youth. Results suggest that concentrations of disadvantage and high crime within neighborhoods need not destine youth to involvement in acts that deviate from the social norm. Rather, mutual responsibility among community adults to reinforce prosocial behavior may be a significant determining influence. . [This "Data Trends" presents a summary of: Simons, L. G., Simons, R.
