This study examined the relationship between intimate partner violence (IPV) relationship dissolution and neighborhood concentrated disadvantage, ethnic heterogeneity, residential instability, collective efficacy, and legal cynicism. Data from the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal survey were used to identify 658 cases of IPV in Wave 1. A generalized boosting model (GBM) was used to determine the best proximal predictors of relationship dissolution from the longitudinal data. Controlling for these predictors, logistic regression of neighborhood characteristics from the PHDCN community survey was used to predict IPV relationship dissolution in Wave 2. Counterintuitively, the authors find that neighborhoods high in legal cynicism have a greater likelihood of IPV relationship dissolution, controlling for other variables in the logistic regression model. However, analyses did not find that IPV relationship dissolution was related to neighborhood concentrated disadvantage, ethnic heterogeneity, residential instability, and collective efficacy.
