Objective: This article describes a case management approach that incorporates an ecosystem perspective and provides practitioners with a method of interaction between various ecosystems. Resource integration is adopted to create change, coordination, and communication and thereby increase the efficiency of resource usage. Methods: In this case, long-term marital violence against women and intervention services for battered women were analyzed in relation to the process of rebuilding their lives. This study found that the means in which multiple social workers operate under ecosystem-based approaches to provide case management services is complex and could be rendered more systematic. Efficient services and links to resources were developed in relation to life, work, violence, economic recovery and stability, and the ability to live independently with children. Conclusions: This study drew three conclusions. The first is that social workers should be allowed effective control over resources and be able to use them properly to maximize efficiency. The second is that the effectiveness of cross-team professional cooperative services must be enhanced. The third is the importance of social support in life reconstruction for battered women. Recommendations: First, case management resources should be used effectively to prevent the need for intervention; managing multiple cases causes distress in social workers. Second, case managers should be provided with more institutional support. Finally, the importance of social support in life reconstruction for battered women should be emphasized.
