The purpose of this research was to evaluate the effectiveness of the Solution-Based Casework (SBC) model for child welfare practice. Method: Two case review studies were conducted. The first study compared 48 cases from two worker groups differing in degree of training and implementation of the SBC model. The second study compared the outcomes of 100 high-risk cases based on implementation level of the SBC model. Results: These two studies found that SBC can be implemented across cases differing in type of maltreatment, comorbid factors, and other demographic variables. Results indicated that workers were more actively involved in case planning and service acquisition for families when SBC was implemented. Families were significantly more compliant with casework requirements and achieved more case goals and objectives. The model was particularly effective for families with a history of chronic involvement with the child welfare system. Conclusions: This research supports the effectiveness of SBC for promoting the worker-client relationship and goal achievement for complex child welfare cases.
