Which case management model allows for involvement from family members or volunteers?

The responsibility-based case management model emphasizes collaboration and the idea that multiple stakeholders can play a role in client care. This model allows for the active involvement of family members and volunteers, recognizing the support systems surrounding the client as integral to the overall treatment and recovery process. By incorporating these individuals, responsibility-based case management leverages a broader network of support that can aid in addressing the client's needs more holistically and effectively.

In contrast, the other models may focus more on specific roles within professional boundaries and may not prioritize or facilitate the same level of inclusion from non-professional supporters. For instance, role-based case management typically emphasizes defined professional responsibilities, while organizational-based case management centers on the structure and resources of the organization itself. Professional-based case management primarily revolves around the expertise of trained professionals, which might limit the direct involvement of family members or volunteers in the case management process. Thus, the correct answer highlights the unique nature of responsibility-based case management in fostering a more inclusive approach to support.
