This symposium presents findings relevant to the specification and delivery of integrated service models across child welfare, substance abuse and mental health settings. The symposium will present findings from evaluations of service integration models delivered in three diverse settings. The goal of the symposium is to unlock the “black box” of service integration, i.e., to identify the organizational and service characteristics that predict successful outcome. Recent research points to the value of access services (e.g., transportation and child care to facilitate client access to services), concrete services (e.g., housing) and matching services (that seek to match service delivery to client-expressed need for services). The papers will address these specific elements of programs in a review of implementation issues. Overall, each symposium participant will address the following three questions:

1. What are the organizational and service factors that characterize successful service integration efforts?

2. What specific components of service have a positive impact on key substance abuse and child welfare outcomes.

3. What specifically is the role of access services, onsite services, concrete services and matching services on the success of service integration efforts.
