What is the CASII?

The Child and Adolescent Service Intensity Instrument (CASII) is a standardized assessment tool that provides a determination of the appropriate level of service intensity needed by a child or adolescent and his or her family. It is unique in its capacity to determine service intensity need, guide treatment planning, and monitor treatment outcome in all clinical and community-based settings.

The CASII is developmentally informed and developed on the foundation of a System of Care approach -- embracing individualized service planning, supporting the use of intensive care coordination or wraparound planning teams when indicated, and providing a broad service array. CASII recognizes use of home and community-based services and natural supports can provide increased service intensity instead or relying just on “bricks and mortar” to achieve higher levels of service intensity.

The CASII is applicable to children living in the community with their parents or extended family, to children in foster care, and to children in institutional settings. The CASII assesses the service intensity needs of children and adolescents presenting with psychiatric, substance use, medical and/or developmental concerns. It incorporates holistic information on the child within the context of his/her family and community, assessing service intensity needed across six key dimensions: Risk of Harm, Functional Status, Co-Occurring Conditions, Recovery Environment, Resilience/Response to Services, and Involvement in Services.

The CASII links the results of a clinical assessment with a defined level of service intensity, using a clinically derived and empirically tested algorithm. It is a user-friendly and clinically relevant tool. The CASII is culturally informed and supports active participation by child and family. The CASII can be used at all stages of intervention and is designed for use in all child-serving systems (behavioral health, physical health, education, child welfare, juvenile justice, substance use, and developmental) to facilitate integrated attention to the child’s needs. It is diagnosis independent in its application and it promotes effective communication between providers and systems and informs clinicians’ engagement with the child, family, and community.
