CASII
Also written as: CASII — Child and Adolescent Service Intensity Instrument
A structured assessment tool used to determine appropriate level of care for youth mental health services.
Full Definition
The Child and Adolescent Service Intensity Instrument (CASII) is a multidimensional assessment tool designed to match youth with the most appropriate level of mental health care based on clinical need and functional impairment. The instrument evaluates six dimensions: risk of harm, functional status, co-morbidity, recovery environment, treatment acceptance, and treatment history. CASII generates recommendations for intensity of services ranging from outpatient therapy to residential treatment. The tool is widely used by managed care organizations, public mental health systems, and providers to ensure appropriate placement decisions and justify level of care determinations for authorization purposes.
Usage
Usage note: Ensure assessors are properly trained and certified in CASII administration for valid results.
