Integrating systems of care in California for youth with severe emotional disturbance. I. A descriptive overview of the California AB377 evaluation project

“…These scores range from 0 (lowest overall functioning) to 90 (highest overall functioning) and represent the global severity of symptoms as reported by the admitting clinician.
