The ASAM Criteria text and ASAM CONTINUUM are companion text and application. The text delineates the dimensions, requirements and decision rules that comprise ASAM’s criteria. ASAM CONTINUUM provides the approved structured interview to guide the assessment and calculate the complex decision tree to yield suggested levels of care for adults. The text and ASAM CONTINUUM should be used in tandem: the text to provide the background and guidance for proper use of ASAM CONTINUUM, and ASAM CONTINUUM to enable comprehensive, standardized evaluation. Effective, reliable treatment planning requires that both be used together.
