Intensive Home Based Treatment (IHBT) is a critical component of the continuum of community-based behavioral healthcare for youth with serious emotional disorder (SED) and their families. Yet despite being used nationwide at costs of over $100 million annually in some states, a well-vetted, research-based set of quality standards for IHBT has yet to be developed. The current project aimed to define program and practice standards for IHBT, drawing upon literature review, expert interviews, and a systematic "Delphi" process engaging over 80 participants, including IHBT developers, experts in evidence-based youth mental health, youth and family advocates, IHBT providers, and state policymakers. After two rounds of quantitative and qualitative input, adequate consensus was achieved on 32 IHBT Program Standards and 43 IHBT Practice Standards. These standards hold potential for informing efforts such as development of state regulations, provider contracts, memoranda of agreement, and training and workforce development initiatives. Translation of the quality standards into measurement strategies holds potential for providing a method of continuous quality improvement across multiple levels as well as use in research on IBHT.
