SAMHSA-funded community behavioral health programs have been evaluated by the National Outcome Measures (NOMs) since 2007. NOMs collects data on important aspects of client health including but not limited to mental health symptoms, functioning, and social connectedness through interviews with clients. Since its inception, NOMs has gone through a number of revisions. The most recent revision in 2021 has significant implications for program evaluation and research. This commentary provides an overview of the history of the NOMs followed by a review and critique of the recent changes with a particular attention to revisions in how responses are recorded. Implications of the NOMs are discussed with respect to its utility in evaluation, practice, and research.
