The Circles of Care initiative emphasized the importance of developing an outcomes measurement plan that was consonant with the model system of care as well as community values and priorities. This analysis suggests that the Circles of Care grantees achieved this key programmatic objective, but that a major constraint was the tendency of funders, including the Substance Abuse and Mental Health Services Administration (the funder of Circles of Care), to mandate their own outcomes measurement plans. Funders are encouraged to balance their needs for commonality of measures across programs for their own evaluation purposes with the needs of service providers to utilize measures that meet their unique programmatic and community contexts.
