The researchers examined partnerships, designed to leverage limited resources and fulfill common missions, among state and local public health agencies and other organizations, agencies, and groups. In particular, they: 1) defined what good connectivity means in a public health partnership; 2) quantified good connectivity as percentile score measured against a standard; and 3) developed a tool to measure connectivity and document the analytic process through which the tool produces a connectivity score. The objective of this project was to develop a tool to allow public health partners to measure their multi-agency collaborations in order to strengthen them.
