The practice of policy advocacy has outpaced its theoretical development. Yet the
importance of a theoretical grounding for advocacy has increased as advocacy organizations
demand measures of efficacy, and theories of policy development need to account for advocates’
contributions to the process. This article begins to address these issues by developing a
conceptual framework of policy advocacy inputs, activities, and outcomes. Logic models of
practitioners’ advocacy programs were first synthesized into a general model. Then academic
theories from social sciences and especially policy studies were reviewed and applied to
hypothesize links between advocacy inputs and activities, and between activities and outcomes.
The result is a conceptual framework of policy advocacy to focus academic attention on this
topic, and to direct a research agenda.
