Policy advocacy by nonprofits has attracted substantial scholarly interest in recent years. Although considerable empirical studies have examined factors influencing nonprofit participation in policy advocacy, the existing evidence remains inconsistent as to what factors influence nonprofits to engage in policy advocacy and to what extent. The present study conducts a meta-analysis to quantitatively synthesize existing studies on the organizational antecedents of nonprofit advocacy engagement. Through systematically reviewing 46 studies and aggregating 559 effect sizes on 17 organizational predictors, the study finds organizational size, professionalization, board support, constituent involvement, knowledge about laws, government funding, private donations, foundation funding, collaboration, and negative policy environment have positive and significant relationships with a nonprofit’s level of advocacy engagement. The study contributes a clear knowledge base to guide future nonprofit advocacy research and practice.
